Medical Xpress / New COVID 'Cicada' variant is spreading—what experts want you to know
Another new COVID variant is starting to spread. Health officials say the variant—known as BA.3.2 or "Cicada"—has been quietly circulating for years but is now being detected more often in the United States and around the ...
Phys.org / Combining algae and oyster shells for biodiesel born in the bayou
Biodiesel is a renewable fuel and offers a sustainable and potentially carbon-neutral alternative to petroleum products. Yet production costs remain a hurdle to its widespread use. Now, researchers have developed an inexpensive ...
Phys.org / Electric current stabilizes spins at unstable points for new types of computing
A research team has discovered a new way to control tiny magnetic properties inside materials using electric current, which could possibly pave the way for new types of computing technologies. The work is based on spintronics, ...
Medical Xpress / Can a new heart health metric identify fracture risk in postmenopausal women? Study finds link
Postmenopausal women face a high risk of bone fractures. Due to declines in estrogen levels, which can lead to an increased risk of osteoporosis, even a low-impact fall can result in a serious hip, back, or wrist injury. ...
Phys.org / The sea beneath Arctic and Antarctic ice holds many secrets. These scientists dive deep to find out
As bubbles rippled across the frigid Finnish lake, diver Daan Jacobs emerged from a hole carved out of the thick, crackling ice.
Tech Xplore / A robotic hand without motors? How a sub-second shape-shifting actuator could work
While space structures and robotic arms require lightweight actuation devices capable of repetitive movement, conventional motor-based systems face limitations due to their heavy weight and complex structures. A KAIST research ...
Phys.org / Motivations behind violent extremism uncovered in new global study
New research from the University of St Andrews has revealed that human readiness for intergroup violence is not a single or unified mindset. Published in the Proceedings of the National Academy of Sciences, the new study, ...
Phys.org / First quantum oscillations observed in gallium nitride holes
Gallium nitride, a semiconductor that can operate at high voltages, temperatures, and frequencies, has enabled technologies from LED lighting to high-power electronics. Now Cornell researchers have observed a quantum property ...
Tech Xplore / LLMs and creativity: AI responses show less variety than human ones
Can using a large language model (LLM) make a person more creative? Prior work has shown that using LLMs can make creative outputs more homogeneous, but this homogenization could stem from the specific LLM used or from widespread ...
Phys.org / All 5 fundamental units of life's genetic code were just discovered in an asteroid sample
A new study reveals all five fundamental nucleobases—the molecular "letters" of life—have been detected in samples from the asteroid Ryugu.
Phys.org / Organocatalytic strategy provides a metal-free route to antiviral candidates
A research team led by Prof. Sun Jianwei has achieved an advancement in organic synthesis and medicinal chemistry by developing an air-stable chiral phosphine-catalyzed enantioselective approach to synthesize enantioenriched ...
Phys.org / New lipid nanoparticle design improves precision of mRNA vaccine delivery
Penn Engineers have redesigned a key component of lipid nanoparticles (LNPs), the delivery vehicles behind mRNA vaccines, to steer the particles toward lymph nodes while reducing off-target delivery to the liver. The advance ...
