trials of nitroaspirin by the end of this year. While traditional aspirin has been shown to be effective in clinical trials in preventing certain cancers, it also is associated with significant side effects, including gastrointestinal bleeding, k...
Mice thrive despite massive genetic makeover
...rnal Nature.After completing the sequencing of the human
genome, a question still lingers: is all the non-coding DNA (sometimes called "junk DNA")--which makes up nearly 98 percent of the genome--required, or is some of it potentially disposable? "In these studies, we were looking particularly for seq...

Neurosurgeons identify growth of new adult brain cells, possible treatment for epilepsy
... FRANCISCO It had long been thought that once the human
brain is fully matured, no new brain cells develop. Now a team of researchers and scientists has found evidence of cell generation in the brains of adults with epilepsy and say it could lead to ground-breaking treatment for the disease. William Bin...

New DNA repair enzyme makes mistakes to save lives of cells
.... POL-Q is one of 15 different DNA polymerases in human
cells. These specialized enzymes carry out the duplication, proofreading and repair of DNA. DNA is a double-stranded molecule that contains genes necessary for the production of proteins, which in turn determine all aspects of a cell's structure, fun...
