Microscopic creatures called epibionts that live on sea turtles’ shells can help researchers understand their secretive lives.
Bacteria and Humans Have Been Swapping DNA for Millennia
Kelly Robinson and Julie Dunning Hotopp | Oct 1, 2016 | 8 min read
Bacteria inhabit most tissues in the human body, and genes from some of these microbes have made their way to the human genome. Could this genetic transfer contribute to diseases such as cancer?

Researchers find evidence of antibiotic resistance genes in the DNA of viruses that infect bacteria.
Researchers in George Church&rsquo;s lab modified wild type ADK proteins (left) in <em >E.coli</em>, furnishing them with an nonstandard amino acid (nsAA) meant to biocontain the resulting bacterial strain.

Photo: Ori Fragman, Hebrew University Hordeum spontaneum, the plant studied for BARE-1 retroelements. With genome sequences arriving almost as regularly as the morning paper, the public's attention is focused on genes--new genes to protect crops against pests; rogue genes that make bacteria resistant to antibiotics; faulty genes that, if fixed, could cure diseases such as muscular dystrophy. What many people don't realize is that genes account for only part of an organism's DNA, and in many c
