The Invention of the World Wide Web
Sir Tim Berners-Lee, an English computer scientist, invented the World Wide Web in 1989.
At first, he wanted to develop a web for scientists around the world to share information and the results of their experiments. At that time the Internet already existed. But he created a way to use the Internet to link documents to each other. Soon, he turned it into a free space for people to share knowledge, communicate, and cooperate.
The World Wide Web allows people to get all kinds of information online. The information can be images, videos, or files. It has become a significant tool for everyone, from scientists, researchers to young students as well. Scientists and researchers can share their study results, students can use it for learning or doing research online. Businesses even use it to advertise their products and to do business. Everybody can use the World Wide Web to watch videos, communicate, and attend meetings.

No More Worries about Acne
Worried about acne? Are you worried about the side effects of using drugs to cure acne? You should be. They are toxic and have side effects. They may cause burns or red skin. Soon we may have a new drug to treat it safely.
A medical student at the University of California San Diego invented a new way to cure acne. It treats acne effectively and keeps your skin clean.
The new technique uses nano-bomb technology and natural ingredients. These ingredients are from coconut oil, palm oil, human milk, cow's milk, and goat's milk. These nano-bombs find the bacteria causing acne then they attack and kill the bacteria.
Robots with the Sense of Touch
Guess what? We will soon have robots with the sense of touch. We already have smart robots that can dance, smile, and teach different subjects. But now scientists are developing robots with skin that can sense. These new robots will have skin on their fingers made from thin pieces of rubber. The skin will help robots sense because it will be very much like human skin. Scientists said that these robots would be able to sense pressure and temperature.
