      A sealed keyboard cannot be sterilized unless you autoclave it. It can be sanitized, which means removing something like 99.999% of microorganisms, but it is not sterile in the sense that there is no remaining life whatsoever. No chemical agent can kill 100% of microorganisms (maybe sulfuric or hydrochloric acid at nearly 100%, but only after a long exposure period, and it would eat away the material you were trying to sterilize). Only heat (and radiation) can truly sterilize.

    I don't think there's much that can survive being blasted by steam from a boiling ho.

  44. Allergies and the Immune System by s-orbital · · Score: 3, Interesting

    You are correct about pathogens and immunity, however allergies are quite different than pathogens. The immune system fights pathogens, however the immune system is what causes allergies. They are an overreaction to foreign sustances entering the body.

    Growing up around allergens often causes allergies. The body, having been genetically predisposed to certain allergies will cause the immune system to attack allergens that it comes into contact with.

    Allergies are caused by the immune system, rather than prevented by it. Thus, it is better for children not to be exposed to possible allergens until later in childhood.

    It should be noted that it's not the water that kills devices, it's the water shorting out contacts that kills it.

    This is not so true. I am a laptop repair technician and have had to service numerous spilled-on laptops.

    Normally what seems to leave a laptop in a non-functioning state is the corrision of surface-mount components on the system board.

    Also, water can not short out electrical devices. IIRC pure water itself does not conduct electricity. It is the impurities in the water that cause it to.
