Editing of Pig DNA May Lead to More Organs for People
In a typical experiment, scientists use Crispr to alter a single gene. But in recent work with pig cells, Dr. Church and his colleagues used Crispr to alter 62 genes at once. The researchers hope that this achievement may someday make it possible to use pig organs for transplantation into humans.

Still More Evidence That Antioxidant Supplements Actually Increase Cancer Risk
As described in the current issue of Science Translational Medicine, researchers have found that antioxidants as much as double the rate of melanoma metastasis in mouse models. The results align well with other recent research by the same groupfinding that antioxidant supplements hasten and aggravate the progression of lung cancer, the most common form of…
