Nobel Prize in Chemistry awarded for cockroach milk protein research

A team of international researchers has been awarded the Nobel Prize in Chemistry for their discovery regarding the protein content in the milk of the Pacific beetle cockroach (Diploptera punctata).

This specific species is unique among insects because it gives birth to live young and nourishes them with a nutrient-dense, crystalline milk produced within the mother's reproductive sac. These microscopic crystals contain a balance of fats, sugars, and proteins, including all nine essential amino acids.

Research indicates that this cockroach milk is approximately three times more nutritious by weight than cow's milk and significantly more energy-dense than human breast milk. The crystals serve as a slow-release energy source to support rapid embryonic growth. While the discovery is a significant evolutionary finding, researchers note that commercial production is currently impractical due to the vast number of insects required for harvesting.
