Super-fine Sound Beam Could One Day Be an Invisible Scalpel

Published: December 20, 2012.
Released by University of Michigan  

ANN ARBOR—A carbon-nanotube-coated lens that converts light to sound can focus high-pressure sound waves to finer points than ever before. The University of Michigan engineering researchers who developed the new therapeutic ultrasound approach say it could lead to an invisible knife for noninvasive surgery.

Sharing That Crowded Holiday Flight with Countless Hitchhiking Dust Mites
ANN ARBOR--As if holiday travel isn't stressful enough. Now University of Michigan researchers say we're likely sharing that already overcrowded airline cabin with countless tiny creatures including house dust mites. "What people might not realize when they board a plane is that they can share the flight with a myriad of microscopic passengers-- including house dust mites--that take advantage of humanity's technological progress for their own benefit," said U-M biologist Pavel Klimov.
