Omega-3 fatty acids, popularly believed to reduce inflammation in the body, appear to increase certain inflammatory markers, researchers have found.

A crucial link between the brain's cleaning system and deterioration of neurons associated with Alzheimer's disease has been discovered by University of Queensland researchers.

A narrative review in The Journal of Nutrition suggests that whole-food plant diets may help prevent or improve erectile dysfunction (ED) by supporting vascular health and reducing risk factors such as LDL cholesterol and inflammation. However, most evidence is observational, and more clinical trials are needed.

Major cuts to Medicaid funding could have rural communities across the country facing widespread hospital closures and reduced access to health care, says Michael Shepherd, a health policy researcher at the University of Michigan.

A major systematic review and meta-analysis found that aspartame has little to no effect on blood glucose, insulin, or appetite-regulating hormones in humans. Evidence certainty is very low, with no significant long-term metabolic impact identified.

Insect-based foods face major barriers, including taste, cost, and cultural acceptance, that limit their potential to replace meat in Western diets. The review finds that plant-based alternatives remain more promising for reducing environmental impacts.

Researchers have demonstrated that E. coli can perform a biocompatible Lossen rearrangement, enabling phosphate-catalysed conversion of synthetic substrates into valuable compounds. This approach allows engineered bacteria to upcycle PET plastic waste into paracetamol, highlighting a novel intersection of chemistry and biotechnology.

Using stem cells from patients with ALS (amyotrophic lateral sclerosis), Cedars-Sinai has created a lifelike model of the mysterious and fatal disease that could help identify a cause of the illness as well as effective treatments.

For the first time in the world, a Korean research team discovered how cellular aging can spread systemically through the bloodstream-offering new insights and a potential therapeutic strategy to combat aging-related decline.

Imagine Spartan Stadium packed with 75,000 fans, all wearing green and white jerseys - except one person in a solid green shirt.

Researchers found that once-monthly maridebart cafraglutide led to substantial weight loss and improved glycemic control in adults with obesity, with or without diabetes, in a phase 2 randomized trial. The drug demonstrated an acceptable safety profile and supports further study in phase 3 trials.

Music improves mood and memory to such an extent that treatment strategies for diseases like Alzheimer's or dementia sometimes incorporate music.

Researchers are studying how new laws in Louisiana and Texas that restrict adolescent social media use and targeted food advertising impact teens’ exposure to junk food marketing. The protocol uses real-time screen recording and surveys to measure the effects on health equity.

Adolescent diets high in fat and sugar disrupt the development of the prefrontal cortex and hippocampus, impacting cognition, memory, and impulse control. These brain changes can promote unhealthy eating behaviors and obesity risk that persist into adulthood.

Little is known about what causes ovarian cancer, and there is no way to detect it early yet. About 75% of the time when someone is diagnosed with ovarian cancer, it has already progressed to stage 3 or stage 4, which means it has spread to other parts of the body.

Teens who see social media posts showing cannabis or e-cigarettes, including from friends and influencers, are more likely to later start using those substances or to report using them in the past month, according to surveys done by researchers at the Keck School of Medicine of USC.

A new research paper was published in Aging (Aging-US) Volume 17, Issue 5, on May 20, 2025, titled "Short-term moderate caloric restriction in the rhesus macaque attenuates markers of ovarian aging in select populations."

Stress does no one - not even your insulin-producing cells - any good.

Newborn babies and patients with Alzheimer's disease share an unexpected biological trait: elevated levels of a well-known biomarker for Alzheimer's.

A recent study published in Engineering has shed light on a novel combination therapy for rheumatoid arthritis (RA) that significantly reduces bone destruction by targeting the m6A methylation pathway.
