Angelou encourages University community to be ‘a rainbow in the clouds’

Maya Angelou had a special message for the enthusiastic audience that came to hear the renowned Renaissance woman and civil rights activist speak during a sold-out event held Friday evening, Feb. 22, in the University of Delaware’s Bob Carpenter Center.

“I’m going to remind you that you have already been paid for,” Angelou said. “Whether you are white or black or of Asian or Spanish ancestry, gay or straight, you don’t have to apologize to history for anything.” (more…)

How a Microbial Biorefinery Regulates Genes

Digesting lignin, a highly stable polymer that accounts for up to a third of biomass, is a limiting step to producing a variety of biofuels. Researchers at Brown have figured out the microscopic chemical switch that allows Streptomyces bacteria to get to work, breaking lignin down into its constituent parts. (more…)

NASA’s Aquarius Sees Salty Shifts

The colorful images chronicle the seasonal stirrings of our salty world: Pulses of freshwater gush from the Amazon River’s mouth; an invisible seam divides the salty Arabian Sea from the fresher waters of the Bay of Bengal; a large patch of freshwater appears in the eastern tropical Pacific in the winter. These and other changes in ocean salinity patterns are revealed by the first full year of surface salinity data captured by NASA’s Aquarius instrument.

“With a bit more than a year of data, we are seeing some surprising patterns, especially in the tropics,” said Aquarius Principal Investigator Gary Lagerloef, of Earth & Space Research in Seattle. “We see features evolve rapidly over time.” (more…)

Researchers at North Carolina State University have developed a new type of nanoscale structure that resembles a “nano-shish-kebab,” consisting of multiple two-dimensional nanosheets that appear to be impaled upon a one-dimensional nanowire. However, the nanowire and nanosheets are actually a single, three-dimensional structure consisting of a seamless series of germanium sulfide (GeS) crystals. The structure holds promise for use in the creation of new, three-dimensional (3-D) technologies.

The researchers believe this is the first engineered nanomaterial to combine one-dimensional and two-dimensional structures in which all of the components have a shared crystalline structure. (more…)

USGS Estimates 162 Billion Short Tons of Recoverable Coal in the Powder River Basin

New basin-wide assessment of recoverable resources and reserves

The Powder River Basin of Wyoming and Montana contains about 162 billion short tons (BST) of recoverable coal from a total of 1.07 trillion short tons of in-place resources according to a new USGS assessment. This assessment also estimates that 25 BST of those resources are currently economical to recover, the first such estimate released by the USGS for coal for an entire basin.

The Powder River Basin—a large geologic feature located in northeastern Wyoming and southeastern Montana—contains the largest deposits of low-sulfur subbituminous coal in the world. This study is significant because it illustrates that only a relatively small percentage of in-place coal resources are technically and economically recoverable. (more…)

Yammer Announces Message Translation to Ignite Multilingual Collaboration

Uses Microsoft Translator technology to support 39 languages.

SAN FRANCISCO — Feb. 28, 2013 — Yammer, Inc., a best-in-class Enterprise Social Network and part of the Microsoft Office Division, today announced plans to add message translation capabilities, which will allow users to instantly translate Yammer conversations into their native languages.

“Removing language as a barrier to cross-company collaboration can be a competitive game changer for multinational organizations. It opens a world of possibilities,” said Adam Pisoni, Yammer co-founder and general manager of Engineering, Microsoft Office Division. “This is another example of Yammer’s accelerated innovation following the Microsoft acquisition — we’re able to use Microsoft Translator to quickly deliver additional value to customers.” (more…)

How a ‘motor mouth’ is changing dentistry

If you want your dental fillings, crowns, implants, and so on to last, you can thank ART.

Chewing involves some of the human body’s most complex motions, and ART, the artificial mouth at the University of Minnesota School of Dentistry, can perform a year’s worth of chewing—300,000 cycles—in just a day or two. (more…)
