Why female moths are big and beautiful
In most animal species, males and females show obvious differences in body size. But how can this be, given that both sexes share the same genes governing their growth? University of Arizona entomologists studied this conundrum in moths and found clues that had been overlooked by previous efforts to explain this mystery of nature.Fruit Flies — A Model for Bodybuilders
(PhysOrg.com) -- The human body operates by a precisely regulated interplay of different cell types such as blood, nerve and muscle cells. Together with colleagues from the Research Institute of Molecular Pathology (IMP) in Vienna, Austria, scientists of the Max Planck Institute (MPI) of Biochemistry in Martinsried near Munich, Germany, have now succeeded in identifying all genes of the fruit fly Drosophila that play a role in the development and function of muscles. "It is fascinating how the genetic programme of an organism is able to produce such different cell types out of identical precursor cells," says Frank Schnorrer, group leader at the MPI of Biochemistry.

Cybertron isn't just the homeworld of the Transformers... it is a Transformer itself. It was the first Transformer. In War for Cybertron you get to explore the Civil War between the Autobots and the Decepticons as they blast their way across the planet. At GDC we were treated to a long demo of the game, and yes, it looks good.
The characters were given all-new designs, and some of them will in fact be made into toys. The game takes place before Optimus gains his "Prime" designation, and shows his early days of gaining the trust of the Autobots; we get to see just how he learned to be a leader on the battleground. On the flip side of things, the game explores how Megatron met Star Scream. "We also explore why Megatron keeps this guy, who is basically a back-stabber, around," we were told. This game is taking the Transformers lore back to basics, and filling in some serious holes.
