Materials can remember a sequence of events in an unexpected way
2025-01-29
UNIVERSITY PARK, Pa. — Many materials store information about what has happened to them in a sort of material memory, like wrinkles on a once crumpled piece of paper. Now, a team led by Penn State physicists has uncovered how, under specific conditions, some materials seemingly violate underlying mathematics to store memories about the sequence of previous deformations. According to the researchers, the method, described in a paper appearing today (Jan. 29) in the journal Science Advances, could inspire new ways to store information in ...
NewsGuard: Study finds no bias against conservative news outlets
2025-01-29
[Vienna, 29.01.2025]—A recent study evaluating the NewsGuard database, a leading media reliability rating service, has found no evidence supporting the allegation that NewsGuard is biased against conservative news outlets. Actually, the results suggest it’s unlikely that NewsGuard has an inherent bias in how it selects or rates right-leaning sources in the US, where trustworthiness is especially low.
“It seems unlikely that NewsGuard has an inherent bias against conservative sources, both in selecting and giving them lower ratings. Instead, the US media system is flooded with right-wing sources that tend to not adhere to professional ...

Berkeley Lab helps explore mysteries of Asteroid Bennu
2025-01-29
During the past year, there’s been an unusual set of samples at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab): material gathered from the 4.5-billion-year-old asteroid Bennu when it was roughly 200 million miles from Earth.
Berkeley Lab is one of more than 40 institutions investigating Bennu’s chemical makeup to better understand how our solar system and planets evolved. In a new study published today in the journal Nature, researchers found evidence that Bennu comes from an ancient wet world, with some material from the coldest regions of the solar system, likely beyond the orbit of ...
Princeton Chem discovers that common plastic pigment promotes depolymerization
2025-01-29
It turns out that the black plastic lid atop your coffee cup has a superpower. And the Stache Lab at Princeton Chemistry, which uncovered it, is exploiting that property to recycle at least two major types of plastic.
Their startling mechanism for promoting depolymerization relies on an additive that many plastics already contain: a pigment called carbon black that gives plastic its black color. Through a process called photothermal conversion, intense light is focused on plastic containing the pigment that jumpstarts the degradation.
So far, researchers have shown that carbon black can depolymerize polystyrene and polyvinyl chloride (PVC), two of the least recycled plastics in the planet’s ...

Life’s building blocks in Bennu samples
2025-01-29
Japanese collaborators detected all five nucleobases — building blocks of DNA and RNA — in samples returned from asteroid Bennu by NASA’s OSIRIS-REx mission.
Asteroids, small airless bodies within the inner Solar System, are theorized to have contributed water and chemical building blocks of life to Earth billions of years ago. Although meteorites on Earth come from asteroids, the combination of exposure to moisture in the atmosphere and to an uncontrolled biosphere means that interpreting the data from them is challenging. Pristine samples collected from asteroids in space would be the ideal candidates, and successful sample ...

Blood-powered toes give salamanders an arboreal edge
2025-01-29
PULLMAN, Wash. — Wandering salamanders are known for gliding high through the canopies of coastal redwood forests, but how the small amphibians stick their landing and take-off with ease remains something of a mystery.
A new study in the Journal of Morphology reveals the answer may have a lot to do with a surprising mechanism: blood-powered toes. The Washington State University-led research team discovered that wandering salamanders (Aneides vagrans) can rapidly fill, trap, and drain the blood in their toe tips to optimize attachment, detachment and general locomotion through their arboreal environment.
The research not only uncovers a previously ...
Better nurse staffing linked to fewer C-sections
