MADISON -- A new model of the Earth, 20 years in the making, describes a dynamic three-dimensional puzzle of planetary proportions. Created by University of Wisconsin-Madison geophysicist Chuck DeMets and longtime collaborators Richard Gordon of Rice University and Donald Argus of NASA's Jet Propulsion Laboratory, the model offers a precise description of the relative movements of 25 interlocking tectonic plates that account for 97 percent of the Earth's surface. "This model can be...

Materials scientists at the University of Wisconsin-Madison have designed a way to harvest small amounts of waste energy and harness them to turn water into usable hydrogen fuel. The process is simple, efficient and recycles otherwise-wasted energy into a useable form. "This study provides a simple and cost-effective technology for direct water splitting that may generate hydrogen fuels by scavenging energy wastes such as noise or stray vibrations from the environment," the authors write in a...

Exerting delicate control over a pair of atoms within a mere seven-millionths-of-a-second window of opportunity, physicists at the University of Wisconsin-Madison created an atomic circuit that may help quantum computing become a reality. Quantum computing represents a new paradigm in information processing that may complement classical computers. Much of the dizzying rate of increase in traditional computing power has come as transistors shrink and pack more tightly onto chips "” a...

A team of University of Wisconsin-Madison engineers has developed a highly efficient, environmentally friendly process that selectively converts gamma-valerolactone, a biomass derivative, into the chemical equivalent of jet fuel. The simple process preserves about 95 percent of the energy from the original biomass, requires little hydrogen input, and captures carbon dioxide under high pressure for future beneficial use. With James Dumesic, Steenbock Professor of Chemical and Biological...

MADISON -- Genetic interactions between avian H5N1 influenza and human seasonal influenza viruses have the potential to create hybrid strains combining the virulence of bird flu with the pandemic ability of H1N1, according to a new study. In laboratory experiments in mice, a single gene segment from a human seasonal flu virus, H3N2, was able to convert the avian H5N1 virus into a highly pathogenic form. The findings are reported the week of Feb. 22 in the online early edition of the...

Unique program analyzes time-lapse images to identify changes in cell behaviors A software program created by an engineer at the University of Wisconsin"“Milwaukee (UWM) can not only predict the types of specialized cells a stem cell will produce, but also foresee the outcome before the stem cell even divides. The software, developed by Andrew Cohen, an assistant professor of electrical engineering, analyzes time-lapse images capturing live stem cell behaviors. It will allow scientists...

The great promise of induced pluripotent stem cells is that the all-purpose cells seem capable of performing all the same tricks as embryonic stem cells, but without the controversy. However, a new study published this week (Feb. 15) in the Proceedings of the National Academy of Sciences comparing the ability of induced cells and embryonic cells to morph into the cells of the brain has found that induced cells "” even those free of the genetic factors used to program their all-purpose...

EAU CLAIRE, Wis., Feb. 10 /PRNewswire/ -- With increasing attention being paid to marketing accountability, firms must justify their advertising expenditures with financial results. Drs. Rama Yelkur and Chuck Tomkovick, marketing professors at the University of Wisconsin-Eau Claire, present a study of Olympic advertisers who ran ads on NBCU's broadcasts of the 2000, 2002, 2004, 2006 and 2008 Olympic Games. All publicly traded firms that ran ads during those Olympics telecasts were...

The amount of time children spend in institutional care may affect how their brains develop. That's the conclusion of a new study carried out by researchers at the University of Wisconsin, Harvard Medical School/Children's Hospital Boston, and the University of Minnesota. The study is published in Child Development in the journal's January/February 2010 issue. To learn how the deprivation and neglect that institutionalized children often experience affect brain development, the researchers...

Your facial expression may tell the world what you are thinking or feeling. But it also affects your ability to understand written language related to emotions, according to research that was presented Jan. 29 to the Society for Personal and Social Psychology in Las Vegas, and will be published in the journal Psychological Science. The new study reported on 40 people who were treated with botulinum toxin, or Botox. Tiny applications of this powerful nerve poison were used to deactivate...
