Jan. 5, 2026 — A large study has revealed that dozens of widely used chemicals can damage beneficial gut bacteria. Many of these substances, found in pesticides and everyday industrial products, were never thought to affect living organisms at all. When gut ...

Jan. 5, 2026 — A new CRISPR breakthrough shows scientists can turn genes back on without cutting DNA, by removing chemical tags that act like molecular anchors. The work confirms these tags actively silence genes, settling a long-running scientific debate. This ...

Jan. 5, 2026 — Researchers have developed experimental compounds that make cells burn more calories by subtly tweaking how mitochondria produce energy. Older versions of these chemicals were once used for weight loss—but were banned for being deadly. The new ...

Jan. 4, 2026 — Researchers compared a traditional Chinese medicine, Yueju Pill, with a standard antidepressant and found both reduced depression symptoms. However, only Yueju Pill increased a brain-supporting protein associated with mood improvement. Brain imaging ...

Jan. 4, 2026 — Not all microbes are villains—many are vital to keeping us healthy. Researchers have created a world-first database that tracks beneficial bacteria and natural compounds linked to immune strength, stress reduction, and resilience. The findings ...

Jan. 4, 2026 — A groundbreaking study shows that breast cancer screening works better when it’s personalized. Instead of annual mammograms for all, women were screened based on genetics, health history, and lifestyle factors. This approach reduced advanced ...

Jan. 4, 2026 — UK experts are warning that access to new weight-loss drugs could depend more on wealth than medical need. Strict NHS criteria mean only a limited number of patients will receive Mounjaro, while many others must pay privately. Researchers say this ...

Jan. 4, 2026 — Type 2 diabetes doesn’t just raise the risk of heart disease—it physically reshapes the heart itself. Researchers studying donated human hearts found that diabetes disrupts how heart cells produce energy, weakens the muscle’s structure, and ...

Jan. 3, 2026 — Researchers have discovered a way to help aging intestines heal themselves using CAR T-cell therapy. By targeting senescent cells that build up over time, the treatment boosted gut regeneration, reduced inflammation, and improved nutrient absorption ...

Jan. 3, 2026 — Your daily rhythm may matter more for brain health than previously thought. Older adults with weaker, more disrupted activity patterns were far more likely to develop dementia than those with steady routines. A later daily energy peak was also ...

Jan. 3, 2026 — Time-restricted eating has been widely promoted as a simple way to boost metabolic health, but new research paints a more complicated picture. When calorie intake stayed the same, an eight-hour ...

Jan. 3, 2026 — As spinal cord injuries increasingly affect older adults, new research reveals a surprising pattern in recovery. The study shows that aging does not appear to slow the healing of nerves themselves, with older patients regaining strength and ...
