Extreme lightning events set records

Two electrifying light shows were much more than flashes in the pan. A 2007 thunderstorm over Oklahoma produced a lightning flash that stretched more than 321 kilometers horizontally — roughly the distance from Washington, D.C., to New York City. In southern France in 2012, a single lightning flash lit up the sky nonstop for 7.74 […]

Ancient hookups gave chimps a smidge of bonobo DNA

Like lipstick on a collar, new DNA evidence is pointing to ancient affairs between bonobos and chimpanzees. Chimps carry a small percentage of bonobo DNA, researchers report in the Oct. 28 Science. The conclusion comes from analysis of the genetic instruction books, or genomes, of 63 wild-born chimps, two captive chimps named Clint and Donald, […]

Infant brains have powerful reactions to fear

SAN DIEGO — Babies as young as 5 months old possess networks of brain cell activity that react to facial emotions, especially fear, a new study finds. “Networks for recognizing facial expressions are in place shortly after birth,” Catherine Stamoulis of Harvard Medical School said November 13 during a news conference at the annual meeting […]

Glassmaking may have begun in Egypt, not Mesopotamia

SAN ANTONIO — Ancient Mesopotamians have traditionally been credited with inventing glassmaking around 3,600 years ago. But Mesopotamians may have created second-rate knock-offs of glass objects from Egypt, where this complex craft actually originated, researchers reported November 19 at the annual meeting of the American Schools of Oriental Research. Arguments that glass production originated in […]

Cosmic test confirms quantum weirdness

The spookiness of quantum mechanics has gone cosmic. Physicists have used starlight to perform a “Bell test” to verify the strange nature of quantum mechanics. For decades, such tests have repeatedly confirmed quantum physics’s quirks, but the tests contained loopholes. While the major loopholes have already been closed (SN: 12/26/15, p. 24), a lingering caveat […]

Birth defects occur in 1 in 10 pregnancies with first trimester Zika infection

For pregnant women infected with Zika virus in the first trimester, the future is foreboding. Nearly 11 percent of U.S. women likely exposed to Zika in the early weeks of or just before pregnancy had babies or fetuses with birth defects, researchers report online December 13 in JAMA. The new study offers the first results […]

Chimps look at behinds the way we look at faces

Humans are really good at picking out faces. Our brains are so good at this that we even see faces in places they don’t exist — like Jesus on toast. Flip a face upside down, though, and the brain needs an extra moment to determine that, yes, that’s a face. This is known as the […]

Saturn’s 10th moon was the first satellite discovered in the modern space age

Tenth moon of Saturn The first natural satellite in the solar system to be discovered since artificial satellites were launched has been found circling Saturn. Dr. Audouin Dollfus of the Observatory of Physical Astronomy at Meudon, France, spotted Saturn’s tenth satellite on three photographs taken in mid-December when the planet’s rings were seen edge-on from […]

Some lucky birds escaped dino doomsday

The asteroid strike (or was it the roiling volcanoes?) that triggered dino doomsday 66 million years ago also brought an avian apocalypse. Birds had evolved by then, but only some had what it took to survive. Biologists now generally accept birds as a kind of dinosaur, just as people are a kind of mammal. Much […]

Five gamma-ray blazars set new distance record

WASHINGTON — Scientists have spotted a quintet of record-breaking blazars. The five gamma-ray blazars — supremely bright galaxies that host supermassive black holes — are the most distant ever spotted, at more than 11.7 billion light-years away. As a gamma-ray blazar’s black hole swallows up matter, bright jets shoot out of the galaxy at close […]
