| Unusual 'tulip' creature discovered Posted: 18 Jan 2012 02:36 PM PST A bizarre creature that lived in the ocean more than 500 million years ago has emerged from the famous Middle Cambrian Burgess Shale in the Canadian Rockies. Officially named Siphusauctum gregarium, fossils reveal a tulip-shaped creature that is about the length of a dinner knife (approximately 20 centimeters or eight inches) and has a unique filter feeding system.  |
| Important gene-regulation proteins pinpointed by new method Posted: 18 Jan 2012 10:23 AM PST A novel technique precisely pinpoints the location of proteins that read and regulate chromosomes. The order of these proteins determines whether a brain cell, a liver cell, or a cancer cell is formed. Until now, it has been exceedingly difficult to determine exactly where such proteins bind to the chromosome, and therefore how they work. The new technique has the potential to take high-resolution snapshots of proteins as they regulate or miss-regulate an entire genome.  |
| Posted: 18 Jan 2012 08:17 AM PST A new study demonstrates how introducing certain polymers—like those found in human mucus and saliva—into an aquatic environment makes it significantly more difficult for ulcer-causing bacteria and other microorganisms to coordinate.  |
| Good parents are predictable, at least when it comes to corn Posted: 15 Jan 2012 10:59 AM PST According to a relatively new insight in plant research, there is no single gene strongly controlling growth. Nevertheless, in order to breed new varieties of corn with a higher yield faster than ever before, researchers are relying on a trick: early selection of the most promising parent plants based on their chemical and genetic makeup, as well as on new statistical analysis procedures.  |
