From UPSC perspective, the following things are important :
Prelims level: International Liquid Mirror Telescope (ILMT)
Mains level: Not Much
The four-meter International Liquid Mirror Telescope (ILMT) saw the first light recently, gazing out from its vantage on Devasthal, a hill in Uttarakhand.
What is the ILMT?
- The telescope has been built by a collaboration of scientists from Canada, Belgium and India.
- It is located at an altitude of 2,450 metres on the Devasthal Observatory campus of the Aryabhata Research Institute of Observational Sciences (ARIES) in Nainital district.
- A large pool of mercury placed in a vessel is spun around so fast that it curves into a parabolic shape. Since mercury is reflective, this shape helps in focusing the reflected light.
- Nearly 50 litres of mercury, weighing close to 700 kilograms, is spun hard to form a paraboloid mirror of just 4 mm thickness and a diameter of about 4 metres.
- A thin sheet of mylar protects the mercury from the wind.
- Once it starts making observations, the telescope will collect gigabytes of data, which will need to be analysed using artificial intelligence and machine learning (AI and ML) tools.
It’s utility
- The telescope will make sky surveys possible and obtain images that can help observe transient phenomena.
- It will help analyse events such as supernovae and record the presence of space debris or meteorites — basically, watch the skies.
What is the first image?
- The first image made by the telescope consisted of several stars and a galaxy, NGC 4274, which is 45 million light years away.
- The telescope, having a primary mirror that is liquid, cannot be turned and pointed in any direction.
- It “stares” at the zenith and watches the sky as the earth rotates, thereby giving a view of different objects.
- This property can be used to scan and survey the sky, and observe transients and moving objects such as meteorites.
- It will work in tandem with the existing 3.6-metre Devasthal Optical Telescope.

From UPSC perspective, the following things are important :
Prelims level: Overseas Indians
Mains level: Issues faced by Overseas Indians
A national helpline for women deserted in Non-Resident Indian (NRI) marriages and the need for a dedicated fund to provide assistance to them are among the recommendations made at a consultation organized by the National Commission for Women (NCW).
What are the issues faced by NRI wives?
- Abandon after marriage
- Inconclusive divorces filed abroad
- Child custody disputes
Classification of Overseas Indians
Overseas Indians, officially known as Non-resident Indians (NRIs) or Persons of Indian Origin (PIOs), are people of Indian birth, descent or origin who live outside the Republic of India:
(A) Non-Resident Indian (NRI)
- Strictly asserting non-resident refers only to the tax status of a person who, as per section 6 of the Income-tax Act of 1961, has not resided in India for a specified period for the purposes of the Act.
- The rates of income tax are different for persons who are “resident in India” and for NRIs.
(B) Person of Indian Origin (PIO)
Person of Indian Origin (PIO) means a foreign citizen (except a national of Pakistan, Afghanistan, Bangladesh, China, Iran, Bhutan, Sri Lanka and/or Nepal), who:
- at any time held an Indian passport OR
- either of their parents/grandparents/great-grandparents were born and permanently resident in India as defined in GoI Act, 1935 and other territories that became part of India thereafter provided neither was at any time a citizen of any of the aforesaid countries OR
- is a spouse of a citizen of India or a PIO.
(C) Overseas Citizenship of India (OCI)
- After multiple efforts by leaders across the Indian political spectrum, a pseudo-citizenship scheme was established, the “Overseas Citizenship of India”, commonly referred to as the OCI card.
- The Constitution of India does not permit full dual citizenship.
- The OCI card is effectively a long-term visa, with restrictions on voting rights and government jobs.

From UPSC perspective, the following things are important :
Prelims level: Liquid Nano Urea (LNU)
Mains level: India's fertilizer subsidy
During his visit to Gujarat, Prime Minister inaugurated the country’s first liquid nano urea plant at Kalol.
Liquid Nano Urea (LNU)
- Urea is chemical nitrogen fertiliser, white in colour, which artificially provides nitrogen, a major nutrient required by plants.
- LNU is essentially urea in the form of a nanoparticle.
- It is sprayed directly on the leaves and gets absorbed by the plant.
- Fertilisers in nano form provide a targeted supply of nutrients to crops, as they are absorbed by the stomata, pores found on the epidermis of leaves.
- According to IFFCO, liquid nano urea contains 4 per cent total nitrogen (w/v) evenly dispersed in water.
- The size of a nano nitrogen particle varies from 20-50 nm. (A nanometre is equal to a billionth of a metre.)
Significance of LNU
- This patented product is expected to not only substitute imported urea, but to also produce better results in farms.
- Apart from reducing the country’s subsidy bill, it is aimed at reducing the unbalanced and indiscriminate use of conventional urea.
- It will help increase crop productivity, and reduce soil, water, and air pollution.
Using LNU
- The liquid nano urea produced by Indian Farmers Fertiliser Cooperative (IFFCO) Limited comes in a half-litre bottle priced at Rs 240, and carries no burden of subsidy currently.
- By contrast, a farmer pays around Rs 300 for a 50-kg bag of heavily subsidised urea.
- According to IFFCO, a bottle of the nano urea can effectively replace at least one bag of urea.
How efficient is LNU?
- While conventional urea has an efficiency of about 25 per cent, the efficiency of liquid nano urea can be as high as 85-90 per cent.
- Conventional urea fails to have the desired impact on crops as it is often applied incorrectly, and the nitrogen in it is vaporized or lost as a gas.
- A lot of nitrogen is also washed away during irrigation.
- Liquid nano urea has a shelf life of a year, and farmers need not be worried about “caking” when it comes in contact with moisture.

From UPSC perspective, the following things are important :
Prelims level: Astra AAM
Mains level: India's missile arsenal
The Ministry of Defence has signed a contract with Bharat Dynamics Ltd (BDL) for the supply of the Astra Mark-1for deployment on fighter jets of the Indian Air Force and Indian Navy.
Astra Missile
- The Astra Mk-1 is a beyond visual range (BVR), air-to-air missile (AAM).
- The Astra project was officially launched in the early 2000s with defined parameters and proposed future variants.
- The missile has been designed and developed by the Defence Research and Development Organisation (DRDO).
- It will be deployed on fighter jets like Sukhoi-30 MKI and Tejas of the IAF and the Mig-29K of the Navy.
- BVM missiles are capable of engaging beyond the range of 20 nautical miles or 37 kilometres.
Range and its Variants
- While the range for Astra Mk-1 is around 110 km, the Mk-2 with a range over 150 km is under development and Mk-3 version with a longer range is being envisaged.
- One more version of Astra, with a range smaller than Mk-1 is also under development.
Strategic significance
- The missile has been designed based on requirements specified by the IAF for BVR as well as close-combat engagement, reducing the dependency on foreign sources.
- AAMs with BVR capability provides large stand-off ranges to own fighter aircraft.
- It can neutralise adversary airborne assets without exposing adversary air defence measures.
- Stand-off range means the missile is launched at a distance sufficient to allow the attacking side to evade defensive fire from the target.
- Astra is technologically and economically superior to many such imported missile
- The missile can travel at speeds more than four times that of sound and can reach a maximum altitude of 20 km, making it extremely flexible for air combat.

From UPSC perspective, the following things are important :
Prelims level: Railway links mentioned
Mains level: India-Bangladesh connectivity
Two years after they were stopped due to the onset of the pandemic, passenger train services between India and Bangladesh resumed with the Bandhan Express setting off from Kolkata for Khulna and the Maitree Express starting its run from Dhaka for Kolkata.
History of Rail Connectivity
- The Bandhan Express was resumed by rebooting a long-forgotten rail link between Kolkata and the industrial hub of Khulna, the third-largest city of Bangladesh.
- In 1965, this route was served by the Barisal Express, which was stopped due to the India-Pakistan war.
- The Modi government along with the Sheikh Hasina regime restarted that with Bandhan in 2017.
- The Bandhan Express was the second train to be flagged off after the introduction of Maitree Express between Kolkata and Dhaka Cantonment in April, 2008.
- It covers the distance between Kolkata and Khulna via Petrapole and Benapole border route to cater to the demands of the people from both the countries.
- The Bandhan Express was resumed in 2017 by rebooting a long-forgotten rail link between Kolkata and the industrial hub of Khulna.
Beyond passenger travel
- The governments of both the countries have been working towards strengthening the rail link between them, and not just through passenger trains.
- In August 2021, the two sides started regular movement of freight trains between the newly-restored link between Haldibari in India and Chilahati in Bangladesh.
- The Haldibari-Chilahati rail link between India and the then East Pakistan was also operational till 1965 and stopped due to the war.
- This was part of the broad gauge main route from Kolkata to Siliguri at the time of Partition.
- The two sides envisage at least 20 freight trains to cross the border per month on this link.
Rail infrastructure
- Once part of a single, seamless railway network under British rule, trains continued to pass between the two countries even after the Partition.
- The infrastructure to connect the two sides through railways was, therefore, largely present.
- Policymakers on both sides viewed this as an opportunity to deepen diplomatic ties using cross-border movements of goods and passengers.
- Five rail links have so far been rebooted between India and Bangladesh:
Petrapole (India)-Benapole (Bangladesh), Gede (India)- Darshana (Bangladesh), Singhabad (India)-Rohanpur (Bangladesh), Radhikapur (India)-Birol (Bangladesh) and the Haldibari-Chilahati link

From UPSC perspective, the following things are important :
Prelims level: Various terms related to Monsoon
Mains level: Indian Monsoon
The monsoon has reached Kerala, the India Meteorological Department (IMD).
What does the “Onset of Monsoon” mean?
- The onset of the monsoon over Kerala marks the beginning of the four-month — June-September — southwest monsoon season over India.
- It brings more than 70 per cent of the country’s annual rainfall. This marks a significant day in India’s economic calendar.
- IMD announces it only after certain newly defined and measurable parameters, adopted in 2016, are met.
- Broadly, the IMD checks for the consistency of rainfall over a defined geography, its intensity, and wind speed.
(1) Rainfall
- The IMD declares the onset of the monsoon if at least 60% of 14 designated meteorological stations in Kerala and Lakshadweep.
- The 14 enlisted stations are: Minicoy, Amini, Thiruvananthapuram, Punalur, Kollam, Alappuzha, Kottayam, Kochi, Thrissur, Kozhikode, Thalassery, Kannur, Kasaragod, and Mangaluru.
- It records at least 2.5 mm of rain for two consecutive days at any time after May 10.
- In such a situation, the onset over Kerala is declared on the second day, provided specific wind and temperature criteria are also fulfilled.
(2) Wind field
- The depth of westerlies should be up to 600 hectopascal (1 hPa is equal to 1 millibar of pressure) in the area bound by the equator to 10ºN latitude, and from longitude 55ºE to 80ºE.
- The zonal wind speed over the area bound by 5-10ºN latitude and 70-80ºE longitude should be of the order of 15-20 knots (28-37 kph) at 925 hPa.
(3) Heat
- According to IMD, the INSAT-derived Outgoing Longwave Radiation (OLR) value (a measure of the energy emitted to space by the Earth’s surface, oceans, and atmosphere) should be below 200 watt per sq m (wm2).
- This is measured in the box confined by 5-10ºN latitude and 70-75ºE latitude.
Is it unusual for the monsoon to hit the Kerala coast early?
- Neither early nor late onset of the monsoon is unusual.
- In 2018 and 2017, the onset over Kerala occurred on May 29 and May 30, respectively.
- In 2010, onset was realised on May 31.
- In 2020 and 2013, the monsoon was exactly on time, hitting the Kerala coast on June 1.
Does an early onset foretell a good monsoon?
- No, it does not — just as a delay does not foretell a poor monsoon.
- The onset is just an event that happens during the progress of the monsoon over the Indian subcontinent.
- A delay of a few days, or perhaps the monsoon arriving a few days early, has no bearing on the quality or amount of rainfall.
How does the monsoon spread across the country after hitting Kerala coast?
- The northward progression of the monsoon after it has hit the Kerala coast depends on a lot of local factors, including the creation of low pressure areas.
- Though this year monsoon has arrived early, it is possible that despite a late onset over Kerala, other parts of the country start getting rain on time.
- After its onset over Kerala, the monsoon spreads over the entire country by July 15.

From UPSC perspective, the following things are important :
Prelims level: West Nile Virus
Mains level: Vector borne diseases
The Kerala health department is on alert after the death occurred due to the West Nile Virus.
West Nile Virus
- The West Nile Virus is a mosquito-borne, single-stranded RNA virus.
- According to the WHO, it is a member of the flavivirus genus and belongs to the Japanese Encephalitis antigenic complex of the family Flaviviridae.
How does it spread?
- Culex species of mosquitoes act as the principal vectors for transmission.
- It is transmitted by infected mosquitoes between and among humans and animals, including birds, which are the reservoir host of the virus.
- Mosquitoes become infected when they feed on infected birds, which circulate the virus in their blood for a few days.
- The virus eventually gets into the mosquito’s salivary glands.
- During later blood meals (when mosquitoes bite), the virus may be injected into humans and animals, where it can multiply and possibly cause illness.
- WNV can also spread through blood transfusion, from an infected mother to her child, or through exposure to the virus in laboratories.
- It is not known to spread by contact with infected humans or animals.
Symptoms of WNV infection
- The disease is asymptomatic in 80% of the infected people.
- The rest develop what is called the West Nile fever or severe West Nile disease.
- In these 20% cases, the symptoms include fever, headache, fatigue, body aches, nausea, rash, and swollen glands.
- Severe infection can lead to encephalitis, meningitis, paralysis, and even death.
- It is estimated that approximately 1 in 150 persons infected with the West Nile Virus will develop a more severe form of the disease.
- Recovery from severe illness might take several weeks or months.
- It usually turns fatal in persons with co-morbidities and immuno-compromised persons (such as transplant patients).

From UPSC perspective, the following things are important :
Prelims level: Man Booker Price
Mains level: NA
Author Geetanjali Shree’s translated Hindi novel, Tomb of Sand, became the first Indian language book to win the International Booker Prize.
Note: Such topics hold very little relevance for CSE prelims. However, last year experience make such topics more uncertain. Still such topics hold relevance for other exams such as CAPF and state PSCs.
What is the Booker Prize?
- The Booker Prize is one of the best-known literary awards for fiction writing in English, including both novels and collections of short stories.
- It was first awarded in 1969.
- Every year a panel of judges decides the best work of the year, with the criteria being that it must be written in English and published in the UK and Ireland.
- This panel of judges is picked from among eminent cultural historians, writers, professors, and novelists, and others from related fields.
- For the Booker Prize, the winner receives £50,000.
About the book
- The 2018 novel titled ‘Ret Samadhi’ was translated by Daisy Rockwell and published as ‘Tomb of Sand’ in 2021.
- The prize is one of two literary awards given out annually by the Booker Prize Foundation, a charity whose stated aim is to “promote the art and value of literature for the public benefit”.
What about the International Booker Prize?
- The International Booker Prize began in 2005.
- A biennial prize initially, it was then awarded for a body of work available in English, including translations, with Alice Munro, Lydia Davis and Philip Roth becoming some of the early winners.
- In 2015, the rules of the International prize changed to make it an annual affair.
- The new rules stipulated that it will be awarded annually for a single book, written in another language and translated into English.
- The £50,000 prize money is divided equally between the author and translator each year.
Why is it called the ‘Booker’?
- The Booker Prize, from 1969 to 2001, was named simply after the Booker Group Limited – a British food wholesale operator that was its initial sponsor.
- The Man Group, an investment management firm based in the UK, began to sponsor the prize in 2002 and it thus came to be known as The Man Booker Prize.
- The Man Group ended their sponsorship in 2019.
- Crankstart, an American charitable foundation, has been the sponsor after that. The prize name has changed back to the ‘Booker’ since then.
Who have been some prominent winners?
- Prominent winners of the coveted prize include Margaret Atwood (‘The Testaments’), Yann Martel (‘Life of Pi’), and Julian Barnes (‘The Sense of an Ending’).
- Many Indian-origin writers have won the Booker in the past, such as Arundhati Roy (‘The God of Small Things’), Salman Rushdie (‘Midnight’s Children’), Kiran Desai (‘The Inheritance of Loss’), and Aravind Adiga (‘The White Tiger’).
- Shree is the first Indian to win an international prize.

From UPSC perspective, the following things are important :
Prelims level: Monkey Pox
Mains level: Rise in zoonotic diseases
With cases being reported from across the world, monkeypox has caught everyone’s attention.
What is Monkeypox?
- Monkeypox is not a new virus.
- The virus, belonging to the poxvirus family of viruses, was first identified in monkeys way back in 1958, and therefore the name.
- The first human case was described in 1970 from the Democratic Republic of Congo.
- Many sporadic outbreaks of animal to human as well as human to human transmission has occurred in Central and West Africa in the past with significant mortality.
- After the elimination of smallpox, monkeypox has become one of the dominant poxviruses in humans, with cases increasing over years along with a consequent reduction in the age-group affected.
How is it transmitted?
- Since the transmission occurs only with close contact, the outbreaks have been in many cases self-limiting.
- Since in the majority of affected people, the incubation period ranges from five to 21 days and is often mild or self-limiting, asymptomatic cases could transmit the disease unknowingly.
- The outbreaks in Central Africa are thought to have been contributed by close contact with animals in regions adjoining forests.
- While monkeys are possibly only incidental hosts, the reservoir is not known.
- It is believed that rodents and non-human primates could be potential reservoirs.
Does the virus mutate?
- Monkeypox virus is a DNA virus with a quite large genome of around 2,00,000 nucleotide bases.
- While being a DNA virus, the rate of mutations in the monkeypox virus is significantly lower (~1-2 mutations per year) compared to RNA viruses like SARS-CoV-2.
- The low rate of mutation therefore limits the wide application of genomic surveillance in providing detailed clues to the networks of transmission for monkeypox.
- A number of genome sequences in recent years from Africa and across the world suggest that there are two distinct clades of the virus — the Congo Basin/Central African clade and the West African clade.
- Each of the clades further have many lineages.
What do the genomes say?
- With over a dozen genome sequences of monkeypox, it is reassuring that the sequences are quite identical to each other suggesting that only a few introductions resulted in the present spread of cases.
- Additionally, almost all genomes have come from the West African clade, which has much lesser fatality compared to the Central African one.
- This also roughly corroborates with the epidemiological understanding that major congregations in the recent past contributed to the widespread transmission across different countries.
Does it have an effective vaccine?
- It is reassuring that we know quite a lot more about the virus and its transmission patterns.
- We also have effective ways of preventing the spread, including a vaccine.
- Smallpox/vaccinia vaccine provides protection.
- While the vaccine has been discontinued in 1980 following the eradication of smallpox, emergency stockpiles of the vaccines are maintained by many countries.
- Younger individuals are unlikely to have received the vaccine and are therefore potentially susceptible to monkeypox which could partly explain its emergence in younger individuals.

From UPSC perspective, the following things are important :
Prelims level: Service charges on food
Mains level: Not Much
The Centre has called a meeting of restaurant owners over service charge levied by them on customers.
Why in news?
- The restaurants are collecting service charges from consumers by default, even though collection of any such charge is voluntary and at the discretion of consumers and not mandatory as per law.
What are the components of a food bill?
- A restaurant bill in India comprises food charge (from the menu), with an addition of service charge (anywhere between 5 to 15 per cent) and a 5 per cent GST on this amount (IGST+SGST).
- This is for all kinds of standalone restaurants.
- In case a restaurant is located inside a hotel wherein room rate is upwards of Rs 7,500 (mostly in case of five-stars), the GST would be 18 per cent.
Nature of Service charge
- While the GST is a mandatory component as per law, the service charge is supposed to be optional.
- It is the equivalent of what is known as gratuity around the world, or tip, in casual parlance.
- Most restaurants decide the service charge on their own, and print it at the bottom of the menu with an asterisk.
Policy measures
- The Ministry of Consumer Affairs had come out with “Guidelines on Fair Trade Practices Related to Charging of Service Charge from Consumers by Hotels/ Restaurants”.
- Here it was clearly mentioned that a component of service is inherent in the provision of food and beverages ordered by a customer.
- Hence the pricing of the product is expected to cover both the goods and service components.
- It said that the bill “may clearly display that service charge is voluntary, and the service charge column of the bill may be left blank for the customer to fill up before making payment.”
What do the restaurants say?
- The levy of service charge by a restaurant is a matter of individual policy to decide if it is to be charged or not.
- There is no illegality in levying such a charge.
- Once the customer is made aware of such a charge in advance and then decides to place the order, it becomes an agreement between the parties, and is not an unfair trade practice.
- GST is also paid on the said charge to the Government.
Where does the fund go?
- Restaurants claim that a major chunk of the service charge thus collected goes to the staff, while the rest goes towards a welfare fund to help them out during good and bad times.
- It’s a default billing option, even as customers can choose not to pay it if they don’t want to.
- Of course, they are paid the salaries but the service charge works as an incentive for them.
- Restaurateurs also say that patrons can decide not to pay the charge and tip the server directly, but in this case, the backroom staff doesn’t get anything.
- A service charge ensures all staff members are rewarded evenly.
What is the issue then?
- The issue is that almost all restaurants have put service charge (fixed at their own accord) as a default billing option.
- And if a consumer is aware that it is not compulsory and wants it removed or wants to tip the server directly, the onus is on them to convince the management why they don’t want to pay it.
- The department says they received several complaints saying it leads to public embarrassment and spoils the dining experience since at the end of it, they either pay the charge quietly and exit the place feeling cheated, or have to try hard to get it removed.
- Also, there is no transparency as to where this charge goes.
- The officials also say that collecting service charge on their own and paying GST on it to the government doesn’t make it authorised.
Problems faced by customers
- It is this component which has come under dispute from time to time, with consumers arguing they are not bound to pay it.
- It also said that hotels and restaurants charging tips from customers without their express consent in the name of service charges amounts to unfair trade practice.

Prelims level: Qutub Minar
Mains level: Not Much
The Qutub Minar complex is not a place of worship and its character cannot be changed now, the Archaeological Survey of India submitted in a Delhi Court while opposing a plea challenging the dismissal of a civil suit seeking “restoration” of temples on the premises.
What is the case?
- The original suit claimed that 27 temples were demolished to build the Quwwat-ul-Islam mosque at the Qutub Minar complex.
- This pleas was dismissed last year under the provisions of Places of Worship (Special Provisions) Act, 1991.
- The Additional District Judge (ADJ) has now reserved the order.
- The petitioner said that the dismissal of the original suit based on the 1991 Act was wrong.
- The Qutub Minar complex comes under the purview of the Ancient Monuments and Archaeological Sites and Remains (AMASR) Act of 1958.
Why in news now?
- The ASI now submitted that the Qutub Minar complex was not a place of worship when it was first notified as a protected monument in 1914.
- The ASI, explained that the character of a monument is decided on the date when it comes under protection.
About Qutub Minar
- The Qutub Minar is a minaret and “victory tower” that forms part of the Qutb complex, which lies at the site of Delhi’s oldest fortified city, Lal Kot, founded by the Tomar Rajputs.
- It is a UNESCO World Heritage Site in the Mehrauli area of South Delhi.
- It can be compared to the 62-metre all-brick Minaret of Jam in Afghanistan, of c. 1190, which was constructed a decade or so before the probable start of the Delhi tower.
- The surfaces of both are elaborately decorated with inscriptions and geometric patterns.
- The Qutb Minar has a shaft that is fluted with “superb stalactite bracketing under the balconies” at the top of each stage.
Its construction
- The Qutb Minar was built over the ruins of the Lal Kot, the citadel of Dhillika.
- Qutub Minar was begun after the Quwwat-ul-Islam Mosque, which was started around 1192 by Qutb-ud-din Aibak, first ruler of the Delhi Sultanate.
- It is usually thought that the tower is named for Qutb-ud-din Aibak, who began it.
- It is also possible that it is named after Khwaja Qutbuddin Bakhtiar Kaki a 13th-century sufi saint, because Shamsuddin Iltutmish was a devotee of his.
- Quwwat-ul-Islam Mosque, to the north-east of the Minar was built by Qutub-ud-Din Aibak in A.D. 1198.
- It consists of a rectangular courtyard enclosed by cloisters, erected with the carved columns and architectural members of 27 Jain and Hindu temples, which were demolished by Qutub-ud-Din.
- This is recorded in his inscription on the main eastern entrance.

Prelims level: Prithviraj Chauhan
Mains level: NA
There is controversy around a new film where some communities of Rajasthan are laying claim over the 12th century emperor Prithviraj Chauhan.
Prithviraj Chauhan
- Prithviraj Chauhan (1177–1192 CE) popularly known as a king from the Chauhan (Chahamana) dynasty who ruled the territory of Sapadalaksha, with his capital at Ajmer in present-day Rajasthan.
- Ascending the throne as a minor in 1177 CE, Prithviraj inherited a kingdom which stretched from Thanesar in the north to Jahazpur (Mewar) in the south.
His legend
- He aimed to expand by military actions against neighbouring kingdoms, most notably defeating the Chandela’s.
- Prithviraj unified several Rajput clans and defeated the Ghurid army led by Muhammad Ghori near Taraori in 1191 AD.
- However, in 1192 CE, Ghori returned with an army of Turkish mounted archers and defeated the Rajput army on the same battlefield.
- Prithviraj fled the battlefield, but was captured near Sirsa and executed.
- His defeat at Tarain is seen as a landmark event in the Islamic conquest of India, and has been described in several semi-legendary accounts, most notably the Prithviraj Raso.
Prithviraj in literary works
- The image of Prithviraj as a fearless and skilled warrior that is now etched in the folk imagination can be traced back to his depiction in ‘Prithviraj Raso’.
- This was a poem in Brajbhasha attributed to Chand Bardai, which is thought to have been composed in the 16th century.
- James Mill’s ‘The History of British India’ (1817) categorized Indian history into the Hindu, Muhammadan and British periods.
- In this formulation, Prithviraj Chauhan would be the last ruler of ‘Hindu’ India.
Why is he being revived?
- To a vocal section of the Hindu right, Prithviraj Chauhan appears as “the last Hindu emperor” of India who made a valiant attempt to stop the radical invaders.
- In the popular imagination, he is the heroic figure who symbolises the exalted ideals of patriotism and national pride.
- However the historical evidence demonstrates rather different ways in which Prithviraj has been seen over the ages.

From UPSC perspective, the following things are important :
Prelims level: Storage gain in wheat
Mains level: NA
Punjab’s state procurement agencies (SPAs) are seeking a waiver of ‘storage gain’.
What is ‘storage gain’ in wheat?
- Wheat, considered a ‘living grain’, tends to gain some weight during storage.
- This is known as ‘storage gain’ and it mostly happens due to absorption of moisture.
- There are three parts of the grain — bran (outer layer rich in fibre), germ (inner layer rich in nutrients) and endosperm (bulk of the kernel which contains minerals and vitamins).
- The moisture is mostly absorbed by the endosperm.
Who compensates whom for ‘storage gain’?
- State procurement agencies, which purchase and store wheat at their facilities, are required to give one kg wheat extra per quintal to the Food Corporation of India (FCI).
- While 20% of wheat, procured by the FCI and the SPAs, is moved immediately after procurement.
- It is usually on the remaining 80%, which is moved out after July 1 every year that storage gain has to be accounted for due to longer storage duration.

From UPSC perspective, the following things are important :
Prelims level: Project Wardec
Mains level: Not Much
The Army Training Command signed a memorandum of understanding (MoU) with Gandhinagar-based Rashtriya Raksha University (RRU) to develop a ‘Wargame Research and Development Centre (WARDEC)’ in New Delhi.
What is Project WARDEC?
- The project ‘WARDEC’ will be a first-of-its-kind simulation-based training centre in India that will use artificial intelligence (AI) to design virtual reality war-games.
- The Wargame Research and Development Centre will be used by the Army to train its soldiers and test their strategies through “metaverse-enabled gameplay”.
- The wargame models will be designed to prepare for wars as well as counter-terror and counter-insurgency operations.
Where will the centre come up and when?
- The centre will come up in a military zone in New Delhi, confirmed RRU officials privy to the development.
- The RRU will join hands with Tech Mahindra to develop the centre in the coming three to four months.
- The RRU, an institute under the Ministry of Home Affairs (MHA), specialises in national security and policing.
- Located in Gandhinagar’s Lavad village, it is an “institute of national importance” – a status granted to it by an Act of Parliament.
How will these simulation exercises play out?
- Soldiers will test their skills in the metaverse where their surroundings will be simulated using a combination of virtual reality (VR) and augmented reality (AR).
- In metaverse, the players will get a realistic experience of the actual situation.
- If a weapon weighing 5 kg drops or the air pressure falls, they will feel it like anyone would in a live situation, real-time.
- The game would play out player versus player, player versus computer or even computer versus computer.
How will the centre help the Army?
- The Army intends to use the war-game centre to train its officers in military strategies.
- Indian Army will provide data to set the backdrop of the gameplay, so that participants get a realistic experience.
- In Army, it is often said that the enemy can ambush you from 361 directions, where 360 sides are around the soldier, and one is above in case there is an airdrop.
- So, wargame simulation helps the Army think of all possible scenarios.
What promise does AI-based wargame simulation hold?
- Apart from the armed forces, the BSF, CRPF, CISF, ITBP and SSB can also use the metaverse-enabled simulation exercises for better training.
- The use of AI can provide a totally immersive training experience as it can simulate a battlefield close to reality and map several eventualities in the probable event of a war.
How many countries use such wargaming drills?
- Since the 9/11 attacks, use of information technology-enabled wargaming is preferred by several countries like the US, Israel, the UK to prepare for possibilities in case of terror attacks or war.
- In March 2014, several world leaders, including former German chancellor Angela Merkel, former US president Barack Obama and Chinese president Xi Jinping had played a war simulation game.
- It was during the Hague Summit about how to react in case of a nuclear attack.
- In that case, the target of the nuclear attack was a fictional country named Brinia.

From UPSC perspective, the following things are important :
Prelims level: Sudden Infant Death Syndrome (SIDS)
Mains level: Not Much
A team of scientists from Australia have found that babies at risk of the mysterious Sudden Infant Death Syndrome, or SIDS, generally have low levels of an enzyme called butyrylcholinesterase (BChE) in their blood.
What is SIDS?
- Sudden Infant Death Syndrome refers to the sudden and unexpected death of an otherwise healthy infant under the age of one, generally while they are sleeping.
- Most SIDS-related deaths occur in infants between the age of 1-4 months.
- According to the NHS website, parents can reduce the risk of SIDS by not smoking while pregnant or after the baby is born and ensuring that the baby is placed on their back when they sleep.
- Some health experts have said that it is associated with issues in the part of an infant’s brain that controls breathing and waking up.
Prevalence of SIDS
- SIDS, also known as ‘cot death’, has claimed the lives of thousands of children across the West.
- US estimates that about 3,400 babies die suddenly and unexpectedly every year.
- Meanwhile, the United Kingdom reports about 200 such deaths annually.
What does the new study say?
- The study assessed whether there was something inherently different in babies that succumbed to SIDS.
- The researchers compared dried blood samples from 655 healthy babies, 26 babies who died due to SIDS and 41 babies who died of other causes.
- The team found that around nine of ten babies who died from SIDS had lower levels of BChE enzymes than the babies in the other two groups.
What is the BChE (Butyrylcholinesterase) enzyme responsible for?
- These enzymes are responsible for sending out signals that make a baby wake up, turn her head, or gasp for breath.
- It is part of the autonomic system, and controls function like blood pressure and breathing.

From UPSC perspective, the following things are important :
Prelims level: Places associated with Buddha
Mains level: Buddhist architecture
Prime Minister in Lumbini, on the occasion of Buddha Purnima, said that his birthplace Vadnagar in Gujarat’s Mehsana district had been a great centre for Buddhist learning centuries ago.
Vadnagar’s ties with Buddhism
- In 2014, the excavation work has brought up Buddhist relics and around 20,000 artefacts, some dating back to the 2nd century.
- Among these are an elliptical structure and a circular stupa along with a square memorial stupa of 2×2 metres and 130 centimetres in height with a wall enclosure.
- It is like a platform which has a chamber in the centre that resembles a pradakshina path.
- Further, bowls said to be used by monks have been found during the excavations, which have a terracotta sealing with inscriptions of namassarvagyaya and a face-shaped pendant with tritatva symbol.
- Sacred relics of the Buddha were even found in Devni Mori in Aravalli district of Gujarat.
In travellers record
- Vadnagar is mentioned often in the Puranas and even in the travelogue of the great Chinese traveler, Hiuen Tsang (7th century), as a rich and flourishing town.
- He is believed to have visited the state in 641 AD.
- It adds how some of the names attributed to Vadnagar in history are Chamatkarpur, Anandpur, Snehpur and Vimalpur.
- It also had snippets about other Buddhist heritage sites in Gujarat, such as Junagadh, Kutch and Bharuch.
Back2Basics: Places associated with Buddha
These are three of the few holiest sites in Buddhism:
- Bodh Gaya in Bihar, the site of the enlightenment of Gautama Buddha under a tree and top site in the list of world heritage sites in India.
- Kesaria stupa is a Buddhist stupa in Kesariya, located at a distance of 110 kilometres (68 mi) from Patna, in the Champaran (east) district of Bihar, India. The first construction of the Stupa is dated to the 3rd century BCE. Kesariya Stupa has a circumference of almost 400 feet (120 m) and raises to a height of about 104 feet (32 m).
- Nalanda was a renowned Buddhist University in the ancient kingdom of Magadha (modern-day Bihar) in India.Buddhist texts describe it as a Mahavihara, a revered Buddhist monastery.
- Sarnath near Varanasi in Uttar Pradesh, the site of the first sermon (Dhammacakkappavattana Sutta), where Buddha taught about the Middle Way, the Four Noble Truths and Noble Eightfold Path.
- Kushinagar in Uttar Pradesh, the site of the Buddha’s parinirvana and home of many famous meditation & prayer offering sites in India.

From UPSC perspective, the following things are important :
Prelims level: Repo Rate
Mains level: Inflation targetting by MPC
Earlier this month, the RBI, in a surprise move decided unanimously to raise the “policy repo rate by 40 basis points to 4.40%, with immediate effect”.
What is the Repo Rate?
- The repo rate is one of several direct and indirect instruments that are used by the RBI for implementing monetary policy.
- Specifically, the RBI defines the repo rate as the fixed interest rate at which it provides overnight liquidity to banks against the collateral of government and other approved securities under the liquidity adjustment facility (LAF).
- In other words, when banks have short-term requirements for funds, they can place government securities that they hold with the central bank and borrow money against these securities at the repo rate.
- Since this is the rate of interest that the RBI charges commercial banks such as SBI and ICICI Bank when it lends them money, it serves as a key benchmark for the lenders to in turn price the loans they offer to their borrowers.
Why is the repo rate such a crucial monetary tool?
- According to Investopedia, when government central banks repurchase securities from commercial lenders, they do so at a discounted rate that is known as the repo rate.
- The repo rate system allows central banks to control the money supply within economies by increasing or decreasing the availability of funds.
How does the repo rate work?
- Besides the direct loan pricing relationship, the repo rate also functions as a monetary tool by helping to regulate the availability of liquidity or funds in the banking system.
- For instance, when the repo rate is decreased, banks may find an incentive to sell securities back to the government in return for cash.
- This increases the money supply available to the general economy.
- Conversely, when the repo rate is increased, lenders would end up thinking twice before borrowing from the central bank at the repo window thus, reducing the availability of money supply in the economy.
- Since inflation is caused by more money chasing the same quantity of goods and services available in an economy, central banks tend to target regulation of money supply as a means to slow inflation.
What impact can a repo rate change have on inflation?
- Inflation can broadly be: mainly demand driven price gains, or a result of supply side factors.
- This in turn push up the costs of inputs used by producers of goods and providers of services.
- It is thus spurring inflation, or most often caused by a combination of both demand and supply side pressures.
- Changes to the repo rate to influence interest rates and the availability of money supply primarily work only on the demand side.
- It makes credit more expensive and savings more attractive and therefore dissuading consumption.
- However, they do little to address the supply side factors, be it the high price of commodities such as crude oil or metals or imported food items such as edible oils.

From UPSC perspective, the following things are important :
Prelims level: mRNA, RNA granules
Mains level: Not Much
Researchers at IISc Bangalore have identified a protein in yeast cells that dissolves RNA-protein complexes, also known as RNA granules.
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 are RNA granules?
- Inside the cytoplasm of any cell there are structures made of messenger RNA (mRNA) and proteins known as RNA granules.
- Unlike other structures in the cell (such as mitochondria), the RNA granules are not covered and confined by a membrane.
- This makes them highly dynamic in nature, thereby allowing them to constantly exchange components with the surrounding.
- RNA granules are present in the cytoplasm at low numbers under normal conditions but increase in number and size under stressful conditions including diseases.
Why are they unique?
- A defining feature which does not change from one organism to another (conserved) of the RNA granule protein components is the presence of stretches containing repeats of certain amino acids.
- Such stretches are referred to as low complexity regions.
- Repeats of arginine (R), glycine (G) and glycine (G) — known as RGG — are an example of low complexity sequence.
Functions of RNA granules
- Messenger RNAs are converted to proteins (building blocks of the cell) by the process of translation.
- RNA granules determine messenger RNA (mRNA) fate by deciding when and how much protein would be produced from mRNA.
- Protein synthesis is a multi-step and energy-expensive process.
- Therefore, a common strategy used by cells when it encounters unfavorable conditions is to shut down protein production and conserve energy to deal with a stressful situation.
- RNA granules help in the process of shutting down protein production.
- Some RNA granule types (such as Processing bodies or P-bodies) not only regulate protein production but also accomplish degradation and elimination of the mRNAs, which in turn helps in reducing protein production.
What is the recent study?
- Researchers concluded that low complexity sequences which normally promote granule formation, in this case promote the disintegration of RNA granules in yeast cells.
- They observed that the identified protein Sbp1 is specific for dissolving P-bodies and not stress granules which are related RNA granule type also present in the cytoplasm.
Significance of the study
- This study has highlighted the potential of amino acid repeats (RGG) as a therapeutic intervention.
- The study may help analyze the effect of repeat sequences in genetically engineered mice that accumulate insoluble pathological aggregates in brain cells.
- This could possibly help in treating neurodegenerative disorders such as Alzheimer’s disease.
