Bacteria survive everywhere. Under the sea, in the air, even in some of the hottest environments on Earth.
How are microbes seemingly so smart? Bacteria don't just react to changes in their surroundings, say Princeton University researchers, they anticipate and prepare for them. The findings, reported in the June 6 issue of Science, challenge the prevailing notion that only organisms with complex nervous systems have this ability.
"What we have found is the first evidence that bacteria can use sensed cues from their environment to infer future events," says Saeed Tavazoie, an associate professor in the department of Molecular Biology, who conducted the study along with graduate student Ilias Tagkopoulos and post-doctoral researcher Yir-Chung Liu.
