Touching your face may reveal hidden stress

Neuroscientists at Columbia and McGill have discovered that high levels of a brain chemical cause depression and suicidal thoughts in people who experienced trauma or adversity during childhood.

A team at the Technical University of Munich's TUM University Hospital has implanted a brain‐computer interface in a patient paralyzed from the neck down. The five‐hour procedure was the first of its kind performed in Europe. The device enables research that could one day help restore independence and improve quality of life for patients. In particular, the scientists hope to enable the 25‐year‐old patient to control his smartphone and a robotic arm using only his thoughts. The researchers are now seeking additional participants.

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.

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.

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.
