Medical Xpress / Researchers develop first synthetic mitral valve model to replicate the heart's natural mechanics
Researchers at RCSI University of Medicine and Health Sciences have developed an artificial model of the mitral heart valve that faithfully mimics the valve's complex mechanical behavior in the human heart. The study could ...
Tech Xplore / Researchers discover hidden chip threats and a way to stop them
Every day, billions of people trust computer chips to protect their most sensitive information, ranging from banking passwords to national security secrets. But what if those chips were secretly compromised before they even ...
Phys.org / Astronomers discover the earliest known flickering quasar
A supermassive black hole lies at the heart of every galaxy, including the Milky Way. When a black hole is active, it pulls material in as a whirlpool of high-temperature gas and dust. As this cosmic material piles up and ...
Science X / Hidden immune-microbiome link may explain lung disease's mysterious origin
Over the last few years, people have become quite aware of the gut microbiome and its impact on our overall health. Microbiome, however, isn't exclusive to the gut, as a host of bacteria also reside inside our lungs, and ...
Phys.org / Hardy ice plant's optical innovation inspires reflective design possibilities
Nature is filled with remarkable visual phenomena created by microscopic surface structures that interact with light in fascinating ways. The iridescent wings of butterflies, the shimmering feathers of birds and the glossy ...
Medical Xpress / Remote monitoring alone fails to reduce readmissions for sepsis, trial finds
Remote monitoring isn't a panacea for reducing readmissions across all conditions—and for some patients, clinicians should proceed with caution, clinical trial results published in JAMA Network Open suggest.
Tech Xplore / Anthropic pledges $200 million to research AI's economic impact as CEO suggests job loss solutions
Anthropic on Wednesday joined growing calls for the artificial intelligence industry to find ways to cushion people from the technology's disruptions, announcing an initial $200 million investment to research AI's impact ...
Phys.org / Q&A: Combating antibiotic resistance with nanotechnology, robotics and AI
Aeron Tynes Hammack, a physicist by training and currently interim facility director of the Nanofabrication Facility at the Molecular Foundry, likes to work with nanoscale objects to better understand the world and solve ...
Phys.org / Why are sloths slow? It's in their DNA
Sloths are the slowest mammals on the planet, but living in dense jungles has made them notoriously difficult to study. For the first time, scientists have now sequenced and analyzed the two-toed sloth genome and revealed ...
Phys.org / MeerKAT reveals three electron acceleration sites in one solar flare
Solar flares are the most explosive energy-release events in the solar corona, leading to intense particle acceleration, plasma heating and bulk plasma motions on short timescales. Core questions during solar flares remain ...
Phys.org / New warning system forecasts wildlife heat risk up to nine months ahead
An international group of scientists led by Josep M. Serra-Diaz, researcher at the Botanical Institute of Barcelona (IBB, CSIC-MCNB), has developed the first global early warning system capable of forecasting when and where ...
Phys.org / Report: ICE surges have triggered massive job losses—including among Americans
Since January 2025, the Trump administration has ramped up immigration enforcement. A key rationale for the policy is that it will open up jobs for Americans by reducing competition from undocumented immigrants.
