  • What makes mosquitoes suck blood?

    Why in the News?

    A study published in the Proceedings of the National Academy of Sciences (PNAS) 1 has suggested that a pair of hormones work together to activate or suppress mosquitoes’ blood cravings.

    Mosquito Species and Behavior

    • There are around 3500 mosquito species globally, found on every continent except Antarctica.
    • Female mosquitoes consume blood to aid in egg development.
    • After feeding, female mosquitoes lose their appetite for blood until they lay their eggs.

    Research by Michael Strand and Team

    • Strand observed that levels of the mosquito gut hormone F (NPF) spiked when mosquitoes were seeking a host and dropped after feeding.
    • Their study analyzed mosquito enteroendocrine cells responsible for gut hormone production.
    • Hormonal Mechanisms:
      • NPF levels increased before blood meals and decreased six hours after feeding.
      • Another gut hormone, RYamide, was found to influence mosquitoes’ blood lust. As NPF levels decreased after a blood meal, RYamide levels increased, and vice versa.
      • The researchers concluded that NPF and RYamide work together to regulate mosquitoes’ attraction to humans and other hosts.

    Implications of the Study

    • Controlling the Deadliest Animal: Mosquitoes are the deadliest animal on the planet, acting as vectors for diseases such as malaria, dengue, West Nile virus, yellow fever, Zika, chikungunya, and lymphatic filariasis, which collectively kill more people than any other creature.
    • Pesticide Development: The discovery could lead to new pesticide targets for preventing mosquito reproduction and disease transmission.

    Note: Mosquitoes are responsible for over 1 million human deaths per year worldwide. They transmit deadly diseases like malaria, yellow fever, dengue, and Zika virus

    PYQ:

    [2023] ‘Wolbachia method’ is sometimes talked about with reference to which one of the following?

    (a) Controlling the viral diseases spread by mosquitoes
    (b) Converting crop residues into packing material
    (c) Producing biodegradable plastics
    (d) Producing biochar from thermo-chemical conversion of biomass

  • Universe had Spiral Galaxies 4 billion years sooner than expected: Study

    Why in the News?

    A new study has revealed more spiral galaxies in the universe’s youth than astronomers had previously expected.

    Universe’s Age and Galaxy Types

    • The universe is about 13.8 billion years old and hosts various kinds of galaxies, from spiral to elliptical.
    • Astronomers believed spiral galaxies formed about 6 billion years ago, but the new study calls this into question.
    • Younger galaxies tend to spiral, while older ones have a variety of shapes, making the study of older galaxies more challenging due to fainter light.

    Back2Basics: Spiral Galaxy

    • Spiral galaxies are a type of galaxy characterized by their spiral structure.
    • They are among the most common types of galaxies in the universe.
    • Our own Milky Way is a classic example of a spiral galaxy.

    Key Characteristics:

    • Central Bulge: A dense, spherical structure at the centre composed mainly of older stars.
    • Disk: Surrounding the bulge is a flat, rotating disk of stars, gas, and dust. The disk contains younger stars and spiral arms.
    • Spiral Arms: These are the defining features, winding outward from the central bulge. The arms are sites of active star formation and appear brighter due to the presence of young, hot stars.
    • Halo: A roughly spherical region surrounding the disk, containing old stars and globular clusters.

    Formation and Evolution:

    • Spiral galaxies are thought to form from the gravitational collapse of gas and dust in the early universe.
    • They maintain their structure through the rotation of the disk and the gravitational influence of the central bulge and halo.
    • Interactions and mergers with other galaxies can distort or destroy their spiral structure, potentially transforming them into elliptical galaxies.

    Formation of Galaxies

    • As the universe cooled from a dense plasma state, hot gas formed clumps that became galaxies.
    • These early galaxies had irregular shapes and lacked disks.
    • Spiral Formation Theory:
      • The traditional theory suggested that it took billions of years for hot, thick disks to become thinner and form spiral arms.
      • The new study suggests that cooling and spiral formation occur around the same cosmic time.

    How is this verified?

    • Astronomers observe star formation in real time but study galaxy evolution through “astronomical archaeology.”
      • Understanding the fraction of spiral galaxies helps astronomers trace the biography of galaxies.
      • Infrared and optical wavelengths are used to detect early galaxies, requiring powerful telescopes due to the faint light of older galaxies.
    • Study Methodology:
      • The University of Missouri team used the JWST to study 873 galaxies and identified at least 216 spiral galaxies, some dating to 1.5 billion years after the universe’s birth.
      • Each of the six authors classified the images as spiral or non-spiral, ensuring the result is free of human bias.

    Findings and Implications

    • The fraction of spiral galaxies increased from about 8% to 48% between 3 billion and 7 billion years after the Big Bang, higher than previously observed.
    • The study challenges existing models and suggests that galaxy formation theories need to be more complex.

    PYQ:

    [2022] Launched on 25th December, 2021, James Webb Space Telescope has been much in the news since then. What are its unique features which make it superior to its predecessor Space Telescopes? What are the key goals of this mission? What potential benefits does it hold for the human race?

    About Great Indian Bustards

    • GIBs are the largest among the four bustard species found in India, the other three being MacQueen’s bustard, the lesser florican, and the Bengal florican.
    • GIBs’ historic range included much of the Indian sub-continent but it has now shrunken to just 10 percent of it.
      • Among the heaviest birds with flight, GIBs prefer grasslands as their habitats.
    • GIBs are mainly found in Desert National Park, Rajasthan.
    • Bustards face major threats, including habitat changes and collisions with power lines.
    • Protection accorded:
      • Birdlife International: uplisted from Endangered to Critically Endangered (2011)
      • Protection under CITES: Appendix I
      • IUCN status: Critically Endangered
      • Protection under Wildlife (Protection) Act: Schedule I

    What is the GIB Recovery Plan?

    • The proposal was prepared by the Wildlife Institute of India (WII).
    • The proposal includes:
      • Rewilding Bustards bred in ex-situ conservation centres,
      • Conducting detailed population studies, and
      • Developing artificial insemination techniques.

    Back2Basics: Wildlife Institute of India (WII)

    • WII is an autonomous institution under the Ministry of Environment, Forest and Climate Change.
    • It was established in 1982.
    • It is based in Dehradun, Uttarakhand.
      • Functions: It offers training programs, academic courses, and advisory in wildlife research and management.

    Why such a move?

    • Indicator Species: The GIB is a key indicator species of grassland habitat, signalling the health of these environments.
    • Population Decline: The population has declined from around 700 individuals to less than 150 due to habitat loss, predation, and death by overhead power lines.
    • Supreme Court Order: The Supreme Court recognized the threat from power lines and constituted an expert committee to assess the feasibility of overhead and underground electric lines in the bustard’s habitats.

    Conservation Efforts and Achievements

    • Recovery Plan: Initial efforts began between 2012-2013 with a long-term recovery project, which firmed up in 2016 with a Rs 33.85 crore funding outlay.
    • Funding and Agreements: The project was funded by the Compensatory Afforestation Fund, with a tripartite agreement in 2018 involving the Environment Ministry, Rajasthan Forest Department, and WII.
    • In-Situ Breeding: Conservation breeding began in 2019, resulting in a founder population of 40 GIBs at the Ramdevra centre.

    Achievements at Breeding Centres

    • Successful Breeding: Eggs collected from the wild were incubated and chicks were hand-reared. The breeding centres now have a founder population of 40 GIBs.
    • Scientific Reasoning: Creating a founder population prevents extirpation and captures genetic variability. The goal is to have at least 20 adult birds including 15 females.

    Future Plans

    • Next Phase (2024-2033): The immediate next phase will run until 2029, targeting the upgradation of the CBC at Ramdevra and the development of the Lesser Florican CBC at Sorsan.
    • Population Surveys: Surveys will be conducted in Rajasthan and other range states to monitor population status.

  • How urban expansion makes Delhi susceptible to flooding? 

    Why in the news?

    Heavy rain brought Delhi and NCR to a standstill, causing severe water-logging, traffic snarls, power cuts, property damage, and 11 deaths from structural collapses and electrocution.

    • Climate change and rising temperatures have intensified the overflow of rivers and lakes, snowmelt, storm surges (such as hurricanes and cyclones), and abnormally heavy rains. This, coupled with locational vulnerabilities, has resulted in increased instances of urban flooding.

    Principal Reasons Behind Chronic Urban Flooding in Delhi

    • Unchecked Urban Expansion: Rapid, ill-planned urban growth without considering natural topography and drainage patterns.
    • Inadequate Drainage Systems: Existing drainage systems are unable to handle high-intensity rainfall, leading to significant runoff.
    • Concrete Overdevelopment: Excessive construction on low-lying areas and flood plains, leaving little room for water absorption.
    • Destruction of Water Bodies: Reduction of water bodies that could manage floodwaters, with many converted into real estate.
    • Neglect of Water in Urban Planning: Lack of a comprehensive water masterplan that integrates water management into urban development.

    Present Scenario of Rapid Urbanization in Delhi NCR

    • Fastest Urban Expansion: Delhi is one of the fastest-growing cities globally, with its geographic size almost doubling between 1991 and 2011.
    • Population Growth: Predicted to overtake Tokyo as the world’s most populous city by 2030, with an estimated population of 39 million.
    • Urban Sprawl: Expansion primarily on the peripheries, converting rural areas into urban zones, and rapid urbanization in NCR cities like Ghaziabad, Faridabad, Noida, and Gurugram.

    Challenges and Limitations

    • Topographical Neglect: Building in low-lying areas and on flood plains, disrupting natural drainage and increasing flood risks.
    • Inadequate Infrastructure: Insufficient desilting of drains, inadequate stormwater management systems, and improper solid waste management.
    • Lack of a Water Masterplan: Absence of comprehensive planning for clean and wastewater flows, leading to issues like the flooding of new infrastructures like the Pragati Maidan Tunnel.
    • Reduction of green space and water bodies: Conversion of green spaces and water bodies into concrete developments, further aggravating flood situations.
    • Inconsistent Urban Planning: No systematic approach to integrating natural water flows and gradients into urban development plans.

    Recommendations (Way Forward)

    • Integrated Urban Planning: Develop a water masterplan that prioritizes water management in urban development.
    • Protection of Water Bodies: Preserve and restore existing water bodies to manage floodwaters effectively.
    • Sustainable Development: Implement policies to prevent construction in low-lying and flood-prone areas.
    • Infrastructure Improvement: Enhance drainage systems, desilting processes, and solid waste management to reduce water logging.
    • Public Awareness: Increase awareness about the importance of sustainable urban planning and the risks of unchecked urbanization.
    Case study: Copenhagen, Denmark has an excellent “Five Finger Plan” that integrates urban infrastructure, transport, and green spaces. The city emphasizes sustainability, public life, and sensitive development. Indian Government can consider this plane.

  • Digital jurisprudence in India, in an AI era  

    Why in the news?

    Generative AI’s transformative potential challenges existing legal frameworks and judicial precedents, which are inadequate for effectively governing this rapidly-evolving technology designed for a pre-AI world.

    What is Generative AI?

    • Generative AI refers to artificial intelligence models that can generate original content like text, images, videos, and audio in response to prompts or requests.
    • These models learn patterns from large datasets and use that knowledge to create new content that resembles the training data.

    Persistent and Contentious Issues in Internet Governance

    Safe Harbour and Liability Fixation:

    • The Shreya Singhal judgment upholds Section 79 of the IT Act, granting intermediaries ‘safe harbour’ protection against liability for hosted content, contingent upon meeting due diligence requirements.
    • Challenges arise in applying these provisions to GAI tools, with debates on whether they should be classified as intermediaries, conduits, or active creators.
    • The Delhi High Court’s ruling in the Christian Louboutin Sas vs Nakul Bajaj and Ors (2018) case limited safe harbour protection to “passive” intermediaries.
    • The classification of GAI tools complicates the assignment of liability, especially in cases of user reposts.

    Generative AI and Legal Conflicts:

    • GAI outputs have led to legal conflicts, such as a lawsuit in the U.S. against OpenAI for defamation by ChatGPT.
    • Ambiguities in classifying GAI tools complicate legal decisions regarding liability.

    What Does the Indian Copyright Act 1957 Say?

    • Section 16 specifies that copyright protection is granted only under the provisions of the Act, with reluctance globally to extend protection to AI-generated works.
    • Critical questions include whether existing copyright laws should be revised for AI, the need for co-authorship with humans, and the responsibility for copyright infringement by AI tools.
    • The 161st Parliamentary Standing Committee Report highlights the inadequacy of the Copyright Act to facilitate AI authorship and ownership.
    • Current Indian law allows copyright owners to take legal action against infringement, but liability for AI-generated content remains unclear.

    Steps to Pursue (Way forward)

    • Learning by Doing: Implement a sandbox approach, granting temporary immunity from liability to GAI platforms for responsible development and data gathering to inform future regulations.
    • Data Rights and Responsibilities: Overhaul the data acquisition process for GAI training, ensuring legal compliance, proper licensing, and compensation for intellectual property used in training models. Potential solutions include revenue-sharing or licensing agreements with data owners.
    • Simplify the Licensing: Licensing data for GAI is complex due to the lack of a centralized licensing body for web data. The creation of centralized platforms, similar to stock photo websites, can simplify licensing, streamline access to data, and ensure data integrity against bias and discrimination.
    • Government and Judicial Approach to maximize the benefits of GAI: A comprehensive re-evaluation of existing digital jurisprudence is needed, requiring a holistic, government-wide approach and judicious interpretations by constitutional courts. The aim is to maximize the benefits of GAI while safeguarding individual rights and protecting against unwelcome harm.

  • On Improving Rural Mobile Connectivity 

    Why in the news? 

    On June 6, IEEE endorsed a wireless network structure aimed at providing economical broadband access in rural areas, formulated at IIT Bombay.

    About the latest Telecom Subscription Data        

    • Urban Tele-density: Urban tele-density in India is 127%, indicating that on average, each urban user has more than one mobile connection.
    • Rural Tele-density: Rural tele-density is significantly lower at 58%, meaning only about one in two rural residents has a mobile connection.
    • Urban-Rural Digital Divide: The data highlights a stark contrast between urban and rural areas, with urban areas having much higher mobile connectivity compared to rural regions, reflecting a significant digital divide.

    What are access and core networks?

    • Access Network (AN): The AN consists of base stations that provide wireless connectivity to mobile devices within a limited geographical area. It interfaces directly with mobile devices, facilitating communication and data transfer between devices and the wider network.
    • Core Network (CN): The CN comprises centralized network equipment that manages and directs data traffic between the access network, other networks (like the Internet), and service providers. It handles tasks such as routing, switching, and managing connectivity across the broader network infrastructure.

    What impedes rural connectivity?

    • Affordability: Lower income levels in rural areas make mobile services relatively expensive, limiting access for many rural residents.
    • Cost of Infrastructure: Installing and maintaining network infrastructure like fibre optics in remote rural areas is costly and may not be economically viable for service providers.
    • Low Population Density: Rural areas often have sparse populations spread over large geographic areas, making it less profitable for network operators to invest in infrastructure deployment.
    • Geographical Barriers: Difficult terrains and remote locations further complicate the installation of base stations and backhaul infrastructure necessary for robust network coverage.
    • Urban Bias in Technology: Most advancements in cellular networks, such as 5G, prioritize high data rates and low latency suitable for urban environments, neglecting the unique challenges of rural areas.
    • Limited Research: There has been insufficient research focused on developing cost-effective solutions that can efficiently cover large rural areas with adequate connectivity.

    What is the IEEE 2061-2024 standard? (Its working and architecture)   

    • IEEE 2061-2024 aims to establish a standardized wireless network architecture for affordable broadband access in rural areas.
    • It defines a heterogeneous Access Network (AN) comprising macro base stations (Macro-BS) and Wi-Fi base stations, integrated with a flexible Core Network (CN) bypass capability.

    Architecture:

    • Heterogeneous AN: Includes Macro-BS covering large areas with potentially lower data rates, complemented by Wi-Fi base stations deployed within villages for high-speed connectivity.
    • CN Bypass: Allows direct Internet access from the AN, bypassing the centralized Core Network for certain communications. This enhances efficiency and reduces latency, catering to stationary users common in rural settings.
    • Middle-Mile Connectivity: Utilizes multi-hop wireless networks (e.g., satellites, long-range Wi-Fi) to extend connectivity over long distances where optical fibre deployment is impractical or costly.

    What is a middle-mile network?

    • A middle-mile network refers to the infrastructure that connects core network hubs to local access points, spanning intermediate distances. It uses technologies like fibre optics, microwave links, or satellites to transport data between central and regional locations, facilitating efficient connectivity over longer distances without the need for direct local access networks.

    Conclude: To bridge the urban-rural digital divide in telecom, measures should focus on affordability through subsidized services, incentivizing infrastructure investment in rural areas, promoting research on rural-specific technologies, and ensuring equitable access to advanced wireless standards like IEEE 2061-2024.

  • [pib] Metal Oxide Nano-composite developed for Environmental Clean-up

    Why in the News?

     A new metal oxide nanocomposite has been developed by The Institute of Advanced Study in Science and Technology (IASST)  that can help photocatalytic degradation of organic pollutants like dyes and pharmaceuticals and hence can be used as sustainable technologies for cleaning up the environment.

    Understanding Photocatalysis and Metal Oxides

    • Photocatalysis is a process that uses light to accelerate chemical reactions, particularly useful for degrading harmful substances in water and air.
    • They facilitate this reaction without being consumed.
    • Examples: Titanium Dioxide (TiO2), Zinc Oxide (ZnO)  and Tungsten Trioxide (WO3)

    How do they work?

    • When exposed to light, these metal oxides generate electron-hole pairs.
    • These pairs are highly reactive and can break down pollutants into harmless by-products.
      • Work Efficiency: The overall efficiency of this process depends on several factors, including the choice of metal oxide, its crystal structure, light intensity, pollutant concentration, pH level, and the amount of catalyst used.
      • Optimisation: Optimizing these factors is crucial for maximising the degradation rates of pollutants. Adjustments in the type of metal oxide, light parameters, and other conditions can significantly enhance the photocatalytic efficiency.

    Breakthrough by IASST: NiTF Composite

    • The team developed a nanocomposite called NiTF, which stands for Nickel-doped Titanium Dioxide on Fuller’s Earth. 
    • This innovative material combines the photocatalytic properties of titanium dioxide with the adsorption capabilities of Fuller’s earth, a type of natural clay.

    What is Fuller Earth?

    • Fuller’s earth is a term for various clays used as an absorbent, filter, or bleaching agent.
    • Products labeled fuller’s earth typically consist of palygorskite or bentonite.
    • Primary modern uses include as absorbents for oil, grease, and animal waste, and as a carrier for pesticides and fertilizers

    Testing and Results

    • The NiTF nanocomposite was tested for its ability to decolorize methylene blue, a common dye.
      • Methylene blue is a persistent pollutant toxic to aquatic life, harmful to human health, and causes colour pollution in water bodies.
    • The results were impressive, with the composite achieving a 96.15% decolorization of the dye solution at a pH of 9.0 under visible light within 90 minutes.
    • Fuller’s earth enhanced the TiO2’s ability to adsorb pollutants, even in the absence of light.
    • This suggests that the NiTF nanocomposite could be a cost-effective solution for environmental photocatalysis, providing benefits even in low-light conditions.
