Got mass? Princeton scientists observe electrons become both heavy and speedy Posted: 13 Jun 2012 02:13 PM PDT A Princeton University-led team of scientists has shown how electrons moving in certain solids can behave as though they are a thousand times more massive than free electrons, yet at the same time act as speedy superconductors. The observation of these seemingly contradictory electron properties is critical to the understanding of how certain materials become superconducting, in which electrons can flow without resistance. Such materials could dramatically increase the efficiency of electrical power networks and speed up computers. read more

Fruit Flies Reveal Mechanism Behind ALS-Like Disease Posted: 13 Jun 2012 01:59 PM PDT Studying how nerve cells send and receive messages, Johns Hopkins scientists have discovered new ways that genetic mutations can disrupt functions in neurons and lead to neurodegenerative disease, including amyotrophic lateral sclerosis (ALS). read more

Researchers Determine Pathway for Origin of Most Common Form of Brain and Spinal Cord Tumor Posted: 13 Jun 2012 01:48 PM PDT Johns Hopkins researchers say they have discovered one of the most important cellular mechanisms driving the growth and progression of meningioma, the most common form of brain and spinal cord tumor. A report on the discovery, published in the journal Molecular Cancer Research, could lead the way to the discovery of better drugs to attack these crippling tumors, the scientists say. read more
