Micro-Organisms Can “Predict” Enviro Changes, Proving Basic Assumptions Wrong

Using two different model organisms–the E. coli bacterium and the single-celled yeast–scientist have begun unraveling a puzzling behavior of many micro-organisms: the ability to “predict” a change in environmental conditions.

It has been assumed for most of the history of micro-biological science that such micro-organisms are purely “reflexive”; they simply respond and adapt to external stimuli (such as exposure to chemicals, heat stress, or drugs). But research over he past 2 years by two different scientific teams (a Princeton team lead by Saeed Tavazoie, and, a team from the Weizmann Institute in Israel) is shaking up present understanding and over-turning basic assumptions.

Man-Made Bacteria Produces a Fuel That’s Better Than Gas

Researchers reported Monday that they have re-engineered a common bacteria to produce complex and energy-dense alcohols similar to the hydrocarbon compounds found in fuels such as gasoline. This is the first time these types of alcohols have been synthesized by bacteria (man-made or otherwise) in the lab.

E. coli is normally found in the guts of most warm-blooded animals (yes, even yours) and if you’ve had an encounter with it that you remember, chances are you spent the weekend on the toilet wishing you were dead. Yet, while it’s true that some strains of e. coli can cause food poisoning in humans, most are actually quite harmless.
