Genetically engineered bacteria paint microscopic masterpieces

IMG_8586

Scientists have used genetically engineered bacteria to recreate a masterpiece at a microscopic scale. By engineering E. coli bacteria to respond to light, they’ve guided the bacteria like tiny drones toward patterns that depict Leonardo da Vinci’s Mona Lisa. It’s not artistic recognition they’re after. Rather, the researchers want to show that these engineered organisms may someday be used as “microbricks” and living propellors.

Worm Regenerates Entire Body from a Single Cell

Asexual fission from one cell?

Planarians, a type of flatworm, reproduce by asexual fission. Cut one in half, and the missing parts will regrow until you have two planarians. Scientists have known for a while that the regeneration took place among a cluster of cells called cNeoblasts. Some wondered if was possible to grow an entire worm from a single such cell, and so performed an experiment…
