    Physics greats of the 20th century mixed science and public service

    The 20th century will go down in history — it pretty much already has — as the century of the physicist. Physicists’ revolutionizing of the scientific world view with relativity and quantum mechanics might have been enough to warrant that conclusion. Future historians may emphasize even more, though, the role of physicists in war and government. Two such physicists, one born at the century’s...

    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...

    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...

    ‘Cannibalism’ chronicles grisly science of eating your own

    CannibalismBill SchuttAlgonquin Books, $26.95

    Until recently, researchers thought cannibalism took place only among a few species in the animal kingdom and only under extraordinary circumstances. But as zoologist Bill Schutt chronicles in Cannibalism, plenty of creatures inhabit their own version of a dog-eat-dog world.

    Over the last few decades, scientists have observed...

    Pinhead-sized sea creature was a bag with a mouth

    A roughly 540-million-year-old creature that may have once skimmed shorelines was a real oddball.

    Dozens of peculiar, roundish fossils discovered in what is now South China represent the earliest known deuterostomes, a gigantic category of creatures that includes everything from humans to sea cucumbers.

    No bigger than a pinhead, the fossils have wrinkly, baglike bodies and gaping...

    Baby dinosaurs took three to six months to hatch

    Dinosaurs might live on today as birds, but they hatched like reptiles. Developing dinos stayed in their eggs three to six months before emerging, far longer than previously suspected, researchers report online January 3 in the Proceedings of the National Academy of Sciences.

    With few clues to dinosaurs’ embryonic lives, scientists assumed that young dinosaurs shared modern birds’ swift...
