How yeast chromosomes avoid the bad breaks
The human genome is peppered with repeated DNA elements that can vary from a few to thousands of consecutive copies of the same sequence. During meiosis—the cell division that produces sperm and eggs—repetitive ...

Shock tactics: Bioelectrical therapy for cancer and birth defects?
Stem cell therapies hold increasing promise as a cure for multiple diseases. But the massive potential of a healthy stem cell has a flip side, as faulty regulation of stem cells leads to a huge range of human diseases. Even ...

Use the common cold virus to target and disrupt cancer cells?
A novel mechanism used by adenovirus to sidestep the cell's suicide program, could go a long way to explain how tumor suppressor genes are silenced in tumor cells and pave the way for a new type of targeted ...

New role for the JNK protein
Put simply, a tumor is the result of out-of-control cell growth. To assure that the cell cycle - the cell's process of duplicating itself to make more cells - goes smoothly, a large network of proteins tells other proteins ...

Study finds why some women are sub-fertile with a poor response to ovarian stimulating hormones
Researchers have discovered that some women carry a genetic variation that makes them sub-fertile and less likely to respond to ovarian stimulating hormones during fertility treatment. The discovery opens the way to identifying ...
