    CAPE CANAVERAL, Florida (AP) -- Hundreds of worms from a science experiment aboard the space shuttle Columbia have been found alive in the wreckage, NASA said Wednesday.

    The worms, known as C. elegans, were found in debris in Texas several weeks ago. Technicians sorting through the debris at Kennedy Space Center in Florida didn't open the containers of worms and dead moss cells until this week.

    All seven astronauts were killed when the shuttle disintegrated over Texas on February 1. Columbia contained almost 60 scientific investigations.

    "To my knowledge, these are the only live experiments that have been located and identified," said Bruce Buckingham, a NASA spokesman at the Kennedy Space Center.

    The worms and moss were in the same nine-pound locker located in the mid-deck of the space shuttle. The worms were placed in six canisters, each holding eight petri dishes.

    The worms, which are about the size of the tip of a pencil, were part of an experiment testing a new synthetic nutrient solution. The worms, which have a life cycle of between seven and 10 days, were four or five generations removed from the original worms placed on Columbia in January.

    The C. elegans are primitive organisms that share many biological characteristics of humans. In 1999, C. elegans became the first multicellular organism to have the sequencing of its genome completed.

    C. elegans have two sexes: males and hermaphrodites, which are females that produce sperm. A hermaphrodite worm can self-fertilize for the first 300 or so eggs but later usually prefers to accept sperm from males to produce a larger number of offspring.

    The experiment was put together by researchers at the NASA Ames Research Center in California.

    The moss, known as Ceratodon, was used to study how gravity affects cell organization. During Columbia's flight, shuttle commander Rick Husband sprayed the moss with a chemical that destroyed protein fiber. He also sprayed the moss with formaldehyde to preserve it. Seven of the eight aluminum canisters holding the moss were recovered.

    Why worms?
    The C. elegans are primitive organisms that share many biological characteristics of humans.

    The experiment was put together by an Ames Research Center researcher and Dr. Fred Sack at Ohio State University.

    "The cells were surprisingly well-preserved, but we're analyzing how useful it's going to be," Sack said.

    NASA officials said they don't know if the worms will still have any scientific value since they were supposed to have been examined and unloaded from Columbia within hours of landing

    "It's pretty astonishing to get the possibility of data after all that has happened," Sack said. "We never expected it. We expected a molten mass."

      To some degree, this is a serious question, so I'll give it a serious answer: C. elegans serves as a useful model of development in multicellular animals (like us) because it's about the most primitive animal that still has basic systems like a nervous system, a digestive system, etc. It's also very tough (as this incident proves), reproduces quickly, and is easy to tinker with in the lab. IIRC, it was the first animal to have its genome completely sequenced.

      It also shows the capacity for rudimentary learning, making it of great interest to neuroscientist, since it's a lot easier to study the ~300 neurons in a typical C. elegans than the rather larger number found in more compex organisms.

      Not only is the genome mapped out, but C. elegans has been a model organism for development. A complete flow-chart-esque understanding of the division of the first egg cell down to the last of its 959 cells [wisc.edu]. Its one of the first model organisms for a complete body-plan understanding of genetic development, but knowing the genes and figuring out the genes are 2 differant matters. Hence the experiments in space [nasa.gov] trying to understand how 0 g and amazingly controled environments affect gene expression.

      Seeing as the Columbia Mission was the first *pure science* mission not having to do with Space Station construction in 2 years, I think its a great legacy for those who lost their lives that some really amazing science can come out of their work.

    About C. Elegans, quoting this site [ed.ac.uk]:
    The lifecycle takes about 3 days at 20 deg.C.
    It was only 4th or 5th generation (times 3 days) - hmmm did they find it 15 days after?

    The scientists better watch out, because we know how fast those things can mutate.

    As they state in the article, C. elegans have a life cycle of 7-10 days. As they also state in the article, the shuttle, at the end of its mission, crashed on Feb. 1. That was 89 days ago. But somehow they've only managed to go through 4-5 generations? It's a pretty simple calculation.

    More interesting (like CNN hasn't ever had a problem with pretty obvious facts) however is the survival. If we were talking about fungi or bacteria, organisms which are able to enter a dormant/stationary phase of the life cycle, it wouldn't be too surprising that they could survive. But C. elegans just have a pretty basic (egg-->larva-->adult) life cycle so they don't have a mechanism for surviving extreme situations (like a flaming fireball smashing into earth).

    One of the great things about C. elegans is that they're easy to mutagenize and determine which genes give rise to characteristics such as resistance to UV/ionizing radiation, long life, ability to consume large volumes of alcohol, etc. I hope that some of these super space worms get into the hands of folks like Leon Avery [swmed.edu] or Tim Schedl [wustl.edu] so they can figure out what helped these guys survive.
    • It's a plot, I tell you! It's all a plot! The C. elegans are going to take over the world!!!!!!!!!!!!!!!!!!!!!!!

      I can't believe we're going to be ruled by microscopic, invertebrate worms!!

      Not entirely true. Under ideal conditions the life cycle is egg-->L1 larva-->L2 larva-->L3 larva-->L4 larva--L5 adult but if conditions are not so good (overcrowding, lack of food etc.) Caenorhabditis can turn into something called a dauer larva [missouri.edu] which doesn't feed, doesn't move around much, and can survive for much longer.

    Seriously, this is a pretty interesting story from a scientific standpoint. Can there possibly be a more extreme barrier to survival than this?

    Of course, the conspiricist would wonder about the safety of all the other experimental residue that they were carrying. That's not to suggest that everything that goes up should be independently reentry-proof, but I wonder how well NASA could identify the parts of the vehicle

    It's not the fall from 200Km that's the problem. Like any skydiver you will quickly reach about 120mph and stay at that speed. Even a human body would be mostly recognisable after it hit the ground. People have survived falls (sans parachute) from 20,000ft when they were lucky enough to hit trees or deep snow.

    The real problem arises when you need to reduce your orbital velocity from 8Km/s to zero. To do that you need to get rid of about 32GJ/Kg, which over a 10 minute reentry is about 50MW/Kg.

    It pays to be small and very light!

    Yeah, one notable absence in the list of similarities being "Tendency to melt/dissolve upon reentry."

    Like what? Needing air and water and such, or is there any real similarities?
