While some uncertainty does exist in climate projections and future health vulnerability, overall increases in heat-related premature mortality are likely by the 2050s, according to a recent study by Columbia University’s Mailman School of Public Health and soon to be published in the November 2007 issue of the American Journal of Public Health.

Pound for pound, carbon nanotubes are stronger and lighter than steel, but unlike other materials, the miniscule cylinders of carbon - which are no wider than a strand of DNA - remain remarkably robust even when chunks of their bodies are blasted away with heat or radiation. A new study by Rice University scientists offers the first explanation: tiny blemishes crawl over the skin of the damaged tubes, sewing up larger holes as they go.

A comprehensive new MIT-led study of the potential for geothermal energy within the United States has found that mining the huge amounts of heat that reside as stored thermal energy in the Earth's hard rock crust could supply a substantial portion of the electricity the United States will need in the future, probably at competitive prices and with minimal environmental impact.
