The invention of the breakfast cereal

John Harvey Kellogg (1852–1943) was an American physician who worked to develop a healthy diet. Kellogg and his brother Will Keith Kellogg invented several food items from grains. These eatables were rolled and made into sheets of dough, which were cooked. One day they accidentally left the cereals exposed for a longer period of time, and when these were passed through the rollers, they emerged as flakes. This marked the invention of cereal flakes, which also came to be known as wheat flakes and corn flakes.

The relation between butterflies and climate change

Butterflies are delicate creatures and they are affected by climate change. A large population of butterflies indicates a healthy ecosystem and a dearth of butterflies indicates that the ecosystem is under stress. Butterflies are unable to fly if their body temperatures drop below 30 degrees Celcius.
