Scientists have discovered a new source of stems cells and have used them to create muscle, bone, fat, blood vessel, nerve and liver cells in the laboratory. The first report showing the isolation of broad potential stem cells from the amniotic fluid that surrounds developing embryos was published today in Nature Biotechnology.
The Canadian Food Inspection Agency (CFIA) recently gave preliminary approval for field use of the world’s first vaccine to reduce Escherichia coli O157:H7 in cattle and thereby help keep it out of food.
Recent studies report that 4% of novice nurses in Japan quit within nine months on the job, while 8.5% quit within one year.
Research has shown that serum tests work effectively as a pre-screening method for atrophic gastritis and gastric cancer. These tests will foster the detection rate of early cancer in patients ? providing not only a far less invasive examination as compared to the conventional scope method, but also give patients a cheap, convenient and safe alternative.
MR imaging can make a dramatic difference in the management of patients with ankle pain, changing treatment in about one-third of the patients, a new study finds.
While millions of Americans place fitness as one of their top New Year’s resolutions to improve shape, muscle tone and overall appearance, cancer survivors have another priority — life.
Understanding the differences among drivers in different gender and age categories is crucial to preventing serious injuries, said researchers in a new study showing stark statistical differences in traffic-accident injuries depending on the gender and age of drivers.
For the first time ever, researchers at the U.S. Department of Energy’s Ames Laboratory have developed a material with a negative refractive index for visible light. Ames Laboratory senior physicist Costas Soukoulis, working with colleagues in Karlsruhe, Germany, designed a silver-based, mesh-like material that marks the latest advance in the rapidly evolving field of metamaterials, materials that could lead to a wide range of new applications as varied as ultrahigh-resolution imaging systems and cloaking devices.
A first of its kind study by a researcher in the University of Georgia School of Social Work finds that repeatedly hearing the stories of trauma victims doubles the risk of social workers themselves experiencing post-traumatic stress disorder.
Prof Michael King of the University of Rochester has invented a device that filters the blood for cancer and stem cells. When he captures cancer cells, he kills them. When he captures stem cells, he harvests them for later use in tissue engineering, bone marrow transplants, and other health applications. This is a non-controversial way of obtaining stem cells that can be differentiated into other, useful cells.
