When visiting the center of a galaxy nicknamed J0230, pack a sturdy windproof jacket. There, you will encounter a galactic hurricane with winds whipping at about 200 million kilometers per hour. At that speed, nearly 20 percent of the speed of light, a trip around Earth would take just 0.7 seconds. These are the fastest […]

Monarch butterflies (Danaus plexippus) use their internal clock and the sun to guide them 4,000 kilometers south on their annual fall migration from eastern North America to central Mexico. Scientists have struggled to determine how butterfly brains combine visual cues from the sun with molecular timekeeping in their antennae to make the epic journey. A […]

SALT LAKE CITY — Dinosaur smarts may be a mystery, but their brains, at least, are now more concrete. A chunk of petrified brain tissue discovered in a tidal pool in southern England is the first reported from a dinosaur, researchers claim. The roughly 133-million-year-old fossil preserves the brain’s wrinkled topology, said paleontologist David Norman, […]

WASHINGTON — Diagnosing Ebola earlier is becoming almost as easy as taking a home pregnancy test. Scientists are developing antibodies for a test that can sniff out the deadly virus more quickly and efficiently than current tests, researchers reported February 6 at the American Society for Microbiology Biothreats meeting. Detecting Ebola’s genetic material in patients’ […]

In a famous series of experiments conducted in the 1970s, social psychologist Henri Tajfel asked how little it would take to persuade one group of people to discriminate against another. The answer was almost nothing. Having assigned boys to two groups based largely on random criteria, he asked them to play a game. Each boy […]

Robots are taking “dress for success” to a whole other level. A new type of shape-shifting robot can undergo complete metamorphosis in a matter of minutes. The bot is composed of a simple metal cube that wraps itself in various high-tech origami sheets that fold into wings, wheels and other appendages for getting around. By […]

Biologist Luhan Yang dreams of pig organs that will one day fly — into people. If she has her way, animal farms will raise herds of bioengineered pigs, designed to produce kidneys, livers and other organs that could be transplanted into humans. Animal parts would slip seamlessly into people, easing their suffering. “There are millions […]

Blue whales, it turns out, are a tad ambidextrous. When hunting in deep water, the whales tend to be “right-handed,” lunging at krill while twisting 180 degrees or less onto their right side. But when gobbling up the tiny crustaceans near the surface, the whales tend to be lefties, launching themselves upward while performing a […]

DNA from strands of Beethoven’s hair is helping to uncover what may have caused his death, researchers say. The composer was plagued with health issues for most of his life. On March 26, 1827, he succumbed to what many historians suspect was liver failure while in his apartment in Vienna. Now, an analysis of several […]

Gonorrhea is a wily foe. But doctors may soon have another drug to fight the sexually transmitted infection that’s become resistant to nearly every antibiotic thrown its way. In clinical trials, a new antibiotic was effective at stopping the bacteria that causes the disease. A single oral dose of the drug, called zoliflodacin, cured 96 […]
