Only half of eligible women in the United States are getting their annual mammograms, even if they have insurance to pay for the procedure, according to data presented at the 33rd Annual CTRC-AACR San Antonio Breast Cancer Symposium.

A myriad of inputs can indicate a body's health bombard pancreatic beta cells continuously, and these cells must consider all signals and "decide" when and how much insulin to release to maintain balance in blood sugar, for example. Reporting in Nature Chemical Biology last month, researchers at the Johns Hopkins University School of Medicine have teased out how these cells interpret incoming signals and find that three proteins relay signals similar to an electrical circuit.

Scientists have sequenced the genome of a major fungal disease that affects barley and other cereal crops, a breakthrough that could lead to significant advances in our understanding of how plant diseases evolve. The research, published today in the journal Science, suggests that parasites within the genome of the fungus help the disease to adapt and overcome the plant's defences.

Johns Hopkins scientists have identified a previously unrecognized step in the activation of infection-fighting white blood cells, the main immunity troops in the body's war on bacteria, viruses and foreign proteins.
