In the journal Science, researchers report on a map of the genetic code of bacteria that live in cow stomachs. Why? Well, a cow’s rumen, or forestomach, may be the world’s best reactor for turning grass into gas—all thanks to trillions of bacteria, working tirelessly to produce enzymes that break down plant fiber. Turning plant material into methane, or natural gas, is exactly what scientists would like to do more efficiently, so we can grow more fuel and drill for less of it. The new research found 30,000 genes with the potential to improve biofuel production.

Also in the journal Science, researchers report that the anticancer drug Taxol may be useful in treating spinal cord injury. In laboratory rats, researchers showed that taxol reduced scarring and stimulated the growth of nerve tissue. I’m Bob Hirshon for AAAS, the Science Society.
