Phys.org / Camera-tagged Adélie penguins caught eating sea snails in East Antarctica
There are many poorly understood links in the food web, often referred to as trophic relationships. Out in East Antarctica, a previously unconfirmed link between sea snails and Adélie penguins might reveal more than meets ...
Phys.org / From teeth to thorns: Coincidences shape the universal form of nature's pointed tips
We thought it was evolution, but an experiment with pencils shows that tips like teeth and thorns may owe their rounded shape to mechanical wear. Most of us have been stung by a bee, bitten by an animal, or scratched by a ...
Phys.org / Highway widening may be heating cities faster; here's what could curb it
U.S. cities are rapidly becoming urban heat islands, where these cities are significantly warmer than their surrounding area. Vast expanses of asphalt and concrete trap heat, while large, densely packed buildings disrupt ...
Phys.org / Scientists discover f-block metals yield new oxygen-binding chemistry
Iron and oxygen bind together throughout the body. Most famously, iron binds dioxygen, or two oxygens paired with each other, in hemoglobin that transports oxygen through blood. But iron-oxo compounds, as they're called, ...
Phys.org / Tropical trees are more neighborly than trees further from the equator, study finds
Tropical trees are better neighbors than trees in temperate forests, according to a study published in the journal Nature by researchers from 29 different institutions including the Smithsonian Tropical Research Institute ...
Phys.org / How bromoform wrecks ozone: Ultrafast 'roaming' step captured in 150 femtoseconds
The halomethane compound bromoform (CHBr3) has devastating effects on the ozone layer. In the upper layers of the atmosphere, bromoform reacts with UV radiation, releasing bromine molecules which destroy ozone molecules. ...
Medical Xpress / How a key memory center in the brain responds to the unexpected
The hippocampus is a crucial part of the brain that plays a role in memory and learning, especially in remembering directions and locations. New research from the University of Chicago shows how this small, curved structure ...
Phys.org / AI chips could get faster with 30-nanometer embedded memory that cuts data shuttling
When we watch videos or ask AI questions, enormous amounts of data are constantly moving inside computers. In particular, data centers that support AI must process and transfer vast amounts of data at very high speeds. However, ...
Tech Xplore / After Anthropic's Mythos AI uncovers thousands of zero-day bugs, top US officials huddle with bank CEOs
The heads of America's biggest banks met this week with Federal Reserve Chairman Jerome Powell and Treasury Secretary Scott Bessent to weigh the security implications of a new artificial intelligence system developed by Anthropic, ...
Medical Xpress / Hippocampal pathways once thought separate converge to integrate 'where' and 'why' in reward processing
New research from the University of Maryland, Baltimore County (UMBC) reveals how two different parts of the brain's memory center team up in a key reward region to help mice—and likely humans—combine memories of places and ...
Medical Xpress / Epigenetic changes at birth are associated with an infant's microbiome and neurodevelopment
The gut microbiome and epigenetics—molecular switches that turn genes on or off—are intertwined, and both contribute to neurodevelopment, finds a study published in Cell Press Blue. The researchers showed that epigenetic ...
Phys.org / Rare Roman paint 'recipe' uncovered in Cartagena murals makes smart use of costly cinnabar
Roman painters commissioned at the end of the 1st century to decorate the walls of the Domus of Salvius in present-day Cartagena could hardly have imagined that their technical expertise would still attract attention twenty ...
