Episode notes

Sara Wikstrom, a sol biologist who's been writing about chen's paper in a newton views article. Chen proposes that one part of the mechanism might be to do with the skin cells getting a bit stretched as the animal grows quickly. This tension could open certain iron channels that potent signal to themselves that they should undergo this curious division.

00:56 How video calls can reduce creativity

As a result of the pandemic, workers around the world have become accustomed to meeting colleagues online. To find out if this switch from face-to-face meetings came at a cost to creativity, a team compared the number of ideas generated by workers collaborating either online, or in-person. They showed that people meeting virtually produced fewer creative ideas than those working face-to-face, and suggest that when it comes to idea generation maybe it’s time to turn the camera off.

10:34 Fish skin reveals a new type of cell division

Researchers looking at the skin cells of zebrafish have discovered a new type of cell division, which doesn’t require DNA replication. DNA is usually essential for healthy cells, but the researchers think this puzzling finding may be a temporary measure to help the fish produce skin more rapidly during growth spurts.
