This Missing Vitamin Could Stop Cancer Cells in Their Tracks
Researchers at the University of Lausanne discovered that vitamin B7 (biotin) is essential for the mitochondrial enzyme pyruvate carboxylase, which lets cancer cells sidestep their usual glutamine addiction. When biotin is removed, the enzyme stalls, cutting off an alternative fuel pathway and arresting tumor cell growth. The study also shows that mutations in the cancer‑linked FBXW7 gene amplify this vulnerability by reducing pyruvate carboxylase levels, making cells more dependent on glutamine. These insights point to a dual‑target strategy that could overcome resistance to glutamine‑blocking therapies.
Scientists Say This Type of Olive Oil Could Boost Brain Power
New research from the URV, IISPV and CIBERobn, part of the PREDIMED‑Plus trial, shows that extra virgin olive oil can boost cognitive performance in older adults by reshaping the gut microbiome. Over two years, 656 overweight participants who consumed virgin...
Can Sparkling Water Boost Metabolism and Help with Weight Loss?
A brief analysis in BMJ Nutrition Prevention & Health finds that sparkling water may modestly increase glucose uptake and metabolism, but the effect is too small to drive meaningful weight loss. The author likens the CO₂‑induced alkalinity shift to processes...
Scientists Discover Natural Hormone that Reverses Obesity
Scientists at the University of Oklahoma found that the natural hormone FGF21 can reverse obesity in mice by signaling a hindbrain circuit involving the nucleus of the solitary tract, area postrema, and parabrachial nucleus. This pathway overlaps with the brain...
Scientists Remove “Zombie” Cells and Reverse Liver Damage in Mice
UCLA scientists discovered that senescent liver macrophages, marked by the p21‑TREM2 signature, accumulate with age and high cholesterol. In mice, the senolytic drug ABT‑263 selectively removed these cells, dramatically reducing liver size and body weight despite a continued unhealthy diet....
Scientists Discover Why Bread Can Cause Weight Gain without Extra Calories
A new study from Osaka Metropolitan University shows that mice will abandon standard chow for carbohydrate‑rich foods like bread, wheat and rice flour, gaining weight without increasing total calories. The weight gain was linked to a reduction in energy expenditure...
Men and Women with Obesity Face Very Different Hidden Health Risks
New research presented at the European Congress on Obesity reveals that obesity impacts men and women differently, with men showing more visceral fat accumulation, higher liver enzymes and triglycerides, while women exhibit greater inflammation and higher LDL cholesterol. The study...
Stanford Scientists Discover “Natural Ozempic” Without Side Effects
Stanford Medicine scientists have identified a naturally occurring 12‑amino‑acid peptide, dubbed BRP, that mimics the appetite‑suppressing effects of semaglutide (Ozempide) in animal models. In lean mice and minipigs, a single injection cut food intake by up to 50% and daily...
Why Ozempic Doesn’t Work for Everyone: Scientists Just Found a Hidden Reason
Researchers at Stanford Medicine and international partners identified a genetic basis for reduced effectiveness of GLP‑1 receptor agonists, such as Ozempic, in about 10% of the population. The study links specific PAM gene variants to a newly described GLP‑1 resistance,...
Two Simple Eating Habits Linked to Lower Weight, Study Finds
A longitudinal study of 7,000 Spanish adults found that extending overnight fasting and eating breakfast early are linked to lower body‑mass index over five years. The research, published in the International Journal of Behavioral Nutrition and Physical Activity, used data...
A 67-Year-Old “Crazy” Theory About Vitamin B1 Has Finally Been Proven
Researchers at UC Riverside have stabilized a highly reactive carbene in water, confirming Ronald Breslow's 1958 hypothesis that vitamin B1 can form a carbene intermediate in cells. By encasing the carbene in a protective molecular cage, the team observed it remaining...
A Common Nutrient Could Supercharge Cancer Treatment
University of Chicago researchers found that the dietary carotenoid zeaxanthin directly boosts CD8⁺ T‑cell activity, enhancing the immune system's ability to recognize and destroy cancer cells. In mouse models, dietary zeaxanthin slowed tumor growth and amplified the effects of checkpoint‑inhibitor...
Dragonflies Can See a Color Humans Can’t and It Could Change Medicine
Researchers at Osaka Metropolitan University identified a dragonfly opsin that detects light around 720 nm, extending into deep red beyond human vision. The protein’s red‑sensing mechanism is virtually identical to that of mammalian red opsins, indicating a striking case of parallel...
Scientists Discover Spice Synergy that Boosts Anti-Inflammation 100x
Researchers at Tokyo University of Science found that combining three common spice compounds—capsaicin, menthol and 1,8‑cineole—produces an anti‑inflammatory response in macrophages that is several hundred times stronger than any of the agents alone. The synergy stems from simultaneous activation of...
Your Vitamin D Levels in Midlife Could Shape Your Brain Decades Later
A 16‑year longitudinal study of 793 middle‑aged adults found that higher vitamin D levels in their 30s‑40s were associated with lower tau protein accumulation later, a biomarker linked to Alzheimer’s disease. Participants with vitamin D above 30 ng/mL showed reduced tau...
