Blue Crab Nanosensor to Fight Terrorism

Roland Piquepaille writes "A substance found in crab shells called chitosan has very useful properties. For example, it has been used in bandages to stop bleeding. But now, researchers at the University of Maryland have used the chitosan from blue crabs living in Chesapeake Bay as a component of a nanoscale sensor system which could save many lives in the future. These blue crab nanosensors will be used to improve security in airports, hospitals and other public locations by detecting tiny amounts of explosives or chemicals in air and water. Read on for additional references and pictures of these blue crab nanosensors."

Nothing fights terrorism like Justice

Of course it's been said before, but investing in all these whiz-bang anti-terrorism devices is missing the point. You can't fight a social phenomenon such as terrorism with technology. You have to address its root cause(s). Right now, the root cause of terrorism is overwhelmingly the massive injustices thrust upon the people of the Middle East in the name of grabbing their oil. It would be a lot cheaper for the US to forget this bullshit 'war on terrorism' and relocate all the Israelis to Washington. After all, the US is Israel's closest ally. Why shouldn't such friends live so close together.
