Synthetic biology researchers at MIT are creating simple analog computers in living cells, complete with fluorescent “displays.” Rahul Sarpeshkar and Timothy K. Lu engineered genetic circuits in E. coli so that the bacteria glows with a brightness determined by the amount of certain chemicals surrounding it. From Science News: By making bacteria glow more or less brightly depending on the number of different chemicals around, the new circuit can compute answers to math problems, Lu’s team reports May 15 in Nature. To add 1 plus 1, for example, the circuit would detect two chemicals and crank up the bacteria’s glow to “2.” ” Analog circuits boost power in living computers ” (Science News) ” Cell-Based Computing Goes Analog ” (The Scientist) ” Synthetic analog computation in living cells ” (Nature)

After taking a few shadowy pictures for the scientific world’s paparazzi, the atom is now ready for its closeup. Today, a team of IBM scientists are bypassing the big screen to unveil what they call the “world’s smallest movie.” This atomic motion picture was created with the help of a two-ton IBM-made microscope that operates at a bone-chilling negative 268 degrees Celsius. This hardware was used to control a probe that pulled and arranged atoms for stop-motion shots used in the 242-frame film. A playful spin on microcomputing, the short was made by the same team of IBM eggheads who recently developed the world’s smallest magnetic bit . Now that the atom’s gone Hollywood, what’s next, a molecular entourage? Filed under: Storage , Science , Alt Comments
Haiti has been battling a massive cholera outbreak since, roughly, around the time international aid groups arrived in the country following the 2010 earthquake. Now, genetic evidence links the strain of cholera in Haiti to a rare strain native to Nepal — further proof that it was Nepalese UN Peacekeepers who brought cholera to Haiti . This news comes two months after the UN claimed immunity from any financial liability relating to the outbreak, writes Stacey Singer at the Palm Beach Post.
A lot of the stuff about the movie Hackers looks really dated now, especially some of the fashions and the way it depicts hacking. But the user interface still looks pretty good, compared to a lot of other stuff from the era. Paul Franklin, the Academy Award-winning special effects designer who’s worked on all Christopher Nolan’s recent movies, also worked on Hackers and holds it up as an example of a weird choice that panned out: More »
