DNA is setting the record straight on ancient Canaanites. For the first time, scientists have deciphered the complete genetic instruction manuals of Canaanites. By comparing five Canaanite genomes with those of other ancient and modern populations, the researchers identified the Canaanites’ ancestors and discovered their descendants, modern Lebanese people. The results, reported online July 27 […]
Biologist Luhan Yang dreams of pig organs that will one day fly — into people. If she has her way, animal farms will raise herds of bioengineered pigs, designed to produce kidneys, livers and other organs that could be transplanted into humans. Animal parts would slip seamlessly into people, easing their suffering. “There are millions […]
A new discovery is turning the hemispheric history of a mysterious whale species upside-down. Two fossils recently unearthed in Italy and Japan suggest that a southern whale was briefly a denizen of northern waters more than half a million years ago. Until now, all available evidence suggested that the pygmy right whale, Caperea marginata, and […]
BOSTON — Getting your groove on solo with headphones on might be your jam, but it can’t compare with a live concert. Just ask your brain. When people watch live music together, their brains waves synchronize, and this brain bonding is linked with having a better time. The new findings, reported March 27 at a […]
Umbilical cords tie mother and baby together, if only for a brief spell. But the stuff inside these cords has the potential to be useful well after birth. Cells in umbilical cord blood are already being used to treat certain diseases, including leukemia and rare forms of anemia. But for all the excitement about umbilical […]
In turquoise waters off the Indonesian coast, evolutionary geneticist Melissa Ilardo watched as the diver, wearing handmade, wooden goggles, spotted a giant clam meters below and darted down to retrieve it. The diver was one of the Bajau people of Southeast Asia, known for holding their breath for long periods while spearing fish and gathering […]
Pluto’s largest moon, long seen as a mysterious smudge at the outer reaches of our solar system, was revealed in 2015 closeup images to be pocked with craters, mountains and steep-sided depressions called chasmas. Now, 12 of those topographical features have names. Charon’s six most prominent craters were named for fictional explorers, including Dorothy who […]
In a transplant first, a U.S. veteran severely injured by an explosive device in Afghanistan has received a penis and scrotum from a deceased donor. During the 14-hour surgery at Johns Hopkins School of Medicine, doctors removed the patient’s damaged tissues and connected three arteries, four veins, two nerves and the urethra to the donated […]
Astronomers are going gaga over Gaia. The April 25 release of data from the European Space Agency’s Gaia spacecraft, which cataloged nearly 1.7 billion stars, has kicked off a scientific spree, with multiple papers published online in the last two weeks at arXiv.org. Charting stars in the Milky Way and beyond, Gaia surveys the entire […]
Protons are no one-trick ponies. Although famous for their positive electric charge, the particles also carry an analogous, lesser-known charge, called the weak charge. Now, physicists have made the most precise measurement of the proton’s underdog attribute, members of the Q-weak experiment report in the May 10 Nature. The weak charge dictates how the proton […]
