Phys.org / Suspected heatstroke kills three lions at Japan zoo
Three lions from a Tokyo zoo have died from suspected heatstroke, and others are under treatment, a spokeswoman said Tuesday, with the big cats struggling with high humidity.
Phys.org / Marine microbes point to ancient seawater source beneath Antarctica's Blood Falls
Salty water flowing through Antarctica's Blood Falls contains a distinct community of marine-specific microorganisms, providing evidence that the brine system beneath the glacier has a marine origin, according to a paper ...
Phys.org / Bringing it all into focus—computational microscope captures 25.2 billion pixels per second across a wide field of view
When designing microscopes, optical engineers have long faced a trade-off between speed, field of view and resolution. But improving one of these properties typically comes at the expense of another. Now, a UC Berkeley–led ...
Phys.org / Mechanical shortcut' rapidly carries organic particles into the deep ocean
The processes that capture carbon from the atmosphere and store it on the seabed are crucial for climate balance. However, assessing these mechanisms is often complicated because it requires measurements ranging from the ...
Phys.org / Four labs find experimental differences can undermine AI catalyst predictions
To turn abundant carbon dioxide into valuable fuel, we need a fast and efficient way to determine which catalysts work best over the longest time. AI models have the potential to help guide catalyst selection, but as with ...
Phys.org / Geological evidence questions the role of Agulhas Leakage in Atlantic Ocean circulation
For decades, scientists have asserted that the leakage of warm, salty Indian Ocean water south of South Africa into the Atlantic is a major contributor to the Atlantic Meridional Overturning Circulation (AMOC), a component ...
Phys.org / Homo antecessor skull layers resemble modern humans and Neanderthals, fragments suggest
A new study provides quantitative data on cranial vault thickness in Homo antecessor, based on the analysis of three parietal fragments recovered from the Gran Dolina site in the Sierra de Atapuerca, Burgos, Spain.
Phys.org / Male sperm whales produce loudest communication sounds ever measured in any mammal
Deep in the world's oceans, large male sperm whales emit slow, low-frequency clicks with the highest source levels of any animal communication sounds. These slow clicks are not the echolocation clicks the whales use to locate ...
Phys.org / Forest floors reveal overlooked seed dispersers: Slugs, beetles and crabs spread viable seeds
A review led by the School of Biological Sciences at The University of Hong Kong (HKU) has revealed that tiny ground-dwelling invertebrates are overlooked but important seed dispersers, challenging the traditional focus on ...
Phys.org / New museum find shows nature can't stop inventing seahorses
At first glance, it looks exactly like a seahorse. It has the same horse-shaped head tilted down from the body, the same curled, grasping tail and, in the males, a fully enclosed pouch for brooding the young.
Phys.org / Stomach stone hypothesis sheds light on the evolution of dinosaur digestive systems
An international research team led by Assistant Professor Ryuji Takasaki of the Faculty of Biosphere-Geosphere Science at Okayama University of Science has published a paper proposing a new hypothesis on the evolutionary ...
Phys.org / AI models atom movement to predict solid-state reaction pathways, including impurities, in minutes
A research team at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has successfully demonstrated an AI modeling approach that accurately and rapidly predicts how reactions between solid materials ...
