Physicists shine new light on ultra-fast atomic processes      (via sciencedaily.com)     Original source 

Scientists report incredibly small time delays in a molecule's electron activity when the particles are exposed to X-rays. To measure these tiny high-speed events, known as attoseconds, researchers used a laser to generate intense X-ray flashes that allowed them to map the inner workings of an atom.

Chalk-based coating creates a cooling fabric      (via sciencedaily.com)     Original source 

In the scorching heat of summer, anyone who spends time outside could benefit from a cooling fabric. While there are some textiles that reflect the sun's rays or wick heat away, current options require boutique fibers or complex manufacturing processes. But now, demonstrations of a durable chalk-based coating show it can cool the air underneath treated fabric by up to 8 degrees Fahrenheit.

Quality control: Neatly arranging crystal growth to make fine thin films      (via sciencedaily.com)     Original source 

Researchers have succeeded in forming metal-organic framework thin films on a substrate while controlling the growth direction of crystals so that they are arranged neatly without gaps. The resulting thin films of unprecedented high quality can be expected for use as optical sensors, optical elements, and transparent gas adsorption sheets.

Explanation found for X-ray radiation from black holes      (via sciencedaily.com)     Original source 

Researchers have succeeded in something that has been pursued since the 1970s: explaining the X-ray radiation from the black hole surroundings. The radiation originates from the combined effect of the chaotic movements of magnetic fields and turbulent plasma gas.

Expanding a child's heart implant with light      (via sciencedaily.com)     Original source 

Children born with certain heart defects undergo a series of invasive surgeries early in life. The first surgery includes implantation of a shunt to improve blood flow. However, as children grow, the shunt must be replaced to accommodate their changing bodies. Now, researchers report designing a shunt that expands when activated by light. This device could reduce the number of open-chest surgeries these children receive.

Forest loss intensifies climate change by increasing temperatures and cloud level, which leads to decrease of water      (via sciencedaily.com)     Original source 

Researchers report that deforestation during the last two decades induced a higher warming and cloud level rise than that caused by climate change, which threatens biodiversity and water supply in African montane forests.

It's a rave: Underground acoustics amplify soil health      (via sciencedaily.com)     Original source 

Barely audible to human ears, healthy soils produce a cacophony of sounds in many forms -- a bit like an underground rave concert of bubble pops and clicks. Special recordings made by ecologists show this chaotic mixture of soundscapes can be a measure of the diversity of tiny living animals in the soil, which create sounds as they move and interact with their environment.

New microscope offers faster, high-resolution brain imaging      (via sciencedaily.com)     Original source 

Researchers have developed a new two-photon fluorescence microscope that captures high-speed images of neural activity at cellular resolution. By imaging much faster and with less harm to brain tissue than traditional two-photon microscopy, the new approach could provide a clearer view of how neurons communicate in real time, leading to new insights into brain function and neurological diseases.

Nearly 25% of European landscape could be rewilded, researchers say      (via sciencedaily.com)     Original source 

Europe's abandoned farmlands could find new life through rewilding, a movement to restore ravaged landscapes to their wilderness before human intervention. A quarter of the European continent, 117 million hectares, is primed with rewilding opportunities, researchers report.
