【推荐1】Researchers at the University of Alabama in Birmingham suggest that brainwave-sensing headsets (脑电波耳机), also known as EEG headsets, need better safety after a study which shows hackers (黑客) could guess a user’s bank account passwords by monitoring (监测) his brainwaves.
Nitesh Saxena, professor in the UAB, and his team found that a person who stopped a video game and entered into a bank account while wearing an EEG headset was at a risk of having his passwords stolen by a bad software program. Saxena and his team used one EEG headset that could be bought by customers online to show how easily an ill software program could eavesdrop on a user’s brainwaves. While typing, a user’s reaction corresponds with his hand, eye and head muscle (肌肉) movements. All these movements are caught by EEG headsets.
The team asked 12 people to type passwords into a text box as if they were entering into an online account while wearing an EEG headset, in order for the software to train itself on the user’s typing and the corresponding brainwave. The team found that when a user entered passwords, the ill software program could make educated guesses about the passwords by reading the EEG data recorded. And it just increases the chance of guessing a six-letter password from one in 500,000 to one in five.
“With the growing popularity of EEG headsets and all kinds of ways they could be used, they will become part of our daily life,” Saxena said. “It is important to study the possible risks with this new technology to raise users’ awareness to the risks and develop methods of avoiding the bad attacks.” One method suggested by Saxena and his team is to make noise anytime a user types a password while wearing an EEG headset.

【推荐2】Several research groups have previously generated images from brain signals using AI models that require numerous data analysis. Now, Shinji Nishimoto and Yu Takagi at Osaka University in Japan have developed a much simpler approach by slightly adjusting Stable Diffusion, a popular text-to-image generator, allowing it to turn brain signals directly into pictures.
Shinji Nishimoto and Yu Takagi built two additional models to help make Stable Diffusion work with brain signals. The pair used data from four people obtained by using functional magnetic resonance imaging (fMRI) (功能磁共振成像技术) to scan their brains while the four were viewing 10,000 pictures.
Using around 90 percent of the brain-imaging data, the pair then trained one model to make links between fMRI data from a brain region that processes visual signals and the images that people were viewing. They used the same dataset to train the other model to form links between text descriptions of the images and fMRI data from a brain region that processes the meaning of images. After training, these two models could translate brain-imaging data into forms that were directly fed into the Stable Diffusion model. It could then reconstruct around 1000 of the images people viewed with about 80% accuracy. This level of accuracy is similar to that previously achieved in a study that analysed the same data using a much more tedious approach, which involved more time and efforts.
However, the study only tested the approach on four people. “This approach requires huge fMRI machines”, says Sikun Lin at the University of California. “In future, more practical versions of the approach could allow people to make art or change images with their imagination, or add new elements to gameplay, but it is still a long way from daily use,” she says.

【推荐3】Professor Ashok Goel of Georgia Tech developed an artificially intelligent teaching assistant to help handle the enormous number of student questions in the online class, Knowledge-Based Artificial Intelligence. This online course is a core requirement of Georgia Tech’s online Master of Science in Computer Science program. Professor Goel already had eight teaching assistants, but that wasn’t enough to deal with the overwhelming number of daily questions from students.
Many students drop out of online courses because of the lack of teaching support. When students feel isolated or confused and reach out with questions that go unanswered, their motivation to continue begins to fade. Professor Goel decided to do something to remedy (改进) his situation and his solution was to create a virtual assistant named Jill Watson, which is based on the IBM Watson platform.
Goel and his team developed several versions of Jill Watson before releasing her to the online forums. At first, the virtual assistant wasn’t too great. But Goel and his team sourced the online discussion forum to find all the 40,000 questions that had ever been asked since the class was launched. Then they began to feed Jill with the questions and answers. After some adjustments and sufficient time, Jill was able to answer the students’ questions correctly 97% of the time. The virtual assistant became so advanced and realistic that the students didn’t know she was a computer. The students, who were studying artificial intelligence, were interacting with the virtual assistant and couldn’t tell it apart from a real human being. Goel didn’t inform them about Jill’s true identity until April 26. The students were actually very positive about the experience.
The goal of Professor Goel’s virtual assistant next year is to take over answering 40% of all the questions posed by students on the online forum. The name Jill Watson will, of course, change to something else next semester. Professor Goel has a much rosier outlook on the future of artificial intelligence than, say, Elon Musk, Stephen Hawking, Bill Gates or Steve Wozniak.

【推荐2】We all have a favorite little spot to eat. Maybe it's a noodles cart or a sandwich shop. Well, it seems that you don't have to make that difficult choice now. A new Netflix documentary（纪录片）series, Street Food, aims to tell the world about all of our favorite little spots.
Released on April 26,2019, the series takes viewers through nine Asian countries and regions in search of local communities and their cuisines, from Tom Yum in Bangkok, Thailand, to snails in Ho Chi Minh City, Vietnam. Despite the series' title, Street Food is actually about people.
“At its heart, the show explores how and why some people end up selling noodles, sweets or rice on the street, and the answers aren't always easy,” wrote Zach Johnston of news website UPROXX.
Take Toyo from Osaka, Japan, as an example. He's locally famous for serving food and jokes. “He seems like the happiest man alive,” writes Calum Henderson in the New Zealand Herald, “until he talks about his father and starts crying.” Toyo learned how to cook as a child, out of necessity. His father didn't care about feeding him. Without any money, Toyo would cook weeds and leaves he found in the fields near his school. Today, Toyo has a job that he loves. What about the people who love to eat street food?
“In India, there's this Nihari stew（炖菜）,” recalled the series' creator Brian McGinn in an interview with the website Mashable. “Every morning, hundreds of people line up for this stew in this alleyway（小巷）…as everyone tries to be one of the people who are going to get some of this stew before they run out.” Moments like these can be found throughout the series, showing that street food is important to local cultures and communities. McGinn says food is a way to look at and understand people's lives. "It's not just nice food shots," Gelb told Mashable. “It's the story, the context and the character that make the food more delicious, more meaningful and more powerful.”

【推荐3】A Chinese TV play,The Long Night has enjoyed great popularity, getting a high score of 9.2/10 on Douban. Viewers all spoke highly of this drama, saying it is even better than the original work.
As TV series such as The Bad Kids, Nothing but Thirty and Horizon Tower are still popular, netizens become excited and think that domestic(国内的）dramas are worthy of being followed. The Long Night, for example, makes people realize that everything can be easily imitated and copied except the understanding and search for aesthetics(美）. Imitated or copied dramas often have no soul.
However,quite a few Chinese dramas prefer repeating or copying the content and theme in other dramas or their own ones.
Daylight Entertainment produced Ode to Joy(欢乐颂） to reveal the happiness and sadness of city beauties,receiving many positive comments.However, after the reproduction of Ode to Joy 2,All Is Well,and If There's No Tomorrow,it was criticized by professionals and audience for stereotypical(刻板的）creation:"Pile up the hopes of one hundred people onto one person the hero looks just like a live complaining post in the forum,and other characters are tools to hunt him."
Twenty Your Life On and Nothing but Thirty give the audience an impression that they are completely "coming from the trending topics and living on the trending topics". One viewer commented "I am guessing the next plays will be Forty to Know the Mandate of Heaven,Fifty to Move on,and Sixty Still Young".
Taking a closer look at the works that have earned a place in the history of Chinese drama none of them is a copy or copycat. Besides, they are too good to be followed.
Now,many Chinese dramas are noticeably turning themselves back to the right track. Hopefully,a good drama will not be followed by a group of twins or siblings.
