Moderate video gaming appears harmless, but heavy gaming may take a toll on young people’s health. Researchers found that students gaming more than 10 hours a week had worse diets, higher body weight,...
Humans pay enormous attention to lips during conversation, and robots have struggled badly to keep up. A new robot developed at Columbia Engineering learned realistic lip movements by watching its own...
A new study warns that a widely used eye ointment can damage a popular glaucoma implant. Researchers found that oil-based ointments can be absorbed into the implant’s material, causing it to swell and...
Scientists have discovered that the adolescent brain does more than prune old connections. During the teen years, it actively builds dense new clusters of synapses in specific parts of neurons. These ...
A vitamin A byproduct has been found to quietly disarm the immune system, allowing tumors to evade attack and weakening cancer vaccines. Scientists have now developed a drug that shuts down this pathw...
SpaceX Crew-11 splashed down safely in the Pacific after more than five months in orbit aboard the International Space Station. The four astronauts completed over 140 experiments and traveled nearly 7...
Researchers have identified OTULIN, an immune-regulating enzyme, as a key trigger of tau buildup in the brain. When OTULIN was disabled, tau vanished from neurons and brain cells remained healthy. The...
Hydrogen cyanide, a toxic chemical, may have helped spark the chemistry that led to life. When frozen, it forms crystals with highly reactive surfaces that can drive unusual chemical reactions, even i...
For years, strange red dots in James Webb images left scientists puzzled. New research shows they are young black holes hidden inside dense clouds of gas, glowing as they devour their surroundings. Th...
A large international study reveals that mammals tend to live longer when reproduction is suppressed. On average, lifespan increases by about 10 percent, though the reasons differ for males and female...
Scientists have uncovered how cannabis evolved the ability to make its most famous compounds—THC, CBD, and CBC—by recreating ancient enzymes that existed millions of years ago. These early enzymes wer...
Tryptophan does far more than help us sleep—it fuels brain chemistry, energy production, and mood-regulating neurotransmitters. But as the brain ages or develops neurological disease, this delicate sy...
