  • China’s EAST Tokamak Device

    China’s Experimental Advanced Superconducting Tokamak (EAST), which mimics the energy generation process of the sun, set a new record.

    What is China’s ‘artificial sun’ EAST?

    • The Experimental Advanced Superconducting Tokamak (EAST) reactor is an advanced nuclear fusion experimental research device.
    • The purpose of the artificial sun is to replicate the process of nuclear fusion, which is the same reaction that powers the sun.
    • The EAST is one of three major domestic tokamaks that are presently being operated across the country.
    • Apart from the EAST, China is currently operating the HL-2A reactor as well as J-TEXT.
    • Since it first became operational in 2006, the EAST has set several records for the duration of confinement of exceedingly hot plasma.
    • The EAST project is part of the International Thermonuclear Experimental Reactor (ITER) facility, which will become the world’s largest nuclear fusion reactor when it becomes operational in 2035.
    • The project includes the contributions of several countries, including India, South Korea, Japan, Russia and the United States.

    How does the ‘artificial sun’ EAST work?

    • The EAST Tokamak device is designed to replicate the nuclear fusion process carried out by the sun and stars.
    • Nuclear fusion is a process through which high levels of energy are produced without generating large quantities of waste.
    • Previously, energy was produced through nuclear fission — a process in which the nucleus of a heavy atom was split into two or more nuclei of lighter atoms.

    Fission vs. Fusion

    • While fission is an easier process to carry out, it generates far more nuclear waste.
    • Unlike fission, fusion also does not emit greenhouse gases and is considered a safer process with a lower risk of accidents.
    • Once mastered, nuclear fusion could potentially provide unlimited clean energy and very low costs.

    But what is Fusion?

    • For nuclear fusion to occur, tremendous heat and pressure are applied on hydrogen atoms so that they fuse together. `
    • The nuclei of deuterium and tritium — both found in hydrogen — are made to fuse together to create a helium nucleus, a neutron along with a whole lot of energy.
    • Fuel is heated to temperatures of over 150 million degrees C so that it forms a hot plasma “soup” of subatomic particles.
    • With the help of a strong magnetic field, the plasma is kept away from the walls of the reactor to ensure it does not cool down and lose its potential to generate large amounts of energy.
    • The plasma is confined for long durations for fusion to take place.

    What is the latest record and why does it matter?

    • The EAST reactor set a new record on Friday when it achieved a plasma temperature of 216 million degrees Fahrenheit and also managed to run for 20 seconds at 288 million degrees Fahrenheit.
    • To put this in perspective, the sun’s core only reaches about 15 million degrees Celsius, which means the reactor was able to touch temperatures that are 10 times hotter than that.
    • The next goal for the scientists behind the experimental reactor is to maintain the high temperature for a long period of time. Previously, the EAST had reached a record temperature of 100 million degrees Celsius in 2018.

    China is not the only

    • But China is not the only country that has achieved high plasma temperatures.
    • In 2020, South Korea’s KSTAR reactor set a new record by maintaining a plasma temperature of over 100 million degrees Celsius for 20 seconds.

  • Cryptocurrency & India

    The article highlights the need for coherent cryptocurrency policy and avoid missing the benefits offered by the technology.

    Growing dominance of cryptocurrencies

    • Created by Satoshi Nakamoto in 2008, Bitcoin is the most popular cryptocurrency.
    • It is a fully decentralised, peer-to-peer electronic cash system that didn’t need the purview of any third-party financial institution.
    • The Bitcoin, which traded at just $ 0.0008 in 2010, commanded a market price of just under $65,000 this April.
    • Many newer coins were introduced since Bitcoin’s launch, and their cumulative market value touched $ 2.5 trillion this May.
    • Within a span of just over a decade, their value has surpassed the size of economies of most modern nations.
    •  The “cryptomarket” grew by over 500 per cent, even while the pandemic unleashed global economic carnage not seen since the Great Depression.
    • China’s recent crackdown on cryptocurrency had far-reaching consequences.
    • An astounding trillion US dollars were wiped out from the global cryptomarket within a span of 24 hours.
    • This kind of  volatility mentioned above has always been a concern for regulators and investors alike.

    India’s approach

    • Law enforcement and taxation agencies have called for a ban, expressing concerns over cryptocurrencies being used as instruments for illicit activities, including money laundering and terror funding.
    • In 2018, the Reserve Bank barred our financial institutions from supporting crypto transactions — but the Supreme Court overturned it in 2020.
    • Yet, Indian banks still block these transactions, and the government has circulated a draft bill outlawing all cryptocurrency activities, which has been under discussion since 2019.
    • The Reserve Bank has announced the launch of a private blockchain-supported official digital currency, similar to the digital Yuan.
    • India is increasingly mimicking China’s paradoxical attempt to centralise a decentralised ecosystem.
    • India is trying to decouple cryptocurrencies from their underlying blockchain technology, and still derive benefit.
    • Unfortunately, this is impractical, and shows a lack of understanding of this disruptive innovation.
    • The funds that have gone into the Indian blockchain start-ups are less than 0.2 per cent of the amount the sector raised globally.
    • The current central government approach makes it near-impossible for entrepreneurs and investors to acquire much economic benefit.

    Need for regulation

    • Regulation is definitely needed to prevent serious problems, to ensure that cryptocurrencies are not misused, and to protect unsuspecting investors from excessive market volatility and possible scams.
    •  However, regulation needs to be clear, transparent, coherent and animated by a vision of what it seeks to achieve.
    • India has not been able to tick these boxes, and we’re in danger of missing out in the global race altogether.

    Way forward

    • Any new regulations made in this sector should prevent the misuse of these digital assets without hindering innovation and investments.
    • Provisions have to be made to route the value extracted from these networks transparently into our financial system.
    • Regulatory uncertainties over India’s position on cryptocurrency highlights the need for clear-headed policy-making.

    Consider the question “India was a late adopter in all the previous phases of the digital revolution be it the semiconductors, the internet or smartphones. Do you think the same is happening again in India’s adoption of cryptocurrencies and blockchain technology?”

    Conclusion

    We are currently on the cusp of the next phase, which would be led by technologies like blockchain. We have the potential to channel our human capital, expertise and resources into this revolution, and emerge as one of the winners of this wave. All we need to do is to get our policymaking right.

     

  • Data is an essential weapon against Covid

    The article highlights how data played an important role in decision-making in dealing with the Covid-19 pandemic. 

    Importance of data in decision making

    • The COVID-19 pandemic has highlighted globally how important data is to governments in decision-making.
    • Epidemiological data is of paramount significance for targeting and implementing control measures for public health in a timely manner
    • Such data was used effectively in the evidence-based response and decision-making in countries like South Korea.
    • Modern response to pandemics has focused on exploiting all the available data to inform policy action in real time.

    How data analysis helped during pandemic

    • Data analysis has revealed the need for continuous and repeated tracking of case numbers, fatalities and recoveries.
    • The epidemiological concept of flattening the curve and its predictions are results of data analysis and modelling.
    • Understanding testing adequacy or lack thereof allows us to measure our preparedness, prognostic versus diagnostic ability, and shape our responses to identify, manage, and care for new cases.
    • Epidemic outbreak data like case data, medical and treatment data can be used to understand disease pathogenesis and severity.
    • Genome sequencing surveillance helps identify and track viral genome sequence variants in real time and the evolution of the virus.
    •  The concept of open access to various data enables models to improve forecast and study the spread of the disease.’

    Integration and analysis of multiple datatypes

    • The integration and analysis of multiple heterogeneous datatypes eventually would yield a holistic picture.
    • This helps guide policy decisions for control and management of public health.
    • When genome surveillance data is correlated with the magnitude of cases and their outcomes, then we can understand the transmissibility or infectivity of the virus.
    • Geographical mapping of prevalence of mutants allows us to understand viral spread and explain recoveries or deaths in a specific area.
    • The roll out of vaccinations can shape viral evolution and drug-treatment strategies.
    • Surveillance through studying genome sequencing of the virus, coupled to other epidemiological data allows us to identify these connections.

    Challenges

    • Part of the challenge lies in the standardisation of data collection, curation, annotation and the integration of data analytics pipelines for outbreak analytics.

    Way forward

    • Ensuring data availability and quality under operational constraints is critical.
    • The use of data standards instils consistency, reduces errors and enables transparency.
    • Embedded in the idea of data sharing lies the concept of data security and confidentiality.
    • Concerns of privacy and security calls for a systemic infrastructure with built-in safeguards to ensure data encryption while preserving anonymity and ensuring privacy.
    • As our dependence on data-based decisions becomes more and more critical, an urgent charter for standardised digital health data in India is required.

    Consider the question “The COVID-19 pandemic has highlighted globally how important data is to governments in decision-making. Explain how data helps in decision making and challenges in evidence-based decision making based on data.”

    Conclusion

    Rational and scientific methods necessitate data without which neither can we have information, nor knowledge or wisdom. Data sharing, and transparency and timely dissemination of data are critical to overcome the pandemic.

  • [pib] National AI Portal INDIAai

    The ‘National AI Portal (https://indiaai.gov.in)’, celebrated its first anniversary on May 28, 2021.

    National AI Portal

    • INDIAai is the National AI Portal of India – a central hub for everything AI in India and beyond.

  • Data central to effective climate action

    Article highlights the importance of data driven approach in dealing with the future disruptions and suggests the reforms in the system.

    Managing the disruption through data-driven tools

    • The data-driven tools were used for managing pandemic induced disruption.
    • This offers an opportunity to restructure the data ecosystem for managing the disruptions of the future that are more likely to be driven by climate change.

    Policies for data sharing in India

    • The National Data Sharing and Accessibility Policy (NDSAP), 2012 recognises the importance of data.
    • NDSAP recognised the importance of data in improving decision making, meeting the needs of civil society and generating revenue by permitting access to datasets.
    • In 2012, a government portal, data.gov.in was also established as a unified platform to enable sharing of data available with ministries, departments and other public agencies for wider public use.
    • The sharing of data in this platform, apart from others, is further streamlined through the nodality of Chief Data Officer-CDO in respective ministries.

    Challenges

    • Challenge remains about whether the collected data is usable, accessible and if it captures the details that end users are interested in.
    • Even after years of the portal’s operationalisation, there are multiple data-sets that aren’t updated regularly.
    • Though NITI Aayog has brought indices to track climate actions such as under SDG-13 of SDG India Index, but it remains vague in tracking improvements in climate resilience, by solely using number of lives lost due to extreme weather events.

    Reforms needed in data-ecosystem

    • 1) Complete dataset: There is a need to collect complete datasets required to assess climate risks and vulnerabilities.
    • This involves collection of datasets that are sex-disaggregated and geo-spatial and collect more nuanced dimensions like disaster response capacities.
    • Targeted research: There is a requirement of targeted research for designing better questionnaires and identifying new nodes for data collection.
    • 2) Reliability of data: The data collected has to be made reliable and usable through an accountability framework.
    • Legislation: A separate legislation in this regard would bring in the much-needed consistency in periodic collection of identified datasets and their proactive sharing in designated platforms.
    • 3) Centralisation of data: There is a need for centralising public data that currently exists with different departments and public institutions.
    • The National Data Governance Centre was planned to be set up in 2019 for precisely this objective.
    • But it is yet to be operationalised.

    Consider the question “How data driven approach could help India deal with the future disruptions that are more likely to be from climate change? Suggest the reforms needed in India’s data ecosystem.”

    Conclusion

    It is time that India places itself on track to address the issues around the known unknowns of climate change through data driven apporach.

  • [pib] 3D distribution of Molecular & Atomic Hydrogen in Galaxies

    Indian scientists have estimated the three-dimensional distribution of molecular and atomic hydrogen in a nearby galaxy which can help lead to clues to the star formation processes and the evolution of the galaxy.

    Study on Hydrogen distribution

    • Galaxies like the one we reside in, the Milky Way, consist of discs containing stars, molecular and atomic hydrogen, and helium.
    • The molecular hydrogen gas collapses on itself in distinct pockets, forming stars, its temperature was found to be low –close to 10 kelvin, or -263 ºC, and thickness is about 60 to 240 light-years.
    • The atomic hydrogen extends both above and below the discs.
    • Indian scientists have estimated that molecular hydrogen extends farther from the disc in both directions, up to about 3000 light-years.
    • This gaseous component is warmer than the one straddling the disc and has comparatively lesser densities, thus escaping earlier observations.
    • They called it the ‘diffuse’ component of the molecular disc.

    Answer this PYQ in the comment box:

    Q. Which one of the following sets of elements was primarily responsible for the origin of life on the Earth?

    (a) Hydrogen, Oxygen, Sodium

    (b) Carbon, Hydrogen, Nitrogen

    (c) Oxygen, Calcium, Phosphorous

    (d) Carbon, Hydrogen, Potassium

    Why does this study matter?

    • The molecular hydrogen gas converts to individual stars under the pull of gravity, thus holding clues to the star formation processes and the evolution of the galaxy.
    • If a significant part of the gas extends beyond the thin disc of a few hundred light-years, it may explain why astronomers also observe stars at a few thousand light-years perpendicular to the galactic disc.

  • Indian SARS-CoV-2 Genomic Consortia (INSACOG)

    In early March, members of the Indian SARS-CoV-2 Genomic Consortia (INSACOG), an advisory group to the Central government, warned of a new and contagious form of the novel coronavirus.

    What is INSACOG?

    • INSACOG is a consortium of 10 labs across the country tasked with scanning COVID-19 samples from swathes of patients and flagging the presence of variants that were known to have spiked transmission internationally.
    • It has also been tasked with checking whether certain combinations of mutations were becoming more widespread in India.
    • Some of these labs had begun scanning for mutations in April 2020 itself, but it was not a pan-India effort.
    • The institutes involved were laboratories of the Department of Biotechnology, the CSIR, the ICMR, and the Ministry of Health & Family Welfare (MoHFW).
    • The National Centre for Disease Control (NCDC) under the MoHFW was tasked with coordinating the collection of samples from the States as well correlating disease with the mutations.
    • The work began in January by sequencing samples of people who had a history of travel from the United Kingdom and a proportion of positive samples in the community.

    What are the findings?

    • The “foreign” variants identified were primarily the B.1.1.7 (first identified in the United Kingdom) and the B.1.351 (first found in South Africa) and a small number of P2 variants (from Brazil).
    • However, some labs flagged the growing presence of variants identified in India that were clubbed into a family of inter-related variants called B.1.617, also known as the ‘double mutant’ variant.
    • It was primarily due to two mutations — E484Q and L452R — on the spike protein.
    • The B.1.617 family was marked as an international ‘variant of concern’ after it was linked to a recent spike in cases in the UK.
    • INSACOG labs also found that the B.1.1.7 variant, which is marked by increased infectivity, is distinctly more prevalent in several northern and central Indian States in comparison to southern States.

    Beyond identifying patterns, why is genome sequencing useful?

    • The purpose of genome sequencing is to understand the role of certain mutations in increasing the virus’s infectivity.
    • Some mutations have also been linked to immune escape, or the virus’s ability to evade antibodies, and this has consequences for vaccines.
    • Labs across the world, including many in India, have been studying if the vaccines developed so far are effective against such mutant strains of the virus.
    • They do this by extracting the virus from COVID-19-positive samples and growing enough of it. Then, blood serum from people who are vaccinated, and thereby have antibodies, is drawn.
    • Using different probes, scientists determine how much of the antibodies thus extracted are required to kill a portion of the cultured virus.
    • In general, the antibodies generated after vaccination — and this was true of Covaxin, Covishield, Pfizer and Moderna jabs — were able to neutralize variants.
    • Antibody levels are not the only markers of protection and there is a parallel network of cellular immunity that plays a critical role in how vaccines activate immunity.
    • The current evidence for most COVID-19 vaccines is that they have almost 75% to 90% efficacy in protecting against disease but less so in preventing re-infection and transmission.

    Challenges faced by INSACOG

    • Given that the novel coronavirus is spreading, mutating, and showing geographical variations, the aim of the group was to sequence at least 5% of the samples.
    • For many reasons, this has so far been only around 1%, primarily due to a shortage of funds and insufficient reagents and tools necessary to scale up the process.
    • While some of these issues, the INSACOG, in spite of being peopled by expert scientists, is ultimately an advisory group to the Central government and part of its communication structure.
    • Warnings about emerging variants were not made public with sufficient urgency and the sharing of datasets, even within constituent groups of the INSACOG, was less than ideal.

  • Medicine from the Sky Project

    The Telangana government has selected 16 primary healthcare centres (PHCs) spread around Vikarabad area hospital for pilot testing the ambitious ‘Medicine from the sky’, the first-of-its-kind project involving delivery of medicines through multiple drones.

    Medicine from the Sky Project

    • A consortium of seven operators headed by Blue Dart Med-Express had been selected for the project to be launched in the VLOS range of 500 metres initially and will be scaled up gradually to a 9 km range.
    • The selected PHCs are both within the Visual Line of Sight (VLOS) and Beyond Visual Line of Sight (BVLOS) range.
    • The project would be launched in three waves starting with a pilot followed by mapping the route network for the operation of drones for delivering vaccine/medicine in the desired community health centres and PHCs.
    • The project is being launched following the approval granted by the Civil Aviation Ministry to the request made by the State to grant conditional exemption from the Unmanned Aircraft System Rules 2021.

    Benefits of the project

    • The project is aimed at assessing alternative logistics route in providing safe, accurate and reliable pickup and delivery of health care items like medicines, vaccines, units of blood and other lifesaving equipment from the distribution centre to a specific location and back.
    • The model, once successful, would enable deliveries from district medical stores and blood banks to PHCs, CHCs and further from PHCs/CHCs to central diagnostic laboratories.

    Back2Basics: What is VLOS (Visual Line of Sight)?

    • Visual Line of Sight (‘VLOS’) operations are a type of operation in which the remote pilot maintains continuous, unaided visual contact with the unmanned aircraft. In its simplest term, the aircraft must always be visible to the pilot.
    • This allows the remote pilot to control the flight path of the unmanned aircraft in relation to other aircraft, people, and obstacles for the purpose of avoiding collisions.
    • Extended Visual Line of Sight operations (‘EVLOS’) allows flight Beyond Visual Line of Sight of the Remote Pilot by using ‘trained observers’.
    • Trained observers are used to comply with the separation and collision avoidance responsibilities of the operator.
    • ‘Beyond Visual Line of Sight’ operations is where the flying of a drone is without  a pilot maintaining a visual line of sight on the aircraft at all times.
    • Instead, the pilot operates the UAV using Remote Pilot Station (RPS) / Ground Control Station (GCS) instruments.

  • Tianwen-1 lands successfully on Mars

    China landed a spacecraft on Mars carrying its first Mars rover in a big boost to its space ambitions.

    UPSC may ask an MCQ asking: Which of the following is/are the space missions related to Mars? It may throw up 4-5 options (which we all get confused at after few months) like Cassini , InSight , Messanger, Voyager etc.

    Tianwen-1 Mission

    • The mission is named after the ancient Chinese poem ‘Questions to Heaven’, the Tianwen-1.
    • It is an all-in-one orbiter; lander and rover will search the Martian surface for water, ice, investigate soil characteristics, and study the atmosphere, among completing other objectives.
    • It will be the first to place ground-penetrating radar on the Martian surface, which will be able to study local geology, as well as rock, ice, and dirt distribution.
    • The lander descended successfully onto the surface of the red planet carrying a rover named Zhurong, named after a god of fire for a planet known in Chinese as the planet of fire.
    • Only the Soviet Union and the United States had previously carried out a successful landing on Mars.

    Back2Basics: Various missions on Mars

    • The USSR in 1971 became the first country to carry out a Mars landing– its ‘Mars 3’ lander being able to transmit data for 20 seconds from the Martian surface before failing.
    • The country made it’s second and Mars landing two years later in 1973.
    • The second country to reach Mars’s surface, the US, holds the record for the most number of Mars landings.
    • Since 1976, it has achieved 8 successful Mars landings, the latest being the ‘InSight’ in 2019 (launched in 2018).
    • India and the European Space Agency have been able to place their spacecraft in Mars’s orbit.
    • India’s Mars Orbiter Mission (MOM) or ‘Mangalyaan’ was able to do so in September 2014, almost a year after its launch from the Satish Dhawan Space Centre in Andhra Pradesh.
    • The Chinese mission now is expected to take off around the same time when NASA is launching its own Mars mission– the ambitious ‘Perseverance’ which aims to collect Martian samples and bring them back.

  • Mucormycosis infection in COVID-19 patients

    Hospitals across the country have started to report a number of cases of Mucormycosis, an invasive fungal infection affecting patients who have recently recovered from COVID-19.

    What is Mucormycosis?

    • Mucormycosis is an aggressive and invasive fungal infection caused by a group of moulds called micromycetes.
    • It can affect various organs but is currently manifesting as invasive rhino-orbito-cerebral disease, crawling through the sinus and working its way to the brain, affecting the ear, nose, throat, and mouth.
    • While it is not contagious, it can cause a lot of damage internally and can be fatal if not detected early.
    • It is an old disease; perhaps new and concerning is the sudden increase in the invasive form of the sinus variant, which involves the orbit, and at times the brain, leading to blindness, stroke or death.

    What causes the disease?

    • Diabetes mellitus is the most common underlying cause, followed by haematological malignancies and solid-organ transplants.
    • Diabetes mellitus was reported in 54% to 76% of cases, according to a report.
    • What seems to be triggering Mucormycosis in patients post COVID-19 is indiscriminate use of a high dose of steroids in COVID-19 patients, sometimes even in minimally symptomatic patients.
    • This leads to spikes in the sugar level among diabetics, which, in turn, renders them vulnerable.

    Symptoms

    • The symptoms to watch out for are a stuffy nose, bloody, blackish, or brown discharge from the nose etc.
    • Other symptoms include blackish discolouration of the skin, swelling or numbness around the cheek, one-sided facial pain, toothache or jaw pain, drooping of the eyelids or eyelid swelling, double vision, redness of eyes, and sudden decrease in vision.

    Treatment

    • The mainline of treatment is an anti-fungal drug called amphotericin B, which is given over an extended period of time under the strict observation of a physician.
    • Rational use of steroids is necessary, and constant monitoring of sugar levels and resorting to insulin use to control these levels if required is essential.
    • Surgery to remove the fungus growth might also be warranted.

    Preventive measures

    • It is important to keep blood sugar levels under control and ensure that appropriate calibration of oral drugs or insulin is done from time to time.
    • Further, recognising the symptoms and seeking treatment early if there are two or three symptoms at a time is key.
    • Like most illnesses, if detected early, Mucormycosis can be cured.
