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.

More Secondary Schools Serve Healthier Lunches
ANN ARBOR--Secondary students found healthier foods on more lunch menus in 2013 than in 2011, resulting in fewer nutrition disparities for small schools or those with racially diverse student bodies. The findings by University of Michigan researchers show significant improvements made in the National School Lunch Program at public middle and high schools in 2013 after many years of meal disparities based on school size or demographics.
Teens with Medical Marijuana Cards Much Likelier to Say They're Addicted
ANN ARBOR--A new University of Michigan study finds that teens using marijuana for medical reasons are 10 times more likely to say they are hooked on marijuana than youth who get marijuana illegally. The study is the first to report on a nationally representative sample of 4,394 high school seniors and their legal or illegal medical marijuana use as it relates to other drug use. In the study, 48 teens had medical marijuana cards, but 266 teens used medical marijuana without a card.
Lung Simulation Could Improve Respiratory Treatment
ANN ARBOR - The first computer model that predicts the flow of liquid medication in human lungs is providing new insight into the treatment of acute respiratory distress syndrome. University of Michigan researchers are using the new technology to uncover why a treatment that saves the lives of premature babies has been largely unsuccessful in adults.
U-M, Partners Predict Severe Harmful Algal Bloom for Lake Erie
ANN ARBOR--University of Michigan researchers and their colleagues predict that the 2015 western Lake Erie harmful algal bloom season will be among the most severe in recent years and could become the second-most severe behind the record-setting 2011 bloom.
Discovery of Nanotubes Offers New Clues About Cell-to-cell Communication
ANN ARBOR--When it comes to communicating with each other, some cells may be more "old school" than was previously thought. Certain types of stem cells use microscopic, threadlike nanotubes to communicate with neighboring cells, like a landline phone connection, rather than sending a broadcast signal, researchers at University of Michigan Life Sciences Institute and University of Texas Southwestern Medical Center have discovered.
Sleeping on the Job? Actually, That's a Good Thing
ANN ARBOR--Employees seeking to boost their productivity at work should take a nap--yes, sleeping on the job can be a good thing. A new University of Michigan study finds that taking a nap may be an effective strategy to counteract impulsive behavior and to boost tolerance for frustration.
Old-school Literature Search Helps Ecologist Identify Puzzling Parasite
ANN ARBOR--A months-long literature search that involved tracking down century-old scientific papers and translating others from Czech and French helped University of Michigan ecologist Meghan Duffy answer a question she'd wondered about for years.
Below-average 'Dead Zone' Predicted for Chesapeake Bay in 2015
ANN ARBOR--A University of Michigan researcher and his colleagues are forecasting a slightly below-average but still significant "dead zone" this summer in the Chesapeake Bay, the nation's largest estuary. The 2015 Chesapeake Bay forecast calls for an oxygen-depleted, or hypoxic, region of 1.37 cubic miles, about 10 percent below the long-term average. The forecast was released today by the National Oceanic and Atmospheric Administration, which sponsors the work.
