Phys.org / A fake spider at the tip of this snake's tail helps it lure birds: Scientists get their first look inside it
Lots of animals use mimicry to survive. Some copy the appearance of threatening predators, and others have evolved to resemble plants or rocks so they can blend into the background and avoid being attacked. But a viper from ...
Phys.org / Ultrathin silicon structures can tune mid-IR light in billionths of a second
Light in the mid-infrared (mid-IR) portion of the electromagnetic spectrum plays a key role in modern sensing. Because molecules interact with this kind of light in specific ways, researchers use technologies like mid-IR ...
Phys.org / A 66.5-million-year-old trackway captures adult T. rex at walking pace
Scientists from the Denver Museum of Nature & Science and Liverpool John Moores University in England have discovered the first adult T. rex trackway, providing insights into how this emblematic predator moved. The findings ...
Medical Xpress / Stress hormone timing creates a different kind of obesity, study suggests
Obesity caused by disrupted stress-hormone rhythms is metabolically very different from obesity caused by a high-fat diet, according to a new preclinical study by Weill Cornell Medicine investigators. The researchers found ...
Phys.org / 'Peculiar' new species of Jurassic squid found in Wyoming
A "peculiar" new species of Jurassic squid-like animal has been unearthed in Wyoming, U.S., following the discovery of two exceptionally rare fossils dating to around 160 million years ago.
Phys.org / Chinese cave traces Denisovan hunting and adaptation across 120,000 years
An ancient cave in southwestern China has revealed new evidence about how Denisovans—an ancient human relative—lived, survived and adapted over more than 100,000 years.
Phys.org / A cellular threshold can determine whether herpesvirus becomes active or lies dormant
During the COVID-19 pandemic, we wore masks and kept 2 meters (6.6 feet) apart in an effort to reduce the spread of the tiny droplets we release into the air with every breath, conversation or cough. The main goal was to ...
Tech Xplore / Brain-inspired computing: Using noise to regulate information flow in neural networks
Researchers have developed a learning mechanism that uses the natural variability of neural activity—often dismissed as random "noise"—to understand how synapses buried deep inside brain networks—or brain-inspired devices—can ...
Phys.org / Unaccounted climate feedback loops may amplify warming by 20–30% this century, but cutting emissions will reduce risks
New research shows that warming-induced emissions—greenhouse gas emissions from natural sources driven by rising temperatures—could amplify global warming by approximately 20%–30% and add an estimated 0.2°C–0.4°C of warming ...
Phys.org / Water isotopes reveal early drought signals in Central Amazon rainfall
The historic droughts of 2023 and 2024 in the Amazon reduced river flows and altered the region's rainfall composition. Daily monitoring in Manaus, the capital of the Brazilian state of Amazonas, revealed these changes through ...
Tech Xplore / In a shift, OpenAI calls for US rules on powerful AI
OpenAI is calling for binding safety requirements on the most powerful artificial intelligence systems, a reversal for a company that has resisted calls for regulation.
Phys.org / Could quantum protocols make electronic voting more secure?
Electronic voting, the use of electronic systems to cast, record or count votes, could potentially simplify the process of electing new political leaders or other representatives. While some countries have already started ...
