Shielding The Brain From Too Much Insulin Can Prolong Life

Almost a year in the making, a federal plan to prioritize research on the potential environmental, health, and safety impacts of nanoscale materials has so many failings that its begs the question as to whether the government's 13-agency nanotechnology research effort is able to deliver an effective risk research strategy, according to David Rejeski, head of the Wilson Center's Project on Emerging Nanotechnologies. Study Finds Many Patients Don't Understand Prescription Medicine Label
Many people don't fully understand the seemingly simple label instructions on their prescription medication, according to a Northwestern University study of low-income patients.

Mapmaking For The Masses: User-generated Content Can Profoundly Impact
Sites such as Wikimapia and OpenStreetMap are empowering citizens to create a global patchwork of geographic information. According to Michael Goodchild from the University of California in Santa Barbara, 'volunteered geographic information'has the potential to be a significant source of geographers'understanding of the surface of the Earth.
