Research provides insight into novel approach which could be used in pharmaceutical drug synthesis New research shows how metal surfaces that lack mirror symmetry could provide a novel approach towards manufacturing pharmaceuticals. These 'intrinsically chiral' metal surfaces offer potential new ways to control chiral chemistry, pointing to the intriguing possibility of using heterogeneous catalysis in drug synthesis. Such surfaces could also become the basis of new biosensor...

Scientists are reporting discovery of what may be the "ancestral Eve" crystal that billions of years ago gave life on Earth its curious and exclusive preference for so-called left-handed amino acids. Those building blocks of proteins come in two forms "” left- and right-handed "” that mirror each other like a pair of hands. Their study, which may help resolve one of the most perplexing mysteries about the origin of life, is in ACS' Crystal Growth & Design, a bi-monthly...

NEW YORK, March 18 /PRNewswire/ -- Within the general question of the chemical origin of life lies the question of handedness, or chirality (a term derived from the Greek word for hand). Critically important molecules that make up life -- including DNA, RNA, polysaccharides and proteins -- are chiral. This means there are mirror image forms that are not identical, much as one's left and right hands are different and are mirror reflections. (Logo:...

Flash back three or four billion years "” Earth is a hot, dry and lifeless place. All is still. Without warning, a meteor slams into the desert plains at over ten thousand miles per hour. With it, this violent collision may have planted the chemical seeds of life on Earth.Scientists presented evidence today that desert heat, a little water, and meteorite impacts may have been enough to cook up one of the first prerequisites for life: The dominance of "left-handed" amino acids, the...

BERKELEY -- The dry, dusty, treeless expanse of Chile's Atacama Desert is the most lifeless spot on the face of the Earth, and that's why Alison Skelley and Richard Mathies joined a team of NASA scientists there earlier this month. The University of California, Berkeley, scientists knew that if the Mars Organic Analyzer (MOA) they'd built could detect life in that crusty, arid land, then it would have a good chance some day of detecting life on the planet Mars. In a place that hadn't...
