FOR THE FIRST TIME, researchers have discovered a molecule in interstellar space that exhibits chirality: It can exist in two forrris that are composed of the same atoms, but are mirror images of each other. Think of chiral molecules as being like a pair of gloves. Each glove has five ...
Crystal parameters and refinement statistics are summarized in Table 1. In the asymmetric unit of the tetragonal space group, one complex of one protein molecule bound to one L-oligonucleotide molecule is present. An analysis of all contacts including symmetry-related molecules using the programmes ...
In a first-of-its-kind achievement, scientists at the University of Iowa, the University of Illinois at Urbana-Champaign and Princeton University have directly imaged the magnetic interactions between two magnetic atoms less than one nanometer apart and embedded in a semiconductor chip. ...
The final instrument, the Visible Tunable Filter, will capture very high-resolution images of the sun while performing high speed scans of the light that can identify atoms and molecules. Inouye is meant to operate for 44 years, which should cover two of the sun's full 22-year solar cycles...
On the one hand, the study of an electron pair is useful for physicists who want to gain a better understanding of how atoms and molecules interact with light as this interaction usually involves two or more electrons. It is useful for chemistry, on the other hand, if they are able to ...
"The way we can tell this object is very distant is by measuring its redshift, which is a measure of the universe's expansion speed. More distant objects have a larger redshift. To measure redshift, you use a spectral line of atoms or molecules, each of which has a recognizable, discr...
The auroral ovals around the Earth's magnetic poles are produced by the collisions between energetic particles precipitating from solar wind and atoms or molecules in the upper atmosphere. The morphology of auroral oval acts as an important mirror reflecting the solar wind-magnetosphere-ionosphere coupl...

Amino acids, the building blocks of proteins, are chiral molecules. Living organisms primarily make proteins fromamino acids with L configurations. The D configuration, however, has many other functions in nature.Bacteria, for example, use D configurationamino acidsto make their cell walls.Mammalsuse...
I. Electronic properties of the water molecule in a Monte Carlo sample of liquid water molecules studied with standard basis sets The reaction field (RF) potential, which in the exact theory is given as a compact functional form factorized into a solute charge density and a RF susceptibility, ...
