【推荐1】It’s easy to forget what communications life was like before 4G. Since its introduction around 2010, mobile subscribers using 4G have enjoyed excellent connectivity. They can stream music, videos and movies, even while conducting video chats. But over the next few years, the launch of 5G networks around the world will bring in exciting capabilities that are much more advanced and beneficial.

Due to 5G’s higher connection speed, mobility and capacity, this next-generation network is expected to enable innovative software for a range of advanced applications. For example they permit surgeons to perform microscopic surgery from remote locations.

Communications service providers (CSPs) will continue to support existing networks while they invest in new infrastructure (基础设施) to support 5G. In a recent blog, Jean-Pierre Brulard, VMware senior vice president, writes: “For CSPs, it is major project, which is why it is likely that rather than a pure 5G network, the majority of people will see a blended approach, where 4G is available to deliver basic services, and 5G is introduced for specific tasks.

Brulard adds, “With 5G, companies can access the levels and speed of connectivity they need by taking advantage of the game-changing technologies — such as Internet of Things (IoT), edge computing and AI — that are going to shape the next stage of the digital revolution.”

Processing IoT and AI in an accelerated 5G world means computing, storage and networking need to be done closer to the end user, which is different from the traditional data center method of data processing. Organizations can remotely manage, monitor and secure thousands of locations and millions of diverse devices. This helps to ensure the rapid delivery of the latest apps, containers and infrastructure updates.

5G can lead to better, accelerated access to healthcare and education, and people can enjoy safer driving conditions, among other digitally fueled benefits.

Don't worry. The new NoPhone might be just the thing you need, It looks and feels exactly like a smart phone, but it does nothing. It's just a piece of plastic that you can carry around in your hand to fool yourself.

Nophone is currently a prototype (手机模型) that will cost only $12 once it hits the market. Its makers are trying to raise $30,000 in order to cover the production and marketing costs.

Dutch designer Ingmar Larsen, who helped create the NoPhone, said that he had the idea as a joke along with his friends Van Gould and Ben Langveld. To their great surprise, the idea received a lot of attention online and people from all over the world started placing requests for NoPhone of their own, so that's when the three friends decided to raise money for mass production.

David H said, “I used to sleep with my phone in my hand, but my night terrors would cause me to throw it across the room in an unconscious panic. With the NoPhone, I can still enjoy the comfort of holding a phone in my sleep, without waking up to a broken screen. Thanks, NoPhone.”

If you're interested in NoPhone, but concerned about not being able to take selfies anymore, don't worry. The makers do have an update at no extra charge—the mirror sticker. That way, they say, you can enjoy “Yreal-time” selfies with your friends when they're standing right behind you.

Describing the smell can be a challenge. And mere adjectives will likely be of little use to future generations of historians trying to document, understand or reproduce the scent of slowly decaying books. Now, that task may have just gotten easier thanks to the Historic Book Odor Wheel.

In one experiment, researchers asked visitors at the historic library to characterize the scents they smelled. All the visitors selected words like “woody”, “smoky” and “earthy” from the list, and described the smell’s intensity and perceived pleasantness. In another experiment, the study authors presented visitors to the Birmingham Museum with eight smells — one of which was an unlabeled historic book scent and seven were non-bookish, such as coffee, chocolate, fish market and dirty clothes. The researchers then had those museum goers describe the historic book smell.

The top two responses? Chocolate and coffee. “You tend to use familiar associations to describe smells when they are unlabeled,” study author Cecilia Bembibre says.

The team even analyzed the volatile organic compounds (VOCs) (挥发性有机化合物) in the book and the library. Using the data from the chemical analysis and visitors’ smell descriptions, the researchers created the Historic Book Odor Wheel to document the “historic library smell”. Main categories, such as “sweet/spicy”, fill the inner circle of the wheel; descriptors, such as “chocolate/cream”, fill the middle; and the chemical compounds likely to be the smelly source, like furfural, fill the outer circle. The researchers want the book odor wheel to be a tool that “untrained noses” can use to identify smells and the compounds causing them, which could address conservators’ concerns about material composition and historic paper conservation. And hopefully, smells of the past can be reproduced in the lab someday and museums and historians can use it to reconstruct a past we can no longer smell.

【推荐3】A joint research team recently have developed a new electronic skin that is similar to human skin in strength, durability(耐久性) and sensitivity. The skin or e-skin may play an important role in next-generation personalized medicine, soft robotics and artificial intelligence.

“The ideal e-skin will mimic(模仿) the many natural functions of human skin, such as sensing temperature and touch, accurately and in real time,” says leading researcher Yichen Cai. However, making suitably flexible electronics that can perform such delicate tasks while also used repeatedly is challenging, and each material involved must be carefully engineered.

Most e-skins are made by putting an active sensor on the surface that attaches to human skin. However, the connection between them is often too weak, which reduces the durability and sensitivity of the material; otherwise, if it is too strong, it won’t be flexible enough, making it more likely to break the circuit.

“The landscape of skin electronics keeps shifting at a remarkable pace,” says Cai. “The discovery of 2D sensors has accelerated efforts to turn these quite thin but strong materials into functional, durable artificial skins.”

The new man-made skin built by the researchers could sense objects from 20 centimeters away. It could further make a quick response when touched in less than one tenth of a second. “ It is a striking achievement for an e-skin to maintain toughness after repeated use,” said Shen, “which mimics the softness and rapid recovery of human skin.”

This type of e-skin could monitor a range of biological information, such as changes in blood pressure, which can be detected from movements of arms and legs. This data can then be shared and stored on the cloud via Wi-Fi.

“One remaining problem to the widespread use of e-skins lies in mass production of high-resolution sensors,” adds group leader Vincent Tung “ however, the latest technology offers new promise. ”
