In the world, there are a lot of small molecules people would like to get rid of, or at least convert to something useful, according to University of Wisconsin-Madison chemist Robert J. Hamers. Think carbon dioxide, the greenhouse gas most responsible for far-reaching effects on global climate. Nitrogen is another ubiquitous small-molecule gas that can be transformed into the valuable agricultural fertilizer ammonia. Plants perform the chemical reduction of atmospheric nitrogen to ammonia...

Transplantation of human stem cells in an experiment conducted at the University of Wisconsin-Madison improved survival and muscle function in rats used to model ALS, a nerve disease that destroys nerve control of muscles, causing death by respiratory failure. ALS (amyotrophic lateral sclerosis) is sometimes called "Lou Gehrig's disease." According to the ALS Association, the condition strikes about 5,600 Americans each year. Only about half of patients are alive three years after...

Thinking 'Big' May Not Be The Best Way To Save Large-river Fish
2013-05-23 13:57:04

University of Wisconsin-Madison Large-river specialist fishes – from giant species like paddlefish and blue catfish, to tiny crystal darters and silver chub – are in danger, but researchers say there is greater hope to save them if major tributaries identified in a University of Wisconsin-Madison study become a focus of conservation efforts. The study says 60 out of 68 U.S. species, or 88 percent of fish species found exclusively in large-river ecosystems like the...

Stem Cell Transplants Help Mice Regain Memory
2013-04-22 05:00:50

redOrbit Staff & Wire Reports - Your Universe Online Researchers at the University of Wisconsin-Madison have successfully transformed human embryonic stem cells into nerve cells that helped mice regain their memory and the ability to learn. Senior author Su-Chun Zhang, a professor of neuroscience and neurology at the university, said that he and his colleagues have for the first time demonstrated that human stem cells can implant themselves in the brain and heal neurological...

When it comes to delivering genes to living human tissue, the odds of success come down the molecule. The entire therapy – including the tools used to bring new genetic material into a cell – must have predictable effects. Now, a new screening process will simplify non-viral transfection, providing a method researchers and clinicians use to find an optimal set of biomaterials to deliver genes to cells. Developed by William Murphy, the Harvey D. Spangler professor of...

For the first time, scientists have transplanted neural cells derived from a monkey's skin into its brain and watched the cells develop into several types of mature brain cells, according to the authors of a new study in Cell Reports. After six months, the cells looked entirely normal, and were only detectable because they initially were tagged with a fluorescent protein. Because the cells were derived from adult cells in each monkey's skin, the experiment is a proof-of-principle for the...

A multi-university team of researchers has artificially engineered a unique multilayer material that could lead to breakthroughs in both superconductivity research and in real-world applications. The researchers can tailor the material, which seamlessly alternates between metal and oxide layers, to achieve extraordinary superconducting properties – in particular, the ability to transport much more electrical current than non-engineered materials. The team includes experts from the...

Frank W. Waterstraat, Jr., RHIA, has been named director of the online healthcare information management degree program. In this role, he will help ensure the new UW health information management and technology degree program prepares graduates with the education and skills necessary to qualify for emerging jobs in this rapidly changing industry. Madison, Wis. (PRWEB) January 29, 2013 The health information technology revolution is shaping the healthcare industry in a profound way. The...

Trees and the insects that eat them wage constant war. Insects burrow and munch; trees deploy lethal and disruptive defenses in the form of chemicals. But in a warming world, where temperatures and seasonal change are in flux, the tide of battle may be shifting in some insects' favor, according to a new study. In a report published today (Dec. 31, 2012) in the Proceedings of the National Academy of Sciences, a team of scientists from the University of Wisconsin-Madison reports a rising...

Great Lakes Study Highlights Environmental Threats And Challenges
2012-12-18 09:46:53

April Flowers for redOrbit.com - Your Universe Online A research team, led by the University of Michigan, has developed a comprehensive map telling the story of human impact on the Great Lakes and identifying how "environmental stressors" stretching from Minnesota to Ontario are shaping the future of an ecosystem that contains 20 percent of the world's fresh water. The map, three years in the making, was a collaborative effort with the University of Wisconsin-Madison and a binational team...
