Weather Rocket Launched
A weather rocket, developed under the Meridian Space Weather Monitoring Project (Meridian Project), was blasted off at 4:00 am, June 3, 2010 from a deep space probe rocket launching site in Hainan. Applied with GPS technology, the rocket is able to collect high precision near space temperature, pressure, and wind field parameters across low latitudes at a height stretching from 20 to 60 kilometers.
The Meridian Project is a large space environment watch system, designed to monitor the middle and upper levels of atmosphere, ionosphere, and magnetosphere in a range from 20 kilometers to several hundred kilometers above the ground in a consecutive manner, using diverse means, including geomagnetism, radio, optics, and space probe rockets. It also collects geomagnetic and electric fields data in an inter-planetary space environment that is a dozen of earth radii away from the earth system.
The project will establish 15 near space environment watch stations on the ground along the line of 120 degrees east longitude and 30 degrees north latitude. The station, sitting in the Yaxing Township, Hainan Province, is a comprehensive watch site equipped with most needed functions. The station is also designed to launch space probe rockets to collect meteorological and ionosphere data for the project.
Protein Able to Eliminate Pathogenic Organisms
A study team, led by CAO Xuetao, a Chinese Academy of Sciences academician working at Second Military Medical University Institute of Immunology, reported their findings on LRRFIP1, a cytosolic nucleic acid sensor that can detect microbial RNA and DNA, and trigger the production of type I interferon. A commentary accompanying the paper said the finding pointed out a new direction for people to understand how human immune systems work on pathogenic organisms, and for designing new anti-infection immune drugs as well.
Researchers showed that LRRFIP1 bound exogenous nucleic acids and increased the expression of IFN-β induced by both double-stranded RNA and double-stranded DNA. LRRFIP1 interacted with β-catenin and promoted the activation of β-catenin, which increased IFN-β expression by binding to the C-terminal domain of the transcription factor IRF3 and recruiting the acetyltransferase p300 to the IFN-β enhanceosome via IRF3. Therefore, LRRFIP1 and its downstream partner β-catenin constitute another coactivator pathway for IRF3-mediated production of type I interferon. The finding makes a new target for designing anti-infection drugs.
Faster Express Train
Hexie 380A, a proprietary new generation express train developed by Changchun Railway Vehicles to run at a speed of 380 kilometers per hour, rolled off the assembly line on May 27, 2010. Designed to run at a speed up to 380 kilometers per hour, or 350 kilometers in a row, the new locomotive makes the fastest train in the world, with best quality, most desired functions, and enhanced safety. The high speed train is able to provide the needed comfortableness to passengers, with a reduced noise level and enhanced steadiness. The train compartment is equipped with an automated air pressure regulating system, allowing passengers to have a comfortable stay. The novel locomotive also enjoys a range of merits, including low-resistant and renewable braking, green dynamic system with zero emission, enhanced safety and reliability, automated monitoring and control, and redundancy design. The entire locomotive is characterized with ten major technical innovations, including low-resistant streamlined head, improved body vibration module, air tight body, enhanced safe bogie, advanced sound insulation and shock resistance, powerful green traction, positive dual-pantograph current collection with low disturbance, enhanced safe low-abrasion braking, individualized service facilities, and intelligent diagnosing and monitoring.
Quantum State Teleportation for 16 Kilometers
A joint research team, made up of the scientists from the University of Science and Technology of China and Tsinghua University, has successfully realized a free-space teleportation of quantum states over 16 kilometers, or 20 times the range registered in the preceding world record. The finding, reported in the June 1, 2010 issue of Nature Photonics as a cover story, confirmed for the first time the feasibility of free-space teleportation of quantum states over a long distance that is required for the deployment of quantum information network on a global scale.
In 2007, the team started to work on free-space quantum teleportation of the state of a photon over a 16 km open-air link between Beijing and Huailai in the Hebei province, and has achieved a range of key technical breakthroughs, before realizing the teleportation of quantum state over the longest distance in the world in 2009. Researchers proved the feasibility of the teleportation of quantum state through the atmosphere, and created a reliable ground for the future deployment of a quantum information network on a global scale relying on the relay of satellites.
The study was financed by a range of research programs initiated by Chinese Ministry of Science and Technology, Chinese Academy of Sciences, and National Natural Science Foundation. The finding has attracted the attention of international academic communities, and was reported in numerous international journals, including New Scientist, Physics Today, and the news portal of the American Physical Society.
Polymers Let DVD Store More
Not long ago, two labs at the University of Science and Technology of China worked together to roll out a supramolecular azopolymer system that shows good optical performance and stability for use as a high density optical information storage, based on the light-responsive nature of the polymers. Researchers believe that a 20-fold increase in information density over conventional DVDs is now possible. Researchers are currently working on the multiple level structures for the polymers, in an attempt to realize super high density information storage using applicable technologies.
The study was financed by National Natural Science Foundation, Ministry of Science and Technology, and Chinese Academy of Sciences. The finding was published in the May 26, 2010 issue of J. Mater. Chem.
Chinese Made Humidity Sounder Work Smoothly
A FY-3 weather satellite was launched on May 27, 2008 from the Taiyuan Satellite Launch Center. The Microwave Humidity Sounder (MWHS) aboard the satellite was put into operation on June 4, 2008. As of June 4, 2010, the humidity sounder has worked smoothly in orbit for two years. Equipped with two frequencies (150GHz and 183GHz) and 5 channels, the humidity sounder is mainly employed to collect global atmospheric humidity profiles and heavy rain data. The sounder was designed to work three years, with a two-year orbital operation capability. In the past two years, it has worked smoothly, and collected abundant water vapor and heavy rain data, with clearly defined images and rich information.
Comparing with similar sounders manufactured overseas, the Chinese made humidity sounder is applied with a range of innovative technologies: 1) 150GHz polarized separation using quasi-optic techniques, the first instance in the world; 2) flexible scanning capability in three modes, including scanning at different speeds, balanced scanning, and scanning at a fixed angle, allowing scanning at any angles; 3) broadband and high linear reception, with a raised scaling precision and enhanced qualitative applications; and 4) dual sounding frequencies with dual antenna configuration for expanded functions.
Possible Pathogenesis for Parkinson's Disease
A team, led by WANG Zhizhen, a Chinese Academy of Sciences academician at Institute of Biophysics, in collaboration with another team headed by JIAO Renjie, has found through a PD model study that HDAC6 plays a regulating role in triggering up the occurrence of Parkinson's disease. Researchers found that in a PD model with mutated HDAC6, the model would show noticeably aggregated symptoms of Parkinson's disease, including dying of dopamine neurons, retina deterioration, and dyskinesia. Meanwhile, the symbolic cytorrhyctes came down in number noticeably, while the soluble oligomer went up in number due to the missing HDAC6. The study unveils that HDAC6 has a noticeable inhibitory effect on the occurrence of Parkinson's disease, and that cytorrhyctes has a protection effect, with oligomer being the real cause for the disease. The finding, to be published in the July 1, 2010 issue of Molecular Biology of the Cell, provides a new potential target for preventing and treating Parkinson's disease.
New Navigation Satellite Launched
At 23:58, June 2, 2010 (Beijing time), China successfully blasted off another satellite in the Compass navigation series aboard a CZIIIC launch vehicle, from the Xi’chang Satellite Launch Center. At 18:30, June 7, the ground control in Xi’an successfully captured the satellite, and made it sit in a geostationary orbit at 84.6° east longitude above the equator. The ground control also opened up the effective payloads, including 1st and 2nd generation navigation equipment aboard the new satellite, the fourth of its kind so far deployed by China in the geostationary orbit. The development marks a step closer to the full operation of China’s own satellite navigation system.
