  • Cultivation of ‘Wild’ Arunachal Kiwi

    Recently, the ‘Wild’ Arunachal Kiwi has received organic certification by the Mission Organic Value Chain Development for the North East Region.

    Try this PYQ:

    Q.Among the agricultural commodities imported by India, which one of the following accounts for the highest imports in terms of value in the last five years?

    (a) Spices

    (b) Fresh fruits

    (c) Pulses

    (d) Vegetable oils

    Arunachal Kiwi

    • The kiwifruit (Actinidia deliciosa Chev.) is a deciduous fruiting vine native to Yangtze River valley of south and central China.
    • In Arunachal Pradesh, a domesticated variety of kiwi was introduced as a commercial fruit only in 2000.
    • The Ziro Valley specifically located at 1,500-2,000 metres above sea level is the most ideal for kiwi.
    • It is also called “China’s miracle fruit” and “Horticulture wonder of New Zealand”.

    Benefits of certification

    • Certification helps producers and handlers; they receive premium prices for the products and have access to fast-growing, local, regional and international markets.

    Organic certification in India

    • An agricultural practise/product is considered organic when there are no chemical fertilizers or pesticides involved in its cultivation process.
    • Such certifications in India can be obtained after a strict scientific assessment done by the regulatory body, Agricultural and Processed Food Products Export Development Authority (APEDA).

  • Zebrafish and its heart regeneration capacity

    Indian scientists have used the Zebrafish model and identified its genes that can promote heart regeneration.

    Try this PYQ:

    Q.With reference to India’s Biodiversity, Ceylon frogmouth, Coppersmith Barbet, Gray-chinned minivet and White-throated redstart are-

    (a) Birds

    (b) Primates

    (c) Reptiles

    (d) Amphibians

    Zebrafish

    • Zebrafish is a small (2-3 cm long) freshwater fish found in the tropical and subtropical regions.
    • The fish is native to South Asia’s Indo-Gangetic plains, where they are mostly found in the paddy fields and even in stagnant water and streams.
    • The fish become adults at three months and survive 2-3 years in a laboratory condition.
    • Its unique characteristics lie in its transparency during its embryonic stages, allowing observing all organs, including beating heart and blood circulation.

    Ability to heal their heart

    • The ability of Zebrafish to heal their heart after injury makes them an attractive model to investigate mechanisms governing the regenerative process.
    • Researchers worldwide are actively working to understand the mechanism behind the heart regeneration in Zebrafish for the last two decades.
    • Years of efforts have helped them identify the cellular communication network factor 2a (ccn2a), a gene that can promote heart regeneration by enhancing cardiomyocyte proliferation.
    • They have also observed that this gene resolves the transient collagenous fibrotic scar resulting in faster regeneration.

    Significance for humans

    • Cardiovascular diseases are the number 1 cause of deaths globally, taking an estimated 17.9 million lives each year, according to the World Health Organisation.
    • Humans cannot regenerate their hearts upon myocardial damage and a person who suffered a heart attack cannot functionally heal the damaged heart muscle, resulting in reduced pumping efficiency.
    • While on the other hand, this unique fish has the full potential to regenerate its heart and restore its function after injury.
    • Till now, there is no treatment available to restore the damaged heart function in humans. Hence scientists have sought to decode the heart regeneration processes using this model animal.

  • In new: Annapurna Idol

    PM has announced that an ancient idol of the goddess Annapurna, stolen from India about a century ago, is being brought back from Canada.

    Must revise: Gandhara and Mathura school of Art

    [Static Revision] Chapter 6 | Post Mauryan Period (200BC to 300AD)

    Annapurna Idol

    • Annapurna, also spelt Annapoorna, is the goddess of food.
    • This 18th-century idol, carved in the Benares was stolen from a temple of Varanasi and smuggled out around 100 years ago somewhere around 1913.
    • Now is part of the University of Regina, Canada’s collection at the MacKenzie Art Gallery.
    • The idol holds a bowl of kheer in one hand and a spoon in the other.

  • RT-LAMP: a new technology for detecting COVID-19

    Indian Council of Medical Research has recently validated the LAMP technology for COVID-19 testing.

    What is RT-LAMP?

    • RT-LAMP stands for Reverse Transcriptase loop-mediated isothermal amplification) technology.
    • Agappe Diagnostics has recently developed the technology indigenously, and their kit has been validated and approved by the ICMR for marketing.
    • It is named LUME Screen nCoV.

    How does it work?

    • RT-LAMP technology is a one-step nucleic acid amplification method to multiply specific sequences of RNA of the coronavirus.
    • The RNA is first made into cDNA (copy DNA) by the usual reverse transcription. Then, the DNA is amplified by the LAMP technique.

    Current method

    • •The current method diagnosis is the real time reverse transcription polymerase chain reaction (RT-PCR) test which detects the presence of viral nucleic acids in nasopharyngeal swab samples.
    • But it has certain shortcomings.
    • The test requires complex and costly equipment. It requires extensive training for potential users.

    Benefits of LAMP over RT-PCR

    • The LAMP technology is superior to the PCR technology–based COVID-19 kits where specificity is around 95% only.
    • As the specificity and sensitivity of the test is about 95%, there is a possibility of false negative results.
    • The turnaround time is about 10 hours, so that the result will be available only by the next day.
    • In remote places, the turnaround time further increases depending on the distance the samples need to travel.
    • In short, the RT-PCR does not have the capacity to keep pace with the increasing demand.
    • The LAMP technology does not need laborious preparation as in the case of RT-PCR. LAMP is cost effective and does not need complex expensive equipment.

     

  • Brain Electrical Oscillation Signature Profiling (BEOSP)

    A brain electrical oscillation signature profiling (BEOSP) test will be conducted on the convicts of the alleged rape and murder in Hathras, Uttar Pradesh.

    Note: According to Article 20(3) of the Indian constitution, no person accused of any offence shall be compelled to be a witness against himself. The privilege against self-incrimination is a fundamental canon of common criminal law jurisprudence.

    What is the BEOSP test?

    • BEOSP also known as brain fingerprinting is a neuro-psychological method of interrogation in which the accuser’s participation in the crime is investigated by studying their brain’s response.
    • The BEOSP test is carried out via a process known as an electroencephalogram, conducted to study the electrical behaviour of the human brain.
    • Under this test, the consent of the accused is first taken and they are then made to wear caps with dozens of electrodes attached to them.
    • The accused are then shown visuals or played audio clips related to the crime to check if there is any triggering of neurons in their brains which then generate brainwaves.
    • The test results are then studied to determine the participation of the accused in a crime.

    What differentiates a BEOSP test from a polygraph or a lie detector?

    • The BEOSP procedure does not involve a question-answer session with the accused and is rather a neuro psychological study of their brain.
    • In a polygraph test, the accused person’s physiological indicators are taken into account which includes blood pressure, pulse rate, respiration and skin conductivity.
    • While a person might be able to control their pulse rate and BP even in times of distress, a BEOSP test

    Can these tests be admitted as evidence?

    • Not as a standalone, a/c to the 2010 Supreme Court judgment in the Selvi v. State of Karnataka case.
    • The bench observed that narco analysis, polygraph and brain mapping tests cannot be forced upon any individual without their consent and the test results cannot be admitted solely as evidence.
    • However, any information or material discovered during the tests can be made part of the evidence, observed the bench.

  • BrahMos Missiles and their significance for Armed Forces

    India’s Armed forces are conducting back-to-back tests of various versions of BrahMos missile.

    Take a quick look at India’s missile arsenal:

    [Prelims Spotlight] Missiles

    The BrahMos Missiles

    • A combination of the names of Brahmaputra and Moskva rivers, BrahMos missiles are designed, developed and produced by BrahMos Aerospace, a joint venture company set up by DRDO and Mashinostroyenia of Russia.
    • It is a two-stage missile with a solid propellant booster as the first stage and liquid ramjet as the second stage.
    • The cruise missiles like BrahMos are a type of systems known as the ‘standoff range weapons’ which are fired from a range sufficient to allow the attacker to evade defensive fire from the adversary.
    • These weapons are in the arsenal of most major militaries in the world.
    • The versions of the BrahMos that are being tested have an extended range of around 400 km, as compared to its initial range of 290 km, with more versions of higher ranges currently under development.

    Various versions

    • Various versions of the BrahMos, including those which can be fired from land, warships, submarines and Sukhoi-30 fighter jets have already been developed and successfully tested in the past.
    • The earliest versions of the ship launched BrahMos and land-based system are in service of the Indian Navy and the Indian Army since 2005 and 2007 respectively.

  • Sea sparkle: Bloom of Noctiluca Scintillans

    The blooms of Noctiluca Scintillans, commonly known as “sea sparkle” are being witnessed along the coasts of Maharashtra and Karnataka.

    A stand-alone species being mentioned in the news for the first time find their way into the prelims. Note this down.

    Noctiluca Scintillans

    • Scintillans is a bioluminescent specie that brightens the seawater during the night.
    • It grazes on other micro-organisms such as larvae, fish eggs, and diatoms. But the unicellular phytoplankton that lives inside it can photosynthesize, turning sunlight into energy.
    • They help their host cell survive even when food was scarce.
    • Thus, N. Scintillans acts as both a plant and an animal

    Threats posed

    • According to marine experts, the phenomenon is an indicator of climate change.
    • While smaller blooms may be harmless, slow-moving larger blooms may have an impact on deep-sea fishes.
    • The toxic blooms of N. Scintillans were linked to massive fish and marine invertebrate kills.
    • Though the species does not produce a toxin, it was found to accumulate toxic levels of ammonia, which is then excreted into the surrounding waters, possibly acting as the killing agent in blooms.
    • They have displaced microscopic algae called diatoms, which form the basis of the marine food chain. This has deprived food for the planktivorous fish.

    Back2Basics: Bioluminescence

    • It is the property of a living organism to produce and emit light.
    • Animals, plants, fungi and bacteria show bioluminescence. A remarkable diversity of marine animals and microbes are able to produce their own light.
    • It is found in many marine organisms such as bacteria, algae, jellyfish, worms, crustaceans, sea stars, fish and sharks.
    • Luminescence is generally higher in deep-living and planktonic organisms than in shallow species.

  • What is Federated Learning?

    An improvement in a Machine Learning (ML) model, called ‘federated learning’, is said to enable companies to develop new ways of collecting anonymous data without compromising their privacy.

    Data privacy is the right of a citizen to have control over how personal information is collected and used. Data protection is a subset Right of Privacy under Article 21 of the Indian Constitution.

    What is ‘federated learning’?

    • Federated learning is an ML method used to train an algorithm across multiple decentralised devices or servers holding data samples.
    • It doesn’t exchange data with the devices, meaning there is no central dataset or server that stores the information.
    • Standard ML models require all data to be centralised in a single server. Implementation of federated learning eliminates the need for maintaining a storage hub.
    • The term was first introduced in a 2016 Google study titled ‘Communication-efficient learning of deep networks from decentralized data.’
    • Google emphasised mobile phones and tablets, stating that modern devices contain special features like speech recognition and image models that can store large amounts of data.
    • Since then, Google has used the technique is various products, including Gboard, which provides text and phrase suggestions to the keyboard.

    How this works

    • Federated learning aims to train an algorithm, like deep neural networks, on multiple local datasets contained in local nodes, without explicitly exchanging data.
    • The general principle involves simply exchanging parameters between these nodes. Parameters include a number of federated learning rounds, the total number of nodes, and learning rate.
    • The distinct advantage of the model is its ability to reduce privacy and security risks by limiting the attack surface to only the device, rather than the device and the cloud, Google stated in the study.

    Why need such technology?

    • Smart home devices like speakers and smartwatches collect and share data with other devices and systems over the network.
    • These Internet of Things (IoT) devices are equipped with sensors and software that store a user’s private information like body measurements and location.
    • This large chunk of stored data is used by the device makers to improve their products and services.

    Applications

    • Federated learning is said to have application in healthcare, where hospitals and pharmaceutical companies can exchange data for treating diseases without sharing private clinical information.

  • One nation One election

    Prime Minister once again raised the pitch for “One Nation, One Election” and a single voter list for all to prevent the impact of the model code of conduct on development works due to frequent elections.

    Try this question:

    Q.Discuss how a common electoral roll and simultaneous elections are ways to save the enormous amount of effort and expenditure on Elections in India. Also discuss the centralizing tendency behind the idea.

    Elections in India

    • Currently, elections to the state assemblies and the Lok Sabha are held separately — that is whenever the incumbent government’s five-year term ends or whenever it is dissolved due to various reasons.
    • This applies to both the state legislatures and the Lok Sabha. The terms of Legislative Assemblies and the Lok Sabha may not synchronize with one another.
    • For instance, Rajasthan faced elections in late 2018, whereas Tamil Nadu will go to elections only in 2021.

    Simultaneous Elections

    • But the idea of “One Nation, One Election” envisages a system where elections to all states and the Lok Sabha will have to be held simultaneously.
    • This will involve the restructuring of the Indian election cycle in a manner that elections to the states and the centre synchronize.
    • This would mean that the voters will cast their vote for electing members of the LS and the state assemblies on a single day, at the same time (or in a phased manner as the case may be).

    Birth of the Idea: A backgrounder

    • Simultaneous elections are not new to India. They were the norm until 1967.
    • But following dissolution of some Legislative Assemblies in 1968 and 1969 and that of the Lok Sabha in December 1970, elections to State Assemblies and Parliament have been held separately.
    • The idea of reverting to simultaneous polls was mooted in the annual report of the Election Commission in 1983.
    • The Law Commission’s Report also referred to it in 1999.
    • After PM floated the idea once again in 2016, the NITI Aayog prepared a working paper on the subject in January 2017.

    What are the proposals under it?

    There were two proposals to conduct elections synchronization in two batches.

    • One proposal was to make the shift to simultaneous polls in a phased manner, where general elections, of few States and UT may be synchronised in 2019.
    • For such a synchronization to happen, besides political consensus and extension of term up to six months in some states, amendments to the Constitution have to be made.
    • Elections to the remaining States and UTs with will be synchronised by the end of 2021.
    • Thereafter, elections to the Lok Sabha, all the State Legislative Assemblies and Union Territories (with legislatures) will be held simultaneously from 2024.

    Advantages of simultaneous elections

    • Reduce cost: The cost of an election has two components – one, expenditure incurred by the Election Commission and two, expenditure incurred by the political parties. A large number of government employees and public buildings are diverted from their regular responsibilities for election duties. Supporters of the simultaneous elections argue that it will reduce election expenditure in terms of finance and reduce diversion of human resources for election duties.
    • Reduce disruption due to MCC: Model Code of Conduct (MCC) comes into operation during election season. MCC is seen as an obstacle to the government service delivery mechanism. Simultaneous elections may reduce such disruption.
    • Reduce populism: During elections, political convenience takes precedence over public interest. To lure voters, political parties concede to popular demands without any consideration to public interest. Simultaneous elections reduce such opportunity for political parties.
    • National prespective: Simultaneous election promotes national perspective over the regional perspective. This is important for the unity of the country.
    • Strengthen National parties: Since it promotes national perspective, simultaneous elections strengthen national parties. This reduces mushrooming growth of political parties based on narrow vote bank politics.
    • Strengthens federalism: Simultaneous elections bring States on par with the Center. If the elections are to be held simultaneously once in five years, the elected state governments cannot be dismissed easily. This reduces the anomalies created by the Article 356 (President’s Rule) of the Indian constitution and hence, it strengthens federalism.
    • Stability: The simultaneous election once in five years provides stability to the governments. It allows the government to take difficult and harsh decision in larger public interest.

    Arguments against simultaneous elections

    • No guarantee that expenditure of the political parties will reduce: Simultaneous elections may reduce the expenditure incurred by the Election Commission. But there is no guarantee that expenditure of the political parties will reduce. Political parties may spend entire fund at once rather than in phases.
    • Reduce importance of state elections: Center and States are equal and sovereign within their jurisdiction. Simultaneous elections may reduce the importance of state elections. Thus it affects the concept of federalism.
    • Violates Article 83(2) and Article 172 : Article 83(2) and Article 172 of the Constitution requires that the Lok Sabha and State legislatures be in existence for five years from the date of its first meeting, “unless dissolved earlier”. Simultaneous elections ignore this phrase, as there would be no opportunity to dissolve Lok Sabha or State Assemblies.
    • Negates NCM: A government can be in power as long as it enjoys the confidence of Parliament. Simultaneous elections can work only if governments last for a fixed tenure of five years regardless of confidence of Parliament. It negates the concept of ‘no confidence motion’ – an important tool for legislative control over the executive.
    • Keep Government on toes: Elections are an important part of representative democracy. Simultaneous elections with fixed tenure of five years curtail people’s right to express their confidence or displeasure on the government.
    • Ignores diversity: Simultaneous elections will relegate local issues or issues of state importance to the background. This completely ignores the diversity of the country.
    • Logistical challenge: Holding simultaneous election once in five years may also face logistical challenges. For the free and fair conduct of the elections, security forces need to be deployed in large numbers. Given the current strength of security personnel, this may be a challenging task.

    Way forward

    • There needs to be a consensus and all hands on the deck to see whether the country suits for simultaneous elections.
    • All political parties should at least cooperate in debating this issue, once the debate starts, the public opinion can be taken into consideration.
    • India being a mature democracy, can then follows the outcome of the deliberation.

    Shekhawat solution

    • The former vice-president Bhairon Singh Shekhawat proposed a solution. He called for a review of provisions of the no-confidence motion.
    • He suggested that no-confidence motion must mandatorily be accompanied by an alternative government formation plan. This prevents premature dissolution of Lok Sabha on account of political instability.
    • But critics point out that, this solution will take away people’s right to elect or dismiss a government.

    Conclusion

    • The constitution of India has essentially prescribed a federal structure of state governance.
    • As we are aware that there are several levels of government such as Lok Sabha and the Rajya Sabha besides, state governments, Municipal Corporations and the Panchayats, which are forms of local governance.
    • As a result the entire power is not concentrated with one government.
    • But One Nation, One Election can lead to such concentration of power in a single hand.
    • So the new government needs to ensure such vast power is not gathered by a single domain through One Nation, One Election.

  • What are Negative-Yield Bonds?

    China recently sold negative-yield debt for the first time, and this saw high demand from investors across Europe.

    Try this PYQ:

    Q.Which of the following is issued by registered foreign portfolio investors to overseas investors who want to be part of the Indian stock market without registering themselves directly?

    (a) Certificate of Deposit

    (b) Commercial Paper

    (c) Promissory Note

    (d) Participatory Note

    What are Negative-Yield Bonds?

    • These are debt instruments that offer to pay the investor a maturity amount lower than the purchase price of the bond.
    • These are generally issued by central banks or governments, and investors pay interest to the borrower to keep their money with them.

    Why do investors buy them?

    • Negative-yield bonds attract investments during times of stress and uncertainty as investors look to protect their capital from significant erosion.
    • At a time when the world is battling the Covid-19 pandemic and interest rates in developed markets across Europe are much lower.
    • Hence, investors are looking for relatively better-yielding debt instruments to safeguard their interests.

    Why is there a huge demand?

    • While Europe, the US and other parts of the world are facing a second wave of Covid-19 cases, China has demonstrated that it has controlled the spread of the pandemic and is therefore seen as a more stable region.
    • Many feel that European investors are also looking to increase their exposure in China, and hence there is a huge demand for these bonds.
    • The fact that the 10-year and 15-year bonds are offering positive returns is a big attraction at a time when interest rates in Europe have dropped significantly.
    • As against minus —0.15% yield on the 5-year bond issued by China, the yields offered in safe European bonds are much lower, between –0.5% and —0.75%.
