After an anaphylactic reaction due to an unknown food, I finally had allergy testing today and it showed I was only allergic to venom (I’d had an episode due to yellow jackets once a couple of years ago). However, I had an outrageous reaction to the positive control histamine. For the intradermal test, the spot on my arm looked like a quarter with the thickness of a nickel was trying to push its way out of my arm and the lab tech/nurse said the redness was unmeasurable, and would have to be noted as the maximum of 45 rather than the three or so inches it truly was. I asked a lot of questions and she said I basically was allergic to myself by being allergic to the chemical histamine that your body produces. Basically, we’d found our answer, she said. When I mentioned it appeared I was allergic to histamine to the doctor, she said everyone is supposed to react to the histamine. And that was that.

There have been four successful robotically operated Mars rovers. The Jet Propulsion Laboratory managed the Mars Pathfinder mission and its now inactive Sojourner rover. It currently manages the Mars Exploration Rover mission's active Opportunity rover and inactive Spirit , and, as part of the Mars Science Laboratory mission, the Curiosity rover. On January 24, 2016 NASA reported that current studies on Mars by the Curiosity and Opportunity rovers will now be searching for evidence of ancient life, including a biosphere based on autotrophic , chemotrophic , and/or chemolithoautotrophic microorganisms , as well as ancient water, including fluvio-lacustrine environments ( plains related to ancient rivers or lakes ) that may have been habitable . [1] [2] [3] [4] The search for evidence of habitability , taphonomy (related to fossils ), and organic carbon on Mars is now a primary NASA objective. [1]
