They form communities with dominance hierarchies and subgroups. But while chimpanzees may be influenced by group mentality, they know a better deal when they see one. Researchers at Wolfgang Kohler Primate Research Center in Germany reported that when presented with a choice between rewards, logic, not popularity, prevailed. Edwin van Leeuwen and colleagues from the MPI's for Psycholinguistics and Evolutionary Anthropology devised an experiment to test the strength of social influences. Since things are going so well, the researchers decided to mix things up and see how the groups respond. The researchers stress that conformity still has a major role in chimpanzee social interactions in the wild.

e-book ligas The Ten Most Disturbing Scientific Discoveries Science can be glorious; it can bring clarity to a chaotic world. But big scientific discoveries are by nature counterintuitive and sometimes shocking. Here are ten of the biggest threats to our peace of mind. 1. The Earth is not the center of the universe. We’ve had more than 400 years to get used to the idea, but it’s still a little unsettling. … his contemporaries found his massive logical leap “patently absurd,” says Owen Gingerich of the Harvard-Smithsonian Center for Astrophysics. Galileo got more grief for the idea than Copernicus did. 2. Antibiotics and vaccines have saved millions of lives; without these wonders of modern medicine, many of us would have died in childhood of polio, mumps or smallpox. The influenza virus mutates so quickly that last year’s vaccination is usually ineffective against this year’s bug. 3. The concept of extinction took a while to sink in. Today, according to many biologists, we’re in the midst of a sixth great extinction.

How to Block a Surveillance Camera: A DIY Art Tutorial from Ai Weiwei by Maria Popova A wine opener usage George Orwell would approve of. “When things get tough,” Neil Gaiman advised on in his fantastic commencement address on the creative life, “this is what you should do: Make good art.
