Physicists in Germany have developed a novel technique for trapping biological cells with a laser beam. Using this technique, the researchers obtained super-resolution images of chromosomal DNA within E. coli cells. Picture of the distribution of the genetic information in an E. coli cell.

Biology is messy, and this is a problem for imaging science. Living things are squishy and porous. They tend to be bathed in fluid. They also move, and all that motion makes it practically impossible to get good high-resolution images of cells and what’s inside them. The best we’ve had to …
