Unfold UC Davis

Can communication with a humpback whale teach us how to talk to extraterrestrials? Researchers from UC Davis and the SETI Institute want to find out. In the waters of Southeast Alaska, scientists believe they’ve had what might be the very first human-whale communication. The interaction was designed to eventually help us detect and interpret signals coming from outer space. In this episode of Unfold, you’ll hear about the scientists’ remarkable 20-minute “conversation” with a humpback named Twain and what we can learn by studying nonhuman communication on Earth.

Imagine this: A man rubs a hormonal gel on his shoulders once daily, and after a few months his sperm count is zero, giving him and his partner peace of mind that they won’t conceive. That’s been the reality for one couple taking part in a clinical trial for male hormonal birth control at UC Davis Health – and around the world. In this episode of Unfold, we’ll learn more about how the gel works from the physician running the trial, and we’ll chat with the couple about how using the gel has changed their lives.

If you’ve ever asked Siri or Alexa something, you may have noticed you speak MORE LOUDLY, slowly or make your words “clear-er.” UC Davis researchers say most of us speak differently when talking to our devices. Voice artificial intelligence may even be changing our social behavior. In this episode of Unfold, we’ll talk to two UC Davis linguists to find out why voice AI is changing the way we operate.

You’ve probably heard of groundwater — the water stored underground in aquifers that is a critical natural resource for the western U.S. Did you know that in California, these aquifers provide nearly 40 percent of the water used by farms and communities? During a drought, that figure is even more — nearly 60 percent. Groundwater is vital for growing crops. But California is using this underground resource faster than it can be replenished. In this episode of Unfold, learn how UC Davis researchers are working to make groundwater more sustainable while also helping California remain the most productive agricultural state in the nation.

There are two kinds of people in this world: Those who love daylight saving time, and those who don’t. UC Davis Health sleep medicine expert Heinrich Gompf is not a big fan of the clock change — or at least not the way we currently do it in the United States. In this episode of Unfold, he tells us why it’s so darn difficult for our bodies to adjust to the time change (the suprachiasmatic nucleus!) and offers tips to help you prepare and adapt when we do spring forward.
