(PhysOrg.com) -- Scientists have a good overall understanding of human vision: when light enters our eyes, it is focused by the lens and strikes the retina in the back of the eye. The light causes some of the millions of ...
(PhysOrg.com) -- By using light to change the elasticity of a DNA molecule, scientists have designed a molecular motor that can turn light into mechanical work. Unlike most previously reported molecular motors, the proposed ...
(Phys.org)—A group of researchers from the University of Groningen in the Netherlands have developed a way to change the handedness of a double-stranded metal helicate by photo and thermal stimulation by attaching bipyridine ...
The vibrational theory of olfaction explains several aspects of odorant detection that theories based purely on receptor binding do not. It provides for additional selectivity through receptors that are tuned to specific ...
A new catalytic chemical method for the synthesis of a large and important class of carbon-carbon double bonds has been developed by scientists from Boston College and MIT, the team reports in the journal Nature. The findings ...

In chemistry, isomers (from Greek ἰσομερής, isomerès; isos = "equal", méros = "part") are compounds with the same molecular formula but different structural formulas. Isomers do not necessarily share similar properties, unless they also have the same functional groups. There are many different classes of isomers, like stereoisomers, enantiomers, geometrical isomers, etc. (see chart below). There are two main forms of isomerism: structural isomerism and stereoisomerism (spatial isomerism).
