The sun's outbursts may briefly weaken rain and snow events across North America

For decades, scientists have searched for a clear link between the sun's explosive storms and the weather that occurs on Earth. A breakthrough study from the University of New Hampshire reveals that in the hours and days following a solar storm, parts of North America can see sha

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

The order of species loss alters how grasslands maintain stability, study finds

Grasslands account for roughly 40% of terrestrial ecosystems and are paramount to global food security. Wild grasslands provide food for livestock and habitat for pollinators and act as a carbon sink in the era of climate change. Maintaining the health of native grasslands is a c

Camera traps reveal the true culprit behind crop damage in Honduras

A new study from the Honduran Mosquitia shows how simple, noninvasive technology can help solve one of the most common challenges in wildlife conservation: identifying the species actually responsible for crop damage. The full detailed results have been published in Neotropical B

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

Age bias discovered in AI

Do responses generated by artificial intelligence systems such as ChatGPT reflect social prejudice? A KAIST research team has quantitatively analyzed and identified age-related stereotypes embedded in the responses of generative artificial intelligence. The study sheds light on t

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.

Giraffes combine quantities similarly to addition

In addition to humans, some species of primates and birds have demonstrated under experimental conditions their ability to manipulate quantities in tasks that require combining or separating them, in a manner similar to addition or subtraction. Now, a study by the University of B

Solar storms leave their mark on cosmic rays that reach Earth

A new study has revealed an unexpected link between solar storms and the flux of high-energy cosmic rays arriving at Earth. The findings, made using one of the world's largest cosmic ray detectors, could open up a new way to probe the magnetic structures inside solar storms—and p

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

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
