Phys.org / How light reflects on leaves may help researchers identify dying forests
Early detection of declining forest health is critical for the timely intervention and treatment of droughted and diseased flora, especially in areas prone to wildfires. Obtaining a reliable measure of whole-ecosystem health ...
Phys.org / Long school breaks tied to dip in cognitive test performance
Researchers at UConn and the University of Minnesota have discovered that there may be more to the "summer slide" phenomenon following a break in schooling than just forgetting material. In fact, the researchers found reliable ...
Phys.org / Ultrasonic sensor capable enables cuffless, non-invasive blood pressure measurement
A new technology has been developed that enables cuffless noninvasive blood pressure monitoring by using ultrasonic to track real-time changes in vascular diameter—without the need for a traditional cuff. The technology ...
Phys.org / Antibodies' decoy tactics for outmaneuvering pathogens could inspire next-generation treatments
Pathogens can create sticky situations. When microbes invade the body to cause an infection, often one of their first lines of attack is to cling tenaciously to the surfaces of targeted human cells.
Phys.org / Asteroid impact simulation reveals the hidden strength of space rocks
Physicists at the University of Oxford have contributed to a new study which has found that iron-rich asteroids can tolerate far more energy than previously thought without breaking apart—a breakthrough with direct implications ...
Phys.org / NASA cancels spacewalk due to medical issue and may bring the crew back early
NASA canceled its first spacewalk of the year and may bring its crew back early from the International Space Station due to an onboard medical issue.
Phys.org / Cosmic lens reveals hyperactive cradle of future galaxy cluster
Galaxy clusters are formed by a dense packing of many galaxies, making them the most massive structures in the universe. Their progenitors, protoclusters, show these galaxies in their infancy, offering a window to study how ...
Phys.org / Marine pollutants disrupt cellular energy production in seabirds
Common pollutants are disrupting energy production at the cellular level in wild seabirds, potentially affecting fitness, new research reveals. The study, published in Environment & Health, focused on Scopoli's shearwaters ...
Phys.org / Frequent Arctic wildfires could cut snow cover by 18 days, impacting global climate and ecology
The correlation between Arctic wildfires and abnormal snow cover under global warming is of growing concern. A comprehensive quantitative assessment by researchers at The Hong Kong Polytechnic University (PolyU) has shown ...
Phys.org / Portable biosensor could enable on-site PFAS detection
A portable biosensor developed at La Trobe University may allow rapid, on-site detection of toxic "forever chemicals" in water, removing the need for samples to be sent to specialist laboratories.
Phys.org / Understanding the link between nucleotide metabolism and chromatin assembly
A Northwestern Medicine study has revealed a previously unknown connection between two fundamental cellular processes, offering fresh insight into how human cells build and maintain chromatin, according to findings published ...
Phys.org / How population bottlenecks shape bacterial cooperation and competition
Microbes often display cooperative behavior in which individual cells put in work and sacrifice resources to collectively benefit the group. But sometimes, "cheater" cells in the group may reap the benefits of this cooperation ...
