Phys.org / Real-time fish interaction enlarges young guppy brains, while screen time falls short
Young guppies who were able to see and interact with live fish developed larger brains than guppies who only saw other fish on a screen. This is shown in a new study from Stockholm University, published in Biology Letters. ...
Phys.org / Overarming America: Game theory explores how fear and social pressure drive gun purchases
A Dartmouth College study is the first to map the interplay of personal choice and social networks that has led to the United States being one of the world's most heavily armed countries, with 120 firearms for every 100 people. ...
Phys.org / Half-ton early bovines roamed 4-million-year-old grasslands in Europe
The first large-sized bovines grew to up to half a ton 4 million years ago in the European Early Pliocene, an early step toward our modern diversity of large-bodied buffalo and cattle, according to a study published June ...
Phys.org / Ultrafast laser shrinks to chip scale, potentially lowering costs for diagnostics and atomic clocks
Ultrafast lasers emit pulses lasting only a few hundred femtoseconds (quadrillionths of a second). These flashes of light power applications from precision micromachining to eye surgery to optical frequency combs, the Nobel ...
Phys.org / Egypt fossils show modern ocean fish rose rapidly after dinosaur extinction
The extinction that ended the Age of Dinosaurs is best known for clearing the way for the Age of Mammals on land. Scientists have long suspected that the same catastrophe also transformed life in the seas, opening ecological ...
Phys.org / Out-of-plane ice bridges reveal new way to suppress frost spreading
A research team led by Professor Nenad Miljkovic in The Grainger College of Engineering at the University of Illinois Urbana-Champaign has published a breakthrough study in Nature Physics. The work reports the first experimental ...
Phys.org / Chip-scale 'acoustic atom' controls sound waves to imitate atomic energy levels and advance computing
For every action, there is an equal and opposite reaction. What goes up must come down. Physical laws like these govern all of the natural world—except for the tiny internal components of today's microprocessors, which operate ...
Phys.org / Armed with AI, study identifies prey from predator crunching sounds
Interactions between hard-shelled marine mollusks such as clams and snails and their predators play a critical but largely unseen role in shaping coastal ecosystems. These organisms help stabilize shorelines, filter water ...
Phys.org / SWOT satellite gets clearer ocean data after fix for hidden underwater wave interference
Florida State University research published in Science Advances demonstrates a new framework for predicting the motion of kilometer-scale underwater waves that complicate satellite readings of the ocean.
Phys.org / Printed manga may give the brain a storytelling advantage
A new study by researchers at the University of Tokyo explores whether reading manga on paper or on a tablet changes how the brain understands and remembers stories. Participants first read the opening half of a two-part ...
Phys.org / Portable UV spectrometer can detect air pollutants across 2.5 km with high precision
Birgitta Schultze-Bernhardt and her team at the Institute of Experimental Physics at Graz University of Technology (TU Graz) have developed a new type of UV dual-comb spectrometer that detects gaseous air pollutants with ...
Phys.org / 'BBQ sauce' phase may link little red dots to quasars
Everyone knows that finding the right sauce recipe can make or break a barbecue, but now astronomers are using BBQSORS (pronounced "barbecue sauce") as part of the recipe to explain quasars, some of the brightest objects ...
