Surgeons at The Ohio State University Wexner Medical Center are the first in the U.S. to implant a new device designed to relieve knee pain and help prevent or delay the need for knee replacements in people with osteoarthritis. (more…)

ANN ARBOR — Simply making nanoparticles spin coaxes them to arrange themselves into what University of Michigan researchers call ‘living rotating crystals’ that could serve as a nanopump. They may also, incidentally, shed light on the origin of life itself.
The researchers refer to the crystals as ‘living’ because they, in a sense, take on a life of their own from very simple rules. (more…)
Pancreatic cancer is a particularly devastating disease. At least 94 percent of patients will die within five years, and in 2013 it was ranked as one of the top 10 deadliest cancers.
Routine screenings for breast, colon and lung cancers have improved treatment and outcomes for patients with these diseases, largely because the cancer can be detected early. But because little is known about how pancreatic cancer behaves, patients often receive a diagnosis when it’s already too late. (more…)
Almost one in 10 people will someday experience a kidney stone, which creates what is described as the most intense pain imaginable. This increasingly common condition leads to hundreds of thousands of surgeries in the United States each year.
A new device developed at the University of Washington would let doctors use ultrasound to move kidney stones inside the body and help them pass by natural means. (more…)
Splitting water into its components, two parts hydrogen and one part oxygen, is an important first step in achieving carbon-neutral fuels to power our transportation infrastructure – including automobiles and planes.
Now, North Carolina State University researchers and colleagues from the University of North Carolina at Chapel Hill have shown that a specialized coating technique can make certain water-splitting devices more stable and more efficient. Their results are published online in two separate papers in the Proceedings of the National Academy of Sciences. (more…)
Early in September Yale passed a milestone in mobile computing, with a record 39,414 mobile devices connected to its wireless networks. As on most college campuses the growth of mobile computing at Yale has been explosive, from well under 10,000 devices three years ago to almost 40,000 today.
A recent Gartner study showed that smartphone ownership among college students went from 55% in 2011 to 62% in 2012, and the percentage of students using their smartphones for academic work doubled in the same period. The typical U.S. college student now routinely uses between 2-3 wireless devices, and higher education computing experts predict that average to grow to 3-4 devices over the next year. (more…)
Using a “patient monitoring” device attached to a whale entangled in fishing gear, scientists showed for the first time how fishing lines changed a whale’s diving and swimming behavior. The monitoring revealed how fishing gear hinders whales’ ability to eat and migrate, depletes their energy as they drag gear for months or years, and can result in a slow death.
The scientists in this entanglement response suction-cupped a cellphone-size device called a Dtag to a two-year-old female North Atlantic right whale called Eg 3911. The Dtag, developed at Woods Hole Oceanographic Institution (WHOI), recorded Eg 3911’s movements before, during, and after at-sea disentanglement operations. (more…)
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.
Today’s ultrasound technology enables far more than glimpses into the womb. Doctors routinely use focused sound waves to blast apart kidney stones and prostate tumors, for example. The tools work primarily by focusing sound waves tightly enough to generate heat, says Jay Guo, a professor of electrical engineering and computer science, mechanical engineering, and macromolecular science and engineering. Guo is a co-author of a paper on the new technique published in the current issue of Nature’s journal Scientific Reports. (more…)
