On the fringe of Kenya’s Gazi village, 50 kilometers south of Mombasa, Mwatime Hamadi walks barefoot on a path of scorching-hot sand toward a thicket of trees that seem to float where the land meets the Indian Ocean. Behind her moves village life: Mothers carry babies on their backs while they hang laundry between palm […]
From crabs to caterpillars, a wide range of animals successfully use camouflage to hamper detection by hungry predators. But some concealment strategies are more effective than others, a new study suggests. The analysis compiles and synthesizes data from scores of studies on animal camouflage. Comparisons between different camouflaging methods show that masquerading as specific objects […]
An experiment … at the CERN Laboratory in Geneva … gives an important clue to structural arrangements deep within the proton…. The result hints at the existence of a new and very strong fundamental interaction — the process that holds [quarks] together inside the protons.… A number of theorists have speculated about its nature and […]
Earth’s journey through the Milky Way might have helped create the planet’s first continents. Comets may have bombarded Earth every time the early solar system traveled through our galaxy’s spiral arms, a new study suggests. Those recurring barrages in turn helped trigger the formation of our planet’s continental crust, researchers propose August 23 in Geology. […]
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 […]
