Ionic Liquids Could Form Naturally And Replace Water As A Biological Solvent

Water is key to life as we know it. But that doesn’t mean its key to life everywhere. Despite the fact that the ability to house liquid water is one of the key characteristics we look for in potentially habitable exoplanets, there is nothing written in stone about the fact that life has to use water as a solvent as opposed to other liquid options. A new paper from researchers at MIT, including those who are developing missions to look for life on Venus, shows there might be an alternative - ionic liquids that can form and stay stable in really harsh conditions.
