In this week’s news roundup, Washington Post science writer Rachel Feltman tells us about a surprising insight gleaned from the Philae lander’s bouncy arrival on comet 67P/Churyumov-Gerasimenko. We’ll also hear about a self-powered digital camera that harvests light energy from its image sensor. And a new study suggests that the human bonding hormone oxytocin might play a role in human-canine relationships as well.

Plus, Anthony Leiserowitz of the Yale Project on Climate Change Communication gives us the good and the bad on the latest climate polling data. Good thing: Americans overwhelmingly support renewable energy investment, and want to regulate carbon dioxide as a pollutant. Bad thing: Most Americans still think scientists disagree about climate change—so the message about scientific consensus isn’t getting out.
