Bacterial communication delays wound healing by disrupting skin cell repair

Multiple sclerosis, which affects around one in 500 people in Switzerland, is an autoimmune disease in which immune cells attack the central nervous system, causing irreversible damage. Current treatments involve blocking the immune system to prevent it from attacking the body. Although effective, these drugs can trigger potentially serious infections.

After a 20-year absence, there were 10 cases of locally transmitted malaria in the United States in 2023, according to a study published online Oct. 6 in JAMA Network Open.

Our new study highlights a crucial, but often hidden, aspect of child health—the mental health impact of living with two or more neurodevelopmental conditions.

Previous studies have reported that a high consumption of ultra-processed foods is associated with an increased risk of developing cardiovascular diseases, while other studies have shown that a diet including a large proportion of plant-based products—when nutritionally balanced—may reduce the risk of developing these diseases.

Uncontrolled bleeding during surgery remains one of the deadliest medical emergencies. Injuries to internal organs such as the liver or spleen are especially dangerous because bleeding is difficult to control and often life-threatening.

The risk for overactive bladder (OAB) is associated with both short and long sleep duration, according to a study published online Sept. 17 in Frontiers in Medicine.

A research team led by IGTP, in collaboration with IR Sant Pau and ISGlobal, identifies a protein as a central element in long COVID and highlights differences according to sex and hormonal status.

Spontaneous facial self-touching may be an evolutionary, self-soothing behavior that helps regulate stress, according to researchers from the University of Houston and Virginia Tech.

The U.S. Food and Drug Administration (FDA) has cleared another blood test that could help doctors identify whether a patient's memory problems are likely caused by Alzheimer's disease.

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.

The effectiveness of eye-tracking technology in identifying people who have a genetic tendency to Alzheimer's disease, years before their symptoms show, has been highlighted in new research.
