Increase access to nature in all daily environments and in education, say environmental scientists
Although access to nature is a basic human right, people's actual use of green spaces is subject to inequalities. A Kobe University-led research team analyzed what conditions make it more likely that people are exposed to nature across generations: t.....»»
Nanopore technique shows transport mechanism of chaperone proteins at the single-molecule level
Proteins control most of the body's functions, and their malfunction can have severe consequences, such as neurodegenerative diseases or cancer. Therefore, cells have mechanisms in place to control protein quality......»»
Research team develops metallodrug-antibiotic combination strategy to combat superbugs
Antimicrobial resistance (AMR) bacterial infections have become a serious problem threatening human health worldwide. The overuse of antibiotics has promoted drug-resistant mutations in bacteria, causing almost all clinically used antibiotics to deve.....»»

Physical infrastructure on the moon will be critical to any long-term human presence there as both America and China gear up for a sustained human lunar presence. Increasingly, a self-deploying tower is one of the most essential parts of that physica.....»»
Human cases of H5N1 confirmed in California amid rapid dairy spread
The CDC confirmed two new bird flu cases, bringing the human tally to 17. Two California dairy farm workers who had contact with H5N1-infected cows have contracted an H5 avian inf.....»»
As bird flu rages through California cows, possible human case identified
If the case is confirmed by the CDC, it will be the 16th linked to the dairy outbreak. A California dairy farm worker who had contact with H5N1-infected cows appears to have contr.....»»
Study suggests statistical "noise" affects perceived evolutionary rates
For decades, researchers have observed that rates of evolution seem to accelerate over short time periods—say five million years versus fifty million years. This broad pattern has suggested that "younger" groups of organisms, in evolutionary terms,.....»»
