Zinc transporters regulate pancreatic cancer

Zinc, an important trace element for healthy growth and development, can be related to pancreatic cancer. Too much ZIP4, a molecule that enables the transport of zinc into cells, promotes the growth and spread of pancreatic tumors cells, said a group of researchers from Baylor College of Medicine in Houston, The University of Texas M.D. Anderson Cancer Center and the University of Florida in Gainesville, in a report which appears online today in the Proceedings of the National Academy of Sciences.

Using neural signals to predict sensory decisions

The rodent whisker sensory system is particularly intriguing because it is "active": the animal generates sensory signals by palpating objects through self-controlled whisker motion (just as we move our fingertips along surfaces to measure their tactile features).

Placenta uses a cloaking device similar to that used by parasites

The placenta uses a cloaking device similar to that used by parasites to avoid detection by the mother's immune system. MRC funded scientists looking to develop a diagnostic test for pre-eclampsia, a major and potentially fatal cause of fetal and maternal illness, made the amazing discovery which could have far reaching implications.
