    try{document.getElementById("aol-cms-player-1").style.display="none";}catch(e){}Today on In Case You Missed It: Researchers at the Oak Ridge National Laboratory created ethanol out of carbon dioxide in a way that they believe would be easy to scale up. Most importantly, the conversion happens at room temperature so it could be done nearly anywhere in the world. We are also tickled by this stop-motion music video for a new song by Dan Sultan, and enjoy the dress designer who wants to put alcohol in clothes. As always, please share any interesting tech or science videos you find by using the #ICYMI hashtag on Twitter for @mskerryd.

  • Cray Jaguar leaps past IBM Roadrunner as world's fastest supercomputer and pun generator (video)

    Cray has finally clawed IBM back from the lead position on the Top500 Supercomputer chip-measuring contest. After just missing out on the title to IBM's Roadrunner last year, Cray's XT5 supercomputer (aka, Jaguar) at Oak Ridge National Lab in Tennessee received an update from quad- to six-core Opteron processors to boast a 2.3 petaflop per second performance peak (theoretical) and 1.75 petaflops as measured by the Linpack benchmark; a feat requiring almost a quarter million AMD cores. IBM's Roadrunner, the very first supercomputer to race past the petaflop per second threshold, managed just 1.042 petaflops by comparison. Remember, one petaflop per second is equivalent to one quadrillion calculations per second. Of course, chip makers put their own spins on the list by noting that 4 of the top 5 systems depend on AMD for performance while Intel can be found powering 402 of the Top500. Video of the AMD processor upgrade procedure can be found after the break.
