Passage Three

Researchers have used very small electronic devices to make jllfish (水母) stronger and faster. The scientists say they used these electronic jelly fish in the hopes of sending them to study and explore the world's seas.

A report on the experiment was published in the magazine Science Advances. The study shows jllyfish are unusual living things. They move through seawater by reducing the size of their muscles. For the experiment, the researchers put an electronic device, about 2 centimeters in length, inside a moon jelly fish, a common kind of jelly fish.

The researchers said the device caused jellyfish to move their bodies more often. They swam around three times faster than usual. Jelly fish are known to produce something from time to time when they are feeling stressed. No such action appeared during the study. "Care is taken to the jellyfish, " Dabiri explained. "The jellyfish swam the same when the electronic device was taken away after the experiment, " the researchers said

"It's very unusual and modern. It seems to happen only in the future. " said Xu, an engineer at Stanford University. "We could send these jellyfish to different areas of the sea to get signs of climate change or have a close watch on nature. "“One of the first purposes will be going deep, " added Dabiri. "Going deep is important because humans need to understand the deep seas.”

"Generally, we'd put these jllyfish at the surface, have them sw im down to increasing depths, and make them back to the surface with data. Before that the electronic devices help us see just how far we can get them to go down into the sea," Xu said.

"Jelly fish have lived on earth for over 500 million years, and over that time, their bodies have nearly remained unchanged," said Xu. "So it's interesting to find out what makes them so special in the sca and how we can learm from them. " Xu added, "We use animals with natural sw imming abilitics instcad of submarines ( 潜水艇) which might harm the env ironment. "
