China launches Tianhui-1C mapping satellite of Tianhui-1 series
China has successfully launched Tianhui- 1C, a third mapping satellite of the Tianhui-1 series into its designated orbit. The mapping satellite was launched by Long March 2D carrier rocket from the Jiuquan launching base located in the country’s northwestern Gansu province. It was overall Long March rockets series 215th successful launch. The satellite was developed and produced under the auspices of China Aerospace Science and Technology Corp (CASTC) which is China’s primary launch vehicle and satellite contractor.
Applications : Tianhui-1C satellite will enhance the China’s ability to carry out scientific research, mapping and disaster relief. It will be also used for scientific experiments, land resource surveys, mapping, crop yield estimation and disaster relief. The first Tianhui 1 mapping satellite of the series was launched in August 2010.
Scientists develop 3-D printing method to make embryonic stem cells
Scientists from China and United States have developed a 3-D printing method to produce highly uniform ‘blocks’ of
embryonic stem cells. The method was developed by the researchers from Beijing based Tsinghua University (China) and Philadelphia based Drexel University (US). The new method used extrusiondeposition based 3-D printing technology to produce a grid-like 3-D (three dimensional) cell structure to grow embryoid body. This 3D printed embryoid body demonstrated cell viability and rapid self-renewal for 7 days by maintaining high
The grown embryoid body in such a controlled manner is uniform and homogenous and serves as a basic starting
point for further tissue growth.
Potential Applications: These cells are capable of generating all cell types in the body which could be used as the ‘Lego bricks’ to build larger structures of tissues, tissue constructs and even micro-organs.
This technique can be further enhanced to produce embryoid body at a high throughput, providing the basic building
blocks for tissue regeneration and for drug screening studies.
China launches China Sat2C
Civil communications satellite ChinaSat 2C was launched by China recently. China put a new communication satellite into orbit from the southwestern Xichang Satellite Launch Center. It was carried by the Long March-3B carrier rocket. It will provide radio, TV transmission and broadband services for the country’s radio stations, TV stations, radio transmitting stations and cable networks.
The satellite was developed by the China Academy of Space Technology and is owned by China Satellite Communications Co., Ltd. This is the 216th mission of the Long March carrier rocket series developed by China Aerospace Science and Technology Corporation.
Tsunami early Warning system successfully tested
A newly installed tsunami early warning system siren was successfully tested in Mumbai recently. It was tested nearly 11 years after the Boxing Day tsunami which had hit the east coast of India and had killed more than 10,000 people. Key facts: The siren system has been installed at the Meteorology Office of Western Naval Command by Indian National Centre for Ocean Information Services (INCOIS). It has a digital electronic board fitted in the system which gives out data about the approaching tsunami. The system has a radical range of 3 kms in all directions and gives continuous hoot for 60 seconds during emergency.
The siren will be remotely controlled by Hyderabad based INCOIS and will operate in case of a possible Tsunami threat in the local region. 7 tsunami buoys with sensors will record the speed and height of waves. It will further alert the monitoring centre in Hyderabad. The warning siren will provide precise tsunami alert to Brihanmumbai
Municipal Corporation (BMC), disaster management authorities and Indian Navy to prevent the possible damage. In 2005, Indian Government had started its own interim tsunami warning centre after the devastating tsunami which had hit the Indian Ocean countries on December 26, 2004.
FDA approves first genetically modified salmon for consumption
AquaBounty Technologies’ salmon became the first genetically engineered animal to receive U.S. approval for human consumption, setting the stage for more such approvals. The U.S. Food and Drug Administration said that the company’s genetically engineered Atlantic salmon was as nutritious as the farm-raised ones and was safe for consumption. AquaBounty developed a form of salmon that grows faster and is much more efficient in the
conversion of feed to protein, compared to conventional salmon. The approval comes with the condition that the salmon be raised only in two specific land-based, contained hatchery tanks in Canada and Panama, and not in the United States.
Tianhe-2: World’s powerful Supercomputer
Tianhe-2 has maintained its rank as the world’s most powerful supercomputer for the sixth consecutive time. Developed by China’s National University of Defense Technology and deployed at the National Supercomputer Center in Guangzhou, Tianhe-2, or Milky Way 2, has a performance of 33.86 petaflops per second (Pflop/s). It has held the title as the most powerful computer since June 2013. The Chinese supercomputer system can perform almost twice as fast as the Titan of the U.S. Department of Energy, the next on the list, which has a performance of 17.59 Pflop/s.
Oldest known stars found at the heart of Milky Way
Astronomers have discovered the oldest known stars near the centre of the Milky Waygalaxy, dating back to the time when the universe was just 300 million years old. The stars are surprisingly pure but contain material from an even earlier star, which died in an enormous explosion called hypernova.
The discovery and analysis of the nine pure stars challenges current theories about the environment of the early universe from which these stars formed. The stars have surprisingly low levels of carbon, iron and other heavy element, which suggests the first stars, might not have exploded as normal supernovae. Perhaps they ended their lives as hypernovae- poorly understood explosions
of probably rapidly rotating stars producing 10 times as much energy as normal supernovae.
