There are about 3, 000 dolphins living in ocean parks around the world. People love watching them. But do they miss their home? The dolphin in this picture might be able to help them return to the ocean.

A US company built a life — like robotic dolphin. It acts robotic dolphin and sounds like a real dolphin. It can swim for up to 10 hours on a single charge(充电). During tests, people can hardly tell the dolphin is a robot and not real.

The company is now bringing these robotic dolphins to the public. It hopes these dolphins will take the place of real dolphins in ocean parks. Besides dolphins, the company wants to create Great White Sharks and some other animals for ocean parks.

In fact, people who want to protect animals are talking more about the influence of keeping wild animals in parks. The animals have to perform(表演) for visitors many times a day, as well as go through training programs. People around the world are doing more to protect wild animals. Parks and circuses(马戏团) in 20 European countries cannot have wild animal shows anymore. Ocean parks in France can no longer have dolphin shows as of Sep 29. Animal rights groups say the move is “a historical victory”.

Getting tested for COVID-19 could soon be a lot more fun for children across the world, thanks to a new Australian-made testing device (设备), which is invented by Rhinoswab Junior.

It was found that almost three-quarters of parents worried that the old testing way might be painful or uncomfortable for their child, and 30% said these worries were very likely to stop them from taking their child to have a test.

“We know each person, whether a child or an adult, will take more COVID-19 tests when new variants (变种) appear,” Dr. Shidan Tosif said.

Because of the above two reasons, we needed to develop a child-friendly testing device. The new device comes in different kinds of colors and shapes such as moustaches (八字胡) and cat noses and so on. And it will sit at the bottom of the nose. It is much more comfortable than the old testing method, which takes a sample (样本) from deep at the back of the throat and nose.

The new device will be tested at Melbourne’s Royal Children’s Hospital (RCH) over the coming weeks with further study. It’s reported that about 250 children aged 4 to 18 will try the device from 30 to 50 days.

“The new device is likely to turn a bad experience into an interesting one for children,” Dr. Tosif said.
