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

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.

Tuberculosis: Daily Antibiotics Recommended to Prevent Resistant Strains
ANN ARBOR--A computer model of tuberculosis has shown that approved treatments prescribing antibiotic doses once or twice a week are more likely to lead to drug resistant strains than are daily antibiotic regimens. The finding, from a University of Michigan study, could help inform the treatment of the roughly 10 million people worldwide who fall ill with tuberculosis each year.
ADHD Meds May Be a Prescription for Bullying
ANN ARBOR--Kids and teens who take medications like Ritalin to treat attention-deficit hyperactivity disorder are twice as likely to be physically or emotionally bullied by peers than those who don't have ADHD, a new University of Michigan study found. At even higher risk were middle and high school students who sold or shared their medications--those kids were four-and-a-half times likelier to be victimized by peers than kids without ADHD.
Nationwide Look at Diabetes in Mexico Paints Grim Picture
ANN ARBOR -- If diabetes in Mexico continues unchecked, at least one in three people, and as many as one in two, could be diagnosed with the disease in their lifetimes.
Parasitic Fungi And the Battle Against Coffee Rust Disease
ANN ARBOR--Coffee rust has ravaged Latin American plantations for several years, leading to reductions in annual coffee production of up to 30 percent in some countries and threatening the livelihoods of hundreds of thousands of small-scale farmers in the region. A new study by University of Michigan researchers suggests that the coffee plants themselves may hold biological weapons that could someday be harnessed in the fight against the coffee rust fungal pathogen.
Sunscreen Ingredient May Prevent Medical Implant Infections
ANN ARBOR--A common ingredient in sunscreen could be an effective antibacterial coating for medical implants such as pacemakers and replacement joints. University of Michigan researchers found that a coating of zinc oxide nanopyramids can disrupt the growth of methicillin-resistant Staphylococcus aureus (MRSA), reducing the film on treated materials by over 95 percent. About a million implanted medical devices are infected each year with MRSA and other bacterial species.
Search-and-rescue Proteins Find, Fix DNA Mutations Linked to Cancer
ANN ARBOR--Proteins inside bacteria cells engage in "search-and-rescue"-type behavior to ferret out mismatched DNA and fix it to thwart dangerous mutations that can be associated with certain cancers, a University of Michigan study found. It's long been known that the protein MutS can identify and fix DNA mismatches in the cells, but how it detected such rare events was unclear until now, said Lyle Simmons, U-M associate professor of molecular, cellular and developmental biology.
Low Testosterone, Men's Empathy Can Determine Parenting Skills
ANN ARBOR--As they age, men often get concerned about their testosterone levels dropping. And rightfully so--it affects their sex drive and other health factors. But the hormone decline can also provide a window into men's parenting.
Shift in Weaning Age Supports Hunting-induced Extinction of Siberian Woolly Mammoths
ANN ARBOR--Chemical clues about weaning age embedded in the tusks of juvenile Siberian woolly mammoths suggest that hunting, rather than climate change, was the primary cause of the elephant-like animal's extinction.
