00:46 Synthetic cells made from bacterial bits

For years researchers have been interested in creating artificial cells, as they could be useful for manufacturing compounds and understanding how life works. Now a new method shows how this can be accomplished using polymer droplets that integrate components of burst bacteria. The synthesised cells are able to perform translation and transcription and have several features that resemble real cells, like a proto-nucleus and a cytoskeleton.
