Some of our most advanced medicines today rely on components derived from living organisms. These therapeutics, called biologics, include things like vaccines, blood products like Human Blood Clotting Factor VIII (FVIII), antibodies and stem cells. Biologics are incredibly temperature sensitive, which means they need to be kept cold during production, transport and storage, a process collectively called the cold chain. The stringent transport and storage temperature requirements for biologics create a barrier to accessing these lifesaving options; particularly for those in remote or underdeveloped regions, where maintaining a cold chain is logistically difficult and costly.
But what if we could break the cold chain? Inspired by one of the most resilient creatures on Earth – the tardigrade – scientists at the University of Wyoming are exploring ways to do just that.

Everyone has their favorite microscopic creature—you all do have a favorite, right? Mine is unquestionably the tardigrade. Tardigrades, also called water bears or moss piglets, are microscopic invertebrates that are composed of five segments: one head segment and four body segments, each with a pair of legs. They are 0.1–1.2mm in length, making them easy to see under low magnification, and have a brain and well-developed nervous system. Tardigrades are found in just about every environment on earth. Termed “extremophiles”, they have adapted to survive in even extremely harsh environments. Your neighborhood pond? The Himalayas? Antarctica? Deep sea? Tardigrades live in all those places.
