  • Serotonin Hormone causes Locust to form Swarms

    Scientists have attempted to answer an important scientific question of how and why locusts collect together by the thousands in order to make a swarm.

    Quite often, Oxytocin hormone is seen in the news for its commercial uses and associated ethical concerns. Kindly go through Oxytocin and issues over its commercial use

    What causes Locusts to form huge swarms?

    • When lone locusts happen to come near each other (looking for food) and happen to touch each other, this tactile stimulation, even just in a little area of the back limbs, causes their behaviour to change.
    • This mechanical stimulation affects a couple of nerves in the animal’s body, their behaviour changes, leading to their coming together.
    • The central nervous system of the locust, the most important among them being serotonin which regulates mood and social behaviour is the mystery behind swarms.
    • Their coming together triggers a mechanical (touch) and neurochemical (serotonin) stimulations to make crowding occur.

    What is Serotonin?

    • It is a monoamine neurotransmitter.
    • It has a popular image as a contributor to feelings of well-being and happiness.
    • Its actual biological function is complex and multifaceted, modulating cognition, reward, learning, memory, and numerous physiological processes such as vomiting and vasoconstriction.

    We’re overjoyed to announce the launch of Samachar Manthan for IAS 2021 – our flagship program for Current Affairs. 


    Absolutely no part of the IAS exam syllabus gets the level (even similar) of attention or emphasis as is received by Current Affairs. It is as ubiquitous as Oxygen on Earth, and for the exam, it’s importance is of similar magnitude. 

    In this informative article, we’ll discuss what makes Current Affairs indispensable for every stage of the IAS exam, and how to cover them and utilise them. (Check out the questions and links provided below)

    As a would-be administrator, UPSC expects you to be fully aware of happenings in the local, national and international level. You must be aware of the current and future potential/problem/challenges faced by the society, economy, polity, governance structure, etc.. It’s not just about information and knowledge, you must have a sound understanding of the interconnectedness of various issues and topics.

    Let’s start our analysis.

    Importance of  Current affairs for the exam

    Interlinkages of current issues and basics

    UPSC questions are interesting and at the same time challenging. Most of the times, UPSC uses current issues and links it with basic fundamental concepts in questions, which becomes tricky to answer. Take this question.

    Q) “The Central Administration Tribunal which was established for redressal of grievances and complaints by or against central government employees nowadays is exercising its powers as an independent judicial authority.” Explain. (UPSC 2019 Mains, GS Paper 2)

    Here you’ll be using static part i.e. CAT and its powers ( most probably from Laxminkant for Polity), but Current Affairs will come in explaining the latter part, i.e. how CAT is using its mandate to act as an independent judicial authority.

    Using Current Affairs will also give a context to this question and will bring relevance to your answer. Without interlinking it with Current Affairs your answer will be incomplete.

    Current Affairs in Prelims

    Pick up the UPSC prelims syllabus and guess what is mentioned in the first sentence. Yes, Current Affairs.

    2016 onwards UPSC Prelims exam has been dominated by Current Affairs. Questions are being compiled directly from newspapers. Even the static part asked in Pre is asked because it was related to some current event in one way or the other.

    Samachar Manthan Civilsdaily IAS Current Affairs UPSC
    Number of questions (out of 100) in UPSC prelims directly from Current Affairs.

    Importance of CA in mains

    Have a look at UPSC  previous years mains question papers and you’ll be amazed to know the number of questions asked that are directly influenced by Current Affairs. 

    Number of Questions (out of 20) asked directly from Current Affairs in UPSC Mains.

    Click here to enroll: Samachar Manthan 2021

    Even for GS Paper 1 which is considered to be dominated by static part of the syllabus from History, Culture, Geography, etc., this holds true. Look at the questions from GS Paper 1 here and observe the Current Affairs orientation.

    Q1.) What are the challenges to our cultural practices in the name of secularism? (UPSC 2019)

    Q2.) Are we losing our local identity for the global identity? Discuss.  (UPSC 2019)

    Q3.) Safeguarding the Indian art heritage is the need of the moment. Discuss. (UPSC 2018)

    Q4.) Throw light on the significance of the thoughts of Mahatma Gandhi in the present times. (UPSC 2018)

    Q5.) Discuss the factors for localization of agro-based food processing industries of North-West India. (UPSC 2019)

    Similarly, in GS Paper 2, the questions have to be interlinked with Current Affairs but a majority of them are directly from the CA. These are some of the previous year questions. 

    Q1.) ‘Too little cash, too much politics, leaves UNESCO fighting for life.’ Discuss the statement in the light of US’ withdrawal and its accusation of the cultural body as being ‘anti-Israel bias’.( UPSC 2019)

    Q2.) In the light of recent controversy regarding the use of Electronic Voting Machines (EVM), what are the challenges before the Election Commission of India to ensure the trustworthiness of elections in India?  (UPSC 2018)

    Q3.) Whether the Supreme Court Judgement (July 2018) can settle the political tussle between the Lt. Governor and elected government of Delhi? Examine. (UPSC 2018)

    In GS Paper 3, as you can see from the above table, almost 95% of the questions are from Current Affairs. (Pick up the last year’s paper)

    Importance in Essays

    Topics curated in the Essay exam may seem random and abstract but all of them are highly relevant in the context of Current Affairs. They are there because the central idea of the topic was in the news.

    Decide for yourself, these are the topics from Section B in UPSC 2019 Essay paper:

        1. South Asian societies are woven not around the state, but around their plural cultures and plural identities
        2. Neglect of primary health care and education in India are reasons for its backwardness
        3. Biased media is a real threat to Indian democracy
        4. Rise of Artificial Intelligence: the threat of jobless future or better job opportunities through reskilling and upskilling

    Importance in interview

    In Personality Tests often your opinions are asked on various issues and even from information provided in your DAF. Current Affairs make you aware of the surrounding and allow you to give practical answers to the problems faced by the country. Even till the last minute interview candidates can be seen with newspapers in their hands.

    Other than all these stages Currents Affairs important for many of the Optional papers also.


    Understanding and realising the importance of current affairs is just one part of the puzzle. You might be struggling with hundreds of other questions like- What all to read? From where to cover CA? What is important for Pre and what’s for Mains? How to make use of CA? (Yup, difficult questions)

    How to cover Current Affairs for IAS 2021?

    Samachar Manthan’s philosophy (It should be yours too!)

    1. Diversified and comprehensive coverage

    Your coverage should be extensive if not exhaustive. Various sources must be referred to, which include newspapers (The Hindu, The Indian Express, LiveMint, etc.), magazines (Yojana, Kurukshetra, EPW, Down to Earth), important websites (PIB, PRS, govt ministries, IDSA, etc.).

    At Civilsdaily it’s done by a team under Sajal Sir, that goes through six national newspapers and four magazines, daily.

    They research them thoroughly, go in and out of every news and find information relevant for UPSC. Carefully selected relevant news is analyzed and delivered in a weekly lecture spanning over 3 hours. Click to know more.

    2. Segregating important from unimportant.

    It includes two components: News you must cover and the one you can ignore. And from the important news, Prelims and Mains worthy information is extracted. 

    Important news

    One should be able to anticipate what news could form a basis for UPSC mains question. Almost all aspirants struggle to segregate important news from the junk.

    The following are the previous year questions that are directly based on the news pieces from popular publications like Down to Earth, LivemMint, Scroll, The Wire. The link of the sources has been given with the questions.

    Q1.) If an amendment bill to the Whistleblowers Act, 2011 tabled in the Parliament is passed, there may be no one left to protect.” Critically evaluate. (Source: Scroll.in)

    Q2.) What can France learn from the Indian Constitution’s approach to secularism? (Source: The Wire)

    Q3.) How can the mountain ecosystem be restored from the negative impact of development initiatives and tourism? (Source: Down To Earth)

    Q4.) The public expenditure management is a challenge to the government of India in the context of budget-making during the post-liberalization period. Clarify it. (Source: Livemint)

    What to ignore?

    While your coverage should be comprehensive, there is news which you should ignore else you’re duplicating your efforts or wasting your time or doing both, and hence, bringing inefficiency to your preparation.

    Examples: Op-ed with repeated themes on COVID and Fiscal stimulus.

    Then there are news items like these, as given below. Have a look at them. Ignore them.

    Example 1- Retail inflation rises to 7.59% in January on higher food prices

    Example 2- India’s services exports rises 7.0% in January 2020

    Example 3- If the lockdown is not lifted, there may be defiance on a larger scale than at present

    3. Extracting UPSC relevant information from the news

    Now, this is the Holy Grail. If you fail to extract UPSC relevant information from the important current affairs, all your effort will go in vain. It is the most important skill and takes time to perfect it. Even students with multiple UPSC interview experiences struggle at this stage.

    On how to do it, take the example of this news regarding Reverse Repo Rate. 

    News: How the reverse repo rate became the benchmark interest rate in the Indian economy?

    The following are the mains and prelims worth topics that can be extracted from this single news item.

    Mains relevant: Critically examine the efficacy of reverse repo rate as the benchmark interest rate in the Indian economy. “

    Prelims relevant: Reverse repo rate, LTRO, Benchmark interest rate

    4. Focus on Conceptual clarity

    Rather than just learning and mugging up the information, the focus should be on understanding various dimensions, interlinkages, related issues, and conceptual clarity w.r.t. static parts as well.

    5. Utilising information from Current Affairs.

    It’s the ultimate purpose of doing Current Affairs. And being able to do this, you must be very regular with CA-based Mains answer writing, solving prelims questions and identifying errors and making required changes.

    (Current Affairs based Mains answer writing is an important component of Samachar Manthan 2021)

    Answer writing must become second nature of an IAS aspirant. “Rome wasn’t built in a day, but they were laying bricks every hour.

    6. Evaluation and active learning

    Getting your views (in the form of answers) evaluated is an important step. You’ll not only know what mistakes you are committing but you’ll also learn important answer writing skills. Answer enhancement must be the focus (it’s in Samachar Manthan 2021).

    (Through our platform Habitat and Civilsdaily’s Handholding, we’ll ensure that you are right on track.)

  • India launches campaign brochure for UNSC seat

    India has launched its campaign brochure ahead of elections for five non-permanent members of UNSC.

    Practice question for mains:

    Q. By any calculus, India will qualify for UNSC permanent seat. Analyse.

    India’s agenda for UNSC

    The normal process of international governance has been under increasing strain as frictions have increased. Traditional and non-traditional security challenges continue to grow unchecked. India will highlight:

    • International terrorism
    • UN reforms and Security Council expansion, and
    • Streamlining the world body’s peacekeeping operations
    • Various technological initiatives

    India and UNSC

    • India is guaranteed a place in the UNSC as it is the sole candidate for Asia-Pacific but needs two-thirds of the 193-member General Assembly to vote in its favour in a secret ballot scheduled this month in New York.
    • While India is expected to sail through with the 129 votes required for the seat, the government is setting its sights on much higher numbers than that ahead of the election.
    • In 2010, when India stood for the UNSC seat of 2011-2012, it won 187 of the 190 votes polled.

    Streamlining new NORMS

    • This will be the eighth time India will occupy a non-permanent UNSC seat, with its last stint in 2011-2012.
    • India’s overall objective during this tenure in the UN Security Council will be the achievement of N.O.R.M.S: a New Orientation for a Reformed Multilateral System.

    Non-permanent membership  isn’t a cup of tea

    • The government launched its plan for the UNSC seat as far back as 2013, officials said, with a keen eye on 2021, and the year that will mark its 75th year of Independence.
    • To our good fortune, the Islamic Republic of Afghanistan agreed, in a gesture to our friendship, to step aside for the 2021-22 seats.
    • The next big challenge was to pursue the Asia-Pacific grouping nomination without any last-minute contenders being propped up against India.
    • While diplomacy between capitals certainly helps, the vote had to be tied down by negotiations on the ground.
    • India was able to win a unanimous endorsement from the 55-nation grouping that included both China and Pakistan, in June 2019.

    Back2Basics: United Nations Security Council

    • The UNSC is one of the six principal organs of the United Nations and is charged with the maintenance of international peace and security.
    • Its powers include the establishment of peacekeeping operations, the establishment of international sanctions, and the authorization of military action through Security Council resolutions.
    • It is the only UN body with the authority to issue binding resolutions to member states.
    • The Security Council consists of fifteen members. Russia, the United Kingdom, France, China, and the United States—serve as the body’s five permanent members.
    • These permanent members can veto any substantive Security Council resolution, including those on the admission of new member states or candidates for Secretary-General.
    • The Security Council also has 10 non-permanent members, elected on a regional basis to serve two-year terms. The body’s presidency rotates monthly among its members.

  • Near-Earth Object (NEO) 163348

    NASA announced that a giant asteroid is expected to pass Earth at a safe distance, today.

    Do you remember Osiris-Rex spacecraft of NASA? It is the only spacecraft to touch an asteroid called ‘Bennu’. NASA has brought back comet dust and solar wind particles before, but never asteroid samples.

    This makes it a landmark feat and thus a hotspot for UPSC prelims.

    What are NEOs?

    • NASA defines NEOs as comets and asteroids nudged by the gravitational attraction of nearby planets into orbits which allows them to enter the Earth’s neighbourhood.
    • These objects are composed mostly of water ice with embedded dust particles.
    • NEOs occasionally approach close to the Earth as they orbit the Sun.
    • NASA’s Center for Near-Earth Object Study (CNEOS) determines the times and distances of these objects as and when their approach to the Earth is close.

    Significances of NEOs

    • The scientific interest in comets and asteroids is largely due to their status as relatively unchanged remnant debris from the solar system formation process over 4.6 billion years ago.
    • Therefore, these NEOs offer scientists clues about the chemical mixture from the planets formed.
    • Significantly, among all the causes that will eventually cause the extinction of life on Earth, an asteroid hit is widely acknowledged as one of the likeliest.
    • Over the years, scientists have suggested different ways to ward off such a hit, such as blowing up the asteroid before it reaches Earth, or deflecting it off its Earth-bound course by hitting it with a spacecraft.

    About 163348 (2002 NN4)

    • A Near-Earth Object (NEO), the asteroid is called 163348 (2002 NN4) and is classified as a Potentially Hazardous Asteroid (PHA).
    • Asteroids with a minimum orbit intersection distance (MOID) of about 0.05 (AU is the distance between the Earth and the Sun and is roughly 150 million km) or less are considered PHAs.
    • This distance is about 7,480,000 km or less and an absolute magnitude (H) of 22 (smaller than about 150 m or 500 feet in diameter).
  • ‘Race to Zero’ campaign

    The UN has launched the “Race to Zero” campaign ahead of delayed COP 26 Climate Talks.

    Possible question for prelims:

    The ‘Race to Zero’ campaign often seen in news is related to zeroing: Global Hunger/Carbon Emission/HR violations/None of these.

     ‘Race to Zero’ campaign

    • The campaign aims to codify commitments made via the Climate Ambition Alliance (CAA), which launched ahead of last year’s COP25 in Madrid.
    • It encourages countries, companies, and other entities to deliver structured net-zero greenhouse-gas emission pledges by the time the talks begin.
    • This messaging for the campaign — carried out under the aegis of the UNFCCC— seeks to emphasise the potential for non-state actors to raise climate ambition.
    • The campaign refers to these as ‘real economy actors’, noting they “cover just over half the gross domestic product, a quarter of global CO2 emissions and over 2.6 billion people”.

    About the Climate Ambition Alliance

    • The CAA currently includes 120 nations and several other private players that have committed to achieving zero net greenhouse gas emissions by 2050.
    • Signatories are responsible for 23 per cent of current greenhouse-gas emissions worldwide and 53 per cent of global GDP.

    What Are the Criteria?

    • The minimum criteria for establishing a recognized pledge were developed through dialogues coordinated by Oxford University.
    • The pledges must include a clear net-zero target date no later than 2050, they must also begin immediately and include interim targets.
    • Much like the Paris Agreement itself, the criteria are designed to strengthen over time, but they begin at a level that reflects current best practices.

    Issue over offsetting

    • Offsets are emission-reductions generated outside a company’s own operations, and they are used in both compliance programs to meet mandated emission caps (“cap and trade”) and involuntary programs to reduce a company’s overall impact (voluntary carbon markets).
    • The Race to Zero criteria emphasizes that if offsets are ultimately recognized, they must only be used to neutralize residual emissions that can’t be eliminated internally – at least not immediately.
  • The China conundrum

    India-China border issue and the latest standoff in Ladakh has forced India to consider the lasting solution to the problem. This article explains China’s anti-India strategy. And options available with India in the face of aggression are also considered.

    LAC: the reason for frequent face-offs

    • The debate has persisted whether it was China’s National Highway 219 cutting across Aksai Chin or Nehru’s “forward policy” which constituted the actual reason for the Sino-Indian border-conflict of 1962.
    • After declaring a unilateral ceasefire on November 20, troops of the Peoples Liberation Army (PLA) withdrew 20 kms behind what China described as the “line of actual control” (LAC).
    • The LAC generally conformed to the British-negotiated McMahon Line.
    • In the west, the Chinese stuck to their 1959 claim-line in Ladakh, retaining physical control of the 14,700 sq km Aksai Chin.
    • The 1962 ceasefire line became the de facto Sino-Indian border.
    • But in a bizarre reality, both sides visualised their own version of the LAC, but neither marked it on the ground; nor were maps exchanged.
    • This has inevitably led to frequent face-offs.

    So, what were the steps taken the resolve the border issue after 1962?

    • Post-conflict, it is customary for belligerents to undertake early negotiations, in order to establish stable peace and eliminate the casus belli.
    • Strangely, in the Sino-Indian context, it took 25 years and a serious military confrontation in 1987 to trigger a dialogue.
    • The dialogue led the two countries to sign the first-ever Sino-Indian Border Peace and Tranquility Agreement (BPTA) in 1993.
    • Indian diplomats claim that this has helped maintain “mutual and equal security”, while the bilateral relationship has progressed in other spheres.
    • And yet, the failure to negotiate a boundary settlement after 22 meetings of special representatives of the two countries cannot be seen as anything but a failure of statesmanship and diplomacy.

    Now, let’s analyse China’s anti-India strategy and how LAC and Pakistan problem fits into it

    • China’s post-civil war leadership had conceived an early vision of the country’s future.
    • Ambitious and realist in scope, this strategy visualised China attaining, in the fullness of time, great-power status and acquiring a nuclear-arsenal.
    • Since the vision saw no room for an Asian rival, neutralising India became a priority.
    • It was for this specific purpose, that Pakistan was enlisted in 1963 as a partner.
    • In China’s anti-India strategy, Pakistan has played an invaluable role by sustaining a “hot” border and holding out the threat of a two-front war.
    • In China’s grand-strategy, an undefined LAC has become a vital instrumentality to embarrass and keep India off-balance through periodic transgressions.
    • These pre-meditated “land-grabs”, blunt messages of intimidation and dominance, also constitute a political “pressure-point” for New Delhi.

    Possibility of escalation into shooting war

    • While Indian troops have, so far, shown courage and restraint in these ridiculous brawls with the PLA.
    • But there is no guarantee that in a future melee, a punch on the nose will not invite a bullet in response.
    • In such circumstances, rapid escalation into a “shooting-war” cannot be ruled out.
    • Thereafter, should either side face a major military set-back, resort to nuclear “first-use” would pose a serious temptation.

    What are the options available with India?

    • For reasons of national security as well as self-respect, India cannot continue to remain in a “reactive mode” to Chinese provocations and it is time to respond in kind.
    • Since India’s choices vis-à-vis China are circumscribed by the asymmetry in comprehensive national power, resort must be sought in realpolitik.
    • According to theorist Kenneth Waltz, just as nature abhors a vacuum, international politics abhors an imbalance of power, and when faced with hegemonic threats, states must seek security in one of three options: 1) Increase their own strength, 2) ally with others to restore power-balance, 3) as a last resort, jump on the hegemon’s bandwagon.

    India’s decision-makers can start by posing this question to the military: “For how long do you have the wherewithal to sustain a combat against two adversaries simultaneously?” Depending on the response, they can consider the following 2 options.

    1. Alliance with the USA

    • Nehru, when faced with an aggressive China in 1962, asked support from the USA.
    •  Indira Gandhi in the run-up to the 1971 war with Pakistan asked support from the USSR.
    • Both had no qualms of jettisoning the shibboleth of “non-alignment” and seeking support from the USA and USSR respectively.
    • Today, India has greater freedom of action and many options to restore the balance of power vis-à-vis China.
    • Xi Jinping has opened multiple fronts — apart from the COVID-19 controversy — across the South China Sea, South East Asia, Hong Kong, Taiwan and South Asia.
    • Donald Trump is burning his bridges with China.
    • In the world of realpolitik, self-interest trumps all and India must find friends where it can.
    • Given China’s vulnerabilities in the Indian Ocean and the real possibility of America losing its strategic foothold in Diego Garcia, India has a great deal to offer as a friend, partner or even an ally; with or without the Quad.

    2. Accommodation with China

    •  If ideological or other reasons preclude the building of a power-balancing alliance, coming to an honourable accommodation with China remains a pragmatic option.
    • Zhou Enlai’s proposal of 1960 — repeated by Deng Xiaoping in 1982 — is worth re-examining in the harsh light of reality.
    • The price of finding a modus vivendi [an arrangement or agreement allowing conflicting parties to coexist peacefully]for the Sino-Indian border dispute may be worth paying if it neutralises two adversaries at one stroke and buys lasting peace.

    Consider the question “In the harsh light of reality and faced with aggression from its neighbour, India has to ally with other powers to restore the balance of power. Examine.”

    Conclusion

    Neither option will be easy to “sell”. However, India cannot afford to continue with the current situation for long and must choose one of the options to end the to find the solution.

  • Electrolytic splitting of Water

    Scientists from The Centre for Nano and Soft Matter Sciences (CeNS), an autonomous institute of the Department of Science and Technology (DST), have found out a low cost and efficient way to generate hydrogen from water using Molybdenum dioxide as a catalyst.

    Practice question for mains:

    Q. Hydrogen is the future of clean and sustainable energy. Discuss.

    Electrolytic splitting of water

    • Electrolysis of water is the decomposition of water into oxygen and hydrogen gas due to the passage of an electric current.
    • This technique can be used to make hydrogen gas, the main component of hydrogen fuel, and breathable oxygen gas, or can mix the two into oxyhydrogen, which is also usable as fuel, though more volatile and dangerous.
    • It is a promising method to generate hydrogen but requires energy input that can be brought down in the presence of a catalyst.

    Using Molybdenum Catalyst

    • The scientists have shown that Molybdenum dioxide (MoO2) nanomaterials annealed in hydrogen atmosphere can act as efficient catalysts to reduce the energy input to bring about water splitting into Hydrogen.
    • Molybdenum dioxide has the potential to replace the currently employed catalyst platinum, which is expensive and has limited resources.
    • MoO2 is a conducting metal oxide that is one of the low-cost catalysts with good efficiency and stability for hydrogen evolution.
    • The catalyst is highly stable for a longer duration of reaction with sustained hydrogen evolution from water.
    • About 80 % efficient conversion of electrical energy into hydrogen has been achieved using this catalyst.

    Significance

    • Hydrogen is considered as the future of clean and sustainable energy as it can be generated from water and produces water on energy generation without any carbon footprint.
    • Hydrogen can be directly used as a fuel similar to natural gas or as input for fuel cells to generate electricity.
    • It is the future energy for a clean environment and an alternative to fossil fuels, underlining the necessity of low-cost catalysts for its production.
