Human-engineered microbes are workhorses of the pharmaceutical and chemical industries, churning out biofuels, drugs, and many other products. But they can cause big problems if they become contaminated by other microbes or viruses or escape into the environment. Now, a new type of microbe that can survive only on artificial nutrients promises better security against such mishaps. The strategy, described in two papers in this week's issue of Nature, might ultimately be used to control genetically engineered plants or other organisms released into the wild to create products or clean up pollution.

The conclusion is that the high-fat diet triggered chronic inflammation, which in turn triggered an autoimmune response in the mice's central nervous systems. Normally this response protects the brain from invaders like bacteria, but a high-saturated fat diet knocks the process off track, resulting in damage to synapses in the brain - specifically in the hippocampus. Since the hippocampus is a brain area central to memory and learning, the eventual outcome is impaired brain function. In short, the high-fat diet caused brain damage.
