    Multicellular micro-organism found to have survived for 24,000 years in cryptobiosis under the Siberian permafrost, and it could still still reproduce asexually after being thawed!

      Reproduce asexually? Is that what they’re calling it these days? Not surprising that that’s the first priority upon waking from a 24000 year coma.

      Education is extremely important.

          Wow. I'm also impressed that the cells can survive being freezed.

            Cells are frozen all the time. In our institutions T cell therapy program for TILs and CARs we freeze Cell lines on a regular basis.

            I think the issue here is the time frame and that it’s a multicellular organism.

              But isn't it usually the case that, unless special precautions are taken, the ice crystals destroy the cell?

                Honestly I’m not a lab person so I don’t know the details but cryopreservation is pretty standard.

                  To thaw out red cells, we use a glycerin wash, followed by a couple of saline washes.

                  Rare types (yes, we have a local family of Bombay Rh null) can be stored for years.
