A set of physical exercises designed based on oracle bone inscriptions has been publicized to promote traditional Chinese culture and language by China's Ministry of Education. The exercises were initiated by Anyang Normal University (ANU) in Central China's Henan Province and designed by its School of Music. Consisting of 19 characters of the oracle […]
There’s a deadly fungus spreading among snakes in the United States. But don’t cheer. As much as snakes might frighten us, they’re important players in the ecosystem, and we really don’t want to lose them. In 2006, scientists discovered some odd skin infections among snakes in declining populations in New Hampshire. Soon after, fungal infections […]
The Zika virus may have hopped a ride on a 747 from Southeast Asia in 2013 to invade the Americas. Oliver Pybus, an evolutionary biologist at the University of Oxford, and his colleagues have retraced the virus’ steps in Brazil and pinpointed its introduction there to between May and December 2013. That coincides with a […]
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 […]
Ant antennae don’t just receive chemical signals — they send them, too. Colonies of ants communicate through chemical cues produced all over their bodies. Studies have shown that ants use their antennae to identify their own nest-mates and potential invaders. But antennae also produce the key compounds that ants use to tell friend from foe, […]
Joni Mitchell was right: We are stardust. Another one of the essential ingredients for life as we know it might have formed in space and then rained down on a young Earth, researchers suggest in the April 8 Science. The simple sugar ribose — a crucial piece of the molecular machinery inside cells — can […]
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 […]
An X-ray space telescope that went silent last month has been officially declared dead. The Japanese space agency, JAXA, announced April 28 that it has stopped trying to communicate with the orbiting observatory ASTRO-H (aka Hitomi) and will now focus on figuring out what went wrong. ASTRO-H launched on February 17 and seemed to be […]
Fossil discoveries in southern China point to an evolutionary crossroads around 34 million years ago that resulted in humans evolving in Africa rather than Asia, scientists say. A sharply cooler and drier climate at that time, combined with upheavals of landmasses that forged the Himalayas and the Tibetan Plateau, destroyed many tropical forests in Asia. […]
Turns out, it is possible to be a lucky snakebite victim. Depending on the circumstances (and the snake’s mood, presumably), a timber rattlesnake may choose to strike its prey with only one fang and to pump out little or no venom when it does so. Far from being mindless, hair-triggered biting machines, timber rattlers don’t […]
