Scientists: Mussels may leave carp nothing to eat

food fight

Mussels may outmuscle asian carp

If huge, hungry Asian carp reach Lake Michigan, their long-dreaded and costly invasion may turn out to be less ferocious than once expected because a tiny competitor is gobbling up their primary food source, some Great Lakes researchers say. The quagga mussel, a thumbnail-sized foreign mollusk first spotted in the lakes two decades ago, has devoured so much plankton in southern Lake Michigan that the entire food web is being altered, federal and university scientists reported in a series of newly published articles. Mussels have "beaten the Asian carp to the buffet table," Gary Fahnenstiel, senior ecologist with NOAA's Great Lakes Environmental Research Laboratory, said. "While the public has been worried about Asian carp and the Chicago canal, another invader has fundamentally changed the lake and made it inhospitable to the Asian carp."

iran is crafty

It's a boat, a plane, no, it's a weapon

Iran's powerful Revolutionary Guard received its first three squadrons of radar-evading flying boats. The domestically made craft can be used for surveillance and can carry guns and transmit data. Iran announced last year it had successfully tested the plane, dubbed the Bavar-2, or Confidence-2. A flying boat is a seaplane with a hull that allows it to land and travel on water.

Minks are on the lam in Ireland

The roads and rivers of northwest Ireland are suddenly lined with mink. Managers at Anderson's Mink Farm said Wednesday that many of their cages and fences were cut and opened over the weekend, freeing an estimated 5,000 animals into the wilds of County Donegal. About 28,000 others declined the invitation to bolt for freedom. More than 100 have been recaptured by hunters using cage traps, while several hundred others have been run over and killed. Drivers reported seeing groups of the farm-reared animals standing, dazzled by headlights, in the middle of busy roads.

Russian hotel will have lots of space

A Russian company announced an ambitious bid to fill the vacuum in the space tourism market by stationing an orbiting hotel in the cosmos. The Moscow-based Orbital Technologies has sky-high hopes that its planned Commercial Space Station can serve as a tourism hub for well-heeled travelers and offer overspill accommodation for the International Space Station and workspace for science projects. The company wants to launch a seven-room station by 2016 but may increase or decrease capacity based on customer demand.
