New wastewater disposal regulations in Oklahoma will be enough to steady the state’s shaky ground, new research predicts. The injection of wastewater from oil and gas operations into underground wells has caused Oklahoma’s seismic activity to skyrocket (SN: 8/9/14, p. 13). In response, state regulators earlier this year ordered a 40 percent reduction in the […]

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 […]

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 […]

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 […]

These findings would have rocked the scientific world, if only the evidence had been more convincing. New Planet 9 cluesA giant planet lurking at the outskirts of the solar system could explain the odd orbits of far-flung hunks of icy debris (SN: 2/20/16, p. 6). If the planet exists, its average distance from the sun […]

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 […]

Zoom in on a soap bubble just before it bursts and brilliant, complex patterns emerge. Shimmery rainbows appear in thicker portions of the soap film, while clusters of dark spots appear in the thinnest regions. The thickness of the soap film determines the color seen. Light rays that reflect off of the top and bottom […]

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 […]

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 […]

WASHINGTON — Scientists usually worry that animal diseases could spill over into humans. But “spillback” of Zika virus into monkeys in South America could be just as dangerous. In areas where Zika infections are prevalent among humans and mosquitoes are abundant, the virus may be transmitted to wild primates, disease ecologist Barbara Han said February […]
