Gamers succeed where scientists fail


Gamers have solved the structure of a retrovirus enzyme whose configuration had stumped scientists for more than a decade. The gamers achieved their discovery by playing Foldit, an online game that allows players to collaborate and compete in predicting the structure of protein molecules.
After scientists repeatedly failed to piece together the structure of a protein-cutting enzyme from an AIDS-like virus, they called in the Foldit players. The scientists challenged the gamers to produce an accurate model of the enzyme. They did it in only three weeks.

Scientists using a widely distributed game as a think tank for solving real life problems? Stargate Universe called it.

Interestingly, if you too would like to fold proteins for science, foldit beta is available here. Going to check it out myself when I have a chance. While I doubt it'll be the next Call of Duty installment, I'm glad someone is actually putting this idea into practice. Now if they'd only take it that one final step and capitalize on the most detail oriented and obsessive gamers there are, MMO players...

What does it feel like to fly over planet Earth?

"A time-lapse taken from the front of the International Space Station as it orbits our planet at night. This movie begins over the Pacific Ocean and continues over North and South America before entering daylight near Antarctica. Visible cities, countries and landmarks include (in order) Vancouver Island, Victoria, Vancouver, Seattle, Portland, San Fransisco, Los Angeles. Phoenix. Multiple cities in Texas, New Mexico and Mexico. Mexico City, the Gulf of Mexico, the Yucatan Peninsula, Lightning in the Pacific Ocean, Guatemala, Panama, Columbia, Ecuador, Peru, Chile, and the Amazon. Also visible is the earths ionosphere (thin yellow line) and the stars of our galaxy."

Life-like cells are made of metal - life - 14 September 2011 - New Scientist

Life-like cells are made of metal - life - 14 September 2011 - New Scientist


Could living things that evolved from metals be clunking about somewhere in the universe? Perhaps. In a lab in Glasgow, UK, one man is intent on proving that metal-based life is possible.

He has managed to build cell-like bubbles from giant metal-containing molecules and has given them some life-like properties. He now hopes to induce them to evolve into fully inorganic self-replicating entities.

Ok, really? Does no one else on the planet read science fiction? Grey goo scenario anyone?

Colonel Jack O'Neil wouldn't be pleased.
