The bacterium Micavibrio aeruginosavorus (yellow), leeching
on a Pseudomonas aeruginosa bacterium (purple).
What’s the news: If bacteria had blood, the predatory microbe Micavibrio aeruginosavorus would essentially be a vampire: it subsists by hunting down other bugs, attaching to them, and sucking their life out. For the first time, researchers have sequenced the genome of this strange microorganism, which was first identified decades ago in sewage water. The sequence will help better understand the unique bacterium, which has potential to be used as a “living antibiotic” due to its ability to attack drug-resistant biofilms and its apparent fondness for dining on pathogens.
Insight into long life is one of the new prize’s goals.
In 2006, the Genomics X Prize competition was announced: $10 million for sequencing 100 human genomes in 10 days for $10,000 apiece, to be kicked off in 2013. The idea was to spur innovation in technology by asking the (currently) impossible, the hallmark of the X Prize Foundation.
But while sequencing has gotten cheap, it hasn’t gotten all that much faster in the last five years, and none of the eight teams who signed up have ever gotten to the point where such a short time span could be feasible. So, Archon and Medco, the two companies funding the competition, have revamped the requirements. This week they’ve announced the new, improved Genomics X prize: $10 million for sequencing 100 human genomes in 30 days—but for $1,000 apiece. (Currently, getting your genome sequenced commercially runs about $5000 at the cheapest.) The new version of the competition, which will kick off on January 3, 2013, also has clearer standards for judging: the genomes have to be 98 percent complete and have no more than one error per million nucleotides.
What’s the News: Scientists have been rooting around in the rice genome for years, and the same goes for wheat. But now the long-recalcitrant potato genome has finally been sequenced. Time for a celebration? Perhaps, but biologists can’t rest for long: in addition to the just-published genome, there are still three more to sequence in each commercial potato.
