2 . Today, plastic is used in almost everything, from shopping bags and bottles to chairs and cars. Plastic has conquered the world. But do you know how it was first made?
The first man-made plastic was created by Alexander Parkes, who introduced it at the 1862 Great International Exhibition in London. It was called Parkesine, and it was made from plant materials. Once heated, it could be molded, and it held its shape when cooled. Also, it could be made colored or transparent. However, it was too expensive to produce for common use.
In the 19th century, billiards(a game played on a cloth-covered table)was so popular that a lot of elephants were being killed for their ivory, which was used to make billiard balls. So, people tried to find a substitute. A U.S. billiard ball company offered a prize of S10, 000 to the person who could design the best substitute for natural ivory. In 1866, Joh
Wesley Hyatt created Celluloid while trying to win the prize. Although he failed to win, Celluloid was later used to make many products, including false teeth, piano keys, and ping pong balls.
In 1909, Leo Backeland created Bakelite. Made entirely of artificial materials, it was the first true plastic. It was inexpensive, and it kept its shape when heated. Soon, it was being used in many things, including electrical products and jewelry. Since then, many other plastics have been developed.
Today, most plastics are produced from non-natural materials made from petroleum. They are light, flexible, strong. and cheap. Despite all these advantages, there is one problem: plastic waste breaks down slowly and toxic chemicals can leak from it. Therefore, people are trying to develop less harmful plastics.

3 . Sharks may be able to smell blood from miles away, but they probably don't know how red it is. It is likely that they only see the world in black and white according to a study that is the first to look into sharks’ visual systems.
A team at the University of Western Australia studied the visual systems of many different species of sharks and what they have found is diversity in eye design that mirrors the ecological and behavioral diversity of the shark species. The team looked at the retinal cells of 17 species of sharks caught from Queensland and Western Australia and found out that the cells are responsible for sharks’ color blindness.
According to the study, these animals are color-blind due to the light receptors they have got in their eyes. There are two main types of light-sensitive ceils to allow animals to see: rod cells help measure brightness because they are highly sensitive to light and allow night vision but cannot tell colors apart, while various types of cone cells help distinguish colors. They looked at the structure of sharks' rod and cone cells in the retina. Human eyes come with red, green and blue cone variations, while sharks appear to have just one kind of cone cell.
The study suggests that contrast against the background, rather than color itself, might be more important for object detection by sharks. Costumes that camouflage swimmers’ bodies in sea water are less likely to draw a shark’s attention than ones with bright, solid colors that emphasize their outline. “It’s the high contrast against the water rather than the color itself which is probably attractive to sharks,” said Professor Nathan Hart who led the study.

4 . “This material is called xiangyunsha,” said Song Fei, while she introduced a traditional cheongsam(旗袍) to customers in a flagship shop. “Dyed with pure plant extracts (提取物) and unpolluted river mud, the time-honored silk cloth is named ‘soft gold’ in the textile (纺织的) industry.”
To everyone’s surprise, the knowledgeable Song, who has unbelievable insights into cheongsam, a body-hugging one-piece Chinese dress for women, has practiced law for 10 years in Chengdu City. In 2017, she traveled to Suzhou to learn design and handicraft skills of cheongsam and traditional costumes, becoming a cheongsam designer.
At first, Song’s family and friends were not optimistic about her choice to switch from a distinguished career to an artistic field. Knowing little about clothing, Song met with a huge challenge. “The pain was unthinkable, but since I had chosen that profession, I had to stick to it. I want a career that I truly enjoy,” said Song.
Song returned to Chengdu with new skills and creative passion in 2019 and founded her design brand. “To be honest, compared with my previous job, this one is harder and leaves me with much greater financial pressure. But my sense of satisfaction is beyond comparison when my works are recognized and appreciated,” said Song.
“Traditional cheongsams are one-piece tailored dresses of Chinese origin that require making with natural materials by hand. However, modern cheongsams are often made with artificial materials and produced by machine,” Song said. “In the face of rapid social and economic changes, traditional cheongsams are receiving less attention due to the popularity of mass-produced cheongsams.”
To save the beauty of traditional culture, Song wants to blend people’s daily lives with time-honored handicrafts, believing that traditional culture should not be the zone of museums. She aims to pass on traditional Chinese culture, which is a meaningful type of work with social responsibilities.

C.Unthinkable pain from the former job. | D.Love for traditional costumes. |
