Insight Public Sector selected to deliver licensing agreement aimed at reducing IT costs while offering advanced mobility, collaboration and cloud computing capabilities to personnel.
WASHINGTON, D.C. — Jan. 4, 2013 — In an effort to modernize technology infrastructure, reduce costs and foster new levels of cross-agency collaboration, the U.S. Army, U.S. Air Force and Defense Information Systems Agency (DISA) are expanding access to Microsoft solutions by entering into a transformative three-year Joint Enterprise Licensing Agreement for enterprise licenses and software assurance. The agreement provides all three organizations with a single vehicle for accessing the latest Microsoft technologies in support of top IT priorities around datacenter consolidation, collaboration, cybersecurity, mobility, cloud computing and big data.
This is the most comprehensive licensing agreement Microsoft Corp. has ever established with the U.S. Department of Defense (DoD), covering nearly 75 percent of all DoD personnel. The net new contract was awarded to Insight Public Sector, a division of Insight Enterprises Inc., one of the largest global Microsoft Large Account Resellers. (more…)
Workshop helps to define the human right to benefit from science
Conscience. Expression. Property. Fair trial. Peaceful assembly. And science?
Yes, says the University of Delaware’s Tom Powers, the international community has declared that there is an inalienable human right to science.
In 1948, the United Nations adopted the Universal Declaration of Human Rights, which guarantees in Article 27 “the right freely to participate in the cultural life of the community, to enjoy the arts and to share in scientific advancement and its benefits.”
The same right was reaffirmed by the U.N. General Assembly in Article 15 of the International Covenant on Economic, Social and Cultural Rights in 1966. (more…)
A new species of plant-eating dinosaur with tiny, 1-inch-long jaws has come to light in South African rocks dating to the early dinosaur era, some 200 million years ago.
This “punk-sized” herbivore is one of a menagerie of bizarre, tiny, fanged plant-eaters called heterodontosaurs, or “different toothed reptiles,” which were among the first dinosaurs to spread across the planet. (more…)
Washington, D.C. – For years, scientists have debated how big a role elephants play in toppling trees in South African savannas. Tree loss is a natural process, but it is increasing in some regions, with cascading effects on the habitat for many other species. Using high resolution 3-D mapping, Carnegie scientists have for the first time quantitatively determined tree losses across savannas of Kruger National Park. They found that elephants are the primary agents—their browsing habits knock trees over at a rate averaging 6 times higher than in areas inaccessible to them. The research also found that elephants prefer toppling trees in the 16-to-30 foot (5-8 m) range, with annual losses of up to 20% in these height classes. The findings, published in Ecology Letters, bolster our understanding of elephant conservation needs and their impacts, and the results could help to improve savanna management practices.
“Previous field studies gave us important clues that elephants are a key driver of tree losses, but our airborne 3-D mapping approach was the only way to fully understand the impacts of elephants across a wide range of environmental conditions found in savannas,” commented lead author Greg Asner of Carnegie’s Department of Global Ecology. “Our maps show that elephants clearly toppled medium-sized trees, creating an “elephant trap” for the vegetation. These elephant-driven tree losses have a ripple effect across the ecosystem, including how much carbon is sequestered from the atmosphere.” (more…)
For the first time, the U.S. Food and Drug Administration is considering approving a drug that helps prevent someone from acquiring HIV. It’s called Truvada, and has been approved for use since 2004 to treat infected people.
Now it has been shown to protect healthy people who are exposed to HIV. The UW’s International Clinical Research Center, within the Department of Global Health, played a key role in examining the drug’s effectiveness for HIV prevention.
Researchers Connie Celum and Jared Baeten led a study, published this week in the New England Journal of Medicine, of pre-exposure prophylaxis among heterosexual couples in Kenya and Uganda. One partner had HIV (and was not yet eligible for HIV treatment) and the other partner did not have HIV. Uninfected partners were given either Truvada or Tenofovir (both antiretroviral drugs) or a placebo. (more…)
*Discovery of partial foot skeleton could mean hominin species lived side by side*
A new fossil discovery from Eastern Africa called the Burtele foot indicates Australopithecus afarensis, an early relative of modern humans, may not have been the only hominin to walk the plains and woodlands of what is now the Afar region of Ethiopia some 3.4 million years ago.
Researchers openly have questioned whether Au. afarensis, the species to which the famous fossil “Lucy” belongs, was the only living hominin during the late Pliocene of Africa. Lucy’s bones provided evidence that she and perhaps other early hominins may have walked upright, but whether or not she was the sole hominin species in her particular geologic time scale has been the subject of much debate.
