Chip-based optical tweezers levitate nanoparticles in a vacuum

Researchers have created tiny chip-based optical tweezers that can be used to optically levitate nanoparticles in a vacuum. Optical tweezers—which employ a tightly focused laser beam to hold living cells, nanoparticles ...

Antlions use sand-throwing to help capture prey

A team of researchers from Kiel and Aarhus universities has found that there is more to the sand-throwing done by antlions than previously thought. In their paper published in Journal of the Royal Society Interface, the group ...
