Meteorite Source for Life's Handedness Scientists have long speculated that life's preference for left-handed amino acids may have been triggered by compounds brought to Earth by meteorites. Now they've shown exactly how two crucial steps in this process could happen. mark for My Articles similar articles

Switching chirality in amino acids An international team of scientists has developed a purely chemical approach to interconvert L- and D-amino acids. This method could rival enzymatic routes used in industry, and enable cheaper production of some pharmaceuticals. mark for My Articles similar articles

Microwaves show their hand The chirality of a gas phase molecule held in an electric field can be revealed using microwave spectroscopy.
