    China's largest search engine Baidu has said it will make its latest artificial intelligence (AI) technology accessible to developers and businesses as part of the company's latest move into AI, big data and cloud computing.

    AI solution "Tianzhi" was launched at a cloud-computing summit held in Beijing Wednesday. It includes services in three fields: sensing technology, such as image and voice processing, machine learning, and deep learning, an advanced form of machine learning, said Zhang Yaqin, CEO of the Nasdaq-listed company, at the summit.

    Developers can access facial or voice recognition, algorithms(演算法) for data analysis and projections, and deep learning applications, Zhang said, adding that the technology could help users innovate in their sectors.

    "With more devices connected to the cloud, enterprises will use cloud computing and AI more frequently," said Wu Hequan, an academician at the Chinese Academy of Engineering, "Open AI technology can play a bigger role."

    The company also revealed a plan to invest 10 billion yuan (1.45 billion U.S. dollars) in cloud computing in the next five years and establish an innovation center, which will serve 10 million enterprises.

    There is a lake near a forest in Sweden. The water in lake is very clear and everything is quiet and still. On the far side of the water is some farmlands and further away, across the fields, is an old church built on a hill. It has just stopped raining. The brook flowing into the lake is full and there is still some half-melted snow from last winter on the ground.

    The reason the water is so clear and everything is so quiet and still, is that most of the plant and animal life in and around the lake is died. There are no birds because all the fish and insects, which the birds need for food, have disappeared. Many trees in the forest are losing their leaves and bark, and are sick and dying. Others were blown down by the high winds of last winter. A farmer is working in a field planting something, but unless he plants a stronger kind of seed this year, the crop will be between 25 to 40 percent lower than a few years ago. The stones of the old church tower are turning to power and unless the tower is repaired soon, it will fall down.

    The smoke coming out of factories and poisonous gases from cars and trucks causes all the death and destruction in this place. And yet this silent lake is hundreds of kilometers away from the nearest factory and highways.

It is the stock response to a parent struggling with a crying baby or a bad-tempered teenager: "Treasure every moment because they grow up so fast." Now researchers have found there may be something in the old saying. Watching children grow up really does seem to make time fly. Scientists have found that parents feel time passing more quickly than non-parents.

The findings could be due to the fact that children change fast. "Over ten years, children go through dramatic changes not only in their physical appearance, but also in their understanding abilities and their status," the researchers said. The results could also be a consequence of parents spending a large amount of their time on their children, they said, even though they found no difference in the time pressures recorded by parents compared with non-parents in the study.

For the study, published in the journal Timing & Time Perception (感知), the researchers asked 431 people aged from 20 to 59 to fill in a subjective time questionnaire, a tool used by psychologists to measure time perception. They were asked: "How fast did the last ten years pass for you?" An answer of very slowly gave a score of-2; slowly was-I; neither fast nor slow was 0; fast was I and very fast scored 2. So the higher the score, the faster they felt time had passed. The parents had an average score of I. 22, compared with 0. 76 for the non-parents.

Participants were also asked how quickly the last year, month and week had passed, but there were no differences between the groups for these shorter intervals (间隔). Previous studies have suggested that time also seems to speed up when we get older. Research published in 2019 by Duke University in North Carolina suggests this could be due to physical changes in our bodies, with a slowdown in image processing speeding up our perception of time passing.

Days that seemed to last forever in our youth were "not due to experiences being much deeper or meaningful", the researcher Adrian Bejan said, "but due to the fact that they were being processed rapidly."
