One of the largest icebergs on the planet, about six times the size of Manhattan, has separated from an Antarctic glacier and is floating out towards open ocean. The iceberg is named B-31, and is roughly 255 square miles (660 square km). Its estimated maximum thickness is 1,600 feet (487 meters). Last Fall, it broke off from the Pine Island Glacier. Researchers have been watching it drift away since then, via satellite.
"The ice island, named B31, will likely be swept up soon in the swift currents of the Southern Ocean, though it will be hard to track visually for the next six months as Antarctica heads into winter darkness," according to scientists at NASA's Earth Observatory monitoring its progress.
NASA glaciologist Kelly Brunt said on Wednesday the iceberg covers about 255 square miles (660 square km) and is up to a third of a mile (500 meters) thick. Known as B31, the iceberg separated from Antarctica's Pine Island Glacier last November, Brunt added. "It's one that's large enough that it warrants monitoring," Brunt said in a telephone interview, noting that U.S. government organizations including the National Ice Center keep an eye on dozens of icebergs at any given time.
The iceberg isn't in the way of shipping lanes at this time. One of the funny things about this news story is how each news organization selects a different geographical entity to compare the iceberg's size to. CNN, based in Atlanta, chose Atlanta; AP chose Guam (Really? Guam?), Reuters chose NYC.

Ant Lab's Adrian Smith (previously) writes, "No one had ever filmed how ants inject venom when they sting something. I study ants and I make videos, so I went to work on getting that footage. It involved filming something smaller than a human hair moving faster than the blink of an eye. But, I got […]

Above is a three-millimeter long maggot launching itself into the air for a distance of up to 36 times its body length. Researchers from Duke University and their colleagues studied how these larvae of gall midges leap between plants with the greatest of ease, even rivaling some jumping insects with legs. Their research could have […]
Want to keep the dentist away? A little tooth care at morning and night isn’t bad, but it won’t keep the stains from smoking or fried foods at bay for long. If you enjoy your food and want to avoid the consequences, an upgrade from that old analog toothbrush can make a huge difference. Among […]
If your office works at all, it uses Microsoft Office. Those icons for Word, PowerPoint, and Outlook are as familiar around some workplaces as the coffee machine. So familiar, in fact, that they get taken for granted – and rarely used to their full potential. Whether you need a crash course in the essential tools […]
It’s a great time to be a maker. 3D printers are on store shelves for anyone to buy, and coder kits like Arduino and Raspberry Pi are letting kids as young as 9 or 10 dive into the Internet of Things. Here are a few examples of our favorite tech toys, all priced low enough […]
