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 / 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 / Rising seas are inundating US coastal wetlands, putting many on track to become open water
Along the three coasts of the contiguous United States, a silent race unfolds. Fueled by climate change, sea levels rise faster than at any time in recent geologic history. Meanwhile, coastal wetlands cling to a slim lead, ...
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 / 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 / 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 / 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 / Seven new diamond frog species reveal Madagascar's hidden amphibian diversity
An international team of scientists has described seven new species of Madagascar's elusive diamond frogs (Rhombophryne), revealing that one of the island's most mysterious groups of amphibians is even more diverse than previously ...
Phys.org / Life speaks one universal language to activate genes: It speaks many more to silence them
The signals that cells use to switch genes on have remained almost unchanged across 2 billion years of evolution, but the ones used to switch genes off vary dramatically from one branch of life to another, according to a ...
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 / Pluto's hazy atmosphere may be collapsing as it moves farther from the sun
Pluto is on an icy march away from the sun. In 2114, it will turn back, but until then, its elliptical orbit will carry it to colder and darker parts of the outer solar system. This is Pluto's first time entering the outer ...
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 ...
