Wood Ant Queen Has No Egg-laying Monopoly:
The reproductive monopoly of the ant queen is not as strong as is often thought. Dr. Heikki Helanterä and Prof. Lotta Sundström, biologists working at the University of Helsinki, Finland, investigated worker ovary development and egg laying in nine Northern European wood ant species of the genus Formica, and revealed wide spread reproductive endeavours by workers.
City Site Was Dinosaur Dining Room:
A dinosaur bone bed in southwest Edmonton that served as a feeding area for the direct ancestor of Tyrannosaurus rex has revealed that two dinosaurs, thought to have lived in different eras, actually lived at the same time. Scientists digging for bones at the site this year discovered fossils of Edmontosaurus and Saurolophus this year.
Translating Form Into Function:
In the last 40 years, scientists have perfected ways to determine the knot-like structure of enzymes, but they've been stumped trying to translate the structure into an understanding of function -- what the enzyme actually does in the body. This puzzle has hindered drug discovery, since many of the most successful drugs work by blocking enzyme action. Now, in an expedited article in Nature, researchers show that a solution to the puzzle is finally in sight.
