Medical Xpress / Why COVID and flu hit older lungs harder: Aging tissue may bring on immune dysregulation
Older adults are much more likely to become seriously ill from flu or COVID because aging lung cells can drive excessive immune responses, according to a new study led by researchers at UC San Francisco. The findings enhance ...
Phys.org / Tiny LED design could power next-generation technology
From 3D movie screens to augmented-reality devices, many modern technologies rely on our ability to manipulate light. Doing so in a cost-effective and efficient way, however, is often a formidable task. In an article published ...
Medical Xpress / Common blood pressure drug can boost cancer treatment
In a new Dartmouth Cancer Center (DCC) study led by clinical researcher Tyler J. Curiel, MD, MPH, FACP, investigators found that the FDA-approved blood pressure drug telmisartan can significantly enhance the cancer-killing ...
Phys.org / New model finds complex earthquake patterns of the Phlegraean Fields near Naples
The Phlegraean Fields volcanic complex, located beneath the metropolitan area of Naples—a city of 900,000 inhabitants in Italy—has been rising increasingly since 2005, accompanied by a growing number of small earthquakes. ...
Phys.org / Unlocking the cell's 'gatekeeper': Researchers discover critical RNA quality-control factor, LENG8
How do cells ensure that the "blueprints" of genetic information-RNA are accurate and intact before they are exported from the nucleus to the cytoplasm for protein production? A study led by Professor Yongsheng Shi's team ...
Tech Xplore / Scheimpflug cameras may extend LiDAR-like sensing from 6 m to 4 km
An optical principle discovered more than a century ago may soon find new applications in such areas as monitoring atmospheric turbulence, tracking airborne objects, and mapping the environment, thanks to researchers at the ...
Phys.org / New synthetic origin of replication lets multiple plasmids coexist in one bacterial cell
"If it ain't broke, don't fix it," goes the old adage, which Rice University professor James Chappell completely ignored in a recent Nature Communications publication. In the study, Chappell describes an innovation in plasmids, ...
Phys.org / 'Near-misses' in particle accelerators can illuminate new physics, study finds
Particle accelerators reveal the heart of nuclear matter by smashing together atoms at close to the speed of light. The high-energy collisions produce a shower of subatomic fragments that scientists can then study to reconstruct ...
Phys.org / Why cells respond 'incorrectly' in old age
Some of the signs of aging in human cells originate in the cell nucleus, because the packaged form of DNA changes with age. This has now been demonstrated by PSI researchers. It means that older cells can no longer react ...
Tech Xplore / Molecular umbrella can protect solar cells by blocking ion migration
Perovskites are semiconducting materials that have rapidly transformed the field of optoelectronics, demonstrating outstanding performance in light-emitting diodes (LEDs) and photodiodes. For their unique properties, they ...
Phys.org / Agricultural soils exposed to controversial weedkiller may be unexpected breeding ground for hospital 'superbugs'
Each year, antimicrobial resistance (AMR) is responsible for an estimated 1.1 to 1.4 million deaths worldwide. Now, scientists have found evidence that the spread of AMR isn't always driven by bacteria evolving to resist ...
Tech Xplore / Fragmented phone use—not total screen time—is the main driver of information overload, study finds
Amid hot discussion on screen time, social media use and the impact of digital devices on our well-being, a seven-month study from Aalto University in Finland sheds new light on what overwhelms users the most—and the results ...
