Flu Virus Trots Globe During Off Season, Mixes With Other Viral Strain
The influenza A virus does not lie dormant during summer but migrates globally and mixes with other viral strains before returning to the Northern Hemisphere as a genetically different virus, according to biologists who say the finding settles a key debate on what the virus does during the summer off season when it is not infecting people. Bungled Insulin Production May Be A Culprit In Diabetes, University Of
Like pieces of origami that get mangled during folding, some insulin molecules get produced in bungled forms -- as well as the correct form -- inside the cells of the pancreas, new research shows. Model Models
Chemists are building new bridges between models and proteins. Novel Experiment Documents Evolution Of Genome In Near-real Time
UCSD bioengineers report in the November issue of Nature Genetics rapid evolutionary changes in a bacterial genome, observed in near-real time over a few days. Scientists have previously published static "snapshots"of the genome sequences of more than 100 bacterial species, but this new report shows how these genomes are moving targets. Laser Joining Of Solar Cells
A single solar cell produces a relatively low output -- it's a case of strength in numbers. Tiny strips of metal are used to link cells together. If the laser soldering temperature is too high, the solder joint may fracture. A new system provides automatic temperature regulation. Teamwork is what matters -- even in the case of solar cells: To obtain sufficient power to operate a pocket calculator, parking ticket dispenser or photovoltaic module, sunlight has to be captured simultaneously by an array of cells. Cassini Finds Recent And Unusual Geology On Enceladus
NASA's Cassini spacecraft has obtained new, detailed images of the south polar region of Saturn's moon Enceladus. The data reveal distinctive geological features and the most youthful terrain seen on the moon. These findings point to a very complex evolutionary history for Saturn's brightest, whitest satellite. [Ironic] LONDON: A jailed cocaine dealer is working as Santa Claus on
John Tams, who dons beard, boots and red suit to work in a cafe's Christmas grotto, said he wanted to give something back to the community... Terri Schiavo Case: Legal Issues Involving Healthcare Directives, Deat

Prediction Markets Accurately Forecast Influenza Activity
Influenza experts have borrowed a page from economists, creating a futures market for influenza activity that predicted outbreaks two to four weeks in advance. The influenza prediction market is presented in the January 15 issue of Clinical Infectious Diseases. Pleasure And Pain: Study Shows Brain's 'Pleasure Chemical' Is Involved
For years, the brain chemical dopamine has been thought of as the brain's "pleasure chemical,"and studies have linked the addictive properties of drugs like cocaine to their effects on the dopamine system. But now, a new study adds a new twist to dopamine's fun-loving reputation: pain.
