Scientists have known for more than 200 years that vision begins with a series of chemical reactions when light strikes the retina, but the specific chemical processes have largely been a mystery. A team of researchers from the United States and Switzerland say they have shed new light on this process by "capturing" this chemical communication for future study and say it may lead to the development of new treatments for some forms of blindness and vision disorders. 
Researchers at the University of British Columbia have discovered a mimic of one of "nature's antibiotics" that can be used to coat medical devices to prevent infection and rejection.   The study, released today in the journal Chemistry and Biology, found that a synthetic form, short tethered cationic antimicrobial peptides (cationic peptide), can protect surfaces, like those of medical devices, killing bacteria and fungi that come into contact with them. Peptides are small proteins.
A study of college freshmen in the United States and in China found that Chinese students know more science facts than their American counterparts but both groups are nearly identical when it comes to their ability to do scientific reasoning - unfortunately neither group  was very good at it.

The lesson is that educators must go beyond teaching science facts if we hope to produce voters, policy makers and scientists who can make reasoned choices.

In its January/February issue of Science Watch, Thomson Reuters analyzes 12 year's worth of data from its National Science Indicators database to determine the U.S.'s global scientific influence based on the nation's research output and impact.

In 2007 chocolate was all the rage, with Mars, Inc.-funded scientists even having their own panel at the AAAS meeting.  In 2008, blueberries were the rage.    

In 2009, says Dr. Luis Cisneros, Texas A&M AgriLife Research food scientist, "Stone fruits are super fruits, with plums as emerging stars."
