For people whose hands shake uncontrollably due to a medical condition, just eating can be a frustrating and embarrassing ordeal, enough to keep them from sharing a meal with others. But a small new study conducted at the Univ. of Michigan Health System suggests that a new handheld electronic device can help such patients overcome the hand shakes caused by essential tremor, the most common movement disorder.

A brain stimulation technique that is used to treat tough cases of depression could be considerably improved with a new headpiece designed by Univ. of Michigan engineers. Computer simulations showed that the headpiece—a square array of 64 circular metallic coils—could one day help researchers and doctors hit finer targets in the brain that are twice as deep as they can reach today, and without causing pain.
Structures that put a spin on light reveal tiny amounts of DNA with 50 times better sensitivity than the best current methods, a collaboration between the Univ. of Michigan and Jiangnan Univ. in China has shown. Highly sensitive detection of DNA can help with diagnosing patients, solving crimes and identifying the origins of biological contaminants such as a pathogen in a water supply.
If recent trends continue, auto companies should be able to meet new federal fuel economy standards over the next 12 years, say Univ. of Michigan researchers. A year after the EPA and the National Highway Traffic Safety Administration announced the final standard governing new-vehicle Corporate Average Fuel Economy (CAFE) for model years 2017-2025, CAFE performance has exceeded anticipated levels for 2012 and 2013.
A global hunt for genes that influence heart disease risk has uncovered 157 changes in human DNA that alter the levels of cholesterol and other blood fats—a discovery that could lead to new medications. Each of the changes points to genes that can modify levels of cholesterol and other blood fats and are potential drug targets.
A microfluidic chip developed at the Univ. of Michigan is among the best at capturing elusive circulating tumor cells from blood—and it can support the cells' growth for further analysis. The device, believed to be the first to pair these functions, uses the advanced electronics material graphene oxide. In clinics, such a device could one day help doctors diagnose cancers.
Coal soot shrank the Alpine glaciers in mid-19th-century Europe, according to new findings that show how black carbon alone, even without warmer temperatures, can affect ice and snow cover. The research provides insights into when the so-called Little Ice Age ended and why European glaciers began to retreat decades before global temperatures rose.
Darwin referred to the origin of species as "that mystery of mysteries," and even today, more than 150 years later, evolutionary biologists cannot fully explain how new animals and plants arise. For decades, nearly all research in the field has been based on the assumption that the main cause of the emergence of new species, a process called speciation, is the formation of barriers to reproduction between populations. Until now.
The law that has helped medical discoveries make the leap from university labs to the marketplace for more than 30 years needs revising, according to Univ. of Michigan doctor has taken another look at the history of Bayh-Dole. He says that the Supreme Court ruling on gene patenting, and modern risks raised by industry/academic interaction, signal a need for change.
High Performance Electrostatic Comb-drive Micro-Actuators developed by the Univ. of Michigan make use of fundamentally new flexure mechanisms for actuator guidance, which mitigates sideways instability in electrostatic comb-drive actuators.
A fungus and E. coli bacteria have joined forces to turn tough, waste plant material into isobutanol, a biofuel that matches gasoline's properties better than ethanol. Univ. of Michigan research team members said the principle also could be used to produce other valuable chemicals such as plastics.
The hospital IT networks and medical devices that doctors rely on to treat patients are susceptible to their own maladies: computer viruses and other malware. Whether a bug accidentally finds its way into a system, or an attacker intentionally injects one, researchers believe such breaches are happening more often with the growth of technology such as cloud computing. A national team is at work to improve the cybersecurity of these systems.
The U.S. uses more energy for air conditioning (AC) than all other countries combined; but its status as the world's largest AC energy hog may soon be in jeopardy, said a Univ. of Michigan researcher. A study shows that if the rest of the world adopts the same AC usage patterns found in the U.S., and more and more countries certainly are, eight nations have the potential to surpass the American yardstick of high air-conditioning use.
The next generation of smartphones could be capable of storing 250 hours of high-definition video and carrying a charge for a week, thanks to an advanced data storage technology from a Univ. of Michigan startup that could upend the memory market. Crossbar Inc., which licensed the technology from U-M in 2010, recently announced it has developed a working resistive random access memory prototype in a commercial fabrication facility.
If the mission sounds impossible, that's because it is—at least with today's technology: Build a three-pound flying machine that can, under its own control, take off, fly through a window into a model building, avoid security lasers, navigate the halls, recognize signs, enter the correct room, find a flash drive in a box on a desk, pick it up, leave a decoy, exit and land in under 10 min.
A team of Univ. of Michigan researchers has been awarded a $2 million federal grant to identify and test naturally diverse groups of green algae that can be grown together to create a high-yield, environmentally sustainable and cost-effective system to produce next-generation biofuels.
Nanoscientists who recently created beautiful, tiled patterns with flat nanocrystals faced a mystery: Why did crystals arrange themselves in an alternating, herringbone style, even though it wasn’t the simplest pattern? Help from computer simulations have given them a new tool for controlling how objects one-millionth the size of a grain of sand arrange themselves into useful materials.
In events that could exacerbate sea level rise over the coming decades, stretches of ice on the coasts of Antarctica and Greenland are at risk of rapidly cracking apart and falling into the ocean, according to new iceberg calving simulations from the Univ. of Michigan.
Flexible electronics have a wide variety of possibilities, from bendable displays and batteries to medical implants that move with the body. Networks of spherical nanoparticles embedded in elastic materials may make the best stretchy conductors yet, engineering researchers at the Univ. of Michigan have discovered.
Two Univ. of Michigan engineering professors are turning to the Kickstarter online community to help fund an interplanetary satellite mission. They are teaming up to create two new technologies in a matter of months, with the goal of using a plasma thruster to push a CubeSat into deep space—something that has never been done before.
In an apple seed-sized pellet of glass, Univ. of Michigan engineering researchers have packed seven devices that together could potentially provide navigation in the absence of the satellite-based Global Positioning System (GPS.) Space-based GPS is far from fail-proof. It doesn't work indoors, near tall buildings or in heavy cloud cover; and it's relatively easy to jam, researchers say.
Half a millennium after Johannes Gutenberg printed the Bible, researchers printed a 3-D splint that saved the life of an infant born with severe tracheobronchomalacia, a birth defect that causes the airway to collapse. While similar surgeries have been performed using tissue donations and windpipes created from stem cells, this is the first time 3-D printing has been used to treat tracheobronchomalacia—at least in a human.
A Univ. of Michigan researcher worked with Univ. of Utah colleagues to develop a new weapon to fight poachers who kill elephants, hippos, rhinos and other wildlife. By measuring radioactive carbon-14 deposited in tusks and teeth following open-air nuclear bomb tests, the method reveals the year an animal died, and thus whether the ivory was taken illegally.
A new laser that can show what objects are made of could help military aircraft identify hidden dangers such as weapons arsenals far below. The system, which is made of off-the-shelf telecommunications technology, emits a broadband beam of infrared light. While most lasers emit light of one wavelength, or color, super-continuum lasers like this one give off a tight beam packed with columns of light covering a range of wavelengths.
In findings that could help overcome a major technological hurdle in the road toward smaller and more powerful electronics, an international research team involving Univ. of Michigan engineering researchers, has shown the unique ways in which heat dissipates at the tiniest scales.
Making cars more fuel-efficient is great for reducing greenhouse gas emissions, but rather than promoting sales of electric and other alternative-fuel vehicles, policymakers should turn their focus to cutting emissions in other energy sectors—from oil wells and power plants to farms and forests affected by biofuels production—says a Univ. of Michigan researcher.
