Study establishes the first public collection of bacteria from the intestine of mice
Mouse models are extensively used in pharmaceutical and medical research, and the microbes in their intestine can have an impact on research.

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.
