Phys.org / Meet Crocodylus lucivenator, a 12- to 15-foot predator that hunted iconic Lucy's species
More than 3 million years ago, when our ancient ancestors embodied by the iconic Lucy were roaming the African landscape, they would have feared a big, bad crocodile with a prominent lump on its head, patiently lurking in ...
Phys.org / Nocturnal ants use lunar compass and sophisticated calculations to travel at night
It's well known that many animals, including migratory birds, butterflies, and even fish, use the sun for navigational purposes. Nocturnal animals are dealt a more difficult hand, however, as the moon's path is far more variable. ...
Phys.org / Bright pink insect stands out to blend in, scientists say
A tropical insect has been found to change color from vivid hot pink to green within a fortnight, which scientists believe may mimic the young leaves of rainforest plants. The findings, published this week in the journal ...
Phys.org / Hydrogen atmosphere could keep exomoons habitable for billions of years
Liquid water is considered essential for life. Surprisingly, however, stable conditions that are conducive to life could exist far from any sun. A research team from the Excellence Cluster ORIGINS at LMU and the Max Planck ...
Phys.org / New exoplanet survey method finds high rates of closely orbiting planets
Up until now, exoplanet surveys have mostly focused on nearby, bright stars that are sun-like or are red dwarfs, which are known to frequently host planets. While astronomers have discovered thousands of planets this way, ...
Medical Xpress / Pregnancy changes the brain, and we are only beginning to understand how and why
Millions of women go through pregnancy every year, yet science has only just begun to look at what it does to the brain—the organ undergoing perhaps the most remarkable transformation. Over the past decade, a small group ...
Phys.org / Thorny issue plaguing lithium-ion batteries laid bare in new study
Lithium dendrites, i.e. tiny crystalline thorns that grow off of lithium-ion battery anodes during charging, have been a persistent challenge for the world's most widely used form of energy storage. "Dendrites can penetrate ...
Tech Xplore / Who covers AI business blunders? Some insurers cautiously step up
As more businesses trust artificial intelligence "agents" to independently grow their revenues, some insurance firms are stepping in to cover any mistakes—while others are steering clear.
Medical Xpress / What pet cats can tell us about human cancer
They live in our houses, drink our water and even sleep in our beds. Cats have become an integral part of many households and share much of our lives. They also share much of their biology with humans. Pet cats get cancer ...
Phys.org / Decades-old problem in classical geometry solved: First compact pair of bonnets found
For over 150 years, a rule of thumb dating back to the French mathematician Pierre Ossian Bonnet has been accepted in surface theory: If the metric and mean curvature of a compact surface are known at every point, then the ...
Tech Xplore / How an acid found in grapes could help recycle battery metals
Cobalt and nickel are vital components for batteries, superalloys and catalysts, used in technologies ranging from smartphones to jet engines. But when it comes to recycling, they are notoriously difficult to separate because ...
Phys.org / Avalanche risks are rising—researchers say governance must rise with them
The findings of a new paper show governance and preparedness rather than hazard magnitude determine whether avalanches become mass-casualty events. With large ice-rock avalanches growing in frequency as steep slopes in the ...
