New approach could accelerate efforts to catalogue vast numbers of cells

Artistic sketches can be used to capture details of a scene in a simpler image. Researchers are now bringing that concept to computational biology, with a novel method that extracts comprehensive samples — called ‘sketches’ — of massive cell datasets that are easier to analyze for biological and medical studies.

What the wheat genome tells us about wars

First they mapped the genome of wheat; now they have reconstructed its breeding history. Scientists have examined the genetic diversity of wheat varieties in the WHEALBI study. By doing so, they discovered which cereals our ancestors cultivated, where today’s wheat comes from, and what the Cold War has to do with it all.

Stickier than expected: Hydrogen binds to graphene in 10 femtoseconds

Graphene is an extraordinary material consisting of pure carbon just a single atomic layer thick. It is extremely stable, strong and conductive. In electronics, however, graphene has crucial disadvantages. It cannot be used as a semiconductor, since it has no bandgap. Now researchers have produced an ”atomic scale movie” showing how hydrogen atoms can chemically bind to graphene to produce a bandgap in one of the fastest reactions ever studied.
