Medical Xpress / Redo mitral valve surgery outperforms transcatheter option
A new multicenter study published in The Annals of Thoracic Surgery finds that reoperative surgical mitral valve replacement (rSMVR) is associated with significantly better long-term survival compared to transcatheter mitral ...
Medical Xpress / Your liver is hiding a shifting cellular map, and diet can rapidly redraw its internal landscape
As we go about our day, the trillions of cells in our bodies run like well-oiled machines: continually sensing what's happening around them and making modifications to keep us humming along. Like adjusting a gear in a car ...
Medical Xpress / Want to reduce your risk of dementia? Pick up an instrument or take a foreign trip, say researchers
Playing the piano, foreign travel and socializing with friends are among the most powerful ways to reduce the risk of developing dementia, according to new research from Trinity College Dublin.
Phys.org / US climate sees decline in both hot and cold extreme temperatures since 1899, researchers claim
A comprehensive new study extending the U.S. Historical Climatology Network (USHCN) record back to 1899 finds that both hot and cold temperature extremes across the contiguous United States have declined over the past 127 ...
Phys.org / How Bruce the half‑beak kea weaponized his disability to become the alpha bird
Bruce the kea is missing his entire upper beak. Yet he is the alpha bird of his circus (the apt collective noun for a group of New Zealand's famously playful alpine parrots).
Medical Xpress / B cells that fight infections may also boost muscle performance during exercise
B cells are white blood cells that form a core part of the body's adaptive immune system, enabling it to recognize specific infections, remember them, and mount a targeted response by producing antibodies. A recent study ...
Phys.org / Put a nanodiamond under intense pressure and it becomes flexible
Diamond is among the hardest naturally occurring substances on Earth, but if you shrink it down to the nanoscale, it is surprisingly elastic. And that could be useful for a host of applications such as quantum computing. ...
Phys.org / Breakthrough sulfur polymer kills dangerous fungi and bacteria while sparing human and plant cells
Antimicrobial resistance is becoming a global burden in human health and food production, so affordable new materials are needed to overcome this growing problem. To answer the call, a multidisciplinary research team led ...
Phys.org / CHIME tracks a hyperactive repeating fast radio burst source
Using the Canadian Hydrogen Intensity Mapping Experiment (CHIME), an international team of astronomers has performed radio observations of FRB 20220912A—a highly active source of repeating fast radio bursts. Results of the ...
Medical Xpress / AI can use a photo of the eye to estimate retinal age, flag risk for major diseases
There may be some truth to the saying "the eyes are the window to the soul." Age-related changes are reflected in the retina, the light-sensitive tissue at the back of the eye. Recent research shows that a photo of the retina ...
Phys.org / The edge of the Milky Way's star-forming disk revealed
How far the Milky Way's disk extends has long been difficult to define—it doesn't end sharply, but fades away gradually at its outer edges. Now, for the first time, an international team of astronomers has identified the ...
Phys.org / Alternating atomic layers enable rare electron pairing mechanism in new unconventional superconductor
Superconductors, materials that can conduct electricity with a resistance of zero, have proved to be highly promising for the development of quantum technologies, medical imaging devices, particle accelerators and other advanced ...
