Mapping hidden meltwater paths in glaciers
Norwegian and Estonian researchers have developed a method to map hidden meltwater paths in glaciers. Having a better understanding of how water moves inside and under the glaciers helps to better predict the motion, melting rates, and possible sudde.....»»
Researchers propose strategy to design high-entropy environmental barrier coating material
In aviation technology, environmental barrier coatings (EBCs) are designed to protect the turbine components made of SiCf/SiC ceramic matrix composites (CMCs) from environmental degradations in the combustion environment. Multicomponent/high-entropy.....»»
Melting Antarctic could impact oceans "for centuries"
Rapidly melting Antarctic ice threatens to dramatically slow deep-water currents in the world's oceans, scientists say, impacting the spread of fresh water, oxygen and life-sustaining nutrients for centuries......»»

In two new studies, researchers at the National Institute of Standards and Technology (NIST) have greatly improved the efficiency and power output of a series of chip-scale devices that generate laser light at different colors while all using the sam.....»»
Third pole darkening affects local and remote climates, finds study
Owing to global warming effects, the Tibetan Plateau (TP) region has experienced drastic changes in its land surface, characterized by melting glaciers, loss of snow cover, and vegetation greening. These, in turn, have led to a darkening of the land.....»»
The Greenland Ice Sheet is close to a melting point of no return, says new study
The Greenland Ice Sheet covers 1.7 million square kilometers (660,200 square miles) in the Arctic. If it melts entirely, global sea level would rise about 7 meters (23 feet), but scientists aren't sure how quickly the ice sheet could melt. Modeling t.....»»
