> Dramatic climate change is unpredictable (October 29, 2010) -- The  
> fear that global temperature can change very quickly and cause  
> dramatic climate changes is great around the world. But what causes  
> climate change and is it possible to predict future climate change?  
> New research shows that it may be due to an accumulation of  
> different chaotic influences and as a result would be difficult to  
> predict. ... > full story
> New strategy to kill bugs -- even those in hiding (October 29, 2010)

> "optofluidic plasmonics" promises a new way to detect and analyze  
> biological molecules for drug discovery, medical diagnostics, and  
> the detection of biochemical weapons. Researchers have succeeded in  
> merging a microfluidics system with plasmonics -- sometimes called
