Scientists make microplastics glow to see what they do inside your body

Microplastics and nanoplastics are now found everywhere on Earth, from ocean depths to agricultural soils and even inside the human body. Yet scientists still struggle to understand what these particles actually do once they enter living organisms. A new study proposes an innovative fluorescence-based strategy that could allow researchers to track microplastics in real time as they move, transform, and degrade inside biological systems.

Scientists discover hidden trigger behind achilles pain and tennis elbow

A protein called HIF1 may be the missing link behind painful tendon injuries like jumper’s knee and tennis elbow. Researchers showed that high levels of HIF1 actually cause harmful changes that make tendons brittle and prone to pain. In experiments, turning the protein off protected tendons — even under heavy strain.

Scientists discover protein that rejuvenates aging brain cells

A newly identified protein may hold the key to rejuvenating aging brain cells. Researchers found that boosting DMTF1 can restore the ability of neural stem cells to regenerate, even when age-related damage has set in. Without it, these cells struggle to renew and support memory and learning. The findings raise hopes for treatments that could slow or even reverse aspects of brain aging.

This kefir and fiber combo beat omega-3 in slashing inflammation

A six-week study from the University of Nottingham suggests that pairing fermented kefir with a diverse prebiotic fiber mix may deliver a powerful anti-inflammatory boost. This “synbiotic” combination outperformed omega-3 supplements and fiber alone, leading to the broadest drop in inflammation-related proteins in healthy adults. By feeding beneficial microbes and helping them produce compounds like butyrate, the combo appeared to improve overall immune balance and metabolic health.

Scientists discover how life experiences rewrite the immune system

Why does the same virus barely faze one person while sending another to the hospital? New research shows the answer lies in a molecular record etched into our immune cells by both our genes and our life experiences. Scientists at the Salk Institute have created a detailed epigenetic map of human immune cells, revealing how inherited traits and past exposures—like infections, vaccines, or even environmental chemicals—shape immune responses in different ways.

This common tomato nutrient may help prevent severe gum disease

A large U.S. study suggests that not getting enough lycopene—the antioxidant that gives tomatoes their red color—may seriously raise the risk of severe gum disease in older adults. Researchers found that seniors with adequate lycopene intake had about one-third the risk of severe periodontitis compared with those who fell short.

A massive ADHD study reveals what actually works

A sweeping new review of ADHD treatments—drawing on more than 200 meta-analyses—cuts through years of mixed messaging and hype. To make sense of it all, researchers have launched an interactive, public website that lets people with ADHD and clinicians explore what actually works, helping them make clearer, evidence-based decisions—while also highlighting a major gap: most solid evidence only covers short-term effects, even though long-term treatment is common.

Scientists were wrong for decades about DNA knots

Scientists have discovered that DNA behaves in a surprising way when squeezed through tiny nanopores, overturning a long-held assumption in genetics research. What researchers once thought were knots causing messy electrical signals turn out to be something else entirely: twisted coils called plectonemes, formed as flowing ions inside the pore spin the DNA like a phone cord. These twists can linger and grow as DNA moves through, leaving clear electrical fingerprints.

Ancient Chinese medicine may hold the key to hair regrowth

A centuries-old Chinese medicinal root is getting new scientific attention as a potential game-changer for common hair loss. Polygonum multiflorum, long believed to restore dark, healthy hair, appears to work on multiple fronts at once—blocking hair-shrinking hormones, protecting follicles from damage, activating natural regrowth signals, and boosting blood flow to the scalp.

Scientists turn sunflower oil waste into a powerful bread upgrade

Researchers have found a surprising way to turn sunflower oil waste into a powerful bread upgrade. By replacing part of wheat flour with partially defatted sunflower seed flour, breads became dramatically richer in protein, fiber, and antioxidants—while also offering potential benefits for blood sugar and fat digestion.
