Science Bulletins: Full Gene Set Decoded for Three More People
In June 2000, scientists triumphantly announced they had deciphered the full human genome—the 3.2 billion units of DNA that make up the blueprint for human life. This sequence was a composite of smaller segments of DNA from many individuals, arranged to make one complete strand. Sequencing this genome cost billions of dollars and took more than a decade using the laboratory tools and techniques developed at the time. Since then, faster and cheaper sequencing techniques have been developed. Now
Science Bulletins: Ancient Graves Reveal Family Ties
In 2005, a team of archaeologists unearthed a well-preserved group of 4,600-year-old graves in the agricultural region of Eulau, Germany. People were buried three and four to a grave, an unmistakable stamp of the Corded Ware Culture, the earliest farmers in the region. Yet the intimate arrangement of the burials—some people were facing each other and had arms interlinked—prompted a deeper investigation.
DNA testing revealed that their orientation in death reflected an important connection i
Science Bulletins: Immune "Army" Can Fight HIV
Some people who contract the HIV virus stay healthy for decades. Scientists working towards HIV vaccines seek out these rare patients, who are called elite controllers. A recent study by researchers at the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, reveals one of the mechanisms behind their uncommon ability to ward off AIDS.
Science Bulletins: Mapping "Hobbit" History
The remains of a group of one-meter tall people who lived as recently as 12,000 years ago were found on the Indonesian island of Flores in 2003. Researchers have been examining the fossils ever since, seeking clues to where the Flores people fall on the human family tree and how they became so small. A new analysis by Kieran McNulty of the University of Minnesota and Karen Baab of Stony Brook University adds to growing agreement that these so-called "hobbits" were a distinct species of the Homo
Science Bulletins: Learning vs. Remembering: A Brain Battle ?
Our everyday affairs require many different brain functions that seem to occur simultaneously. Recently, neuroscientists from the University of Amsterdam and Duke University tested the human brain's ability to handle two tasks in quick succession: learning new information and recalling information already learned. Brain scans showed that a "switchboard" region in the frontal lobe seems responsible for fluidly and rapidly shifting between learning and remembering to avoid a bottleneck in our neu
Science Bulletins: Stomach Bacteria Show Early Human Travels
Evolutionary scientists are increasingly turning to an unusual tool to explore ancient human history: bacteria. Some microorganisms, like Helicobacter pylori, take up residence in our stomachs. Since they go where humans go—and undergo genetic changes along the way—they provide a way to track ancient human migration patterns. A study by a team of international researchers, recently published in the journal Science, shows how genetic investigation of H. pylori in modern-day East Asian and Pac
Science Bulletins: New Stem Cell Method Shows Promise
The University of Wisconsin-Madison researchers who turned ordinary skin cells into stem cells in 2007 have cleared a major safety concern of using those cells in research: their risk of cancer. Their previous process used a virus to insert several genes into the DNA of skin cells. The genetic code of these genes naturally reprograms cells to revert to their original stem cell state. There was just one problem—the new stem cells were cancer-prone.
The team's new method uses a different vehicl

EAHA Day 1 Session 1: Introduction To The Disaster Management Training Lecture
Universities in the Eastern Africa Region have come together to implement an initiative Health Emergency Management Program (HEMP) that will build the capacity of local governments in the region to manage and plan for response to major disasters of public health importance. The Eastern African Region is prone to many natural and technological disasters of different kinds. There is not one nation in the region that is not vulnerable to the devastating effects of these disasters. Many of these dis
Information Economics
Course provides a strong grounding in the economics of information goods and services. Students analyze strategic issues faced by for-profit and not-for-profit organizations: pricing, bundling, versioning, product differentiation and variety, network externalities, and rights management.
Seminar on Digital Libraries
SI 615 - This is a special topics seminar focusing on the current state of Ňdigital librariesÓ broadly defined. The seminar is multi-disciplinary in focus and in method, covering the history of the idea, its manifestation as projects and programs in academic, non-profit, and research settings, and the suite of policy issues that influence their development and growth. The concept of the digital library will serve as an intellectual construct within which to explore the related concepts of scho
Digital Government 1: Information Technology and Democratic Politics
SI 532 / SI 732 - Course is the first in a two-part sequence exploring contemporary practices, challenges, and opportunities at the intersection of information technology and democratic governance. Whereas the second course focuses on challenges and innovations in democratic administration, this first course focuses on theories and practices of democratic politics and the shifting role of information technologies in supporting, transforming, and understanding these.
