  • How Web3 differs from Web2?

    web

    Central idea: The article discusses the key features of Web3, including its decentralized nature, peer-to-peer transactions, and greater control over data and digital assets for users.

    What is Web3?

    • Web3, also known as Web 3.0, is the next generation of the World Wide Web that emphasizes decentralization, security, and user privacy.
    • It is essentially a vision of the internet where users have more control over their data, identities, and online interactions.
    • It is built on blockchain technology, which enables peer-to-peer transactions without the need for intermediaries such as banks, governments, or other third parties.
    • This decentralized approach to the web allows for greater transparency and trust, as well as more secure and private transactions.
    • Web3 technologies include blockchain platforms like Ethereum, IPFS (InterPlanetary File System) for distributed file storage, decentralized identity systems like uPort, and decentralized marketplaces like OpenBazaar.

  • Repeating radio signal detected from nearby Exoplanet YZ Ceti b

    ceti

    Central idea: Astronomers have detected a repeating radio signal from the YZ Ceti exoplanet that suggests the presence of a magnetic field around it.

    What is YZ Ceti b?

    • YZ Ceti b is an earth-sized exoplanet (a planet that orbits a star other than our sun).
    • It is located barely 12 light-years from Earth, and it rotates around a small red dwarf star called YZ Ceti.

    How was the discovery made?

    • The researchers had to make multiple rounds of observations before they could detect the radio signals from the star YZ Ceti, which seemed to match the orbital period of the planet YZ Ceti b.
    • From this, they deduced that the signals were a result of the interaction between the planet’s magnetic field and the star.

    Why does the magnetic field matter?

    • Intense bursts of energy from the YZ Ceti star-exoplanet exchange produce spectacular auroral lights, similar to the energy surges from the sun that disrupt telecommunications on earth.
    • The radio waves confirmed the existence of an exoplanetary magnetic field.
    • This can only be produced if the exoplanet orbits very close to its parent star and has its own magnetic field to influence the stellar wind and generate the signals.

    What’s the implication for YZ Ceti b?

    • The small orbit of YZ Ceti b indicates that the planet takes just a couple of earth days to circle its star.
    • Nearly half of all the stars visible in the sky could potentially harbor rocky, earth-sized planets in habitable orbits around them.
    • Astronomers indicated that the possibility of the existence of a magnetic field on the Earth-like exoplanet, called YZ Ceti b, probably hints at the habitability of life on that planet.

    How common are such magnetic fields?

    • Planetary scientists have never been able to identify magnetic fields on smaller, rocky exoplanets until now.
    • The survival of a planet’s atmosphere may depend on its having, or not having, a strong magnetic field, since the field protects its atmosphere from being eroded by the charged particles blowing in from its star.

  • What are Stablecoins?

    stablecoins

    The US Congress (Parliament) has made another attempt to create a legislative framework for the increasingly popular stablecoins, a sort of cryptocurrency that is pegged to a particular commodity or currency.

    What are Stablecoins?

    • Stablecoins are cryptocurrencies designed to maintain a stable value, typically by being pegged to a stable asset such as the US dollar.
    • Investing in stablecoins can help mitigate market volatility because they are less susceptible to price fluctuations than other cryptocurrencies such as Bitcoin or Ethereum or any other.

    Types of stablecoins

    Fiat-backed stablecoins Backed by reserves of fiat currency held in a bank account or other secure location. Example: Tether (USDT)
    Commodity-backed stablecoins Backed by reserves of a physical commodity, such as gold or silver. Example: PAX Gold (PAXG)
    Algorithmic stablecoins Use algorithms or smart contracts to maintain a stable value. Example: Dai stablecoin (DAI)

     

    How can Stablecoin mitigate market volatility?

    Explanation
    Hedging against volatility
    • Help investors hedge against volatility and reduce their risk exposure.
    • Pegged to a stable asset, which can provide a haven during market turbulence.
    • If the value of Bitcoin or Ethereum drops suddenly, investors can move their funds into stablecoins to protect their portfolio from further losses.
    Greater flexibility in transferring funds
    • Greater flexibility and convenience compared to traditional fiat currencies.
    • Quickly and easily transferred between wallets and exchanges, making them ideal for cross-border transactions.
    • Investors take advantage of investment opportunities in other markets and avoid currency exchange fees and delays.
    Arbitrage trading
    • Used for arbitrage trading, which involves buying an asset in one market and selling it in another market for a higher price.
    • As stablecoins are pegged to a stable asset, investors can quickly move funds between exchanges without worrying about price fluctuations, making arbitrage trading easier and potentially more profitable.

     

    What are the risks?

    Explanation
    Stability of the asset
    • Stablecoins are reliant on the stability of the asset they are pegged to.
    • If the value of that asset drops, it can lead to a drop in the stablecoin’s value as well.
    • This could result in losses for investors who hold the stablecoin.
    Transparency and regulation
    • There are concerns over the transparency and regulation of stablecoin issuers.
    • This could result in a loss of trust in the stablecoin and a subsequent drop in its value.
    • There is no proper regulation and oversight.
    • There is a risk that stablecoin issuers may engage in fraudulent or unethical behaviour, which could lead to losses for investors.
    • It is important for investors to carefully assess the reputation and credibility of the stablecoin issuer before investing in a stablecoin.

    What are EMIC Waves?

    • Electromagnetic Ion Cyclotron (EMIC) waves are a type of plasma wave that occurs in the Earth’s magnetosphere.
    • They are caused by the interaction of energetic particles in the radiation belts with the Earth’s magnetic field.
    • These waves have frequencies in the range of a few hundred hertz to a few kilohertz and are known to play an important role in the acceleration and loss of energetic particles in the Earth’s magnetosphere.
    • The study of EMIC waves is important for understanding the effects of space weather on satellite communication and navigation systems.

    Identification and study of EMIC waves

    • A team of scientists from the Indian Institute of Geomagnetism (IIG) analysed data collected between 2011 and 2017 by the Induction Coil Magnetometer.
    • The device was installed at the Indian Antarctic station Maitri to bring out several aspects of the ground observation of the EMIC waves.

    Significance of the study

    • This study is important to improve our understanding of EMIC wave modulation and how they interact with energetic particles that impact satellites and their communication.
    • It could help understand the impact of energetic particles in the radiation belts on low orbiting satellites and lead to improved satellite communication systems.

    Back2Basics:  Indian Antarctic Programme

    • It is a scientific program run by the National Centre for Antarctic and Ocean Research under the Ministry of Earth Sciences.
    • It was launched in 1981 and since then India has been operating research stations in Antarctica.
    • It gained global acceptance with India’s signing of the Antarctic Treaty and subsequent construction of the Dakshin Gangotri Antarctic research base in 1983, superseded by the Maitri base from 1989.
    • The program conducts research in areas such as geology, oceanography, atmospheric sciences, and earth sciences.
    • India currently operates two permanent research stations in Antarctica – Maitri and Bharati.
    • The program also has plans to set up a third research station called ‘Siddhanta’ in the coming years.
    • Apart from conducting research, the program also engages in logistics support, environmental monitoring, and outreach activities.

  • What is Civil Union, how is it different from Marriage?

    Central idea

    • The Indian judiciary is currently hearing arguments about the legal recognition of same-sex unions under the Special Marriage Act.
    • The Centre has contested the maintainability of the petitions, and the judiciary’s right to confer legal recognition on the “socio-legal institution” of marriage.
    • However, the CJI has clarified that the scope of the hearing would be limited to developing a notion of a Civil Union that finds legal recognition under the Act.
    • This article explains what civil unions are, how they differ from marriage, and which countries allow them.

    What is a Civil Union?

    • A civil union is a legal status that allows same-sex couples specific rights and responsibilities normally conferred upon married couples.
    • Civil unions resemble marriages and bring with them employment, inheritance, property, and parental rights, among other things.

    How is a civil union different from marriage?

    • In the US, prior to the Supreme Court’s landmark ruling in “Obergefell v. Hodges” in 2015, a majority of the states had civil union laws that allowed same-sex couples to marry without providing them formal recognition of the same.
    • Civil unions were recognised solely by issuing states and not by federal law, which meant that such couples could not enjoy the benefits of being in a civil union uniformly across all states.
    • After the legalisation of same-sex marriages, several civil unions were converted into marriages.

    What other countries allow civil unions?

    • Several countries allow civil unions.
    • Before Sweden legalised same-sex marriages in 2009, LGBTQ couples there could apply for civil unions and enjoy benefits such as the right to adopt.
    • In Norway, couples could enter into civil unions from 1993, which gave way to a new law 15 years later allowing such couples to marry, adopt, and undergo state-sponsored artificial insemination.
    • In Austria, same-sex couples could form civil partnerships between 2010-2017 until a court ruling deemed civil unions discriminatory, and such marriages were legalised.
    • Similarly, countries like Brazil, Uruguay, Andorra, and Chile recognised the right of same-sex couples to enter into civil unions even before they formally recognised their legal right to marriage.

  • Plant ‘cries’: Recalling Jagadish Chandra Bose

    bose

    Central idea

    • A recent discovery by researchers from Tel Aviv University in Israel, that plants make distinct sounds in the ultrasonic range when faced with stress, made headlines around the world.
    • However, Indians who had grown up hearing about Jagadish Chandra Bose’s work, more than a century ago, on plant physiology and their ability to feel pleasure and pain, were not surprised.

     

    Details
    Who was JC Bose? – Born in 1858 in Mymensingh, Bengal.

    – A polymath who made significant contributions to physics, biophysics, and plant physiology

    – Graduated from Calcutta University with honors in physics and studied in London and Cambridge.
    Notable works – Developed sensitive instruments for wireless telegraphy and demonstrated the first-ever wireless transmission of microwaves in 1895.

    – Showed that plants produce electrical signals in response to stimuli and made significant contributions to biophysics.
    Recognition & Controversy – Despite his contributions, he was not awarded a Nobel Prize, which many believe he deserved.

    – Refused to obtain patents for his work and rejected the idea of making money from science.

    – Claimed that even inanimate inorganic matter could respond to stimulus and regarded plants as intermediates in a continuum between animals and non-living materials, which was not easily accepted by his contemporaries.
    Legacy and Significance – Founded the Bose Institute, a premier research institute in India.

    – The crater Bose on the Moon is named after him.

    – Regarded as one of India’s greatest scientists, and his legacy continues to inspire future generations of scientists.
    Significance – Bose’s work on plant physiology and biophysics was ahead of his time and not fully understood by his contemporaries.

    – However, over the years, much of his work has been confirmed.

  • What is the Consumer Confidence Index (CCI)?

    confidence

    Central idea

    • The Consumer Confidence Survey was conducted in the first half of March 2023 across 19 cities.
    • This article analyses the survey results, released this month, and breaks down the findings under different sections.

    What is Consumer Confidence Survey?

    • The Reserve Bank of India (RBI) conducts a Consumer Confidence Survey to measure consumers’ perceptions of the prevailing economic situation.
    • The survey is conducted across various cities and measures consumer confidence on parameters such as the economy, employment, price, income, and spending.
    • The survey consists of questions regarding consumers’ sentiments over various factors in the current situation and future.

    Here are a few parameters that help aggregate overall confidence:

    1. Spending: The consumer is asked about the willingness to spend on major consumer durables, purchasing vehicles, or real estate. This measures the overall spending scenario on necessities as well as luxuries for the next quarter.
    2. Employment: The consumer is asked about current and future ideas on employment situations, joblessness, job security, which reflects the sentiments of the current or expected employment in the country.
    3. Inflation: The consumer is asked about interest rates and levels of prices of all goods, tracking the price expected by consumers and their spending on basic necessities.

    About the Consumer Confidence Index (CCI)

    • CCI is a survey that is conducted every two months to measure how optimistic or pessimistic the consumers are regarding their financial situation.
    • The index measures the change in consumer perception on the financial situation in the last year and the future expectations index measures what the consumer thinks about his financial situation in the coming one year.
    • The main variables of the survey are: Economic situation, Employment, Price Level, Income and Spending.

    Current perceptions of the survey

    • The survey estimates current perceptions and a year-ahead expectations on the economy, employment, price, income, and spending.
    • The results show that consumer confidence continues to recover from its historic low of mid-2021, but still remains pessimistic at 87.0, a 2.2 point increase from previous results.
    • The assessment of inflation conditions improved for the current period reflecting a higher confidence in prevailing economic conditions.
    • With regards to spending, sentiments were positive with signs of improvement compared to the last round conducted in January 2023.

    What does this imply?

    • The survey shows that while consumer confidence is slowly recovering, it still remains pessimistic.
    • The survey results indicate positive sentiments on employment and spending, but a marginal dip in the country’s future economic situation.
    • Credit growth numbers indicate a rise in consumer spending.
    • The upcoming state and general elections could have an impact on the economy, and it remains to be seen how it will play out.

    • Table 3 shows the share of the top exporting commodity of the top exporting district in India’s total exports.
    • For instance, Jamnagar’s petroleum products export formed 67% of India’s total exports for that commodity, while Surat’s precious stones and jewellery exports formed 36% of India’s total exports for that commodity.

     

  • What is Ninth Schedule of the Constitution?

    Central idea: Chhattisgarh CM has written to the Prime Minister seeking the inclusion of two amendment Bills allowing for higher quotas in jobs and educational institutions in the Ninth Schedule of the Constitution.

    What is Ninth Schedule?

    • The Ninth Schedule is a legal provision in the Constitution of India that provides immunity to certain laws from judicial review.
    • It is a list of Central and State laws that are immune from judicial review.
    • These laws are not subject to judicial scrutiny or challenge in any court of law, including the Supreme Court of India.
    Details
    Definition A list of Central and State laws that are immune from judicial review.
    History Added to the Constitution by the First Amendment in 1951.
    Purpose back then To protect land reforms and other progressive laws from being challenged in courts.
    Significance Used to protect laws related to land reforms, reservation in education and employment, anti-defection laws, and other progressive measures aimed at social justice and equality.
    Criticisms Criticised for shielding unconstitutional laws and violating fundamental rights.

    Supreme Court of India has struck down several laws in the Ninth Schedule on the grounds that they violate the basic structure of the Constitution.
    Amendment Constitution (Ninety-Sixth Amendment) Act, 2001 added a provision stating that any law added to the Ninth Schedule after April 24, 1973, can be challenged in courts on the ground that it violates the fundamental rights guaranteed by the Constitution.

     

    What is the request made by CG CM?

    • In Chhattisgarh’s case, the two amendment Bills were passed unanimously by the State Assembly paving the way for 76% quota for Scheduled Caste, Scheduled Tribes and Other Backward Classes.
    • However, the Bills are yet to receive the Governor’s nod.
    • The Chhattisgarh High Court had struck down a 2013 State government order to allow 58% quota, holding that reservation above the 50% ceiling was “unconstitutional.”

    Request for Inclusion in Ninth Schedule

    • The CM presented the demographics of the State and wrote that the socio-economic and educational condition of the OBC people of the State is as weak as that of the SC/ST people.
    • He argued that the inclusion of the amended provision in the Ninth Schedule of the Constitution is necessary for the people of the deprived and backward classes to get justice.
