More useful projections of sea level are possible despite substantial uncertainty about the future behavior of massive ice sheets, according to Princeton University researchers.
In two recent papers in the journals Nature Climate Change and the Proceedings of the National Academy of Sciences (PNAS), the researchers present a probabilistic assessment of the Antarctic contribution to 21st-century sea-level change. Their methodology folds observed changes and models of different complexity into unified projections that can be updated with new information. This approach provides a consistent means to integrate the potential contribution of both continental ice sheets — Greenland and Antarctica — into sea-level rise projections. (more…)
New Appliance, Software and Services Extend the IBM MobileFirst Strategy
LAS VEGAS – 29 Apr 2013: IBM’s Smarter Planet strategy took a major technological step forward today with the introduction of IBM MessageSight, a new appliance designed to help organizations manage and communicate with the billions of mobile devices and sensors found in systems such as automobiles, traffic management systems, smart buildings and household appliances.
Over the next 15 years, the number of machines and sensors connected to the Internet will explode. According to IMS Research, there will be more than 22 billion web-connected devices by 2020[i].These new devices will generate more than 2.5 quintillion bytes of new data every day[ii], while every hour enough information is consumed by Internet traffic to fill seven million DVDs.[iii](more…)
LAFAYETTE – Tiny sea creatures no bigger than a thumbtack are being credited for playing a key role in helping provide healthy habitats for many kinds of seafood, according to a new study by the Virginia Institute of Marine Science and U.S. Geological Survey.(more…)
When blessed with a resource in overwhelming abundance it’s generally a good idea to make valuable use of that resource. Lignocellulosic biomass is the most abundant organic material on Earth. For thousands of years it has been used as animal feed, and for the past two centuries has been a staple of the paper industry. This abundant resource, however, could also supply the sugars needed to produce advanced biofuels that can supplement or replace fossil fuels, providing several key technical challenges are met. One of these challenges is finding ways to more cost-effectively extract those sugars. Major steps towards achieving this breakthrough are being taken by researchers at the U.S. Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI).
“Through the tools of synthetic biology, we have engineered healthy plants whose lignocellulosic biomass can more easily be broken down into simple sugars for biofuels,” says Dominique Loque, who directs the cell wall engineering program for JBEI’s Feedstocks Division. “Working with the model plant, Arabidopsis, as a demonstration tool, we have genetically manipulated secondary cell walls to reduce the production of lignin while increasing the yield of fuel sugars.” (more…)
The invasive kudzu bug has the potential to be a major agricultural pest, causing significant damage to economically important soybean crops. Conventional wisdom has held that the insect pests will be limited to areas in the southern United States, but new research from North Carolina State University shows that they may be able to expand into other parts of the country.
Kudzu bugs (Megacopta cribraria) are native to Asia, and were first detected in the U.S. in Georgia in 2009. They have since expanded their territory as far north as Virginia. The bugs have an interesting life cycle, which has been thought to be a limiting factor on far they can spread. (more…)
To Robert Green, light contains more than meets the eye: it contains fingerprints of materials that can be detected by sensors that capture the unique set of reflected wavelengths. Scientists have used the technique, called imaging spectroscopy, to learn about water on the moon, minerals on Mars and the composition of exoplanets. Green’s favorite place to apply the technique, however, is right here on the chemically rich Earth, which is just what he and colleagues achieved this spring during NASA’s Hyperspectral Infrared Imager (HyspIRI) airborne campaign.
“We have ideas about what makes up Earth’s ecosystems and how they function,” said Green, of NASA’s Jet Propulsion Laboratory in Pasadena, Calif., who is principal investigator of the campaign’s Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) instrument. “But a comprehensive understanding requires us to directly measure these things and how they change over landscapes and from season to season.” (more…)
Winterthur exhibit showcases UD professor’s research on maps and culture
A new exhibit at Winterthur Museum highlights the research conducted by University of Delaware faculty member Martin Brückner, focusing on the important part that maps played in everyday American life from the 1750s to the 1870s.
“Common Destinations: Maps in the American Experience” opened Saturday, April 20, and will run through Jan. 5. Brückner, associate professor of English and of material culture studies at UD, was exploring what seemed to be an early American fascination with maps when he discovered that Winterthur’s collections included numerous examples of maps being used in daily life. He developed the idea for an exhibition from that discovery and his additional research. (more…)
