Sixteen stories below Grand Central Terminal, an army of workers is blasting through bedrock to create a new commuter rail concourse with more floor space than New Orleans' Superdome, just one of three audacious projects going on beneath New York City's streets to expand what's already the nation's biggest mass transit system.

Toni Braxton's autistic son makes his acting debut in her new Lifetime movie, "Twist of Faith," and could have had a bigger role, but the singer didn't want to put too much pressure on him.

LeBron James scored 32 points, and Dwyane Wade added 31 points and eight assists as the Miami Heat held off the Houston Rockets 114-108 on Wednesday.

Presiding over Brazil's first loss to England in 23 years caused Luiz Felipe Scolari little concern. In fact, the returning coach saw Wednesday's 2-1 defeat as a good omen.
