Phys.org / Rescue mission is called off for NASA's aging Swift space telescope
The mission to save NASA's sinking Swift Observatory was called off Wednesday, dooming the telescope to a fiery reentry later this year.
Tech Xplore / Electronic skin improves temperature and pressure sensing for personalized prosthetics
An electronic skin with a sensing system that can detect pressure and temperature could someday help amputees gain feeling in their prosthetics. The work, led by Washington State University researchers and published in the ...
Medical Xpress / Gut bacteria may transform spinach, beets and plant iron into protective compounds
Researchers at Karolinska Institutet have discovered that gut bacteria can convert dietary nitrate and iron into protective molecules that may reduce the risk of cardiovascular and metabolic diseases. The study, published ...
Phys.org / Extreme rain shifts toward larger, less frequent storms across eastern US
Extreme precipitation events are among the most damaging natural disasters and a major concern in our changing climate. In the U.S., since 1980, the most destructive events alone have caused more than 2,800 deaths and $700 ...
Medical Xpress / Why immune responses to vaccines vary from person to person
Vaccines protect most people from serious illness, but the strength of that protection can vary considerably from one person to another. A new study led by Arizona State University helps us understand why.
Medical Xpress / Experimental pill targets nerve pain pathway, cutting opioid use after abdominal surgery
Opioids can be highly effective at relieving moderate to severe pain, whether it comes from surgery, an injury or conditions such as cancer. They work by activating opioid receptors in the brain and body, which block pain ...
Medical Xpress / Smart delivery systems could make noninvasive nasal routes to the brain possible
A protective layer that is extremely picky about not letting harmful substances in can sometimes also keep useful things from entering the very space it is meant to protect. The body's blood-brain barrier (BBB) is one such ...
Phys.org / AI agents coordinate behavior based on majority opinion—even when said opinions are meaningless
A new study published in Science Advances takes a closer look at how AI agents' choices are influenced by their peers. The team found that more advanced models tend to follow the majority when shown other agents' choices, ...
Medical Xpress / Medicare's paying less for cataract surgery: Eye doctors are turning to lucrative lasers
Cataract surgery—one of the most common operations paid for by Medicare—typically leaves enrollees owing a few hundred dollars. Some patients pay more to have their vision corrected during the procedure.
Medical Xpress / Simple mouth rinse may help detect stomach and colorectal cancer signals
It's widely understood that the microbiome—especially microbes found in the mouth and the gut—can have a profound effect on health. In a study published in the journal Cell Host & Microbe on Aug. 20, researchers report that ...
Phys.org / Designing supramolecular therapies to cross the blood-brain barrier
A new Northwestern Medicine study has uncovered key molecular design principles that could help supramolecular therapeutics cross the blood-brain barrier, a major challenge for this novel approach to treating neurological ...
Phys.org / 100-million-year-old molecular 'bypasses' may have helped grasses dominate landscapes and agriculture
100 million years ago, long before human intervention, ancestors of grasses, including wheat, rice and maize, developed "bypasses" in chemical pathways used to create two critical compounds: lignin and starch. These more ...
