When a species of nightshade is injured by hungry beetles, it produces sugary nectar at the wound site. The nectar attracts ants that then keep the beetles at bay.
Mundane notes about daily life on 16 ceramic shards written about 600 B.C. at an ancient military fortress in the Negev Desert reveal that literacy had to be common.
Some white storks have stopped migrating from Europe to sub-Saharan Africa in the winter, because of the availability of food in landfills.
Antibiotics work against bacterial infections but are often prescribed to people with viral infections, which don't respond to the drugs. But a new gene test could show if a patient's infection is viral or bacterial.
Sophisticated computational techniques make it possible to analyze gene samples from all the bacteria in the gut at once to take a census of the species present.
Researchers were able to determine the genome of stomach bacteria that infected the famous Iceman at the time of his death, in the process giving us clues about ancient human migrations.
Closely tracking 800 people's blood glucose levels in response to meals allowed researchers to develop a predictive algorithm for individuals
A tree survey in the Amazon by more than 150 researchers led to an estimate that up to 57 percent of Amazon trees could qualify for threatened species status by 2050
Fruits growing wild in urban areas were found to be healthful and to contain lower levels of lead than what's considered safe in drinking water
Beeswax residues found on shards of stone age pottery in the Mediterranean region indicate that humans were keeping honeybees as early as 9,000 years ago
Researchers picked apart satellite imagery from two New England forest ecosystems to get a better handle on exactly what factors influence the timing of the color changes of the autumn leaves
New research on mice demonstrates a way to use designer bacteria as a non-invasive test for cancer.
Early human species may have had sharper hearing in certain frequencies than we enjoy, to facilitate short-range communication in an open environment. Cynthia Graber reports
Domesticated pigs had many dalliances with wild boars that added new genes to the pig population well after they had settled down on the farm
Whereas most predators kill the young or infirm, humans claim a disproportionate number of mature healthy adults of reproductive age
Researchers linked dated graffiti about droughts in a cave in China to physical evidence in the cave of the water shortages, such as changes in ratios of stable isotopes in specific layers of stalagmites
Both hemispheres are involved in the brains of people interpreting a whistled variant of Turkish, compared with a left hemisphere dominance when listeners hear the spoken language
Microbes 2,500 meters below the seafloor in Japan are most closely related to bacterial groups that thrive in forest soils on land, suggesting that they might be descendants of ones that survived when their terrestrial habitat was flooded 20 million years ago
Adults of the west African Baka people and east African Efé and Sua peoples average less than five feet tall. But while the Efé and Sua are born small, the Baka have slow growth rates in infancy
A survey of nearly 5,000 13- to 15-year-olds in the U.K. found that 40 percent of overweight and obese teens did not self-identify as “too heavy.” Cynthia Graber reports
