As Internet users become more dependent on the Internet to store information, are people remember less? If you know your computer will save information, why store it in your own personal memory, your brain? Experts are wondering if the Internet is changing what we remember and how.

       In a recent study, Professor Betsy Sparrow conducted some experiments. She and her research team wanted to know the Internet is changing memory. In the first experiment, they gave people 40 unimportant facts to type into a computer. The first group of people understood thatthe computer would save the information. The second group understood that the computer would not save it. Later, the second group remembered the information better. People in the first group knew they could find the information again, so they did not try to remember it.

       In another experiment, the researchers gave people facts to remember, and told them where to find the information on the Internet. The information was in a specific computer folder (文件夹). Surprisingly, people later remember the folder location (位置) better than the facts. When people use the Internet, they do not remember the information. Rather, they remember how to find it. This is called "transactive memory (交互记忆)".

       According to Sparrow, we are not becoming people with poor memories as a result of the Internet. Instead, computer users are developing stronger transactive memories; that is, people are learning how to organize huge quantities of information so that they are able to access it at a later date. This doesn't mean we are becoming either more or less intelligent, but there is no doubt that the way we use memory is changing.

    Meet big brother Blue and his sisters Meadow and Little Willow, a family of three blind cats that got adopted by the family Catherine Magno.

    Their story starts just before the Christmas of 2014 when the kittens (小猫) were found in an abandoned house in Dubai. By then they had already lost their sight due to a cat flu that was left untreated by their previous (先前的) owner. After that they came to an animal home. At some point, brother Blue almost got adopted by the previous owner's neighbor, but the poor confused cat couldn't bear living without his sisters and cried all night while searching for them. Soon they were all united in the animal home until the important night of 19 February 2015, when Catherine took under her wing.

    “I had zero experience having adopted my first ever rescue kitten just a couple of months ago,” Catherine said. “But their story touched my heart so much that I couldn't bear the thought of them being put in a cage for a very long time or even worse.”

    Catherine was worried about the special needs of her new pet friends: “My worry was that it's going to not only be challenging but also require a lot of adjustments on my part,” but apparently it wasn't that much different. “The only adjustment early on was keeping everything where it was but they are soon adaptive(适应的).” And as she wonderfully put it: “Blind pets see through their hearts.”

    LIANG TAO sold 80 pink Givenchy bags in 12 minutes. Becky Fang sold 100 Mini Cooper cars in just five. Both are wanghong, literally “red-hot on the web”. Every day millions of Chinese search social media for wanghong posts or tune in to live-streams for wanghong's opinions on everything. The fans are helping this new Chinese Internet star to make money out of their popularity—and to shake up the country's e-commerce industry in the process.

    A few of wanghong have been hired by luxury brands. Jaeger-LeCoultre, a Swiss watchmaker, hired Papi Jiang for a video ad targeting young urbanites (都市人), including her 27m fans on Sina Weibo, a Twitter-like microblog. Zhang Yi of iiMedia Research, a consulting firm, estimates that up to 15% of sales on shopping sites like Taobao or social-media apps such as WeChat are influenced by wanghong's public support. The length of a dress might be decided by a survey of a wanghong's fans; its launch date might be based on the number of hits, shares or comments it collects, some of which can cause last-minute design changes.

    This poses a new challenge for retailers(零售商), whose supply chains must respond ever more quickly to wanghong's opinions. Whereas previously a company would look for a celebrity to match its image, wanghong and their admirers are shaping goods.

    Another challenge comes directly from wanghong themselves. They increasingly make money not merely from online support or advice but by launching their own e-commerce stores. Sales of goods accounted for just under half of wanghong earnings of 53bn yuan ($8bn) in 2016, estimates Analysys, a Chinese market-research firm (the rest came mostly from live-show tips and adverts).

    Some wanghong are going a step further. In November Becky Fang launched her own clothing line. Part of her motivation, she says, was that the brands she supported did not always match the trends she was sharing with her followers. By creating her own brand, Becky's Fantasy, she have full control of the quality. She also gains a new income. For the time being only 3-5% of wanghong follow Becky Fang's example, iiMedia Research estimates. But it expects the model to become an industry in its own right, including entertainment and e-commerce, and driven by online data.

    Humans make mistakes. Even surgeons with years of experience are not infallible. But what if these doctors could pool their knowledge and experience together and create a surgical standard of care, to be carried out by machines?

    That's the idea behind surgical robots, which may soon perform most surgeries, from sewing up tiny wounds to performing heart procedures. Many of these operations are, in fact, already completed with the assistance of robots. But a recent test suggests that robots in the operating room may soon go a step further, performing on soft tissue completely on their own, from start to finish.

    The Smart Tissue Autonomous Robot（STAR）, successfully completed surgeries on pigs. "We're the first group to develop autonomous robotic surgery with soft-tissue surgery, and when compared to standard operation, it's better, "says Peter Kim, professor of surgery. "The idea is not to replace surgeons；it will make the surgeons better and make the procedures safer. "

    A recent Mayo Clinic study found that major surgical errors-including operating on the wrong site or side of the body, or even leaving tools or objects inside the patient-occur every one out of 22, 000 procedures. That's rare, but robots like STAR would aim to lower the number even further.

    In the da Vinci surgical system, surgeons place their arms inside instruments and use their hands to control the movement of robotic tools on the operating table from afar. The robot's every major move is controlled by surgeons, and thus its results may vary based on the surgeon's training or experience.

    STAR, on the other hand, is entirely autonomous. It's not only able to work on its own and perform surgeries with a more flexible "hand", but it's able to react to the unexpected incidents. Cutting into hard tissue like bones is one thing, but operating on moving soft tissue is far more complex. STAR reacts to a changing environment, similar to how self-driving cars are programmed to not only drive on the highway, but also react to another driver making a mistake and getting in your way.

Hot Technology Products at CES 2020

The consumer electronics show, or CES, presents new technology developments annually. Here are some latest products launched at CES 2020.

The Sero TV

Samsung introduced a TV that can be used to watch video designed for a smartphone. The Sero TV does this by turning itself from the normal TV position to an upright position that looks like the shape of a phone. The V can connect to mobile devices to play video directly from the phone.

Smart waste can

A company called TOWNEW presented; waste can designed for the home that does a lot of the dirty work on its own. When the can is full, the user touches a button to activate the machine's smart abilities. The device then completely closes off the waste bag inside, puts a new one in place, all by itself, and raises its top so the user can pick up and throw away the bag.

Invisible car hood(引擎盖)

Automobile industry company Continental showed off a new technology that seems to make the front end of a vehicle disappear. The technology, called "Transparent Hood," aims to make driving safer and easier. Cameras provide video of the area underneath the vehicle, permitting the driver to see objects and road conditions that might present danger.

Wearable air purifier

A company called Aō Air introduced a wearable air purifier. Designed to be a high-tech face covering to block pollution, the device pulls air through a filtration(过滤)system and then uses fans to create a small area of clean air at its front, allowing the air to be purified-without the need for a solid container.
