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.

Reducing School Bus Pollution Improves Children's Health
ANN ARBOR--Use of clean fuels and updated pollution control measures in the school buses 25 million children ride every day could result in 14 million fewer absences from school a year, based on a study by the University of Michigan and the University of Washington. In research believed to be the first to measure the individual impact on children of the federal mandate to reduce diesel emissions, researchers found improved health and less absenteeism, especially among asthmatic children.

U-M Researchers Find Protein That May Signal More Aggressive Prostate Cancers
ANN ARBOR--University of Michigan researchers have discovered a biomarker that may be a potentially important breakthrough in diagnosing and treating prostate cancer. Biomarkers in the body are analogous to the warning lights in cars that signal something might need repairing. In our bodies, they indicate if something's wrong or if we're about to get sick or if we're predisposed to certain illnesses.
