Ed Boyden is the head of the MIT Media Lab’s Synthetic Neurobiology research group and he wants blow up the brain. Sort of. He and his team have discovered a way to examine brain tissue by physically expanding it—a process that lets them look at tissue which would normally be extremely difficult to see even under a microscope. Boyden explains how it all works—and a lot more—on this week’s episode.

Brian Fisher is really into ants. And after listening to him talk about them on this week’s show, I suspect he might convince you to appreciate them more than you probably do right now.
Fisher is an entomologist at the California Academy of Sciences and we talk to him about all things ants—from how many “words” they can use, to how we can use them to figure out what parts of forests are most important to protect.
We also have a huge announcement this week: Our new permanent co-host is Kishore Hari!

Dark matter: it makes up 80 to 85 percent of the matter in the universe, it’s invisible, you can’t touch it, and according to this week’s guest astrophysicist Katie Mack, it’s probably passing through you right now.
Dark matter is weird.
On the show this week Indre talks to Mack about dark matter, dark energy, and the big bang.

On the show this week we talk to Matt Walker, Principal Investigator at UC Berkeley’s Sleep and Neuroimaging Lab. Walker opens our eyes to exactly how important (and bizarre) sleep is—from the insane effects not sleeping enough can have on you both physically and cognitively, to the fact that, after having fought through ages of natural selection, it’s amazing our brains still need it at all.
