Phys.org / Caddisfly silk gene evolves quickly without losing adhesive power
Caddisflies are among nature's master underwater builders, capable of spinning sticky silk that they use to form protective cases and webs in freshwater streams. Scientists like the University of Utah's Russell Stewart have ...
Medical Xpress / Eye movements reveal personal 'fingerprints' as people explore unfamiliar scenes
Walk into a crowded coffee shop, and what catches your eye as you take in the scene could say as much about you as the spirals on your fingertips or the mutations in your DNA. Eye movements are so unique, in fact, that they ...
Phys.org / Unraveling the glass-like nature of epithelial tissues
In a new study, researchers at the Indian Institute of Science (IISc) have resolved a longstanding mystery by showing how epithelial tissues exhibit slow-moving, glass-like behavior despite their fast-paced biological activity. ...
Tech Xplore / Apple files lawsuit accusing ChatGPT maker OpenAI of stealing trade secrets
Apple on Friday accused OpenAI of stealing trade secrets as it seeks to build its own hardware for ChatGPT, a major rupture in a partnership between the iPhone maker and the artificial intelligence company.
Phys.org / Researchers break a fundamental rule to create a new concept: Heat that can be directed and 'programmed'
Normally, a material absorbs and emits heat in a linked way: A surface that absorbs heat well at a certain wavelength and direction will also emit heat in the same way. This fundamental relationship, known as reciprocity, ...
Tech Xplore / AI memory bottleneck may ease as ultrathin chip stacks quadruple high-bandwidth memory density
A Korean research team has developed a technology that enables the stable stacking of more than 10 ultrathin semiconductor chips, each only one-fifth the thickness of a human hair. A research team successfully achieved an ...
Phys.org / Astronomers dig deep to find tiny dangerous space debris
In a new study, published in the Journal of the Astronautical Sciences, Warwick researchers led an international effort to uncover some of the faintest debris in geosynchronous orbit ever observed, finding fragments as small ...
Phys.org / Steering light in a flash: New chip redirects light beams in less than a trillionth of a second
Light can carry enormous amounts of information at extreme speeds, making photonic technologies promising for the development of faster communications, more powerful computing systems and more sensitive sensors. But for light ...
Phys.org / X-pinch plasma achieves radial proton acceleration for crisp imaging
Plasma pinches: From pursuits of nuclear fusion to an attractive point source of accelerated protons for proton radiography.
Phys.org / Space sensor could spot hidden nuclear weapons in orbit with 99% accuracy
In 2024, a U.S. government official warned that Russia could be developing a new satellite designed to carry nuclear weapons into space. The statement followed the launch of a suspicious Russian satellite into low-Earth orbit ...
Phys.org / Quantum computers model nine fusion fuel material configurations for first time
A team of scientists from Oak Ridge National Laboratory, Cleveland Clinic and IBM has calculated nine molecular configurations of a promising material to produce fuel for fusion energy—the first known instance of such computations ...
Medical Xpress / Surgeons use teleoperated humanoid robots to perform live surgery—a world first
For the first time, two teleoperated humanoid robots have been used to complete two surgeries during a preclinical trial, researchers report in the July 8 issue of the journal Nature. The work is the result of a collaboration ...
