Dementia is now the leading cause of death in Australia. But why is it fatal?

Research led by the Max Planck Institute for Biology of Aging in Cologne reports that misincorporation of ribonucleotides into mitochondrial DNA (mtDNA) initiates an inflammatory cascade.

Foreign-born immigrants to the United States have a lower risk of cardiovascular disease than their U.S.-born counterparts; however, that advantage diminishes the longer they live in the U.S., according to a study presented at the American College of Cardiology's Middle East 2025 Together with 16th Emirates Cardiac Society Conference, held October 3–5, 2025, in Dubai, UAE.

Patients undergoing coronary angiography often experience anxiety both before and during the procedure, often treated by the administration of anti-anxiety medications. A new analysis being presented at the American College of Cardiology (ACC) Middle East 2025 Together With 16th Emirates Cardiac Society Conference found virtual reality (VR) effectively reduced anxiety during the procedure and had more stable vital signs than patients receiving standard care.

Black babies died suddenly and unexpectedly in their sleep at a rate 14 times higher than white babies in Cook County between 2019 and 2023—a startling disparity revealed in a report released Wednesday by county and health officials.

Not long after California surgeon Andrew S. Hsu landed a job with a cosmetic surgery chain in Georgia, several of his patients suffered disfiguring injuries, and even his new employer had doubts about his competence, court records allege.

The health care sector is a bright spot in the economy this year, driving nearly half of the nation's employment gains, but economists and experts say immigration crackdowns and looming Medicaid cuts pose a threat to future job growth.

Young people today are growing up in an increasingly complex world—and arguably suffering as a result.

Australia's health system is one of the highest quality and most equitable in the world.

A Mount Sinai study examined how sex-based pelvic anatomical differences affect S2 alar-iliac (S2AI) screw placement and rod alignment in the coronal plane during spine surgery. It is commonly known that males have a narrower pelvis, which results in a more medial S2AI screw starting point and greater rod convergence compared to females.

It's been a tough time for sunscreens recently. Earlier this year, testing on behalf of consumer organization Choicefound several sunscreens were not delivering the sun protection you'd expect. One product claimed a sun protection factor (SPF) of 50+, but when tested had an SPF as low as 4.

In a magical scene towards the end of 2007 film "Ratatouille," notoriously harsh food critic Anton Ego is instantly transported back in time, his childhood memories revived by a spoonful of the film's eponymous dish. No pictures were needed—just the taste and scent of the food.

An AI-powered hearing test is reliably able to check your hearing on a computer or smart phone without clinical supervision, according to a study by University of Manchester researchers.

Despite research finding a higher prevalence of eating disorders among Aboriginal youth in Australia, new research from Edith Cowan University (ECU) published in the Journal of Eating Disorders has revealed a lack of culturally specific and validated screening tools or early response programs to address this issue.

Australians who use anabolic-androgenic steroids (AAS) are turning to online forums for advice on how to safely discontinue steroid-use, rather than seeking expert clinical support.

Past neuroscience studies have consistently showed the profound effects of early life experiences on the brain's wiring, particularly on the formation of the junctions that enable communication between neurons (i.e., synapses). The influence of early life experiences was found to be particularly pronounced during so-called sensitive periods (SPs), windows of time during which the brain's plasticity (i.e., its ability to form or reorganize neural connections) is heightened.

Obesity has long been acknowledged as a risk factor for a wide range of diseases, but a more precise link between obesity and Alzheimer's disease has remained a mystery—until now.

Researchers at Penn Medicine have identified specific brain circuits that are impacted by psilocybin—the active compound found in some psychedelic mushrooms—which could lead to new paths forward for pain and mental health management options.

Semaglutide or tirzepatide should be the first line treatment for people living with obesity and most of its complications, according to a new framework for the pharmacological treatment of obesity and its complications from the European Association for the Study of Obesity (EASO) published in the journal Nature Medicine.
