Immunotherapy given during and after chemoradiation did not improve survival for study participants with limited-stage, small-cell lung cancer (SCLC) according to the results of an international clinical trial, NRG-LU005, led by NRG Oncology in collaboration with the Alliance for Clinical Trials in Oncology. The results are published in the Journal of Clinical Oncology.

Biologists at the National University of Singapore (NUS) have uncovered how the protein NuSAP safeguards tiny structures inside cells called centrioles, revealing a mechanism linked to developmental disorders such as microcephaly and mosaic variegated aneuploidy (MVA) syndrome.

A randomized crossover trial found that replacing red meat patties with processed plant-based meat alternatives for six days significantly lowered circulating trimethylamine N-oxide (TMAO), a gut-derived metabolite linked to cardiovascular risk. The plant-based phase also produced modest reductions in cholesterol markers but slightly increased weight and NT-proBNP, possibly due to higher sodium intake.

Scientists tracking the entire life of the African turquoise killifish have discovered that behavior alone can predict whether an animal will live a long or short life.

Researchers identified in mice a microbiome–gut–brain pathway in which age-associated changes in gut microbes increase medium-chain fatty acids that impair vagal sensory signaling and hippocampal activity. These interoceptive disruptions weaken memory formation, revealing a microbial mechanism that contributes to cognitive decline during aging.

A team of researchers at the USC Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC has identified important differences in how early Alzheimer's disease-related brain changes appear across racial and ethnic groups, underscoring the need for more inclusive approaches to studying and diagnosing the disease.

A new preclinical study in mice shows that precancerous cells in the pancreas can be eliminated before they have the chance to become tumors.

For five decades, scientists have known about a notorious cancer-causing enzyme called SRC. But they always assumed it only appeared on the inside of cells, where it sent signals that fueled tumor growth and stayed hidden from the immune system.

A prospective feasibility study in an urgent care clinic tested a conversational AI system (AMIE) with 100 real patients to evaluate whether it could safely collect medical histories before doctor visits. The supervised AI showed no safety stops, produced diagnostic reasoning comparable to clinicians in blinded reviews, and improved patients’ attitudes toward medical AI.

As the use of injectable GLP-1 drugs continues to rise, questions persist about what happens after patients stop taking them in real-world settings.

A topical cream activated the skin's immune defenses and suppressed tumor growth in two preclinical models of cutaneous squamous cell carcinoma (cSCC), one of the most common cancers in the world, according to a study published today in the Journal of Clinical Investigation.

Hyperarousal plays an important role in mental disorders. It influences the severity of insomnia, depression, anxiety, post-traumatic stress disorder (PTSD), and ADHD.

An imaging test could safely halve the number of people who need a biopsy for suspected prostate cancer following inconclusive or reassuring results from an MRI scan, new research has found.

The kick off signal for puberty begins in the brain. Specifically, in the hypothalamus, where specific neurons release a hormone that activates the hypophysis, at the base of the skull, which then releases other hormones to start gonad –ovaries or testicles –maturation.

Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder, affecting 12%–13% of adolescents in the United States, according to some studies.

With more than 100 million neurons in the digestive tract, the gut is commonly known as the "second brain" in numerous cultures, including ancient Greece, Japan, China and India, linking digestion with physical and mental well-being.

Scientists from the University of Almería and the University of Granada, together with researchers from Leiden University Medical Center (LUMC, Netherlands), have identified an intestinal bacterium of the genus Roseburia associated with stronger muscles and improved physical condition.

New research in the March 2026 issue of JNCCN-Journal of the National Comprehensive Cancer Network suggests that exercise may help people with cancer stay mentally sharp and better able to handle daily tasks, work, and social activities through chemotherapy treatment delivered on an every two-week cycle.

Lipid nanoparticles, or LNPs, best known as the delivery vehicle for the COVID-19 mRNA vaccines received by billions of people, are now at the center of a much larger medical revolution.

OSA is a common sleep disorder characterized by oxygen desaturation due to repeated airway collapse during sleep.
