Mon, 11 Aug 2008 Heavy Atoms Can Help Destroy Tumor Cells. A new discovery has been made in cancer research. Researchers have now shown that it is possible to improve hadrontherapy"s targeting and destruction of tumor cells by loading the cells with heavy atoms like platinum. This new method enables both the treatment"s effectiveness and the ions" ballistic effect to be improved without damaging healthy tissue.more

Sat, 9 Aug 2008 Large Hadron Collider To Start Up next month. The first attempt to circulate a beam in the Large Hadron Collider (LHC) will be made on 10 September. This news comes as the cool down phase of commissioning CERN"s new particle accelerator reaches a successful conclusion. The LHC is the world"s most powerful particle accelerator, producing beams seven times more energetic than any previous machine, and around 30 times more intense when it reaches design performance, probably by 2010st attempt to circulate a beam in the Large Hadron Collider will be made on Sept. 10.more

Fri, 08 Aug 2008 New Biochemical Pathway That Triggers Critical Repairs In DNA Replication Process Discovered. Scientists have unraveled a new biochemical pathway that triggers a critical repair response to correct errors in the DNA replication process that could otherwise lead to harmful or fatal mutations in cells. Though the work focused on yeast cells, the team expects to find an analogous system in human cells that could be exploited as a target for potential therapies for cancers, which are often caused by such repair mechanisms going off course.more
