Here is more about the author of the article, German professor Tautz:

http://www.biozentrum.uni-wuerzburg.de/index.php?id=members0&personid=340

it is his website
http://www.beegroup.de/

the site is with frames, so I can't put the url of the article in this 
email, but you can find something about research, with pictures ( Heater 
bees active in the brood region of the nest.) on

BEEgroup > Die BEEgroup > Research Projects > Sociophysiology
