FDA Completes Review of First Genetically Modified Animal for Consumption
When most people say "genetically modified organism," they usually mean a plant-corn, perhaps, or an eggplant. But that may soon change. The FDA has completed its analysis of the first genetically modified animal likely to hit supermarket shelves: the AquAdvantage salmon, made by Massachusetts-based AquaBounty Technologies, Inc. Thanks to some added genes, the salmon grows 2-6 times the size of a normal Atlantic salmon in half the time, promising some respite for the planet''s heavily taxed natural fish stocks, a third of which are near extinction or exhaustion. Talking Points Memo''s IdeaLab reports that a source close to the review process says that the FDA''s environmental impact statement, which looks at what effect the salmon will have on the environment and seems to be favorable, has been passed on to the White House''s Office of Management and Budget.
Amphibious Network Lets Marines Share Data From 250 Miles Away
The Marines think they have their data network of the future, an experimental communications system that can keep jarheads linked to sea bases 250 miles away. If it works, it''ll be a big win for a Navy/Marine plan to take U.S. troops off of land bases where the locals don''t want them. And it got its first test this week off the Atlantic coast during a massive wargame.
