Novel Enzyme Offers New Look At Gene Regulation Scientists at the University of North Carolina at Chapel Hill have purified a novel protein and have shown it can alter gene activity by reversing a molecular modification previously thought permanent. 'Benign' MS May Not Be So Benign People who have multiple sclerosis (MS) for 10 years and have few of the disabling symptoms of the disease are often told they have "benign MS"and that their symptoms will likely not ever occur to the same extent as other people with MS. A new study, published in the Feb. 13, 2007, issue of Neurology, the scientific journal of the American Academy of Neurology, shows that unfortunately this may not be correct. NASA's Rovers Continue Martian Missions NASA's Mars rover Opportunity is trying to escape from a sand trap, while its twin, Spirit, has been busy finding new clues to a wet and violent early Martian history. Employees Bring Bad Moods Home, But They Disappear By Morning A good night's sleep may be the remedy for a bad day at work, suggests a new University of Florida study on the unexplored relationship between job satisfaction and the shifting moods of employees. Prototype Indoor Climate System Enables User To Control Personal Envir Syracuse, N.Y.-based company CollabWorx Inc. and collaborators from the Syracuse Center of Excellence in Environmental and Energy Systems (Syracuse CoE) and Syracuse University have developed a working prototype of an indoor climate control system that has the ability to make "smart"decisions in response to changing conditions within an office or building based on interaction with the human occupants. Significant Reduction In Blood Pressure With Implantable Device System A device first implanted in the United States at the University of Rochester Medical Center as part of a clinical trial is showing a significant reduction in blood pressure in patients who suffer from severe hypertension and cannot control their condition with medications or lifestyle changes. Trail of Tears: National Historic Trail Material about this trail that "commemorate[s] the survival of the Cherokee people despite their forced removal from their homelands in the Southeastern United States in the 1840s."The site features an interactive map of the trail that covers "2,200 miles of land and water routes, and traverses portions of nine states,"reports on research projects, a link to a lesson plan, and related material. From the National Park Service (NPS). Global Strategy For Investigating Earth's Geodynamics Emerges From Int Fifty-one researchers, prominent Earth scientists representing 15 countries, gathered recently in Switzerland to forge a global strategy for advancing understanding of continental rifting and continental break-up through the use of a new array of multiple drilling platforms provided by the Integrated Ocean Drilling Program. The group's emerging plan is discussed in an article in the November 14 edition of Eos. Human Induced Pluripotent Stem Cells Retain Some Gene Expression Of Do A team of researchers has developed a safe strategy for reprogramming cells to a pluripotent state without use of viral vectors or genomic insertions. Their studies reveal that these induced pluripotent stem cells (iPSCs) are very similar to human embryonic stem cells, yet maintain a "transcriptional signature." Yucca Mountain: Putting A Limit On Risk Looking ahead 100 million years, new research puts a maximum limit of 3.6 meters per second on potential ground movement caused by earthquakes at Yucca Mountain, Nevada, the site of the proposed high-level radioactive waste repository. Yucca Mountain has unique characteristics that make it arguably the best location to store hazardous waste, chiefly a water table so low that it is possible to store steel canisters of waste 1000 feet below ground and 1000 feet above the water table. Two questions form the current debate: how dry will the site remain, and what is the risk from earthquakes?
