Scientists pin down the origins of the moon"s tenuous atmosphere
While the moon lacks any breathable air, it does host a barely-there atmosphere. Since the 1980s, astronomers have observed a very thin layer of atoms bouncing over the moon's surface. This delicate atmosphere—technically known as an "exosphere"—.....»»
Machine learning discovers "hidden-gem" materials for heat-free gas separation
Chemical separation, including gas separation, is a common process that is required for manufacturing and research. It accounts for a whopping 15% of U.S. energy consumption and produces millions of tons of carbon emissions......»»
First full 2-D spectral image of aurora borealis from a hyperspectral camera
Auroras are natural luminous phenomena caused by the interaction of electrons falling from the sky and the upper atmosphere. Most of the observed light consists of emission lines of neutral or ionized nitrogen and oxygen atoms and molecular emission.....»»
Japan sees hottest July since records began
Japan sweltered through its hottest July since records began 126 years ago, the weather agency said, as extreme heat waves fueled by climate change engulfed many parts of the globe......»»
A Band-Aid for the heart? New 3D printing method makes this, and much more, possible
In the quest to develop life-like materials to replace and repair human body parts, scientists face a formidable challenge: Real tissues are often both strong and stretchable and vary in shape and size......»»
Physicists report new insights into exotic particles key to magnetism
MIT physicists and colleagues report new insights into exotic particles key to a form of magnetism that has attracted growing interest because it originates from ultrathin materials only a few atomic layers thick. The work, which could impact future.....»»
