The death rate from hypertensive kidney disease (high blood pressure-related kidney disease) increased by 48% in the U.S. over the past 25 years, with continued differences across demographic groups, according to preliminary research presented at the American Heart Association's Hypertension Scientific Sessions 2025.

Breast milk is the first "super food" for many babies. Full of vitamins, minerals, and other bioactive compounds, it helps build the young immune system and is widely considered the optimal source of infant nutrition. Not all mothers, however, have the opportunity to directly breastfeed multiple times during the day and night, and might use expressed milk stored for later.

Less than half of England has access to tirzepatide (Mounjaro) through their GP, despite the NHS roll-out of the weight-loss jab officially starting over two months ago, an investigation by The BMJ has found.

Few people with high blood pressure were using salt substitutes, even though they are a simple and effective way to lower sodium intake and manage blood pressure, according to preliminary research presented at the American Heart Association's Hypertension Scientific Sessions 2025, held in Baltimore, September 4–7, 2025.

Researchers at the Icahn School of Medicine at Mount Sinai have shown for the first time that a single strand of hair can reveal unique elemental patterns that distinguish people with amyotrophic lateral sclerosis (ALS) from healthy individuals. The findings, published in eBioMedicine, suggest that a simple, noninvasive hair-based test could one day speed up ALS diagnosis and improve patient care.

A transformative new method for freezing human red blood cells has been developed by researchers from the Universities of Manchester and Leeds.

As obesity in America continues to rise at alarming rates, researchers are finding that diet and exercise are not the only driving factors. A new scientific review from UCLA Health explains how stress, hardship and other social challenges can reshape a person's gut bacteria and brain performance in ways that make it harder to keep weight off.

A study published in the Journal of Geriatric Oncology highlights a significant gap in the care of older adults with breast cancer: While many face age-related risks that could complicate treatment, a majority decline supportive services even when those risks are identified.

In the sport of sumo, a bout most commonly ends when one competitor is pushed or thrown outside of a ring of straw bales partially buried in clay.

According to research conducted by Brazilian scientists, high glucose levels may serve as a biomarker indicating a worse outcome in patients who have experienced their first acute myocardial infarction.

You may have heard of the mind-body connection: the broad concept that thoughts and feelings, especially those related to stress, can influence physical health. Mohamad Alkhouli, M.D., an interventional cardiologist at Mayo Clinic in Rochester, Minnesota, is researching the relationship between the brain and the heart. Each can have a powerful impact on the other, Dr. Alkhouli explains.

About a dozen studies in the past five years have made claims linking nearly every type of human cancer with the presence of microbiomes, "communities" of bacteria, viruses and fungi that live in or on people's bodies. Now, scientists at Johns Hopkins Medicine say a study that sequenced human cancers found far less microbial DNA sequences than earlier studies reported in the same cancer tissue samples.

A research team from Umeå University, Sweden, in collaboration with Ghent University, Belgium, has made a groundbreaking discovery about how the body's first immune defense, neutrophils, orchestrate the mobilization of zinc to fight microbes.

In many low- and middle-income countries, pediatric cardiologists can't help children with congenital heart conditions because of a critical hurdle. They don't have easy access to advanced diagnostic technology.

The brain depends on a constant supply of oxygen, delivered through an intricate network of tiny blood vessels. Unlike other organs, it has little energy stored and is particularly sensitive to interruptions in blood flow.
