From the beginning, the moon has been humankind’s perpetual nighttime companion. Accompanied by innumerable points of light, the moon’s luminous disk hovered overhead like a dim substitute for the sun, just with a shape not so constant. Rather the moon waxed and waned, diminishing to a barely discernible sliver before disappearing and then gradually restoring […]
Boa constrictors don’t so much suffocate prey as break their hearts. It turns out that the snakes kill like demon blood pressure cuffs, squeezing down circulation to its final stop. The notion that constrictors slay by preventing breathing turns out to be wrong. The snakes don’t need limbs, or even venom, to bring down an […]
Icicles made from pure water give scientists brain freeze. In nature, most icicles are made from water with a hint of salt. But lab-made icicles free from salt disobey a prominent theory of how icicles form, and it wasn’t clear why. Now, a study is helping to melt away the confusion. Natural icicles tend to […]
Tiny, pond-dwelling Halteria ciliates are virovores, able to survive on a virus-only diet, researchers report December 27 in Proceedings of the National Academy of Sciences. The single-celled creatures are the first known to thrive when viruses alone are on the menu. Scientists already knew that some microscopic organisms snack on aquatic viruses such as chloroviruses, […]
In full swingThe swaying feeling in jazz music that compels feet to tap may arise from near-imperceptible delays in musicians’ timing, Nikk Ogasa reported in “Jazz gets its swing from small, subtle delays” (SN: 11/19/22, p. 5). Reader Oda Lisa, a self-described intermediate saxophonist, has noticed these subtle delays while playing.“I recorded my ‘jazzy’ version […]
As far back as roughly 25,000 years ago, Ice Age hunter-gatherers may have jotted down markings to communicate information about the behavior of their prey, a new study finds. These markings include dots, lines and the symbol “Y,” and often accompany images of animals. Over the last 150 years, the mysterious depictions, some dating back […]
Humankind is seeing Neptune’s rings in a whole new light thanks to the James Webb Space Telescope. In an infrared image released September 21, Neptune and its gossamer diadems of dust take on an ethereal glow against the inky backdrop of space. The stunning portrait is a huge improvement over the rings’ previous close-up, which […]
As people around the world marveled in July at the most detailed pictures of the cosmos snapped by the James Webb Space Telescope, biologists got their first glimpses of a different set of images — ones that could help revolutionize life sciences research. The images are the predicted 3-D shapes of more than 200 million […]
The answer to one of the greatest mysteries of the universe may come down to one of the smallest, and spookiest, particles. Matter is common in the cosmos. Everything around us — from planets to stars to puppies — is made up of matter. But matter has a flip side: antimatter. Protons, electrons and other […]
Face masks — the unofficial symbol of the COVID-19 pandemic — are leveling up. A mask outfitted with special electronics can detect SARS-CoV-2, the virus that causes COVID-19, and other airborne viruses within 10 minutes of exposure, materials researcher Yin Fang and colleagues report September 19 in Matter. “The lightness and wearability of this face […]
