Did you know our muscles are composed of many cells capable of contraction or relaxation?

For a resting muscle to contract, it has to get energy from sugar and glucose. Glycogen releases glucose, which is the body's storage form of sugar.

Edwin Krebs and Edmond Fischer showed how proteins in the muscle cell rapidly make the energy supply accessible for muscular work and how the breakdown of glycogen to glucose is controlled in the skeletal muscles so that the energy supply matches energy demand. Their basic discoveries were made in the mid-1950s through studies of a special muscle system and attracted little attention at the time.

Krebs and Fischer shared the 1992 Nobel Prize in Physiology or Medicine for their discovery.

John Goodenough made crucial contributions to the battery industry. In 1980 he developed a lithium battery with a cathode of cobalt oxide, which, at a molecular level, has spaces that can house lithium ions. This cathode gave a higher voltage than earlier batteries. Goodenough's scientific contributions were crucial for the development of lithium-ion batteries, which are today used in mobile phones and electric cars.

Goodenough was the oldest person to receive a Nobel Prize when he received the chemistry prize in 2019 for developing lithium ion batteries.
