Medical Xpress / For young adults, limiting social media use doesn't improve well-being
What happens when young adults are asked to slash their social media use to 30 minutes a day? In a new set of studies, most did not follow through, and those who did cut back reported no greater improvement in well-being ...
Phys.org / A new kind of polymer with two faces and a twist control electron spin
Researchers from the University of Osaka have developed a new class of chiral semiconducting polymers that can generate highly spin-polarized electrical currents. The team's unique molecular design allows the polymers to ...
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.
Medical Xpress / Disease tolerance research points to treatments that limit infection damage instead of killing microbes
Two identical mice experience the same deadly infection. One survives, while the other dies. Why? Scientists long thought the answer lay in the pathogen burden—the amount of harmful bacteria present in the body. They assumed ...
Phys.org / How well do past extinctions predict extinction risk today?
In the last few centuries, mammals and other animals have been going extinct at least 100 times faster than they did before humans arrived on the scene. So who will be next? Which species are most likely to survive, and which ...
Medical Xpress / Living near dry cleaners linked to increased likelihood of Parkinson's disease
People living near dry cleaners may have a higher risk of developing Parkinson's disease, according to a new nationwide study led by researchers at Barrow Neurological Institute in Phoenix.
Phys.org / Tobacco companies helped flood the federal comment process that stalled menthol cigarette ban
When the U.S. Food and Drug Administration (FDA) proposed banning menthol cigarettes and flavored cigars in 2022, nearly 250,000 public comments flooded in—a record response that led the Biden administration to delay a final ...
Phys.org / Oxygen vacancies unlock fast lithium-ion transport in battery material
Lithium titanate (LTO, Li4Ti5O12) is a well-established battery material that in its pristine state is a poor conductor of lithium ions. It develops high ionic conductivity only during charging, when additional lithium ions ...
Phys.org / Spinach peptide discovery leads to citrus greening treatment
A citrus greening disease treatment rooted in more than a decade of research at Texas A&M AgriLife Research has reached a milestone on the path to commercial availability. The U.S. Environmental Protection Agency has granted ...
Phys.org / Illuminating the limits of the international unit of light, the candela
The candela, the international unit of light in use for almost a century, forms the basis of photometry. According to a new study, measurements derived from it systematically misjudge the brightness of colored light sources ...
Phys.org / What comes after fire? What forests need to survive in a warming world
Jennifer Bhatnagar spent the summer of 2023 traversing barren hillsides blackened by wildfire in northern California. She walked through devastated properties, examined the hot soil beneath her feet, collected samples and ...
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 ...
