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.
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 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.
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.
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.
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.
A research team led by Jiyoung Lee, a professor in the Department of Media and Communication, has worked with international researchers to uncover how visual contrast across social media feeds influences how quickly users spot visual misinformation.
As ocean temperatures rise, corals' ability to withstand and adapt to heat stress is critical for the future of coral reefs. Many reef-building corals already live near their upper thermal limits, making them vulnerable to bleaching and, with prolonged stress, mortality.
Rats are on the ballot in Canadian municipal elections this fall, with several political parties promising to tackle city rat problems. While rats may seem like a niche election issue, they can point to broader societal concerns about housing, public services and civic engagement.
A new ice sheet model developed by glaciologists at the University of California, Irvine and NASA's Jet Propulsion Laboratory projects that the melting of Thwaites Glacier in West Antarctica will contribute up to 30 millimeters (1.2 inches) of sea level rise by 2100—twice previous estimates—even without additional climate warming.
