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?
- It is used in developing gene silencing therapies.
- It can be used in developing therapies for the treatment of cancer.
- It can be used to develop hormone replacement therapies.
- 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.

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.

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.

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.

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.

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.

Prelims level: GRACE FO mission
Mains level: Impact of climate changes on Cryosphere
The GRACE-FO mission has mapped deviation in Earth’s surface mass and spatial variations in the rate of sea-level rise between 1993 and 2018 using altimetric and gravimetric analysis.
Try this MCQ:
Q.NASA’s VIPER mission sometimes seen in news is related to the study of-
a)Moon
b)Venus
c)Sun
d)None of these
GRACE-FO Mission
- The Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) mission launched in 2018 is a partnership between NASA and the German Research Centre for Geosciences (GFZ).
- It is a successor to the original GRACE mission, which orbited Earth from 2002-2017.
- It carries on the extremely successful work of its predecessor while testing a new technology designed to dramatically improve the already remarkable precision of its measurement system.
How did NASA measure this?
(1) Altimetric Study
- Altimetry missions are used to know the ocean surface topography — the shape and height of the ocean’s peaks and valleys.
- Radar altimeters continually send out pulses of radio waves (microwaves) that bounce off the surface of the ocean and reflect back toward the satellite.
- The instrument calculates the time it takes for the signal to return, while also tracking the precise location of the satellite in space. From this, scientists can derive the height of the sea surface directly underneath the satellite.
(2) Gravimetric Study
- Gravimetry is a process of using ice’s gravitational pull on a pair of satellites. It helps estimate ice loss and its contribution to sea-level rise.
- The twin satellites in each mission detect subtle shifts in Earth’s gravity field.
- The strength of gravitational forces is determined by mass, so changes in Earth’s gravity field indicate a change or redistribution in mass.

From UPSC perspective, the following things are important :
Prelims level: Other Service Providers (OSP)
Mains level: Various sectors of the economy
The Department of Telecom (DoT) has eased the rules for registration, submission of bank guarantee and other norms for other service providers (OSP) in the business process outsourcing (BPO) and information technology-enabled services (ITes).
Recall your basics from NCERT books… Sectors of the Economy … More precisely, the Tertiary, Quaternary and Quinary Sectors.
What are Other Service Providers (OSP)?
- OSPs or other service providers are companies or firms which provide secondary or tertiary services such as telemarketing, telebanking or telemedicine for various companies, banks or hospital chains, respectively.
- As computers made their foray into the Indian information technology space, a number of such OSPs, which were either voice or non-voice based, came into the market.
- The sector required minimal investment but gave great returns in business, which prompted a large number of individuals and companies to float other service providing firms.
Registration of OSPs
- The new telecom policy of 1999 suggested that all OSPs register themselves so that the government could keep a check on the usage of its resources.
- Since most of these firms used leased telephone lines, this in turn used the telecom spectrum auctioned by the DoT, hence facing the regulation.
- Further, the registration was also made mandatory to ensure that firms did not establish fake OSPs which swindled customers under the garb of providing telebanking and other such sensitive services.
What were the various registration norms for OSPs?
- To start services in India, OSPs had to register themselves with the DoT and declare to the government as to how many employees were working in the firm as well as the area of service it was engaged in.
- For example, if a firm wished to provide telebanking services, it had to tell the government the number of people working with the BPO and the state that firms catered to.
- Further, the OSPs also have to declare whether they were providing services to domestic firms or international firms, and the nature of services being offered.
Significance of the new guidelines
- The guidelines will make it easier for BPOs and ITes firms in many ways, such as cutting down on the cost of location, rent for premises and other ancillary costs such as electricity and internet bills.
- The doing away of registration norms will also mean that there will be no renewal of such licenses and therefore will invite foreign companies to set up or expand their other service providing units in India.
- This change, in line with the norms of countries in the West can also allow employees to opt for freelancing for more than one company while working from home, thereby attracting more workers in the sector.

Prelims level: Einstein’s Eclipse
Mains level: General Relativity
This newscard is an excerpt from the original article published in the DownToEarth.
Einstein’s Eclipse
- Albert Einstein’s prediction of the bending of light by the gravity of the Sun, one of the components of his general theory of relativity, can be tested during a solar eclipse.
- Following an unsuccessful attempt to validate this prediction during the Solar eclipse of June 8, 1918, two expeditions were made to measure positions of stars during this eclipse.
- The eclipse presented a rare chance to verify one of the essential consequences of general relativity, the bending of light by gravity.
- Einstein’s theory predicted that rays of light passing near a massive body in space would be visibly bent as they followed the curve in space-time created by the body’s mass.
- In the case of a ray of light originating from a distant star and passing near the edge of the Sun, Einstein calculated a deflection of about 1.75 arc seconds.
Try this PYQ:
Q.Consider the following phenomena:
- Light is affected by gravity.
- The Universe is constantly expanding.
- Matter warps its surrounding space-time.
Which of the above is/are the predictions of Albert Einstein’s General Theory of Relativity, often discussed in media?
(a) 1 and 2 only
(b) 3 only
(c) 1 and 3 only
(d) 1, 2 and 3
What was studied during the eclipse?
- Einstein published his theory and predictions in 1915, and in 1919 the British physicist Sir Arthur Eddington took advantage of a total solar eclipse to attempt to detect the shifting images of stars near the limb of the sun.
- The problem was that during totality the sky does not get perfectly dark, and only a handful of stars were visible near the sun from which to make the measurement.
- The darkness of an eclipse, though, would allow the astronomers to observe and photograph the field of stars around the Sun.
- By comparing the photographs with reference images taken at night, it would be possible to measure how much the presence of the Sun had bent the stars’ light.
- Conveniently, a cluster of bright stars known as the Hyades would appear near the Sun during the eclipse.
Significance
- After several months of analysis, researchers announced in November that their findings supported the theory of general relativity.
- Media coverage tended to dwell on the recondite nature of Einstein’s work, emphasizing that there were only a handful of people in the world who could understand it.
- It could be argued that 1919 was the year when Einstein’s name became a byword for superhuman intellectual ability—making possible the small industry of Einstein-themed merchandise that still exists today.
Back2Basics: General Relativity
- Einstein’s theory proposes that gravity is not an actual force, but is instead a geometric distortion of space-time not predicted by ordinary Newtonian physics.
- The more mass you have to produce the gravity in a body, the more distortion you get.
- This distortion changes the trajectories of objects moving through space, and even the paths of light rays, as they pass close-by the massive body.
- Even so, this effect is very feeble for an object as massive as our own sun, so it takes enormous care to even detect that it is occurring.
- General Relativity predicts how much of this bending of light you should see given the mass of the object.
- Called ‘gravitational lensing’ it has been detected on the cosmological scale as entire clusters of galaxies distort the light from more distant galaxies behind them as this image from the Hubble Space Telescope shows.

Delhi CM has said that the “Pusa bio-decomposer” is a success in Delhi and he will inform the Supreme Court that it is an effective way to prevent stubble burning.
Pusa Bio-decomposer provides a unique alternative against the stubble burning practices.
Pusa Bio-decomposer
- It is a solution developed by the scientists at the Indian Agricultural Research Institute, Pusa, which can turn crop residue into manure in 15 to 20 days and therefore, can prevent stubble burning.
- It involves making a liquid formulation using Pusa decomposer capsules and readily available inputs, fermenting it over 8-10 days, and then spraying the mixture on fields.
- It is a mix of seven fungi that produce enzymes to digest cellulose, lignin and pectin in paddy straw.
- The fungi thrive at 30-32 degree Celsius, which is the temperature prevailing when paddy is harvested and wheat is sown.
Back2Basics: Decomposition
- Decomposition refers to a biological process of breaking down organic material into smaller constituent parts.
- The decomposition of organic substances is ecologically significant. It plays a part in the nutrient cycle. It is an essential process of recycling matter in the biosphere.
- A decomposer is an organism whose ecological function involves the recycling of nutrients by performing the natural process of decomposition as it feeds on decaying organisms.
- Examples of decomposers are fungi and bacteria that obtain their nutrients from a dead plant or animal material.
- They break down cells of dead plants and animals into simpler substances, which become organic nutrients available to the ecosystem.

A proposed museum reflecting the “culture and heritage of the people living in char-chaporis” has stirred up a controversy in Assam.
Do you know?
Phumdis are a series of floating islands, exclusive to the Loktak Lake in Manipur. They cover a substantial part of the lake area and are heterogeneous masses of vegetation, soil and organic matter, in different stages of decay.
What are char-chaporis?
- A char is a floating island while chaporis are low-lying flood-prone riverbanks.
- They are used interchangeably as they keep changing shapes — a char can become a chapori, or vice versa, depending on the push and pull of the Brahmaputra.
- Prone to floods and erosion, these areas are marked by low development indices.
- While Bengali-origin Muslims primarily occupy these islands, other communities such as Misings, Deoris, Kocharis, Nepalis also live here.
- In the popular imagination, however, chars have become synonymous to the Bengali-speaking Muslims of dubious nationality.
Who are the Miyas?
- The ‘Miya’ community comprises descendants of Muslim migrants from East Bengal (now Bangladesh) to Assam.
- They came to be referred to as ‘Miyas’, often in a derogatory manner.
- The community migrated in several waves — starting with the British annexation of Assam in 1826, and continuing into Partition and the 1971 Bangladesh Liberation War.

What is the correct chronological sequence of the above events?
(a) 1-2-3
(b) 2-1-3
(c) 3-2-1

Irish mutiny in India
- The Connaught Rangers were raised during the British Army reforms of 1881.
- A British Army battalion belonging to the Connaught Rangers was the one in which Irish soldiers mutinied in Jalandhar and Solan in Punjab.
- Solan now lies in Himachal Pradesh but in 1920 it was part of Punjab. The Ist Battalion of the Connaught Rangers was stationed in Jalandhar since January 1920 after it had taken part in the First World War.
Why did the mutiny take place?
- The troops were protesting against the behaviour of the ‘Black and Tans’ during the Irish War of Independence (1919-22).
- The Black and Tan were members of the Irish constabulary which had been recruited from Great Britain and mostly comprised demobilized soldiers who had fought in the First World War.
- The Irish soldiers felt that they must rise in solidarity with their compatriots back in Ireland and hence in June and July 1920 some of the regiment’s men mutinied.
- Some of the mutinied soldiers were later put through a court-martial.
Who were the Black and Tans?
- They were constables recruited into the Royal Irish Constabulary (RIC) as reinforcements during the Irish War of Independence.
- Recruitment began in Great Britain in January 1920 and about 10,000 men enlisted during the conflict.
- The vast majority were unemployed former soldiers from Great Britain who fought in the First World War, although some were from Ireland.

- The first was held off Okinawa island of Japan in the Western Pacific — the first time the exercise was held away from Indian shores — and the second in September 2007.
- The following year, Australia stopped participating. Japan became a regular participant only in 2015, making it a trilateral annual exercise since then.
Why is Australia’s participation important?
- The 2+2 dialogue ended with an agreement to uphold the rules-based international order, respect for the rule of law and freedom of navigation in the international seas and upholding the territorial integrity and sovereignty of all states.
- As the standoff in eastern Ladakh continues, the participation of four large navies from the Indo-Pacific region will send a message to China.
- It was the possibility of riling up China that had prevented India from expanding the Malabar Exercise, and from Australia joining it.
Quad is an exception
- Over the last few months, the Indian Navy has conducted a number of Passage Exercises (PASSEX) with navies from Japan, Australia and the US.
- But those were basic exercises to increase operability between the navies, while Malabar involves simulated war games.

From UPSC perspective, the following things are important :
Prelims level: D614G mutation
Mains level: Not Much
While novel coronavirus is undergoing many mutations, one particular mutation called D614G, according to a study, has become the dominant variant in the global COVID-19 pandemic.
Try this PYQ:
Q.Which one of the following statements is not correct?
(a) Hepatitis B virus is transmitted much like HIV.
(b) Hepatitis B, unlike Hepatitis C, does not have a vaccine.
(c) Globally, the number of people infected with Hepatitis B and C viruses is several times more than those infected with HIV.
(d) Some of those infected with Hepatitis B and C viruses do not show the symptoms for many years.
D614G mutation
- When the virus enters an individual’s body, it aims at creating copies of itself. When it makes an error in this copying process, we get a mutation.
- In this case, the virus replaced the aspartic acid (D) in the 614th position of the amino acid with glycine (G). Hence the mutation is called the D614G.
- This mutated form of the virus was first identified in China and then in Europe. Later it spread to other countries like the U.S. and Canada and was eventually reported in India.
Threats posed
- This particular mutation aids the virus in attaching more efficiently with the ACE2 receptor in the human host, thereby making it more successful in entering a human body than its predecessors.
- D614G show increased infectivity but it also displayed greater ability at attaching itself to the cell walls inside an individual’s nose and throat, increasing the viral load.
How prevalent is it in India?
- A study (reveals that the D614G was one of the most prevalent spike mutations even during the initial phase of the pandemic.
- Since then, D614G mutation’s ‘relative abundance’ has increased over time to 70% and above, in most states except Delhi.

16 Psyche
- Located around 370 million km away from Earth, asteroid 16 Psyche is one of the most massive objects in the asteroid belt in our solar system.
- The somewhat potato-shaped asteroid has a diameter of around 140 miles.
- It was first discovered on March 17, 1853, by the Italian astronomer Annibale de Gasparis and was named after the ancient Greek goddess of the soul, Psyche.
- Unlike most asteroids that are made up of rocks or ice, scientists believe that Psyche is a dense and largely metallic object thought to be the core of an earlier planet that failed in formation.
