Tardigrades are excellent at adapting to harsh environmental conditions. Back in 2019, Ralph Schill, a professor at the Institute of Biomaterials and Biomolecular Systems at the University of Stuttgart, proved that anhydrobiotic (dried) tardigrades can survive undamaged for many years without absorbing water. Whether they age faster or slower in a frozen state, or whether aging even comes to a halt, was previously unclear. But the mystery has now been solved: Frozen tardigrades do not age.
