Phys.org / Cells pulse together as they grow—and malignant cells pulse the longest
Epithelial cells are the tiny shields that line and protect our bodies. In a developing embryo, epithelial cells grow, divide and move into positions to form the outer layers of our skin and the surfaces of our organs and ...
Phys.org / Wildfires have destroyed an area of protected tropical forest twice the size of Wales since 2001, study reveals
Over 4 million hectares (9.9 million acres) of protected tropical forest—an area double the size of Wales—have been lost to wildfires since 2001.
Phys.org / Long-lost convent rediscovered under a soccer field in Denmark
A medieval monastery complex, long believed to be lost, has now been identified using ground-penetrating radar (GPR) in Roskilde, Denmark. The investigations have uncovered extensive and well-preserved remains of the St Clare's ...
Phys.org / A new way to beat jet lag? Engineered cells speed circadian adjustment
Adjusting to a new time zone or work schedule can leave the body's internal clock out of sync for days, contributing to sleep disruption, metabolic changes and other health consequences. Researchers at Rice University and ...
Phys.org / Tiny DNA rotor lets microscopes track gene transcription one base pair at a time
Scientists often describe life as a series of chemical reactions. Pallav Kosuri, Ph.D., describes life as movement. Chemical reactions are how you drive the movement of atoms, proteins, cells and bodies—without movement, ...
Phys.org / EU cities plan to compensate for a fifth of their emissions through carbon removal, but few have thought through how
An analysis of 103 European cities' climate-neutral plans for 2030 (including 22 capital cities) shows that municipalities are planning to rely on carbon removal to compensate for about a fifth of their emissions. This would ...
Phys.org / Butterfly-inspired technology could change the way we monitor air
Respiratory infectious diseases and air pollution remain persistent global health challenges. Yet the tools used to monitor airborne threats are often expensive, power-hungry and difficult to deploy outside laboratories.
Phys.org / New AI model detects hidden signs of solar eruptions hours before they emerge
Long before dark sunspots appear on the sun's surface, a new active region—where powerful solar eruptions can originate—begins showing subtle signs of its formation. Now, researchers say a new artificial intelligence model ...
Phys.org / Scientists develop method to deliver sugars directly into cells
Sugars, or glycans, play a crucial role in biology—from cell signaling and recognition to interactions with pathogens. Changes in glycosylation are also associated with diseases including cancer. But studying glycans poses ...
Phys.org / Doomscrolling at work wastes time, but the real cost is what happens after
Whether on lunch break or on the clock, many employees scroll through the news and social media during the workday. Researchers found that employees who "doomscroll" at work suffer hidden costs that extend beyond lost productivity.
Phys.org / Arctic balloon samples trace marine sugars from the ocean to cloud-forming heights
Salt and sugar from the sea can rise as far as the free troposphere, thereby influencing both cloud formation and the Arctic climate. This is the finding of balloon measurements carried out by a team of researchers on Spitsbergen ...
Phys.org / Why climate-driven droughts and floods rarely become international news
Three factors—spectacular images, a high death toll and strong personal ties—make it more likely that the media in one country will report on a natural disaster in another, according to a study by the University of Bonn, ...
