Laser blasts might help scientists tweak Earth’s thermostat by shattering the ice crystals found in cirrus clouds. Zapping tiny ice particles in the lab forms new, smaller bits of ice, researchers report May 20 in Science Advances. Since clouds with more numerous, smaller ice particles reflect more light, the technique could combat global warming by ... Read more
U.S. 191 is one of the driving options for people headed to Grand Teton or Yellowstone National Parks. But the road also cuts through prime territory for mule deer and pronghorns. And cars and large wildlife don’t usually mix well. When they do tangle, the cars end up heavily damaged, and the animals end up ... Read more
A newly discovered species of tomato belongs in a haunted house, not on a sandwich. Fruit from the bush tomato plant Solanum ossicruentum bears little resemblance to its cultivated cousins. The Australian tomato, about a couple centimeters wide, grows enclosed in a shell of spikes. These burrs probably help the fruit latch on to the ... Read more
Social media supporters of the Islamic State, or ISIS, form online groups that may provide clues crucial to predicting when terrorist attacks will take place, a new analysis finds. These virtual communities drive ISIS activity on a Facebook-like site called VKontakte, say physicist Neil Johnson of the University of Miami in Coral Gables, Fla., and ... Read more
Scientists have found a new way to study how cancer cells divide and thrive in difficult-to-reach crannies of the body. Transparent artificial membranes — just nanometers thick — can be rolled into tubes to mimic capillaries that host spreading cancer cells, researchers report in the June ACS Nano. Cells squished inside such tubes didn’t organize ... Read more
Fluid filled with lively, churning bacteria could one day become a small-scale power source. New computer simulations indicate that a miniature wind farm‒like device could harvest the energy of chaotically swirling bacteria. That energy could be used to power micromachines or pump fluids through tiny channels. In the simulations, bacteria tended to spontaneously swim in ... Read more
Knuckleballs baffle baseball players with their unpredictable swerves. A new study suggests a possible cause of the pitch’s erratic flight — sudden changes in the drag force on a ball, due to a phenomenon called a drag crisis. The result is at odds with previous research that attributed the zigzags to the effect of airflow ... Read more
On Jupiter, the Great Red Spot is the hottest thing going. Temperatures over the ruddy oval, a storm that could engulf Earth, are hundreds of degrees warmer than neighboring parcels of air and higher than anywhere else on the planet, researchers report online July 27 in Nature. Heat from the storm might help explain why ... Read more
A roughly 27-million-year-old fossilized skull echoes growing evidence that ancient whales could navigate using high-frequency sound. Discovered over a decade ago in a drainage ditch by an amateur fossil hunter on the South Carolina coast, the skull belongs to an early toothed whale. The fossil is so well-preserved that it includes rare inner ear bones ... Read more
Capybaras, giant rodents native to South America, could become Florida’s next big invasive species, a biologist warned August 3 in Columbia, Mo., at the 53rd Annual Conference of the Animal Behavior Society. “Capybaras have been introduced to northern Florida,” said Elizabeth Congdon of Bethune-Cookman University in Daytona Beach, Fla. And there are enough similarities to ... Read more
