Octopuses rewrite their RNA to function in frigid Antarctic waters

We all know octopuses are clever, but a recent study reveals that the brainy beasts are crafty even at the molecular level. In a study published in the latest issue of Science, researchers reveal that octopuses living in the hypothermic climes of Antarctica rely not on their DNA, but the revision of their RNA, to… » 1/06/12 10:40am 1/06/12 10:40am

This alien-looking fish just rewrote the book on developmental genetics

If you were to suggest that members of Elasmobranchii — the subclass of cartilaginous fishes that includes sharks, rays, and skates — look incredibly different from us humans, I doubt that many people would argue the point. In fact, one look at the alien-like skeleton of Leucoraja erinacea, the species of skate… » 12/15/11 12:13pm 12/15/11 12:13pm

Scientists unlock the genetic basis for weed's high

Not all weed is created equal. Some members of the Cannabis genus pump out tetrahydrocannabinol (aka THC, the plant's main psychoactive chemical) like nobody's business, while others produce very little of the mind-altering molecule. But the genetic basis for why some plants excel at getting you high while others are… » 10/20/11 4:20pm 10/20/11 4:20pm
