On a Hawaiian mountaintop in the summer of 1992, a pair of scientists spotted a pinprick of light inching through the constellation Pisces. That unassuming object — located over a billion kilometers beyond Neptune — would rewrite our understanding of the solar system. Rather than an expanse of emptiness, there was something, a vast collection […]
Even spiders, it seems, have fallen victim to misinformation. Media reports about people’s encounters with spiders tend to be full of falsehoods with a distinctly negative spin. An analysis of a decade’s worth of newspaper stories from dozens of countries finds that nearly half of the reports contain errors, arachnologist Catherine Scott and colleagues report […]
Chicxulub, the asteroid that wiped out most dinosaurs, might have had a little sibling. Off the coast of West Africa, hundreds of meters beneath the seafloor, scientists have identified what appears to be the remains of an 8.5-kilometer-wide impact crater, which they’ve named Nadir. The team estimates that the crater formed roughly around the same […]
Sea urchin skeletons may owe some of their strength to a common geometric design. Components of the skeletons of common sea urchins (Paracentrotus lividus) follow a similar pattern to that found in honeycombs and dragonfly wings, researchers report in the August Journal of the Royal Society Interface. Studying this recurring natural order could inspire the […]
It’s not easy being ringed. A newly released image from the James Webb Space Telescope, or JWST, shows the Cartwheel Galaxy still reeling from a run-in with a smaller galaxy 400 million years ago. The Cartwheel Galaxy, so called because of its bright inner ring and colorful outer ring, lies about 500 million light-years from […]
Lionfish certainly aren’t the fastest predators on the reef, but new research suggests that they can catch swift prey through pure tenacity, gliding slowly in pursuit until the perfect moment to strike. The finding may help explain part of the lionfish’s impact as an invasive species, and reveal a key hunting strategy that other relatively […]
By his count, Michel Roccati is on his third life, at least. In the first, he was a fit young man riding his motorcycle around Italy. A 2017 crash in the hills near Turin turned him into the second man, one with a severe spinal cord injury that left him paralyzed from the waist down. […]
Call it cellular life support for dead pigs. A complex web of pumps, sensors and artificial fluid can move oxygen, nutrients and drugs into pigs’ bodies, preserving cells in organs that would otherwise deteriorate after the heart stops pumping. The finding, described August 3 in Nature, is preliminary, but it hints at new ways to […]
Sometimes a photo is literally a matter of life, death — and zombies. This haunting image, winner of the 2022 BMC Ecology and Evolution photography competition, certainly fits that description. It captures the fruiting bodies of a parasitic fungus, emerging from the lifeless body of an infected fly in the Peruvian rainforest. The fungus-infested fly […]
Archaeologist Peter Bellwood’s academic odyssey wended from England to teaching posts halfway around the world, first in New Zealand and then in Australia. For more than 50 years, he has studied how humans settled islands from Southeast Asia to Polynesia. So it’s fitting that his new book, a plain-English summary of what’s known and what’s […]
