Declining water levels exposed much of the Great Salt Lake's bed and created conditions for storms of dust laden with toxic metals that now threaten 2 million people.

Offshore wind is well established in the U.K. and some other countries but is just beginning to ramp up off America’s coasts.

Known as the Square Kilometre Array, the mega observatory consists of huge clusters of dishes and antennas spread across remote parts of South Africa and Western Australia.

As of Thursday afternoon, the lava was about 3.2 miles away from the Daniel K. Inouye Highway, also known as Saddle Road, which connects the east and west sides of the Big Island.

"You could be the smartest doctor in the world, yet you're useless if your patients don't understand what you are saying," a University of Minnesota researcher said.

The video, captured by helicopter, shows the volcano spewing fountains of lava, which stretch across its surface, as clouds of smoke rise above.

Some black holes unleash incredibly bright jets of high-energy particles. Researchers say they're starting to understand why.

It is the volcano's first eruption since 1984, the U.S. Geological Survey said. Officials said lava flows were "contained within the summit area and are not threatening downslope communities."

The station’s third and final module docked with the station this month, one of the last steps in China’s more than decadelong effort to maintain a constant crewed presence in orbit.

The measures taking effect Friday will include reductions on water for the irrigation of crops and industry.

Pollution is triggering algae blooms that have killed much of the seagrass on which manatees depend, conservations groups said.
