When Hongrui Jiang looked into a fly's eye, he saw a way to make a tiny lens so "smart" that it can adapt its focal length from minus infinity to plus infinity-without external control. Incorporating hydrogels that respond to physical, chemical or biological stimuli and actuate lens function, these liquid microlenses could advance lab-on-a-chip technologies, optical imaging, medical diagnostics and bio-optical microfluidic systems.

Nanotechnology Enables Low-Dose Treatment of Atherosclerotic Plaques

In laboratory tests, one very low dose of a drug was enough to show an effect on notoriously tenacious artery-clogging plaques. What kind of drug is that potent? It's not so much the drug itself as how it was delivered.
