Tuna recalled in seven states over listeria fears

A new study shows that the human gut microbiota can pinpoint whether an adult lives in Wuhan or Shiyan, two cities 500 km apart in China's Hubei Province, with 94% accuracy. This microbial signature is strongly linked to each city's characteristic diet.

Low doses of the injectable weight-loss medication semaglutide may improve symptoms of a hard-to-treat type of heart failure. This effect happened through direct action on the heart muscle and blood vessels, despite resulting in no significant weight loss, according to preliminary research presented at the American Heart Association's Basic Cardiovascular Sciences Scientific Sessions (BCVS 2025). The meeting, held in Baltimore, July 23–26, 2025, offers the latest research on innovations and discovery in cardiovascular science.

It is impossible to imagine life without the smartwatch for a huge group of people. About 455 million consumers worldwide used a smartwatch in 2024. They are especially popular among young adults (18–34 years old); in this age group, about 40% use a smartwatch.

A team of Memorial Sloan Kettering Cancer Center (MSK) researchers have made an important finding about why genetically engineered immune cells sometimes fail to finish the job when given as a cancer treatment. The new discovery sheds light on the tendency of these modified cells to lose power or even self-destruct before fully destroying a tumor. This is a major problem, for example, in chimeric antigen receptor (CAR) T cell therapy.

Drawing on a landmark 25-year study that followed Quebec children into adulthood, McGill University researchers have identified two distinct patterns in how suicidal thoughts emerge and the early signs that are often missed.

Restrictive practices in mental health settings—such as physical restraint and seclusion—are meant to be a last resort, used only when patients pose a risk to themselves or others.

On hot summer days, few things are more refreshing than a dip in the pool. But have you ever wondered if the pool is as clean as that crystal blue water appears?

A new study has explored how people with hereditary cancer identify on TikTok.

A multidisciplinary prehabilitation protocol shows promise in reversing frailty and improving outcomes for patients with advanced heart failure who are waiting for surgery.

A new study published in Nanotechnology offers new hope for less harmful breast cancer therapy by combining two powerful, non-invasive cancer treatments.

In a breakthrough that reimagines the way the gut and brain communicate, researchers have uncovered what they call a "neurobiotic sense," a newly identified system that lets the brain respond in real time to signals from microbes living in our gut.

In a new study, Northwestern University neurobiologists have found that the brain's internal GPS changes each time we navigate a familiar, static environment.

Completed in 2003, the Human Genome Project gave us the first sequence of the human genome, albeit based on DNA from a small handful of people. Building upon its success, the 1000 Genomes Project was conceived in 2007. The project began with the ambitious aim of sequencing 1,000 human genomes and exceeded it, publishing results gleaned from over 2,500 individuals of varying ancestries in 2015.

While current treatments for schizophrenia—a mental illness affecting 1% of the world's population—can reduce certain symptoms, they have little effect on the cognitive deficits affecting the daily life of patients.

A new study has revealed that autoantibodies—immune proteins traditionally associated with autoimmune disease—may profoundly influence how cancer patients respond to immunotherapy.

Researchers at Children's Hospital Los Angeles have discovered a key difference between the two main types of rhabdomyosarcoma—paving the way for more targeted treatments.

As plans for missions to Mars accelerate, so do questions about how the human body might cope. A return trip to the red planet would give more than enough time for someone to become pregnant and even give birth. But could a pregnancy be conceived and carried safely in space? And what would happen to a baby born far from Earth?

Whether it's your first or fourth cold of the season, many Australians are waking up at the moment with a sniffle, a sore throat or feeling more tired than usual.
