Oceangoing sailing rafts plied the waters of the equatorial Pacific long before Europeans arrived in the Americas, and carried tradegoods for thousands of miles all the way from modern-day Chile to western Mexico, according to new findings by MIT researchers in the Department of Materials Science and Engineering.

A growing number of plug-in hybrid electric cars and trucks could require major new power generation resources or none at all— depending on when people recharge their automobiles.

Rather than improving motorist safety, red-light cameras significantly increase crashes and are a ticket to higher auto insurance premiums, researchers at the University of South Florida College of Public Health conclude.

Researchers at the Georgia Institute of Technology have developed a strategy to capture, store and eventually recycle carbon from vehicles to prevent the pollutant from finding its way from a car tailpipe into the atmosphere. Georgia Tech researchers envision a zero emission car, and a transportation system completely free of fossil fuels.
