But we still don't know if silicon-based life forms exist at all, or what they would look like. The origins of life on Earth There are competing hypotheses about how life arose on Earth.

However, the universe may harbour life forms based on entirely different principles and biochemistries. Life elsewhere could use different elements as building blocks. Silicon, with its chemical ...

Scientists have coaxed life to do something it has never done before: bond silicon to carbon. You're probably already familiar with a few products products that use carbon-silicon, or ...
