    I was a very lucky girl.Many girls didn't know they could take part in or even be good at sports,but I never needed to be told that because I grew up with my grandmother who was a great Olympian.Even today,many girls need that extra nod in sports,but where can they get it?

    How fit are your teeth? Are you lazy about brushing them? Never fear: An inventor is on the case. An electric toothbrush senses how long and how well you brush and it lets you track your performance on your phone.

    The Kolibree toothbrush was exhibited at the International Consumer Electronics Show in Las Vegas this week. It senses how it is moved and can send the information to an Android phone or iPhone via a Bluetooth wireless connection.

    The toothbrush will be able to teach you to brush right (don't forget the insides of the teeth!) and make sure you're brushing long enough. “It's kind of like having a dentist actually watch your brushing on a day-to-day basis,” says Thomas Serval, the French inventor.

    The toothbrush will also be able to talk to other applications on your phone, so developers could, for example, create a game controlled by your toothbrush. You could score points for beating monsters among your teeth. “We try to make it smart and fun,” Serval says.

    Serval says he was inspired by his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They said “yes,” but Serval would find their toothbrush heads dry. He decided he needed a brush that really told him how well his children brushed.

    The company says the Kolibree will go on sale this summer, from $99 to $199, and the U.S. is the first target market.

    A study found wireless signals are able to pass through bags and suitcases to judge the sizes of dangerous metal objects and identify them." These items could include weapons, chemicals, laptops and batteries for bombs, "the research team said on Tuesday.

    Research suggested that Wi-Fi can now be used to estimate the volume of liquids such as water, acid, alcohol and other chemicals for explosive material. The study led by researchers at the Wireless Information Network Laboratory (WINLAB) in the School. of Engineering showed a wireless device with two to three antennas(天线)that could be fitted in existing Wi-Fi networks.

    The detection system analyzes what happens when wireless signals go through and bounce off objects or materials. The approach, which the paper states, works by separating the wireless interference(干扰)caused by two factors of objects-the material and shape." Most dangerous objects such as weapons are usually metal or liquid, which have significant interference," researchers said.

    When it was tested on a backpack, the accuracy rate topped 95 percent. "But the accuracy dropped to about 90 percent when objects inside bags are wrapped. And the tech could save lives if used in museums, stadiums, theme parks or schools," the team said, noting its design can inspect bags or luggage without being an exposure to privacy.

    It uses channel state information (CSI) that is readily available in low-cost Wi-Fi devices." This could have a great impact on protecting the public from dangerous objects," said Yingying Chen, a co-author of the study," There's a growing need for that now. In large public areas, it's hard to set up expensive screening equipment like what's in airports. Manpower is always needed to check bags and we want to develop a method to try to reduce manpower.”

    The peer-reviewed study, which recently won a best paper award at the 2018 IEEE Conference on Communications and Network Security, is now published online." Future work will continue to focus on ameliorating the accuracy of identifying objects and imaging shapes and volumes," researchers said.

    What are two things that make humans different from animals? One is language, and the other is music. It is true that some animals can sing (and many birds sing. better than a lot of people). However, the songs of animals, such as birds and whales, are very limited. It is also true that humans, not animals, have developed musical instruments.

    Music is strange stuff. It is clearly different from language. However, people can use music to communicate things—especially their emotions. When music is combined with speech in a song, it is a very powerful form of communication.

    If music is truly different from speech, then we should process music and language in different parts of the brain. The scientific evidence suggests that this is true. Sometimes people who suffer brain damage lose their ability to process language. However, they don't automatically lose their musical abilities. For example, Vissarion Shebalin, a Russian composer, had a stroke in 1953. It injured the left side of his brain. He could no longer speak or understand speech. He could, however, still compose music until his death ten years later. On the other hand, sometimes strokes cause people to lose their musical ability, but they can still speak and understand speech.

    Why does music have such a strong effect on us? That is a harder question to answer. Geoffrey Miller, a researcher at University College, London, thinks that music and love have a strong connection. Music requires special talent, practice, and physical ability. That's why it may be a way of showing your fitness to be someone's mate. For example, singing in tune or playing a musical instrument requires fine muscular control. You also need a good memory to remember the notes. And playing or singing those notes correctly suggests that your hearing is in excellent condition. Finally, when a man sings to the woman he loves, it may be a way of showing off.

    However, Miller's theory still doesn't explain why certain combinations of sounds influence our emotions so deeply. For scientists, this is clearly an area that needs further research of sounds influence our emotions so deeply. For scientists, this is clearly an area that needs further research.

Lebanese filmmaker Nadine Labaki has become the first female artist in the Arab world to be nominated (提名)for an Academy Award, or Oscar.

Labaki directed the film Capernaum, a film about a Syrian refugee (难民) boy and a Kenyan baby who live without parents on the streets of Beirut. It was nominated for best foreign language film.

Labaki wil1 be one of the few female directors to compete for an Oscar this year. She told the Associated press "I wish there were a lot more women filmmakers this year represented, nominated in the Oscars. But I am sure in a few years we won't be having this problem anymore."

Unlike in the West, women filmmakers are industry leaders in Lebanon.

Capernaum received a 15-minute standing ovation (热烈欢迎) at this year's Cannes Film Festival. It won the Jury Prize—the third-highest award given at Cannes.

The United Nations has publicly praised the film. Lebanon's Foreign Minister said.

Capernaum put a Lebanese touch on the international film industry.

The Oscar nomination of Capernaum is the second for Lebanon in two years in the film group. It demonstrates the country's rising star power.

Labaki called making the movie a life-changing experience. She said Capernaum helps humanize the real struggles of refugees only briefly talked about in the news.

We can't help but acknowledge that there is a fear of refugees in general around the world and there are these walls we are building, and this fear that keeps growing," Labaki said.

Capernaum will compete against four other films for the Oscar, including awards season favorite Roma. Directed by Mexico's Alfonso Cuaron, it earned 10 Oscar nominations, including for best picture.
