Great Barrier Reef can see a world beyond the rainbow that is 
invisible to other animals, scientists said on Wednesday.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://uk.reuters.com/article/oddlyEnoughNews/idUKL132374120080514?feedType=RSS&feedName=oddlyEnoughNews"><P> They view the world in up to 12 primary colors -- four 
times as many as humans -- and can measure six different kinds 
of light polarization, Swiss and Australian researchers 
reported.</P><SPAN id="midArticle_2"></SPAN>
<P> polarization is the direction of oscillation in light 
waves.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://uk.reuters.com/article/oddlyEnoughNews/idUKL132374120080514?feedType=RSS&feedName=oddlyEnoughNews"><P>Some of the animals they like to eat are transparent and 
quite hard to see in sea-water, except they're packed full of 
polarizing sugars. I suspect they light up like Christmas trees 
as far as these shrimp are concerned," said Andrew White of the 
University of Queensland.</P><SPAN id="midArticle_5"></SPAN>
<P> And the shrimps probably use tiny changes in color and 
polarization to send sexual signals between males and females, 
the researchers believe.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://uk.reuters.com/article/oddlyEnoughNews/idUKL132374120080514?feedType=RSS&feedName=oddlyEnoughNews"><div align="center"><img src="http://content9.clipmarks.com/blog_cache/uk.reuters.com/img/F6494A8C-D31D-4B3F-8E41-62447A644D6A" alt="Photo" /></div></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/FD35913C-7DC6-4FE0-BD70-1E74BB8AAC83/blog/" title="blog or email this clip"><img src="http://content6.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
