Who's a chubby little water bear? Yes you are. Ooh, yes you are.
This moment of straight-up cuteness is brought to you by Bob Goldstein, who researches tardigrades at the University of North Carolina Chapel Hill.
Tardigrades are, of course, microscopic animals that live in moss and the muddy sand on beaches. They can survive high temperatures, freezing, and crushing pressures by drying themselves up into a little hard ball, called a tun. Stick a tun in water and — no matter what horrible conditions it's dealt with — it will rehydrate and regenerate back into a tardigrade. Beyond that, though, we know shockingly little about these animals. Even their place on the evolutionary tree of life is up for debate. Among other work, Goldstein and his team are in the process of sequencing the tardigrade genome. It may well be the most adorable genome on Earth.
