News 1 - NASA Satellite Finds Unreported Sources of Toxic Air Pollution
Scientists at NASA, Environment and Climate Change Canada, and two universities have located 39 unreported and major human-made sources of toxic sulfur dioxide emissions. The 39 unreported emission sources, found in the analysis of satellite data from 2005 to 2014, are clusters of coal-burning power plants, smelters, oil and gas operations found notably in the Middle East, but also in Mexico and parts of Russia.
Sulphur dioxide is a known health hazard and cause of acid rain.
News 2 - Scientists develop “Bionic Leaf” that turns sunlight into liquid fuel
Professor Daniel Nocera at Harvard University and Pamela Silver, Professor of Biochemistry and Systems Biology at Harvard Medical School have co-created a “bionic leaf” which uses the sun’s energy to split water molecules and hydrogen-eating bacteria to produce liquid fuels.
The new system can convert solar energy to biomass with 10% efficiency. Its efficiency is much higher than the 1% seen in the fastest growing plants. It has been dubbed as "bionic leaf 2.0".
News 3 - THOR – World's first 3D-printed aircraft revealed at Aerospace Exhibition
Test of High-tech Objectives in Reality, world's first 3D-printed aircraft unveiled at International Aerospace Exhibition in Schoenefe on 1st June 2016. It appears like a large, white model airplane, weighs 21 kgs and 13 feet long. Airbus and Boeing are using 3D printing to make parts for their huge passenger jets the A350 and B787 Dreamliner.
The 3D printed pieces have the benefit of no tools requirement and that they can be made very quickly. 3D printing also ensures ecological benefits as lighter jets use less fuel and expells out fewer pollutants. It brings big cost reductions on parts manufacturing.
News 4 - ESA's LISA Pathfinder mission paves way to detect gravitational wave
LISA Pathfinder has successfully tested a key technology needed to build a space-based observatory for detecting gravitational waves. The mission is led by the European Space Agency (ESA) with contributions from NASA.
It has opened the doors to the development of a large space observatory capable of detecting gravitational waves emanating from a wide range of exotic objects in the Universe. Gravitational waves, predicted by Albert Einstein a century ago, are oscillations in the fabric of space-time, moving at the speed of light and caused by the acceleration of massive objects.

News 6 - Iceland scientists turn CO2 into Stone under CarbFix Project
Researchers working in Iceland have discovered a new way to trap the greenhouse gas carbon dioxide (CO2) deep underground: by changing it into rock. The CarbFix Project has converted 95 percent of the CO2 emissions from a geothermal plant into solid carbonate minerals. The technique has to clear some high hurdles to become commercially viable.
Dozens of pilot projects around the world have sought to test carbon capture and storage (CCS) as a way of curbing CO2 emissions from power plants.

News 14 - ISRO gears up to test an Indigenously Developed Scramjet Engine
Riding high on the success of the technology demonstration flight of its Reusable Launch Vehicle (RLV- TD) last month, ISRO is gearing up to test an indigenously developed scramjet engine based on air-breathing propulsion. The test flight of the scramjet engine is scheduled to take place from the Satish Dhawan Space Centre at Sriharikota in July. Called as Advanced Technology Vehicle (ATV), the test platform will comprise a scramjet engine hitched to a two-stage sounding rocket (RH- 560).
The vehicle has been characterized and being fabricated at the VSSC (Vikram Sarabhai Space Center) and the ISRO Propulsion Complex, Mahendragiri. The test is expected to help ISRO to achieve good thrust value with the scramjet engine as maintaining combustion in hypersonic conditions poses technical challenges.

News 18 - Australian Great Barrier Reef Rodent is the First Mammal Made Extinct by Human-Driven Climate Change
The Bramble Cay Melomys, a rodent which is found only on a tiny island on the Great Barrier Reef of Australia has been declared extinct by scientists. It is the first mammal known to be wiped out by human-induced climate change. The long tailed rodent looked like a small brown rat was known to have lived only on Bramble Cay, a hump of coral just 340 meters long and 150 meters wide that juts out three meters or less above the water between Queensland in Australia and Papua New Guinea.
This is the first documented extinction of a mammal because of climate change. The key factor responsible for the death of the Bramble Cay Melomys is high tides and surging seawater, which has traveled inland across the island.
News 19: Chinese Supercomputer, Sunway TaihuLight declared as the World’s Fastest Supercomputer
A new Chinese supercomputer, Sunway- TaihuLight, built using domestic chip technology has been declared as the world's most powerful and the fastest supercomputer. It is developed by the National Research Centre of Parallel Computer Engineering and Technology (NRCPC) and is built entirely using processors designed and made in China.
It topped the list of the Top 500 supercomputers with 93 quadrillion calculations per second. With processing capacity of 125.436 petaflops (PFlops) per second, it is the first supercomputer to achieve speeds in excess of 100 PFlops. In 2001, there were no Chinese supercomputers in the world's top 500 ranking. Now, there are 167 — more than the US, which has 165 entries.
The fastest Supercomputer in India is SERC at IISc Bangalore with a speed of 0.90 PFLOP/S and ranked 109 in the list.
News 20: NASA unveils X-57 Hybrid Electric Research Plane
The National Aeronautics and Space Administration (NASA) unveiled the X-57 Hybrid Electric Research Plane nicknamed as Maxwell. With 14 electric motors turning propellers and all of them integrated into a uniquely-designed wing, NASA will test new propulsion technology using this plane.
“Maxwell” will be powered only by batteries, eliminating carbon emissions. The X-57’s electric propulsion technology is expected to significantly decrease aircraft noise, making it less annoying to the public.
News 21: Scientists develop new bio-ink for 3D printing with stem cells
Scientists at the University of Bristol have developed a new kind of bio-ink, which could eventually allow the production of complex tissues for surgical implants. The new stem cell-containing bio ink allows 3D printing of living tissue, known as bio-printing.
The bio-ink contains two different polymer components: a natural polymer extracted from seaweed, and a sacrificial synthetic polymer used in the medical industry. The synthetic polymer causes the bio-ink to change from liquid to solid when the temperature is raised, and the seaweed polymer provides structural support when the cell nutrients are introduced.
News 22: CSIR launches anti diabetic Ayurvedic drug BGR–34
The Council for Scientific and Industrial Research (CSIR) has launched BGR-34, an anti-diabetic Ayurvedic drug designed for type 2 Diabetes mellitus. BGR-34 is developed jointly by National Botanical Research Institute (NBRI) and Central Institute for Medicinal and Aromatic Plants (CIMAP).
The BGR-34 has been economically priced at 5 rupees per tablet as compared to latest DPP4 inhibitors globally. While the modern diabetes drugs are known for side-effects and toxicity, BGR-34 works by controlling blood sugar and limiting the harmful effects of other drugs.
News 23: NASA tests a Deep Space Rocket Booster ahead of the 2018 space mission
NASA performed its second and last test-fire of a rocket booster for the Space Launch System (SLS) at Orbital ATK's test facilities in Promontory, Utah. NASA has described the SLS as the "world's most powerful rocket." This was the last full-scale test for the booster before SLS’s first un-crewed test flight with NASA’s Orion spacecraft in late 2018.
When completed, two five-segment boosters and four RS-25 main engines will power SLS on deep space missions. They will provide more than 75 percent of the thrust needed for the rocket and Orion spacecraft to escape Earth’s gravitational pull.
