Worm Descendants From Columbia Disaster Relaunched

Posted by timothy on from the they're-delicious-in-space dept.

astroengine writes "In 2003, Space Shuttle Columbia burned up on reentry, killing all seven astronauts on board. However, from the wreckage, a sample of C. elegans worms survived. On Monday, descendants from the worms that survived the disaster were launched on board Endeavour for experiments on the space station. 'C. elegans is a common, well-studied organism used in biomedical research as a model for human development, genetics, aging and disease,' says NASA. 'The organism shares many essential biological characteristics found in human biology.'"

      I've worked with C. elegans before. It gets worse.

      They have males and hermaphrodites. The males can fertilize the hermaphrodites, but the hermaphrodites can fertilize themselves as well. This is gross, and as a guy, kind of feels like nature telling me I'm non-essential.

      In lab, the worms eat lawns of e.coli. They'll eat up all the bacteria on a petrie dish in a week. If you leave a plate of worms on ecoli and come back a month later, you'll see the worms have made balls of themselves, but are still alive. Worm biologists call that "dauer," and one was trying to explain something about it to me, but all I got out of it was the terrifying fact that even starvation can't kill them.

      Holy water does not kill C. elegans. It just makes them sparkle.

      Certain mutations cause the worms to be born without neurons. They survive, they're just "uncoordinated." Neurotoxin wouldn't be able to stop them either.

      Certain other mutations cause the "bag of worms" phenotype. Remember how I said the hermaphrodites can fertilize themselves? If the worm can fertilize the eggs but not lay them... the embryos will eat their way out. It's like Aliens.

      If you want a plate of worms all at the same age, you just soak them in bleach. One stage of development is evidently resistant. To bleach. Bleach even kills ebola. Not C. elegans.

      C. elegans also exhibit a rare phenomenon called Eutely, where an exact number of cells is produced to make each adult worm. The mapping/division of each and every one of those 959 somatic cells is well known and studied.

      Also, to inspire reasearch among more slashdotters, it is really cool to look at them up close because you can directly observe the growth/development of the organism inside the mom along the conveyor-belt-like uterus they have. Each egg along the belt is at a later stage as you progress away from the gonad. You can observe nuclear fusion between sperm/egg, 2-cell, 4-cell, 8-cell, 16-cell, blah cell (32 looks messy), morula, gastrula, etc etc.. It's really cool. In any given mother/herm you can observe several of them. You probably wont see every one from every stage in one mom, but you'll see a few... and all the way up to the living young worm that will come out, hatch from its football-egg pouch, and look just like mom (but smaller).

      If you really want to be amazed, look up the image of a C. elegans sperm. It looks like a big slice of pizza!

      The fact that males still exist despite the existence of hermaphrodites shows that they are essential. Sexual reproduction allows for recombination and greater diversity, increasing the ability of the species to adapt to new environments, diseases, or stressors and to eliminate deleterious mutations.

While male support after that point is helpful and historically beneficial (for humans) it is not absolutely necessary and could certainly be performed by other females in the community.

      It's the eggs - they have an eggshell that's more resistant to bleach than the organism. If you let it sit in bleach for an hour it'll eat through the eggshell and kill the embryo, but there's a short period of time where the adult has dissolved but the eggshells are basically intact

      This is actually two different phenotypes. Bags of worms are because the worm doesn't lay eggs if it's starving. The problem is that if they starve long enough, the eggs will hatch inside the mother, and... start crawling around and eating things. They can't get out because the worm has a strong skin, so until they're able to basically eat a hole out of the skin, they just crawl around inside

      Dauer is a completely different and even more bizzare thing - the worm develops from an embryo to an adult in ~3 days normally, and then can survive as an adult for ~2-3 weeks. Without food, though, it halts mid-way in development as a "dauer", which can live for MONTHS with absolutely no food. Then if you give it food, it resumes development normally, becomes an adult, and has perfectly normal offspring
