Phys.org / Extinct bovine species discovered in Siberia reveals lost relative of yaks
DNA analyses of ancient remains have revealed a previously unknown extinct bovine species that inhabited southern Siberia during and even before the last ice age. The extinct species was related to modern yaks but followed ...
Phys.org / Modern forensics reveals human sacrifice in ancient Egypt's royal burials
Over 500 years before the building of the Great Pyramid in Egypt, First Dynasty kings were buried in a tomb surrounded by many burials of household officials and artisans—many of which seem to have taken place at the same ...
Phys.org / Quantum systems never quite forget where they came from
Even the most chaotic quantum systems keep a permanent mark of their own past—a "quantum birthmark"—that never fades. Researchers from Tampere University, Harvard University and TU Dresden discovered the feature in their ...
Phys.org / Atomic motion could help push solar cells beyond conventional limits
The bulk photovoltaic effect (BPVE), a photoelectric effect that generates photocurrent without a p–n junction, can persist even when a material's average crystal structure remains centrosymmetric, a study from Institute ...
Phys.org / Forests are dying along North Carolina's coast—and it's speeding up
A new study finds that coastal forest loss in North Carolina's Albemarle-Pamlico Peninsula began accelerating after 2010 and may still be speeding up. The study also found that North Carolina lost more than 20% of its coastal ...
Phys.org / Lipid signals help cells seal the damage from bacterial attacks, researchers discover
Epithelial cells form the body's frontline barriers, helping keep microbes, toxins and other harmful substances out. Yet these protective cells are constantly exposed to threats, including microbial infections. Some bacteria ...
Phys.org / What a locust can teach us about how neuromodulators alter odor processing
When you walk into a bakery and smell fresh cookies, the enticing smell draws you in. After you eat a handful of cookies, though, the same smell likely doesn't send you back for more. Researchers in the McKelvey School of ...
Phys.org / Florida Keys heat wave reveals nearly fourfold death risk for diseased coral
Disease and heat pose a deadly combination for coral reefs, according to a new University of Georgia study published in the journal Coral Reefs.
Phys.org / Heat-induced nanoscale structures unlock electromechanical properties in ceramics
Scientists have developed a new way to make ceramic materials that can better withstand extreme heat and continue performing reliably in sensors and actuators. The approach creates tiny structures throughout the material ...
Phys.org / Pollen study reveals the hidden history of grasses
Scientists used machine learning and super-resolution microscopy to overcome a challenge that has stymied research into the natural history of grasses for decades. Their method allowed them to detect subtle differences among ...
Phys.org / Sharks' inner ears reveal surprising diversity that may reflect evolution more than environment
A new study of shark anatomy suggests the shape of their inner ears is far more variable than expected, and this variation could have more to do with their evolutionary history than where they live or what they eat.
Phys.org / 'Flying rivers' above South America form drainage networks resembling those on land
Water does not flow only through rivers on the ground. Vast quantities of water also move through the atmosphere, carried by winds from oceans and land before eventually falling as precipitation hundreds or even thousands ...
