...s to hundreds of years. Gene and enhancer trapping remove the need to produce mutant plants and instead identify genes based solely on their activity patterns. These methods rely on the insertion of a foreign piece of DNA, called a "trap vector," at random throughout the genome. This trap vector has a uniqu...Fox Chase Cancer Center research shows kidney cancer can be diagnosed in urine
...the urine of 17 patients after they had surgery to remove the cancerous kidney. Mutated genes present in the urine prior to the kidney removal were not present in the urine after the kidney was removed. "This step in our research further supports the accuracy of this potential screening test but also demo...Derek R. Lovley receives 2004 Proctor & Gamble Award from American Society for Microbiology
...which is the use of microbes or other organisms to remove hazardous substances from an environment. In addition to iron, some anaerobic bacteria can use other metals, including gold and uranium, in their metabolism. Harnessing the ability of these microbes to reduce these substances to less-harmful forms ma...Virginia Center for Coal and Energy Research helps implement global climate change initiative

...study. With today's standard treatment, surgery to remove the tumor followed by chemotherapy, survival rates for late-stage ovarian cancer are 30 to 35 percent. Long-term, the researchers' quest for biomarkers may lead to better treatments by identifying specific proteins expressed by ovarian cancer that co...Scientists 'beef up' plant-dwelling bacteria to boost phytoremediation
...nts, and improve the performance of plants used to remove these contaminants from the environment," van der Lelie said. The next step will be to test the technique in poplar and willow trees, deep-rooting species already used in phytoremediation.
