Reanalysis suggests 'Phoebe' is a variable star, not a primordial black hole

A new study debunks a recent claim that astronomers may have detected a lunar-mass primordial black hole. In a reanalysis of observations from the Dark Energy Camera (DECam), researchers found that the star nicknamed "Phoebe" was simply doing something ordinary that many stars do

Ancient algal defenses against UV may have helped plants conquer land

A new study sheds light on how the ancestors of modern land plants survived one of the most challenging aspects of life outside water: exposure to harmful ultraviolet (UV) radiation. By examining a microscopic alga closely related to the earliest land plants, researchers have unc

Injectable silk-kudzu hydrogel achieves complete wound closure in laboratory tests

Researchers at the Terasaki Institute for Biomedical Innovation have developed an injectable hydrogel, a water-based gel material, made from silk proteins and a plant-derived compound. In laboratory tests, the material promoted complete wound closure within 72 hours, suggesting a

Brain activity under anesthesia challenges what we know about consciousness

The unconscious brain appears to be far more capable than scientists once believed. Researchers found that patients under general anesthesia could still process language at a sophisticated level, distinguishing nouns, verbs, and adjectives while listening to stories. Even more re

These tiny soil microbes could rescue crops from salty farmland

Researchers have discovered that beneficial soil bacteria give plants an unexpected survival advantage in salty soils. Instead of helping plants keep salt out, the microbes stimulate the production of lignin, a natural compound that strengthens roots and makes plants more resilie

This tiny organism contracts 200 times faster than we can blink—here's how

A tiny, aquatic, single-celled organism can contract to one-quarter of its body length in less than 5 milliseconds—hundreds of times faster than a human can blink. Researchers have discovered that the organism, Spirostomum ambiguum, uses a calcium-activated protein network in a f

DNA databases unite to create a fully open resource for transposable element research

For more than three decades, researchers studying genomes have relied on foundational resources such as Repbase and, more recently, Dfam to identify and classify transposable elements—the mobile DNA sequences that shape genome structure, evolution and function. Now, Dfam and Repb

Red-tailed hawks maintain flight performance despite missing feathers

Red-tailed hawks can compensate for feather loss during molt by subtly changing their wing and tail movements, according to a new study by University of California, Davis, researchers in the College of Engineering and the Weill School of Veterinary Medicine.

Hawaiian short-eared owl deaths in Hawaiʻi primarily caused by vehicle collisions

Trauma from vehicle collisions caused the majority of documented deaths for the Pueo (Hawaiian short-eared owl), according to a statewide study led by researchers at the University of Hawaiʻi at Mānoa. The findings represent the most extensive mortality assessment to date for thi

Psychologists survey students to determine what they really think about social media

The first findings from a major survey of more than 800 young people ages 11–17 about social media were revealed to local schoolchildren today by psychology researchers at an event on the University of Kent's Canterbury campus. Dr. Lindsey Cameron and Dr. Katie Goodbun launched T

Switching spin states in manganese ions with light opens new path for molecular memory

Researchers at Johannes Gutenberg University Mainz (JGU) have developed a new way to use molecules as tiny data storage devices with a new manganese-based material. Until now, this was possible only with iron-containing molecular materials, which require very low temperatures—ran

Unintended climate trade-off: Clean air policies intensify urban heat island in humid citi

Researchers at the University of Hong Kong (HKU) have uncovered a critical, underrecognized trade-off in global environmental policies: While essential for improving public health, large-scale air pollution reductions are unintentionally intensifying warm-season surface urban hea
