They put the tardigrades onto surfaces cooled to below -226 degrees Fahrenheit (-143 degrees Celsius), and covered the tiny creatures in anisole, an anise-scented organic compound.
If it's not enough that they froze them, then they covered them in licorice flavor and tattooed them with it. I literally didn't realize you could torture something so.
only around 40% of the tardigrades survived, but the researchers say this could improve with further refinement. Nevertheless, the study suggests that researchers could use this method to print microelectronics or sensors onto living tissue.
“This approach provides new insights into tardigrades’ resilience
The only thing that can kill tardigrades are tattoos.
