Pixar has been breaking technical barriers since it was founded in 1986. But talk to any of their top filmmakers and they’ll tell you that a focus on story and characters has been the true key to the studio’s success. Now, storytellers looking to improve their craft have a chance to learn from the masters. As TechCrunch reports, Pixar has teamed up with the online education service Khan Academy to release a six-part free course titled “The Art of Storytelling.”

The course marks the third season of Khan Academy’s “Pixar in a Box” series, following previous lessons on subjects like color science, virtual cameras, and character modeling. In this class, remote students will receive lessons from some of the brightest minds to work for Pixar. They include Brave (2012) screenwriter and director Mark Andrews; Up (2009), Inside Out (2015), and Monsters, Inc. (2001) director Pete Docter; and “Sanjay’s Super Team” director and Ratatouille (2007) animator Sanjay Patel.

The first lesson provides an introduction to storytelling complete with videos and activities to coach you through each section. Lessons on character building, storyboarding, emotional appeal, and more will roll out on Khan Academy throughout the year. You can watch a teaser for the course below.

Scientists say the turbulent waters of the lower Congo River divided one fish family so thoroughly that it split into several different species. The researchers published their findings in the journal Molecular Ecology.

One 200-mile stretch of the river has a peculiar claim to fame—it’s become a sort of evolutionary playground, boasting more than 300 different species of fish alone. “In this very short section of the Congo, we find a tremendous diversity of fishes,” co-author Melanie Stiassny of the American Museum of Natural History said in a statement.

At a mere 3 to 5 million years old, Stiassny said, this segment of the river is still relatively young. “So what is it about this system that makes it such a pump for species?”

New species are formed when an existing species is split into two populations, often by some sort of insurmountable physical barrier. Over thousands of years, the different environments and pressures faced by the two populations will be so different that they’ll evolve into two separate species.

But there are currently no major dams in this section of the Congo, nor does the river branch or trickle off into lakes. The fish are all essentially swimming in the same body of water.

Stiassny and her colleagues had a theory: The behavior of the water itself had broken fish families apart. To test their hypothesis, they collected 53 fish, all members of the genus Teleogramma, from different sections of the strange 200-mile stretch. The researchers sequenced the fishes’ DNA and compared their bodies, looking for similarities and differences.

There were plenty of differences. Within those 53 fish the researchers had representatives of all five Teleogramma species [PDF]. But some of those species were practically living on top of one another—sometimes less than a mile apart. But there was always something between them: roiling river rapids.

Lead author Elizabeth Alter, of CUNY York College and AMNH, said the rapids are working the same way a wall or a mountain might, keeping the fish populations separate. “What’s particularly unique about the lower Congo is that this diversification is happening over extremely small spatial scales,” she said in the statement. “There is no other river like it.”

The fish may be facing even greater barriers in the near future, as the region has been proposed as the site of a new dam—a situation that Stiassny says would “majorly disrupt” this extraordinary ecosystem.
