Postmates, an American delivery company, has built a robot, called Serve, which was designed to make short-distance deliveries in cities.
To know what's going on, Serve has a laser radar （激光雷达）sensor on top, in which spinning lasers let it detect objects around it and know how far away they are. Also, behind each artificial eye is a camera, with six more imaging devices spread around the robot. Inside it is another sensor that allows Postmates to know if there is a package in there.
“One of our key decisions early on was to rely heavily on the robot’s ability to see the environment,” says Ali Kashani, the vice president for robotics at Postmates. Since the sidewalk is “a very chaotic environment”，he points out, the robot needs to be able to take it all in and figure out what to do. This robot, and many like it, also must be able to signal their intentions to the pedestrians. For that，it has a number of approaches. One is using its eyes; another is a colorful light ring that goes around the top. “When it wants to make way for a pedestrian, it will use its eyes and look down，” he explains. It can also use the lights on the top as a turn signal，which is obvious, and also look left and right when it’s turning left and right.
Using eye movements and other silent signals is a good idea，” says Aaron Steinfeld, a professor on human-robot interaction （互动）.Serve is intended for sidewalks * and Steinfeld says that environment is challenging. People usually walk fast while staring at a smartphone. For a robot，that’s a lot. “We have active research on robot moving socially around walking people,” he says. “And it，s really tricky to do this well. ”
Postmates plans to use Serve in Los Angeles at first, and that its intended task is to move small objects over short distances”. The robot can travel 30 miles on one charge and is able to carry 50 pounds.

It is all because of Lensa, an app which uses artificial intelligence to present digital portraits based on photos users submit.
Lensa recommends users submit 10-20 selfies for the best results. The pictures should be close-up of your face with a variety of different backgrounds, facial expressions, and angles. A yearlong subscription to the app, which also provides photo editing services, costs $35.99. But you can use the app for a weeklong free trial if you want to test it out before committing.
To test out the app, I took 20 selfies I thought showed a variety of expressions and angles and submitted. It took around 20 minutes for Lensa to return my portraits, which fell into several categories: fantasy, fairy princess, focus, pop, stylish, light, kawaii, and cosmic. In general, I felt like the app did a decent job producing artistic images based on my selfies.
Other users have documented unfavorable experiences which come from their Lensa images. Aubrey Gordon, a writer and fat rights activist, wrote on her Instagram the app produced images which made her look much thinner than she actually is. “Lensa is really working overtime to make AI me into a thin person,” she wrote in the caption.
Several of the artists expressed concern the apps could also threaten their livelihoods. Digital artists cannot compete with the low prices and fast turnaround artificial intelligence enables for a digital portrait, they said at the time.
Lensa’s owner Prisma has tried to relieve anxiety that digital artists will be robbed of work opportunities owing to the technology. “While both humans and AI learn about artistic styles in semi-similar ways, there are some fundamental differences: AI is capable of rapidly analyzing and learning from large sets of data, but it does not have the same level of attention and appreciation for art as a human being.”

【推荐2】Norway' s capital Oslo will become the first city in the world to use wireless (无线的) charging systems for electric taxis, hoping to make recharging quick.
The project will use induction(电磁感应)technology, with charging plates (板) in the ground at taxi stands where taxis line up to wait for passengers,Finnish company Fortum, said on Thursday.
"Receivers will be in a taxi, and when it drives up to the charger, a wireless charging process will automatically start. This will allow the taxis to charge in a place where they would anyway be waiting for new customers, says Annika Hoffner, head of Fortum.From 2023 all taxis in Oslo will have to be zero emission (排放) and Norway wants all new cars to be zero emission by 2025. Among other nations, Britain and France have similar goals for 2040.
Fortum is working with US firm Momentum Dynamics and the city of Oslo on the system. It said the greatest difficulty with electrification of taxis is that it takes too much time for drivers to find a charger, and then wait for the car to charge.
"Time equals money when taxi drivers are working," said OleGudbrann Hempel, head of
Fortum' s public charging network in Norway.
Norway has the world' s highest rate of electric car ownership, partly thanks to measures such as free or discounted road fees, parking and charging points. If you buy an electric car, you do not need to pay the same taxes (税) as those on traditional cars,which are very high in the country.
Last year, almost one in three new cars sold was electric.With just five million people, Norway bought 46, 143 new electric cars in 2018, making it the biggest market in Europe. It is ahead of Germany which bought 36,216 and France which bought 31,095,according to the European Automobile Manufacturers' Association.

【推荐1】Jennifer Brophy, a professor of Stanford, is working on methods that she hopes will be used to improve commercial plant species so that they can survive harsh conditions. Initially, she studied green architecture in her undergraduate years. Once she started taking architecture classes, she realized it wasn’t her passion — but when she encountered an article about a company that creates biofuels (生物燃料) from bacteria, something clicked. “I thought that was just the coolest thing. It got me really interested in pursuing bioengineering,” she says.
Today, Brophy is developing new genetic engineering techniques that can help plants grow in various conditions. By changing the genome (基因组) of both commercial crops and soil bacteria, she thinks it’s possible to help plants survive droughts.
Brophy is building what she calls “genetic circuits”. Besides changing the genes within plant cells, this method also changes how and when those genes are triggered. If the plant senses a specific sugar, it can express one protein; if it senses another signal, it’ll express a different protein. If both signals are there, the plant may be able to express something else entirely. ”Using circuits to all these different inputs,“ she says.
“A plant doesn’t necessarily know what’s coming. It just knows whether it’s hot or temperate right now,” says Brophy. This can lead to problems when weather becomes erratic. A plant that usually flowers in spring may flower in winter if there’re a few unseasonably warm days. When temperatures fall again, the flowers die, which ruins a year of crops. “It’d be great to be able to communicate with plants to tell them, ‘Hey, you should wait on that flowering,’” she adds.
Brophy is still testing the concept in the lab using a small weedy plant called Arabidopsis. She notes engineering crops in the future may also involve genetically modifying soil bacteria. As the bacteria’s surroundings change, they could potentially send out chemical signals that tell nearby plants to shift their growth accordingly. Brophy thinks engineering crops could benefit farmers and society at large.

【推荐2】A person suffering from paralysis (瘫痪) was able to independently drink water by using his brain to control a special glove serving as his hand. It sounds like magic, doesn’t it?
This was a recent breakthrough in brain-machine interface (BMI) technology by a team of Chinese scientists and doctors. BMI refers to creating a connection between the human brain and external devices, making direct communication between the brain and computers. For paralyzed people, it helps control the body through thoughts in the brain cortex (大脑皮层) and do simple things by themselves. On Oct 24, 2023, the team completed the first clinical trial on the patient, using wireless minimally invasive (微创的) BMI implantation (植入). Two coin-sized BMI processors were implanted into the patient’s skull (颅骨), successfully receiving neural signals (神经信号) from the brain. After three months of home rehabilitation (康复) training, the patient can now use his brain signals to control a special glove powered by air pressure. This helps him do things like drinking water independently.
The significance of the project is that the patient’s neural tissue was not damaged during the process, whereas previous attempts may have such risks. It also uses a wireless power supply, meaning that the implanted device does not require a battery. BMI is now mainly applied in the medical field to help improve the quality of life for those who have trouble moving or speaking due to brain-related issues. Additionally, BMI has simple applications for healthy individuals, such as monitoring attention span, fatigue (疲劳), and sleep, as well as serving as a simple interactive gaming device.
In China, BMI technology is still in the early stages of research and development, with no products available yet on the market. Some people are worried that psychologically experiments may affect the autonomy (自主性) and even personality of the patients. Meanwhile, ethical concerns (伦理问题) related to BMI users also need to be addressed. These include patient privacy and whether the patient has a clear understanding of what is involved when agreeing to take part in the experiment.

【推荐3】What makes us human？Is it our thoughts？Our emotions？Our behavior？
All of these things make us who we are，but at the center of it all lies the genome — the genes inside our bodies that determine everything from our hair color to our intelligence. But if we could change our genome，would we still be human？
Recently，a group of scientists from the US and South Korea worked together to successfully“edit”a human embryo（胚胎）and remove a genetic mutation（变异）that would have led to heart disease. This was achieved with the help of CRISPR-a gene — editing tool that allows scientists to edit the genome by cutting，changing or adding to parts of it.
Scientists involved in DNA editing are certain about the good of their work，and hope that in the future，diseases could simply be“edited out”.
However，others aren't so sure. People are worried that the science could be used not only to remove life-threatening illness，but also to make a“perfect”baby whose DNA has been chosen to improve its intelligence or other qualities. They say that this is a shallow way of thinking about raising children.
“It makes you think about who we are as people，and it makes you ask if humans should use the kind of power…that is changing human evolution（进化），”Jennifer Doudna of the University of California said.
Still，others worry that DNA editing could be turned into an expensive service that would only be available to the people who could afford it. That might mean the rich would be given another advantage in a world where they already have plenty of them.
“You could find wealthy parents buying the technology for their children, leading to even greater inequality than we already live with,”Marcy Darnovsky, director of the San Francisco Center for Genetics and Society, said.

【推荐1】Imagine stepping out your front door and standing in the middle of a national park. Daniel hopes this might soon be possible for millions of London residents. Daniel is leading a campaign to make London a national park city.
Although London has much more concrete than a national park usually would, it is home to more than 13,000 kinds of wildlife. These species live in its 3,000 parks, along with 15,000 varieties of flowering plants, and more than 300 species of birds. In fact, 47 percent of the land in London is green space.
“We have 8 million trees in London; it’s the world’s largest urban forest,” Daniel says. That’s almost one tree for every person living in London! Yet, even though London has thousands of outdoor spaces, one in seven children living there hasn’t visited a green space in the past year.
Daniel believes that making London into a national park will protect the animal life and green spaces in London. He hopes it will also encourage people, especially young people, to spend more time outdoors. Daniel takes his own son out to explore in London, and he thinks that other parents should do the same. Daniel believes that people who spend a lot of time in nature live happier and healthier lives. What do you think?

【推荐2】At what age are you too old to achieve breakthrough success in your field? That question attracts so many people, because almost nobody considers themselves already entirely successful.
But a huge new study, examining the careers of nearly 3,000 scientists from 1893 on, reaches an unexpected result. It’s not that youth wins out, nor that years of experience lead to the final success.What counted more was productivity, which means you should keep trying. If you want to publish a famous physics paper, the most important thing isn’t to be young and energetic, nor old and wise. It’s to publish a lot of papers.
To be fair, other studies show age does matter sometimes: maths prefers the young; and ballet or athletics aren’t exactly welcoming the old.Personality also influences the age at which success strikes. The economist David Galenson studies a group of creative geniuses, and his work implies age matters little. He once asked literature experts to make a list of America’s 11 most important poems, then looked up the ages at which they’d been composed: a wide range, from 23 to 59.
We’re in the world of the“focusing illusion”. We exaggerate(夸大)the importance of one factor(in this case, age) simply by thinking a lot about it. Something similar happens in romance (爱情): we worry about whether partners should have similar personalities, or whether opposite personalities attract-when in fact, neither plays a big role in predicting relationship success. Then there’s children raising. As a new parent, I’ve been confused about endless contradictory(矛盾的)advice on what works,and a new book on parenting concludes that different cultures take different ways, and most kids turn out OK.
In short: you’re probably not too old to achieve success. You don’t need to worry about your partner’s personality. And your parenting style probably won’t end in disaster-though that.
1. Which is the key factor to final success according to the new study on scientists?| A．Constant efforts. | B．A young age |
| C．Rich experience. | D．Broad knowledge. |
| A．To compare different study results. |
| B．To introduce a new topic to discuss. |

【推荐2】Jade Stephenson has always loved her grandmother’s wedding dress (结婚礼服). So much so that once, Stephenson even asked her grandmother to keep hold of it so she could wear it for a special day. And when she realized her 80-year-old grandma wouldn’t be able to travel to attend her graduation at Liverpool Hope University, Stephenson knew the time had come.
“I tried the dress on several years ago, so I knew what it looked like when I put on the dress and her face then lit up,” she said. “So I knew asking her if I could wear it for graduation would make her smile. Also, my grandfather died in 2009 and to me, it felt like part of him was there with me on such a special day.”
Stephenson sported the dress under her cap and her clothes last week, at the ceremony (典礼) to collect her teaching degree at Liverpool Metropolitan Cathedral of Christ the King.
Nora, her grandmother, lives in Carlisle, more than 130 miles from Liverpool. She was very happy when she saw the pictures of her granddaughter, and praised that she chose that dress for her special day.
“My grandma and I are very close. I speak to her when I can and whenever I’m home I catch up with her. I see a lot of my own characters in her. I think we have quite a lot in common,” Stephenson said. “I’ve always loved my grandma’s dress. Although it’s 32 years old, it’s fit for me.”
Stephenson said several people praised her for her choice for the ceremony. “I think people thought it was quite heart-warming. Considering how old it is, the dress is in really good condition. My grandmother has looked after it very well.”

The American writer, Sally Seamans, tells young students some smart ways to make friends .Sally says finding friendship is just like planting a tree. You plant the seed and take care of it to make it grow .
First you should choose a friend. What makes a good friend? It is not because a person has money or good looks. A good friend should be kind and patient. For example, if you have a bad day, a good friend should listen to your complaints and do his best to help. To make friends, you cannot be too shy. You should make each other happy and share your lives .
But things cannot always be happy. Even the best friends have fights. What should you do when you have a fight with your friend? You have to talk to him or her. When there is no one around, have an honest talk. If he or she doesn’t want to talk, you could write a letter .
There are three steps to be friends again:
Tell him or her how you are feeling; say what your friend has done wrong; explain why you did this or that. Remember that friendship is the most important thing in your life .
