Study extends scientific understanding of how pheromones activate the vomeronasal organ

The vomeronasal organ (VNO) is one of evolution's most direct enforcers. From its niche within the nose in most land-based vertebrates, it detects pheromones and triggers corresponding basic-instinct behaviors, from compulsive mating to male-on-male death matches. A new study from the Stowers Institute for Medical Research, published online in Nature Neuroscience on July 29, 2012, extends the scientific understanding of how pheromones activate the VNO, and has implications for sensory transduction experiments in other fields.

New paper discusses potential of tumor-derived microvesicles

A new paper by Crislyn D'Souza-Schorey, professor of biological sciences at the University of Notre Dame, discusses the biology of tumor-derived microvesicles and their clinical application as circulating biomarkers. Microvesicles are membrane-bound sacs released by tumor cells and can be detected in the body fluids of cancer patients.

Study shows important aspects of how sodium and potassium are regulated in the kidney

High blood pressure (hypertension) is a principal risk factor for heart disease and affects 1 billion people. At least half of them are estimated to be salt-sensitive; their blood pressure rises with sodium intake. New research shows important aspects of how sodium and potassium are regulated in the kidney.
