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 / 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 / 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 / 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 / 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 / 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 / Underground fungal networks come into 3D view without disturbing plant roots
Symbioses between plants and fungi are essential for most plants. Fungal structures known as mycorrhizae extend the area from which plants can draw water and nutrients from the soil. In return, plants supply the fungi with ...
Phys.org / Why we overestimate the positive impact of our actions on the climate
Why is recycling waste or switching off the lights sometimes perceived as more effective for the climate than giving up air travel? A team from the University of Geneva (UNIGE) surveyed nearly 3,000 people and identified ...
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 ...
Phys.org / Discarded rice husks capture toxic dyes, offering a reusable water filter
Rice is the most-eaten food on the planet, and its discarded outer husk results in some 300 billion pounds of waste per year. FIU chemistry researcher Islam Ibrahim Hussein says the inedible castoffs could be the key to cleaner ...
Phys.org / Pixel patterns harness diffraction for faster, more accurate nanoscale 3D printing
Researchers at the George W. Woodruff School of Mechanical Engineering have developed a new approach to nanoscale 3D printing that improves both speed and fidelity, overcoming a challenge that has limited the technology's ...
