Octopuses occasionally stroll around on two arms, UC Berkeley biologists report

Ordinarily, "you wouldn't look at that gene and say it's an obvious candidate for dramatically changing skeletal structures in wild animals that end up completely viable and healthy,' he said.

Ants Genetic Engineering Leads To Species Interdependency

...labor, agriculture, and even slavery.Indeed, these traits have been taken to their extreme in many antspecies, such as the case of slavemaker ants, which have become sospecialized for raiding food from the colonies of other ants that theycan no longer feed themselves or raise their younger siblings.Recent w...

Research on Worms Yields Clues on Aging

...ty. Treated wormscontinued to display the youthful traits of fast body movement and fastpumping of mouthparts during the latter phase of their extended lives.Further tests showed that the anticonvulsants stimulated transmissionof signals in nerves that control body movement.Scientists previously had found g...

Genome of deadly amoeba shows surprising complexity, evidence of lateral gene transfer

...ges ?because the amoeba lacked many of the visible traits of eukaryotic cells (such as endoplasmic reticulum, golgi apparatus and mitochondria) and also shared some bacteria-like traits. While the Nature study catalogs a reduced genome (sometimes characteristic of an organism's transition to a parasitic li...
