Scary tomato appears to bleed

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

Monitoring online groups offers insight into ISIS attacks

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

Tight spaces cause spreading cancer cells to divide improperly

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

Mini ‘wind farm’ could capture energy from microbes in motion

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

Scientists throw a curve at knuckleball explanation

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

Jupiter’s Great Red Spot is hot

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

New fossil suggests echolocation evolved early in whales

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 may be poised to be Florida’s next invasive rodent

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

How to get Ötzi’s look

Ötzi had Copper Age style. The 5,300-year-old Tyrolean Iceman, whose body was found poking out of a glacier in the Italian Alps in 1991, incorporated hides from at least five domesticated and wild animal species into his apparel, a new genetic study finds. Comparing mitochondrial DNA extracted from nine ancient leather fragments with DNA of ... Read more

CRISPR inspires new tricks to edit genes

Scientists usually shy away from using the word miracle — unless they’re talking about the gene-editing tool called CRISPR/Cas9. “You can do anything with CRISPR,” some say. Others just call it amazing. CRISPR can quickly and efficiently manipulate virtually any gene in any plant or animal. In the four years since CRISPR has been around, ... Read more
