    Citizen scientists are providing stunning new views of Jupiter

    Stormy, with a good chance of cyclones. That’s the forecast for Jupiter’s south pole — a region never seen before but quickly coming into focus with the help of citizen scientists.

    Music producer Roman Tkachenko’s edited image of Jupiter’s nether regions (featured above) is a perfect example. His enhancements make the swirling cyclones and white oval storms really pop compared with the...

    Speech recognition has come a long way in 50 years

    Computers that hear

    Computer engineers have dreamed of a machine that would translate speech into something that a vacuum tube or transistor could understand. Now at last, some promising hardware is being developed.... It is still a long way from the kind of science fiction computer that can understand sentences or long speeches. — Science News, March 4, 1967

    Sound waves could take a tsunami down a few notches

    A tsunami’s immense wall of water may not be stoppable. But there may be a way to take the ferocious force of nature down a few notches, using a pair of counterwaves.

    If released at the right moment, a type of sound wave known as an acoustic-gravity wave could subdue a tsunami, applied mathematician Usama Kadri of Cardiff University in Wales reports January 23 in Heliyon. These acoustic-...

    Mapping rainforest chemistry from the air reveals 36 types of forest

    To some forest creatures, a tree is a home. To scientists, it’s a beacon. A new way of mapping forests from the air by measuring chemical signatures of the tree canopy is revealing previously unrecognized biodiversity.

    The swath of tropical forest covering the Peruvian Andes Mountains and the Amazon basin is one of the most biodiverse places on Earth. But it’s such a wild and remote...

    Physically abused kids learn to fail at social rules for success

    Physical abuse at home doesn’t just leave kids black and blue. It also bruises their ability to learn how to act at school and elsewhere, contributing to abused children’s well-documented behavior problems.

    Derailment of a basic form of social learning has, for the first time, been linked to these children’s misbehavior years down the line, psychologist Jamie Hanson of the University of...

    Germanium computer chips gain ground on silicon — again

    First germanium integrated circuits

    Integrated circuits made of germanium instead of silicon have been reported … by researchers at International Business Machines Corp. Even though the experimental devices are about three times as large as the smallest silicon circuits, they reportedly offer faster overall switching speed. Germanium … has inherently greater mobility than silicon, which...

    How hydras know where to regrow their heads

    View the video

    Hydras, petite pond polyps known for their seemingly eternal youth, exemplify the art of bouncing back. The animals’ cellular scaffolding, or cytoskeleton, can regrow from a slice of tissue that’s just 5 percent of its full body size. Researchers thought that molecular signals told cells where and how to rebuild, but new evidence suggests there are other forces at play....

    Observers caught these stars going supernova

    In A.D. 185, Chinese records note the appearance of a “guest star” that then faded away over the span of several months. In 1572, astronomer Tycho Brahe and many others watched as a previously unknown star in the constellation Cassiopeia blasted out gobs of light and then eventually disappeared. And 30 years ago, the world witnessed a similar blaze of light from a small galaxy that orbits the...

    When a nearby star goes supernova, scientists will be ready

    Almost every night that the constellation Orion is visible, physicist Mark Vagins steps outside to peer at a reddish star at the right shoulder of the mythical figure. “You can see the color of Betelgeuse with the naked eye. It’s very striking, this red, red star,” he says. “It may not be in my lifetime, but one of these days, that star is going to explode.”

    With a radius about 900 times...

    30 years later, supernova 1987A is still sharing secrets

    Ian Shelton was alone at a telescope in the remote Atacama Desert of Chile. After three hours getting a picture of the Large Magellanic Cloud, a wispy galaxy that orbits the Milky Way, he was plunged into darkness. High winds had taken hold of the rolltop door in the observatory’s roof, slamming it shut.

    “This was maybe telling me I should just call it a night,” says Shelton, who was a...
