Medical Xpress / Supposedly harmless peptide may be linked to Alzheimer's disease
While companies developing drugs to treat Alzheimer's disease have spent decades and many billions of dollars targeting amyloid beta due to its role in clogging patients' brains with harmful deposits, a biochemist at the ...
Medical Xpress / Time changes still frustrate Americans, and the fall shift appears to linger longer
Individuals have a more negative reaction to the societal time change to Standard Time (ST) in the fall than to Daylight Saving Time (DST) in the spring, according to a study published in the open-access journal PLOS One. ...
Phys.org / Permafrost is key to carbon storage. That makes northern wildfires even more dangerous
The devastating wildfires in northern Canada in recent years have climate consequences that go far beyond smoke and carbon dioxide released into the atmosphere, according to a new study co-authored by two NAU researchers. ...
Phys.org / Catching light in air: Programmable Mie voids boost light matter interaction
Atomically thin semiconductors such as tungsten disulfide (WS2) are promising materials for future photonic technologies. Despite being only a single layer of atoms thick, they host tightly bound excitons—pairs of electrons ...
Phys.org / NASA finds source of Artemis II problem that forced rollback from the launch pad
NASA announced it had found the source of a helium flow blockage that forced it to roll the Artemis II rocket back from the launch pad at Kennedy Space Center and delay its lunar fly-by mission until at least April.
Tech Xplore / Improved EV battery gains will outmatch degradation from climate change, research shows
Climate change was poised to create an interesting catch-22 for electric vehicles. Electrifying transportation can go a long way to reducing carbon emissions that are driving up global temperatures. But warmer temperatures ...
Medical Xpress / Greater quality of life, higher satisfaction seen with robotic-assisted total knee arthroplasty
Robotic-assisted total knee arthroplasty (raTKA) is associated with higher satisfaction and greater improvement in quality of life (QOL) than conventional TKA (cTKA), according to a study presented at the annual meeting of ...
Medical Xpress / AI cancer tools may rely on 'shortcut learning' rather than genuine biological signals
Artificial intelligence tools are increasingly being developed to predict cancer biology directly from microscope images, promising faster diagnoses and cheaper testing. But new research from the University of Warwick, published ...
Phys.org / Modern twist on wildfire management methods has a bonus feature that protects water supplies
Wildfires are among the most economically costly natural disasters and are becoming more severe and frequent due to global warming. The United Nations Office for Disaster Risk Reduction estimates that global damage from wildfires ...
Phys.org / Drinking water at risk long after wildfires, study warns
Canada's drinking water can remain at risk long after wildfires burn out, according to a UBC-led global review that found water-quality impacts often emerge months or years later—not just immediately after a fire. Researchers ...
Phys.org / The 'Bloom cycle' is a newly described biochemical pathway that explains key plant processes
For decades, the basics of plant growth have been taught in grade school: Plants make their food out of water from the soil, light from the sun and carbon dioxide from the air in a process called photosynthesis. What gets ...
Phys.org / Hard-to-make diastereomers: How a cage-like allyl reagent changes the outcome
Diastereomers are structurally identical molecules that are not mirror images of each other. Diastereomers can have different biological activities, potencies or toxicities, which means they can influence biological systems, ...
