Summary

Last week, GenBank posted the genetic sequence of GFAJ-1, a bacterium that appeared to incorporate arsenic in its DNA. Belgian researchers are building DogCam, a dual-camera system that can follow a dog's gaze. A radiologist has teamed with two violinmakers to build neo-Stradivarius violins based on computed tomography data fed into a computer-controlled wood mill. And this week's numbers quantify U.K. spending on research infrastructure and global carbon emissions in 2010.
