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.

Genetic and biotechnology can improve food security, the environment and public health. Yet dramatic innovation can lead to unintended consequences and present ethical challenges. In theory, the study of genetics and related cutting edge sciences are widely celebrated. But in practice, the words "gene" and "genetic engineering" often stir fear and misunderstanding when applied to biomedicine and farming. Intricate science scares people who don't understand risk and complexity. What is the potential of agricultural and human genetics? The commitment of the GLP is to promote public awareness of genetics and science literacy.

First, surgeons remove the uterus and part of the vagina from the donor - in this case, one who was deceased, since it is a risky surgery that involves separating uterine blood vessels that are tightly wrapped around the tubes from the bladder. Next, the uterus is transferred to the living recipient. Surgeons connect an artery and a vein on either side of the uterus to connect it to the recipient's blood supply. A piece of the donor's vaginal tissue is attached to the recipient's vagina, and supporting tissue is attached to the pelvis to secure the organ in place. It's not necessary to connect any nerves.

4:51 video What's tasty, abundant and high in protein? Bugs! Although less common outside the tropics, entomophagy, the practice of eating bugs, was once extremely widespread throughout cultures. You may feel icky about munching on insects, but they feed about 2 billion people each day (Mmm, fried tarantulas). They also hold promise for food security and the environment. Emma Bryce makes a compelling case for dining on bugs.
