COVID state of alarm declaration had significant impact on population's memory—especially the young

Brazilian researchers have taken an important step toward precision medicine by identifying four genes that can predict which melanoma patients will not respond to immunotherapy. Although this treatment has revolutionized the fight against melanoma, the most aggressive and lethal form of skin cancer, it is still costly and variable in efficacy, which limits its use, especially in the SUS (Sistema Único de Saúde), the country's national public health system. The goal is to use this finding to create ways to identify patients who are eligible for treatment, thus reducing costs in the public health system.

When school starts in West Virginia next month, 240,000 students in districts large and small will notice something missing from their cafeteria trays.

Depression is a mental health disorder characterized by a recurrent or persistent sadness and a loss of interest in activities that were previously deemed pleasurable, sometimes accompanied by changes in sleep, appetite and perceived energy levels. One of the most debilitating types of depression is major depressive disorder (MDD), which entails a pervasive low mood for a prolonged time, which in turn adversely impacts people's ability to engage in daily activities.

In a new study led by Children's Hospital of Philadelphia (CHOP), researchers found that novel eye-tracking metrics can help properly identify concussion-related vision disorders, a common phenomenon among patients with persisting post-concussive symptoms that last more than 28 days after their initial injury. The findings, recently published in the Journal of Sport and Health Science, suggest that objective infrared eye tracking could help identify which patients would benefit the most from referrals to and treatment from concussion specialists.

A current study by the German Familial Colorectal Cancer Consortium is looking at the question of which people with Lynch syndrome are at an increased risk of developing a second colorectal cancer. Researchers from the University Hospital Bonn (UKB), the University of Bonn and the University of Leipzig have now published their findings in the journal Clinical Gastroenterology and Hepatology.

A new technology that harnesses artificial intelligence (AI) to analyze mammograms and improve the accuracy of predicting a woman's personalized five-year risk of developing breast cancer has received Breakthrough Device designation from the Food and Drug Administration (FDA). Developed by researchers at Washington University School of Medicine in St. Louis, the software has been licensed to Prognosia Inc., a WashU startup company.

The phrase "summer long balls" might sound like locker-room slang, but it's increasingly being mentioned on social media and online forums as a seasonal curiosity. In hot weather, men's scrotums which contain their testicles can appear looser or more pendulous—hence the name.

In a study, patients with irritable bowel syndrome with diarrhea, or IBS-D, who went on a low FODMAP diet saw an improvement of colonic barrier dysfunction, commonly known as "leaky gut."

The microbial community in the human gut plays a central role in various diseases. An important form of chemical communication between the gut microbiome and the human body comes from small molecules produced when bacteria in the digestive system break down food. These include acids such as acetate, propionate, and butyrate. These fermentation products in the gut can regulate the immune system, promote the regeneration of the intestinal mucosa and influence human behavior. Although these effects are known, the daily dose of these molecules to which the human body is exposed was previously unknown.

Researchers led by the University of Geneva and École Polytechnique Fédérale de Lausanne report that neural anticipation of virtual infection triggers an immune response through activation of innate lymphoid cells.

Firefighters work hard saving lives, and in the process put their own lives at heightened risk from skin, kidney and other types of cancers, a new American Cancer Society (ACS) study finds.

Health officials have confirmed Wisconsin's first human case of West Nile virus in 2025.

From fetal stages through adolescence, the brain undergoes rapid, layered development—from basic motor skills to complex emotional regulation. Yet this very dynamism, coupled with children's physical and behavioral traits, makes brain imaging extraordinarily difficult. Common conditions like autism spectrum disorder (ASD), Attention-Deficit/Hyperactivity Disorder (ADHD), and perinatal brain injury often leave subtle but critical imprints on early neural architecture.

The "100 kettlebell swings a day" challenge is the latest viral fitness endeavor on social media. The challenge is simple: pick up a kettlebell and do 100 swings (bringing the kettlebell from between your legs and using your core and glutes to swing it up to chest or shoulder height) every day. These can be done either in one stint, or broken up throughout the day.

Children may be more likely to survive a rare, potentially fatal influenza complication if they receive rapid treatment for brain swelling and extreme immune responses, a Stanford Medicine-led report found.

Most U.S. adults have a "heart age" several years older than their chronological age—sometimes by more than a decade. And that gap is wider among men and among those with lower incomes or education or who identify as Black or Hispanic, according to a new study led by Northwestern Medicine.

A new study in Nature shows that delivering a single injection of gene therapy at birth may offer years-long protection against HIV, tapping into a critical window in early life that could reshape the fight against pediatric infections in high-risk regions.

A new study by investigators from Mass General Brigham examined the effects of policies banning flavored e-cigarettes on adults and young people. Investigators found that e-cigarette use significantly declined among young adults and adults in states that had enacted flavor bans relative to states that did not.
