Earthquake engineering is hard.
I would love to have robot colleagues. I don't think robots will take my job, but one day in the future I'm sure robots and humans will both be working side-by-side in the world of journalism. The only difference is that the robots won't have to live on ramen during the long years while they establish their careers.
That's a really good point. I should have included Adventure Time on this list!
Thank you so much for coming in to talk to us today. My first question is about the way we tend to imagine that the behaviors and habits that are "most healthy" for humans should reflect how we lived while we were evolving — roughly 100-50 thousand years ago. In Paleofantasy, you do a great job debunking this idea.
Ask biologist Marlene Zuk anything you want about human evolution
Marlene Zuk is an evolutionary biologist, and the author of the new book Paleofantasy: What Evolution Really Tells Us About Sex, Diet, and How We Live. It's a cogent and funny look at common myths about human evolution. Today she's here from 12-1 PM Pacific Time to talk to you about evolution.
According to NASA's website, these are "approximately true colors." Meaning yes, this is what you would see in visible light.
Sometimes they do enhance the colors, usually to show areas that are hotter than others. Other times astronomers take very long exposures, or they layer many exposures on top of each other, to show the colors. But the colors really are out there — it's just that we can't see them with the naked eye.
The Ring Nebula, a massive cloud of gas around a dying star, is one of the best-known celestial objects. Not only is it gorgeous, but it's easy to find in a telescope, even if you're an amateur. This new Hubble image is anything but backyard astronomy, however — and it's given astronomers a new understanding of the nebula's shape in space.
