Cinematic geologists are usually good guys—sometimes gals—but they have a one in three fatality rate, a film analysis show

Hidden chambers may provide Mediterranean monk seals refuge from tourists

Cannabis use among older adults is rising fast, but today’s marijuana is far more potent than many people realize — and experts warn the risks may be underestimated. Stanford Medicine specialists say modern cannabis can increase the chances of heart problems, falls, memory issues, dangerous drug interactions, and even addiction, especially for people over 65.

Scientists have uncovered a surprising dark side to vitamin B2: it may help cancer cells stay alive. The vitamin supports a cellular shield that protects tumors from ferroptosis, a form of programmed cell death linked to cancer suppression. In lab tests, researchers used a vitamin B2-like compound called roseoflavin to break down that protection and trigger cancer cell death.

Scientists have uncovered evidence that serotonin — the same brain chemical boosted by many antidepressants — may actually worsen tinnitus. Using advanced light-based brain stimulation in mice, researchers identified a serotonin-driven circuit linked directly to tinnitus-like behavior. The findings may explain why some people experience louder ringing in their ears while taking SSRIs.

Relocating plants’ light-capturing structures to the eye may fight damage from dry eye

Researchers analyzing over 20,000 patients found that very high levels of the inherited cholesterol particle Lp(a) dramatically raise the risk of stroke, cardiovascular death, and major heart complications. Because most people with elevated Lp(a) have no symptoms, experts say a simple blood test could uncover a dangerous hidden risk factor.

SMILE orbiter will use x-rays to map how the solar wind batters the magnetosphere

The global increase in neurodegenerative disorders such as Alzheimer's disease has prompted the search for effective non-pharmacological interventions. Chrono-exercise which is the physical training aligned with circadian rhythms has emerged as a novel strategy to strengthen cognitive resilience. This study explores the impact of chrono-exercises, incorporating aerobic, resistance, and combined modalities, performed at the early dark (ZT13) and early light (ZT1) phases in an aluminum chloride...

A casual conversation between graduate students helped spark a breakthrough in aging research at Mayo Clinic. Researchers discovered that tiny synthetic DNA molecules called aptamers can selectively attach to senescent “zombie cells,” which are linked to aging, cancer, and neurodegenerative disease. The method could eventually help scientists identify and target these cells in living tissue with far greater precision.

A groundbreaking Swedish study that tracked people for nearly 50 years has revealed when the body’s physical decline quietly begins. Researchers found that fitness, strength, and muscle endurance start slipping around age 35, with the decline accelerating over time. But there’s an encouraging twist: adults who became active later in life still improved their physical performance by up to 10 percent.

Colorectal cancer is increasingly showing up in younger adults, with cases now appearing in people as young as their thirties — often with no family history or warning signs. A major Swiss study analyzing nearly 100,000 cases over four decades found that diagnoses in people under 50 have been steadily climbing, even as rates fall among older adults thanks to screening programs. Researchers say younger patients are also more likely to be diagnosed late, after the cancer has already spread.
