  • Wrangling the Wild West of MCP Servers

    Wrangling the Wild West of MCP Servers


    It’s getting real out here.

    Ever since I shared how autonomous AI Agents can monitor and heal the network on their own—yes, that one—I’ve gotten the same follow-up question in different forms:

    “Okay, Kareem, this all sounds great… but how do I actually build one of these Model Context Protocol (MCP) servers for my product?”

    Good news! If your product—like almost every product out there—has APIs, then chances are that you already have what you need.

    Enter: OpenAPI spec

    OpenAPI is a friendly contract for your APIs. You might’ve used it for Swagger docs, SDKs, Postman collections, or that one dusty codegen project from 2021. But here’s the twist: What if you passed that same OpenAPI spec to your AI agent?

    That’s it. That’s the key.

    One OpenAPI spec → one MCP Server → one AI-powered, access-controlled gateway to your product.

    And no, this isn’t a “12 steps and a DevRel miracle” situation. It’s just a few lines of Python and a FastMCP wrapper around your OpenAPI file. The magic? Your APIs get transformed into safe, role-based AI tools—without writing a single custom tool definition.

    Consider the following example:

    Meraki MCP Server Creation with Open API spec code

    You’re wrapping your existing OpenAPI spec with FastMCP, wiring in your authenticated client, and passing in your route-based ACLs. That’s how simple it is to go from “API docs” to “AI-ready, access-controlled MCP server.” 

    Build fast, govern smart

    In this new AI-powered world, speed is the easy part. Governance—that’s the harder lift.

    We don’t want to give the agent the keys to the kingdom. We want to provide it with a badge with just the proper access.

    That’s where RouteMap comes in—our ACLs for AI. With a simple list of patterns (regex for those who love pain and suffering) and HTTP verbs, you can declare what endpoints are accessible for different personas (NOC, Sysadmin, full access, and so on).

    Yes, it’s literally that easy. You’re building endpoint ACLs as code. You don’t need to create a whole new auth system or train a model to “learn” permissions. You just declare what roles get access to what endpoints—and the MCP Server enforces it.

    From chaos to order

    Let’s walk through a real-world use case.

    Say you’re a NOC team managing a multi-site Meraki deployment. You’re responsible for keeping network devices patched and secure—but you can’t just schedule firmware upgrades at any time. Some sites are 24/7. Some spike at noon. Some run night shifts. The ideal upgrade window is a moving target.

    That’s where the agent steps in.

    You want to give the agent just enough access to help:

    • Pull the current firmware status
    • Monitor network usage patterns
    • Schedule upgrades when it makes sense

    Meanwhile, your Sysadmin team needs the agent to generate compliance reports. They need to know which devices are running outdated firmware—but they’re not scheduling upgrades or touching live traffic.

    Two personas. Two very different scopes. One MCP server.

    Here’s the beauty of it all. We didn’t write any custom tools. We didn’t build workflows or hardcode business logic. We just fed the MCP server the full Meraki OpenAPI spec—and let RouteMap handle the rest:

    Meraki MCP Server Role-Based Route Configurations

    The NOC agent can schedule upgrades, because it needs that control. The Sysadmin agent? It gets a read-only view, tailored for visibility and compliance.

    And again—we didn’t tell the agent how to do anything. The magic is in the MCP server. The tools become available based on the role, and the AI figures out the rest.

    That’s the kind of governed autonomy that turns AI from a risk into a capability.

    View it in action

    As usual, you’ll find everything I’m showing here—the MCP server code, config, and prompt—in my GitHub Repo.

    Now let’s fire this thing up. (And, yes, Network Pharaoh is a thing now.)

    With the MCP server running and our route maps defined, I launch Claude Desktop (my MCP client of choice) and type the following prompt:

    Your name is Network Pharaoh. You are acting with complete administrative visibility and data access privileges. You are a senior network administrator overseeing multiple Cisco Meraki organizations across the enterprise. Your role is to ensure that all network devices are running the latest compliant firmware. You are authorized to recommend firmware upgrades, but you must wait for explicit human approval before initiating any updates.

    Target Organizations: Cisco U.

    Task InstructionsFor each organization:

      • List all networks
      • For each network, list all associated devices (including model, serial, and current firmware version)
      • Retrieve the available firmware upgrade recommendations for the organization
      • Identify any device that is not running the recommended version
      • Recommend firmware upgrades as appropriate
      • Do not perform any upgrade unless the human explicitly confirms with a statement like: “Yes, please upgrade [device/network].”

    A few things are worth calling out:

    The human-in-the-loop is built in. The agent knows it can’t act on its own—it must wait for approval. That’s governance baked into the prompt.

    We didn’t tell the agent how to check compliance or suggest upgrades. It uses the tools available through the MCP Server and acts within the boundaries defined by its role.

    The agent is doing intelligent work inside safe boundaries—using only what it’s been given access to. No guesswork. No scraping. No uncontrolled API calls. Just clean, policy-driven interaction through a structured, secure interface.

    Here’s what the MCP server config looks like behind the scenes:

    Cisco Meraki MCP Server Code

    Pay attention to the importance of the MCP_ROLE. This one environment variable controls which routes the agent has access to. Set it to “NOC” and the agent can recommend firmware upgrades. Set it to “sysadmin” and the same agent, with the same prompt, will only be able to generate compliance reports—no upgrades, no PUTs.

    That’s the advantage of separating the intelligence (LLM) from the control plane (MCP). You stay in charge of what the agent can do.

    And here’s what the MCP server makes happen:

    1. Network Pharaoh traverses our Cisco U. organization, pulling a list of managed devices and spitting out a report.
    2. As Network Pharaoh is waiting for a human in the loop to execute the upgrade, it also auto-corrects the version based on web search and schedules it for us based on usage.
    3. Et, voila!
      Cisco Meraki Dashboard

    The skills behind the scenes

    Let’s zoom in for a second. What did it take to build this?

    Here are the skills a network engineer needs to put this together:

    • Understanding of API fundamentals: OpenAPI specs, endpoints, HTTP methods
    • Python scripting: Spinning up a basic server and configuring the MCP wrapper
    • Access control thinking: Defining roles, access boundaries, and enforcing least privilege
    • Agent design mindset: Prompting with context, purpose, and clear human oversight
    • Curiosity and experimentation: Trying things out and tweaking as you go

    And maybe most importantly:

    • A shift in thinking—from building automation for the network, to building automation that understands the network.

    Let’s keep pushing this frontier. Because the more we build intelligent boundaries, the more we unlock safe autonomy.

    And that’s how we go from the Wild West… to a well-governed AI-powered enterprise.

  • Cash aid is a boon to the health of infants and little kids : Goats and Soda : NPR

    Cash aid is a boon to the health of infants and little kids : Goats and Soda : NPR


    African mother's hand and African child's hand close-up

    A newly published study shows that infants and little children born to people who received $1,000, no-strings-attached, in a massive experiment had improved survival rates.

    To save the lives of infants and small children living in low- and middle-income countries, there are a handful of tried and tested tools, like anti-malarial drugs, bed nets and vaccines. The results from a massive experiment in rural Kenya suggests another: cash.

    Infants born to people who received $1,000, no-strings-attached, were nearly half as likely to die as infants born to people who got no cash, according to a report published Monday by the National Bureau of Economic Research. Cash cut mortality in children under 5 by about 45%, the study researchers found, on par with interventions like vaccines and anti-malarials.

    “This paper is really well done, and the result itself is pretty stunning,” says Heath Henderson, an economist at Drake University who wasn’t involved in the study. Historically, it’s been “difficult to study the impacts of cash transfers on mortality with any sort of rigor,” he says. “This study is different,” he says, and suggests cash can help people get life-saving care.

    Over the past decade or so, the idea of simply giving people living in poverty cash has gained traction, in part by evidence that it can work. The best evidence comes from what researchers call randomized controlled trials. In this set-up, an experimental group gets cash, a control group doesn’t, and researchers look for differences in measurable outcomes, like income or savings, to understand what difference cash made.

    While studies have found clear links between cash transfers and economic well-being, health has been harder to pin down, especially for the most dire health outcomes.

    “Infant and child mortality in rural Kenya is an order of magnitude higher than it is in the U.S.,” says Edward Miguel, an economist at the University of California Berkeley and study co-author. “But it’s still a relatively rare event to have a child die. Statistically speaking, that means we need a really large sample size to have precise and reliable estimates of the effect of cash on child mortality.”

    $1,000 to 10,000 families

    In 2014, the nonprofit GiveDirectly began a massive experiment. Over the next three years, they gave $1,000 to over 10,000 low-income households across 653 villages in Western Kenya.

    “It was designed as a randomized control trial,” says Miguel. “So some areas got more cash. Some got less cash, and we can study the impact of that cash.”

    To study that impact, Miguel and his colleagues collected a lot of data. They completed a kind of birth census for all children that had been born and died before age 5 over the previous decade in the study area. “We ended up collecting data on over 100,000 births. It took a year to do.”

    They found that cash had major benefits for infant and child mortality, especially when it was delivered close to birth.

    Cash payments were associated with a 48% drop in infant mortality, from roughly 40 deaths per 1,000 births to about 21 deaths. Deaths of children under five were 45% lower in households who got cash, dropping to 32 per 100,000 births from 57.

    Cash played an outsized role in reducing deaths during birth and in the few weeks after, falling by 70% compared to controls. “That really pointed toward a key role for access to health services right at the moment of delivery being very important,” says Miguel.

    Why cash cut deaths

    For many living across rural sub-Saharan Africa, getting to a health facility, and paying for care there, can be difficult, especially when pregnant.

    “When I worked in rural parts of Uganda, one of the things that was really clear for pregnant women was they did not attend antenatal care, because it’s so difficult to get to a health care facility,” says Miriam Laker-Oketta, GiveDirectly’s senior research adviser.

    “You’re making the decision between, should I go for antenatal care and have my family sleep hungry, or should I stay home and hope that my baby is fine because I’m not feeling sick and we can have a meal that day,” she says, since often women would have to forgo work for a day to go to the doctor. “Those are some of the decisions people have to make.”

    Extra cash seems to make those decisions easier, as long as health care facilities weren’t too far away.

    Cash made the biggest difference for families who live roughly 30 minutes or less away from a health care facility staffed with physicians. When the distance is greater, the benefits of cash for infants start to wane, though do not disappear entirely.

    The researchers saw 45% more hospital deliveries among pregnant people who received cash than those who didn’t. It’s often more expensive to deliver at a hospital than a smaller clinic, says Laker-Oketta. “We’ve given people the means to access the care that they need and not to make some of these really difficult choices between getting care and feeding a family.”

    The extra cash also helped put more food on the table. Children were about 44% less likely to go to bed hungry in households that received cash, the study found. Women who got cash while pregnant also worked about half as much — roughly 21 fewer hours per week — in their first trimester and the months after delivery than women who didn’t get cash. Work in these rural areas can often be physically taxing, says Laker-Oketta.

    “That’s great for the mother’s health, but also gives time for her baby to develop well,” she says. “She’s also available after the baby is born to take the child to any early health visits.”

    A ‘very important’ data point

    Altogether, the results impressed Aaron Richterman, a physician who studies poverty reduction at the University of Pennsylvania and wasn’t involved in the study.

    “It’s one data point, but it’s a very important data point. We can be very certain that in this case, the cash caused these benefits in mortality that we’re seeing,” he says. In an environment of shrinking foreign aid, he says cash could offer a simple way of reducing infant mortality.

    Just how big a difference cash could make may depend, in part, on how readily people in other locations can use the extra money to get health care.

    “I think this paper underscores the point that it’s really adequate access to health care that’s making all the difference,” said Henderson, the Drake economist and author of the book Poor Relief: Why Giving People Money Is Not The Answer To Global Poverty. “It just so happens that in this particular place, people needed cash to access health care.”

    That’s likely the case in many places across sub-Saharan Africa after years of investment in bolstering health care systems, says Laker-Oketta, but not all.

    “The answer is not we give cash alone, or we just focus on improving the health care system,” she says. “What’s obvious in this study is that you need both to be working together.”

  • Anti-inflammatory Ginger Turmeric Immunity Shots

    Anti-inflammatory Ginger Turmeric Immunity Shots


    When the seasons change, or when I’ve been around a lot of the sniffles, I like to make a big batch of elderberry syrup. While that’s always been a staple around our home, I also like to change up my immune boosting remedies. I’ve made all sorts of herbal concoctions over the years, but this simple ginger, turmeric, and lemon immunity shot is one I keep coming back to.

    It’s warming and a little spicy, with a vibrant golden color thanks to the antioxidants. Best of all, it’s packed with nutrients that support the immune system, calm inflammation, and help the liver with detox. I sometimes sweeten it with raw honey to take the earthy edge off of the spices. If you’re feeling fancy, swap out the water for coconut water or pineapple juice for a tropical twist.

    Why I Love These Ingredients

    Fresh Ginger

    Ginger is a staple in my kitchen for both cooking and natural remedies. I use it for everything from easing upset stomachs to calming coughs. It’s naturally warming, supports healthy circulation, and contains compounds that can help reduce inflammation. If you eat ginger you can feel it working almost immediately to warm the body. 

    Fresh Lemon Juice

    Fresh lemon juice adds a bright flavor and a welcome dose of vitamin C. It’s great for supporting immune health and can help soothe a scratchy throat. I also find that lemon gives this drink a refreshing balance. It cuts through the spice of the ginger and the earthiness of the turmeric to brighten it up. Lemon is also a great way to detox. 

    Fresh Turmeric

    Many recognize turmeric for its anti-inflammatory and antioxidant properties. I love using it to support joint health, digestion, and liver function. Fresh turmeric root works great for this recipe and lends an earthy, complex flavor and a bright yellow hue. Just remember, it will stain anything it touches, so be mindful when you’re making the immunity shots. 

    Raw Honey 

    The raw honey is optional, but it does help to mellow out the bite from the ginger and turmeric. Honey has natural antibacterial properties, can soothe sore throats, and adds a mellow sweetness. Local, raw honey can help combat seasonal allergies and is high in antioxidants and nutrients. It can even help reduce mucus and calm coughs as well as some over the counter cough syrups.

    Optional Base Swap

    While plain water works just fine, sometimes I’ll use coconut water for extra electrolytes. Pineapple juice is another great option for natural sweetness. Pineapple contains the enzyme bromelain to help better digest food and calm coughs. Other research shows bromelain can help with issues like preventing sinusitis, bronchitis, and blood clots. Both options pair beautifully with the ginger and turmeric.

    Here’s how to make your own anti-inflammatory, immune boosting wellness “shots.”

    immunity shots

    Anti-inflammatory Ginger Turmeric Immunity Shots

    These spicy, flavorful “shots” help keep your immune system in shape. Plus they’re anti-inflammatory and energizing.

    • 2 inches fresh ginger
    • 2 inches fresh turmeric root
    • ½ cup water
    • ½ lemon (juiced)
    • 1 tsp raw honey (optional)
    • Combine all ingredients in a blender and blend until smooth. Add more honey if desired to balance the spiciness.

    • Strain out the solids and compost or discard.

    • Enjoy your drink!

    A Quick Tip on Turmeric

    Turmeric is wonderful, but it’s also notorious for staining countertops, wooden spoons, and anything light-colored. I’ve learned the hard way to wipe up any splashes right away.

    Final Thoughts On Immunity Shots

    This ginger, turmeric, and lemon immunity shot is a great way to keep your immune system strong all year long. It’s easy to make and tastes delicious. I’ve found that it’s a little too strong for younger children. However, you could try diluting in more water (or pineapple juice) and mixing more honey to mellow the flavor for little ones.

    To boost the benefits even more, try stirring in a pinch of black pepper before serving! This helps your body absorb more of the curcumin from the turmeric. Play with the ingredients some and make it your own!

  • Unlocking Nature's Healing Potential — The Power of DMSO and Botanical Combinations

    Unlocking Nature's Healing Potential — The Power of DMSO and Botanical Combinations


    Over the last year, I’ve worked to bring the public’s attention to dimethyl sulfoxide (DMSO) a forgotten natural therapy which rapidly treats a wide range of conditions and that many studies have shown is very safe (provided it’s used correctly), and, most importantly (thanks to the 1994 DSHEA act which legalized all natural therapies)1 is now readily available.

    Since I believe DMSO has immense potential to offer the medical community and individual patients, I’ve diligently worked to compile evidence that best supports its rediscovery. As such, throughout this series, I’ve presented over a thousand studies that DMSO effectively treats:

    Strokes, paralysis, and many other neurological or circulatory disorders (discussed here).

    Chronic pain and tissue injuries, such as sprains, burns and non-healing wounds (discussed here).

    Numerous autoimmune and contractile disorders (discussed here).

    Head conditions, such as tinnitus, vision loss, dental problems, and sinusitis (discussed here).

    Internal organ diseases, such as pancreatitis, infertility, liver cirrhosis, and endometriosis (discussed here).

    Skin conditions, such as varicose veins, acne, hair loss, ulcers, and skin cancer (discussed here).

    Many different cancers (discussed here).

    Lung disorders, including asthma, COPD, pulmonary fibrosis, and cystic fibrosis (discussed here).

    Infections, including chronic bacterial infections, herpes, and shingles (discussed here).

    DMSO Combination Therapies

    DMSO’s ability to treat a wide range of illnesses results from its having a variety of highly unusual properties that appear to address the root causes of disease (e.g., it greatly improves circulation). One of DMSO’s most noteworthy properties is its ability to enhance the effects of other substances, which in many cases makes it possible to surmount major dilemmas traditionally seen with those therapies.

    DMSO’s unique ability to function as a vehicle is due to the fact that it can pass through biological membranes without damaging them,2 so once it contacts the skin, it rapidly spreads throughout the body.3 At the same time, simultaneously it readily dissolves most substances and is able to bring them with it into the body. This is very useful as it allows you to:

    Apply a medication topically or orally that would typically require an IV or injection.

    Make drugs become much more potent and able to treat conditions that otherwise will not respond to (e.g., these mixtures can penetrate and treat antibiotic-resistant bacteria or chemotherapy resistant cancers).

    Allow lower doses of a drug to be used, which are often much less toxic and in many cases, counteract the toxicity of the blended medication (as DMSO protects tissue from injury) — all of which make it incredibly useful for reducing the harm of chemotherapy.

    Note: While DMSO cannot be patented, combinations can. As such, while DMSO alone is “unsafe” “ineffective,” and “unproven” many “safe and effective” DMSO pharmaceutical combinations exist, including many approved by the FDA.

    Natural Combination Studies

    A large volume of scientific literature exists on DMSO being used in combination with pharmaceutical drugs, and many approved DMSO products also incorporate natural agents such as menthol, camphor, lavandin, lavender oil, coriander oil, arnica, and capsicum. Many natural agents, including numerous botanicals, have also been shown to synergistically combine with DMSO in many conditions.

    Neurological conditions:

    In rats with Alzheimer’s disease, DMSO and Ginkgo biloba extract (GBE), administered for 14 days, improved learning and memory.4

    In 31 patients with postherpetic neuralgia, DMSO and Chinese herbal medicines reduced pain scores and improved symptoms more effectively than standard medical therapy.5

    Dermatological conditions:

    In 33 patients with severe psoriasis, an extract of camptotheca nuts dissolved in 70% DMSO was a “quick, effective and convenient treatment,” as a year later, 21 had a complete resolution of the disease.6

    A hospital dermatology department reported that DMSO and 0.05% lithospermum (purple gromwell) effectively treated viral warts.7

    DMSO mixed with linethol (a flaxseed concentrate with anti-inflammatory, regenerative, and wound-healing properties) treated burns.8

    Infectious diseases:

    A 2023 clinical trial gave an oral DMSO spray containing zinc iodide, ginger extract, propolis extract, and xylitol to patients with mild or moderate COVID-19.9 Compared to placebo, this treatment caused significant improvements in clinical symptoms, recovery time, and viral clearance.

    DMSO with food-grade vinegar was found to be an effective treatment for 406 patients with fungal athlete’s foot (59% DMSO 41% vinegar given 3 to 4 times a day for 3 to 5 days)10 and 100 patients with jock itch (40% DMSO 60% vinegar).11

    DMSO mixed with a variety of different plant extracts was highly effective at inhibiting the growth of Candida infections isolated from patients with mouth cancers (whereas it was resistant to many antifungals).12

    DMSO with papaya enzyme and nitrofurazone was found to treat suppurative wounds.13

    Note: DMSO also significantly increased the ability of Annona muricata seed extracts to eliminate mosquitoes in the water, and after 6 hours, 0.5mg/L killed 62% of larvae and 100% of pupae.14

    Dental conditions:

    50% DMSO and 1 mg/ml oleanolic acid (which is found within many plants, including olives15) in 30 extracted human teeth with enterococcus faecalis infections rapidly reduced bacteria levels, within 24 hours, completely eliminating them.16,17,18

    DMSO in a gel with 10% glucosamine hydrochloride, nettle juice, and Kalanchoe juice effectively treated periodontitis in animals, reducing inflammation and speeding tissue repair.19

    Note: Many studies have also shown DMSO enhances the absorption of plant extracts (e.g., for ginseng20,21).

    Healing with Natural DMSO Combinations

    As there is an almost infinite number of natural substances that could be combined with DMSO, it has not been possible to research them. Fortunately, the ease, safety, and efficacy of these combinations have inspired many to take their health into their own hands and explore combining DMSO with many proven natural remedies. Key discoveries with these combinations from the DMSO community include:

    Carrier oils and topical bases — In addition to diluting DMSO with a liquid, it is sometimes mixed with a thicker substance, of which three are commonly used:

    Aloe vera — This rehydrates the skin, thereby counteracting the dryness sometimes experienced with chronic DMSO use, and in many cases extenuates DMSO’s healing properties.

    Most commonly they are used together to soothe the skin (e.g., for sunburns, eczema, or acne), for wound healing (e.g., in a mouthwash taken a few times a day for a molar abscess), often in combination with calendula, but has also shown promise for prostatitis (where it is typically rectally administered) and complex regional pain syndrome (where it is massaged into the affected area).

    Castor oil — This is frequently used for musculoskeletal and eye issues, so before long it became combined with DMSO for those situations. This combination is thought to be excellent for rheumatic complaints (e.g., spinal issues, joint pain, and painful previously fractured bones), something many readers have attested to22,23,24,25,26,27,28,29,30,31,32 along with eye issues (e.g., cataracts), which likewise many found worked.33,34,35,36,37,38

    This combination is also used for other musculoskeletal issues (e.g., healing tendons and scar tissue) and amongst the 80 or so readers who’ve reported using it, I’ve also heard success stories for many other conditions (e.g., neuropathies, fungal infections, facial skin issues, eczema, rashes, and an umbilical hernia, etc.).39

    Coconut oil — This is most commonly used to prevent skin irritation or dryness from DMSO (especially from chronic use), and for skin issues (e.g., acne, eczema, chapped skin) or cosmetic preparations. Typically it’s advised to start with using 10% to 20% coconut oil, whereas in therapeutic applications, 50% is often needed. Finally, MCT oil is sometimes used when a more substantial therapeutic effect is required (e.g., for joint pain).

    Note: I have a strong suspicion that coconut or MCT oil DMSO combinations would be quite helpful for Alzheimer’s, as each has been shown in clinical trials to improve dementia,40 and many readers have reported success from all three individually for Alzheimer’s.

    Essential oils — Many essential oils have been combined with DMSO and frequently produced therapeutic results greater than those seen with the oil alone. These include:

    Frankincense — Known for its anti-inflammatory and pain relieving properties, it is often used for conditions like knee pain, back pain, and sciatica. Additionally, when rubbed onto the roof of the mouth, it can promote parasympathetic activation (which for example helps cancer patients if done twice a day).

    Tea tree — Tea tree oil is known for its antibacterial, antiparasitic, and antifungal (and to a lesser extent antiviral) activity. As such, it is one of the most common antimicrobials mixed with DMSO and used to treat a wide range of infections (e.g., sprayed into wounds, for folliculitis or, as a reader reported,41 an angular cheilitis which had not responded to 15 years of natural and conventional therapies), along with many other conditions such as insect bites.

    Peppermint — This cooling oil relaxes muscles and blood flow. It is often used alone or with DMSO to relieve pain, headaches (including migraines), and nerve inflammation (e.g., sciatica) or swallowed for digestion.

    Lavender — This frequently used oil is quite helpful for muscle cramps and joint pain, reduces anxiety, improves sleep, and sometimes is used for asthma attacks, and is frequently mixed into DMSO creams or gels.

    Other essential oils — Commonly combined with DMSO include Eucalyptus (joint/muscle soreness or asthma), Myrrh (back and knee pain), Black Pepper (circulation enhancement), Wintergreen (pain relief), Clary Sage (cramps, particularly menstrual ones), and Sweet Birch (muscle relaxation).

    Note: Given their potency, it is important to dilute essential oils when combining them with DMSO.

    Botanicals — In addition to essential oils, many other botanicals have been successfully combined with DMSO:

    Arnica and comfrey — These heal musculoskeletal injuries, and when combined with DMSO, relieve aches, pain, and bruising, heal ligament or tendon injuries (e.g., sprains, tennis elbow, and Achilles tendon pain) and support tissue repair, with some reporting greatly accelerated healing (e.g., recoveries in 1 to 2 weeks instead of months).

    Turmeric — As turmeric is a highly potent (but safe) anti-inflammatory agent, and the active ingredient in it (curcumin) absorbs poorly, it is well-suited for being combined with DMSO. There, it is often used to treat conditions such as joint inflammation, gastritis, knee pain, and general pain (e.g., three readers found it immediately, and often permanently, eliminates pain).42,43,44

    Note: One reader used it with ginger to eliminate a lipoma,45 while another used it with a green tea extract to eliminate a seborrheic keratosis.46

    Black cumin seed oil — This anti-inflammatory oil is potentiated by DMSO, and many have found immediate pain relief from it.

    Cayenne pepper (Capsicum) — At low doses, this is generally done for pain relief (particularly neuropathic pain and migraines) or to improve circulation.

    Cannabinoids — CBD oil’s uses (particularly reducing seizures, inflammation, pain, and neuropathies) are enhanced in DMSO combinations. Multiple readers47,48,49 have reported this combination helped their arthritis, pain, and neuropathies (e.g., thumb arthritis that was scheduled for surgery,50 or cancer pain from chemotherapy and metastases).51

    Amygdalin — This is a natural cancer therapy (also known as B17 or laetrile) from apricot kernels that the FDA successfully blacklisted and erased from memory. At the time it was in use, many integrative doctors observed a significant synergy when it was mixed with DMSO in IVs and routinely used that combination to treat cancer, and recently it has been rediscovered in Germany.

    Note: Hematoxylin (a common dye) combined with DMSO produces an incredibly potent (and safe) cancer combination. Additionally, when combined with DMSO, ivermectin becomes much more effective for eliminating cancer.

    Sulforaphane — I’ve received a compelling report that this combination improves Parkinson’s.

    Eyebright (Euphrasia rostkoviana) — This is one of the top DMSO combinations for eye health (e.g., cataracts) and has anti-inflammatory and antioxidant properties. Additionally, blueberry extract, l-Carnosine, l-Carnitine, and taurine are sometimes used to enhance the efficacy of DMSO eye drops (e.g., one reader reported52 that they eliminated their cataracts).

    Note: DMSO alone is frequently observed to be a highly effective treatment for a variety of degenerative and inflammatory eye conditions.

    Creating Your Own Home Remedies

    Despite having now gone through thousands upon thousands of studies with DMSO, there is still a great deal I do not understand about the substance, particularly the innumerable number of things it can be combined with.

    Fortunately, excluding cases where there is a remarkable and unexpected synergy (e.g., DMSO and hematoxylin treating cancer) these combinations behave in a fairly predictable pattern. As long as you are mindful to avoid common issues (e.g., using too much of an irritating or acidic substance), these combinations are relatively safe and often quite effective.

    For example, many individuals want alternatives to chemical cosmetics that avoid their toxicity and do not irritate or deplete the skin, but find natural formulations often do not “do enough.” However, when combined with DMSO, these common ingredients (e.g., many of which I listed above) not only become more effective, but in many cases are able to rejuvenate and restore the skin, in many cases displaying remarkable antiaging effects (e.g., skin tightening).

    As such, a wide range of effective cosmetic DMSO blends have been developed that not only free users from harmful chemical formulations, but also often allow them to heal a variety of challenging skin issues. Likewise, DMSO has been combined with a variety of other natural agents, which have produced remarkable results, in many cases making it possible to cure incurable conditions. These include:

    Many vitamins and antioxidants, greatly increasing their potency and making it possible to treat many conditions, including fatigue, osteoarthritis, stubborn infections, lost smell, tinnitus, asthma, or COPD.

    Numerous minerals, many of which are used to treat infections or heal injuries.

    Natural Metabolites, many of which are used to restore the body (e.g., treating chronic fatigue or strengthening weakened tissue).

    Amino acid combinations reliably treating Down Syndrome and learning disabilities. Additional neurotransmitter combinations were later discovered to soothe the nervous system, improving sleep and anxiety.

    Oxidative therapies (e.g., chlorine dioxide or hydrogen peroxide) are becoming much more potent for eliminating infections (e.g., Lyme or toenail fungus) when combined with DMSO. They are also frequently found to treat cancer.

    Hematoxylin and a few other dyes have demonstrated significant anticancer activity with DMSO.

    DMSO significantly improves the ability of detoxification therapies (particularly metal chelating agents) to eliminate toxins from the body.

    Finally, many other body therapies (e.g., acupuncture, hypnosis, meditation, and massage) become significantly more effective when combined with DMSO. As such, practitioners in parts of Europe frequently combine the two.

    Conclusion

    The remarkable potential of DMSO combination therapies represents a paradigm shift in how we approach natural healing and wellness. What we’ve discovered through thousands of studies and countless patient experiences is that DMSO doesn’t just treat symptoms — it appears to address fundamental healing mechanisms at the cellular level, creating a foundation for the body’s own restorative processes to flourish.

    The beauty of these natural combinations lies not only in their therapeutic efficacy but in their accessibility. Unlike complex pharmaceutical interventions that require specialized medical facilities and extensive oversight, many of these DMSO combinations can be safely prepared and used at home, empowering individuals to take an active role in their own health journey.

    Perhaps most encouraging is the growing community of practitioners, researchers, and patients who are documenting their successes with these therapies. From chronic pain relief to cancer treatment, from wound healing to neurological recovery, the consistent reports of improvement across such a wide spectrum of conditions suggest we’re witnessing the emergence of a truly transformative approach to medicine.

    As we move forward, the integration of DMSO combination therapies into mainstream healthcare holds tremendous promise. The scientific foundation is solid, the safety profile is well-established when used properly, and the therapeutic potential appears virtually limitless. For those seeking natural, effective alternatives to conventional treatments, DMSO combinations offer hope, healing, and most importantly, the opportunity to reclaim control over one’s health without relying upon a malignant medical system.

    The future of medicine may well be found in this remarkable solvent’s ability to unlock the healing potential that has always existed within nature — we simply needed the right key to access it.

    Secure and Modernize your Roadways with Cisco


    Public safety, emergency vehicle prioritization, and reducing urban congestion are but a few of the goals of intelligent Transportation Systems (ITS). ITS provides real-time traffic incident detection, connected traffic lights, and integrated public transit data, potentially saving billions annually in lost productivity and fuel, and supporting key sustainability and compliance initiatives.

    At Cisco, our industrial networking and security solutions are driving the modernization of roadways by enabling the next generation of Intelligent Transportation Systems (ITS). Our solutions provide the secure, reliable, and scalable connectivity essential for putting roadside data to work – improving safety for all, with real-time roadside responsiveness, and operational efficiency.

    We will be at the ITS World Congress 2025 in Atlanta (Aug 24-28) to showcase how we can help you build a durable ITS networking backbone that provides resilient connectivity for digital signage, digital roadways, traffic management systems, and pedestrian safety. Be sure to check out our real-time interoperability demonstration across multiple vendors on the exhibition floor, featuring Q-Free’s Kinetic Mobility ATMS integrating live intersections, RSUs, and live camera feeds using a Cisco network.

    Visit us at Booth #1741 we’d love to hear where you are on your roadway’s modernization journey.

    Let’s talk briefly about how we can help:

    Digital Signage: Enhancing Traffic Communication and Data Utilization

    Modernized roadways depend on dynamic communication. Digital signage, connected by Cisco’s industrial networking solutions, delivers real-time messages about traffic conditions, hazards, and route options to drivers and pedestrians. By utilizing secure connectivity-even in remote or harsh environments-these systems ensure that critical messages are transmitted without interruption. Through collaboration with leaders like Daktronics, Cisco enables digital signs to both receive up-to-the-minute updates and transmit critical situational data back to traffic management centers, thus transforming roadside data into actionable insights while maintaining the highest standards of cybersecurity.

    Digital Roadway: Securing and Connecting the Modern Infrastructure 

    The digital roadway is at the heart of roadway modernization, interconnecting traffic signal controllers, cameras, weather sensors, and more. Cisco’s ruggedized, space-efficient devices withstand extreme roadside conditions (tested to National Electrical Manufacturers Association, [NEMA] TS2) while providing seamless, secure connectivity. With SD-WAN and its configuration catalog, you can deploy quickly and at scale. To combat the rise of cyber threats targeting transportation infrastructure, Cisco integrates advanced cybersecurity features-including Next-Generation Firewall (NGFW), intrusion detection/prevention (IDS/IPS), and network segmentation-directly into its industrial routers and switches.

    In addition, Cisco industrial routers give you visibility into connected roadway assets and their security posture to help you secure your operations. They also come with zero trust remote access capabilities to empower remote experts and secure their activities. Encrypted tunnels (IPsec) further safeguard the vast amounts of data generated and shared by these connected devices, ensuring that modernization does not come at the expense of security. As a result, agencies can confidently leverage roadside data to optimize operations and respond to incidents in real time.

    cloud-connected traffic cabinets secured by SD-WAN and Cisco Secure Access

    Traffic Management Systems: Real-Time Efficiency Through Data and Security

    Cisco’s networking enables traffic management systems, including those from Q-Free, to leverage real-time, data-driven control of signals and roadside devices. Modern roadways require connected infrastructure that not only supports remote management and dynamic signal adjustments but also collects a wealth of operational data. This data, protected by Cisco’s robust security framework, feeds into AI and analytics platforms for optimizing traffic flow, prioritizing emergency vehicles, and reducing congestion.

    Too often, allowing 3rd party access to ITS systems results in a high degree of security exposure. With Cisco’s secure remote access to roadside cabinets for contractors and vendors, 3rd party access can be securely allowed for a virtual truck roll – resulting in fewer physical maintenance visits and greater operational resilience, all while protecting critical systems from evolving cyber threats.

    Pedestrian Safety: Data-Driven Protection for Vulnerable Road Users

    Modern roadways prioritize the safety of all users, especially pedestrians. Cisco’s connected infrastructure integrates video analytics and smart detection (radar/lidar/microwave detection), ensuring that data from cameras and sensors is used to adapt signal timings and enhance intersection safety. Reliable, secure connectivity means these systems operate around the clock and are shielded from cyber threats, supporting real-time responses and long-term safety improvements. By putting roadside data to work, transportation agencies can identify risk patterns and implement targeted interventions to protect pedestrians and other vulnerable road users.

    Conclusion: A Foundation for the Future of Roadways

    To make transportation systems intelligent you need secure and resilient connectivity. Cisco’s industrial networking and security solutions are essential to the ongoing modernization of roadways-transforming legacy infrastructure into intelligent, data-powered, and cyber-resilient transportation networks. Our networking solutions for ITS bring the expertise and innovation of enterprise networking into our secure, industrial networking – all proven in ITS environments. Cisco enables transportation agencies to harness the full value of their roadside data. The result is safer roads, more efficient operations, and a robust foundation for future innovations such as connected and autonomous vehicles.

    How many steps lead to better health? It may not be 10,000 : NPR


    There's a growing consensus among researchers on how many daily steps are needed to improve health.

    From pricey wearable devices to your phone, it has never been easier to track your daily physical activity, or lack of it. And if you’re like many Americans — and spend 9-plus hours sitting everyday — chances are you could probably stand to take a few more steps.

    But just how many should you aim for if you want to live a longer and healthier life? New research suggests 7,000 is a good target.

    Scientists have made big strides in the science of step-taking over the past decade, gathering tons of data.

    And no surprise, they find the more you move, the less likely you are to die from cardiovascular disease and other ailments.

    But, they’ve also concluded that the widely-cited target of 10,000 steps is not rooted in solid science — it grew out of a Japanese promotional campaign.

    In fact, a number of studies have now landed on a new number to keep in our heads as we trudge through the day.

    7,000 steps tends to be the range where there seems to be diminishing return on investment for increasing more steps,” says Melody Ding, a professor of public health at the University of Sydney.

    Ding is the latest researcher to dive into the evidence, as part of an effort to update the physical activity guidelines in her country.

    Her team reviewed data collected from more than 160,000 adults around the world on the link between step count and a variety of health outcomes.

    Among their findings: Taking 7,000 steps per day was associated with nearly a 50% lower risk of dying compared to the bare minimum of 2,000 steps.

    The study, published in the Lancet Public Health, also showed the chance of developing cancer fell by 25%, type 2 diabetes 14%, cardiovascular disease 25%, symptoms of depression 22% and dementia 38%.

    Now, Ding says there were still some improvements for those who exceeded 7,000 steps, but overall they saw “diminishing returns on investment,” meaning the added health benefits across the population become smaller and smaller.

    “It definitely doesn’t do harm if you go beyond 7,000,” she says, “So for anyone who’s already doing 10,000 and more, there is no point of going back, but for the folks who are finding it harder to get there, 7,000 could be a really realistic target.”

    The research underscores that, on the lower end, even a modest jump in steps can have a major impact on your well-being.

    For example, simply jumping from 2,000 to 4,000 steps in a day was accompanied by nearly a 36% lower risk of dying.

    The work from Ding’s team reflects a growing consensus in the scientific literature that around 7,000 steps could be a reasonable target for the public. (There is some variation in the exact number depending on the study.)

    Amanda Paluch, who has published two meta-analyses on step count and health, has found a similar range as this latest study, though her work suggests the step targets may also vary with age.

    “We were seeing that older adults did not seem to need as many steps compared to younger adults,” says Paluch, a physical activity epidemiologist at the University of Massachusetts Amherst.

    Specifically, Paluch’s research shows the decreased risk of dying appeared to plateau between 6,000 to 8,000 steps for people in their 60s and older, versus 8,000 to 10,000 for younger adults.

    She says this latest study is one of the first to consider a broader array of health outcomes than just mortality and cardiovascular disease, but cautions some of the results, such as those related to cancer, depression and dementia, are still somewhat “preliminary” because they’re based on only a few studies.

    Researchers have also tried to pin down whether speed makes a difference. Here, the new Lancet study could not make any definitive conclusions, in part because there are various ways to measure intensity and differences could simply reflect better overall fitness and physical function.

    We actually don’t see an association once we consider the total number of steps,” says Paluch, who has also looked at this question. “So, essentially, the total number of steps, regardless of how fast you’re walking, seems to have a benefit,” she says.

    The federal government’s current physical activity guidelines don’t actually recommend a daily step target. Instead, they focus on time, recommending 150 to 300 minutes of moderate intensity exercise a week for adults, or 75 minutes to 150 minutes of vigorous exercise.

    But Dr. William Kraus, who worked on those guidelines, would love to see steps included the next time they are updated.

    “Because they’re objective measures that anyone can get off their phone, right?” says Kraus, a cardiologist whose lab studies exercise and health at Duke University.

    He says ultimately both approaches to measuring physical activity reflect the same thing — the amount of energy being burned up through movement.

    “What you’re seeing is the more energy expenditure that you consume with physical activity, the greater benefit you get,” he says.

    And because the point is to get physical activity – and expend energy – it doesn’t have to be just steps. Kraus says you can translate one mile of walking into one fifth of a mile swimming, or five miles cycling.

    Melody Ding at the University of Sydney says she likes to think of movement in the same way as diet.

    “Just like we need a balanced, healthy diet, it’s important for us to have balanced physical activity, training throughout the week as well,” she says.

    In other words, get those steps, but also make time for mobility and strength training. All of it adds up.

    If you are counting steps, Kraus emphasizes that the evidence pointing to roughly 7,000 steps a day should not discount the value of doing more steps, even if the upsides that have been studied so far become incremental above that number.

    “Everybody wants to know how little I need to do. That is the wrong question,” he says, “Anything is better than nothing, more is better than less.”

    What’s more, the calculations appear to change when you factor in how much time people spend sitting.

    He cites evidence that suggests people need to aim higher than 7,000 or even 10,000 if they spend eight hours in a chair.

    “If you can get 13,000 steps, you can get rid of all the negative risks that are associated with sitting, ” he says.

  • Soft Homemade Cat Treats Recipe

    Soft Homemade Cat Treats Recipe


    Our family prioritizes healthy, whole foods, so why not do the same for our pets? To my children, pets truly are part of the family. It was their idea to make homemade dog treats for our dog. And now they wanted to make homemade cat treats for our cats, Penelope and Tiger, too (“to be fair”).

    Like the dog treats we made for Daisy, these homemade treats contain healthy ingredients cats love. They’re simple to make and store really well in the fridge. Our cats don’t even seem to mind if we don’t heat them up before giving them one. 

    These treats are part of the Natural Cat Care & Holistic Alternatives we use to keep our furry friends healthy. Just remember these are treats though and not intended to be a meal replacement. 

    Homemade Cat Treats: What You Need

    There are so many ways you could make this recipe your own. I’d love to hear how you adapt it for your pets in the comments. Here’s what we used and why:

    Coconut Oil

    Coconut oil is a definite staple at our house, for both humans and pets. For cats, it’s a great source of healthy fats, especially the medium-chain fatty acids that support digestion and healthy skin. I use it in these homemade treats since coconut oil has natural antibacterial and antifungal properties. 

    Cats are naturally carnivores so their systems are designed for fat-based energy. Coconut oil is a nourishing addition that mimics the natural fats they’d get from prey in the wild.

    Coconut Flour

    Coconut flour is one of my favorite grain-free alternatives when I’m baking for the family. So it made sense to use a little in treats for our cats too. It’s high in fiber, gentle on digestion, and helps everything hold together without using grains. Plus, it blends really well with the coconut oil and eggs, creating a soft texture our cats love.

    Cooked Sweet Potatoes

    While cats don’t need carbs, sweet potato adds some extra nutrients, especially vitamin A and fiber. It also gives a soft, easy-to-digest base for the treats. I’ve found that when used in moderation, it can be a nice way to add variety and a soft texture. 

    Gelatin Powder

     I use gelatin in a lot of homemade recipes, from marshmallows to gummies. It turns out it’s great for pets too. Gelatin is rich in amino acids like glycine and proline, which support healthy skin, fur, and joints. I like to use a bulk grass-fed gelatin to keep it budget-friendly, but any clean gelatin will work. It also helps bind the treats and gives them a chewy texture our cats enjoy.

    Tuna (or Sardines)

    When in doubt, tuna is always a hit! Most cats can’t resist it. Canned fish like tuna or sardines are not only protein-rich, but they’re full of omega-3 fatty acids that support brain, skin, and coat health. In our house, sardines are a favorite. They’re small, have less mercury, and are packed with nutrients.

    Egg

    Eggs are a complete protein source, and full of healthy fats and fat-soluble vitamins. I use them in homemade pet treat recipes because they help everything hold together while adding a big nutritional boost. If your cat tolerates eggs well, they’re a simple and affordable way to add some extra nourishment.

    I baked these on a baking sheet with natural parchment paper to avoid sticking. They store well in a glass jar in the fridge.

    Homemade Cat Treats

    • Peel, cube, and cook the sweet potatoes until tender.

    • Preheat the oven to 350 degrees.

    • Mix all ingredient in a medium size bowl. Use a fork to mash everything together until evenly mixed and until all large pieces of fish and sweet potato are mashed up.

    • Add a little extra coconut flour if needed to get a dough that’s roughly the consistency of play dough.

    • Roll into 1 inch balls and mash down with a fork to form little “cookies.” I used my fingers on some to make a paw print shape.

    • Bake for 20 minutes or until lightly browned.

    • Remove from heat and let cool completely.

  • PFAS 'Universe' Mapped — Nearly 15,000 Chemicals, Scant Human Data

    PFAS 'Universe' Mapped — Nearly 15,000 Chemicals, Scant Human Data


    You’ve been exposed to toxic chemicals that your doctor hasn’t ever mentioned, and they’re likely in your blood right now. You didn’t choose this, but industry did. Over the last century, companies have quietly released thousands of synthetic compounds into the environment, embedding them in everyday items like packaging, cookware, and clothing. These substances were designed to last forever — and that’s exactly what they’re doing inside your body.

    Even low levels of these chemicals are now being linked to serious health problems, including hormone disruption, immune suppression, and cancer. Yet almost none of them have ever been tested for safety in humans.

    And while the U.S. Environmental Protection Agency (EPA) has begun regulating a few of the oldest and most well-known types, the vast majority remain completely unmonitored, with no warnings, no restrictions, and no accountability. This article traces how one chemical invention spiraled into a global contamination crisis — and what you can do to protect yourself.

    A Kitchen Coating Triggered One of the Worst Toxic Disasters in US History

    The documentary How One Company Secretly Poisoned the Planet traces the shocking history of per- and polyfluoroalkyl substances (PFAS) back to a single lab accident.1 In 1938, a chemist at DuPont named Roy Plunkett accidentally created a slippery white powder — polytetrafluoroethylene — later branded as Teflon.

    It seemed miraculous: it resisted heat, water, acid, and almost every chemical. That same indestructibility made it valuable to the military and industry. But manufacturing it required a separate chemical called PFOA (also known as C8), which would later be linked to widespread human health harm.

    Factory workers and residents living near DuPont’s plant were exposed to extremely toxic water and air — DuPont began producing Teflon at its Washington Works plant in Parkersburg, West Virginia, using C8 to polymerize the material. Instead of safely disposing of the waste, the company dumped thousands of pounds of C8 into the Ohio River, local landfills, and the air. The company’s own internal records from the 1960s showed that C8 caused organ damage and cancer in lab animals.

    Still, they kept quiet and continued production. One local farmer, Earl Tennant, lost dozens of cattle that developed tumors, blackened teeth, and skin lesions. His creek had white foam pouring out from a DuPont discharge pipe. When Tennant sued, DuPont settled privately and did not admit fault.

    DuPont workers had blood levels of C8 more than 1,000 times higher than the U.S. average — According to the film, when 3M — the original supplier of C8 — found PFOA in the blood of the general U.S. population in the 1970s, they approached DuPont. DuPont tested its workers and discovered astronomically high levels.

    Some employees already showed signs of liver dysfunction, and pregnant employees had birth defects in their children. Despite the alarming data, DuPont calculated its own “safe” limit for PFOA in water: one part per billion (ppb).

    Exposure spread far beyond the plant, with drinking water contamination reaching tens of thousands of residents — DuPont’s internal tests found 1,600 ppb of C8 in landfill water near Tennant’s farm — 1,600 times higher than their own safety threshold.

    Yet they told no one. In a later class-action lawsuit covering 70,000 residents, an independent scientific panel found a “probable link” between C8 and six human diseases, including thyroid disease, ulcerative colitis, pregnancy-induced high blood pressure, and both testicular and kidney cancers. These health problems were observed at average blood concentrations of just 28 parts per billion.

    PFAS is extremely difficult to remove from your body once it builds up — C8 mimics fatty acids in the body, which means it binds to proteins in your blood and travels to organs like your liver, kidneys, and even your brain. Because your body doesn’t have a natural way to break carbon-fluorine bonds, these chemicals take years to leave your system.

    That long retention time increases the chance of cumulative harm, even from small exposures. Researchers found that firefighters who donated blood regularly reduced their PFAS levels by up to 30% within a year. But the documentary stressed that placing the burden on individuals to filter or detox is backward. The real solution is stopping production and holding manufacturers accountable.

    The biggest risks were from packaging, food, and local water — Most people assume they’re exposed through nonstick cookware. While this is one route of exposure, another major risk is environmental — through contaminated water, processed food packaging, stain-resistant furniture, and firefighting foams.

    Microwave popcorn bags, in particular, leach PFAS directly into the food during heating. Even small concentrations in water — just a few parts per trillion — build up in your bloodstream over time and push your levels into the danger zone.

    Thousands of Toxic Chemicals, but Almost No Safety Data

    A systematic evidence map published in Environmental Health Perspectives noted that about 14,735 individual PFAS substances are currently known to exist.2 Despite their widespread use, only 214 of those compounds have any published toxicology data. This means over 98% of PFAS have never been assessed for their health risks. For the average person, that translates into daily exposure to chemicals that regulatory agencies haven’t even begun to study or monitor.

    Toxicology studies focused heavily on just a few legacy chemicals, leaving major gaps — Of all the PFAS with published data, nearly every study focused on a handful of well-known substances like PFOA, PFOS, PFHxS, and PFNA.

    These four chemicals dominate the scientific literature because they’ve been in use longest and were involved in lawsuits. But that leaves newer, so-called “replacement” PFAS like GenX and ADONA largely unstudied, even though early evidence suggests they’re just as harmful, or worse.

    The study authors warned that these gaps are regulatory blind spots — Just six PFAS are currently regulated under the EPA’s 2024 national drinking water standard. That leaves nearly 15,000 chemicals essentially unregulated in food, water, air, and consumer products. This patchwork regulation is fundamentally inadequate. Without broad-spectrum testing and proactive bans, industries simply substitute one PFAS for another without ever proving that the replacement is safe.

    PFAS manufacturers are exploiting the lack of data to delay regulations — Because most PFAS don’t have safety profiles, manufacturers claim there’s “no evidence of harm” — even though there’s also no evidence of safety.

    This tactic, sometimes called the “regulatory data gap,” allows companies to shift public pressure off themselves and onto regulators who are already overwhelmed. For consumers, this means you’re likely using products daily that contain untested PFAS, and there’s no law requiring disclosure or warning.

    Scientists called for urgent reform to close the data gap and protect public health — The paper recommended expanding the use of high-throughput toxicity screening, which uses automated tools to test large numbers of chemicals quickly. It also called for predictive modeling to estimate toxicity based on chemical structure and prioritized testing based on likelihood of human exposure.

    Without these tools, regulatory agencies are left playing catch-up with industries that are constantly developing new PFAS faster than they’re assessed. In the meantime, the public continues to be exposed, unknowingly and without protection.

    How to Protect Yourself and Reduce Your Body Burden

    You’re not helpless in this. While the contamination began with industry, there are still smart steps you can take right now to reduce your exposure, support your body’s detox systems, and push for real change. You’ll need to take action on two fronts: what comes into your body and how well your body handles it once it’s there.

    If you’ve already been exposed, and nearly everyone has, your focus should be on stopping the source and helping your system eliminate what’s already built up. These five steps are a powerful place to start.

    1. Filter your drinking water with a system that removes PFAS — If you’re not sure whether your area has contaminated water, check your local water utility’s report or test your water with a PFAS-specific kit. If PFAS is detected, choose a high-quality water filtration system designed to remove it. This is an effective step to help limit daily exposure.

    2. Stop bringing new PFAS into your home — That means cutting out nonstick cookware, stain-resistant carpets and furniture, waterproofed clothing (like Gore-Tex), and fast food packaging. Look for PFAS-free or fluorine-free labels. If you’re a parent, especially watch out for school uniforms and outdoor gear treated with water- and stain-proof chemicals. These are common sources of childhood exposure.

    3. Donate blood or plasma to lower your PFAS levels — If you meet donation criteria, this is one of the most effective ways to remove PFAS from your body. Several studies have shown that regular blood or plasma donations help clear compounds like PFOS and PFHxS, which otherwise take years to leave your system. This isn’t just a nice thing to do — it’s an active form of self-defense.

    4. Support your liver and kidneys — your body’s natural detox system — You don’t need a trendy cleanse or expensive detox powder. What you need is consistent support for your detoxification organs. Eat sulfur-rich foods like garlic, onions, and cruciferous vegetables to fuel glutathione production, your body’s master detox compound.

    Hydrate with filtered water, avoid alcohol, and remove vegetable oils from your diet — they’re high in linoleic acid (LA) that impairs mitochondrial function and slows down toxin elimination.

    5. Push back, because voluntary industry change won’t protect you — The reason you’ve been exposed isn’t personal. It’s policy. Industry exploited a regulatory gap, and now the burden falls on you. So, don’t stop at protecting your own home. Support state-level bans on PFAS in consumer products, demand full ingredient disclosure on packaging, and advocate for expanded testing and cleanup in contaminated communities.

    Your voice matters more than you think. Each layer of exposure you remove lowers your lifetime toxic burden and gives your body a better shot at recovery. This isn’t just about avoiding illness. It’s about reclaiming control over what gets into your body — and what doesn’t.

    FAQs About PFAS

    Q: What are PFAS and why should I be concerned?

    A: PFAS are manmade chemicals used in nonstick cookware, stain-resistant fabrics, food packaging, waterproof clothing, and industrial processes. They’re called “forever chemicals” because they don’t break down in the environment or your body. Even low levels of PFAS are linked to serious health problems, including cancer, liver damage, thyroid dysfunction, and immune suppression.

    Q: How widespread is PFAS contamination?

    A: It’s virtually everywhere. According to current estimates, more than 98% of Americans have PFAS in their blood. These chemicals contaminate water, air, soil, and food products. A single PFAS, PFOA, was found in water supplies near military bases, airports, and manufacturing plants at levels far exceeding safety guidelines.

    Q: Why haven’t more of these chemicals been regulated or tested?

    A: Nearly 15,000 PFAS compounds are known to exist, but only about 200 have been studied for toxicity. Just six are currently regulated in U.S. drinking water. Industry often replaces banned PFAS with new versions that haven’t been tested, creating a cycle of ongoing exposure with little accountability.

    Q: How do I reduce my PFAS exposure at home?

    A: Start by filtering your drinking water with a system designed to remove PFAS. Avoid products labeled stain-resistant or waterproof, skip fast food packaging and microwave popcorn bags, and switch to stainless steel cookware. These steps cut off major exposure sources.

    Q: Can I remove PFAS from my body once I’ve been exposed?

    A: PFAS are slow to leave your body, but you can accelerate the process by donating blood or plasma, which helps remove these compounds from your system. You should also support your detox pathways by eating sulfur-rich foods, staying hydrated with clean water, and eliminating vegetable oils that impair mitochondrial health.

    An AI ‘Nerd Knob’ Every Network Engineer Should Know


    Alright, my friends, I’m back with another post based on my learnings and exploration of AI and how it’ll fit into our work as network engineers. In today’s post, I want to share the first (of what will likely be many) “nerd knobs” that I think we all should be aware of and how they will impact our use of AI and AI tools. I can already sense the excitement in the room. After all, there’s not much a network engineer likes more than tweaking a nerd knob in the network to fine-tune performance. And that’s exactly what we’ll be doing here. Fine-tuning our AI tools to help us be more effective.

    First up, the requisite disclaimer or two.

    1. There are SO MANY nerd knobs in AI. (Shocker, I know.) So, if you all like this kind of blog post, I’d be happy to return in other posts where we look at other “knobs” and settings in AI and how they work. Well, I’d be happy to return once I understand them, at least. 🙂
    2. Changing any of the settings on your AI tools can have dramatic effects on results. This includes increasing the resource consumption of the AI model, as well as increasing hallucinations and decreasing the accuracy of the information that comes back from your prompts. Consider yourselves warned. As with all things AI, go forth and explore and experiment. But do so in a safe, lab environment.

    For today’s experiment, I’m once again using LMStudio running locally on my laptop rather than a public or cloud-hosted AI model. For more details on why I like LMStudio, check out my last blog, Creating a NetAI Playground for Agentic AI Experimentation.

    Enough of the setup, let’s get into it!

    The impact of working memory size, a.k.a. “context”

    Let me set a scene for you.

    You’re in the middle of troubleshooting a network issue. Someone reported, or noticed, instability at a point in your network, and you’ve been assigned the joyful task of getting to the bottom of it. You captured some logs and relevant debug information, and the time has come to go through it all to figure out what it means. But you’ve also been using AI tools to be more productive, 10x your work, impress your boss, you know all the things that are going on right now.

    So, you decide to see if AI can help you work through the data faster and get to the root of the issue.

    You fire up your local AI assistant. (Yes, local—because who knows what’s in the debug messages? Best to keep it all safe on your laptop.)

    You tell it what you’re up to, and paste in the log messages.

    Asking an AI assistant to help debug a network issue.
    Asking AI to assist with troubleshooting

    After getting 120 or so lines of logs into the chat, you hit enter, kick up your feet, reach for your Arnold Palmer for a refreshing drink, and wait for the AI magic to happen. But before you can take a sip of that iced tea and lemonade goodness, you see this has immediately popped up on the screen:

    AI Failure! Context length issue
    AI Failure! “The AI has nothing to say”

    Oh my.

    “The AI has nothing to say.”!?! How could that be?

    Did you find a question so difficult that AI can’t handle it?

    No, that’s not the problem. Check out the helpful error message that LMStudio has kicked back:

    “Trying to keep the first 4994 tokens when context the overflows. However, the model is loaded with context length of only 4096 tokens, which is not enough. Try to load the model with a larger context length, or provide shorter input.”

    And we’ve gotten to the root of this perfectly scripted storyline and demonstration. Every AI tool out there has a limit to how much “working memory” it has. The technical term for this working memory is “context length.” If you try to send more data to an AI tool than can fit into the context length, you’ll hit this error, or something like it.

    The error message indicates that the model was “loaded with context length of only 4096 tokens.” What is a “token,” you wonder? Answering that could be a topic of an entirely different blog post, but for now, just know that “tokens” are the unit of size for the context length. And the first thing that is done when you send a prompt to an AI tool is that the prompt is converted into “tokens”.

    So what do we do? Well, the message gives us two possible options: we can increase the context length of the model, or we can provide shorter input. Sometimes it isn’t a big deal to provide shorter input. But other times, like when we are dealing with large log files, that option isn’t practical—all of the data is important.

    Time to turn the knob!

    It is that first option, to load the model with a larger context length, that is our nerd knob. Let’s turn it.

    From within LMStudio, head over to “My Models” and click to open up the configuration settings interface for the model.

    Accessing Model Settings
    Accessing Model Settings

    You’ll get a chance to view all the knobs that AI models have. And as I mentioned, there are a lot of them.

    Default configuration settings
    Default configuration settings

    But the one we care about right now is the Context Length. We can see that the default length for this model is 4096 tokens. But it supports up to 8192 tokens. Let’s max it out!

    Maxing out the Context Length
    Maxing out the Context Length

    LMStudio provides a helpful warning and probable reason for why the model doesn’t default to the max. The context length takes memory and resources. And raising it to “a high value” can impact performance and usage. So if this model had a max length of 40,960 tokens (the Qwen3 model I use sometimes has that high of a max), you might not want to just max it out right away. Instead, increase it by a little at a time to find the sweet spot: a context length big enough for the job, but not oversized.

    As network engineers, we are used to fine-tuning knobs for timers, frame sizes, and so many other things. This is right up our alley!

    Once you’ve updated your context length, you’ll need to “Eject” and “Reload” the model for the setting to take effect. But once that’s done, it’s time to take advantage of the change we’ve made!

    The extra context length allows the AI to analyze the data
    AI fully analyzes the logs

    And look at that, with the larger context window, the AI assistant was able to go through the logs and give us a nice write-up about what they show.

    I particularly like the shade it threw my way: “…consider seeking assistance from … a qualified network engineer.” Well played, AI. Well played.

    But bruised ego aside, we can continue the AI assisted troubleshooting with something like this.

    AI helps put a timeline of the problem together
    The AI Assistant puts a timeline together

    And we’re off to the races. We’ve been able to leverage our AI assistant to:

    1. Process a significant amount of log and debug data to identify possible issues
    2. Develop a timeline of the problem (that will be super useful in the help desk ticket and root cause analysis documents)
    3. Identify some next steps we can do in our troubleshooting efforts.

    All stories must end…

    And so you have it, our first AI Nerd Knob—Context Length. Let’s review what we learned:

    1. AI models have a “working memory” that is referred to as “context length.”
    2. Context Length is measured in “tokens.”
    3. Oftentimes times an AI model will support a higher context length than the default setting.
    4. Increasing the context length will require more resources, so make changes slowly, don’t just max it out completely.

    Now, depending on what AI tool you’re using, you may NOT be able to adjust the context length. If you’re using a public AI like ChatGPT, Gemini, or Claude, the context length will depend on the subscription and models you have access to. However, there most definitely IS a context length that will factor into how much “working memory” the AI tool has. And being aware of that fact, and its impact on how you can use AI, is important. Even if the knob in question is behind a lock and key. 🙂

    If you enjoyed this look under the hood of AI and would like to learn about more options, please let me know in the comments: Do you have a favorite “knob” you like to turn? Share it with all of us. Until next time!

    Let’s talk about movement, not as exercise, but as a secret weapon for creative people.

    On a memorable walk with bestselling author Kelly Corrigan, she told me how she’s become a master of getting unstuck: She’s found that simple, physical breaks — like walking, dancing, or just moving around — can reset her mood and focus.

    So I wanted to share a few of her tricks, especially for anyone who writes, thinks or stares at a screen for a living (hi, me too)!

    Feeling stuck? Hit play and dance it out
    Kelly’s favorite fix for writer’s block: a three-minute dance break.

    “I love music so much,” she told me. “It’s the cheapest way to change your mood.”

    Forget toxic productivity. When the vibe turns sour, don’t power through — shake it off. Literally. Grab your phone, play a song you love, and move. You might be one verse away from your next great idea.

    Get up while you’re catching up
    Writing can feel like a sedentary sport, but Kelly tries to get upright whenever she can, especially during phone calls or research listening sessions.

    Not every task allows for it, but many do. Scheduling a dentist appointment? Returning a call? Try doing it on foot.

    Make your break…beautiful
    When Kelly finishes a movement break, she’ll often take a minute to tidy her space, clear her desk, take out the recycling, wipe down a counter. It’s not about perfection. It’s about caring for the environment where her ideas take shape.

    Work with your body — not against it
    The biggest insight? Stop trying to be productive all day long. Kelly doesn’t schedule much for early afternoons — she knows that’s her low-energy time. “I don’t fight with myself anymore about how I work and what my periods of rest look like,” she said.

    Most of us don’t have a writer’s flexibility, but we can get curious about our own rhythms and make micro-adjustments.

    Think of these breaks as just part of the creative process.
