In this episode:
00:44 Fungi, insects, dead trees and the carbon cycle
Across the world forests play a huge role in the carbon cycle, removing huge amounts of carbon dioxide from the atmosphere. But when those trees die, some of that carbon goes back into the air. A new project studies how fast dead wood breaks down in different conditions, and the important role played by insects.

Home prices in the U.S. have climbed at a record pace during the pandemic. The median home price reached over $363,000 in June 2021, a 23.4% increase from 2020.

Type 1 and type 2 diabetes are characterized by increased blood glucose levels. They affect almost half a billion people around the globe, and this number is projected to rise as we reach the middle of the century. In most individuals, blood glucose levels are kept within a healthy range by a hormone called insulin, which is secreted by the pancreas, but this fine-tuned regulation can go wrong in type 1 and type 2 diabetes. In this animation, we lay out our current understanding of these diseases and explore active areas of research that aim to restore the body’s blood glucose control.
