An explosion does not need to strike the head to injure the brain. When a blast occurs, it generates a sudden pressure wave that can pass through the body and skull in milliseconds, potentially deforming brain tissue and blood vessels along the way.

Monitoring and treating heart failure (HF) is a challenging condition at any age. Several models, such as Atrial fibrillation, Hemoglobin, Elderly, Abnormal renal parameters, Diabetes mellitus (AHEAD), and BIOlogy Study to TAilored Treatment in Chronic Heart Failure (BIOSTAT) compact, have been developed to predict the likelihood of a patient's survival based on clinical factors such as arrhythmia, anemia, age, diabetes, and ejection fraction.

Deep in the folds of the intestine, in microscopic pockets called crypts, a quiet surveillance system is always at work. Stem cells lining the gut wall are not just rebuilding tissue—they are listening and signaling. When certain strains of Escherichia coli brush past, these cells can sense a telltale molecular signature: flagellin, the protein that powers a bacterium's whip-like tail. That signal sets off a chain reaction, summoning immune cells that repair damage and help restore the gut's protective barrier.

The federal government's message in its new Dietary Guidelines for Americans, released in January 2026, couldn't be simpler: "Eat real food."

Your thyroid is a small, butterfly-shaped gland in the front of your neck. Its main job is to produce thyroid hormones, which help regulate your body's metabolism and control your heart rate, body temperature, growth and development. A thyroid nodule is a small bump or growth that develops on this gland. Thyroid nodules can cause a range of symptoms—or none at all.

Fred Hutch Cancer Center scientists reached a crucial milestone in blocking Epstein Barr virus (EBV), a pathogen estimated to infect 95% of the global population that is linked to multiple types of cancer, neurodegenerative diseases and other chronic health conditions. Using mice with human antibody genes, the research team developed new genetically human monoclonal antibodies that prevent two key antigens on the surface of the virus from binding to and entering human immune cells.

Anti-abortion laws are associated with more deaths among expecting and new mothers, a new study says.

Most bacterial gastrointestinal illnesses in Australia are thought to be caused by two pathogens, Campylobacter and Salmonella. But an emerging pathogen, Aeromonas, is much more common than previously thought, with UNSW researchers revealing that more than two years ago it was the second-most common bacterial intestinal pathogen in Australia.

Periods of prolonged social isolation have long been associated with difficult emotions and, in some cases, with the emergence of psychiatric symptoms, such as depression, anxiety, and difficulties connecting with others. Some past psychology studies have suggested that chronic isolation during adolescence, the critical stage between childhood and adulthood, can disrupt the structure and functioning of a brain region known as the prefrontal cortex (PFC).

Child vaccination has been one of Australia's biggest success stories. Before the COVID pandemic, we hit the national target of 95% of one-year-olds fully vaccinated. Our child vaccination rates were among the best in the world.
