    China’s use of ‘Microwave Weapons’

    Prelims Only | Security Issues | Mains Paper 3: Border Area Security Challenges

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Microwave weapons

    Mains level: Not Much

    The Indian Army has rejected a report in the British daily newspaper which claimed that the Chinese army had used “microwave weapons” to drive Indian soldiers away from their positions in eastern Ladakh.

    The use of non-lethal weapons for violence and mob control is a contested issue. Can you suggest some alternatives to it apart from the use of water cannon and teargas?

    What are “Microwave Weapons”?

    • Microwave weapons are supposed to be a type of direct energy weapons, which aim highly focused energy in the form of sonic, laser, or microwaves, at a target.
    • It uses a focussed beam of high-frequency electromagnetic radiation to heat the water in a human target’s skin, causing pain and discomfort.
    • In a microwave oven, an electron tube called a magnetron produces electromagnetic waves (microwaves) that bounce around the metal interior of the appliance, and are absorbed by the food.
    • The microwaves agitate the water molecules in the food, and their vibration produces heat that cooks the food.
    • Food with high water content cooks faster in a microwave often than drier foods.

    Which countries have these “microwave weapons”?

    • A number of countries are thought to have developed these weapons to target both humans and electronic systems.
    • According to a report, China had first put on display its “microwave weapon”, called Poly WB-1, at an air show in 2014.
    • The United States has also developed a prototype microwave-style weapon, which it calls the “Active Denial System”.

    How dangerous are these weapons?

    • Concerns have been raised on whether they can damage the eyes, or have a carcinogenic impact in the long term.
    • It is not clear yet how China intends to use such a weapon, and whether it can kill or cause lasting damage to human targets.

    What is mRNA vaccine?

    Prelims Only | Science Tech | Mains Paper 3: Awareness in various sc and tech fields

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: mRNA

    Mains level: Vaccination challenges for coronavirus

    The Moderna and Pfizer vaccines which recently announced their success use the same technology, based on messenger RNA, or mRNA.

    Try this PYQ first:

    Q.‘RNA interference (RNAi)’ technology has gained popularity in the last few years. Why?

    1. It is used in developing gene silencing therapies.
    2. It can be used in developing therapies for the treatment of cancer.
    3. It can be used to develop hormone replacement therapies.
    4. It can be used to produce crop plants that are resistant to viral pathogens.

    Select the correct answer using the code given below:

    (a) 1, 2 and 4

    (b) 2 and 3

    (c) 1 and 3

    (d) 1 and 4 only

    What is mRNA?

    • Messenger RNA (mRNA) is a single-stranded RNA (Ribo Nucleic Acid) molecule that is complementary to one of the DNA strands of a gene.
    • The mRNA is an RNA version of the gene that leaves the cell nucleus and moves to the cytoplasm where proteins are made.
    • During protein synthesis, an organelle called a ribosome moves along the mRNA, reads its base sequence, and uses the genetic code to translate each three-base triplet, or codon, into its corresponding amino acid.

    What is the mRNA vaccine?

    • Such vaccines make use of the messenger RNA molecules that tell the body’s cells what proteins to build.
    • The mRNA, in this case, is coded to tell the cells to recreate the spike protein of the coronavirus SARS-CoV-2, which causes Covid-19.
    • It is the spike protein — which appears as spikes on the surface of the coronavirus — that initiates the process of infection; it allows the virus to penetrate cells, after which it goes on to replicate.
    • A coronavirus vaccine based on mRNA, once injected into the body, will instruct the body’s cells to create copies of the spike protein.
    • In turn, this is expected to prompt the immune cells to create antibodies to fight it.
    • These antibodies will remain in the blood and fight the real virus if and when it infects the human body.

    Back2Basics: Ribo Nucleic Acid (RNA)

    • RNA is an important biological macromolecule that is present in all biological cells.
    • It is principally involved in the synthesis of proteins, carrying the messenger instructions from DNA, which itself contains the genetic instructions required for the development and maintenance of life.
    • In some viruses, RNA, rather than DNA, carries genetic information.
    • The type of RNA dictates the function that this molecule will have within the cell.
    • Aside from the coding region of messenger RNA (mRNA) molecules that will be translated into proteins, other cellular RNA elements are involved in different processes.

    Places in news: Tristan da Cunha

    Prelims Only | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Map reading: Tristan Da Cunha

    Mains level: Not Much

    The isolated UK Overseas Territory of Tristan da Cunha, the world’s most remote human settlement, has been declared the largest fully protected marine reserves in the Atlantic Ocean at 687,000 square kilometres.

    Note the location of Tristan da Cunha Islands in the Atlantic.

    Tristan da Cunha

    • Tristan da Cunha, which is inhabited by less than 300 humans is a small chain of islands over 6,000 miles from London in the South Atlantic and the water around the islands are considered to be the richest in the world.
    • The mountainous archipelago is home to tens of millions of seabirds and several unique land birds that are comparable to the Galapagos island finches.
    • The island group is also home to the World Heritage Site of Gough and Inaccessible Islands, which is one of the most important seabird islands in the world.

    Significance of protection

    • After joining the UK’s Blue Belt Programme, it will become the largest no-take zone in the Atlantic and the fourth largest on the planet.
    • This will close over 90 per cent of their waters to harmful activities such as bottom-trawling fishing, sand extraction and deep-sea mining.
    • The almost 700,000 square kilometres of the Marine Protection Zone (MPZ) is almost three times the size of the UK and will safeguard the future of sevengill sharks, Yellow-nosed albatrosses and rockhopper penguins.
    • MPZs involve the management of certain natural areas for biodiversity conservation or species protection and are created by delineating zones with permitted and non-permitted areas within that zone.

    Leonid Meteor Shower

    Prelims Only | Science Tech | Mains Paper 1: Geographical Features & Their Location

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Meteor terminology

    Mains level: Not Much

    The Leonid meteor showers are currently making their yearly appearance and will reach their peak in India on November 17 and 18.  In August this year, there was another meteor called Perseids Shower.

    Try this question from CSP 2014:

    Q.What is a coma, in the content of astronomy?

    (a) Bright half of material on the comet

    (b) Long tail of dust

    (c) Two asteroids orbiting each other

    (d) Two planets orbiting each other

    What is Leonid Meteor Shower?

    • Meteor showers are named after the constellation they appear to be coming from.
    • The Leonids originate from the constellation Leo the Lion– the groups of stars which form a lion’s mane.
    • They emerge from the comet Tempel-Tuttle, which requires 33 years to revolve once around the Sun.
    • These meteors are bright and among the fastest moving– travelling at speeds of 71 km per second.
    • During this year’s showers, peaks of around 10 to 15 meteors are expected to be seen every hour.
    • The Leonid showers include fireballs– bright and large meteors than can last longer than average meteors, and “earthgazers”– meteors which appear close to the horizon with colourful and long tails.

    What is a meteor shower?

    • On its journey around the Sun, the Earth passes through large swathes of cosmic debris.
    • The debris is essentially the remnants of comets — great frigid chunks of matter that leave behind dirty trails of rocks and ice that linger long after the comets themselves have passed.
    • As the Earth wades through this cloud of comet waste, the bits of debris create what appears from the ground to be a fireworks display in the sky — known as a meteor shower.
    • Several meteor showers can be seen around the year. According to NASA, over 30 meteor showers occur annually and are observable from the Earth.

    Gujarat Maritime Cluster Project at GIFT City

    Prelims Only | Economics | Mains Paper 3: Infrastructure: Energy, Ports, Roads, Airports, Railways Etc.

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Gujarat Maritime Cluster

    Mains level: Need for a Maritime Cluster in India

    The Gujarat Maritime Cluster coming up in the GIFT (Gujarat International Finance Tec-City) City at Gandhinagar will be a dedicated system to address logistics of ports and seaways.

    Try answering this:

    Q.What do you mean by Central Business Districts? How it is different from a Special Economic Zone (SEZ)?

    What is a Maritime Cluster?

    • The concept of the maritime cluster is new to India, but these clusters have been driving some of the most competitive ports of the world like Rotterdam, Singapore, Hong Kong, Oslo, Shanghai, and London.
    • Simply put, a maritime cluster is an agglomeration of firms, institutions, and businesses in the maritime sector that are geographically located close to each other.

    Gujarat Maritime Cluster

    • While the project was conceptualized back in 2007, it received in-principle approval from the state government only in 2015.
    • The Gujarat Maritime Board (GMB), a nodal agency of the Gujarat government, has been trying to develop such a cluster at GIFT City in the state capital Gandhinagar.
    • This cluster will initially consist of Gujarat-based shipping lines, freight forwarders, shipping agents, bunker suppliers, stevedores, and shipbrokers with chartering requirements.
    • In the second stage, the cluster would attempt to bring Indian ship owners, ship operators, Indian charterers and technical consultants scattered in cities like Mumbai, Chennai, and Delhi to Gujarat.
    • Thereafter it would target to attract global players in the maritime sphere.

    Need for a maritime cluster

    • This project will try to bring back businesses that have migrated over the years to foreign locations due to the absence of the right ecosystem in the country.
    • Gujarat has a lot of ports and handles 40 per cent of the country’s cargo, but it does not target the entire value chain.
    • Since we didn’t have the ecosystem, a lot of Indian companies have moved to foreign locations. For instance, Adani Group has the biggest port in Gujarat, but for their chartering needs, they are based out of Dubai.

    Back2Basics: GIFT City, Gandhinagar

    • GIFT city is India’s first operational smart city and international financial services centre (much like a modern IT park).
    • The idea for GIFT was conceived during the Vibrant Gujarat Global Investor Summit 2007 and the initial planning was done by East China Architectural Design & Research Institute (ECADI).
    • Currently approximately 225 units/companies are operational with more than 12000 professionals employed in the City.
    • The entire city is based on concept of FTTX (Fibre to the home / office).The fiber optic is laid in fault tolerant ring architecture so as to ensure maximum uptime of services.
    • Every building in GIFT City is an intelligent building. There is piped supply of cooking gas. India’s first city-level DCS (district cooling system) is also operational at GIFT City.

    SpaceX-NASA’s Crew-1 Mission

    Prelims Only | Science Tech | Mains Paper 3: Awareness in various sc and tech fields

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Crew-1 Mission

    Mains level: Manned mission to space

    SpaceX’s Crew Dragon spacecraft will lift off carrying a crew of four people to the International Space Station (ISS) on a six-month-long mission.

    What is the Crew-1 Mission?

    • The mission is part of NASA’s Commercial Crew Program, whose objective is to make access to space easier in terms of its cost.
    • This will carry four astronauts on NASA missions, maintaining a space station crew of seven to maximize time dedicated to scientific research on the orbiting laboratory.
    • With this, the cargo and crew can be easily transported to and from the ISS, enabling greater scientific research.
    • At the ISS, the crew will join the members of Expedition 64, the space station crew currently in residence at the ISS.

    Mission goals

    • The goals of the mission are the same as that of Expedition 1 that lifted off 20 years ago.
    • NASA has called both of these ISS missions “historic”.
    • At the ISS, the Crew-1 team will join members of Expedition 64 and conduct microgravity studies and deliver new science hardware to ISS.
    • Once in orbit, NASA astronauts will collect samples to provide data to scientists back on Earth so that they can continue to study how dietary changes affect his body.
    • The crew will also study the effects of dietary improvements on immune function and the gut microbiome and how those improvements can help crews adapt to spaceflight.

    The term micro-g environment is more or less synonymous with the terms weightlessness and zero-g, but with an emphasis on the fact that g-forces are never exactly zero—just very small.

    Thirty Metre Telescope (TMT)

    Prelims Only | Science Tech | Mains Paper 3: Awareness in various sc and tech fields

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Thirty Metre Telescope

    Mains level: Not Much

    With regime change in the US, hopes have been raised for the Thirty Meter Telescope (TMT) in Hawaii. India is one of the partners in the ambitious next-generation observatory project along with the US, Canada, China and Japan.

    Try this PYQ:

    Q.“Event Horizon” is related to:

    (a) Telescope

    (b) Black hole

    (c) Solar glares

    (d) None of the above

    Thirty Metre Telescope

    • The TMT is a proposed astronomical observatory with an extremely large telescope (ELT) that has become the source of controversy over its planned location on Mauna Kea on the island of Hawaii.
    • It is being built by an international collaboration of government organisations and educational institutions, at a cost of $1.4 billion.
    • “Thirty Metre” refers to the 30-metre diameter of the mirror, with 492 segments of glass pieced together, which makes it three times as wide as the world’s largest existing visible-light telescope.
    • The larger the mirror, the more light a telescope can collect, which means, in turn, that it can “see” farther, fainter objects.
    • It would be more than 200 times more sensitive than current telescopes and would be able to resolve objects 12 times better than the Hubble Space Telescope.

    Utility of the telescope

    • One of its key uses will be the study of exoplanets, many of which have been detected in the last few years, and whether their atmospheres contain water vapour or methane — the signatures of possible life.
    • For the first time in history, this telescope will be capable of detecting extraterrestrial life.
    • The study of black holes is another objective.
    • While these have been observed in detail within the Milky Way, the next galaxy is 100 times farther away; the Thirty Metre Telescope will help bring them closer.
