AP - Argentine rock star Gustavo Cerati was in intensive care Wednesday after undergoing brain surgery for a potentially fatal blood clot.

AFP - The late author J.G. Farrell was honoured Wednesday for his novel "Troubles" 40 years after it was first published, in an unusual take on Britain's most prestigious literary award, the Booker Prize.

A new study indicates that human generosity may have a limit, even when being generous would fulfill our selfish tendencies too. In an economic game where investing all available resources in cooperation with others gave the largest possible reward, players would still hold back from contributing everything they had, and continued to view their collaborators as potential competitors. Our ability to cooperate appears to have definite limits, just as our selfishness does.

Many scientists have suggested that humans cooperate as well as we do because of natural selection. When a person could only do so much sabre-tooth-tiger killing or berry-gathering in a day, cooperating and exchanging goods gave groups of humans a competitive edge over other species. Observing this tendency in studies lead some researchers to conclude that we have a predilection for engaging in as much cooperation as we can get back in return. The new work suggests that those study designs may have been flawed.
