  • Polaris Dawn Mission: A Private Space Endeavor

    Why in the News?

    Polaris Dawn is set to be the first privately-funded mission to conduct a spacewalk, aiming to reach an altitude of about 700 kilometers above Earth, the highest altitude for a human space mission to date.

    What is Polaris Dawn Mission?

    • Polaris Dawn is a privately-funded space mission led by billionaire entrepreneur Jared Isaacman, in collaboration with SpaceX.
    • It is set to be the first non-government mission to conduct a spacewalk.
    • This 700km altitude will surpass the current record held by NASA’s Gemini 11 mission in 1966.
    • The mission will test new spacesuits designed by SpaceX to protect astronauts from high radiation levels encountered in the Van Allen Belts.

    What are the Van Allen Belts?

    • The Van Allen Belts are two zones of charged particles that surround Earth, held in the magnetosphere.
    • These belts were discovered in 1958 by American physicist James Van Allen.
    1. Inner Belt: This belt is located approximately 680 to 3,000 km above Earth’s surface and is primarily composed of high-energy protons. It is formed by cosmic rays interacting with Earth’s atmosphere.
    2. Outer Belt: Located about 15,000 to 20,000 km above Earth’s surface, the outer belt mainly consists of high-energy electrons captured from solar wind.

    Why are the Van Allen Belts dangerous for Humans?

    • The Van Allen Belts are dangerous for humans because they contain high levels of radiation that can pose significant health risks to astronauts.
    • The belts are filled with charged particles that can cause radiation sickness, damage human tissues, and increase the risk of cancer.

  • Why has Malaysia tweaked its ‘Orangutan Diplomacy’?

    Why in the News?

    Malaysia, after initially introducing its version of soft power called “Orangutan Diplomacy” following China’s successful “panda diplomacy,” has now reversed its decision.

    What is Orangutan Diplomacy?

    • It is a Malaysian strategy that seeks to use orangutan conservation as a tool of soft power, inspired by China’s “panda diplomacy.”
    • It had first announced plans to gift orangutans (IUCN Status: Critically Endangered) to palm oil-buying countries.
    • It engages other countries in conservation efforts, focusing on symbolic adoptions rather than sending animals abroad.
    • Reasons behind:
      • Palm Oil Industry Criticism: Malaysia faces criticism for deforestation due to palm oil plantations, threatening orangutans.
      • Enhance Image: It aims to counter negative perceptions and showcase commitment to sustainability and position Malaysia as a leader in wildlife protection.
      • Global Cooperation: It seeks to strengthen ties with major palm oil importers like China, India, and the EU through conservation partnerships.

    Criticisms:

    • Habitat Concerns: Critics argue real conservation requires protecting habitats, not just symbolic actions.
    • Comparisons to Panda Diplomacy: Malaysia’s effort lacks the infrastructure and commitment seen in China’s panda conservation.

    PYQ:

  • Imports weaken Indian pharma

    Why in the News?

    • The government has introduced two import-based initiatives to meet domestic needs, which could potentially dampen the growth of the domestic industry.
    • New medicines are generally under patent protection, preventing Indian companies from producing affordable generics/biosimilars.

    Impact of two initiatives on Domestic Industry:

    • Global Tendering for 120 Medicines: The Department of Expenditure (DoE) allowed the Ministry of Health to buy 120 medicines, including popular anti-diabetes and anti-cancer drugs, through global tenders for government programs. This decision, which specifies certain brands for over 40 of these medicines, could increase the monopoly of foreign companies in India.
    • Customs Duty Removal on Cancer Medicines: The 2024-25 Union Budget proposed removing the 10-12% customs duty on three cancer medicines marketed by AstraZeneca. While intended to reduce prices, this measure is unlikely to significantly lower costs and may instead increase reliance on imports, further disadvantaging domestic producers.

    Status of Indian Pharma

    • India is a leading manufacturer of vaccines, accounting for 60% of global production.
    • India supplies 70% of vaccines used by the WHO.
    • India is a major exporter of generic drugs, accounting for 20% of global exports.
    • The industry is expected to grow to over $130 billion by 2030.

    What are Biosimilar guidelines?

    • Biosimilar guidelines in India are regulatory frameworks established by the Central Drugs Standard Control Organization (CDSCO) and the Department of Biotechnology (DBT) to govern the development, approval, and marketing of biosimilars.
    • Biosimilars are biologic medical products that are highly similar to an already approved original biologic (known as the reference product), with no clinically meaningful differences in terms of safety, purity, and potency.

    Status Biosimilars: 

    • Significant Market Size: The biosimilar market in India is valued at approximately $2.2 billion, and it is projected to reach $40 billion by 2030. This growth is driven by the expiration of patents for several key biologics, which opens the door for biosimilar development.
    • Product Approvals: As of now, over 70 biosimilars have been approved in India, covering a range of therapeutic areas, including oncology, diabetes, and autoimmune diseases. Notable examples include:
      • Adalimumab (for rheumatoid arthritis)
      • Trastuzumab (for breast cancer)
      • Filgrastim (for neutropenia)
      • Insulin glargine (for diabetes)

    Outdated Biosimilar Guidelines in India:

    • Obsolete and Resource-Intensive:
      • India’s biosimilar guidelines are outdated, requiring mandatory animal studies, which are no longer necessary in developed countries like the U.S. and EU with stringent regulatory standards.
      • The guidelines also mandate clinical trials, while WHO and U.K. guidelines treat clinical trials as an exception rather than a rule.
    • Barrier for Domestic Producers:
      • The stringent requirements for animal studies and mandatory clinical trials create significant barriers for Indian producers, making it difficult for them to compete with their global counterparts.
    • Impact on Patient Access:
      • According to the International Generic and Biosimilar Medicines Association, eliminating these duplicative requirements could lead to significant savings in time and resources, ultimately improving patient access to affordable biosimilars.

    Way forward: 

    • Update Regulatory Guidelines: Modernize India’s biosimilar guidelines by removing unnecessary requirements like mandatory animal studies and clinical trials, aligning them with global standards to reduce barriers for domestic producers.
    • Support Local Production: Utilize provisions in the Patents Act to promote domestic manufacturing of affordable medicines, reducing reliance on imports and strengthening the local pharmaceutical industry.

  • What is Tera Hertz Spectrum?

    Why in the News?

    The Telecom Regulatory Authority of India (TRAI) released its recommendations on the Tera Hertz Spectrum.

    About Tera Hertz (THz) Spectrum

    • The THz Spectrum refers to a range of electromagnetic waves with frequencies between 100 GHz (gigahertz) and 10 THz (terahertz). 
      • This spectrum lies between microwaves and infrared light.
      • It is known as the “THz gap” because it has been less explored compared to other parts of the electromagnetic spectrum.

  • [21st August 2024] India’s Ethanol Blending Target: Progress, Challenges, and Regional Dynamics

    Why in the News? 

    India is on track to achieve its ambitious goal of blending 20% ethanol with petrol by 2025-26. While significant progress has been made in increasing ethanol production, the initiative is not without its challenges. The food versus fuel debate and concerns about fuel efficiency in existing vehicles continue to loom large over the ethanol economy.

    State of Ethanol Production in India

    • Dramatic Increase in Ethanol Blending: Ethanol blending percentage rose from 8% in 2021 to 13-15% in recent years. Significant progress indicates a strong push towards meeting the 20% blending target.
    • Substantial Investment in Production Capacity: The sugar industry has invested approximately ₹40,000 crore to boost ethanol production. This investment is key to increasing the country’s ethanol production capacity.
    • Nearing Production Targets: India is close to achieving its target of producing 1,380 crore litres of ethanol. Production contributions come from both sugarcane-based and grain-based distilleries.
    • Government Roadmap and NITI Aayog Projections: NITI Aayog’s roadmap called for a significant increase in ethanol production, with a focus on grain-based distilleries. By December 2023, nearly all ethanol capacity targets had been achieved. The expansion has primarily relied on sugarcane-based production.

    The Food vs. Fuel Debate & other Concerns

    • Food Security Concerns: The push for ethanol blending has raised alarms about its potential impact on food security. Increased use of food grains, particularly maize, for ethanol production is at the center of the concern.
    • Rising Maize Imports: Recent data shows an increase in maize imports from April to June this year.The rise is driven by higher demand for fuel ethanol and restrictions on using sugarcane products.
    • Price hike Concerns: Despite industry assurances of sufficient food stocks, the diversion of grains for ethanol production could lead to price hikes. Sectors like poultry, livestock feed, and starch production could be negatively affected.India’s maize yield is still below global averages, intensifying concerns about the strain on food supplies.
    • Water Usage Concerns: Expanding sugarcane production to meet ethanol targets has significant environmental implications, especially concerning water usage. Sustaining ethanol production from sugarcane may require an additional 400 billion litres of water.
    • Impact on Agricultural Sustainability: The increased water demand for sugarcane could divert irrigation resources from essential food crops. This diversion raises concerns about the long-term sustainability of agriculture in the region.
    • Competition for limited resources: Government policy supports using maize, surplus rice, and damaged grains for ethanol production. This approach could intensify competition for these resources, potentially impacting food availability.
    • Impact on Vehicle Efficiency: Ethanol has a lower energy content, which can reduce fuel efficiency in vehicles not designed for higher ethanol blends. A NITI Aayog report indicates that ethanol blending could decrease fuel efficiency by an average of 6% in such vehicles.

    The ongoing debate underscores the need to shift towards more sustainable 2G and 3G ethanol technologies. These advanced technologies have less impact on food security compared to 1G ethanol, which relies on food grains and sugarcane.

    Regional Variations in Ethanol Production and Policy

    Ethanol production and its economic impact vary widely across different Indian states, influenced by local economic priorities, agricultural practices, and policy frameworks.

    • Uttar Pradesh: As the largest contributor to India’s ethanol blending program, Uttar Pradesh is fully aligned with the central government’s ethanol mission. The state has reserved 25% of its ethanol production for Extra Neutral Alcohol (ENA), used in liquor production. However, the higher value of ethanol made from molasses, especially B-heavy molasses, has made fuel ethanol more attractive to distilleries.
    • Tamil Nadu: In Tamil Nadu, the lucrative liquor market dominates the ethanol economy, and fuel ethanol production has not gained as much traction. The state government controls the liquor market, and the high water requirements for sugarcane cultivation limit the expansion of ethanol production from this crop. There is also resistance to using rice for ethanol production due to its association with liquor.
    • Maharashtra: Maharashtra presents a different scenario, where ENA production for industrial uses, such as manufacturing and medicine, is more profitable than ethanol blending. However, there is potential for ethanol production to become more attractive if steady contracts for blending can be secured, reducing the need for additional processing after ensuring purity.

    Conclusion

    India’s ethanol blending program has made significant progress, but the challenges of balancing food security, agricultural sustainability, and vehicle efficiency must be carefully managed to ensure the initiative’s long-term success. The varying approaches and impacts across different states underscore the need for a balanced and inclusive strategy to achieve the national ethanol blending targets.

  • A ground plan for sustainable mass employment 

    Why in the News?

    The ambitious ₹2 lakh crore employment package aims to create 4.1 crore jobs, but evidence shows low wages and short-term skill programs hinder long-term sustainability.

    Low wages and short-term skill programs hinder long-term sustainability:

    • Low Wages Lead to Economic Insecurity: Low wages create economic insecurity for workers, making it difficult for them to meet basic needs. For instance, in the garment industry, there is a 48.5% gap between minimum wages and living wages in major garment-producing countries.
    • Short-Term Skill Programs Fail to Enhance Employability: Many short-term skill programs do not provide the depth of training needed for long-term employability. In India, for example, 75% of technical graduates and 90% of other graduates are considered unemployable, primarily due to a lack of practical skills and experience that employers seek.
    • Stagnation of Workforce Productivity: When workers are paid low wages, there is little incentive for them to enhance their skills or productivity. This stagnation is detrimental to both individual career growth and overall economic development.
    • Lack of Investment in Long-Term Skill Development: Low wages often correlate with limited investment in employee training and development.This is evident in the fact that only 15% of those trained under the Pradhan Mantri Kaushal Vikas Yojana (PMKVY) found jobs, indicating that short-term training initiatives are not effectively translating into sustainable employment outcomes.
    • Perpetuation of Poverty and Inequality: The combination of low wages and inadequate skill development contributes to the perpetuation of poverty and inequality. With 42% of the global workforce in vulnerable employment.

    12-point policy initiatives for sustainable mass employment:

    • Identify the skill need: Begin from below through decentralized community action to identify skilling needs. Create a register of those wanting employment/self-employment and a plan for every youth in partnership with professionals at the cluster level.
    • Initiative at the local level: Converge initiatives for education, health, skills, nutrition, livelihoods, and employment at the local government level with women’s collectives to ensure community accountability and effective outcomes.
    • Vocational programmes: Introduce need-based vocational courses/certificate programmes alongside undergraduate programmes in every college to improve employability.
    • Healthcare at international benchmark: Standardize nursing and allied health-care professional courses according to international benchmarks to meet the demand for skilled professionals.
    • Women security: Create community cadres of caregivers to run crèches universally so that women can work without fear.
    • Invest in skill development: Invest in ITIs, and polytechnics as hubs in skill development for feeder schools with a focus on States/districts with the least institutional structure for vocational education.
    • Startup skills in high school: Introduce enterprise and start-up skills through professionals in high schools to impart finishing skills to students.
    • Apprenticeship program in Industry: Have a co-sharing model of apprenticeships (combine practical training in a job with study) with the industry on scale to ensure the industry has a stake in the apprenticeship program.
    • Absorption of youth at the workplace: Apprenticeships on the scale can facilitate the absorption of youth in the workplace, with the government’s condition for employer subsidies being wages of dignity on successful completion of the apprenticeship.
    • Capital oan for women: Streamline working capital loans for women-led enterprises/first-generation enterprises to enable them to go to scale.
    • Skill accreditation programme: Start a universal skill accreditation programme for skill-providing institutions, with candidates co-sponsored by the state and employers.
    • Majority of fund in water scares block: Use 70% funds under MGNREGA in 2,500 water-scarce blocks and blocks with high deprivation, with a thrust on the poorest 20 families and a focus on skills for higher productivity.

    Way forward: 

    • Strengthen Industry-Academia Linkages: Enhance collaboration between educational institutions, industry, and vocational training centers to align curricula with industry needs, ensuring employability through internships, apprenticeships, and job placements.
    • Focus on Inclusive Skill Development: Prioritize investment in underdeveloped regions and marginalized groups by expanding access to quality education, vocational training, and entrepreneurship opportunities, especially for women and youth, to bridge the skill gap and promote economic inclusion.

  • Can blood tests for cancer save more lives? 

    Why in the News?

    A multi-cancer early detection test can identify circulating tumour DNA or circulating tumour cells at an early stage, allowing for more effective treatment.

    Status of Cancer:

    • Cancer’s Impact in India: Cancer accounts for 18% of deaths from noncommunicable diseases in India, making it the second leading cause of mortality. In 2022, there were approximately 1.46 million new cancer cases, with projections indicating a 12% increase by 2025.
    • Common Cancers as per GLOBOCAN: Among women, the most prevalent cancers are breast, cervical, ovarian, and colorectal.
      • For men, lung, esophageal, colorectal, and stomach cancers are the most common.
    • Survival Rates and Detection: Late detection of cancer significantly reduces survival rates and increases treatment costs. In contrast, early detection through screening improves treatment outcomes and quality of life. 
      • Countries are aligning with the United Nations’ Sustainable Development Goals 3 to enhance early cancer detection.
    • Limited screening: As per NHFS, screening is limited in India which is primarily to cervical, breast, and oral cancers, with only 0.2-2% of the population having undergone any form of screening.

    What is a Multi-Cancer Early Detection (MCED) Test?

    • A multi-cancer early detection (MCED) test is a new type of blood test that can screen for multiple types of cancer simultaneously. These tests look for cancer signals, such as circulating tumor DNA (ctDNA) and circulating tumor cells (CTCs), released by cancerous cells into the bloodstream at early stages.

    Role of Blood-based tests in the detection of cancer:

    • Early Detection of Multiple Cancer Types: Blood tests, particularly multi-cancer early detection (MCED) tests, can identify cancer signals from over 50 different types of cancer, including those that currently lack effective screening methods.
      • For example, a recent study demonstrated that a new blood test could detect 93% of stage 1 cancers in men and 84% in women by analyzing protein biomarkers.
    • Non-Invasive and Accessible Screening: Blood tests are non-invasive and can be performed with a simple blood draw, making them more accessible compared to traditional screening methods like colonoscopies or imaging tests. This ease of use encourages more individuals to participate in screening.

    Limitation of blood test in the detection of Cancer:

    • Lack of Proven Mortality Benefit: It is still unclear whether detecting cancers earlier with MCED tests will actually reduce cancer deaths. More research is needed to determine if earlier treatment based on MCED results improves outcomes compared to waiting for symptoms to develop.
    • Regulatory Challenges: MCED tests are not yet approved by regulatory bodies like the U.S. FDA or India’s CDSCO because of not undergone rigorous premarket review to prove they benefit patients.
    • False Positives: One significant risk is false positive results, where the test indicates cancer when none is present. When multiple tests are used for screening, the false positive rate can be as high as 50%.

    Way forward:

    • Strengthening Screening Infrastructure and Research: India should invest in expanding its cancer screening infrastructure, ensuring that more types of cancer are included beyond cervical, breast, and oral cancers.
    • Public Awareness and Regulatory Preparedness: Increasing public awareness about the importance of early cancer detection is crucial. At the same time, regulatory bodies like CDSCO should establish clear guidelines and frameworks for the evaluation, approval, and monitoring of MCED tests.
