Some people have a special small technology inside their body. It is like a little chip that a doctor puts under the skin. The chip has a number that tells about the person. It can have details like their name, their health, or their address. A man named Kevin Warwick from Britain put the first chip like this in his body in 1998. His chip helped him open doors without using his hands. He took the chip out after nine days. Now, you can see it in a museum in London. There is a group called NFC Forum. It began in 2004 with companies Nokia, Philips, and Sony. They work on NFC, which makes it easy for electronic things to talk to each other without wires. They set rules so that all NFC things can work together. In 2018, a company called VivoKey made a very good chip that you can put in your body. It keeps things safe. You can even use it for things like Bitcoin or to keep your passwords. Elon Musk has a company named Neuralink. They did a special show on August 28, 2020. They are also working on chips for inside the body.

There was a bird named the dodo. It could not fly. It lived on an island called Mauritius near Madagascar in the ocean. The dodo had no living family but was like the pigeon. It looked grey and had yellow feet and a colorful beak. The dodo ate fruits and lived in the woods. People saw the dodo for the first time in 1598. Sailors came and the bird went away forever because they hunted it and changed its home. The dodo was big and could not fly because it did not need to run from danger or find food. People used to think the dodo was slow, but it was good for its home.

Scientists can make a special kind of DNA in labs. This DNA has parts from different things like plants and animals put together. It's like building with blocks, but with tiny pieces that all living things have. These tiny pieces are almost the same in every living thing, but they have small differences. Scientists make this special DNA and it can be from a mix of any living things. Like taking a piece from a plant and putting it with a piece from a tiny bug. Sometimes, they make brand new pieces that no living thing has. If they put this special DNA into a living thing, it might make a new kind of protein. But it's tricky, and the living thing might not make it without help. Making this DNA is not like what usually happens in nature. It is something that scientists do with special tools in labs. It is a smart way to learn and make new things.
