Seven days, lots of science in the news. Here’s this week’s roundup.

A new study finds that teenage girls vaccinated against HPV are no more likely to engage in risky sex than unvaccinated teens.

Attractive men, according to a new study out of Brunel University in London, tend to be less egalitarian, more selfish than their homelier peers.

They can’t read a book, but apparently dogs can read you. New research finds that our beloved canines can tell if you’re happy or angry just by looking at (part of) your face.

There’s probably dark matter in the core of the Milky Way.
