Chemical transformations in minerals deep beneath the seafloor could explain why Indonesia’s 2004 mega-earthquake was unexpectedly destructive, researchers report in the May 26 Science. The magnitude 9.2 quake and the tsunami that it triggered killed more than 250,000 people, flattened villages, and swept homes out to sea across Southeast Asia. It was one of the […]

The first thing you’ll notice is the noise. Monitors beep steadily, relentlessly, ready to sound a car-alarm blare if a baby is in trouble. The air has an astringent odor — not clean exactly, but reminiscent of an operating room (there’s one next door). Ceiling lights shine fluorescent white. Half are off, but glare from […]

Fossil DNA may be rewriting the history of elephant evolution. The first genetic analysis of DNA from fossils of straight-tusked elephants reveals that the extinct animals most closely resembled modern African forest elephants. This suggests that straight-tusked elephants were part of the African, not Asian, elephant lineage, scientists report online June 6 in eLife. Straight-tusked […]

BOSTON — Some aspects of speech are as Southern as pecan pie. Consider the vowel shift that makes the word pie sound more like “pah.” While that pronunciation is found from Florida to Texas, a new study reveals a surprising diversity in Southern vowel pronunciation that’s linked to a speaker’s age, social class, gender, race […]

For a glue that holds up inside the body, turn to the humble slug, Arion subfuscus. A new super-sticky material mimics slug slime’s ability to stick on slick wet surfaces and could lead to more effective medical adhesives. The material has two parts: a sticky layer that attaches to a surface, and a shock-absorbing layer […]

Famously sneaky particles have been caught behaving in a new way. For the first time, scientists have detected neutrinos scattering off the nucleus of an atom. The process, predicted more than four decades ago, provides a new way to test fundamental physics. It will also help scientists to better characterize the neutrino, a misfit particle […]

The 2011 tsunami that devastated Japan’s coast cast an enormous amount of debris out to sea — way out. Japanese marine life took advantage of the new floating real estate and booked a one-way trip to America. From 2012 to 2017, at least 289 living Japanese marine species washed up on the shores of North […]

Campfire legends of massive, shaggy bipeds called yetis are grounded in a less mysterious truth: bears. Eight samples of remains such as fur, bones and teeth purportedly from mountain-dwelling yetis actually come from three different kinds of bears that live in the Himalayas, researchers report November 29 in the Proceedings of the Royal Society B. […]

COLLEGE PARK, Md. — Campus life typically challenges students with new opportunities for learning, discovery — and intimacy with germs. Lots of germs. That makes dormitories and their residents an ideal natural experiment to trace the germs’ paths. “You pack a bunch of college kids into a very small environment … we’re not known as […]

A 13-sided shape known as “the hat” has mathematicians tipping their caps. It’s the first true example of an “einstein,” a single shape that forms a special tiling of a plane: Like bathroom floor tile, it can cover an entire surface with no gaps or overlaps but only with a pattern that never repeats. “Everybody […]
