Coral reefs may look like colorful rocks, but they’re living animals that support entire ocean ecosystems. In this episode, Dr. Biology chats with professor Liza Roger, whose lab at Arizona at Arizona State University is home to corals, sea anemones, and some unusual upside-down jellyfish. Together…
It is surprising how much of the land on Earth is what scientists call drylands. You might think that these areas are not crucial to life on the planet, but in fact, they are. They are also some of the most challenging places to do research. Part of the challenge is what we see above ground is only…
Looking into the past can be strange and exciting. To understand a past that goes back millions of years, we often depend on the stories told by fossils. Dr. Biology talks with anthropologist Donald Johanson about Lucy, a fossil of human ancestors that has taught us some…
