Adrenaline receptor helps set daily rhythm for T cell infection response, study finds

A team of researchers at the Icahn School of Medicine at Mount Sinai has developed a new method to identify and reduce biases in datasets used to train machine-learning algorithms—addressing a critical issue that can affect diagnostic accuracy and treatment decisions.

Engineers at Duke University have developed a wireless patch that can noninvasively measure skin and tissue stiffness at depths of up to a couple of inches. Already smaller than a smartwatch, the device could be a gateway into a wide array of medical applications such as the monitoring of wound healing, chronic conditions like skin cancer, fluid management during resuscitation efforts and muscle rehabilitation.

Glioblastomas are the deadliest form of malignant brain tumor, and most patients diagnosed with the disease live only one or two years. In these tumors, normal cells in the brain become aggressive, growing rapidly and invading the surrounding tissue. The resulting cancer cells are metabolically different from their neighboring healthy cells.

Over 60% of us will suffer from lower back pain at some point in our lives. Without question, it's the leading cause of disability across the globe.

There were 45,000 fewer hours of physical education (PE) delivered in UK schools during the last academic year compared to 15 years ago. This is concerning, given how important PE and physical activity are not only for children's physical health, but their cognitive health too. As the new school year begins, it's essential that PE hours in UK schools aren't further cut given its importance for academic success.

Hydrogels—materials like gelatin that can absorb and hold water—can aid wound healing and enable slow-release drug delivery, but they usually break down in acidic environments like the stomach.

Many of us are guilty of scrolling our smartphones on the toilet. But a new study from the United States, published today, has found this habit may increase your risk of developing hemorrhoids by up to 46%.

Many pregnant women are unsure if it's safe to use marijuana or products containing cannabidiol, an active compound in marijuana, even as they increasingly turn to them to combat morning sickness, anxiety or insomnia, a recent University of Florida Health study shows.

From Case Western Reserve University School of Medicine and Cleveland Clinic, investigators report that depot medroxyprogesterone acetate use was associated with a higher relative risk of meningioma brain tumor diagnosis in US women, with risk concentrated after more than four years of exposure or initiation at older than 31 years.

We consider humans to be at the apex of social cognition. But we're not the only animals that closely interact with each other. Marmosets, for example, are highly social creatures. In the wild, they choose to work together, sharing food and helping each other raise young.

The start of the fall semester and college football season can also kick off rising substance use and the harms that come with it for many young people.

A UK-wide research team, led by the University of Oxford's Nuffield Department of Surgical Sciences, has launched a major international study to improve surgical treatment for people suffering from gastroesophageal reflux disease (GERD), a chronic condition that affects around one in five adults in the UK.

Fitness and lifestyle influencers are spotlighting a new trend among middle-aged women: weighted vests. While many advocate for their use as a quicker way to burn calories, build muscle and improve bone density, the science behind the workout fad says otherwise.

People diagnosed with multiple myeloma—one of the most common forms of blood cancer—are now living nearly twice as long on average as they were in 2005, according to a new study.

Cannabis use by mothers during pregnancy and while nursing may disrupt and slow the reproductive development of their daughters and even granddaughters, a new Washington State University study suggests.

A minimalist approach to transcatheter aortic valve implantation (TAVI), without sedation, was noninferior to the standard approach for the primary outcome at 30 days, according to late-breaking research presented in a Hot Line session today at ESC Congress 2025.
