Phys.org / Radio scans find no alien tech from the latest interstellar comet
The group leading the charge in the search for extraterrestrial life has given the all clear: An interstellar comet looks to be completely natural and free of any alien tech.
Medical Xpress / An intranasal flu vaccine approved two decades ago may have underappreciated immune benefits
For decades, influenza vaccines have been judged largely by the antibodies they generate in the bloodstream, a measure that has remained the gold standard since the first flu immunizations were administered in the 1940s.
Medical Xpress / Most people seeking a kidney transplant in the US never reach the waitlist
Nearly half of Americans with kidney failure who are referred for transplantation never begin the process required to be considered for a new organ, a new study shows, while less than a fifth actually complete the assessment ...
Tech Xplore / Floating solar panels keep working through icy Canadian winters
To accommodate the increasing demand for clean energy, researchers have been developing floating solar panels for rivers, reservoirs and other waterways in recent years. While there is, of course, plenty of land for solar ...
Medical Xpress / Early life adversity leaves a lasting molecular imprint across the body, primate study reveals
The experiences we face early in life may leave their marks on our health in ways that echo across decades—and even across the entire body. A new study, published in the journal Science, examined a unique group of free-living ...
Phys.org / 15-atom iridium nanoclusters stay stable 20 hours, outperform commercial catalysts
An international research team from Tohoku University, Tokyo University of Science, Vanderbilt University and the University of Adelaide has discovered a novel, exceptionally simple method to precisely synthesize extremely ...
Phys.org / Bat rays employ a chemical cue to warn others of danger
Frightened bat rays produce a chemical cue to warn other rays of danger, a well-known anti-predator strategy for bony fish that has not been documented in cartilaginous fish until now. Oregon State University researchers ...
Phys.org / How H5N1 bird flu hid unrecognized for weeks in dairy cattle
When H5N1 bird flu first began infecting U.S. cattle in early 2024, diagnosis was elusive because, in cows, the disease looked completely different. Instead of affecting the lungs, as H5N1 does in other mammalian species, ...
Phys.org / Laser pulses set layered metals vibrating 1 trillion times per second, revealing electron-driven motion
How does light turn into motion within a metal? A team of researchers from European XFEL, the University of Potsdam and other participating institutions has shown that ultrashort optical laser pulses can trigger extremely ...
Phys.org / Northern permafrost switches from carbon sink to carbon source earlier than thought in models including deep soil carbon
The Arctic and northern high latitudes are warming about 2–4 times faster than the global average, allowing ancient permafrost to thaw and release stored carbon. These permafrost soils currently store roughly one-third of ...
Phys.org / Stressed-out soil bacteria adapt to environmental conditions
A new study from Caltech demonstrates that soil bacteria can adapt under stress, particularly when a key nutrient, phosphorus, is running low in their environment. The work is important for understanding the complex relationships ...
Phys.org / Mars life search gets boost as rover test distinguishes mirrored biosignature molecules
Billions of years ago, environmental conditions on Mars were significantly more hospitable than they are today. Our neighboring planet was likely warm, humid and surrounded by a dense atmosphere. Whether simple microorganisms ...
