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.

Call of the Wild: Male Geladas Captivate Females with Moans, Yawns
ANN ARBOR -- For female gelada monkeys, a grunt from a male primate won't suffice to get her attention. The call of the wild must involve moans, wobbles or yawns to entice these females, according to a new University of Michigan study involving the Ethiopian mammals.
Nano-shells Deliver Molecules That Tell Bone to Repair Itself
ANN ARBOR--Scientists at the University of Michigan have developed a polymer sphere that delivers a molecule to bone wounds that tells cells already at the injury site to repair the damage. Using the polymer sphere to introduce the microRNA molecule into cells elevates the job of existing cells to that of injury repair by instructing the cells' healing and bone-building mechanisms to switch on, said Peter Ma, professor of dentistry and lead researcher on the project.
Flexible Film May Lead to Phone-sized Cancer Detector
ANN ARBOR--A thin, stretchable film that coils light waves like a Slinky could one day lead to more precise, less expensive monitoring for cancer survivors. The University of Michigan chemical engineers who developed the film say it could help patients get better follow-up treatment with less disruption to their everyday lives.
Magic Mold: Food Preservative Kills Cancer Cells, Superbugs
ANN ARBOR--Nisin, a naturally occurring food preservative that grows on dairy products, delivers a one-two punch to two of medicine's most lethal maladies: cancer and deadly, antibiotic-resistant bacteria. A new University of Michigan study found that feeding rats a "nisin milkshake" killed 70-80 percent of head and neck tumor cells after nine weeks and extended survival, said Dr. Yvonne Kapila, a professor at the University of Michigan School of Dentistry.
Asian Carp Could Cause Some Lake Erie Fish to Decline, Others to Increase
ANN ARBOR -- If they successfully invade Lake Erie, Asian carp could eventually account for about a third of the total weight of fish in the lake and could cause declines in most fish species -- including prized sport and commercial fish such as walleye, according to a new computer modeling study.
Turning Rice Farming Waste to Useful Silica Compounds
The researcher who developed the process says it could save approximately six tons of carbon emissions per ton of silica compounds produced. He estimates the cost of the technique to be 90 percent less than the current process, with virtually no carbon footprint. Developed by Richard Laine, a professor of materials science and engineering, the new technique is believed to be the first simple, inexpensive chemical method for producing high-purity silica compounds from agricultural waste.
Unhealthy Choices Cost Company Health Care Plans Billions of Dollars
ANN ARBOR--One out of every four dollars employers pay for health care is tied to unhealthy lifestyle choices or conditions like smoking, stress and obesity, despite the fact that most large employers have workplace wellness programs.
Heat Radiates 10,000 Times Faster at the Nanoscale
ANN ARBOR--When heat travels between two objects that aren't touching, it flows differently at the smallest scales--distances on the order of the diameter of DNA, or 1/50,000 of a human hair. While researchers have been aware of this for decades, they haven't understood the process. Heat flow often needs to be prevented or harnessed and the lack of an accurate way to predict it represents a bottleneck in nanotechnology development.
