Wild bobwhite quail spotted after habitat restoration project‎

Multiple coveys of wild bobwhite quail were recently sighted at the University of Tennessee's Ames AgResearch and Education Center, marking an encouraging milestone in an ongoing effort to restore habitat for the species at this historic bird dog field trial destination.

Black women in food industries face systemic roadblocks‎

Lilly Jan was perplexed and a little annoyed. Last year, Jan, an assistant teaching professor in the Cornell Nolan School of Hotel Administration in the Cornell SC Johnson College of Business, was trying to collect information on food industry businesses owned by Black women.

Simple cleaning steps could curb deadly fungal disease risks for Australia's wild reptiles‎

With spring underway and the weather warming, reptiles are on the move in suburbs, parks and scrubland across Australia. Snake catchers and wildlife caregivers are responding to calls for help, and reptile enthusiasts—known as "herpers"—are heading outdoors in search of their next sighting.

Ultrashort laser pulses offer a new way to probe electrons' quantum geometry‎

Researchers at Friedrich Schiller University Jena and the University of Regensburg have developed a method for determining, using light, a quantum property of electrons that has hitherto been difficult to access. The focus is on what is known as Berry curvature—a quantity that describes certain geometric properties of the quantum mechanical states of electrons. The researchers measured it in a layer of the semiconductor tungsten diselenide, just one atomic layer thick, using ultrashort laser pulses. The results have been published in the latest issue of the journal Nature Photonics.

Scientists discover 'D-rex', a giant fungus from Chinese forests whose unique lineage dates back 65 million years‎

Deep in the forests of Yunnan, China, scientists have discovered a "fungal giant" that challenges our understanding of how large fungi can become. The newly described species, Dianjunus rex, produces vertical fruiting bodies up to 50 cm (20 inches) high and weighing up to 2.2 kg (4.9 pounds)—the largest known within the phylum Ascomycota.

Isle of Wight fossil Europe's first known long-clawed megaraptoran dinosaur‎

A new species of dinosaur—a long-clawed predator the size of a large tiger—has been discovered by a UCL-led team from a fossil found on the Isle of Wight. The dinosaur, described in a new paper in the journal Royal Society Open Science, belongs to a group of agile, two-legged carnivores called megaraptorans and is the first of this group to be found in Europe.

People with a 'good ear' for sounds make better language learners, study suggests‎

People who are better at noticing fine details in sound—an ability known as auditory precision—can master the pronunciation of new languages faster and more accurately than other learners, a new study published in the Journal of Experimental Psychology finds.

Optical skyrmions can control the motion of magnetic skyrmions‎

Magnetic skyrmions (MSks) are swirling patterns of magnetization that form inside certain magnetic materials. They can behave like actual particles in many ways, exhibiting a stable internal structure and distinct boundaries. Because they are extremely small and can be pushed around with relatively little energy, MSks are regarded as promising information carriers in emerging technologies, including low-power memories and logic circuits. However, a major goal in the field has been to find practical ways to control their motion with high precision.

Patterned X-rays map 3D chemical structures faster with fewer measurements‎

Seeing inside an object is one thing; seeing exactly what it is made of, in three dimensions, is far more difficult. Now, researchers at Bar-Ilan University and collaborating institutions have developed a new X-ray imaging technique that can map the three-dimensional chemical composition of an object 43 times faster than conventional approaches, while using more than 97% less measurement data.

Computational model guides lighting design to improve color discrimination in aging eyes‎

Researchers have developed a new computational model that accounts for the effects of aging on our eyes' ability to discriminate color. It could help guide lighting designs that make it easier for older adults to perceive colors while preserving the expected appearance for people with typical color vision.
