Acetylene Based Life on Titan?

mindpixel writes "Astrobiology Magazine's Leslie Mullen has a fascinating interview with funky science dude David Grinspoon about the possibility that there may exist a whole new biology on Titan where the extreme cold slows normally explosive reactions to a biologically useful pace." From the article: "What's really new in our paper is that we go into the question of energy sources. If there's life there, what's it going to eat? What kind of food is there? And it turns out there's abundant food because of all this photochemistry in the upper atmosphere, where methane is being turned into other organic molecules. Some of those organic molecules are very energy-rich, and one that we consider in the paper is acetylene. We know it's being made in the atmosphere, we know it's raining down on the surface, and it's been detected at the surface with the Huygens probe. We calculated that, if acetylene is reacting with the hydrogen gas to turn it back into methane, quite a bit of energy is being released. So that's our basis for saying there is something to eat on Titan. We don't know if there are any customers, but there's something on the menu."

    RESUME / George W. Bush The White House, USA

    EDUCATION AND EXPERIENCE LAW ENFORCEMENT: I was arrested in Kennebunkport, Maine in 1976 for driving under the influence of alcohol. I pled guilty, paid a fine, and had my driver's license suspended for 30 days. My Texas driving record has been "lost" and is not available.

    MILITARY: I joined the Texas Air National Guard and went AWOL. I refused to take a drug test or answer any questions about my drug use. By joining the Texas Air National Guard, I was able to avoid combat duty in Vietnam.
    COLLEGE: I graduated from Yale University. I was a cheerleader.

    PAST WORK EXPERIENCE: I ran for U.S. Congress and lost. I began my career in the oil business in Midland, Texas in 1975. I bought an oil company, but couldn't find any oil in Texas. The company went bankrupt shortly after I sold all my stock. I bought the Texas Rangers baseball team in a sweetheart deal that took land using taxpayer money. With the help of my father and our right-wing friends in the oil industry (including Enron CEO Ken Lay), I was elected Governor of Texas.

    ACCOMPLISHMENTS AS GOVERNOR: I changed Texas pollution laws to favor power and oil companies, making Texas the most polluted state in the Union. During my tenure, Houston replaced Los Angeles as the most smog-ridden city in America. I cut taxes and bankrupted the Texas treasury to the tune of billions in borrowed money. I set the record for the most executions by any Governor in American history. With the help of my brother, the Governor of Florida, and my father's appointments to the Supreme Court, I became President after losing by over 500,000 votes.

    ACCOMPLISHMENTS AS PRESIDENT: I invaded and occupied two countries at a continuing cost of over one billion dollars per week. I spent the U.S. surplus and effectively bankrupted the U.S. Treasury. I shattered the record for the largest annual deficit in U.S. history. I set an economic record for most private bankruptcies filed in any 12-month period. I set the all-time record for the biggest drop in the history of the U.S. stock market. I am the first president in U.S. history to enter office with a criminal record. I set the all-time record for most days on vacation in any one year period. After taking-off the entire month of August, I presided over the worst security failure in U.S.history. I am supporting development of a nuclear "Tactical Bunker Buster," a WMD. In my State Of The Union Address, I lied about our reasons for attacking Iraq, then blamed the lies on our British friends. I set the record for most campaign fund-raising trips by a U.S. president. In my first year in office over 2-million Americans lost their jobs and that trend continues every month. I set the all-time record for most foreclosures in a 12-month period. I appointed more convicted criminals to administration than any president in U.S. history. I set the record for least amount of press conferences than any president since the advent of television. I presided over the biggest energy crisis in U.S. history and refused to intervene when corruption involving the oil industry was revealed. I presided over the highest gasoline prices in U.S. history. I have cut health care benefits for war veterans and support a cut in duty benefits for active duty troops and their families-in war time. I have set the all-time record for most people worldwide to simultaneously protest me in public venues (15 million people) shattering the record for protest against any person in the history of mankind. I've broken more international treaties than any president in U.S. history. I'm proud that the members of my cabinet are the richest of any administration in U.S. history. My "poorest millionaire," Condoleeza Rice, has a Chevron oil tanker named after her. I am the first president in U.S. history to order an unprovoked, pre-emptive attack and the military occupation of a sovereign nation. I did so against the will of the United Nations, the majority of U.S. citizens, and the world community. I created the Ministry of

    "It would be wrong to teach evolution in schools as though it were fact. It would also be wrong to teach the theory of universal gravitation or Newtonian Physics as fact, since they have been proven to be untrue on very small scales, or at very high velocities."

    What an odd thing to say. First of all you yourself said that evolution does happen. Anyway....

    If it's "very wrong" to teach evolution as though it was fact why is it OK to teach that some super intelligent being designed the universe? Where is your body of evidence for that?

    This is the problem with you religious fundamentalists. To you all theories are equally valid. If I claim that the universe was created when a giant turtle shit that's just as valid as a super intelligent being in the sky created it which is just as valid as evolution right?

    How come you guys don't want to teach my giant turtle shit theory though? I mean evolution is just a theory, it's not a fact and my theory is just as good as evolution or your bearded white guy in the sky theory.
