Modesty is not a quality often found in abundance in physicists. Maybe that’s because Joe Polchinski had all of it. Substantial ego is arguably a necessary qualification for anyone attempting to wrest nature’s deepest secrets from their mathematical lairs. And in many cases, ego seems proportional to the magnitude of a physicist’s accomplishments. But if […]

The only fish known to hunt with wolf pack moves may not be true team players, just lemon-yellow me-firsts. Yellow saddle goatfish (Parupeneus cyclostomus) do more than school together as they dart over Indo-Pacific coral reefs. Like wolves, the goatfish take different roles in a pursuit. One or two fish may rush straight toward prey […]

Ceres may be regularly coughing up briny water or slush onto its surface. The discovery of waterlogged minerals and a growing ice wall suggests that the dwarf planet could harbor underground liquid water or slushy brine, which has escaped through cracks and craters in the recent past and may still be seeping out today. The […]

By analyzing the genome of a tiny fetal mummy known as Ata, researchers have learned more about what led to its strange-looking deformities — and that Ata was not an it, but a she. The 6-inch human mummy, found in 2003 in Chile’s Atacama Desert, contains genetic mutations associated with skeletal abnormalities and joint problems, […]

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 […]
