NatureNew dinosaur raptor found; First in Southern Hemisphere
Scientists at Ohio State University and the Argentine Museum of Natural History have identified a new species of raptor dinosaur from fossils found in Patagonia -- the very southern tip of South America. It is the first raptor ever found in the Southern Hemisphere, but compared to other raptors, Neuquenraptor argentinus wasn't much of a standout.

Growth in the sea comes down to a struggle for iron
Injecting iron into some major regions of the oceans can stimulate the growth of diatoms and other phytoplankton, but something odd occurs as these tiny marine plants continue to grow. They begin to starve in the midst of plenty, acting as though iron is in short supply. It could be that iron sets off a kind of chemical warfare in the marine ecosystem.

Proceedings of the National Academy of SciencesTermites feed through good vibrations
CSIRO entomologist Theo Evans says laboratory experiments have found that termites use their ability to detect vibrations to determine which food source is most suitable. The termites can also detect how the vibrations are made. This ability could be likened to a form of sonar.

NatureScientists discover why the North Pole is frozen
Ice has been building up in the Arctic for 2.7 million years. Until now, no-one has been able to prove what mechanism brought about this accumulation of ice. However, a team of international scientists led by Antoni Rosell, a researcher for the Universitat Autònoma de Barcelona, and Gerald H. Haug of the Potsdam Institute for Climate Impact Research (Germany) has discovered the mechanism that set off the accumulation of ice.

Polar expedition contributes to ESA's ice mission CryoSat
In a few days, a three-man scientific expedition called Pole Track is to embark upon a gruelling 1000 km trek across the frozen Arctic to collect valuable data for climate-change research. Throughout the demanding two-month expedition, the team will also take thousands of snow depth measurements in support of ESA's CryoSat mission.
