What if you arrived home to find it delicious hot meal waiting for you, prepared by your very own kitchen robot? It might sound like science fiction. but professors at the university of Tokyo  have  taken  the first steps toward making that  scenario a reality. The team recently introduced a humanoid kitchen robot that can pour and other drinks into cups and serve the m to guests. When teating is over, the robot can also wash the dishes and put them away.

    In California, another interesting kitchen robot has been developed, called Readybot. It can pick up objects and either store them in  cabinets (橱柜）or put them in the trash. It also carries a separate floor-cleaning robot that can operate by itself. Unlike the Japanese robot, Readybot just looks more like a large box with arms and wheels.

    Readybot was created by engineers and designers who established a club called the Readybot  Challlenge. They believe that in the future millions of robots will be needed in homes to perform ordinary household tasks. Readybot is just the first step in their plan to create a robot that can do jobs not  only  in  kitchens but  in other rooms of homes and in offices as well.

    Clearly there are technological difficulties to solve before robots can cook a Complete dinner, and there arc also many safety concerns (忧虑） .Not everyone (especially parents) would be comfortable with the idea of robots in their house, manipulating hot pans and sharp knives. The European Commission recently funded(资助） a project to study these concerns. According to lead researcher Professor Chris Melhuish,“ Enabling  robots to work  safely with humans is a key need for the future development of robotics.”

    An autonomous vehicle designed for making local commerce deliveries was unveiled by Nuro. The vehicle is about the height of an SW but far narrower than a typical car. The electric car features four exterior compartments (暗格) — two on each side — to hold separate deliveries. Each compartment can be tailored to a specific use, such as cooking a pizza or refrigerating a package.

    “We can use self-driving technology to deliver anything, anytime, anywhere for basically all local goods and services,” Nuro co-founder Dave Ferguson said. “Consumers used to be okay with two-week paid shipping. It became two-week free delivery, followed by one week, two days, and the same day. Now same-day delivery isn't fast enough for some customers.”

    Nuro isn't alone in building robots for local commerce deliveries. Earlier this month, Toyota, a Japanese car company, unveiled a concept vehicle that could be used for package delivery. A handful of startups — including Starship Technologies, Marble and Dispatch — are testing small robots for deliveries on sidewalks.

    Nuro's vehicle will likely face legal hurdles. Fully autonomous vehicles without a test driver aren't legal in California today, and many companies have shifted testing to states where regulators are more welcoming of autonomous vehicles, such as Arizona.

    Nuro expects to face fewer challenges because it doesn't carry passengers. Nuro's narrow size may also be helpful when navigating streets and avoiding pedestrians. The vehicle isn't equipped with any special features to communicate with pedestrians or other road users. Some companies have tested and patented solutions such as digital screens that signal the car's next move. Ferguson said his team conducted studies and found that such techniques could confuse people. Nuro believes it's better to make sure the car performs predictably, so that human drivers know what to expect from it.

    “We feel by creating this new technology that's going to enable this last mile delivery, we're going to be creating new markets and doing things that previously weren't possible,” Ferguson said. “This is not swapping out Jobs with robots. It's creating new markets. There will definitely be new employment opportunities.”

    We've all been there: in a lift, in line at the bank or on airplane, surrounded by people who are, like us, deeply focused on their smartphones or, worse, struggling with the uncomfortable silence.

    What's the problem? It's possible that we all have compromised conversational intelligence. It's more likely that none of us start a conversation because it's awkward and challenging, or we think it's annoying and unnecessary. But the next time you find yourself among strangers, consider that small talk is worth the trouble. Experts say it's an invaluable social practice that results in big benefits.

    Dismissing small talk as unimportant is easy, but we can't forget that deep relationships wouldn't even exist if it weren't for casual conversation. Small talk is the grease (润滑剂) for social communication, says Bernardo Carducci, director of the Shyness Research Institute at Indiana University Southeast. "Almost every great love story and each big business deal begins with small talk," he explains. "The key to successful small talk is learning how to connect with others, not just communicate with them."

    In a 2014 study, Elizabeth Dunn, associate professor of psychology at UBC, invited people on their way into a coffee shop. One group was asked to seek out an interaction(互动) with its waiter; the other, to speak only when necessary. The results showed that those who chatted with their server reported significantly higher positive feelings and a better coffee shop experience. "It's not that talking to the waiter is better than talking to your husband," says Dunn. "But interactions with peripheral(边缘的) members of our social network matter for our well-being also."

    Dunn believes that people who reach out to strangers feel a significantly greater sense of belonging, a bond with others. Carducci believes developing such a sense of belonging starts with small talk. "Small talk is the basis of good manners," he says.

    I have a neighbor who is a capable, fashionable, seventy-year-old, single woman. Her name is Grace. Grace was laid off from her job a little over two years ago and has been living off her savings ever since but not officially "retired". Grace called me up one day about this time last year and asked if I had a ladder. She needed to clean out her gutters (水槽) on the roof and wanted me to hold the ladder.

    She didn't want me to climb up and clean the gutters. She just wanted me to hold the ladder. As it happened I did have a ladder. I said: “The leaves are going to fall off the trees in a month, why don't we wait till they finish and do it then?” She agreed and naturally we didn't talk about it again until spring. Spring in Tennessee is wild and we talked about it over the course of three weeks in which it rained nearly every day, then I got busy and Grace went into seclusion (隐居).

    A couple of weeks ago, she told me she'd been spending too much money and decided to apply for a bar tending job at a local hotel. "Now I don't know about you all but I'd never considered what it would be like to apply for and begin a new job at the age of seventy. I'm fifty-three and the older I get, the more I think about how great it'll be if I can just get out of bed when I'm seventy." Anyway, she got the job, serving the bar and tending banquets at the hotel.

    The day when she left for her training at 6 am, I walked across the street with my ladder and cleaned out her gutters.

    A mother goat is able to pick out her own baby from its voice alone by the time the kid is just five days old.

    Researchers from University of London played kids' bleats to female goats and studied their responses. They were surprised to find that the animals were able to pick out their own kids' voices.

    “A mother and the kid rely a lot on smell to recognize one another and, in the wild, during the first week of their lives, the animals hide in grass and don't call much. It's a strategy they use to avoid enemies,” Dr Elodie Briefer, who led the research, explained to BBC News. “The mother call to the kids when she want them to come and feed, so we expected that kids would recognize the mothers' voices.” In fact, this was the case for deer, which also use this hiding strategy, although they do not belong to the same family of species as goats.

    She and her team recorded and played back young kids' calls to the female goats and recorded their responses. She explained, “Even when the calls came from kids that are five to six days old, we could see the mothers responding more to the voices of their own babies.” Hearing the voice of their own kids, the females would look towards the speaker that the sound was coming from, moving around and calling in response.

    The scientists say that understanding how goats behave and communicate is very important. “This helps us understand just how smart these animals are,” said Dr. Briefer. “Farmers might be able to change their way to raise goats considering this natural behaviour.”

Liu Yexi has taken Douyin by storm. As of Nov 17, the virtual idol, who performed on the social media platform on Oct 31, had only released two short videos but attracted over 5 million followers. 

Different from other virtual idols, Liu is defined as a "virtual beauty vlogger". In her first video, Liu is doing makeup with an eye brush while dressed in a traditional Chinese costume. 

When she turns around, the onlookers are terrified, except one boy. Then Liu slightly brushes the boy's eyes, allowing him to see the fantasy world in her own eyes. The internet users marveled(使...惊叹) at its storyline, science-fiction elements and special visual effects with cyberpunk style. Liang Zikang, the CEO of the production team, told China Newsweek that the team spent two months making the video. 

Liu's instant popularity online further reflects that the virtual idol industry in China has been booming. There are over 32,400 virtual idols that have opened accounts on video-sharing platform Bilibili in the past year, seeing a year-on-year rise of 40 percent, Chen Rui, the CEO of Bilibili, said in a speech. 

"Compared with real idols and stars, the virtual ones seem to be more approachable for fans," Shine News noted. Additionally, these virtual web celebrities(名人) won't have scandals(丑闻). 

As more young people are fascinated by these virtual figures, their commercial(商业的) value has been on the rise. Generally, they earn money by online concerts, livestreaming and related products. For example, Luo Tianyi, a well-known virtual singer, cooperated with livestreamer Li Jiaqi to promote goods in 2020. 

Therefore, some people are wondering whether they will replace real humans. "These socalled virtual idols have real human teams to back them up and control them. They are not really virtual." Ding Daoshi, an independent analyst in the internet sector, told the Global Times. The real virtual idol will come when artificial intelligence achieves a new level of selflearning and self-training and then interacts with others, he added.
