Sun Xun: Time Spy

Chinese artist Sun Xun uses woodblock (木板) printing, a centuries old method to change the 215 century medium of film. In Time Spy, Sun Xun has created a 3D world that walks freely across time and cultures that draws its inspiration from both Eastern and Western art, history, myth (神话), especially imagination.

To produce Time Spy, the artist and his team cut more than 10,000 woodblocks to make beautiful patterns, and then looked at every part carefully to create the cartoon. The choices of the woodblocks that were used to create the film will be shown publicly in the exhibition.

Thomas Edison, inventor of such items as the phonograph (留声机) and the world's first practical light bulb, is known around the world. But another lesser-known figure is owed his share of credit — Edison's competitor, Nikola Tesla. It took the work of both men to make possible a world that runs on electric power; however, their names were not always shared.

Edison, a self-made American inventor, built his name as a successful businessman.Tesla, a well-educated Serbian immigrant, was a tireless thinker. In 1882, Tesla got a job in the Paris branch of Continental Edison Company. Soon, his obvious skill won him a position at the Edison Machine Works in the United States, where the goal was to bring electricity to all of New York City. But Edison and Tesla had different ideas about how to make that goal a reality.

Edison worked mainly with direct current (DC) power. Although DC would prove useful in the decades to come, it was only effective at the time for powering things that were about a mile or less from the power source. However, alternating current (AC) power-supported by Tesla allowed electricity to be carried over long distances through power lines.

Soon the battle between the two was on. Edison proposed that several small DC-based power plants could be constructed to power different parts of a city, but this was impractical. Desperate to succeed, Edison attempted to show that DC power “was safe”— he even electrocuted (电死) an elephant to show the “dangers” of AC. In the end, however, it was practical, inexpensive AC that won the battle. By 1896, even Edison's own company had adopted AC.

Tesla succeeded, but Edison, whose self-branded companies won him over a thousand patents, is the more well-known of the two. Regardless, each inventor had a big hand in shaping the way we live.

Remember when your mom told you not to eat too many candy bars or sweets because they can cause tooth decay (蛀牙)? However, it turns out that chocolate can be more salutary to your teeth than you might expect. Recent studies show that chocolate can effectively fight against tooth decay, as if we need another excuse to eat chocolate.

Chocolate offers protection like fluoride, a main ingredient in most household toothpastes. Not only does chocolate protect our teeth, but it can do so very effectively. Studies show that chocolate has compounds that provide strong protection for teeth. One of the compounds in chocolate, CBH, is shown to protect even more effectively than fluoride.

Tooth decay happens when bacteria work to turn sugar into acids in our mouth. This is why eating foods with high sugar content can lead to more tooth decay. The compounds in chocolate, however, are anti-bacteria and can fight against bacteria in your mouth. The CBH compound in particular also works to strengthen tooth enamel (牙釉质), and protects against tooth decay.

Does this mean you can cat as much chocolate as you want without worrying about your teeth? It depends on the types of chocolate that you like. The protective effect of chocolate is most effective when you chew on cocoa beans. Of course, this option is not very appealing to; most people. A more tasty option is to choose dark chocolate with little sugar content, ideally no more than 6 to 8 grams per serving. For other types of chocolate with higher sugar content, the effect will be lessened. However, because of the protective compounds, it is still better for your teeth than other sweets and desserts containing the same amount of sugar.

A roadside system that detects if a mobile phone is in use in a passing vehicle is being tested in the UK first. Despite being unable to tell whether the driver is using the phone, it is hoped that it will act as a warning to people who make calls behind the wheel. The technology picks up the phone signal in the vehicle and activates a roadside warning sign of a mobile phone with a red line through it.

The system cannot tell the difference between a driver and a passenger on a bus, but to some degree it can warn drivers that they can be detected using their phones. Using a directional antenna (天线)，the detector picks up radio waves produced by a phone handset, and measures the signal strength and length of them. When a signal is detected of duration (持续时间) long enough and signal strength strong enough to set off the system, the detector activates the warning sign. The detector is able to distinguish Bluetooth connections or hands-free devices which, when picked up, will prevent the activation.

While this new system is no replacement for a police officer catching someone in the act, it could be enough to make some drivers think twice- and that has to be a positive step forward. However, just as technology has enabled the problem of drivers using mobile phones illegally, it can also be a big part of the solution in getting people to stop. Statistics from the devices will be shared with Norfolk Police, the county council said. The council said that enabling the system to record specific number plates could be a "future development".

Using a mobile phone at the wheel is one of the four road crimes which can have horrible consequences if it causes a deadly or serious car crash. Law enforcement (执行) technology has been falling behind for a decade and not made any easier by motor producers that encourage users to plug in their phones even before driving.
