Gut bacteria show promise as a non-invasive, low-cost screening tool for colorectal cancer

Most research suggests that opioid overdoses involving multiple substances in the United States typically occur among people aged 25–54. However, a new study led by Boston University School of Public Health (BUSPH) and Mass General Brigham for Children indicates that polysubstance-involved opioid overdoses are also prevalent among youth.

A new study at the University of North Carolina at Chapel Hill has discovered a surprising new mechanism in the brain that may explain why people recovering from drug addiction often relapse.

Scientists at the Icahn School of Medicine at Mount Sinai have developed a powerful new computational tool that could transform how cancer tissues are analyzed and help pave the way for more personalized treatments. The study, published in Nature Biomedical Engineering, introduces MARQO, a next-generation image analysis process that extracts detailed cellular and spatial information from tumor tissue slides with unprecedented accuracy and scalability.

Research into Blue Zones—regions of the world where people tend to live longer—shows that having a sense of purpose in life may help people live longer.

An estimated 50 million people worldwide have dementia, with Alzheimer's disease—accounting for more than 70%—being the representative neurodegenerative brain disorder. A Korean research team has, for the first time, identified at the molecular level that tau and amyloid-β, the two key pathological proteins of Alzheimer's disease, directly communicate to regulate toxicity.

Hundreds of children in Indonesia lined up for free measles shots Monday as authorities rolled out a vaccination campaign in response to an outbreak that has caused 17 deaths.

A person who traveled to El Salvador has been diagnosed with New World screwworm—the first reported U.S. case tied to travel to a country with a current outbreak.

A Maryland resident who traveled to El Salvador has been diagnosed with New World screwworm—the first reported U.S. case tied to travel to a country with a current outbreak.

For years, women in remote Kimberley communities faced an impossible choice—travel hundreds of kilometers for cervical screening or go without. Now, thanks to research from the University of Notre Dame Australia, that choice is being transformed.

Researchers at Karolinska Institutet, KTH Royal Institute of Technology and SciLifeLab have developed a new method for detecting early signs that the disease type 1 diabetes is going to develop. The study, conducted in an experimental model, shows that analyzing tiny amounts of blood can reveal disease-causing changes in the body, thereby enabling early treatment and disease prevention. The results have been published in the journal Diabetologia.

New research from the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) demonstrates the accuracy of modern radiotherapy techniques used to treat cancer. The study is published in the Journal of Applied Clinical Medical Physics.

A genetically modified pig lung remained viable and functional over a period of 9 days after being transplanted into a human recipient who had been declared brain dead, according to research published in Nature Medicine. These findings may represent the first documented instance of cross-species lung transplantation and have potential future clinical applications, the authors suggest.

For patients with nonambulatory type 2 or type 3 spinal muscular atrophy, apitegromab, a monoclonal antibody that inhibits myostatin activation, improves motor function versus placebo, according to a study published online Aug. 13 in the Lancet Neurology.

Only a few decades ago, it was believed that ADHD was something one outgrew during adolescence. However, about half of those diagnosed at a young age carry it into adulthood.

Overall, 29% of infants born during October 2023 to March 2024 were immunized against respiratory syncytial virus (RSV) during the 2023 to 2024 respiratory virus season, according to research published in the Aug. 21 issue of the U.S. Centers for Disease Control and Prevention Morbidity and Mortality Weekly Report.

Mississippi has declared a public health emergency after reporting its highest infant death rate in more than a decade.

Alcohol withdrawal is associated with positive changes in the composition and function of the gut microbiome, improving our understanding of the gut's influence on physiological and behavioral health, including alcohol craving, a new study suggests. The research may lead to new targets and probiotic treatments for alcohol use disorder (AUD).

A research team from the Department of Obstetrics and Gynecology at the University of Hong Kong's LKS Faculty of Medicine (HKUMed) has developed the world's first artificial intelligence (AI) model that can accurately identify human sperm with fertilization potential. This breakthrough could reshape diagnosis and assisted reproductive treatments worldwide.
