Overlapping signals in embryo help get the backbone right

A major step in the development of the vertebrate embryo - the establishment of a back that morphs into a brain, spinal cord and muscles - turns out to be so important that the body uses at least three signals to make sure it happens properly.

Women with non–invasive breast cancer carry the same mutations in two inherited breast/ovarian cancer genes as women diagnosed with invasive breast cancer

The inherited breast/ovarian cancer genes are BRCA1 and BRCA2, which are associated with an increased risk of breast and/or ovarian cancer. The results are part of a five–year study of a common form of early stage breast cancer called ductal carcinoma in situ (DCIS).
