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.
Ever been to a whispering gallery—a quiet, circular space underneath an old cathedral dome that captures and amplifies sounds as quiet as a whisper? Researchers at the University of Illinois at Urbana-Champaign and the University of Michigan are applying similar principles in the development optomechanical sensors that will help unlock vibrational secrets of chemical and biological samples at the nanoscale.
Transportation crashes have accounted for two-thirds of U.S. noncombat military deaths since 2000—a trend Univ. of Michigan researchers are hoping to help reverse. Research Prof. Matthew Reed and colleagues at the U-M Transportation Research Institute and U.S. Army Tank Automotive Research, Development and Engineering Center (TARDEC) aim to make seating in military vehicles safer, more effective and more comfortable for soldiers.
Zebrafish with very weak muscles helped scientists decode the elusive genetic mutation responsible for Native American myopathy, a rare, hereditary muscle disease that afflicts Native Americans in North Carolina. Scientists originally identified the gene in mutant zebrafish that exhibited severe muscle weakness. The responsible gene encodes for a muscle protein called Stac3.
High-performance thermoelectric materials that convert waste heat to electricity could one day be a source of more sustainable power. But they need to be a lot more efficient before they could be effective on a broad scale in places like power plants or military bases, researchers say. A University of Michigan researcher has taken a step toward that goal.
Health care spending is much higher for older Americans than for younger adults and children, on average, and analysts have said that increasing spending leads to longer life expectancy. But new research from the University of Michigan indicates that aging populations could view things differently.
You're standing near an airport luggage carousel and your bag emerges on the conveyor belt, prompting you to spring into action. How does your brain make the shift from passively waiting to taking action when your bag appears? A new study from investigators at the University of Michigan and Eli Lilly may reveal the brain's "switch" for new behavior.
Engineering researchers at the University of Michigan have demonstrated a paradigm-shifting "polariton" laser that's fueled not by light, but by electricity. Polaritons are particles that are part light, and part matter. The new device requires at least 1,000 times less energy to operate, compared with a conventional laser.
Most Michigan and Pennsylvania residents say fracking is good for the economy, but have concerns about chemicals used and other environmental risks, according to a University of Michigan survey. Fracking is the common term for hydraulic fracturing, which involves injecting a mixture of water, sand, and chemicals deep into the ground through encased wells at high pressure to create and expand fractures in the shale rock.
