A new study reveals that gut bacteria may play a key role in triggering ALS and frontotemporal dementia. Harmful sugars produced by these microbes can spark immune responses that damage the brain. This breakthrough explains why some genetically at .. ...

Not all parts of our genetic code are equal, even when they appear to say the same thing. Scientists have discovered that cells can detect less efficient genetic instructions and selectively silence them. A protein called DHX29 plays a key role in .. ...

Weight loss drugs and bariatric surgery may work differently, but they lead to surprisingly similar results inside the body. Both significantly reduce fat while also causing a modest loss of muscle, reshaping overall body composition. Since muscle .. ...

Chronic inflammation often works quietly in the background but can fuel serious diseases like diabetes, heart disease, and cancer. New research reveals that everyday plant compounds--like menthol from mint, cineole from eucalyptus, and capsaicin from ...

Scientists have developed a clever new way to trap "forever chemicals" in water using nano-sized cages that lock onto PFAS molecules. Unlike current methods, this approach can capture short-chain PFAS--the hardest type to remove. Tests show it can .. ...

Scientists have uncovered a surprising new player in Alzheimer's disease: a protein called CSE that helps produce tiny amounts of hydrogen sulfide gas in the brain. In experiments with genetically engineered mice, removing this protein led to memory ...

A new survey reveals a striking disconnect in how Americans think about autism research. While nearly everyone agrees that studying the autistic brain is essential, most people are unaware that brain donation after death is a key part of making that ...

Researchers have developed a cutting-edge technique that uses RNA "barcodes" to map how neurons connect, capturing thousands of links with single-synapse precision. The method transforms brain mapping into a sequencing task, making it faster and more ...

Scientists at Cornell University may be closing in on the long-sought "holy grail" of male contraception: a safe, reversible, nonhormonal method that completely halts sperm production. In a breakthrough mouse study, researchers used a compound called ...

Vitamin D levels in midlife may play a bigger role in long-term brain health than previously thought. In a study following nearly 800 people over 16 years, those with higher vitamin D levels in their 30s and 40s had lower levels of tau protein later ...
