Teaching life a new trick: Bacteria make boron-carbon bonds

In another feat of bioengineering, Caltech’s Frances Arnold, the Linus Pauling Professor of Chemical Engineering, Bioengineering and Biochemistry, and her team have created bacteria that can, for the first time, make chemical compounds containing bonds between boron and carbon. Before now, such boron-carbon bonds came only from the laboratories of chemists and could not be produced by any known life form.

A quantum leap in nanoparticle efficiency

In an international study Univ. of Melbourne and NIST found that pairs of closely spaced nanoparticles made of gold can act as “optical antennas”. These antennae concentrate the light shining on them into tiny regions located in the gap between the nanoparticles. Researchers found the precise geometry of nanoparticle pairs that maximizes light concentration, resolving a hotly debated area of quantum physics.
