![]() ![]() Parker’s lab works on creating artificial models of human heart tissues for regenerating organs and testing drugs, and the team built the medusoid as a way of understanding the “fundamental laws of muscular pumps”. The project is described today in Nature Biotechnology. Genetically, this thing is a rat,” says Kit Parker, a biophysicist at Harvard University in Cambridge, Massachusetts, who led the work. “Morphologically, we’ve built a jellyfish. When placed in an electric field, it pulses and swims exactly like its living counterpart. The synthetic creature, dubbed a medusoid, looks like a flower with eight petals. Genetically, this thing is a rat,” said Kit Parker, the researcher who led this project.Ī jellyfish made of silicone and rat heart cells 'swims' in water when subjected to an electric fieldīioengineers have made an artificial jellyfish using silicone and muscle cells from a rat’s heart. He rat muscle contacts when an electric field is applied across the structure, and then the elastic silicone pulls the jellyfish back to its original shape. As you can see from the following video, when placed between two electrodes in water, this synthetic structure can swim exactly like its living counterpart. Harvard bioengineers have made an artificial jellyfish by growing a single layer of rat heart muscle on a patterned sheet of polydimethylsiloxane. ![]() They had a high aluminium content, long term consumption of which can damage bones and nerves, and lead to memory loss and mental decline. Jellyfish are a popular appetiser in China, known for its crisp but fleshy texture.įake "jellyfish", made from chemicals, was first found at a food market in Huzhou, in the coastal province of Zhejiang, the local government said on its website. The marine animal is a popular appetiser in China, known for its crisp but fleshy texture, often shredded and pickled in salt, vinegar and a little sugar.Ĭlear, crunchy and counterfeit: China's fake jellyfish While a real alive jellyfish looks like this, what the China police found in the market was fake "jellyfish", made from chemicals.Ī tonne of man-made "jellyfish" has been seized by China's police, adding a new ingredient to the country's long recipe of fake foods. ![]()
