Why Hacking DNA Is the Secret of Deep-Space Travel

Scientists worldwide are rapidly increasing their ability to genetically re-engineer plants, animals, and microbes. Amor Menezes, an aerospace engineer and synthetic biology researcher at the University of California, Berkeley, argues that augmented organisms could transform long-term human space missions. Menezes and his research team just published an outline in the Journal of the Royal Society Interface on the six most promising applications for such engineered organisms. Here's how genetic engineering will revolutionize space travel.
