Medical Xpress / Hidden cell network offers new clues to intestinal healing and disease
Your intestine completely rebuilds its inner lining every few days—one of the fastest renewal processes in the human body. Scientists have now discovered that this extraordinary feat is accompanied by a hidden network of ...
Tech Xplore / Hybrid-electric aircraft clears 30,000 feet for first time in test flights
An aircraft powered by a megawatt-class hybrid-electric engine developed in collaboration with NASA and built by GE Aerospace, demonstrated flight of an innovation that can inform new generations of fuel-saving aircraft power ...
Phys.org / Ancestral variation, not new mutations, may impact survival of species facing climate change
Research co-authored by an Oklahoma Museum of Natural History curator, her graduate student and an international team of scientists has shed new light on the evolutionary "toolkit" animals use to survive environmental change.
Tech Xplore / Programmable metasurface turns keyboard commands into dynamic holograms in milliseconds
Metasurfaces are ultrathin optical components engineered with arrays of nanoscale structures that can control light in ways that are difficult for conventional optics. Unlike traditional optical components, which typically ...
Medical Xpress / Researchers uncover 'hidden key' to immunotherapy for intractable brain tumors
Researchers have uncovered a clue to why immune checkpoint inhibitors—cancer therapies that release the immune "brakes" exploited by tumors to evade attack—show limited efficacy in some brain tumors. A KAIST research team ...
Medical Xpress / Aspirin matches costlier blood thinners after hip and knee replacement surgery, major trial finds
Joint replacements are among the most common surgeries worldwide, and preventing blood clots is critical to recovery. A Dalhousie-led study published this month—one of the most robust of its kind to date—found that a straightforward ...
Phys.org / A century-old stellar mystery may finally have an explanation
For more than a century, astronomers have puzzled over a strange discrepancy in the historical record. Theta Eridani, a modest star in the constellation Eridanus, is the third-brightest star in its constellation, with a magnitude ...
Phys.org / Rare sighting reveals Arctic bobtail squid and egg masses in subzero Greenland fjord
Marine biologists have observed the Arctic bobtail squid in its natural habitat in the North Atlantic Ocean for the first time, including the rare discovery of a mature female with eggs. Dr Paige Maroni, from The University ...
Phys.org / What explains gender pay gaps in academia?
Gender pay gaps in academia are well documented. The harder question is why they persist. A new study published in the Proceedings of the National Academy of Sciences tested several leading answers to that question.
Tech Xplore / Mechanical engineers develop buttons that rise with light
No wires. No actuators. Shine light on the metal surface, and it rises like a button. KAIST researchers have developed a metal structure that changes shape using light, without any light-absorbing coating. This technology ...
Phys.org / Arctic winter sea ice returns to significant decline, ending the temporary slowdown
New analysis shows that a "pause" in Arctic winter sea ice decline seen in the early 2020s has ended following record lows in 2025 and early 2026. The study, led by the University of Southampton in collaboration with the ...
Phys.org / Floating igloo leaves France for polar exploration mission
A floating research station resembling a giant aluminum igloo on Sunday set out from France to begin a long-term mission in the Arctic that will see it drift with the polar ice in one of the most hostile environments.
