Aging zoo animals threaten long-term species conservation goals
Many mammal populations in European and North American zoos are aging—a trend that jeopardizes the long-term viability of so-called reserve populations and, wit...
2D topological crystalline insulator turns decade-old prediction into reality
Physicists from University of Jyväskylä and Aalto University (Finland) have experimentally realized a two-dimensional topological crystalline insulator. This is...
South Africa's Kruger park suffers 'devastating' damage from floods
South Africa's iconic Kruger National Park suffered major damage to critical infrastructure in recent flooding, with the cost of repairs estimated to run over 3...
Rule-breaking supermassive black hole discovered in the early universe
An international research team led by scientists at Waseda University and Tohoku University has discovered an extraordinary quasar in the early universe that ho...
Webb telescope reveals galaxy cluster's gravity warping light from distant galaxies
This NASA/ESA/CSA James Webb Space Telescope Picture of the Month brings us a scene from the distant universe. Pictured here is the galaxy cluster MACS J1149.5+...
Four-eyed Cambrian fish fossils hint at origins of vertebrate pineal complex
New fossil evidence from China suggests that some of our vertebrate ancestors had four eyes. The study, published in Nature, takes a closer look at a structure...
Rainfall–salinity link sustains prolonged La Niña events, study reveals
La Niña—a climate phenomenon characterized by unusually cool sea surface temperatures in the central and eastern tropical Pacific Ocean—can persist for multiple...
Ancient giant kangaroos could hop to it when they needed to, hindlimb study suggests
Giant ancestors of modern-day kangaroos—which previous research has estimated could weigh up to 250 kilograms—may have been able to hop in short bursts, accordi...
NASA's Artemis II mission to fly legacy keepsakes with astronaut crew
As America approaches its 250th anniversary of declaring independence, NASA's Artemis II mission will carry a host of mementos that reflect the nation's long tr...
Study challenges long-held theory that language is built on grammar trees
Every time we speak, we're improvising. "Humans possess a remarkable ability to talk about almost anything, sometimes putting words together into never-before-s...
DNA nanodevices reveal acidic nanolayer on lysosome surfaces in live cells
Lysosomes are membrane-bound organelles whose acidic lumen (pH 4.5–5.0) is required for degradation. This luminal acidity is known to regulate cytosolic-side fu...
Battery-free nano-sensors could pave the way for next-generation wearables
Nano-sensors that work without batteries or wires could pave the way for more comfortable, less obtrusive sleep and health care monitoring at home, according to...
