Phys.org / Rich cities, broke neighbors: Study exposes metro-level wealth divide
Local governments in the United States are responsible for many of the services people rely on daily—schools, parks, public safety, and more. But the resources available to fund these services depend heavily on the amount ...
Medical Xpress / Beauty may be 'easy on the eyes' because it saves brain power
Humans may find images that take less energy to process aesthetically pleasing, suggesting that our attraction to beauty is at least partially an energy conservation strategy.
Phys.org / Ant brood signal deadly infection in altruistic self-sacrifice
Ant colonies operate as tightly coordinated "superorganisms" with individual ants working together, much like the cells of a body, to ensure their collective health. Researchers at the Institute of Science and Technology ...
Phys.org / Political alignment, not just supply options, drives US-China decoupling
Efforts to "decouple" U.S. supply chains from China are only taking hold in industries where American firms can shift production to allied or politically aligned countries, according to new research by scholars at the University ...
Medical Xpress / Cell nucleus shape may influence cancer treatment success
Cancer cells with a cell nucleus that is easily deformed are more sensitive to drugs that damage DNA. These are the findings of a new study by researchers at Linköping University in Sweden. The results may also explain why ...
Medical Xpress / Just 20 minutes of exercise twice a week may help slow dementia, study finds
How much physical activity—and how often—is needed to help stall dementia? For older adults with mild cognitive decline, there is now an answer: at least 20 minutes, at least twice weekly.
Phys.org / Scientists can finally answer an old question about cellular aging
After a finite number of divisions, cells simply give up. As each round of replication trims their telomeres—the protective caps at the chromosome ends—those caps eventually become too short to prevent chromosome ends ...
Phys.org / NASA tests drones in Death Valley, preps for Martian sands and skies
When NASA engineers want to test a concept for exploring the Red Planet, they have to find ways to create Mars-like conditions here on Earth. Then they test, tinker, and repeat.
Phys.org / Zero waste in schools? Why factoring in labor is essential
Over the last decade, I've worked closely with Montréal educators and students to better understand how climate change education occurs in schools—and how climate change curricula and policies shape everyday experiences ...
Medical Xpress / Light-activated protein triggers cancer cell death by raising alkalinity
One of the hallmarks of cancer cells is their ability to evade apoptosis, or programmed cell death, through changes in protein expression. Inducing apoptosis in cancer cells has become a major focus of novel cancer therapies, ...
Phys.org / Evidence of rain-driven climate on Mars found in bleached rocks scattered in Jezero crater
Rocks that stood out as light-colored dots on the reddish-orange surface of Mars now are the latest evidence that areas of the small planet may have once supported wet oases with humid climates and heavy rainfall comparable ...
Phys.org / Fossils reveal anacondas have been giants for over 12 million years
A University of Cambridge-led team has analyzed giant anaconda fossils from South America to deduce that these tropical snakes reached their maximum size 12.4 million years ago and have remained giants ever since.
