Molecules move faster on a rough terrain

Roughness, the presence of irregularities on a surface, is commonly associated with slower motion and stickiness. This is true at different length scales: at human size (1 meter), it takes longer to walk along a path that ...

'Russian doll' molecules could really clean up

The Nitschke Group at the University of Cambridge designs hollow molecules that act as capsules or cages that enclose guest molecules. These cages have exciting potential applications in a variety of fields. They could, for ...

Hook-on drugs: New delivery strategy for K-Ras disruption

"The strategy was to design the drug to be able to hook into the hole of the FTase and GGTase I, otherwise the surface of the proteins are too large and slippery," Dr. Junko Ohkanda of Shinshu University explains her strategy ...

Decoding messages in the body's microscopic metropolises

A study aimed at identifying and examining the small messenger proteins used by microbes living on and inside humans has revealed an astounding diversity of more than 4,000 families of molecules – many of which have never ...

Using lasers to study explosions

An explosion is a complex event involving quickly changing temperatures, pressures and chemical concentrations. In a paper in the Journal of Applied Physics a special type of infrared laser, known as a swept-wavelength external ...
