Millions of people suffer from motion sickness (晕动症).They have a lot of activities they fear. They often avoid doing these activities which include long-distance airplane travel, sea-trips, road-trips，even certain movies and video games. However, the French company Boarding Ring promises that it has its way to solve the problem, as long as the users are willing to wear Boarding Glasses!

Why do many people suffer from motion sickness? It is believed that the brain fails to deal with mixed signals from body parts. For example, when you are looking at your phone on a moving bus, your inner ear realizes the move but your eyes, focused on the screen, think you don’t move.

Boarding Glasses tries to ease (减轻)motion sickness by making the user’s eyes and ears transmit the same message. After the brain receives the same message, it will think you are in a moving environment. Though that sounds difficult, the science behind the glasses is surprisingly simple. The plastic frames (框架),made up of two round frames on the front and two on the side, are filled with some blue liquid. Any movement can cause the liquid to flow around the eyes. This allows the eyes to sense the move and send the correct signal to the brain.

According to Antoine Jeannin, CEO of Boarding Ring, Boarding Glasses has been tested. The CEO said that over 95 percent of the users felt better after wearing the glasses. The best part is that Boarding Glasses only has a frame» so a single pair can be worn among a group of friends, or even an entire family!

No one knows who made the first ice cream. Some people think that water ices and milk ices may have been made by the Chinese between three thousand and a thousand years ago. In that time, the dish reached India. The Indians, in turn, many have passed on the secret to the Arabs and Persians.

Marco Polo, an Italian who travelled widely in the thirteenth century, noted that he found the Chinese had long been making ices out of fruit juices and milk. From the fourteenth century on, ices became popular first in Venice and then throughout Italy.

In 1535, when Catherine de Medeicis left Italy to marry the future King Herry II of France, she took her cooks with her. They made desserts the French had never tasted before, which was ice cream.

At first ice cream was a luxury in France. Only rich people had the money to buy it. Then, in 1660, a young man from Sicily, Francisco Procopio, arrived in Paris. He opened a shop that sold ice cream at prices people could afford. Then his ice cream became more popular that other shops were opened.

About 1640, King Charles introduced ice cream to England and soon ice cream quickly became popular in England too.

Researchers from Purdue University have developed a new white paint that can reflect over 95 percent of sunlight, which can cool the surface even lower than the surrounding temperature. Painted on a building, the new paint could help cut cooling costs and energy use.

Many different reflective cooling paints have been developed over the years, but they all have their disadvantages. For the new study, the Purdue researchers developed a new method—using calcium carbonate（碳酸钙）fillers, which are much richer, cheaper, and absorb less ultraviolet（紫外线的）light. And the new reflective cooling paint can give off more sunlight—reflecting 95.5 percent of the light that strikes it. That's better than many of the other paints in development, which manage between 80 and 90 percent, although it falls short of the record holder—the Teflon coating, which reflects 98 percent of light.

The team tested the new coating outdoors over two days, and showed that under direct sun- light it remained 1. 7℃ below the surrounding temperature. In another set of tests, the researchers painted some parts of a pattern with the new paint, and others with a regular white paint of the same thickness. Using a special camera, they could see the pattern clearly, thanks to the difference in temperature between the two materials.

The team says that the new paint could not only help cool buildings, but prevent outdoor electrical systems from overheating. But to ensure that it is commercially practicable, the researchers next plan to investigate how well it lasts out in the environment.

"The cost of our paint may be comparable to other commercial paints or even lower than them," says Xiulin Ruan, an author of the study. "The key is to ensure the reliability of the paint so that it is workable in long-term outdoor applications."
