Scientists have only recently begun to speculate that what's referred to as "junk" DNA – the 96 percent of the human genome that doesn't encode for proteins and previously seemed to have no useful purpose – is present in the genome for an important reason. But it wasn't clear what the reason was. Now, researchers at the University of California, San Diego (UCSD) School of Medicine have discovered one important function of so-called junk DNA.

In the daunting marathon that leads to successful drugs, promising drug candidates must pass toxicity tests before entering clinical trials. Researchers from MIT and the Whitehead Institute have developed a cell culture test for assessing a compound's genetic toxicity that may prove dramatically cheaper than existing animal tests. This assay would allow genetic toxicity to be examined far earlier in the drug development process, making it much more efficient.
