Collisions with electrons cool molecular ions
A lone molecule free in cold space will cool by slowing down its rotation—it will spontaneously lose its rotational energy in quantum transitions, typically only once in many seconds. This process can be accelerated, slowed down, or even inverted b.....»»

A new type of metallacrown ether based on polyoxometalate opens research opportunities
Crown ethers were discovered in 1967. They were then modified by adding a metal-containing unit, creating metallacrown ethers. These metallacrown ethers have been the subject of intensive research. Depending on the molecular makeup of the metallacrow.....»»
Research explores the cooling effects of "scuba-diving" in lizards
Anoles are the scuba-diving champions of the lizard world, able to stay underwater for more than 16 minutes. For animals whose body temperature depends on the environment, time spent in a cool running stream can have some tradeoffs......»»
Conduction-cooled accelerating cavity proves feasible for commercial applications
From televisions to X-ray machines, many modern technologies are enabled by electrons that have been juiced up by a particle accelerator. Now, the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility has worked with General Atom.....»»
Novel RNA- or DNA-based substances can protect plants from viruses, scientists show
Individually tailored RNA or DNA-based molecules are able to reliably fight off viral infections in plants, according to a new study by the Martin Luther University Halle-Wittenberg (MLU) published in the International Journal of Molecular Sciences......»»
Research team reveals cellular and molecular basis of spur development in Impatiens uliginosa
As an important reproductive organ of angiosperms, flowers have a clear purpose and adaptive significance in their various characteristics. As a typical floral evolutionary feature, the floral spur is a tubular structure extending from the petal, whi.....»»
Molecular mechanism of transmembrane bilirubin transport by human ABCC2 transporter revealed
The metabolic process of bilirubin has been a focus of medical research since the abnormal accumulation of bilirubin has been found to be associated with a variety of diseases. Bilirubin is a substance produced by the breakdown of aging or damaged re.....»»

Scientists discover why ripe fruit is more susceptible to necrotrophic pathogens than unripe fruit
In a recent study published in Molecular Plant, researchers have elucidated the mechanism underlying the increased susceptibility to necrotrophs during fruit ripening and have developed a rapid strategy to improve tomato fruit resistance to necrotrop.....»»
How molecular "handedness" emerged in early biology
Molecules often have a structural asymmetry called chirality, which means they can appear in alternative, mirror-image versions akin to the left and right versions of human hands. One of the great mysteries about the origins of life on Earth is that.....»»
Light stimulates a new twist for synthetic chemistry
Molecules that are induced by light to rotate bulky groups around central bonds could be developed into photo-activated bioactive systems, molecular switches, and more......»»
