The media slant political news to the left or right to increase ratings and profits, spinning up an information vacuum that can lead to mistakes at the ballot box, a new study by three University of Illinois economists says.
Evidence Of Massive Asteroid Impact On Mars Supported By Computer Simulations

The dramatic differences between the northern and southern hemispheres of Mars have puzzled scientists for 30 years. One of the proposed explanations -- a massive asteroid impact -- now has strong support from computer simulations carried out by two groups of researchers.
Food Scientists Confirm Commercial Product Effectively Kills Bacteria In Vegetable Washwater

Research conducted by food science faculty at the University of Idaho and Washington State University indicate that a commercially available fruit and vegetable wash, when used in a food-manufacturing setting, can dramatically decrease the number of disease-causing organisms in produce-processing washwater. That could reduce by manyfold the potential for cross-contamination within the water by such "gram-negative" bacteria as Salmonella and E. coli O157:H7.
Census Of Marine Life Lists 122,500 Known Species, Over Halfway To Complete Inventory By Oct. 2010

Census of Marine Life-affiliated scientists consolidating world databases of ocean organisms have demoted to alias status almost one-third of all names culled so far from 34 regional and highly specialized inventories. Experts will complete the World Register of Marine Species by October 2010 as part of the first Census of Marine Life.
Estimation Of Isolation Times In The Drosophila Simulans Complex

The Drosophila simulans species complex continues to serve as an important model system for the study of new species formation. The complex is comprised of the cosmopolitan species, D. simulans, and two island endemics, D. mauritiana and D. sechellia. A substantial amount of effort has gone into reconstructing the natural history of the complex, in part to infer the context in which functional divergence among the species has arisen. Researchers now provide evidence that both island species were isolated at about the same time, estimated at ~250,000 years ago.
Closing The Gap Between Fish And Land Animals

New exquisitely preserved fossils from Latvia cast light on a key event in our own evolutionary history, when our ancestors left the water and ventured onto land. Scientists have reconstructed parts of the animal and explain the transformation in the new issue of Nature.

Quotes:
We forfeit three-fourths of ourselves in order to be like other people.
Time is an illusion. Lunchtime doubly so.
In this life we get only those things for which we hunt, for which we strive, and for which we are willing to sacrifice.
