There are now over one billion automobiles on the road worldwide. An explosion in the auto markets in China and India ensures that number will increase, with China supplanting the United States as the world's largest car market. It's fair to say humanity has a love affair with the car, but it's a love-hate relationship. Cars are at once convenience, art, and menace. People write songs about their vehicles, put them in museums, race them, and wrap their identities up in them. About 15% of carbon dioxide emissions from the burning of fossil fuels comes from cars. Traffic fatality estimates vary from half a million per year to more than double that. Gathered here are images of the automobile in many forms, and our relationship to and dependence on our cars. This is the second in an occasional Big Picture series on transportation, following Pedal power earlier this year. -- Lane Turner (40 photos total)

It's time once more for a look into the animal kingdom and our interactions with the countless other species that share our planet. Today's photos include researchers dressed in panda costumes, a massage given by an African snail, a 39-pound cat named Meow, a Japanese macaque with hay fever, and orangutans having a playdate using FaceTime on an iPad. These images and many others are part of this roundup of animals in the news from recent weeks, seen from the perspectives of their human observers, companions, captors, and caretakers, part of an ongoing series on animals in the news.
