YAHOO.COM - Antarctica is so vast that the pictures give you no sense of scale. The pencil-thin line across the satellite image of Pine Island Glacier (above) is actually more than 18 miles long, 800 feet across in places, and 180 feet deep.

And it's growing. In the next few months, scientists expect the glacier to create an iceberg about 350 square miles in area. It will probably float northward, melting as it goes.

"Pine Island Glacier is losing ice very quickly, about six meters per year," said Michael Studinger of NASA's Goddard Space Flight Center in Maryland, which sent an expedition called Operation IceBridge to Antarctica in October in an old DC-8 jetliner, modified for scientific operations. It spotted the break in the ice. Earth-observing satellites have been watching it since.

"These things happen on a semi-regular basis in both the Arctic and Antarctic, but it's still a fairly large event," said John Sonntag, Instrument Team Lead for Operation IceBridge, in video recorded on the plane. "So we wanted to make sure we captured as much of that process as we could.

"A lot of times when you're in science, you don't get to capture the big stories as they happen, because you're not there at the right place at the right time," he said, "but this time we were."

To scientists, this is more than a vast spectacle. Both polar caps are losing ice, and researchers studying the world's climate say they want to understand the process.

    SPOKANE, Wash. - A Spokane security guard never thought he'd have to use a tourniquet, but he still carries it with him just about everywhere he goes. "You never know when you're going to come across something where you could be the guy to help because you know what to do," said John Roach. " I wanted to help the guy and I was able to." Roach was driving on Market Street in north Spokane when he came across the aftermath of a hit-and-run.

    WASHINGTON - Trains that carry oil and other flammable materials near communities won't have to install electronically controlled braking systems to reduce risk of derailments and explosions after the Trump administration reversed an Obama-era safety rule on Monday. In a post on its website, the Pipeline and Hazardous Materials Safety Administration argued that the cost of installing the new brakes outweighs the benefit.
