Researchers are using inexpensive components from ordinary liquid crystal display (LCD) projectors to control the brain and muscles of tiny organisms, including freely moving worms. Red, green and blue lights from a projector activate light-sensitive microbial proteins that are genetically engineered into the worms, allowing the researchers to switch neurons on and off like light bulbs and turn muscles on and off like engines.
An unusual galaxy with gas jets could explain how starforming galaxies become red and dead. University of California, Berkeley, astronomers may have found the missing link between gas-filled, star-forming galaxies and older, gas-depleted galaxies typically characterized as "red and dead."
The mega-mergers of 2009 did not continue into 2010. While the three biggest acquisitions in 2009 each had a price tag of more than $40 billion, only last year's top purchase got above that mark, according to an evaluation of reported deals conducted by Genetic Engineering & Biotechnology News (GEN) (http://www.genengnews.com/). The only other mega takeover for the year, sanofi-aventis' move to buy Genzyme, is still being worked out.
