A Fishy Spy To learn about ocean animals, scientists need to get a close look. But noisy submarines sometimes scare the animals away. So scientists have invented a robot fish spy. The robot is called SoFi, short for Soft Robotic Fish. It has a rubber body and a camera in the middle of its face. It waves its tail to swim, just like a real fish. A diver nearby steers the robot with a waterproofed video game controller. As it swims around, the robot snaps photos and video of the sea life around it. In tests, SoFi swam up to 60 feet (18 m) deep. Best of all, it’s so quiet that it doesn’t scare the real fish away. Cracking the Case of Knuckle Cracks Some people think it’s satisfying to give their knuckles a…

claire’s other leg

When Claire Williams goes to the beach, she spreads out her towel. She takes off her shoes, takes off her beach wrap, puts on her swim cap and goggles, and finally, she takes off her leg. Then she hops down the beach and jumps into the water. You can bet when she takes her leg off and hops to the water, people stop and stare. It’s not every day that you see someone with a prosthetic leg. It’s even more unusual to see her take it off. But to Claire, it’s no odder than taking off her shoes. Different Legs Claire was born with a left leg much smaller than her right leg. This means that she needs a prosthetic leg to help her walk. Claire got her first prosthetic leg when she was…

How did you think of your prosthetic when you were little? Did your legs have names? My prosthetic was more like a pair of eyeglasses. I needed it to get around and felt a bit undressed when I wasn’t wearing it. I liked hopping around on one leg when I was little and light. But it was tiring. I needed my leg, so I accepted it as part of me. I never had names for my prosthetic legs, though I did call my stump “Stumpy.” Did kids ever tease you? No one teased me that I remember. My trouble was more doubting myself. It helped when my parents told me about a runner who had the exact same disability as me. Also, I did a lot of para-swimming, which is swimming with others…

a new tail for winter

Winter’s life started out unlucky. When she was just two months old, she got tangled in the ropes of a crab trap in Florida. A fisherman heard her cries. Rescuers cut her free. They took her to the Clearwater Marine Aquarium. But the little dolphin was badly injured. The ropes had cut off blood flow to her tail. It got infected, and doctors could not save it. But Winter is strong. She recovered. And she taught herself a new way to swim! Normally, dolphins move their tails up and down. Winter learned to swim more like a fish. She waggled her body from side to side. Newspapers and TV stations ran stories about the plucky tailless dolphin. Winter became famous. Winter could get around by sideways swimming. But it was not very good…

building bionic bodies

In ancient Egypt, a woman missing her big toe replaced it with a wooden one, held on with leather. In long-ago Rome, a man walked on a leg made of bronze. For thousands of years, people who have lost a toe or arm or leg have worn replacements called prosthetics. The earliest prosthetics were often crafted from wood and leather. Wood could be carved to look like an arm or a leg, but it wasn’t always comfortable to wear. And solid wooden hands couldn’t do much. The next step was to add joints that could move a little. Fancy hands could be bent to hold a fork or pen. Legs got moving knees and ankles and curved feet. That made walking easier. Today’s prosthetics are mostly lightweight metal and plastic. Some are body-powered.…

Prosthetics have come a long way since carved wooden toes. But could we make them even better? Printing Prosthetics A 3D printer works by spraying out thin layers of melted plastic to build up a solid object. They work from computer designs. 3D printers are already used to make some prosthetics. They can print parts measured to fit each user exactly. A project called e-Nable 3D prints prosthetic hands for growing kids and others who don’t want expensive robotic hands. Designs are shared on the internet. They can be modified for a perfect fit. Volunteers print out the parts and assemble the hands, adding strings to move the fingers. These hands are inexpensive and allow the users to grasp objects like cups and pencils. Printing Living Parts Modern 3D printers can print objects from metal,…
