Ancient eggshell protein breaks through DNA time barrier
Scientists have identified fossil proteins in a 3.8 million year-old ostrich eggshell, suggesting that proteins could provide valuable new insights into the evolutionary tree, much further back in time than was previously thought.

Eat, escape, love: The price of looking sexy
In the animal kingdom colorful traits can be both a blessing and a curse. A new study has studied the conspicuous wing coloration of two species of damselflies. Their results imply that males, but not females, pay a high cost when using color to communicate with other damselflies, both in terms of predation risk and visibility to prey.

Regulatory RNA essential to DNA damage response
It iss essential for cells to quickly ascertain whether it's possible to repair mistakes or to self-destruct for the good of the organism. That's because cells with a damaged genome often begin to flout the standard rules of growth and become cancerous. Now, researchers have discovered a new player in this high-stakes molecular game in the form of a novel regulatory RNA they've named DINO. This RNA molecule binds to and stabilizes a well-known tumor suppressor protein called p53 that mobilizes a cell's response to DNA damage. When mutated, p53 is one of the most infamous bad guys in the cancer world.
