Envisat captures first image of Sargassum from space

...rophyll from space, therefore, provides a valuable tool for modelling primary productivity. "The 709 band used by MERIS is not present on other ocean-colour sensors. It was essential to our detecting Sargassum," Gower said. "The MCI index has allowed us to find so many interesting things, including Sa...

New collaborative research reveals chimpanzees can sustain multiple-tradition cultures

...tional collaborative research team taught forms of tool use and food extraction techniques to high-ranking individuals in four different captive chimpanzee communities. Researchers then observed as those individuals passed on the techniques to other members of their communities. The researchers included F...

Nurtured chimps rake it in

...t also whether they understood the reasons why the tool worked. The researchers gave the animals access to small rakes with either a rigid wooden head or a flimsy fabric head. Both enculturated and semi-enculturated chimpanzees correctly chose the rigid rake which enabled them to obtain the reward, in...
