Eye-tracking offers measure of change in pre-clinical Alzheimer's disease

Researchers at University of California San Diego School of Medicine have discovered a previously unrecognized mechanism by which Staphylococcus aureus—one of the most common causes of skin and soft tissue infections worldwide—delays wound healing. The new study reveals that quorum sensing—a process in which bacteria communicate and coordinate behavior with one another—is a key driver of delayed healing in wounds infected by S. aureus. The findings suggest that by using drugs to interfere with quorum sensing, it could be possible to enhance wound healing without relying on antibiotics, reducing the risk of resistance and improving healing outcomes for patients.

Starting in 2026, restaurant chains in California will be required to list major food allergens on their menus in a first-of-its-kind law.

New research from The University of Texas at Arlington shows that differences in state welfare policies are linked to rising arthritis-related joint pain across much of the U.S.

Many news outlets have reported an increase—or surge—in attention-deficit/hyperactivity disorder, or ADHD, diagnoses in both children and adults. At the same time, health care providers, teachers and school systems have reported an uptick in requests for ADHD assessments.

Wildfires are no longer rare disasters in Canada. They are now an annual reality, and 2025 has already been one of the worst on record, with 3,582 fires burning 6.2 million hectares as of July 30—quadruple the 10-year average.

Researchers at UMC Utrecht have discovered that converting monoclonal antibodies from the IgG to the IgM isotype can significantly broaden their ability to recognize and bind multiple human-relevant bacterial pathogens. The study is published in Cell Reports Medicine.

Sound waves at frequencies above the threshold for human hearing are routinely used in medical care. Also known as ultrasound, these sound waves can help clinicians diagnose and monitor disease, and can also provide first glimpses of your newest family members.

Researchers from the Universitat Autònoma de Barcelona (UAB) have published an analysis that reveals new functions of the RAD21L protein—a germline-specific cohesin—crucial for male fertility. The study, carried out in mice and in collaboration with the Spanish National Research Council (CSIC), the University of Salamanca, and the National Center for Genomic Analysis (CNAG) of Barcelona, is published in the journal Science Advances.

RNA sequencing (RNA-seq) is a powerful tool in diagnosing Mendelian disorders, but the optimized sequencing depth for this technology has not yet been determined. In a new study published in the American Journal of Human Genetics, researchers at Baylor College of Medicine's Medical Genetics Multiomics Laboratory (MGML) show the utility and benefit of ultra-deep RNA sequencing in clinical diagnostics.

A new study led by USC Rossier School of Education Professor Brendesha Tynes, and published in JAMA Network Open, reveals that Black adolescents in the U.S. experience an average of six race-related online encounters every day, including three instances of online racism. These daily experiences, from algorithmic bias to traumatic event videos, are linked to increased symptoms of anxiety and depression the next day.

Mutations in a gene known as CPD play a crucial role in a rare form of congenital hearing loss, an international team of researchers has discovered.

Using fruit flies, University of Wisconsin–Madison researchers have developed a new model for investigating the genetic drivers of a rare but aggressive brain tumor in children. The work has already identified potential treatment targets for the deadly cancer that has previously had few therapeutic options.

University of Texas at Dallas researchers have developed a technology that enables same-day, 3D-printed dental restorations made of zirconia, the gold-standard material for permanent dental work.

Opening new gun stores may raise neighborhood shooting rates for years, highlighting how firearm availability affects community violence, according to Rutgers researchers.

It's nearly midnight on a school night. Your teenager's light is still on. Maybe they're finishing homework, scrolling through social media, or texting friends.

"You look so great! Have you lost weight?"

When we form a memory, brain cells need to deliver supplies to strengthen specific neural connections. A new study from MPFI and Weill Cornell Medicine has revealed how two cellular switches, Rab4 and Rab10, direct supplies to where they are needed. The findings are published in the journal eLife.
