Using corkscrew lasers to separate mirror molecules

Innovative approach could deepen insight into the mysterious handedness of life

13-Dec-2019

Many of the molecular building blocks of life have two versions that are mirror images of one another, known as enantiomers. Although seemingly identical, the two enantiomers can have completely different chemical behaviour – a fact that has major implications in our day-to-day lives. For ...

Self-driving microrobots

12-Dec-2019

Most synthetic materials, including those in battery electrodes, polymer membranes, and catalysts, degrade over time because they don't have internal repair mechanisms. If you could distribute autonomous microrobots within these materials, then you could use the microrobots to continuously make ...
