Good morning, everyone! Are you ready for that first cup of coffee? Apparently a strain of bacteria is, too. Researchers have engineered E. Coli bacteria that are "addicted" to caffeine. Why? That's a very good question. The latest creation is not a new idea. Researchers have been engineering organisms for years to feed on undesirable substances and then produce harmless ones. The concept could have major implications for cleaning up oil spills or, in this case, decontaminating wastewater.
