Worm grows two heads after space missionIn an extremely rare occurrence, the body plan of a planarian flatworm changed after five weeks aboard the International Space Station.
Worm becomes two-headed after space trip. It's the topic you've wanted to discuss for years, space worms. In 2015, planarium flat worms were sent aboard space axis fifth commercial resupplies services mission to the international space station. Some background unplanarium flat worms, they have the ability to renew their cells as they age or encounter damages, and regenerate all body parts. Including complex organs The point of the worm's trip was to see how healing would be affected by the organisms being subjected to microgravity and micro-geomagnetic fields. So some worms went up to the ISS for five weeks, while another set remained on Earth as a control. Some of the worms had their heads and tails removed immediately before the mission, others were sent fully intact. Most unusually. One amputated worm that went into space regenerated into a double headed specimen. That is extremely rare. The researchers say they have never observed any spontaneous occurences of double headedness in more than 18 person years. So what did the do with their new double-headed friend? The researchers removed both head on Earth. The headless middle fragment re-grew two heads, again. A third round of amputation yielded the same results. The researchers think there was a major body-plan modification in the animal. Because of a number of variables, the researchers are not able to directly link micro-gravity. Micro geomagnetic fields, or vibration of liftoff with the differences in the space worms and the earthbound worms. For more information, check out Cnet.com. I'm Iyaz Akhtar and I'll see you online.
