First genome comparison of plankton species yields surprises underlying key ocean processes
04-30-2007 · EurekAlert!An international team of scientists led by Scripps Institution of Oceanography at UC San Diego and the Department of Energy's Joint Genome Institute has peered into the genetic makeup of two species of phytoplankton, the tiny plants key in global photosynthesis and carbon cycling, and come away with surprising results about evolutionary engineering and new ideas about the role that a poorly understood chemical element may play in the world's oceans.

- Puzzling plankton yield secrets to role in evolution/global photosynthesis
04-30-2007 · EurekAlert!
The analysis of DNA sequences from tiny green algae have provided new insights into the mystery of how new species of plankton evolve -- and further highlights their critical role in managing the global cycling of carbon. These findings, by a group led by the DOE Joint Genome Institute; the Scripps Institution of Oceanography, University of California, San Diego; and the Pierre & Marie Curie University, were published this week in PNAS.

- 'Telepathic' genes recognize similarities in each other
01-24-2008 · EurekAlert!
Genes have the ability to recognize similarities in each other from a distance, without any proteins or other biological molecules aiding the process, according to new research published this week in the Journal of Physical Chemistry B. This discovery could explain how similar genes find each other and group together in order to perform key processes involved in the evolution of species.

- Hypnosis study reveals brain's 'amnesia centers'
01-09-2008 · EurekAlert!
Brain scans of hypnotized people that are taken as they forget and are triggered to remember have revealed neural circuitry that is key to the memory suppression and recall process. The researchers who conducted the study said their insights into the memory suppression and recall process may yield insight into the mechanisms underlying amnesia.

- Soil nutrients shape tropical forests, large-scale study indicates
01-11-2007 · EurekAlert!
Tropical forests are among the most diverse plant communities on earth, and scientists have labored for decades to identify the ecological and evolutionary processes that created and maintain them. A key question is whether all tree species are equivalent in their use of resources -- water, light and nutrients -- or whether each species has its own niche.A large-scale study by researchers at the University of Illinois at Urbana-Champaign and eight other institutions sheds some light on the issue.

- Neanderthal genome sequencing yields surprising results and opens a new door to future studies
11-15-2006 · EurekAlert!
The veil of mystery surrounding our extinct hominid cousins, the Neanderthals, has been at least partially lifted to reveal surprising results. Scientists with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the Joint Genome Institute (JGI) have sequenced genomic DNA from fossilized Neanderthal bones.

- Beyond a 'speed limit' on mutations, species risk extinction
10-01-2007 · EurekAlert!
Harvard University scientists have identified a virtual "speed limit" on the rate of molecular evolution in organisms, and the magic number appears to be six mutations per genome per generation -- a level beyond which species run the strong risk of extinction as their genomes lose stability.

- Fighting like a girl or boy determined by gene in fruit flies
11-19-2006 · EurekAlert!
Fighting like a girl or fighting like a boy is hardwired into fruit fly neurons, according to a study in the November 19 Nature Neuroscience advance online publication by a research team from Harvard Medical School and the Institute of Molecular Pathology in Vienna. The results confirm that a gene known as "fruitless" is a key factor underlying sexual differences in behavior.
