New research suggests that even light alcohol use may carry serious risks. A large study in India found that drinking just one standard drink a day is linked to a roughly 50% higher risk of mouth cancer, with the greatest danger tied to locally brewed alcohol. When alcohol use
Cannabis products with higher THC levels may slightly reduce chronic pain, particularly nerve pain, according to a review of multiple clinical trials. The improvement was small and short-lived, while side effects were more common. Products with little or no THC, including
The intermittent nature of solar energy poses challenges to grid stability, making accurate ultra-short-term solar irradiance forecasting crucial for balancing supply and demand. However, traditional numerical weather prediction models often struggle with cloud initialization,

Why does cancer sometimes recur even after successful treatment, or why do some bacteria survive despite the use of powerful antibiotics? One of the key culprits identified is "biological noise"—random fluctuations occurring inside cells.
Celebrate the New Year with the "Champagne Cluster," a galaxy cluster seen in this new image from NASA's Chandra X-ray Observatory and optical telescopes.
Immunotherapy has emerged in recent years as a new cancer treatment that is gentler than traditional chemotherapy and causes milder side effects in patients. However, conventional dendritic cell (DC) immunotherapy shows inconsistent clinical outcomes, and the cell culture
Health officials have agreed to assess pending medical research grants after a Trump administration antidiversity purge put them on ice
A spectacular fossil trove on the Arctic island of Spitsbergen shows that marine life made a stunning comeback after Earth’s greatest extinction. Tens of thousands of fossils reveal fully aquatic reptiles and complex food chains thriving just three million years later. Some
Cacio e pepe pasta and boiled eggs were the subjects of meticulous studies aiming to help cooks achieve perfection, but the reimagined recipes weren't always well-received

Thanks to Einstein’s relativity, time flows differently on Mars than on Earth. NIST scientists have now nailed down the difference, showing that Mars clocks tick slightly faster—and fluctuate over the Martian year. These microsecond shifts could play a big role in future Mars
Scientists have uncovered an extensive underwater vent system near Milos, Greece, hidden along active fault lines beneath the seafloor. These geological fractures act as pathways for hot, gas-rich fluids to escape, forming clusters of vents with striking visual diversity. The
Social media posts about unemployment can predict official jobless claims up to two weeks before government data is released, according to a study. Unemployment can be tough, and people often post about it online.
Since the interstellar object (ISO) 3I/ATLAS was first discovered on July 1, 2025, it has garnered much attention, including speculation, hopes and fears that it may somehow contain evidence of technologically advanced civilizations outside of our solar system.
