Photo provided to China Daily BEIJING -- China's Ministry of Science and Technology Wednesday selected the country's top 10 scientific discoveries of last year, including macaque monkey cloning, a DNA nanorobot and the precise measurements of the gravitational constant. The following are highlights of the major discoveries: 1.MACAQUE MONKEY CLONING Chinese researchers cloned the world's first macaques from somatic cells by the same method that made Dolly the sheep. It made research with customizable populations of genetically uniform monkeys a possibility, with the potential of furthering human disease research. 2.CREATION OF FIRST SINGLE-CHROMOSOME YEAST Chinese scientists have created a single-chromosome yeast, and its life functions show no difference from its wild counterparts, making it the first time in the world that organisms with multiple chromosomes were artificially transformed into single-chromosome forms. The research shows that a complex genome system can be simplified through manual intervention. This study may also pave the way for new man-made species in the future. 3.KETAMINE FOR ANTIDEPRESSION Chinese researchers reported in the journal Nature how the anesthetic painkiller ketamine blocks the neuronal activity that drives depression-like behavior. The finding may provide new perspectives on the treatment of depression and anxiety, which currently affects some 300 million people worldwide. 4.DNA NANOROBOT FOR CANCER THERAPY Chinese scientists have constructed an autonomous DNA robot programmed to transport payloads and present them specifically in tumors. The nanorobot proved safe and effective for mice and pigs. It represents a promising strategy for precise drug delivery in cancer therapy. 5.PRECISE MEASUREMENTS OF THE GRAVITATIONAL CONSTANT Chinese scientists have calculated the most precise value of the gravitational constant, one of the most fundamental constants of nature. To achieve their results, the team used both the angular-acceleration-feedback method and time-of-swing method to come close to producing an accurate value. cheap silicone wristbands free shipping

PHNOM PENH - Cambodia on Friday began the construction of a China-funded national road No. 11 that connects Prey Veng province to Tboung Khmum province in the country's southern part.The construction of the 96.4-km national road, including two bypass roads, will be done by the China Road and Bridge Corporation at a cost of $94.1 million, a concessional loan from the Chinese government.The project is expected to be completed in 44 months.Cambodian Prime Minister Samdech Techo Hun Sen and Chinese Ambassador to Cambodia Xiong Bo presided over the groundbreaking ceremony held in Prey Veng province, which was attended by about 7,000 people.Speaking at the event, Hun Sen expressed his gratitude to the government and people of China for having provided grant aid, non-interest loan, and concessional loan to Cambodia for socio-economic development."China's aid has not only boosted Cambodia's socio-economic development, but also helped strengthen Cambodia's independent foreign policy," he said.Meanwhile, the prime minister said the rise of China does not pose any threats to others, instead, it will benefit other developing countries, including Cambodia.Hun Sen said the Belt and Road Initiative proposed by China has been playing a vital role in developing infrastructure in Cambodia and other participating countries.Xiong said all China's aid and concessional loans to Cambodia are sincere and has only one goal: help Cambodia develop more rapidly and improve the living conditions of the Cambodian people.He said China's aid to Cambodia has no strings attached.The ambassador said under the Belt and Road Initiative, there are more and more Chinese investors coming to Cambodia, and they are contributing to developing the economy of Cambodia.
