A team of researchers from France, Sweden, and Denmark have identified a new strain of Yersinia pestis, the bacteria that causes plague, in DNA extracted from 5,000-year-old human remains. Their analyses, publishing December 6 in the journal Cell, suggest that this strain is the closest ever identified to the genetic origin of plague. Their work

Geckos are renowned for their acrobatic feats on land and in the air, but a new discovery that they can also run on water puts them in the superhero category, says a University of California, Berkeley, biologist. “They can run up a wall at a meter per second, they can glide, they can right themselves

An active protein component of royal jelly helps honeybees create new queens. Stanford researchers have identified a similar protein in mammals, which keeps cultured embryonic stem cells pluripotent. A mammalian protein similar in structure to the active component of honeybee royal jelly—the queen-making goop that helps worker bees raise a new egg-laying diva for the

Lonesome George’s species may have died with him in 2012, but he and other giant tortoises of the Galapagos are still providing genetic clues to individual longevity through a new study by researchers at Yale University, the University of Oviedo in Spain, the Galapagos Conservancy, and the Galapagos National Park Service. Genetic analysis of DNA

Scientists studying the digestive system of a curious wood-eating crustacean have discovered it may hold the key to sustainably converting wood into biofuel. Gribble are small marine invertebrates that have evolved to perform an important ecological role eating the abundant supplies of wood washed into the sea from river estuaries. They can also be something

Some lizards in the eastern U.S. have adapted to invasive fire ants — which can bite, sting, and kill lizards — reversing geographical trends in behavioral and physical traits used to avoid predators. A new study describing this reversal appears online on November 29, 2018, in the journal Global Change Biology and reveals that new

Rivaling the evolution of feathers in dinosaurs, one of the most extraordinary transformations in the history of life was the evolution of baleen — rows of flexible hair-like plates that blue whales, humpbacks and other marine mammals use to filter relatively tiny prey from gulps of ocean water. The unusual structure enables the world’s largest

Ancient wildfires played a crucial role in the formation and spread of grasslands like those that now cover large parts of the Earth, according to scientists at Penn State and the Smithsonian National Museum of Natural History. A new study links a large rise in wildfires nearly 10 million years ago, in the late Miocene,

Place cells in the hippocampus fire when we are in a certain position — this discovery by John O’Keefe, May-Britt Moser and Edvard Moser brought them the Nobel Prize in Medicine in 2014. Based on which place cell fires, scientists can determine were a rat is. Neuroscientists are now able to tell where a rat

Microbes could have performed oxygen-producing photosynthesis at least one billion years earlier in the history of the Earth than previously thought. The finding could change ideas of how and when complex life evolved on Earth, and how likely it is that it could evolve on other planets. Oxygen in the Earth’s atmosphere is necessary for
