Engineering Bacterial Live Wires
Berkeley Lab scientists discover the balance that allows electricity to flow between cells and electronics
Just like electronics, living cells use electrons for energy and information transfer. Despite electrons being a common “language” of the living and electronic worlds, living cells cannot speak to our largely technological realm. Cell membranes are largely to blame for this inability to plug cells into our computers: they form a greasy barrier that tightly controls charge balance in a cell. Thus, giving a cell the ability to communicate directly with an electrode would lead to enormous opportunities in the development of new energy conversion techniques, fuel production, biological reporters, or new forms of bioelectronic systems.

Space Station to Host New Cosmic Ray Telescope
UChicago’s Angela Olinto leads U.S. collaboration on international project
The National Aeronautics and Space Administration has awarded $4.4 million to a collaboration of scientists at five United States universities and NASA’s Marshall Space Flight Center to help build a telescope for deployment on the International Space Station in 2017.
The U.S. collaboration is part of a 13-nation effort to build the 2.5-meter ultraviolet telescope, called the Extreme Universe Space Observatory. UChicago Prof. Angela Olinto leads the U.S. collaboration. The telescope will search for the mysterious source of the most energetic particles in the universe, called ultra high-energy cosmic rays, from the ISS’s Japanese Experiment Module. The source of these cosmic rays has remained one of the great mysteries of science since physicist John Linsley discovered them more than 50 years ago. These cosmic rays consist of protons and other subatomic scraps of matter that fly through the universe at almost light speed. (more…)
NASA Rover Finds Conditions Once Suited for Ancient Life on Mars
PASADENA, Calif. –– An analysis of a rock sample collected by NASA’s Curiosity rover shows ancient Mars could have supported living microbes.
Scientists identified sulfur, nitrogen, hydrogen, oxygen, phosphorus and carbon — some of the key chemical ingredients for life — in the powder Curiosity drilled out of a sedimentary rock near an ancient stream bed in Gale Crater on the Red Planet last month.
“A fundamental question for this mission is whether Mars could have supported a habitable environment,” said Michael Meyer, lead scientist for NASA’s Mars Exploration Program at the agency’s headquarters in Washington. “From what we know now, the answer is yes.” (more…)
Big Bang Meets Big Data: South Africa Joins ASTRON and IBM to Build the Foundation for a New Era of Computing
South African scientists to develop rugged microservers to handle the harsh desert conditions, explore new computer architectures and develop advanced algorithms for radio astronomy imaging
Pretoria, South Africa – 11 Mar 2013: Square Kilometer Array (SKA) South Africa, a business unit of the country’s National Research Foundation is joining ASTRON, the Netherlands Institute for Radio Astronomy, and IBM in a four-year collaboration to research extremely fast, but low-power exascale computer systems aimed at developing advanced technologies for handling the massive amount of data that will be produced by the SKA, which is one of the most ambitious science projects ever undertaken.
The SKA is an international effort to build the world’s largest and most sensitive radio telescope, which is to be located in Southern Africa and Australia to help better understand the history of the universe. The project constitutes the ultimate Big Data challenge, and scientists must produce major advances in computing to deal with it. The impact of those advances will be felt far beyond the SKA project—helping to usher in a new era of computing, which IBM calls the era of cognitive systems. (more…)
The Vikings: Yale Historian Looks at the Myths vs. the History
As a lead-up to the forthcoming History Channel series “Vikings,” Tom Ashbrook, host of NPR’s “On Point,” talked with a foremost authority on the subject — Yale’s Anders Winroth — to de-mystify the legendary raiders of the North.
Winroth is professor and director of graduate studies in history. His most recently published book is “The Conversion of Scandinavia: Vikings, Merchants, and Missionaries in the Remaking of Northern Europe” (Yale University Press, 2011). His forthcoming volume, “A New History of the Viking Age,” will be published by Princeton University Press in 2014. YaleNews spoke with Winroth recently about some of the issues raised in his “On Point” interview. The following is an edited transcript. (more…)
Researchers ID Queens, Mysterious Disease Syndrome as Key Factors in Bee Colony Deaths
A new long-term study of honey bee health has found that a little-understood disease study authors are calling “idiopathic brood disease syndrome” (IBDS), which kills off bee larvae, is the largest risk factor for predicting the death of a bee colony.
“Historically, we’ve seen symptoms similar to IBDS associated with viruses spread by large-scale infestations of parasitic mites,” says Dr. David Tarpy, an associate professor of entomology at North Carolina State University and co-author of a paper describing the study. “But now we’re seeing these symptoms – a high percentage of larvae deaths – in colonies that have relatively few of these mites. That suggests that IBDS is present even in colonies with low mite loads, which is not what we expected.” The study was conducted by researchers from NC State, the University of Maryland, Pennsylvania State University and the U.S. Department of Agriculture (USDA).

News Websites Should Target “Reward Seekers”, MU Researcher Finds
Website designers should strive for simplicity, invoke emotion to boost online revenue
As newspaper sales continue to decline, many news organizations are searching for ways to improve readership and revenues from their online presences. Now, University of Missouri researchers have found that news organizations should target readers with certain personality traits in order to optimize their online viewership. Paul Bolls, an associate professor of strategic communication at the MU School of Journalism and a 2011-2012 MU Reynolds Journalism Institute Fellow, has found that news consumers who have “reward-seeking” personalities are more likely to read their news online and on mobile devices, and to engage with websites, by leaving comments on stories and uploading user-generated content.
In a study accepted for presentation at the 2013 International Communication Association conference in June, Bolls surveyed more than 1000 respondents and placed them into two personality groups: reward seekers and threat avoiders. He found that reward seekers tend to use the Internet liberally, searching out entertainment and gratification, while threat avoiders tend to be more conservative, looking only for information that directly affects them. Bolls found that respondents identified as reward seekers were much more likely to engage with news websites as well as more likely to use mobile devices such as smartphones and tablets to consume news. He says this knowledge should direct news organizations to target these reward seekers. (more…)
