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."

    Oh, good, we've got nanosensors. Now we can stop overreacting maniacally to attacks, the wildfire of uncontrolled fear that destroys our freedom more than any bomb ever could. I can't wait to see our leaders appear on TV to tell us we can calm down.

      While I do agree that we, as a nation, have overreacted quite a bit to terrorist actions, that doesn't mean we shouldn't work on security precautions. Prevention and mitigation are two of our strongest weapons that can help people avoid the need to worry.

      On the other hand, I'm not all that convinced that these new security measures are really doing that much to make things like air travel safer. I know someone who accidentally took firecrackers in his pocket on an flight across the US once (after 9/11). The security people x-rayed and felt through all of his on-person possessions, but so much junk had accumulated in his pockets that they did not notice the presence of explosives.

      "Cars kill more people than bombs do but a sensor to detect bombs is a good thing but speed cameras are evil. Guess which potentially saves more lives?"

      Ever wonder why they call it terrorism instead of mass-murder? 9-11 did a lot more damage than car crashes. The gubment's handling of terrorism is questionable, but the prioritization of it over car crashes is not nearly as black and white. Anti-terrorism (The intent, I mean, not 'The War Against Terror'...) is about more than just the saving of lives. Think about what the first week after 9-11 was like, then think about the year that followed. The fear, paranoia, and hardships that followed were incalcuable. There's a reason it's not swept under the rug until car crashes are dealt with. Think about it.

      On the other hand, maybe this is the only way to get the government interested in saving the Chesepeake Bay ecosystem. :-)

      And whose fault was the paranoia?

      Look, I travelled every day to go to class on one of the lines where a train blew up in Madrid, only fortunately in the afternoon instead of the morning. I had a friend personally present there, and a classmate of mine died there.

      But you know what I did next day? I went to class just like everybody else. I certainly wasn't demanding useless measures to be taken to protect me against something against which no protection is possible, and neither was most of the country.

      As a matter of fact, to go to work I have to cross a dangerous road where sometimes the traffic lights *aren't working*. I'm much more likely to be killed by a truck on that road than by a bomb. There you have one place where spending some money would be actually useful.

    A funny example is an industrial town I fly to on a regular basis. Most of the people work in the mines, where explosives can be a common part of many poeples jobs. When explosives traces are regularly detected at the airport explosives scan, their first question is "Have you been on a mine site recently?" Obviously 99% of people say yes, and are let through without question.

  15. TSA is a mindset we don't want by ianscot · · Score: 4, Informative

    I used to take my dog -- a Newfoundland -- in to the airport to pick people up. The baggage claim at our local airport basically lets people get dogs off their leashes after a flight, and according to the local cops it was okay. Never had a cross word from anyone; I wasn't inflicting too many more allergens on anyone, I hoped, and mostly we got a lot of good socialization when she was a puppy. At least some people seemed to get a wake-up in the middle of their exhausting travel day.

    One day a TSA employee caught sight of us. A squad of four of them surrounded me, quietly preventing me from moving away as one lectured me on all the potential dreadful consequences should they decide to enforce their vaguely-defined regulations. I tried to ask after the specific laws or airport restrictions involved. There probably were some -- I'd always assumed the cops were just being smart about what to enforce and what not to -- but it was clear that the TSA guys were entirely motivated by that obnoxious self-righteousness I recognize from birding near power plants. You know, the one that comes with private security agencies taking themselves too seriously and not having clear "boundaries," so that they end up thinking their job is to harass people. Said people are to be presumed guilty, of course.

    End result was me feeling intimidated, which seemed to be the goal. Those guys were a hybrid between hallway monitors and the bullies from your middle school.

    Somehow the local cops had always managed to keep me in line, and to prevent potential terrorist attacks by Newfoundland drool and shedding, without any ill will. If one of them had brought this up with me I'd have taken it a lot differently...
