Activating brown fat may yield a new strategy to tackle obesity

Cognitive reserve (CR) is the brain's ability to maintain cognitive function despite age-related brain changes, damage or disease. It reflects an individual's capacity to cope with these changes by utilizing pre-existing cognitive strategies or developing compensatory mechanisms.

Patients with atrial fibrillation who live in neighborhoods with poor access to full-service grocery stores face sharply higher odds of stroke and death, according to a new study from Tulane University.

Deep in the Bolivian Amazon exists a forager-horticultural community called the Tsimane. Researchers look to them for insights on how the human body functioned prior to modern technologies, as their lifestyles remain the closest to that of our ancestors.

A new UCLA Health study found that taking an eight-strain probiotic daily may reduce the risk of pouchitis, a common inflammatory condition that occurs after colon removal surgery for ulcerative colitis, but the treatment may not be worth the cost depending on a patient's likelihood of flare-ups.

The recent ouster of Centers for Disease Control and Prevention Director Susan Monarez and the resignations of top officials mark not just an institutional crisis but the latest chapter in a political war on evidence-based public health. This purge is not reform. It is the culmination of a right-wing assault that began in President Donald Trump's first term, when science was mocked, expertise sidelined and conspiracy theories elevated above epidemiology.

The U.S. Food and Drug Administration is urging nicotine pouch manufacturers to adopt child-resistant packaging to help prevent children from accidentally ingesting the pouches.

A type of brain cell that plays a vital role in maintaining neural networks and repairing injuries lies at the core of a promising new study on Alzheimer's disease from the USF Health Byrd Alzheimer's Center and Research Institute.

Two new papers from Clinical Gastroenterology and Hepatology and Gastroenterology shed light on how gut-brain interactions, influenced by both biology and life circumstances, shape eating behaviors. Together, they highlight the importance of multidisciplinary, personalized approaches to digestive health and nutrition.

As we age, what and how much we eat tends to change. However, how meal timing relates to health remains less understood. Researchers at Mass General Brigham and their collaborators studied changes to meal timing in older adults and discovered people experience gradual shifts in when they eat meals as they age.

A top health official in Florida vowed Wednesday to end all vaccine mandates in the state, including school requirements, likening the measure to prevent childhood diseases to "slavery."

Dr. Vadim Jucaud's lab at the Terasaki Institute has developed a human vascularized liver cancer-on-a-chip model to evaluate vessel remodeling and cell death in response to embolic agents. This novel platform reflects the microenvironment of liver tumors, particularly a functional and perfusable microvasculature that can be embolized. This in vitro tool aligns with the National Institutes of Health (NIH) efforts to reduce animal testing and promote alternative methods, including microfluidic devices that mimic human organs.

Colorectal cancer is unique in having its own microbial "fingerprint," according to new research from the University of East Anglia.

A new study, led by the University of Cambridge in collaboration with Bournemouth University, shows that autistic people identify loneliness, hopelessness, and feelings of worthlessness and failure as key factors underpinning their suicidal feelings. Individuals who highlighted being unable to access the support they needed were more likely to have attempted suicide. Autistic women and gender minorities were disproportionately over-represented among those who struggled to access support.

An MUSC research team reports in Cells that the complement system, part of the body's natural immune defenses, is a key driver of inflammatory responses that contribute to fetal brain inflammation and preterm birth, the latter of which is the leading cause of complications and death in newborns.

Close your eyes and visualize the following: a decadent piece of chocolate cake, a bouquet of fully bloomed red roses, a juicy peach. Hopefully, these mental images produced some form of positive feeling. But is it possible that, despite the feel-good emotions associated with all of them, our brains react differently to food-specific items?

Toddlers assessed during the COVID-19 pandemic had slightly fewer emotional and behavioral problems compared to children assessed before the pandemic, suggesting some toddlers may have shown resilience during this time. This finding comes from a study of over 3,000 children across the United States using data from the Environmental influences on Child Health Outcomes (ECHO) Cohort Consortium collected between September 2009 and July 2023.

Researchers have found that a single injection of the antibiotic benzathine penicillin G (BPG) successfully treated early syphilis just as well as the three-injection regimen used by many clinicians in the United States and elsewhere. These findings from a late-stage clinical trial suggest the second and third doses of conventional BPG therapy do not provide a health benefit.

Researchers at McMaster University have discovered that a rare but dangerous reaction to a widely used blood thinner is caused by a single antibody—overturning decades of medical misunderstanding and opening the door to more precise ways of diagnosing and treating this medical complication.
