Why Bacteria, But Not Humans, Can Live on Caffeine

     In an article by Veronique Greenwood titled "Why Bacteria, But Not Humans, Can Live on Caffeine," Greenwood informs readers about Pseudomonas putida CBB5 and why humans can't live on caffeine.
     The article states "This doesn't seem to be a problem for the new bacterium, Pseudomonas putida CBB5..." Pseudomonas putida CBB5 can get energy from caffeine.
     "But compare the calorie count for a black coffee with a latte and it's obvious that humans don't get energy, in the scientific sense, from caffeine." Humans don't get energy from caffeine, so they wouldn't be able to live off of caffeine.
     The article also states "The specific reason caffeine isn't an energy source for us, thus, is that we don't have the gear to digest derivatives further." Humans can't digest caffeine derivatives like Pseudomonas putida CBB5 can.
     I became an active participant in my learning because I didn't know that anything could live on caffeine.

Government report on secret flying saucer program made available

     In a recent article titled "Government report on secret flying saucer program made available," the author informs readers about the government's plan to build a flying saucer.
    The article states  "...came across a 114-page document from 1956 sure to interest the tin-foil-hat crowd: a document describing a secret program by the Air Force to build a flying saucer." Why would the government want to build a flying saucer? Perhaps they feared another Roswell incident and wanted to be prepared.
     The article also states "The newly released documents, not yet posted on the website of the National Declassification Center, offer details on a Cold War-era plan to build a round vertical takeoff and landing aircraft that can only be described as a flying saucer." The government had planned on building a flying saucer, but that didn't work out.
     "The report notes a follow up plan to develop weapons suitable for the saucer..." The government wanted to build the flying saucer and make sure it worked properly, and wanted to build weapons for it.
     This article makes me think about all those movies about aliens.
