Your bedroom glow might be quietly damaging your heart Boston researchers linked nighttime light exposure to greater stress-related brain activity and inflamed arteries, signaling a higher risk of heart disease. The study suggests that artificial light at night disrupts normal stress responses, leading to chronic inflammation. Experts call for reducing unnecessary light in cities and homes to protect cardiovascular health.

Scientists find 15 gut bacteria that may drive heart disease Scientists in Seoul have uncovered 15 gut bacterial species linked to coronary artery disease, showing that microbes can influence heart health far beyond digestion. Their findings reveal how shifts in gut microbial function — including inflammation, loss of protective species, and overactive metabolic pathways — may drive disease progression. Intriguingly, even “good” bacteria like Faecalibacterium prausnitzii and Akkermansia muciniphila can become harmful under certain conditions.

The body trait that helps keep your brain young Scientists discovered that more muscle and less hidden abdominal fat are linked to a younger biological brain age. Deep visceral fat appeared to accelerate brain aging, while muscle mass offered a protective effect.

Doctors are seeing more aggressive breast cancer in younger women than expected Younger women are being diagnosed with breast cancer more often than screening guidelines anticipate. Many of these cancers are invasive and harder to treat, especially in those under 40. After analyzing 11 years of data, researchers found that this age group makes up a steady and significant share of diagnoses. The results support a stronger push for earlier risk evaluation.

Stanford’s tiny eye chip helps the blind see again A wireless eye implant developed at Stanford Medicine has restored reading ability to people with advanced macular degeneration. The PRIMA chip works with smart glasses to replace lost photoreceptors using infrared light. Most trial participants regained functional vision, reading books and recognizing signs. Researchers are now developing higher-resolution versions that could eventually provide near-normal sight.
