Phys.org / Honeybees struggle to gather nectar in August, direct measurements reveal
Letting late-summer weeds grow could help honeybees when they find it most challenging to gather nectar, according to new research published in the journal, Functional Ecology.
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 ...
Medical Xpress / Common arthritis pill repurposed to boost hair regrowth in alopecia patients
Upadacitinib is a medication widely used for the treatment of rheumatoid arthritis that works by inhibiting Janus kinase (JAK) enzymes, which are involved in signaling pathways that regulate immune responses. Now, scientists ...
Tech Xplore / At 0.8 nanometers, carbon film may replace two layers in future chip wiring
As transistors inside microchips continue to shrink, the metal wiring that connects them is becoming a growing obstacle to faster, more energy-efficient chips. Narrower wires have greater electrical resistance, while smaller ...
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 / 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 ...
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 ...
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 / 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 / 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 / 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 / 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 ...
