We have a new podcast! It's called Universe Of Art, and it features conversations with artists who use science to bring their creations to the next level. Listen on Apple Podcasts, Spotify, or wherever you get your podcasts. 

Despite social media’s early promises to build a more just and democratic society, over the past several years, we’ve seen its propensity to easily spread hate speech, misinformation and disinformation. Online platforms have even played a role in organizing violent acts in the real world, like genocide against the Rohinga people in Myanmar, and the violent attempt to overturn the election at the United States capitol.

But how did we get here? Has social media fundamentally changed how we interact with the world? And how did big tech companies accumulate so much unchecked power along the way?

Americans haven’t always loved whales and dolphins. In the 1950s, the average American thought of whales as the floating raw materials for margarine, animal feed, and fertilizer—if they thought about whales at all. But twenty-five years later, things changed for cetaceans in a big way. Whales became the poster-animal for a new environmental movement, and cries of “save the whales!” echoed from the halls of government to the whaling grounds of the Pacific. What happened?

Shifting attitudes were due, in large part, to the work of scientist Roger Payne, who died earlier this month at the age of 88. His recordings helped to popularize whalesong, and stoked the public imagination about intelligent underwater creatures who used vocalizations to communicate.

In 2018, our podcast “Undiscovered” explored the history of Payne’s work, and that of his colleagues. We’re featuring this episode as a way of remembering his life and groundbreaking work.
