  1. I think the episode of Jesus and the money changers has some historical validity at least. Archaeological and written evidence of money exchanging at least occurring there.

     

    I can't help but wish that ancient people would have left us better records. Our own descendents are probably going to be deluged in contrast.

  2. There's material on the subject on Wikipedia...

     

     

    • Radiation – tardigrades can withstand 1,000 times more radiation than other animals,[33] median lethal doses of 5,000 Gy (of gamma rays) and 6,200 Gy (of heavy ions) in hydrated animals (5 to 10 Gy could be fatal to a human).[34] The only explanation found in earlier experiments for this ability was that their lowered water state provides fewer reactants for the ionizing radiation.[35] However, subsequent research found that tardigrades, when hydrated, still remain highly resistant to shortwave UV radiation in comparison to other animals, and that one factor for this is their ability to efficiently repair damage to their DNA resulting from that exposure.[36]

     

    Tardigrades are one of the few groups of species that are capable of reversibly suspending their metabolism and going into a state of cryptobiosis. Several species regularly survive in a dehydrated state for nearly 10 years. Depending on the environment, they may enter this state via anhydrobiosis, cryobiosis, osmobiosis, or anoxybiosis. While in this state, their metabolism lowers to less than 0.01% of normal and their water content can drop to 1% of normal. Their ability to remain desiccated for such a long period is largely dependent on the high levels of the nonreducing sugar trehalose, which protects their membranes. In this cryptobiotic state, the tardigrade is known as a tun.[25]

    Assorted bacteria do even better. Deinococcus radiodurans is probably the best known.

     

    Evolution sometimes manages to outdo itself. It goes for one thing and ends up with a happy fringe benefit useful when a new species decides to start irradiating their food.

  3. @Enthalpy: Did you have a webshield running? My own AV(Avast) seems to think that the first page is infected(html:Script-inf). Other scanners are not reporting anything though. In any case it may have blocked page access on those grounds.

  4. The two I know from local elections, Rubio and Jeb weren't too out there, though personally I still disagree with a number of their positions.

     

    Since about the 80's there has been a general trend for presidents to be reelected to a second term.

    Trend would probably go back further if external factors hadn't impacted events(deaths, assassination, scandal). At the 4 year midpoint though, better candidates have a rational reason to hold off on running. Obviously this could(and probably does) result in a self-fulfilling prophesy... At any rate we should see better Republican candidates during the 2016 election. The race is really going to depend on how the Democrats play things.

  5.  

    Can you give a better definition for zero?

     

     

    There is no single denominator of zero.

     

    ie. 0/n = 0

     

    n is undefined or to put it another way it equals everything and anything simultaneously, except for zero.

     

    When you divide by zero, you have to multiply by n; leaving you with an undefined result.

  6. Hi,

     

    How does the evolution of plants happen?, such as how did some plants/trees/etc come about?

     

    Plants came about from a photosynthetic bacteria taking up residence inside one of our distant relatives. Just went from there. Cell walls are probably the best known adaption but there are a host of different adaptations out there.

     

    I don't know going forward what will happen. I know from some of the Mars testing, plants require more water in a higher concentration of CO2. So adaptations to maximize water intake/retention might be a thing. It is possible they might evolve to start retaining oxygen too, if oxygen becomes really scarce. Though I doubt it'll get that bad.

  7. IMO blimps would be the way to go. Expense could be offset by mobility and the ability to operate within a different economic-legal sphere.

     

    The World ship is probably the closest example we have today of a mobile residential community. Makes for an interesting study.
