Superselective colloid-surface binding visualized

Rather than one key and one strong lock, biology often uses tens or hundreds of weaker links to bind parts together, such as cell membranes. This allows for selectivity and also reversibility—the binding can also be undone. ...

Visualizing microscopic 3D displacements over large areas

A team of researchers from PSL University, Harvard University and China University of Petroleum, has developed a way to visualize microscopic 3D displacements of moving objects or events over large areas. In their paper published ...

New tractor beam has potential to tame lightning

Lightning never strikes twice, so the saying goes, but new technology may allow us to control where it hits the ground, reducing the risk of catastrophic bushfires.

Single laser produces high-power dual comb femtosecond pulses

Researchers have developed a new approach that uses a single laser cavity to create two high-power optical frequency combs emitting high-power femtosecond pulses. The new development paves the way for portable dual-comb light ...

How to take a picture of a light pulse

Until now, complex experimental equipment was required to measure the shape of a light pulse. A team from TU Wien (Vienna), MPI Garching and LMU Munich has now made this much easier.
