The cell's internal skeleton undergoes constant restructuring. Physicists show that its associated proteins can be efficiently transported to their sites of action by diffusion - provided they can be arrested when they get there.
Bacteria are programmed using synthetic biology to release gas to report when they exchange DNA through horizontal gene transfer, the process by which organisms share genetic traits without a parent-to-child relationship.
Microalgae hold tremendous potential for industrial biotechnology. They are an important resource in the production of food and medications, and in many other applications. In comparison to bacteria and fungi, however, they still play only a minor role.
