Stem cells can self-renew, meaning they can divide and create exact copies of themselves. elaborate
Some astrobiologists believe that life on other planets might be based on different elements than carbon, potentially silicon. elaborate
Cryobiology involves techniques to cool biological materials down to extremely low temperatures, sometimes even below -196°C (the boiling point of liquid nitrogen), preserving them for later use. elaborate
Some xenobiologists theorize that life on other planets might be based on silicon instead of carbon, due to silicon's similar chemical properties. elaborate
