euronews hi-tech – Radiation-surviving organism yields its secrets
The “world’s toughest bacterium” seems to have superpowers that can survive even the deadly gamma radiation that comes from a nuclear explosion. An international group of scientists has published the results of a long study of a soil microorganism that can stand about a thousand times more Gamma rays than a human. Hi-tech spoke to Macromolecular Crystallographer Joanna Timmins: “One of the main focuses of the work in our group is the study of this bacteria called Deinoccocus radiodurans, which is extremely radiation resistant, and so we’re trying to understand a little bit more how it has developed such properties, since nowhere on Earth are there such high doses of radiation that it can actually withstand.” Was the radioresistant bacterium brought to Earth from Mars, as one theory suggests, or were its mechanisms developed on Earth as a side effect of drought or other distress? Its defense works on the molecular level. To see how this incredible jump between the worlds of physics and natural science works a traditional microscope will not do. Scientists use the European synchrotron, located in Grenoble, France, to discover the atomic structure of the bacterium’s protein defense system. Synchrotrons produce thin beams of X-ray light using the energy emitted by electrons accelerated in a vacuum inside a circular magnetic field. The powerful X-ray beams are then “tailored” so their wavelengths can have the desired experimental characteristics, and the molecule hunt can …

the point of tech its that we never suffer again, make our life easier, so maybe in 200 years, earthquakes will do no harm, to our society, we, as humans, might have limits, but day after day we’re breaking those limits, till one day we may even be inmortals beings
Fantastic!
Hi-tech!!… Yes in deed!!…But after the Disaster ( earthquake ,tsunami,radio active explosion ) where Is Japan now? .. . . no matter how You invent Hi=tech., people should know its Limits. .. sometimes return to innocence may work> after all ..Where are those Hi-techs now? … enough is enough.

Dear YouTube,
The Like/Dislike system, I can live with. I’ve gotten used to it now.
The new comment layout, fine with me.
But THIS, is just too much too take! The front page has completely lost it’s organised, simple layout!
I don’t know where you get your ideas, but I think I speak for a big part of the community when I say “YouTube, go F*ck yourself.” Give this a thumbs up and copy/paste it around
Awesome!
