UC San Diego: Artificial Cell Membranes

January 31st, 2012

“Specifically, robots, engineered organisms, and nanobots share a dangerous amplifying factor: They can self-replicate. A bomb is blown up only once – but one bot can become many, and quickly get out of control.”

Bill Joy, Why the Future Doesn’t Need Us

Via: UCSD:

Chemists have taken an important step in making artificial life forms from scratch. Using a novel chemical reaction, they have created self-assembling cell membranes, the structural envelopes that contain and support the reactions required for life.

Neal Devaraj, assistant professor of chemistry at the University of California, San Diego, and Itay Budin, a graduate student at Harvard University, report their success in the Journal of the American Chemical Society.

“One of our long term, very ambitious goals is to try to make an artificial cell, a synthetic living unit from the bottom up – to make a living organism from non-living molecules that have never been through or touched a living organism,� Devaraj said. “Presumably this occurred at some point in the past. Otherwise life wouldn’t exist.�

By assembling an essential component of earthly life with no biological precursors, they hope to illuminate life’s origins.

“We don’t understand this really fundamental step in our existence, which is how non-living matter went to living matter,� Devaraj said. “So this is a really ripe area to try to understand what knowledge we lack about how that transition might have occurred. That could teach us a lot – even the basic chemical, biological principles that are necessary for life.�

    “In 1837, Andrew Crosse reported to the London electrical Society concerning the accidental spontaneous generation of life in the form of Acurus genus insects while he was conducting experiments on the formation of artificial crystals by means of prolonged exposure to weak electric current.”

    it is not that the knowledge is “lacked” but that it is not believed. because it is not ours.
