Join the team that is performing the largest, most diverse and technically complex environmental cleanup programs in the world.

Fifty years of nuclear weapons production and energy research generated millions of gallons of radioactive waste, thousands of tons of spent nuclear fuel and special nuclear material, along with huge quantities of contaminated soil and water. The Department of Energy's Office of Environmental Management was established to clean up the legacy waste and environmental contamination from these operations. We are doing it in a manner safe for workers, protective of the environment, and respectful to the taxpayer. The program includes responsibility for the cleanup of 108 contaminated nuclear weapons manufacturing and testing sites across the United States. Specified in that responsibility is the need to:

* Safely disposition large volumes of nuclear wastes;
* Safeguard materials that could be used in nuclear weapons; and,
* Deactivate and decommission several thousand contaminated facilitates no longer needed to support the Departments' mission and remediate extensive surface and groundwater contamination.

Researchers at the University of Zaragoza and Consejo Superior de Investigaciones Científicas (CSIC) have made new findings from the project ROSAS, dedicated to the study of free radicals - responsible, among other things, the aging celulary by extension-related diseases, such as hypertension, fibrosis, mitochondrial disease (included within the so-called rare diseases) or Alzheimer's. Research has been published in the journal Proceedings of the National Academy of
Science, Molecular and Cellular Biology and Molecular Cell.

Among other achievements, researchers have identified a biomarker that could serve as early warning of oxidative stress caused by free radicals and hence the risk of developing diseases such as hypertension or fibrosis. Specifically, scientists at the Centro de Investigaciones Biológicas CSIC in Madrid have identified a cellular enzyme, the GAPDH (glyceraldehyde 3-phosphate dehydrogenase), which in normal conditions, interacts with certain structural elements of the messenger RNA, resulting in a low production of endothelin -1, a peptide involved in regulating vascular tone and related diseases such as hypertension or fibrosis.

Researchers at the Consejo Superior de Investigaciones Científicas (CSIC) have identified a new plant models mechanism by which cells regulate the expression of their genes. The finding, with potential applications in genetic engineering, it helps to clarify the evolutionary differences that separate plants from animals. Research results are published in Proceedings of the National Academy of Sciences USA.

Specifically, researchers Maria de la Paz Sanchez, and Crisanto Gutierrez, who worked at the Centro de Biología Molecular Severo Ochoa (CSIC joint center and the Autonomous University of Madrid), have studied the ORC1 protein, which has a crucial role in the initiation of replication of the genome in all eukaryotic organisms (a group that includes plants, animals and fungi, among others). It also serves as a regulator of expression of certain genes.
