The U.S. has long been among the world's worst emitters of carbon dioxide, but when accounting for climate in addition to GDP, it is nowhere near the bottom of that list, according to University of Michigan researchers.
For the second straight month, fuel economy of all new vehicles sold in the United States fell by 0.2 mpg—likely reflecting a slight drop in gas prices, say researchers at the University of Michigan Transportation Research Institute.
University of Michigan researchers have proven that a special surface, free of biological contaminants, allows adult-derived stem cells to thrive and transform into multiple cell types. Their success brings stem cell therapies another step closer.
U.S. factories produce about 75% of what the country consumes, but the right decisions by both business and political leaders could push that to 95%, say University of Michigan researchers.
Popular firewall technology designed to boost security on cellular networks can backfire, unwittingly revealing data that could help a hacker break into Facebook and Twitter accounts, a new study from the University of Michigan shows. The researchers also developed an Android app that tells phone users when they're on a vulnerable network.
Text messaging is a surprisingly good way to get candid responses to sensitive questions, according to a new study to be presented at the annual meeting of the American Association for Public Opinion Research.
A hidden facet of a math problem that goes back to Sanskrit scrolls has just been exposed by nanotechnology researchers, who say we've been missing a version of the famous "packing problem,” which seeks the best way to cover the inside of an object with a particular shape.
Researchers at the University of Michigan have identified new targets for drugs that could potentially treat anthrax, the deadly infection caused by Bacillus anthracis . The team found a new way to block the bacteria's ability to capture iron, which is vital to its survival and its disease-causing properties.
Portable gas sensors can allow you to search for explosives, diagnose medical conditions through a patient's breath, and decide whether it's safe to stay in a mine. These devices do all this by identifying and measuring airborne chemicals, and a new, more sensitive, smart model is under development at the University of Michigan.
Fuel economy of all new vehicles sold in the United States has topped 24 mpg for the first time ever, say researchers at the University of Michigan Transportation Research Institute.
Researchers from the University of Michigan Health System and the Massachusetts Institute of Technology report they have created the first full 3-D images of B12 and its partner molecules twisting and contorting as part of a crucial reaction called methyltransfer. The reaction is crucial to biological systems and has implications for fuel development.
A University of Michigan cell biologist and his colleagues have identified a potential drug that speeds up trash removal from the cell's recycling center, the lysosome. The finding suggests a new way to treat rare inherited metabolic disorders and common neurodegenerative diseases.
Scientists from the Chinese Academy of Science's Shanghai Institute of Ceramics, in collaboration with scientists from Brookhaven National Laboratory, the University of Michigan, and the California Institute of Technology, have identified a new class of high-performance thermoelectric materials. In their study, liquid-like copper ions carry electric current around a solid selenium crystal lattice.
Nerve gases are colorless, odorless, tasteless, and deadly. While today's soldiers carry masks and other protective gear, they don't have reliable ways of knowing when they need them in time. That could change, thanks to a new litmus-like paper sensor made at the University of Michigan, which are designed to change color from blue to pink within 30 sec of exposure to trace amounts of nerve gas.
A new power scheme for cardiac pacemakers turns to an unlikely source: vibrations from heartbeats themselves. Engineering researchers at the University of Michigan designed a device that harvests energy from the reverberation of heartbeats through the chest and converts it to electricity to run a pacemaker or an implanted defibrillator.
Computational sprinting is a new approach to smartphone power and cooling that could give users dramatic, brief bursts of computing capability to improve current applications and make new ones possible. Its developers at the University of Pennsylvania and the University of Michigan are pushing mobile chips beyond their sustainable operating limits, much like a sprinter who runs extremely fast for a relatively short distance.
The fastest wind ever discovered blowing off a disk around a stellar-mass black hole has been observed by a team of astronomers. Using NASA's Chandra X-ray Observatory they clocked the record-breaking super wind at about 20 million mph, or about 3% of the speed of light.
An energy-recycling computer circuit born at the University of Michigan will enable a new generation of power-efficient laptop PCs and servers. Advanced Micro Devices (AMD) announced that the company's forthcoming 64-bit processor core, dubbed Piledriver, incorporates the technology.
The United States Air Force Office of Scientific Research has awarded $8.5 million to a consortium of seven U.S. universities that will work together to determine the best approach for generating quantum memories based on interaction between light and matter. The team will consider three different approaches for creating entangled quantum memories that could facilitate the long-distance transmission of secure information.
The University of Michigan's first human embryonic stem cell line will be placed on the U.S. National Institutes of Health's registry, making the cells available for federally funded research. It is the first of the stem cell lines derived at the University of Michigan to be placed on the registry.
Using a liquid laser, University of Michigan researchers have developed a better way to detect the slight genetic mutations that might predispose a person to a particular type of cancer or other diseases. The work could advance understanding of the genetic basis of diseases.
Why is the universe magnetized? It's a question scientists have been asking for decades. Now, an international team of researchers including a University of Michigan professor have demonstrated that it could have happened spontaneously, as the prevailing theory suggests.
A new University of Michigan computer model of disease transmission in space and time can predict cholera outbreaks in Bangladesh up to 11 months in advance, providing an early warning system that could help public health officials there.
Astronomers have detected a mysterious ring of carbon monoxide gas around the young star V1052 Cen, which is about 700 light years away in the southern constellation Centaurus. The ring is part of the star's planet-forming disk, and it's as far from V1052 Cen as Earth is from the sun. Discovered with the European Southern Observatory's Very Large Telescope, its edges are uniquely crisp.
After two months of increases, the average fuel economy of all new vehicles sold in the United States fell by a half mile per gallon last month, say researchers at the University of Michigan Transportation Research Institute.
