This week on UnDisciplined, we've gathered two of our favorite fellow science geeks to talk about the headlines that caught our eyes in June — and a few we wish would have gotten more attention.

This week on UnDisciplined, we're going to talk about the factors that influence our moods. How do the institutions around us inspire us to take action? And how do the things we put into our bodies impact the way we see the world?

This week on UnDisciplined, we're going to chat with a scientist who is trying to solve a big challenge: engineering blood vessels for transplantation into human bodies. After that, we'll talk to a researcher who is trying to solve a challenge that might be even bigger: reducing gender pay disparities in corporate America.

This week on UnDisciplined, we're talking to researchers on two sides of a huge scientific challenge. Our first guest researches climate — that means she only has one test subject to work with: the Earth. Our second guest studies cancer, which presents differently in humans and other organisms. That means she has endless test subjects.

This week on UnDisciplined, we're talking about artificial intelligence, great white sharks, illegal pollution, snail genes, and new rules for leaders at the National Institutes of Health. That's right, it's the May Science News Roundup.

This week on UnDisciplined, we're talking about scientific puzzles. For instance, why is it that hundreds of tree species can exist within a single acre of rainforest, but the same species is almost never found next to itself?

This week on UnDisciplined, we're talking about biofuels ... and tattoos.

This week on UnDisciplined, we're talking about math education and ... zombies?

Our world often seems to be really divided, particularly across cultures in which everyone seems to play by different rules. But today we're going to hear from a researcher who believes there are actually seven universal moral rules that have been embraced by pretty much every society.

This week on UnDisciplined, we're talking about black holes, pig brains, and water on the moon as we round up the most intersting, important, and awe-inspiring science stories from the past month with an amateur astronomer, an environmental epigeneticist, and a podcasting paleontologist.
