An experiment by a research team at Beijing University was hailed as “revolutionary” in the field in a paper published in the latest issue of Science magazine on Friday. The live virus used in the vaccine used by the researchers had its genetic code tweaked to disable the viral strains’ self-replication mechanism. But it was kept fully infectious to allow the host animal cells to generate immunity. Using live viruses in their fully infectious form was considered taboo, as viruses spread rapidly. Vaccines sold and used widely today generally contain either dead or weakened forms of viruses. The animals infected with virus were cured after receiving the injection, according to the paper. This breakthrough promises to simplify the process of producing vaccines, which may help scientists develop effective vaccines or even cures for various viruses – such bird flu, SARS, Ebola and HIV – within weeks of an outbreak.

He and his colleagues from US and China have documented the algorithm at work in seven different brain regions involved with those basics like food and fear in mice and hamsters. “Intelligence is really about dealing with uncertainty and infinite possibilities,” he said, “It appears to be enabled when a group of similar neurons form a variety of cliques to handle each basic like recognizing food, shelter, friends and foes. Groups of cliques then cluster into functional connectivity motifs (FCMs) to handle every possibility in each of these basics. The more complex the thought, the more cliques join in.”

The X-ray pulsar navigation satellite — XPNAV-1 — was sent skyward at 7:42 AM (local time) atop a Long March 11 solid-fuelled rocket from the Jiuquan Satellite Launch Center in China’s northwest. China's new system is expected to be a significant improvement over the earth-based systems currently used by spacecraft as it would eliminate the time delay with sending signals back to Earth and processing.

The Long March 5 rocket, lifted off from the Wenchang launch center on Hainan Island, off China's southern coast, at 8:43 a.m. EDT (1000 GMT; 8:43 p.m. Beijing time), carring to orbit an experimental satellite called Shijian-17, which is designed to test electric-propulsion technology. Capable of 25 metric ton payload to LEO, LM 5 is among the most powerful rockets in service. Besides scheduled launch of China's upcoming space station, the Long March 5 will also loft Chang'e-5, a robotic sample-return mission to the moon. Chang'e-5 is currently scheduled to lift off sometime next year, Chinese space officials have said.

General Zhang Youxia, chief commander of China's human spaceflight program has declared today's launch a success. "According to the report of the Beijing Central Control Center, the rocket is flying according to its original plan, and the Shenzhou spacecraft has entered into its preliminary orbit," Zhang said. "The solar panel has been unfolded, and the crew is in great condition. Hereby, I announce the launch of the Shenzhou 11 manned spacecraft is a complete success." The two astronauts will spend upto 30 days in the space lab and then return to earth.

In Shanghai, for instance, less than 20 percent of existing rideshare vehicles meet the proposed (wide) wheelbase requirements. There will be significant decrease in the number of rideshare drivers. Of over 410,000 activated driver accounts in Shanghai, only less than 10,000 are residents with Shanghai residency registration.” said Didi on its social media outlets. In China, ridesharing drivers are usually migrant workers who have few other choices of employments, and rich urban residents are not interested in such jobs. Given the sore state of economy in China, high unemployment would mean social unrest; the ridesharing economy may prevail at the end as it has become too big to be strictly regulated. Separately, the Chinese government opened an antitrust probe into Uber’s sale of its China operations to Didi in September after the announcement of the merger.

Like its predecessor Tiangong-1, Tiangong-2 is an orbiting space lab – but this latest model has made several improvements in the series. Among the advances: astronauts can remain on the station up to 30 days; New systems allow in orbit refueling of propellant; and 14 new experiments in a wide range of sciences including composite material fabrication, advanced-plant cultivation, gamma ray burst polarization, fluid physics, space-to-earth quantum communications. The space lab is also equipped with a cold atom space clock, that has an estimated precision of 10 to the power of minus 16 seconds, or a one-second error every 30 million years, enhancing accuracy of time-keeping in space by one to two orders of magnitudes. This exactitude will help measure previously undetectable fluctuations for experiments conducted in zero-gravity.

At Alibaba Group Holding Ltd., four engineers tried to rig the distribution system of the e-commerce giant’s mooncake selloff—and were fired for their effort. Alibaba confirmed it fired the four this week, after they hacked into the internal website that allows employees to purchase the company’s signature mooncakes, with an orange fluffy Alibaba mascot inside.On Chinese social media, however, the now dismissed engineers were praised with job offers for their entrepreneurial instincts and technical competence.

It said the wild panda population jumped to 1,864 in 2014 from 1,596 in 2004, the result of work by Chinese government and agencies to enforce poaching bans and expand forest reserves. However, China itself disagrees with the reclassification. China's State Forestry Administration said that it disputed the classification change because pandas' natural habitats have been splintered by natural and human causes. The animals live in small, isolated groups of as few as 10 pandas that struggle to reproduce and face the risk of disappearing altogether, the agency said. International groups and the Chinese government have worked to save wild pandas and breed them at enormous cost, attracting criticism that the money could be better spent saving other (less cute) animals facing extinction.

On Sunday, Dr Yang Chen-ning, co-winner of the Nobel Prize in physics in 1957 and now living on campus at Tsinghua University in Beijing, released an article on WeChat opposing the construction of the collider. He said the project would become an investment “black hole” with little scientific value or benefit to society, sucking resources away from other research sectors such as life sciences and quantum physics. Yang’s article hit nearly all social media platforms and internet news portals, drawing tens of thousands of positive comments over the last couple of days. The first stage of the project was estimated to cost 40 billion yuan (US$6 billion) by 2030, and the total cost would exceed 140 billion yuan (US$21 billion) when construction is completed in 2050, making it the most expensive research facility built in China. Yang’s main argument was that China would not succeed where the United States had failed. A similar project had been proposed in the US but was eventually cancelled in 2012 as the construction far exceeded the initial budget. Yang said existing facilities including the Large Hadron Collider contributed little to the increase of human knowledge and was irrelevant to most people’s daily lives. But Dr Wang Yifang, lead scientist of the project with the Chinese Academy of Sciences’ Institute of High Energy Physics, argued research in high energy physics lead to the world wide web, mobile phone touch screens and magnetic resonance imaging in hospitals, among other technological breakthroughs.

Launched at 1:40pm ET, the Quantum Science Satellite is designed to distribute quantum-encrypted keys between relay stations in China and Europe. When working as planned, the result could enable unprecedented levels of security between parties on different continents. China’s new satellite would put that same fiberb-based quantum communication system to work over the air, utilizing high-speed coherent lasers to connect with base stations on two different continents. The experimental satellite’s payload also includes controllers and emitters related to quantum entanglement.

The China Aerospace Science and Technology Corporation is beginning advanced research on a high tech, more efficient successor to the retired Space Shuttle, with hybrid combined cycle engines combining turbofan, ramjet, scramjet and rocket engines, that can takeoff from an airport's landing strip and fly straight into orbit. CASTC's rapid research timeline also suggests that the reports in 2015 of a Mach 4 test flight for a recoverable drone testbed for a combined cycle ramjet/turbofan engine were accurate. And China also has the world's largest hypersonic wind tunnel, the Mach 9 JF-12, which could be used to easily test hypersonic scramjets without costly and potentially dangerous flight testing at altitude. Its nearest competitor, the British Skylon in contrast uses pre-cooled jet engines built by Reaction Engines Limited to achieve hypersonic atmospheric flight, as opposed to scramjets. Both spacecraft will probably first fly around the mid 2020s.
