NASA has initiated the DART mission, short for Double Asteroid Redirection Test. It was launched from Vandenberg Space Force Base, California to study the effects of asteroid deflection as a method to save the Earth from future devastating collisions by asteroids. The big question…. If an asteroid is pummeling towards Earth, can humanity be saved with a simple nudge? NASA […]

■ A star college athlete has turned down a chance at sporting glory to donate bone marrow to a stranger. Cameron Lyle, a shot-putter at the University of New Hampshire, added his DNA to the federal bone marrow registry two years ago and promptly forgot about it. But this month, he discovered his marrow matched that of a 28-year-old leukemia […]

Spending evenings in front of a glowing computer, TV, or cellphone screen can put you at risk of depression, Science News reports. Nighttime exposure to light from gadgets has already been shown to contribute to insomnia, cancer, obesity, and diabetes. Now, a new study shows that screen glow can cause mood-related changes in the brain. For weeks, researchers exposed hamsters […]

Why do chimpanzees kill one another? For years, many studies have shown that chimps that were observed killing one another had become more aggressive only when humans encroached on their environment. But new studies have lent weight to an alternative theory: Chimpanzees are, like humans, natural-born killers who use violence as a means of expanding their territory and increasing their […]

Research shows there may be an entire world underneath Antarctica’s ice-free Dry Valleys, which on the surface may seem hostile to life. Below the surface lies rivers of liquid salt water which flow into subsurface lakes, every drop of which could be swarming with microbial life. One of Antarctica’s most unique features, the briny, rusty-red colored Blood Falls, could possibly […]

For the first time, a mission designed to set its eyes on black holes and other objects far from our solar system has turned its gaze back closer to home, capturing images of our sun. NASA’s Nuclear Spectroscopic Telescope Array, or NuSTAR, has taken its first picture of the sun, producing the most sensitive solar portrait ever taken in high-energy […]

Only 1 in 10,000 people have absolute or “perfect” pitch, the ability to hear a tone and tell what note it is. This unusual ability is acquired early in life, typically learned during training at about four to six years of age, and there are no records of adults acquiring the ability. But a new study shows that people who […]

Patients are getting larger and perhaps even dangerous doses of radiation from the growing number of advanced medical-imaging tests being ordered by doctors, a new study says. Researchers at the University of California, San Francisco, analyzed data from millions of patients who received medical treatment between 1996 and 2010. They found that the number of patients who underwent CT scans […]
