Dec. 15, 2025 — New research shows that your brain’s “true age” can shift dramatically depending on how you live, with optimism, restorative sleep, stress management, and strong social support acting like powerful anti-aging tools. Using advanced MRI-based ...

Dec. 15, 2025 — Natural killer cells act as the immune system’s rapid-response team, but the stress of anxiety and insomnia may be quietly thinning their ranks. A study of young women in Saudi Arabia found that both conditions were linked to significantly fewer ...

Dec. 13, 2025 — Scientists exploring how the brain responds to stress discovered molecular changes that can influence behavior long after an experience ends. They also identified natural resilience systems that help protect certain individuals from harm. These ...

Dec. 13, 2025 — A new analysis suggests that people with type 2 diabetes who use GLP-1 medications like Ozempic, Trulicity or Victoza may be less likely to develop epilepsy than those taking DPP-4 inhibitors. Semaglutide showed the strongest connection to lowered ...

Dec. 11, 2025 — Rats with naturally high stress levels were far more likely to self-administer cannabis when given access. Behavioral testing showed that baseline stress hormones were the strongest predictor of cannabis-seeking behavior. Lower cognitive flexibility ...

Dec. 10, 2025 — Obesity accelerates the rise of Alzheimer’s-related blood biomarkers far more rapidly than previously recognized. Long-term imaging and plasma data show that obese individuals experience much faster increases in proteins linked to ...

Dec. 10, 2025 — A Virginia Tech study shows that ultra-processed foods may influence adolescents differently from slightly older young adults. Participants aged 18 to 21 ate more at a buffet and snacked even when not hungry after two weeks on an ultra-processed ...

Dec. 10, 2025 — New research is challenging one of medicine’s oldest assumptions: that cancer must be attacked to be cured. By treating glioblastoma patients with a simple combination of resveratrol and copper, the researchers found dramatic reductions in tumor ...

Dec. 10, 2025 — Researchers discovered that unusually high temperatures can hinder early childhood development. Children living in hotter conditions were less likely to reach key learning milestones, especially in reading and basic math skills. Those facing ...

Dec. 9, 2025 — BISC is an ultra-thin neural implant that creates a high-bandwidth wireless link between the brain and computers. Its tiny single-chip design packs tens of thousands of electrodes and supports advanced AI models for decoding movement, perception, ...

Dec. 9, 2025 — Most people worldwide aren’t getting enough omega-3, leaving a major gap between scientific recommendations and daily diets. Researchers emphasize the critical role of EPA and DHA across all life stages and point out that food alone often can’t ...

Dec. 9, 2025 — Researchers discovered that a tiny structural feature of the enzyme GPX4 helps keep neurons safe. A rare mutation removes this protection, allowing harmful molecules to damage cell membranes and trigger early dementia. Mouse and cell studies showed ...
