Inside China’s growing use of facial recognition technology
February 15, 2018
- In the past, the country has relied heavily on cardless identification. The “Smile to Pay” feature, launched by Alibaba’s Ant Financial affiliate, lets users take a grinning selfie to authenticate a digital payment. Facial recognition in China also allows students to enter university halls, travelers to board planes, and employees to enter office premises with ease and no ID cards. In 2016, Dahua Technology set a new record for labeled faces in the wild (LFW) facial recognition, beating previous records from Baidu, Tencent, and Google. Consisting of a network with over one hundred layers, Dahua’s facial recognition system is currently the deepest network among facial recognition systems. This allows a new type of metric learning method, which can detect suspects in the crowds of Beijing and even monitor pedestrians at traffic lights in the Fujian Province. Dahua says its technology helped police arrest a number of fugitives during the G20 summit. China’s Hangzhou-based Hikvision Digital Technology claims to be the world’s largest maker of surveillance technology. The company weaves facial image modeling and a similarity calculation into the system to enable facial recognition capabilities. Users apply this solution to blacklist criminals and prevent admission of known offenders to venues like sports stadiums, parks, and casinos. Ranked 11 out of 50 on MIT’s list of the world’s smartest companies, Face++, which may be the first facial-recognition AI startup, sits on a whopping valuation of $1 billion. SenseTime has used facial recognition to help the police department nab 69 suspects in one month in southwest China. The company has a growing business relationship with the government and large data sets of a vast population, which has raised concerns about privacy. Among many other things, the company’s technology can trace the route of targets in a billion-scaled database of face image capture records and has a flexible surveillance for different times, places, and targets.
At China’s new smart gas stations, no cash, cards, or smartphone apps will be required
February 7, 2018
- How it works: When a Banma car enters the gas station, geo-fencing systems detect where it is and trigger an app on the car’s touch screen. That lets drivers select fuel, pay via Alipay, and order things from the convenience store. Humans fuel the car and bring the goods. Then the driver just … goes.
Chinese scientists develop heat-resistant memristor
- A group of Chinese scientists have developed a high temperature-resistant memristor that could address existing challenges in the development of electronic devices. The sandwich-like memristor is composed of two layers of graphene, with a layer of molybdenum disulfide in the middle. The memristor devices exhibit excellent thermal stability and can operate at a high temperature of up to 340 degrees Celsius. Memristors are a leading candidate for future storage and neuromorphic computing.

China’s breathtaking transformation into a scientific superpower
January 21 2018
- The National Science Foundation and the National Science Board have just released their biennial “Science & Engineering Indicators,” a voluminous document describing the state of American technology. There are facts and figures on research and development, innovation and engineers. But the report’s main conclusion lies elsewhere: China has become — or is on the verge of becoming — a scientific and technical superpower. China has become the second- largest R&D spender, accounting for 21 percent of the world total of nearly $2 trillion in 2015. Only the United States, at 26 percent, ranks higher, but if present growth rates continue, China will soon become the biggest spender. From 2000 to 2015, Chinese R&D outlays grew an average of 18 percent annually, more than four times faster than the U.S. rate of 4 percent. There has been an explosion of technical papers by Chinese teams. Although the United States and the European Union each produce more studies on biomedical subjects, China leads in engineering studies. American papers tend to be cited more often than the Chinese papers , suggesting that they involve more fundamental research questions, but China is catching up. China has dramatically expanded its technical workforce. From 2000 to 2014, the annual number of science and engineering bachelor’s degree graduates went from about 359,000 to 1.65 million. Over the same period, the comparable number of U.S. graduates went from about 483,000 to 742,000.
China embraces research competition in drive for greatness
January 23, 2018
- China’s flagship initiative to create more than 40 “world-class” universities is set to adopt a new UK-influenced system linking research funding to disciplinary excellence, experts have predicted. While little is known about how China will distribute huge amounts of funding under its “Double First Class” project to establish 42 “world-class” universities by 2050, new results from the country’s latest research audit have given the biggest clue as to how institutions will be funded during the world’s largest university investment programme. In the ratings, Peking University is China’s most highly regarded research university, with 21 A+ disciplinary areas and a further 11 A-grade areas, followed by Tsinghua University, which had 21 A+ areas and eight A-grade marks, the audit showed.

Scientists develop new method for more effective photothermal treatment of tumors
December 12, 2017
- Nanorods made of bismuth sulfide kill tumor cells with heat when they are irradiated with near-infrared light (NIR). Chinese scientists are now making these weapons more powerful by remodeling the defect state of the nanorod crystal lattice by adding gold nanodots. As reported in the journal Angewandte Chemie, this could be a good basis for more effective photothermal treatment of tumors. Nanomaterials made from the semiconductor bismuth sulfide (Bi2S3) are well suited for this job. Researchers working with Haiyuan Zhang at the Chinese Academy of Sciences (Changchun, Jilin, China) have now been able to clarify the mechanisms that underlie the photothermal properties of these materials. Building on this knowledge, they have been able to improve the photothermal performance of bismuth sulfide nanorods by adding gold nanodots to their surface.
Superbacteria Could Soon Be Eating China’s Factory Waste
December 12, 2017
- In a Hong Kong laboratory, researchers are working with one of the world’s biggest cloth makers to improve its production process using a special ingredient: bacteria. TAL Apparel Ltd., which has factories in mainland China and Southeast Asia, has teamed up with City University to identify bacteria that can clean up more efficiently the vast quantities of waste water the textile industry produces. It’s one of hundreds of efforts by China’s private and state-owned companies to fix a problem that could end up rewriting the playbook of the global fashion industry. The price of ensuring a sustainable water supply in China is yet another expense for factories that are already being squeezed by higher land and labor costs. And while automation and overseas production offer some respite, China’s companies are turning to other technologies to preserve operating margins that, even for major players such as Crystal International Group Ltd., can be less than 10 percent.
