| Real-time observation of the DNA-repair mechanism |
| Thursday, May 22, 2008 - For the first time, researchers at Delft University of Technology have witnessed the spontaneous repair of damage to DNA molecules in real time. They observed this at the level of a single DNA molecule. Insight into this type of repair mechanism is essential as errors in this process can lead to the development of cancerous cells. Researchers from the Kavli Institute of Nanoscience Delft are to publish an article on this in the leading scientific journal Molecular Cell. |

| Experimental agent blocks prostate cancer in animal study |
| Thursday, May 22, 2008 - An experimental drug has blocked the progression of prostate cancer in an animal model with an aggressive form of the disease, new research shows. The agent, OSU-HDAC42, belongs to a new class of drugs called histone deacetylase (HDAC) inhibitors, compounds designed to reactivate genes that normally protect against cancer but are turned off by the cancer process. |

| Metagenomics of skin reveals insights into the human microbiome |
| Thursday, May 22, 2008 - The human body is home to a diverse range of microorganisms, estimated to outnumber human cells in a healthy adult by ten fold. The importance of characterizing human microbiota for understanding health and disease is highlighted by the recent launch of the Human Microbiome Project by the National Institutes of Health. This report, published online today in Genome Research, describes the investigation of healthy human skin for microbiota diversity and establishes the basis for determining a co |
