Scientists working to replicate the harsh conditions of space, with its cold temperatures, radiation and lack of air,have managed to get artificial cell membranes to form, proving that life could have originated in space. For life toexist in cellular form, each cell must be surrounded by a protective membrane. These cells then combine together to form complex life structures.
The membranes resemble primitive cell walls. David Dreamer, a biologist at the University of California at Santa Cruz,said, “This wall is semi-permeable, so that things like water and oxygen can get in and out very easily. That is whatlife requires-it needs to have an inside that is not totally shut off from the outside.”
