13-01-30 Researchers employing a century-old observational technique have determined the precise configuration of humulones, substances derived from hops（啤酒花） that give beer its distinctive flavor. That might not sound like a big deal to the average bre...

13-01-18 Gas separation is crucial for many industrial processes including obtaining nitrogen or oxygen from air and purifying natural gas or hydrogen. Currently, the most energy efficient method for separating gases involves polymer membranes, however, most...

12-10-30 Scientific research has provided us with a fundamental understanding of how light (via photons) and electricity (via electrons) move within and between materials at the micrometer or nanometer levels, making possible a wide variety of miniature devi...

12-03-20 A new method to reveal the structure of proteins could help researchers understand biological molecules -- both those involved in causing disease and those performing critical functions in healthy cells. For roughly a decade, a technique called soli...

11-03-08 All our daily activities, from driving to work to solving a crossword puzzle, depend on signals carried along the body's vast network of neurons. Propagation（传播，繁殖） of these signals is, in turn, dependent on myriad（无数的） small molecules w...

11-01-20 Ebola, a virus that causes deadly hemorrhagic fever（出血热） in humans, has no known cure or vaccine. But a new study by University of Illinois at Chicago scientists has uncovered a family of small molecules which appear to bind to the virus's oute...

11-01-09 In the Old West, camps sent smoke signals across distances to share key developments or strategy. Likewise, two important signaling molecules communicate across nerve cells to regulate electrical and chemical activity, neuroscientists from the UT He...

10-06-11 Cornell University researchers recently stretched（伸直，舒展） individual molecules and watched electrons flow through them, proving that single-molecule devices can be used as powerful new tools for nanoscale science experiments. The finding, repo...

10-05-11 An Arizona State University graduate student, Jinglin Fu, in collaboration with Biodesign Institute researchers Neal Woodbury and Stephen Albert Johnston, has pioneered a technique that improves on scientists' ability to harness and modulate（调节，...

10-04-05 A team of scientists led by the University of East Anglia (UEA) has discovered a brand new group of molecules（分子，微粒） which could help fight the spread of cancer and other diseases. The new molecules are synthetic（合成的，人造的） derivatives...
