People harbor more than 100 trillion microbes. These microbes live in various habitats on and within the human anatomy; the gut houses the densest population of all, containing hundreds of bacterial species.

Microbes have given us some devastating diseases, everything from the Black Death to cholera, syphilis, typhoid and the occasional yeast infection. But our microbial friends have also done us some good. Without microbes, we wouldn’t have wine and beer (something the Ancient Egyptians started producing some 6,000 years ago), nor much oxygen and fixated nitrogen, all essential for plant, animal and human life. And don’t forget antibiotics, fine cheeses and the rest.

Jay Keasling, Berkeley Lab's Associate Director for Bioscience and the CEO of DOE's Joint BioEnergy Institute (JBEI), explains how special strains of microbes can convert the biomass of non-food crops and agricultural waste into fuels for cars, trucks and jet planes. Keasling's research team at JBEI has developed E.coli that can digest switchgrass and convert the plant sugars into gasoline, diesel or jet fuel, not unlike the process by which beer is brewed.

When faced with life-or-death situations, bacteria -- and maybe even human cells -- use an extremely sophisticated version of "game theory" to consider their options and decide upon the best course of action.

Few sneezing studies have been done since then, but the number of recognized types abnormal sternutators has multiplied. There are people who experience snatiation; sneezing fits after a big meal. At least one person has noted that she sneezes when she eats over seventy-percent cacao chocolate. One woman sneezed when she thought about her loved ones. A more titillating response comes from a host of people who sneeze whenever they have sexual thoughts or directly after they have sex.

Microbes born on Earth are already pre-adapted for journeying through space, living in space, and not just surviving but flourishing in radioactive environments where they are continually exposed to radiation by ions similar to what might be...
