Made in India interceptor missile shoots down one from multiple simulated targets
In a major breakthrough for Defence Research and Development Organisation (DRDO), made in India interceptor missile capable of killing incoming enemy missiles in endo atmospheric region at low altitude shot down a target from multiple simulated targets.
For the first time the missile was fired against multiple targets simulated electronically by the mission team comprising officials from the Indian Army. The missile attacked one after choosing it from a bunch of targets.
The supersonic ballistic interceptor missile dubbed as Advance Air Defence (AAD) was fight tested from Abdul Kalam Island, a part of Integrated Test Range (ITR) off Odisha coast.
Long range radar and multi-function fire control radar located far away successfully detected the missile from take-off and tracked it through its entire path. The total trajectory of the incoming missile was continuously estimated by the guidance computer and subsequently the AAD missile was launched at an appropriate time to counter and kill the target missile.
The Fibre Optic Gyro (FOG) based INS in interceptor, on-board computers, guidance systems, actuation systems and the critical Radio Frequency (RF) seekers used for the terminal phase have also performed excellently.

Chinese scientists have created the first single-chromosome yeast
Chinese scientists claimed to have created the first single-chromosome yeast while not affecting the majority of its functions, a breakthrough that could help in furthering research related to aging and diseases in humans.
Brewer's yeast, one-third of whose genome is said to share ancestry with humans, has 16 chromosomes. However, Chinese scientists have managed to fit nearly all its genetic material into just one chromosome while not affecting the majority of its functions, according to a paper released yesterday on the website of the journal Nature.
Qin Zhongjun, a molecular biologist at the Centre for Excellence in Molecular Plant Sciences of the Shanghai Institute of Plant Physiology and Ecology under the Chinese Academy of Sciences, and his team used CRISPR-Cas9 genome-editing to create a single-chromosome yeast strain. Yeast is a type of eukaryote, which also includes humans, plants, and animals. Humans have 46 chromosomes, whereas male jack jumper ants have just one. It seems that the number of chromosomes of a eukaryote has no correlation with the amount of genetic information they possess.

World’s first mission to touch the Sun lifts off: NASA
NASA’s Parker Solar Probe, mankind’s first mission to ‘touch’ the Sun, has been launched on a seven-year long journey to unlock the mysteries of our star’s fiery outer atmosphere and its effects on space weather.
Liftoff took place from Space Launch Complex 37 at Cape Canaveral Air Force Station in the US early.
The launch of the United Launch Alliance Delta IV Heavy rocket carrying the spacecraft was scrubbed yesterday due to a violation of a launch limit, resulting in a hold.
The car-sized spacecraft will travel directly into the Sun’s atmosphere, about four million miles from its surface - and more than seven times closer than any spacecraft has come before, thanks to its innovative Thermal Protection System. The USD 1.5 billion mission will perform the closest-ever observations of a star when it travels through the Sun’s outer atmosphere, called the corona.
It will make 24 passes through the corona during its seven-year mission. The mission will rely on measurements and imaging to revolutionise our understanding of the corona and how processes there ultimately affect near-Earth space.

India’s second lunar mission to land on moon with lander, rover: ISRO
India will launch its second lunar mission on January 3 next year which will land on the moon with a lander and rover.
The Rs 800-crore lunar mission named ''Chandrayaan-2'' comes over a decade after India went up to the lunar orbit on November 8, 2008 after the ''Chandrayaan-1'' launch on October 22 onboard a Polar Satellite Launch Vehicle (PSLV) rocket from the spaceport in Sriharikota in Andhra Pradesh.
The 3,890-kg Chandrayaan-2, which will be launched onboard the Geosynchronous Satellite Launch Vehicle (GSLV) Mk-3, will orbit around the moon and study its lunar conditions to collect data on its topography, mineralogy and exosphere.
A lander with rover which will separate from the spacecraft will orbit the moon, and then gradually descend on the lunar surface at a designated spot. The rover’s instruments will observe and study the lunar surface.
The lander has been named “Vikram” as a tribute to the pioneer of India’s space programme and former ISRO chairman (1963-71), Vikram Sarabhai.
This is the first time India will have a rover landing on the moon nearly 50 years after American astronaut Neil Armstrong walked on the eerie lunar surface in 1969.
The Indian space agency, which was eyeing at the second lunar mission this year, has had to make design and functional changes to Chandrayaan-2, causing the delay and pushing the mission to January next year. For its Chandrayaan-1, ISRO had carried a moon impact probe vehicle to crash land on the surface from the lunar orbit.

Aditya-L1 is India's first mission to study the Sun
NASA launched its Parker Solar probe in space, in order to study the Sun’s atmosphere, known as the corona. The $1.5 billion probe will be the closest man-made device to ever reach the Sun in the history of space exploration. Its mission is to mostly study and track solar winds emitted by Corona, which is an aura of plasma that surrounds the Sun. Now, India’s ambitious space agency ISRO (Indian Space Research Organisation) is also getting ready to launch its very own probe to study the Sun called the Aditya-L1.
The satellite is being targeted to launch sometime between 2019 – 2020. Initially the mission was dubbed as the Aditya-1 and was only said to carry a payload of 400kg, which consisted of the Visible Emission Line Coronagraph. The satellite was planned to be launched in an 800 km low earth orbit. However, the agency then realized that a satellite placed in the halo orbit around the Lagrangian point 1 (L1) of the Sun-Earth system has an advantage of continuously observing the Sun without being affected by any occultation or eclipse.

International team of scientists including 18 Indian scientists decode complex wheat genome
In a major scientific breakthrough, a team of international researchers, including 18 from India decoded the wheat genome, considered insurmountable so far. The information generated will help to identify genes controlling complex agronomic traits such as yield, grain quality, resistance to diseases and pests, as well as tolerance to drought, heat, water logging and salinity.
The DNA sequence has been ordered and it represents the highest quality genome sequence generated to date for the bread wheat. The reference genome covers 94% (14.5 Gb) of the entire wheat genome. The bread wheat has a complex hexaploid genome which is 40 times larger than that of the rice genome and 5 times larger than the human genome.
The research article– authored by more than 200 scientists from 73 research institutions in 20 countries. A team of 18 Indian scientists co-authoring this paper, led by Dr. Kuldeep Singh at Punjab Agricultural University (PAU) Ludhiana, Professor J.P. Khurana at the University of Delhi South Campus, and Professor Nagendra Singh at ICAR-National Research Centre on Plant Biotechnology, New Delhi, contributed to the decoding of Chromosome 2A of the wheat genome. This project was financially supported by the Department of Biotechnology, Government of India.

Researchers develop world's first-ever 4D printing for ceramics
While the world is still trying to digest the concept of 3D printing, researchers have developed the world's first-ever 4D printing for ceramics, which are mechanically robust and can have complex shapes. Ceramic has a high melting point, so it is difficult to use conventional laser printing to make ceramics. The existing 3D-printed ceramic precursors, which are usually difficult to deform, also hinder the production of ceramics with complex shapes.
To overcome these challenges, scientists developed a novel 'ceramic ink', which is a mixture of polymers and ceramic nanoparticles. These flexible and stretchable ceramic precursors allow complex shapes, such as origami folding, to made using proper heat treatment.
4D printing is conventional 3D printing combined with the additional element of time as the fourth dimension, where the printed object can re-shape or self-assemble itself over time with external stimuli, such as mechanical force, temperature, or a magnetic field.

Chandrayaan-I data confirms presence of ice on Moon
Scientists have found frozen water deposits in the darkest and coldest parts of the Moon’s Polar Regions using data from the Chandrayaan-I spacecraft that was launched by India ten years ago.
With enough ice sitting at the surface - within the top few millimetres - water would possibly be accessible as a resource for future expeditions to explore and even stay on the Moon, and potentially easier to access than the water detected beneath the Moon’s surface.
The ice deposits are patchily distributed and could possibly be ancient, according to the study published in the journal PNAS. At the southern pole, most of the ice is concentrated at lunar craters, while the northern pole’s ice is more widely, but sparsely spread.
Scientists used data from NASA’s Moon Mineralogy Mapper (M3) instrument to identify three specific signatures that definitively prove there is water ice at the surface of the Moon. M3, aboard the Chandrayaan-1 spacecraft, launched in 2008 by the Indian Space Research Organisation (ISRO), was uniquely equipped to confirm the presence of solid ice on the Moon.

New wireless, 'in-body GPS' system can track tumours
Scientists have developed a wireless 'in-body GPS' system that can pinpoint the location of ingestible implants and track tumours inside the body.
In animal tests, the team demonstrated that the system dubbed ReMix can track the implants with centimetre-level accuracy. Similar implants could be used to deliver drugs to specific regions in the body.
To test ReMix, researchers from Massachusetts Institute of Technology (MIT) and Massachusetts General Hospital (MGH) in the US first implanted a small marker in animal tissues.

New antibiotic candidate identified in human body
Scientists have found compounds in the human body with potent antimicrobial effects that may lead to the development of new drugs and help leverage mankind's fight against superbugs.
The human body produces many antimicrobial peptides that help the immune system fend off infection. Scientists are hoping to harness these peptides as potential antibiotics.
Researchers from Massachusetts Institute of Technology (MIT) in the US and the University of Naples Federico II in Italy found that fragments of the protein pepsinogen, an enzyme used to digest food in the stomach, can kill bacteria such as Salmonella and E coli.

Indian-American scientist finds simple way to predict IBD
An Indian-American scientist has identified as many as 50 protein biomarkers that can non-invasively detect inflammatory bowel disease (IBD) - a gut disorder that leads to diarrhoea, abdominal cramps, and weight loss.
Chander Mohan, a professor at University of Houston in the US, received a USD 347,490 grant from the Crohn's & Colitis Foundation of America.
Along with IBD expert Subra Kugathasan, a gastroenterologist at Emory University in the US, Mohan is examining stool protein biomarkers that indicate the disease.
IBD occurs when the body's immune system fights its intestinal cells. Two of the most common types are Crohn's disease and ulcerative colitis, both of which cause inflammation in the digestive tract.

Lithium-ion batteries that will not catch fire has been developed
Scientists have developed novel lithium-ion batteries with components that harden on impact, preventing them from catching fire and causing injuries to users. Lithium-ion batteries commonly used in consumer electronics are notorious for bursting into flame when damaged or improperly packaged. These incidents occasionally have grave consequences, including burns, house fires and at least one plane crash. Inspired by the property of some liquids that solidify on impact, researchers have developed a practical and inexpensive way to help prevent these fires.
To make these batteries safer, some researchers instead use a nonflammable, solid electrolyte. However, these solid-state batteries require significant retooling of the current production process.

Among the more recent innovations that DBS has launched is POSB Smart Buddy, a savings and payments programme where children use smartwatches issued by the bank. Parents can allocate pocket money for their children and track their spending with a mobile app paired with the watch.
While the bank's digital transformation is more visible in customer-facing roles, Mr Gupta noted that its support functions, such as marketing and communications, human resource and audit, are also being innovated.

New technique developed to detect early-stage cancer tumour cells in blood, researchers claim
Researchers at an Australian university have claimed that a "new technique" to detect early-stage cancer tumour cells in the blood using a malaria protein has been developed.
The University of New South Wales (UNSW), Sydney and the University of Copenhagen jointly worked on the research led by the Australian varsity.
The findings of Heeschen and his team were published recently in the journal 'Nature Communications'.
According to the research, the new method can be used "more broadly to diagnose cancer" as it is not limited by cancer type. It also means all that is needed for a cancer diagnosis is a blood sample.
Heeschen thinks the new technique could be available in the market within two years if a bio-diagnostic company were to take it on.

NASA set to launch Ice, Cloud and land Elevation Satellite-2 (ICESat-2) to track Earth’s melting ice
NASA is set to launch the most advanced laser instrument of its kind in to the space next month, to measure the changes in the heights of Earth’s polar ice in unprecedented detail.
The Ice, Cloud and land Elevation Satellite-2 (ICESat-2) will measure the average annual elevation change of land ice covering Greenland and Antarctica to within the width of a pencil, capturing 60,000 measurements every second.
The new observational technologies of ICESat-2 - a top recommendation of the scientific community in NASA’s first Earth science decadal survey - will advance our knowledge of how the ice sheets of Greenland and Antarctica contribute to sea level rise.
ICESat-2 - which is scheduled to be launched represents a major technological leap in our ability to measure changes in ice height. Its Advanced Topographic Laser Altimeter System (ATLAS) measures height by timing how long it takes individual light photons to travel from the spacecraft to Earth and back.
ATLAS will fire 10,000 times each second, sending hundreds of trillions of photons to the ground in six beams of green light. The roundtrip of individual laser photons from ICESat-2 to Earth’s surface and back is timed to the billionth of a second to precisely measure elevation.

India's first manned space mission, Gaganyaan, to send three persons for 5-7 days
India’s first manned space flight - Gaganyaan - will send three humans into space for five to seven days and the spacecraft will be placed in a low earth orbit of 300-400 k m from the earth’s surface.
India’s first human space flight to be launched before its 75th Independence Day could be led by a man or even a woman.

Jupiter’s Great Red Spot reveals signs of water: NASA
NASA scientists peering deep inside Jupiter’s Great Red Spot - a storm that has been raging on the planet for over 350 years - have detected signs of water above the planet’s deepest clouds.

The pressure of the water combined with their measurements of another oxygen-bearing gas, carbon monoxide, imply that Jupiter has two to nine times more oxygen than the Sun. The findings, published in the Astronomical Journal, support theoretical and computer-simulation models that have predicted abundant water on Jupiter.
The Great Red Spot is full of dense clouds, which makes it hard for electromagnetic energy to escape and teach astronomers anything about the chemistry within.

New tech can predict fatal heart attacks: Study
A new technology that can flag patients at the risk of deadly heart attacks years in advance has been developed by scientists, including one of Indian origin.
Created by researchers at the University of Oxford in the UK and colleagues, the technology analyses computed tomography (CT) images of the fat surrounding the arteries to detect the inflamed plaques that can cause heart attacks.
It uses a new biomarker, called the Fat Attenuation Index (FAI), which has been tested for the first time in a large study published in The Lancet journal.
Heart attacks are usually caused by inflamed plaques in the coronary artery causing an abrupt blockage of blood getting to the heart.
