WASHINGTON, D.C. — U.S. Naval Research Laboratory (NRL) detailed an inverse relationship between the brightness of the solar corona and the velocity of coronal mass ejections (CMEs) in a scientific paper published in The Astrophysical Journal on July 3.
Can you imagine a life-saving molecule whose “twin” is a deadly poison? As surprising as it may seem, this chemical reality is known as “chirality”. Like a right hand and a left hand, two molecules can have the same composition, but a different shape and arrangement in space. And this difference can change everything. Understanding and controlling this phenomenon is crucial to drug design. A team from the University of Geneva (UNIGE), in collaboration with the University of Pisa, has developed a new family of remarkably stable chiral molecules. This work opens up new prospects for the design of geometry-controlled drugs. It is published in the Journal of the American Chemical Society.
Active radiant cooling is a promising strategy for outdoor thermal comfort, but there are practicality and safety concerns with the typically opaque and dark structures that are needed. A team of UCLA engineers and researchers has tested a new design that lowered the mean radiant temperatures 10 degrees during field studies. The scalable design, which combines water-cooled aluminum panels and see-through, infrared-reflective thin polymer film, brings an additional level of cooling beyond shade to help people who have to be outdoors on hot days while preserving a sense of safe and open space.
The interplay between quantum theory and gravity is one of the most challenging problems in physics today. Using new groundbreaking approach, researchers hope that quantum networks will help them test this interplay for the first time in actual experiments.
