Persistence makes the difference in minority participation in science, researchers say
The problem of persistence has long troubled undergraduate programs hoping to guide promising students from underrepresented racial/ethnic groups into science careers, but a new study by science education researchers at the University of Wisconsin says that the problem appears to be translating students' initial interest into confidence that they can proceed in science.
Large human brain evolved as a result of 'sizing each other up'
Humans have evolved a disproportionately large brain as a result of sizing each other up in large cooperative social groups, researchers have proposed.

#524 The Human Network
What does a network of humans look like and how does it work? How does information spread? How do decisions and opinions spread? What gets distorted as it moves through the network and why? This week we dig into the ins and outs of human networks with Matthew Jackson, Professor of Economics at Stanford University and author of the book "The Human Network: How Your Social Position Determines Your Power, Beliefs, and Behaviours".
