1 . A humanoid robot can relay video and touch sensations to a person wearing a haptic (触觉内) feedback suit and a virtual reality (VR) headset hundreds of kilometres away, offering away for people to attend events without travelling.
The iCub 3 robot is a 52-kilogram, 125-centimetre-tall robot with 54 joints across its body. Its head contains two cameras where a human’s eyes would be, and an Internet-connected computer where the brain would go. Along with the cameras, sensors covering its body send data to the robot’s “brain”. These sensations are then reproduced on a suit and VR headset worn by a remote human operator.
When the operators react to what they see and feel, the suit’s sensors pick up the movements and the robot matches them. “The key is to translate every signal and bit of digital data that can be sent through the network.” says Stefano Dafarra, who was part of the iCub3 team. There can be a small delay of up to 100 milliseconds to capture and transmit the visual shots, but the operator can case this by moving slightly slower than normal.
The team demonstrated the robot at the Venice Biennale, where it wandered through an exhibition while its operator stood 290 kilometres away in Genoa. Dafarra hopes people will use the iCub3 to attend events remotely, reducing the need to travel. “But at present, a fall could be hugely damaging to the robot, and it’s uncertain whether it could stand up again on its own," he says.
“iCub3 is an interesting robot and offers clear advantages from the previous versions.” says Jonathan Aitken, whose laboratory owns a prior version of the robot. However, he is disappointed that the team wasn’t clear in its research about the data transmission requirements of the new version of the robot. “It would be good to know just how much data was required, and what the upper and lower bounds were.” he says.

2 . Tokyo restaurant Sushiya no Nohachi reportedly serves great sushi, but it is most famous for its gimmick—making the world’s smallest sushi with a single grain of rice.
Located in Asakusa, a slightly quieter part of Tokyo, Sushiya no Nohachi is the place to go if you want to enjoy the tiniest, most adorable sushi in the world. Each piece is made with only a grain of rice and a tiny slice of topping wrapped in the thinnest piece of nori(海苔). Every served piece is actually perfect, which hints at the amount of work and patience that Bes into making them. They are the work of Hironori Ikeno, the chef of Sushiya no Nohachi, who came up with the idea in 2002 when a client asked him how small he could make his sushi. He answered, “as small as a grain of rice”, and proceeded to demonstrate that he wasn’t kidding. Over the years, the restaurant has become internationally famous for making the world’s smallest sushi.
Despite its size, miniature sushi actually takes a bit longer to make than regular-sized me, because of the precision and concentration required to put the tiny ingredients together. That is part of the reason why the restaurant only prepares tiny sushi for customers a few times a week and no more than five times a day, although they do sometimes make exceptions for foreign visitors who travel to the restaurant just to experience the world’s smallest sushi.
“I had a client from Sweden who came just to see my tiny sushi and the moment she saw it, she literally cried with joy.” Hironori Ikeno said.
Interestingly, one cannot simply order the tiny sushi at the restaurant. It is served for f re upon request with a regular-sized sushi course. Considering the sushi served at this place is reportedly delicious, you should probably be more excited about that. Plus, it also justifies the gimmick that the restaurant is so famous for.

4 . Anyone who’s used noise-canceling headphones knows that hearing the right noise at the right time can be vital. Someone might want to remove sirens (汽笛) when working indoors, but not when walking along busy streets. Yet people can’t choose what sounds their headphones cancel.
Now, a team led by researchers at the University of Washington (UW) has developed deep-learning algorithms (算法) that let users pick which sounds pass through their headphones in real time. The system, called “semantic hearing”, works with headphones that stream the captured sounds to a connected smartphone which cancels all environmental sounds. Either through voice commands or a smartphone app, headphone wearers can select which sounds they want to include from 20 classes, such as sirens, baby cries, speech and bird chirps. Only the selected sounds will be played through the headphones.
“The challenge posed to today’s noise-canceling headphones is that the sounds headphone wearers hear need to sync (同步) with their visual senses. You can’t hear someone’s voice two seconds after they talk to you,” said senior author Shyam Gollakota, a UW professor. “This means the algorithms must process sounds in under a hundredth of a second.”
That need for speed is why the system must process sounds on a device such as a connected smartphone, instead of on cloud servers. Additionally, because sounds from different directions arrive in people’s ears at different times, the system must preserve these delays and other clues so people can still meaningfully perceive sounds in their environment.
Tested in environments such as offices, streets and parks, the system was able to capture sirens, bird chirps, alarms and other target sounds, while removing all other real-world noise. When 22 participants rated the system’s voice output for the target sound, they said that the quality improved compared to the original recording. In some cases, the system struggled to distinguish between sounds that share many properties, such as vocal music and human speech. The researchers note that training the models on more real-world data can improve these outcomes. In the near future, the researchers plan to release a commercial version of the system.
