1. Newly discovered fish named
Scientists have named a small maroon and gold fish species after the U.S. President Barack Obama which was discovered 300 feet deep in the waters off Kure Atoll in the Pacific Ocean.
- The fish, of the genus Tosanoides, was named in honour of Obama for his commitment to protecting nature through the expansion of the Papahanaumokuakea Marine National Monument, researchers said.
- It was discovered in June this year during a research trip to Kure, the world’s northernmost atoll.
- Atolls ring-shaped reef, island, or chain of islands formed of corals.
2. GSLV-F05/INSAT 3DR
ISRO is all set to launch the GSLV-F05 carrying advanced weather satellite INSAT-3DR from the spaceport of Sriharikota on September eight. GSLV-F05/INSAT 3DR mission is scheduled to be launched on September 8 from Satish Dhawan Space Centre, Sriharikota.
- The previous launch by ISRO on Geosynchronous Satellite Launch Vehicle (GSLV) was launch of GSLV-D6 carrying communication satellite GSAT-6 on August 27, 2015.
- GSLV-F05 in its 10th flight would launch the 2,211 kg advanced weather satellite INSAT-3DR into Geostationary Transfer Orbit (GTO).
- INSAT-3DR will provide a variety of meteorological services to the country.
3. First LIGO lab outside U.S.
The Laser Interferometer Gravitational-wave Observatory (LIGO) project — that proved the existence of gravitational waves, a major breakthrough in science — is coming to India. Maharashtra’s Hingoli district has been chosen as the place for establishing the third laboratory for the experiment. A senior scientist with the Department of Science and Technology (DST) said, “Aundh in Hingoli district is a preferred site for the Ligo project.
- LIGO-India will also bring considerable opportunities in cutting edge technology for Indian industries as they will be engaged in the construction of the eight-kilometre-long beam tube at ultra-high vacuum on a levelled terrain.
- An agreement to set up the LIGO project was recently signed between the scientists from the U.S.’ National Science Foundation (NSF) with the India’s DAE and the DST.
4. Biodegradable energy harvester
A team of researchers at Jadavpur University has developed a biodegradable energy harvester – from raw fish scales – which could be tapped as a sustainable green energy source for next generation self-powered implantable medical devices. It also has the potential for personal portable electronics with reduced e-waste elements said the researchers.
- Fish scales, a by-product that is usually thrown away, contain collagen fibres that possess apiezoelectric property, which means that an electric charge is generated in them in response to mechanical stress.
- The researchers have synthesised flexible bio-piezoelectric nanogenerator (BPNG) from this bio-waste.
5. 2nd space lab
China successfully launched its second experimental space lab as part of an ambitious programme by the Communist giant to build a manned space station by 2022, the time when US-led International Space Station expected to go out of service. The Tiangong-2 space lab was successfully launched from the Jiuquan Satellite Launch Centre in northwestern China’s Gobi Desert.
- The mission is complete success and the space lab reached its designated orbit, the official said.
- China’s manned space program has now entered a new phase of application and development.
- In a cloud of brown smoke, Tiangong-2 roared into the air underneath a mid-autumn full moon from the Jiuquan Satellite Launch Center on the back of a Long March-2F rocket, trailing a vast volume of flame.
6. Long range surface-to-air missile test fired
In a bid to galvanise its air defence capabilities, India on 20 September 2016 successfully test fired a new, long range surface-to-air missile jointly developed with Israel from a defence base off Odisha coast. The long range missile, a product of a joint venture betweenIndia and Israel, was test launched from a mobile launcher at the Integrated Test Range (ITR) in Chandipur.
- The trial was successful and some more rounds of test are expected to be conducted shortly, the DRDO scientist said.
- Apart from the missile, the system includes a Multi-Functional Surveillance and Threat Alert Radar (MF STAR) for detection, tracking and guidance of the missile.
- The missile along with MF-STAR would provide the users the capability to neutralise any aerial threats.
7. Tool to measure disasters loses
The government has developed a scientific tool based on a UN model which will use satellite imagery and on-ground assessments to measure direct and indirect damages besides the ‘opportunity cost’ lost due to disasters. This will help the Centre make a more accurate and scientific assessment of relief and reconstruction packages for disaster-hit regions, and not be dependent on the arbitrary claims made by states.
- India’s estimated economic losses are pegged at around $10 billion annually on account of disasters — almost equal to what the country spends on education and twice the amount it spends on healthcare every year.
- Globally, climate change resulted in economic losses of around $300 billion annually, according to the UN Office for Disaster Risk Reduction’s (UNISDR) global assessment report-2015.
- The scientific tool, called the Post-Disaster Need Assessment (PDNA), has been developed by the National Institute of Disaster Management (NIDM), a part of the home ministry. It is ready for trials and a pilot will run in a calamity-hit region.
8. World’s largest radio telescope
China commissioned the world’s largest radio telescope, a 4,450-panel reflector as large as 30 football pitches, which can help in better understanding the origin of the universe and boost global hunt for extraterrestrial life. Hundreds of astronomers and astronomy enthusiasts witnessed the official launch of the 500-meter Aperture Spherical Telescope’s (FAST) mission in a karst valley in Pingtang County in Guizhou Province.
- Work on the nearly 1.2 billion-yuan (USD 180 million) project started in 2011, 17 years after it was proposed by Chinese astronomers.
- The installation of the telescope’s main structure — a 4,450-panel reflector as large as 30 football pitches was built at unique valley in southwest China where over 8,000 people have been evacuated as it requires quiet atmosphere.
- FAST will require radio silence within a 5-kms radius.
9. World’s first three-parent baby born
The world’s first three-parent baby has been born in Mexico with the help a controversial new fertility technique that incorporates DNA from three people, and is reported to be healthy at five months of age. The ‘three-parent’ technique allows parents with rare genetic mutations to have healthy babies. The boy’s mother carries genes for Leigh syndrome, a fatal disorder that affects the brain, muscles and nerves of developing infants. Genes for the disease reside in DNA in the mitochondria, which provide energy for our cells.
- The parents of the baby, a Jordanian couple, had been trying to start a family for almost 20 years. Ten years after they married, the woman became pregnant, but it ended in the first of four miscarriages.
- In 2005, the couple gave birth to a baby girl. Their daughter was born with Leigh syndrome, and died aged six. The couple’s second child had the same disorder, and lived for 8 months, the ‘New Scientist’ reported. The couple sought out the help of John Zhang and his team at the New Hope Fertility Centre in New York City.
10. PSLV-C35 to inject eight satellites
In its first multi-orbital launch, India’s workhorse PSLV will on 26 September 2016 inject eight different satellites, including the country’s weather satellite SCATSAT-1 and five from other nations, into two different orbits. The countdown for the launch of SCATSAT-1 for ocean and weather related studies along with seven other satellites, is progressing satisfactorily, a top ISRO official said.
- India’s workhorse Polar Satellite Launch Vehicle, PSLV-C35, which will be launched from the First Launch Pad of Satish Dhawan Space Centre SHAR, Sriharikota at 9:12 a.m. on 26 September 2016, will carry the 371 kg SCATSAT-1 along with seven other satellites, including from the US and Canada.
- The total weight of all the eight satellites on-board PSLV C35 is about 675 kg.
- PSLV C-35 will be putting the satellites in two different orbits.
