Creation of coherent states in molecules by incoherent electrons

Coherent states of negative ion resonances in electron-molecule interaction are observed in experiments on e -- H2 and e -- D2 reactions. A forward-backward asymmetry is observed in the ejection of H- ions from H2 in this reaction, whereas the asymmetry in D- from D2 is weaker, but changes direction with electron energy. These results arise from attachment of a single electron to a molecule forming coherent superposition of odd and even parity states of negative ions.

The microbial anatomy of an organ

The first 3-D spatial visualization tool has been developed for mapping 'omics' data onto whole organs. The tool helps researchers and clinicians understand the effects of chemicals, such as microbial metabolites and medications, on a diseased organ in the context of microbes that also inhabit the region. The work could advance targeted drug delivery for cystic fibrosis and other conditions where medications are unable to penetrate.
