Trying to think green when buying a car? Whether your new fuel-efficient engine helps or hurts the warming planet depends on where you live and what you're putting in the tank.

New cars aim to deliver high performance with maximum fuel efficiency, making them easier on both the environment and the wallet.

Sarcoma is an aggressive form of cancer responsible for up to 20 percent of childhood cancers. Tumors often first appear in the extremities and the abdomen.
