Controlling the formation of graphene nano-scrolls
Can graphene - a newly discovered form of pure carbon that may one day replace the silicon in computers, televisions, mobile phones and other common electronic devices - be made to bend, twist and roll? Physicists at UC San Diego and Boston University think so.

Read moreA little less force: Making Atomic Force Microscopy work for cells
Researchers have developed nano-sized cantilevers whose gentle touch could help discern the workings of living cells and other soft materials in their natural, liquid environment. Used in combination with a revolutionary detection mechanism, this new imaging tool is sensitive enough to investigate soft materials without the limitations present in other cantilevers. By placing a nanowire cantilever in the focus of a laser beam and detecting the resulting light pattern, scientists at the Molecular Foundry believe atomic force microscopy can be used to non-destructively image the surface of a biological cell.

Read moreMolecular 'machine' is a tail-biter which functions as a nanoswitch
The ouroboros (ancient Greek for 'tail devourer') is a motif found in many cultures: a snake biting its own tail, it symbolizes eternity and cycles. Researchers have now constructed a molecular tail devourer, and have named this new class of compound 'ouroborand'. Their tail-biter is a molecular 'machine', which functions as a nanocontainer with a built-in switch that regulates access to the cavity.
