A night without sleep produced increased markers of connections between brain cells, showing that sleep in humans may be important for restoring cellular balance in the brain, according to a study published June 23rd in the open access journal PLOS Biology by David Elmenhorst from the Forschungszentrum Jülich Institute of Neuroscience and Medicine in North Rhine-Westphalia, Germany, and colleagues.

Using artificial intelligence (AI), researchers found that image-based risk scores for breast cancer derived from screening mammograms evolve over time and differ between women who develop cancer and those who do not, opening the door to a new era of dynamic breast cancer risk assessment.

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the digestive tract, with KIT mutations driving approximately 75% to 80% of cases.

A plant- and fish-based, low-protein diet paired with small amounts of an amino acid commonly found in eggs, meat and dairy increased healthy lifespan and decreased frailty and fat mass in mice, according to a new USC study published today in the journal Cell Metabolism.

Triple-negative breast cancer (TNBC) is aggressive and hard to treat. But the role of fat tissue in how the cancer spreads may help point toward new understanding and treatments, according to a new paper from scientists at the Hackensack Meridian Center for Discovery and Innovation (CDI) and colleagues at Georgetown University's Lombardi Comprehensive Cancer Center.

The Ross procedure, a highly specialized option for aortic valve replacement, is associated with significant long-term durability and excellent outcomes in a wide range of adult patients with aortic valve disease.

Researchers have developed a chip-based metasurface biosensor that can detect traumatic brain injury (TBI) biomarkers at extremely low levels.

The environment experienced by young zebrafish influences both the shape and electrical activity of the neurons in the eye, which impacts subsequent behavior.

A new Columbia University School of Nursing systematic review reveals access to fertility preservation (FP) care remains limited and unequal for girls and young women with cancer.

Two new studies jointly published in Nature: The Clinical Microbiome reveal that certain species of fungi in the gut play a key role in the development of immune dysregulation and some pediatric allergic diseases - and may be promising targets for new therapies.

The link between parents' body mass index (BMI) and their children's BMI in childhood is driven largely by genetic inheritance, rather than by any direct biological effects of parental weight during pregnancy, a new study suggests.

Laughter is a universal social signal that connects us with others, but the brain regions underlying laughter are not well understood, in part because it's hard to elicit genuine laughter in the lab.

If your social media feed has suddenly filled with content about ultra-processed foods (UPFs), you're far from alone. Since Health and Human Services tasked federal agencies last year with developing UPF guidelines, the buzz has been hard to miss.

A University of Minnesota Medical School research team has received a new 5-year, $3.87 million R01 grant from the National Institutes of Health (NIH) to investigate how the immune system protects against congenital cytomegalovirus (CMV) infection.

Researchers from the University of Kansas have shown a link between reproductive hormone exposure throughout life and brain health in 459 women aged 65 to 80.

A research team from University Hospitals, Case Western Reserve University and the Louis Stokes Cleveland VA Medical Center has identified a critical molecular cause of age-related cognitive decline, potentially paving the way for new treatments to protect brain health as we age.

Swallowing is a complex act requiring precise coordination of the mouth, throat, and voice box. After a stroke, damage to the brain's motor cortex can disrupt swallowing-related neural commands, leaving patients unable to clear food or liquid from their throat safely.

Wildfire smoke can trigger breathing problems and flare-ups for people with chronic obstructive pulmonary disease (COPD), yet many people are not receiving the trusted health information they need to stay safe, according to a new study in the May 2026 issue of Chronic Obstructive Pulmonary Diseases: Journal of the COPD Foundation, a peer-reviewed, open access journal.

When semaglutide's popularity exploded following FDA approval for weight management in 2021, so too did a wave of calls to poison control centers.

Scientists from the Department of Microbiology of the University of Malaga, also members of the Institute of Subtropical and Mediterranean Horticulture 'La Mayora' (IHSM), have discovered a hitherto unknown mechanism that allows the bacterium Bacillus cereus, which is responsible for food poisoning and human infections, to protect itself against antibiotics and adverse conditions.
