Eating more sugar while taking antibiotics was linked to greater disruption of the gut microbiome and increased growth of potentially harmful bacteria. Researchers say temporarily cutting back on sweets during and after antibiotic treatment could be a simple way to reduce this...
Scientists at UC San Francisco have developed a way to create cancer-fighting CAR-T cells directly inside the body, potentially avoiding the slow and extremely expensive process of removing, engineering, and reinfusing a patient’s immune cells. Using a two-particle delivery sy...
Scientists discovered that disrupting the chemical messages bacteria use to communicate can push dental plaque toward a healthier microbial balance. The approach could lead to new treatments for gum disease that control harmful bacteria without destroying beneficial species.
Cannabinoids may intensify anxiety by removing a natural brake on specific neurons in the brain’s fear center, particularly during stressful situations. In mice, shutting down those neurons sharply reduced cannabinoid-related anxious behavior.
Imports of nicotine-free e-cigarette liquid in South Korea more than doubled to $9.2 million in the first eight months of 2026 from $4.5 million a year earlier. The post South Korea Sees Surge in Nicotine-Free Vape Imports first appeared on Tobacco Reporter.
Colorectal cancer in young people is often diagnosed at an advanced stage, with researchers finding most patients age 21 or younger already had Stage III or IV disease. Because symptoms like rectal bleeding, weight loss, abdominal pain, and bowel changes may be overlooked, res...
Couples who exercise together report better communication, healthier conflict resolution, and lower marital stress than those who work out alone. Even something as simple as taking a walk together may create valuable opportunities to talk, listen, and feel more connected.
New mothers paired with patient navigators were much more likely to receive postpartum care, depression screening, preventive testing, and ongoing primary care. By helping with barriers such as transportation, childcare, scheduling, and confusing medical information, navigator...
Thousands of people who die by suicide experience chronic pain before they end their lives. It's a tragedy I've seen up close, a stark reminder that suicide prevention must include patients living with pain—and the families who live with loss.
A ketogenic diet increased small-intestinal tumors in cancer-prone mice while reducing tumors in the colon, revealing a strikingly different response within neighboring parts of the gut. Researchers traced the increased risk not to ketones, but to the way intestinal stem cells...
Emergency Departments (EDs) could play a much greater role in helping smokers quit, turning an acute health event into an opportunity to initiate smoking cessation. This is the central message […]
Scientists found that prolonged fasting triggers major changes throughout the body, but many of the most interesting effects only appeared after about three days without food. The results suggest fasting may influence health in ways that go beyond weight loss and could eventua...
Scientists have discovered a human gene with a remarkable double life: it appears to play an important role in brain cells while still retaining the ability to jump around the genome. Called BC200, the gene evolved millions of years ago from a mobile piece of DNA known as a tr...
Cancer immunotherapy can lose its punch when tumor-fighting T cells become exhausted, but researchers may have found a way to keep them going longer. Scientists at Memorial Sloan Kettering Cancer Center identified a signaling molecule called MEK that can push T cells to burn t...
Scientists have discovered that E-cadherin, a protein best known as the “glue” holding cells and tissues together, has a surprising second job: helping epithelial cells swallow nearby dead cells. Using live zebrafish and mouse embryos, researchers found that cells can dramatic...
