Where Bacteria Get Their Genes

...nd dumping it into another. Bacteria can also make contact by tiny connection tubes through which they exchange pieces of DNA. They can also take up genetic material from the environment. Ochman thinks the team's findings will stir new research in bacterial evolution. "It should be exciting to see whether g...

Study shows how retinoic acid enters a cell's nucleus

... the CRABP-II protein before and after it comes in contact with RA, Noy and Sessler made a startling discovery: When exposed to RA, three amino acids on the CRABP-II molecule flip their positions, exposing positive charges. Combined with the way the molecule is folded, this area suddenly looks like a classic...
