    What is ‘Storage Gain’ in Wheat?

    Note4Students

    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.

    Project WARDEC: India’s upcoming AI-powered Wargame Centre

    Note4Students

    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.

    What is Sudden Infant Death Syndrome (SIDS)?

    Note4Students

    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.

    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

  • Monetary Policy Committee Notifications

    Explained: Repo Rate in India

    Note4Students

    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.

    RNA granules to treat neurodegenerative disorders

    Note4Students

    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.

    Iron in Tamil Nadu 4,200 years ago: A new dating and its significance

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Iron Age

    Mains level: Ancient Indian Civilizations

    Carbon dating of excavated finds in Tamil Nadu pushes evidence of iron being used in India back to 4,200 years ago, the Tamil Nadu government announced this week on the basis of an archaeological report.

    What is the news?

    • Before this, the earliest evidence of iron use was from 1900-2000 BCE for the country, and from 1500 BCE for Tamil Nadu.
    • The latest evidence dates the findings from Tamil Nadu to 2172 BCE! Much older.
    • The results of dating, used accelerator mass spectroscopy.

    Where were these objects found?

    • The excavations are from Mayiladumparai near Krishnagiri in Tamil Nadu, about 100 km south of Bengaluru.
    • Mayiladumparai is an important site with cultural material dating back between the Microlithic (30,000 BCE) and Early Historic (600 BCE) ages.
    • The site is situated in the midst of several archaeological sites such as Togarapalli, Gangavaram, Sandur, Vedarthattakkal, Guttur, Gidlur, Sappamutlu and Kappalavadi.

    Outcome: Varying span of Iron Age

    • The dates when humans entered the Iron Age vary from one region of the world to another.
    • In India, too, the date has been revised with successive findings over the decades.

    When the Iron Age is considered in India?

    • In 1979, use of iron was traced to 1300 BCE at Ahar in Rajasthan. This is what we have been reading in NCERTs.
    • Later, samples at Bukkasagara in Karnataka, indicating iron production, were dated back to 1530 BCE.
    • The date was subsequently pushed back to 1700-1800 BCE with excavations finding evidence of iron smelting at Raipura in the Mid-Ganga valley.
    • It was then to 1900-2000 BCE based on investigations in sites at Malhar near Varanasi and Brahmagiri in North Karnataka.
    • A series of dating results on finds from various parts in India have shown evidence of iron-ore technology before 1800 BCE.
    • Before the latest discovery, the earliest evidence of iron use for Tamil Nadu was from Thelunganur and Mangadu near Mettur, dating back to 1500 BCE.

    Historical significance

    • Iron is not known to have been used in the Indus Valley, from where the use of copper in India is said to have originated (1500 BCE).
    • But non-availability of copper for technological and mass exploitation forced other regions to remain in the Stone Age.
    • When iron technology was invented, it led to the production of agricultural tools and weapons, leading to production required for a civilisation ahead of economic and cultural progress.
    • While useful tools were made out of copper, these were brittle and not as strong as iron tools would be.
    • With the latest evidence tracing our Iron Age to 2000 BCE from 1500 BC, we can assume that our cultural seeds were laid in 2000 BCE.
    • And the benefit of socio-economic changes and massive production triggered by the iron technology gave its first fruit around 600 BCE — the Tamil Brahmi scripts.

    Culture and politics

    • The Tamil Brahmi scripts were once believed to have originated around 300 BCE, until a landmark finding in 2019 pushed the date back to 600 BCE.
    • This dating narrowed the gap between the Indus Valley civilisation and Tamilagam/South India’s Sangam Age.
    • This, and the latest findings, are politically significant.
    • The dating of the scripts, based on excavations from sites including Keeladi near Madurai, became controversial when the ASI did not go for advanced carbon dating tests.

    Prelims level: INSACOG

    Mains level: NA

    The PM has announced that the Indian SARS-CoV-2 Genomics Consortium (INSACOG) would be extended to India’s neighbouring countries.

    What is INSACOG?

    • INSACOG was established in December 2020 as a joint initiative of the Union Health Ministry of Health and Department of Biotechnology (DBT).
    • It aims to expand the whole-genome sequencing of SARS-CoV-2, the coronavirus that causes the Covid-19 disease, across India with the aim of understanding how the virus spreads and evolves.
    • It functions under the Ministry of Science and Technology with the Council for Scientific & Industrial Research (CSIR) and Indian Council of Medical Research (ICMR).

    Composition of INSACOG

    • INSACOG started out with the participation of 10 national research laboratories of the central government, and gradually expanded to a network of 38 labs.
    • It now includes private labs operating on a hub-and-spoke model.
    • These works to monitor genomic variations in SARS-CoV-2 by a sentinel sequencing effort which is facilitated by the National Centre for Disease Control (NCDC).
    • It now involves the Central Surveillance Unit (CSU) under the central government’s Integrated Disease Surveillance Programme (IDSP).

    Working of the INSACOG

    • The data from the genome sequencing laboratories is analysed as per the field data trends to study the linkages, if any, between the genomic variants and epidemiological trends.
    • INSACOG helps to understand super spreader events and outbreaks, and strengthen public health interventions across the country to help break chains of transmission.
    • Linking this data with IDSP data and the patient’s symptoms helps to better understand viral infection dynamics, and trends of morbidity and mortality.
    • The data can be linked with host genomics, immunology, clinical outcomes, and risk factors for a more comprehensive outlook.
    • Sequencing assumes added significance as the incidence of reinfections and vaccine breakthroughs increases.

    India Hypertension Control Initiative (IHCI)

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: India Hypertension Control Initiative (IHCI)

    Mains level: Non-communicable diseases burden on India

    A project called the India Hypertension Control Initiative (IHCI) finds that nearly 23% out of 2.1 million Indians have uncontrolled blood pressure.

    What is the IHCI?

    • Recognizing that hypertension is a serious, and growing, health issue in India, the Health Ministry, the ICMR, State Governments, and WHO-India began a five-year initiative to monitor and treat hypertension.
    • The programme was launched in November 2017.
    • In the first year, IHCI covered 26 districts across five States — Punjab, Kerala, Madhya Pradesh, Telangana, and Maharashtra.
    • By December 2020, IHCI was expanded to 52 districts across ten States — Andhra Pradesh (1), Chhattisgarh (2), Karnataka (2), Kerala (4), Madhya Pradesh (6), Maharashtra (13), Punjab (5), Tamil Nadu (1), Telangana (13) and West Bengal (5).

    What is Hypertension?

    • Hypertension is defined as having systolic blood pressure level greater than or equal to 140 mmHg or diastolic blood pressure level greater than or equal to 90 mmHg.
    • The definition also assumes taking anti-hypertensive medication to lower his/her blood pressure.

    Why need IHCI?

    • India has committed to a “25 by 25” goal, which aims to reduce premature mortality due to non-communicable diseases (NCDs) by 25% by 2025.
    • To achieve India’s target of a 25%, approximately 4.5 crore additional people with hypertension need to get their BP under control by 2025.

    What has the IHCI found so far?

    • Its most important discovery so far is that nearly one-fourth of (23%) patients under the programme had uncontrolled blood pressure, and 27% did not return for a follow-up in the first quarter of 2021.
    • There were an estimated 20 crore adults with hypertension in the country.
    • There weren’t enough validated high-quality digital blood pressure monitors in several health facilities, which affected accuracy of hypertension diagnosis.

    How prevalent is the problem of hypertension?

    • About one-fourth of women and men aged 40 to 49 years have hypertension.
    • Southern States have a higher prevalence of hypertension than the national average, according to the latest edition of the National Family Health Survey.
    • While 21.3% of women and 24% of men aged above 15 have hypertension in the country, the prevalence is the highest in Kerala where 32.8% men and 30.9% women have been diagnosed with hypertension.
    • Kerala is followed by Telangana where the prevalence is 31.4% in men and 26.1% in women.
