We brush our teeth every day but few people know how well we’re brushing. Today, a French company has introduced an electric toothbrush, which can work wirelessly (无线地) with a smartphone.
It’s called the Kolibree toothbrush. It has different models, and will cost from $99 to $200.
Users download an app and connect via Bluetooth, and the Kolibree will record 1) the time you spent brushing teeth, 2) whether all areas of your mouth are reached, 3) whether you brush up and down instead of just side to side. Then it will send the information to a mobile phone via Bluetooth, telling you whether you have brushed in a proper way. The Kolibree app records your progress and scores your brushing way to help you improve brushing habits.
The toothbrush will also be able to talk to other apps on your phone, so developers could create a game controlled by your toothbrush. That would be very interesting.
The Kolibree toothbrush was invented by Thomas Serval. He says the idea of inventing it came from his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They always answered “yes”, but Thomas used to find their toothbrush
heads dry. He decided that a kind of brush was needed to tell him how well they brushed their teeth. Thomas says that one day, it’ll be possible to use a brushing unit with a camera. The camera can even examine holes in your teeth while you brush.

Do you look like your name? Scientists say there’s a good chance you do.
This comes from a new study published in a magazine. Researchers from Israel found that
our given names may have something to do with our facial (面部的) appearances.
Lead writer Yonat Zwebner of a university, along with her team, did eight different experiments (实验) in Israel and France. The different experiments were set up to answer two main questions:
whether people can correctly guess a person’s name based only on a photo of a face and what is behind this matching effect.
During the experiments, researchers asked students to look at photos of people’s faces and
guess each person’s name from a list of four choices. They correctly guessed the right name 38 percent of the time, which was better than the 25 percent of a random (随机的) guess.
What’s more, when the faces the students looked at came from within their own country, they were able to best match the faces to the names. French students were better at matching only French names and faces while Israeli students were better at matching only Hebrew names and Israeli faces.
Researchers believe it is possible that people change their appearances without paying attention to it, to match their names. One study especially backed up this idea, showing that a hairstyle, something that can be changed by people easily, was enough to guide others in correctly guessing their names.
“Earlier research has shown there are cultural stereotypes (偏见) carried by names, including
how someone should look. For example, people are more likely to imagine a person named Bob to have a rounder face than a person named Tim. We believe these stereotypes can, over time, influence people’s facial appearances,” Zwebner said.
The results of the experiments may even make parents think twice when choosing a name for their children.
“If a name can influence appearance, it can influence many other things. This research opens an important direction that may suggest how parents should consider better the names for their children,” said Zwebner, who recently had a baby herself.
“As parents, it was really difficult for us to name our 12-day-old daughter as we know the meanings of names.”

“The two nurses who put private locks on public-use bikes disturbed the public order,” said Liu Lin, a lawyer at Beijing Shuangli Law Firm, because it prevented other people from using the bikes.
Those who intentionally damage property(故意破坏财产)
may face a 5-day administrative detention(行政拘留), according to the Law on Public Security Administration Punishments.
Tang Ke from the publicity office of OFO, the company that owns the bikes, confirmed the news and said further investigation(调查) was underway.

has brought a greener and more convenient mode of city transportation, but the mode has also caused many problems including illegal(非法的) parking, theft and vandalism(故意破坏). Parking violations(违规) are also a common problem, followed by violation of traffic rules.
“Once users scan the app and click 'accept' when they rent (租借) the bike, they have signed an agreement with the service provider and should follow the rules.” Liu said.
