Phys.org / How the humble silkworm could help us discover new anti-aging treatments
When scientists want to study aging and how to slow it down, they often turn to microscopic worms or lab mice among other models. The former are too different from humans, while the latter are expensive and take too long ...
Tech Xplore / AI 'blind spot' could allow attackers to hijack self-driving vehicles
A newly discovered vulnerability could allow cybercriminals to silently hijack the artificial intelligence (AI) systems in self-driving cars, raising concerns about the security of autonomous systems increasingly used on ...
Dialog / Natural selection can work at many levels, from molecules to ecosystems
When most people think about natural selection, they imagine individuals competing with one another: The fastest animal escapes predators, the strongest plant produces more seeds, and the most resistant bacteria better survive ...
Tech Xplore / Ultrafast 3D printing method creates complex objects in under a second
High-speed 3D printing has just gotten a lot faster. Researchers from Tsinghua University in China have developed a new high-speed printing technology capable of creating complex millimeter-scale objects in just 0.6 seconds. ...
Phys.org / How choices made by crowds in a train station are guided by strangers
In crowds, most people are strangers to you, and everyone else for that matter. However, until now, the effect of stranger-to-stranger interactions on the choices people make in crowds has not been properly examined. Ziqi ...
Phys.org / Impact-formed glass provides evidence of cosmic collision in Brazil about 6 million years ago
For the first time in Brazil, researchers have identified a field of tektites. These are natural glasses formed by the high-energy impact of extraterrestrial bodies against Earth's surface. These structures, named geraisites ...
Medical Xpress / MRI antenna can boost image quality and shorten scan times—without changing existing machines
Magnetic resonance imaging (MRI) is one of medicine's most powerful diagnostic tools. But certain tissues deep inside the body—including brain regions and delicate structures of the eye and orbit that are of particular ...
Medical Xpress / Newly found immune cells link strep throat to psoriasis
A common strep throat infection can trigger guttate psoriasis by altering the behavior of key immune cells, according to a new study from Karolinska Institutet published in eBioMedicine. The findings suggest how an infection ...
Phys.org / Phonon lasers unlock ultrabroadband acoustic frequency combs
Acoustic frequency combs organize sound or mechanical vibrations into a series of evenly spaced frequencies, much like the teeth on a comb. They are the acoustic counterparts of optical frequency combs, which consist of equally ...
Phys.org / Quantum trembling: Why there are no truly flat molecules
Traditional chemistry textbooks present a tidy picture: Atoms in molecules occupy fixed positions, connected by rigid rods. A molecule such as formic acid (methanoic acid, HCOOH) is imagined as two-dimensional—flat as a ...
Phys.org / Massive ceramics haul from a 14th-century shipwreck reveals Singapore's trading past
Singapore was a thriving trading hub hundreds of years before popular narratives depicted it as a quiet fishing village, according to a study of the cargo of a centuries-old shipwreck. Sometime during the middle of the 14th ...
Medical Xpress / Why chronic pain lasts longer in women: Immune cells offer clues
Chronic pain lasts longer for women than men, and new research suggests differences in hormone-regulated immune cells, called monocytes, may help explain why.
