Current Event #4

In an article titled "Why Bacteria, But Not Humans, Can Live on Caffeine," Veronique Greenwood informs readers on scientific research about caffeine.

Veronique stated "humans don't get the energy, in the scientific sense, from caffeine." Humans can not break down the caffeine molecules far enough to get the energy. Veronique also wrote it is not "a problem for the new bacterium, Psuedomonas putida CBB5." P. putida CBB5 has the proper enzymes to break down caffeine and harvest the energy.

Greenwood stated that it may be possible "that there are some bacteria in our digestive system or elsewhere that can degrade caffeine." There may be some types of bacteria in human bodies that may allow us to get some of the energy form caffeine.

I personally have a cup of coffee every day, and I a little more energetic after drinking it.

Though scientist currently believe we do not get energy from coffee, we may one day find a way, or a bacteria, to help us get the energy from caffeine.
