Higher deuterium in drinking water correlates with higher rates of major depression. Higher deuterium in drinking water correlates with higher rates of type 2 diabetes. This isn't a fringe hypothesis. It's a University of Utah population study mapping deuterium concentration in US tap water against disease prevalence across the country. Correlation — not proof of causation. But striking enough that Tatyana Strekalova — Clinician Scientist at Maastricht University, Senior Researcher at the University of Oxford, and Professor of Physiology at Sechenov First Moscow State Medical University — decided to test it in mice. The logic is straightforward. Deuterium concentration in drinking water decreases with distance from the ocean — inland, high-altitude water is naturally more deuterium-depleted. If geography determines deuterium load, and deuterium load correlates with disease prevalence, then what happens when you deliberately give animals water at the low end of that natural range? What her lab found is striking. They used 90 ppm deuterium-depleted water throughout — the lowest deuterium concentration found naturally in drinking water on Earth. Not a pharmaceutical dose. Not exotic laboratory depletion. And compared it to control mice drinking 140 ppm water. The difference between antarctic meltwater and coastal tap water. Finding 1: Aged mice. Two weeks. Depressive-like behaviors measurably reduced They took 18-month-old mice — equivalent to very old age, approaching maximum mouse lifespan. These mice displayed measurable depressive behaviors: Anhedonia — loss of sensitivity to reward, measured by reduced preference for sweet water. Increased helplessness behavior. Reduced novelty exploration. Impaired hippocampus-dependent memory. After two weeks on 90 ppm DDW? Sucrose preference increased — anhedonia reversed. Helplessness behavior significantly reduced. Novelty exploration improved. Hippocampal memory improved. Two weeks. Naturally occurring low-deuterium water. Measurable reversal across four independent behavioral markers. Finding 2: DDW matched antidepressant effect in stressed young mice They used a chronic stress model in young mice — predator scent, restraint stress, tail suspension. This reliably induces anhedonia in susceptible mice. Then they divided mice into three groups: normal water at 140 ppm, DDW at 90 ppm, and citalopram — a standard SSRI antidepressant. DDW produced rescue of sucrose preference comparable to citalopram. Helplessness behavior was also rescued comparably. Serotonin transporter expression — one of the key molecular targets of SSRIs — was rescued by both citalopram and DDW. This is mouse data. Direct translation to humans requires clinical trials. But the mechanism convergence is a legitimate finding. Finding 3: DDW normalized REM sleep in stressed mice Depression is the only psychiatric disorder diagnosable by a specific sleep architecture change — increased REM sleep. It's a biological marker, not a subjective report. Stressed mice showed increased REM sleep — the biological depression signature. DDW normalized REM sleep. Slow-wave sleep and wakefulness also improved. Finding 4: DDW protected against western diet-induced cognitive impairment and glucose dysregulation They used 12-month-old female mice on a standardized western diet — high saturated fat, high sugar, high cholesterol. Western diet produced: impaired glucose tolerance, brain inflammation, reduced mitochondrial markers in brain and liver, liver steatosis — fat accumulation in the liver — impaired object recognition memory, and impaired hippocampal memory. DDW at 90 ppm on western diet: Prevented glucose tolerance impairment despite continued western diet. Improved object recognition memory. Improved hippocampal memory in old mice. Did not improve liver steatosis. The liver finding matters. DDW protected the brain and metabolic glucose handling but did not reverse the liver damage. Strekalova’s interpretation: DDW is counteracting brain inflammation driven by damage elsewhere in the body — not fixing the damage itself. Finding 5: Deuterium-enriched water (180 ppm) did the opposite They tested the reverse — 180 ppm water, equivalent to what you would find in evaporative pools in the Sahara. Results on aged mice with western diet: Novelty exploration clearly suppressed. Hippocampus-dependent memory suppressed. Strekalova describes this as a surprise finding. 90 ppm sits at the low end of natural drinking water on Earth. 180 ppm sits at the high end of what occurs in extreme arid environments. The difference between them produced measurable opposing effects on memory and cognition in aged mice. Gene expression — deuterium sits upstream of circadian biology In both the aging model and the stress model, DDW altered gene expression in the hippocampus and prefrontal cortex. Affected categories: DNA repair, oxidative stress response, immune regulation, mitochondrial function, cellular plasticity, aging-related genes. And one finding that connects directly to everything else: Per2. Per2 is a core circadian clock gene. DDW affecting its expression means deuterium content influences circadian biology at the gene level. Deuterium doesn't just affect cancer cells and mitochondrial efficiency. It sits upstream of the circadian system. The implication The deuterium content of your water varies by geography. Antarctic water versus coastal tap water. The difference is measurable. The biological effects in these models are measurable and opposing. Most people optimizing their health are tracking sleep, sunlight, training, and nutrition. Nobody told them deuterium was also on the list.

There is now converging evidence in animals and humans that omega-3 fatty acids are at the least anti-catabolic and, likely, anabolic. They seem to do this by shifting the balance away from breakdown and more towards muscle building, particularly in the context of anabolic resistance. Animal studies show omega-3 fatty acids augment muscle development: Steers fed omega-3s showed improved amino acid efficiency and activated pathways involved in muscle growth. Similarly, pigs given a high omega-3 diet exhibited larger muscles and markers of improved amino acid absorption and use. But more importantly, we have human evidence: • In one study, young women taking 5 grams of omega-3s per day cut their muscle loss almost in half and increased muscle protein synthesis after two weeks of leg immobilization. • In another study, older adults consuming 3.36 grams of omega-3s daily for two months had an increase in muscle protein synthesis in the presence of amino acids and insulin. • Yet another study found that healthy older adults taking 4 grams of omega-3s daily for half a year increased various measures of muscle size and strength. • Still another study, older adults who consumed 4 grams of krill oil daily for six months improved knee strength, grip strength, thigh muscle thickness, and measures of muscle nerve response. There are still open questions. For example, a consistent theme is that many of the studies are high dose at 4 and 5 grams per day - does that imply that these effects in muscle only happen at high dosages? Another question we might ask is, in what context is omega-3 more anabolic - for example, in old age? During immobilization? When protein intake is sub-optimal for muscle building? (It often is for many of us.) Listen to my recent podcast guest Dr. Chris McGlory for more discussion of this fascinating new emerging field. Show notes and transcript for this episode here:

Abdominal wall pain: differential diagnosis A 28-year-old soccer player presented with right periumbilical pain of 2 months' duration. An MRI was performed, which showed no abnormalities in the abdominal wall. He was diagnosed with anterior cutaneous nerve entrapment syndrome (ACNES), and perineural injection was performed, with no improvement in symptoms. He came to the clinic for a second opinion, presenting with tenderness on palpation of the middle third of the rectus abdominis muscle, which increased with trunk resistance flexion. The pain decreased after this test was performed after muscle inhibition. An ultrasound assessment was completed, revealing no abnormalities in the discomfort, but evidence of increased thickness and decreased echogenicity of the tendon at its origin in the pubic ramus, associated with significant pain on sonopalpation, related to tendinosis. An evaluation was completed with a thoracic spine examination, revealing significant pain at the level of the spinous process of T8 (the rectus abdominis muscle is innervated by the T7-T12 thoracoabdominal nerves). It was decided to treat the patient with ultrasound-guided injections around the rectus abdominis tendon with 1 cc of triamcinolone and 1 cc of 2% lidocaine, and periradicular injections of the right T8 muscle with 2 cc of betamethasone and 1 cc of 2% lidocaine. The symptoms resolved immediately, and the patient did not reappear during the following two months of follow-up.

Congrats to EloShapes.com on their launch! On a similar note, is out of beta and available to the public. A lot of you have been asking me what my plan is now that EloShapes is also doing 3D scans... the answer is: nothing changed! I think that competition is good. I'm a mouse nerd and a LONG TIME EloShapes user, so the more options I get as a user, the better. I really think that my vision and EloShapes, though, is fundamentally different. I've had the domain for FMM for years, I have a much larger platform in mind compared to what I built so far. The 3D scans are the necessary step for my vision, not the end goal: they never were. I am also very proud of the fact that I've been able to scan at least 5 mice in full color EVERY DAY with my own pipeline, and I think I will easily have almost full coverage of the mice people would want on the website within months. Check the video for the mice I've added in just the last few days, all textured. Apart from some of the features I've mentioned before (like the virtual hand/grip), FMM is meant to be kind of a "MyAnimeList" for mice, so that you can share your profile, like this: and then later on leverage this curated list of mice you build for yourself to be shown even more mice you might like. FMM is also a tool for reviewers and anyone that wants to share their opinions on mice. Links like this: allow you to easily share your specific points about a mouse via the annotations, viewpoint sharing and measurements. And of course, as I've said since the beginning, I will use FMM to centralize all my hard testing about sensors, dpi, and such, so that you'll be able to find EVERYTHING about a mouse, including the raw results of my standardized sensor implementation testing. So, with this said, I will keep scanning as many mice as possible and adding as many features as possible until FMM becomes what I envisioned so long ago. Join my discord if you want to keep up! I hope you'll all give it a try! Ciao!
