Phys.org / Quasi-liquid layer controls growth mechanisms of ice-like materials
Clathrate hydrates are crystalline structures formed at the bottom of seafloors, created by water molecules trapping methane, carbon dioxide or other molecules. While these materials are underutilized in technology, a University ...
Phys.org / Why student samples can mislead: Higher education may shift values toward Western norms
A new study published in Nature Communications finds that worldwide, people with higher levels of education are more culturally similar to those in Canada, the U.S., U.K., and other Anglo, industrialized countries and countries ...
Tech Xplore / Perovskite solar cells achieve over 25% efficiency and long lifespan simultaneously
A KAIST research team has solved the "solar cell dilemma," in which increasing efficiency shortens lifespan, while extending lifespan lowers efficiency. The team developed a technology to precisely control the internal structure ...
Tech Xplore / At 50, Apple confronts its next big challenge: AI
Apple celebrates its 50th anniversary as artificial intelligence challenges the Silicon Valley legend to prove it can deliver yet another culture-changing innovation.
Medical Xpress / After allogeneic transplant, VIC-1911 regimen shows low severe GVHD and no relapse
Results of a Phase I clinical trial show that patients who undergo a blood stem cell transplant involving a donor have a lower risk of relapse and lower rates of graft-versus-host disease when they receive the targeted therapy ...
Tech Xplore / AI is giving bad advice to flatter its users, says new study on dangers of overly agreeable chatbots
Artificial intelligence chatbots are so prone to flattering and validating their human users that they are giving bad advice that can damage relationships and reinforce harmful behaviors, according to a new study that explores ...
Phys.org / Tale of the lava heron: Student describes new Galapagos species
The Galapagos Islands are famous for the discoveries that shaped Charles Darwin's theory of evolution. Now an SFSU graduate has added one more: Ezra Mendales (M.S., '23) describes a new species as part of his master's thesis. ...
Phys.org / The hidden cost of sperm storage: Ejaculates found to deteriorate across the animal kingdom
Current World Health Organization (WHO) guidelines typically recommend two to seven days of abstinence before taking semen samples or assisted reproduction. However, a new study led by Oxford University researchers suggests ...
Phys.org / Moby Dick 'ship sinking' sperm whales caught headbutting on camera
New research from the University of St Andrews reports sperm whales headbutting one another. The behavior was captured on film and described scientifically for the first time, confirming accounts by 19th century mariners ...
Phys.org / Discovery of genetic switch could help turn rice into a perennial crop
Rice is a vital crop that feeds more than half of the world's population. In the wild, many rice species are perennials that live for several years, but the varieties we eat today are typically annuals that must be replanted ...
Phys.org / X-ray lasers enable the discovery of a critical point in water
Using X-ray lasers, researchers at Stockholm University have been able to determine the existence of a critical point in supercooled water at around -63 °C and 1,000 atmospheres. Ordinary water at higher temperatures and ...
Tech Xplore / Scheimpflug cameras may extend LiDAR-like sensing from 6 m to 4 km
An optical principle discovered more than a century ago may soon find new applications in such areas as monitoring atmospheric turbulence, tracking airborne objects, and mapping the environment, thanks to researchers at the ...
