You are suspended in an endless dark chamber as thousands of red, green, yellow and blue lights flicker across the air like tiny diamonds in the sky.

Immersive exhibits are driving people to museums in search of the perfect snapshot.

The country's first private high-speed rail service is opening this month in Florida, promising to transform congested South Florida highways by taking as many as 3 million cars off the road.

The FBI's failure to unlock the cellphone of the Texas church shooter is reigniting the debate over encryption and government access to secured communications.

Earlier this week, FBI Special Agent Christopher Combs blamed the industry standard encryption for blocking investigators' ability to crack the PIN code on the gunman's device.

Software exists to thwart a passcode, but if forced, investigators run the risk of erasing all of the phone's data. The FBI sent the Texas gunman's phone to its lab in Quantico, Va., to try to determine another method.

More than two weeks after Hurricane Maria made landfall on Puerto Rico, the island's power grid remains in shambles, and authorities say it will take months to fully restore electricity.
