Context: The 2023 Nobel Prize in Chemistry has been awarded to Alexei Ekimov, Louis Brus, and Moungi Bawendi for their work on quantum dots.
Basic background:
Fundamental facts of Chemistry:
Every element exhibits specific properties determined by the number of electrons in its atoms and the distribution of these electrons around the nucleus.
So, every piece of a pure element exhibits the same properties regardless of its size.
Particles in the nanoscale range behave slightly differently from larger particles of the same element. E.g., A nanoparticle of gold (sizes in the range of 1 to 100 billionth of a metre) displays properties different in some respects from larger particles of gold.
Reasons for deviation: This is because when the size of the particles is reduced to the nanoscale, electrons in the atoms find themselves squeezed or constrained in a small space giving rise to quantum effects.
The Nobel-winning research:
The scientists were independently successful in developing efficient methods to produce nano-sized particles that behaved slightly differently than larger particles of the same element. These nanoparticles with special properties were called quantum dots.
Quantum dots:
Quantum dots are tiny particles or nanocrystals of semiconducting material with a diameter in the range of 2–10 nm (10–50 atoms).
QDs are nanosized in all three dimensions and are made from a semiconductor such as Silicon.
They behave like artificial atoms, as they can have a fixed number of electrons in a confined space, leading to unique properties that are size-dependent.
QDs exhibit special properties when they interact with light.
In general, the colour of any material depends on the wavelengths of the light spectrum absorbed or reflected by the material.
However, quantum dots made from the same material will re-emit/give out different colours of light depending on their size. The biggest quantum dots produce the longest wavelengths (and lowest frequencies), while the smallest dots make shorter wavelengths (and higher frequencies).
Applications:
Bioimaging: QDs are considered to be superior to traditional organic dyes and can be used in bioimaging.
QDs are 20 times brighter and 100 times more stable than traditional fluorescent dyes.
Unlike organic dyes, which operate over a limited range of colours and degrade relatively quickly, quantum dyes are very bright, can be made to produce any colour of visible light, and last indefinitely as they are photostable.
Bio-sensors: QD sensors can detect the presence of pathogens in food or water, or monitor the levels of pollutants in the environment.
QDs exhibit specific optoelectronic properties. They can be used for fluorescence imaging where quantum dots are injected into the body, which when encounters a cancer cell, attaches to it. When a light of a certain frequency is shined, QD lights up and doctors can exactly target these cells.
QDs can be targeted at single organs much more precisely than conventional drugs, reducing the side effects characteristic of untargeted, traditional chemotherapy.
Because of their nano size; they possess a large surface area ensuring higher drug loading capacity and can tag the nanocarriers in biological systems.
Optical applications:
Due to their unique optical properties, QDs could be used to make smaller and more efficient image sensors like CMOS sensors.
QDs can be used in computer screens and displays due to their important advantages:
QLEDs are capable of emitting all colours depending on their size. Thus, they provide high-definition, brighter and more colourful displays. Quantum dots are brighter than organic LEDs (OLEDs).
QDs produce light themselves and need no backlight which makes them energy efficient.
Photovoltaic devices: QDs have the potential to boost the efficiency of silicon photovoltaic cells.
Photonics: QDs are best suited for photonics-based computing capable of achieving high speeds.
Context: The Members of the Royal Swedish Academy of Sciences announced the Nobel Prize winners in Physics for 2023 for experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter.
Nobel Prize in Physics:
France’s Pierre Agostini, Hungarian-Austrian Ferenc Krausz and French-Swedish Anne L’Huillier won the Nobel Prize in physics for experimental methodsthat generate pulses of lightmeasured in the attosecond (10-18 seconds) that enable the study of electrons inside atoms and molecules using attosecond spectroscopy.
Electron movements in atoms and molecules are so rapid that they are measured in attoseconds. An attosecond is to one second as one second is to the age of the universe.
Basic background:
Analogy: In our everyday lives, we are unable to observe the processes completely that happen fast. For example, when a bullet is fired at an apple, we see the outcome — a smashed apple — but are unable to capture the entire process which takes barely a few milliseconds. However, a camera having a very high shutter speed makes it possible to see every step of the bullet piercing the apple and coming out of it, destroying the apple in the process.
Dynamics at Atomic scale: At atomic and subatomic levels, processes (movement of electrons, or energy dynamics) happen at an incredibly fast rate, i.e., they take just a few picoseconds (a trillionth of a second, or 10-12 seconds) or femtoseconds (10-15 seconds). To observe these processes, scientists use unimaginably short pulses of light, like using extremely high shutter-speed cameras. But then they hit a barrier.
Existing challenges at sub-atomic scale:
To observe any process, measurement must be made at a pace quicker than the rate of change.
Light pulses which are the only plausible tool to capture processes at the atomic level cannot be made indefinitely shorter.
Light consists of waves or vibrations in an electromagnetic field. The shortest possible pulse would have to be at least one cycle long, equivalent to its wavelength.
Attoseconds science:
Femtosecond pulses have enabled scientists to observe the processes happening at the atomic or molecular level.
But at the sub-atomic level, dynamics of sub-atomic particles happen even faster, at the level of attoseconds. Ex. Dynamics of electrons are 100 to 1,000 times faster than that of an atom. (Lower the inertia, faster the dynamics).
These femtosecond pulses were longer than the sub-atomic motion that was happening in a matter of attoseconds and the production of shorter pulses of light, in the attosecond range, did not seem possible.
So, Scientists were unable to glimpse the motion of electrons with existing technologies, as for a long time, femtosecond ‘photography’ was considered the limit.
Nobel-winning research:
The works of Pierre Agostini, Ferenc Krausz and Anne L’Huillier made it possible to observe phenomena happening at the timescale of Attoseconds as they demonstrated a way to create extremely short pulses of light that can be used to measure the rapid processes at which electrons operate.
Working independently, the scientists devised experimental methods by mixing lights of different wavelengths to produce attosecond pulses of light which can enable the exploration of electron-dynamics in matter.
The observation of every step of a process is necessary to fully understand it.
It has made it possible to examine the rapid moves or changes in sub-atomic scales and allows scientists to control the process by tweaking the intermediate steps and obtaining desired results.
Potential Applications:
Attosecond science has potential applications in a variety of areas, from electronics to medicine, across disciplines in physics, chemistry and biology.
In Electronics:
Help to measure the time it takes for an electron to be tugged away from an atom and to examine how the time this takes depends on how tightly the electron is bound to the atom’s nucleus.
Reconstruct how the distribution of electrons oscillates from side to side in molecules and materials, earlier the distribution of electrons could only be measured as an average.
Test internal processes of matter and identify different events.
Attosecond physics can enable us to understand and control how electrons behave in a material.
Help in designing more efficient electronic gadgets.
In Medicine:
Attosecond pulses can be used to identify different molecules, such as in medical diagnostics. Study molecular-level changesin blood to identify diseases.
Krausz group has developed a new in vitro diagnostic analytical technique to detect characteristic molecular traces of diseases in blood samples. This technique allows monitoring of many molecules at the same time and the radiation is non-ionising and therefore not harmful.
Context: The Pink Bollworm pest has infected the Cotton Crop in the states of Haryana and Rajasthan.
Pink Bollworm
Pink Bollworm is considered possibly the most destructive peston cotton worldwide.
It is native to India but is now found in nearly all the cotton-growing countries of the globe.
Description: The larvae have distinctive pink bands, and the larval stage, is the most destructive and identifiable stage. The adults are small moths about 3/8 inch long.
Threat:
Adults lay eggs on cotton bolls; once hatched, the larvaeburrow into the developing fruits (bolls) of cotton plants, eat the seeds and damage the fibres of the cotton.
The damage affects both the weight and quality of the harvested bolls containing the lint fibre and seeds inside, thus, reducing both the yield and quality.
When the larvae mature, they cut out the boll and drop to the ground and cocoon near the soil surface.
The larvae can also survive in the seed after the ginning process and if the seed is not fumigated, they will emerge from the stored seed the next spring.
Apart from cotton, they can also attack hibiscus and okra.
What’s the issue?
The Pink Bollworm (PBW) infestation has been common in the cotton belt of northern Rajasthan, Haryana and Southwestern Punjab since 2021. However, the damage reported is much more widespread and serious in 2023.
The Bt cotton – which incorporates genes from a soil bacterium that codes for proteins toxic to the American bollworm – haslost its efficacy against the Pink Bollworm.
The pink bollworm infestation is higher this year because of early rains making it conducive for the worms to grow and fester.
Bt Cotton:
Bt cotton is a genetically modified pest-resistant plant cotton variety modified by the insertion of one or more genes (Cry1 Ac) from the soil bacterium, Bacillus thuringiensis.
Strains of the bacterium Bacillus thuringiensis produce toxins that are harmful to a variety of insects and it has been found to combat American bollworm – moth larvae that commonly attack cotton crops.
Bt cotton is India's first transgenic crop formally approved for commercial cultivation in 2002.
Aim of introducing Bt cotton to India was to reduce the amount of insecticide needed in farming cotton.
Benefits: Reduction in production cost, increase in profit, reduced farming risk and improved economic outlook for cotton, does not harm non-target beneficial insects, helpful in improving wildlife population, reduced run-off of insecticides and air pollution.
Context: Recently, India reached out to Australia to procure monoclonal antibodydoses to combat the Nipah virus outbreak in Kerala. The dosage has to be administered at an early stage of infection.
What is an antibody?
They are proteins produced by the immune system that neutralize any foreign substance (bacteria, virus) entering the human body.
An antibody attaches itself to an antigen – a foreign substance, usually a disease-causing molecule – and helps the immune system eliminate it from the body.
What is a monoclonal antibody?
Monoclonal antibodies are laboratory-made proteins that mimic the behaviour of antibodies produced by the immune system to protect against diseases and foreign substances.
Monoclonal antibodies are specifically designed to target certain antigens.
How do monoclonal antibodies work?
Monoclonal antibodies are specifically engineered and generated to target a disease. They are meant to attach themselves to the specific disease-causing antigen. An antigen is most likely to be a protein.
For example, most successful monoclonal antibodies during the pandemic were engineered to bind to the spike protein of the SARS-CoV-2 virus. The binding prevented the protein from exercising its regular functions, including its ability to infect other cells.
What is m102.4?
m102.4 is a monoclonal antibody that binds itself to the immunodominant receptor-binding glycoprotein of the Nipah virus, potentially neutralising it. m102.4 neutralises Hendra and Nipah viruses both outside and inside of living organisms.
Both Hendra and Nipah viruses are a family of viruses that contain a single-strand RNA of the negative-sense genome, similar to the ones that cause diseases like measles, influenza etc., and replicate within infected cells.
Manufactured by: Australian Institute for Bioengineering and Nanotechnology (AIBN), University of Queensland.
The antibody has passed phase-one clinical trials — which means that researchers tested it with a relatively small number of people to estimate the right dose of treatment that also does not cause side effects.
As of now, the drug is used on a ‘compassionate use’ basis — a treatment option that allows the use of an unauthorised medicine under strict conditions among people where no other alternative and/or satisfactory authorised treatment is known to be possible and where patients cannot enter clinical trials for various reasons.
About Nipha Virus (NiV):
Transmission: Nipah virus is a zoonotic disease that can be transmitted to humans through direct contact with infected animals, especially bats and pigs. Nipah virus infection can be transmitted through contaminated food or directly from person to person.
Natural Reservoir: Fruit Bats (also known as flying foxes) are believed to be the natural reservoir/primary carriers of the Nipah virus.
Symptoms:
Fever, muscle pain, and respiratory problems (similar to that of influenza).
Inflammation of the brain as well as late onset of Encephalitis can also occur.
The case fatality rate is between 65 percent and 100 percent.
Treatment: NiV is on the top-10 priority list of pathogens identified by the World Health Organization. Currently, there are no approved vaccines available against NiV.
Context: In a paper in Nature Physics, a researcher at Google Quantum AI reportedly demonstrated a problem that is difficult for classical computers. If a quantum computer solves this problem, it can achieve quantum supremacy.
Quantum Supremacy (QS)
When a quantum computer outperforms a classical supercomputer on a well-defined computer science problem, this achievement is known as quantum supremacy.
Superposition states allow qubits to carry more information.
Because of quantum superposition, a quantum computer can mimic several classical computers working in parallel.
This capacity of doing several computations in parallel gives quantum computers an advantage over classical computers, allowing them to perform a disproportionately greater number of operations.
Google’s quantum computer, named Sycamore, claimed ‘supremacy’ because it reportedly did the task in 200 seconds that would have apparently taken a supercomputer 10,000 years to complete.
Supercomputer
Supercomputer is a class of extremely powerful computers. The term is commonly applied to the fastest high-performance systems available at any given time.
The performance of a supercomputer is commonly measured in floating-point operations per second (FLOPS) instead of million instructions per second (MIPS).
Since 2017, there have existed supercomputers which can perform over 1017 FLOPS (a hundred quadrillion FLOPS, 100 petaFLOPS or 100 PFLOPS.
These are very large classical computers, often with thousands of classical CPU and GPU cores capable of running very large calculations and advanced artificial intelligence.
Need of Quantum Computers
Even supercomputers are binary code-based machines reliant on 20th-century transistor technology. They struggle to solve certain kinds of problems.
When classical computers fail, it's often due to complex problems which are problems with lots of variables interacting in complicated ways.
There are some complex problems that we do not know how to solve with classical computers on any scale.
The real world runs on quantum physics. Computers that make calculations using the quantum states of quantum bits should in many situations be our best tools for understanding it.
Quantum Computing
A quantum computer is a computer that takes advantage of quantum mechanical phenomena.
Quantum computers are machines that use the properties of quantum physics to store data and perform computations.
This can be extremely advantageous for certain tasks where they could vastly outperform even our best supercomputers.
Classical computers, which include smartphones and laptops, encode information in binary “bits” that can either be 0s or 1s.
In a quantum computer, the basic unit of memory is a quantum bit or qubit.
Quantum computing is driving new discoveries in healthcare, energy, environmental systems, smart materials, and beyond.
Qubit
Just like a binary bit is the basic unit of information in classical computing, a qubit is the basic unit of information in quantum computing.
Qubits vs Bits
Qubits are represented by a superposition of multiple possible states.
A qubit uses the quantum mechanical phenomena of superposition to achieve a linear combination of two states.
A classical binary bit can only represent a single binary value, such as 0 or 1, meaning that it can only be in one of two possible states.
A qubit, however, can represent a 0, a 1, or any proportion of 0 and 1 in superposition of both states, with a certain probability of being a 0 and a certain probability of being a 1.
There are many physical implementations of qubits
Where classical computers use familiar silicon-based chips, qubits (sometimes called "quantum computer qubits") can be made from trapped ions, photons, artificial or real atoms, or quasiparticles.
Depending on the architecture and qubit systems, some implementations need their qubits to be kept at temperatures close to absolute zero.
Qubits are fragile
One of the most significant hurdles in quantum computing is the fragile nature of qubits.
Entanglement of the qubit system with its environment, including the measurement setup, could easily perturb the system and cause decoherence.
Entanglement
Multiple qubits can exhibit quantum entanglement.
Entangled qubits always correlate with each other to form a single system.
Even when they're infinitely far apart, measuring the state of one of the qubits allows us to know the state of the other, without needing to measure it directly.
Entanglement is required for any quantum computation, and it cannot be efficiently performed on a classical computer.
Applications include factoring large numbers (Shor's algorithm) and solving search problems (Grover's algorithm).
Superposition
Superposition is a phenomenon in quantum computing that allows quantum objects to simultaneously exist in more than one state or location.
This means that an object can be in two states at one time while remaining a single object.
Quantum computers use the entanglement of qubits and superposition probabilities to perform operations.
Superposition enables the qubits of the quantum computer to perform multiple operations simultaneously, making them faster than conventional computers.
Superposition gives quantum computers superior computing power
Superposition allows quantum algorithms to process information in a fraction of the time it would take even the fastest classical systems to solve certain problems.
The amount of information a qubit system can represent grows exponentially for example Information that 500 qubits can easily represent would not be possible with even more than 2^500 classical bits.
It would take a classical computer millions of years to find the prime factors of a 2,048-bit number, Qubits could perform the calculation in just minutes.

Challenges with Initiatives taken by government
Policy gaps: India has loosely built quantum ecosystem where metrics to assess outcomes of its quantum efforts are not clearly defined. E.g., lack of target-oriented policies.
Raising funds: Indian quantum computing startups struggle with funds for product development and scaling due to low venture capital investment. E.g., the budgeted R&D outlay is less than 1%.
Insufficient talent pool: India has small pool of researchers, industry professionals, academicians, and entrepreneurs as compared to China or the US. E.g., problem of brain-drain, inadequate infrastructure and research facilities.
Poor-infrastructure: India lacks in hardware manufacturing and still imports critical quantum components. India also lacks sufficient superconducting materials, semiconductor chips, processors, and fabrication labs.
R&D in silos: India lacks common platform for all quantum research and development. At present, research is carried out in silos and knowledge exchange is not structured. E.g., no common platform to transmit real-time data of research in quantum computing.
Lack of industry connection: Most quantum-related R&D is carried out in universities. While academia can provide well-researched prototypes; industry connection is essential for developing scalable applications.
Way Forward:
Rework Indian technology policy objectives, frameworks, and deliverables to move from importer of quantum technology to exporter.
Developing knowledge ecosystem by inculcating entrepreneurship, innovation, university courses, training programmes in quantum technology.
Develop metrics to assess success of strategy and short & long-term action plan.

Boost to investor ecosystem to amplify production of hardware components of quantum computer plus simultaneous push to semiconductor industry.
Context: Bihar is all set to get its second tiger reserve in Kaimur district by the end of the year or early 2024. The NTCA had, in principle, approved our proposal in July for the tiger reserve. The department has now started preparing for the final submission to be sent to the NTCA for its formal approval.
About Kaimur Wildlife Sanctuary
Kaimur Wildlife Sanctuary of Rohtas Forest Division is situated in the great Kaimur Range hills in the Rohtas District of Bihar.
KWLS came into existence in 1979 (the later area was increased in 2010) with an area of over 1784.73 sq km.
It is the largest and first wildlife sanctuary to be declared in the State of Bihar.
The KWLS is spread in Bhabhua and Rohtas District of the State of Bihar.
Habitats offered by deep valleys (locally known as khoras) and high hills (locally known as Ballas), daunted with rivers and nallahs having water all year round in the ‘doh’.
Rohtasgarh Fort and Shergarh Fort are also located in these forests.
It also has numerous Megaliths, Rock paintings of prehistoric age and stone inscriptions from a bygone era.
The Government of Bihar has planned to develop it into a Tiger Reserve.
This Wildlife Sanctuary is located in the Rohtas Plateau and Kaimur plateau of Kaimur Range in the south-western part of Bihar.
This forms the watershed or divide for two of the major rivers of peninsular India, the Son on the south and Tamsa or Tons on the north.
The sanctuary forms an essential corridor between forest areas of Bihar, Jharkhand Chhattisgarh and Uttar Pradesh ensuring the contiguity of forests in Vindhya.
In the valley portions, there are several waterfalls of which the finest are Karkat Waterfall, Manjhar Kund, Dhua Kund, Tutla Bhawani Waterfall, Geeta Ghat Waterfall, Kashish Waterfall, and Telhar.
There are several Dams and lakes, including Anupam Lake, Karamchat Dam and Kohira Dam.
Anupam Lake and Kalidah near Rameshwar Kund are located in the lake.
The major forest types are Tropical Dry Mixed Deciduous, Dry Sal Forests, Boswellia Forests and Dry Bamboo Brakes.
Important Fauna of Sanctuary
It harbours several other faunal species some of which figure in the IUCN Red Data List. These are Leopard, Indian Pangolin, Porcupine, Wild dogs, Jackal, Sloth bear.
The Crested eagle and Hawk eagle’s presence in Rohtas forests indicates the ecological sustenance of the area.
It is home to many migratory birds, such as the lesser white-fronted goose, ferruginous duck, Baer's pochard duck and lesser adjutant, greater adjutant, black-necked stork, and Asian openbill stork migrate from Central Asia to the park during winter.
Among snakes, cobras and kraits are of common occurrence while pythons are occasionally seen.
Context: The microbiome research has gone from a ‘niche subject area’ to ‘one of the hottest topics in all of science’. Researchers have thrown light into the human microbiome — the community of microbes living in the human body.
Human Microbiome:
Human Microbiome is the aggregate of all microbiota that reside on or within human tissues and biofluids along with the corresponding anatomical sites in which they reside, including the skin, mammary glands, seminal fluid, uterus, ovarian follicles, lung, saliva, oral mucosa, conjunctiva, biliary tract, and gastrointestinal tract.
Types of human microbiota include bacteria, archaea, fungi, protists, and viruses.
In the context of genomics, the term human microbiome is sometimes used to refer to the collective genomes of resident microorganisms; however, the term human metagenome has the same meaning too.
Benefits of Microbiome:
Facts about Human Microbiome:
Every adult ends up with a unique microbiota configuration, even identical twins that are raised in the same household.
Mothers do not pass their microbiomes to their children at birth. Some microorganisms are directly transferred during birth but they constitute a small fraction of the human microbiota; and only an even smaller fraction of these microbes survive and persist throughout the child’s life.
Diseases are caused by undesirable interactions between microbial communities and our cells. Whether a microbe and its metabolite are ‘good’ or ‘bad’ depends on the context. For example, most humans carry a species of bacteria called Clostridium difficile without any disease for life. It causes problems only in the elderly or in people with compromised immune systems.
The absolute microbial cells in one gram of human faeces are around 10^10 to 10^12. The human microbiota weighs about half a kg or less.
Probiotics:
Probiotics are foods or supplements that contain live microorganisms (live beneficial bacteria and/or yeasts) intended to maintain or improve the "good" bacteria (normal microflora) in the body.
Context: The National Research Foundation (NRF), a new research funding agency, was approved by the Union Cabinet recently.

Debate: Funding Priorities and Innovation Models
This debate revolves around the question of whether research funding should be driven primarily by curiosity-driven scientific exploration or whether it should be directed toward solving practical problems and addressing societal challenges.
Vannevar Bush’s Argument about Research Funding
One perspective, as articulated by Vannevar Bush in his 1945 paper, suggests that scientific research should be driven by the "free play of free intellects" guided by curiosity rather than immediate practical utility.
This perspective argues that many significant discoveries and innovations have arisen unexpectedly from such unfettered exploration.
In this view, the government's role is to invest in scientific research, trusting that these discoveries will eventually find their way into practical applications, often through private sector innovation.
Many important technologies have benefited from discoveries driven by curiosity, including genome-sequencing, medical diagnostics, and several materials used in construction and various goods.
Daniel Sarewitz’s Counterargument about Research Funding
Contrary to the "free play of intellects" argument, Daniel Sarewitz's essay "Saving Science" argues that many important innovations, especially in the postwar United States, were driven more by the practical needs of entities like the Department of Defense (DOD) than by curiosity.
The DOD provided critical investment and direction for fundamental research in various fields, leading to innovations such as computers and, indirectly, the World Wide Web.
This view suggests that government involvement and direction can be essential for driving innovation in specific directions.
National Innovation System
The National Innovation System focuses on promoting connections and collaboration between universities, research institutes, companies, and governments to promote innovation.
This model is based on the idea that innovation to flourish a country need fostering connections, promoting learning within systems, and empowering entrepreneurship.
Countries like Japan and South Korea owe their innovation-led economic growth to the successful implementation of an interconnected innovation system, e.g., between automobiles companies and part suppliers, even though their basic science was not particularly strong in the 1970s-80s.
Emerging Sustainability Model
This model emphasizes transformative change toward sustainability.
This model acknowledges that science, technology, and innovation (STI) should not only drive economic growth but also work toward environmental and social sustainability.
It advocates for citizen science and stakeholder participation to guide research priorities and solutions.
In the face of the energy crises of the 1970s, Denmark’s grassroots environmental movement created local cooperatives and small firms that experimented with wind turbines, with support from national technological institutes and policies (feed-in tariffs).
This coalition eventually led Denmark to become one of the leading exporters of wind-turbines, contributing to its transition to green energy.
Need of NRF for India

Striking the right balance between international and domestic collaborations can be challenging.
Evaluation and Impact Assessment: Ensuring that funded projects lead to tangible outcomes and societal benefits can be challenging, and concerns may arise if the impact assessment process is not rigorous.
Long-Term Sustainability:
The long-term sustainability of the NRF's funding and operations may be a concern.
It is essential to ensure that the NRF continues to receive adequate funding and support over the years to fulfill its mission effectively.
Stakeholder Engagement:
Engaging with diverse stakeholders, including researchers, industry, and civil society, is crucial for effective research policy.
Concerns may arise if there is insufficient consultation with stakeholders in shaping the NRF's priorities and strategies.
Research Ethics and Integrity:
Ensuring that research funded by the NRF adheres to ethical standards and maintains research integrity is vital.
Concerns about ethical violations or research misconduct could undermine the credibility of funded projects.
The establishment of NRF is a step in the right direction to improve research funding, stopping brain-drain and making India a global research hub. But it also faces certain practical concerns in its implementation, addressing these concerns requires a commitment to transparency, accountability, and a rigorous evaluation process. It is essential for the NRF to operate independently, free from political influence, and with a focus on promoting high-quality research that benefits society and advances knowledge. Regular reviews and adjustments to policies and procedures can help mitigate these concerns and ensure the NRF's effectiveness in fostering research and innovation in India.
Context: The OSIRIS-REX mission has ended with the return of regolith (space sample) from the primordial asteroid Bennu.
OSIRIS-RExMission:
Origins, Spectral Interpretation, Resources Identification and Security-Regolith Explorer (OSIRIS REx) is an asteroid study and sample return mission by NASA.
The spacecraft set out in 2016 to study asteroid Bennu (a carbon-rich near-Earth asteroid) and return to Earth with a sample for detailed analysis in 2023.
Asteroid Bennu:
Bennu is a small asteroid, a little less than 500 metres in depth and is more than 4.5 billion years old.
It is classified as a “near-Earth object” because it passes relatively close to our planet every six years.
Over time, the asteroid has drifted closer to Earth, closely approaching it every six years, owing to which it has a small chance of impacting the Earth in future (2182 CE).
Why was Bennu chosen?
Bennu fits in three criteria: accessibility, size and composition.
For a mission like OSIRIS-REx, the most accessible asteroids are somewhere between 0.08 – 1.6 AU. Scientists needed an asteroid that could be easily travelled to, retrieve a sample from and return to Earth all within a few years. Further, Bennu had an orbit similar to Earth.
One theory is that small worlds like Bennu seeded Earth with the prebiotic ingredients for life
Significance:
Researchers believe that this pristine space dirt will reveal clues about the birth of our solar system (4.5 billion years ago) and the genesis of life on Earth.
Key Fact:
One AU (Astronomical Unit) is approximately equal to 93 million miles - the distance between the Sun and the Earth. The closest asteroids which travel within 1.3 AU of the sun are called near-Earth objects.
Context: On April 13, 2021, Japan’s government announced plans to release over one million tonnes of contaminated water from the Fukushima nuclear plant into the sea over the next 30 years.
The wastewater is a by-product of the catastrophic 2011 earthquake and tsunami, which disabled the Fukushima Daiichi nuclear power plant, leading to the release of radioactive materials. After more than a decade of storing this wastewater, Japan says they are running out of storage space, and allege that the, now treated water is safe for release.
How is the water being treated and what is the controversy?
The water is being treated by the Tokyo Electric Power Company (TEPCO).
The water has been treated with multiple techniques, notably the Advanced Liquid Processing System (ALPS), which removes 62 types of radioactive materials.
However, it doesn’t remove tritium.
TEPCO and the Japanese government argue that the concentration of tritium does not exceed international standards, in particular, those of the International Atomic Energy Agency (IAEA), the United Nations’ nuclear watchdog. According to TEPCO’s website, the radiation emitted by tritium is “extremely weak, and can be blocked with a single sheet of paper.” The concentration is also six times less than the limit for tritium in drinking water, set by the World Health Organization.
You can’t remove tritium because it is identical to hydrogen. So removing it, chemically extracting it from wastewater becomes quite impossible.
Fears persist within the majority. A poll conducted by Japan’s Jiji Press in September shows that 16.3% of respondents are opposed to the discharge of the treated water, and 30.8% were neither opposed nor in favour. Several protests have been held in Seoul against the release, and many hoarded seafood ahead of the discharge. Some surveys show that 8085% of South Koreans oppose the water’s release. The Chinese government, which has been against Japan’s decision since the announcement was made, has already banned seafood from Japan.
ANALYSING NUCLEAR ENRGY AS A WHOLE:
Points in favour of nuclear energy:
Nuclear is a zero-emission clean energy source: It generates power through fission, which is the process of splitting uranium atoms to produce energy. The heat released by fission is used to create steam that spins a turbine to generate electricity without the harmful by-products as emitted by fossil fuels. Fig: A comparison of direct GHG emission (red bars) and full life cycle emissions (blue bars)
Nuclear energy’s land footprint is small: Despite producing massive amounts of carbon-free power, nuclear energy produces more electricity on less land than any other clean-air source. A typical 1,000-megawatt nuclear facility needs a little more than 1 square mile to operate which is 360 times less than wind plant and 75 times less than solar plant.
Nuclear energy produces minimal waste: Nuclear fuel is extremely dense. It’s about 1 million times greater than that of other traditional energy sources and because of this, the amount of used as nuclear fuel is not as big as you might think.
Nuclear power is not without significant disadvantages and risks that warrant consideration:
Safety concerns: Nuclear accidents like Chernobyl and Fukushima have demonstrated the catastrophic dangers of nuclear power when safety systems fail. In Indian context high population density, limited water resources and seismic instability in some regions amplify the risks and potential impacts of an accident should one occur..
Weapons proliferation: Nuclear technologies and by-products like plutonium can potentially enable weapons proliferation if misused or mishandled. India must ensure its ambitious nuclear plans strengthen oversight, safeguards and the civilian orientation of its programs to avoid enabling weapons ambitions in unstable regions.
Costs: Although nuclear energy is inexpensive once operational, nuclear power plants are highly capital intensive to construct. Project cost overruns are common. Ex: Flamanville reactor in France is 10 years behind schedule and costs have tripled to $12.7 billion. High costs could deter investment into nuclear and benefit cheaper renewable sources.
Waste disposal: Nuclear plants generate radioactive waste that remains dangerous for thousands of years and there are unresolved issues around waste storage and disposal. Any country pursuing nuclear must develop safe, long-term waste solutions to avoid contamination.
Opportunity costs: Large investments into nuclear energy could divert funds and focus away from renewable sources like solar and wind which are quickly achieving cost parity, often better matched to grid needs, and do not have the same economic, safety or waste risks as nuclear. A balanced approach is needed.
Domestic capacity: India's nuclear ambitions depend heavily on foreign reactor designs, fuel sources and technical cooperation, especially from Russia and France. This dependence could compromise India's aim for energy self-sufficiency and technology leadership. Investing in education and R&D is needed.
Recent technological developments have addressed some nuclear concerns, but not eliminated them entirely:
Safety: New reactor designs like advanced light water reactors and fast breeder reactors incorporate more passive safety features, lower meltdown risks and higher tolerance for human error or natural disasters. Ex: AP1000 reactors can withstand earthquakes, tsunamis and have a 72-hour backup system. However, severe accidents remain possible and the "fail-safe" nature of reactors is still debated. Strict regulatory oversight is still needed.
Proliferation: Technologies like laser enrichment reduce proliferation risks by making the enrichment process more difficult to replicate, while new fuel types like mixed oxide (MOX) fuel make plutonium more difficult to extract for weapons. However, determined groups could potentially overcome these barriers, indicating safeguards must still be actively pursued.
Costs: Standardized reactor designs, modular components, and improved construction techniques aim to reduce costs through replication and learning curve impacts. Ex: Modular reactors could cost 50-70% less. However, nuclear remains capital intensive, projects often run over-budget, and reliable cost reductions remain uncertain - especially where subsidies or public funds are used.
Waste: New reprocessing techniques can recycle used nuclear fuel and recover usable uranium and plutonium. The recycled fuel can power advanced reactors, minimizing waste. India uses a plutonium-uranium extraction process. However, reprocessing still results in radioactive byproducts that require storage. And it can increase proliferation risks which must be addressed.
Renewable integration: Nuclear technology startups are developing smaller, more flexible reactors to complement intermittent renewable sources, providing low-carbon baseload when needed. Ex: NuScale's small modular reactors can balance loads. However, variable renewable costs are rapidly declining as technologies and coupled with storage, could potentially reduce need for large baseload capacity from nuclear.
Domestic capacity: India has established domestic manufacturing capabilities for nuclear components like coolant pipes, centrifuges, and control mechanisms through partnerships between the NPCIL and private industry. India also has a well-developed nuclear fuel cycle, including facilities for mining, milling, conversion, enrichment, and fuel fabrication, as well as facilities for reprocessing spent nuclear fuel. India is also developing advanced nuclear technologies, such as fast breeder reactors and thorium-based reactors. However, India still imports key reactor components from Russia and France due to limited technical experience. Developing a robust domestic supply chain will take time.

India is also developing advanced nuclear technologies, such as fast breeder reactors and thorium-based reactors.
So nuclear technology offers promise but no panacea. Its viability, costs and necessity in any country's energy mix depends on a comparison to all available options - and selection of the optimal diverse, balanced and sustainable supply with fair consideration of risks and benefits. An open and honest appraisal is still most prudent with any pursuit of nuclear power.
Energy security: India has a severe energy deficit and high dependence on coal, with over 70% of electricity generated from coal. Nuclear power provides energy security by diversifying fuel sources for electricity and reducing overreliance on any single source. Ex: France derives over 70% of its electricity from nuclear, ensuring stable supply.
Energy poverty: Energy poverty is a major challenge in India, with millions of people lacking access to basic energy services. Nuclear power can help address this challenge by providing a reliable and affordable source of energy to remote and underserved areas.
Low-carbon source: Unlike coal, nuclear power does not emit greenhouse gases and particulate pollution. It can help India meet its climate change mitigation goals under the Paris Agreement as a low-carbon source for base load power. Ex: Sweden aims to phase out fossil fuels in favor of nuclear and renewable energy for a carbon-neutral grid.
Economic benefits: The nuclear power industry creates many jobs in research, reactors construction, and supporting sectors. Kudankulam nuclear plant in Tamil Nadu employs over 2000 people. Nuclear also reduces the need to import expensive fossil fuels. Operation of nuclear plants over 60-100 year lifetimes provide long-term economic value.
Energy independence: Domestically produced nuclear fuel reduces dependence on imported energy sources like coal, oil and natural gas - providing greater energy security and independence. India aims to develop its domestic uranium resources and thorium-based reactors. Ex: Canada's uranium mining industry employs over 60,000 people and sustains remote communities.
Reliable: Nuclear power plants operate at over 90% capacity for most of their lifetimes, providing a constant and stable source of baseload power to grids regardless of weather conditions or time of day. Ex: South Korea generates about 30% of its power from nuclear, operating at over 95% capacity.
Existing investments: India has invested heavily in nuclear energy, with 22 commercial reactors operating and 7 under construction. Kudankulam plant alone cost $6.7 billion. Scrapping nuclear prematurely would lead to loss of this investment and wasted capital that could have gained from the plants' operation over 60+ years.
Advanced technologies: New nuclear technologies can strengthen the case for nuclear in India, including more advanced light water reactors, fast breeder reactors, and thorium-based reactors which use domestically available fuel sources.
Technological penetration: Development of nuclear reactors can drive technological progress in India through several mechanisms:
Materials science: Nuclear reactors require advanced materials that can withstand high temperatures, pressures and radiation over long periods. Progress in materials like zirconium alloys, graphite, and new ceramics has applications in other industries like aerospace, defense, and electronics. India aims to develop silicon carbide composites for future reactors.
Manufacturing: High-precision manufacturing techniques are needed to produce nuclear reactor components. Electron beam welding, 3D printing processes etc require technical skills that translate to other sectors. India's Make in India initiative aims to localize nuclear supply chains to support manufacturing growth.
Robotics: Nuclear reactors utilize robotics for inspection, maintenance and handling of radioactive materials. Developments in robotics, sensors and remote tooling have spin-off benefits for fields like space exploration, mining, and hazardous waste management.
Sensors and monitoring: Nuclear reactors employ advanced sensors, detectors and real-time monitoring technologies to control processes, detect anomalies and prevent accidents. Technologies like optical spectroscopy, radiation mapping and ultrasonic transducers have medical, security and industrial applications.
Fusion: Research in nuclear fusion aims to develop clean, abundant energy by replicating the processes of the sun on earth. Fusion programs push boundaries in areas like advanced electromagnets, plasma physics and high-heat materials that ultimately benefit sectors like space travel, computing, and accelerator science. India operates an experimental tokamak fusion device.
Context : The Climate Ambition Summit (CAS) in New York, as part of the United Nations General Assembly, that concluded on September 21, was marked by the absence of major economies whose actions significantly influence the future of global emissions. China, United States and India — who collectively account for about 42% of global greenhouse gas emissions and are the top three emitters in that order — were all absent from the CAS.
What is Climate Ambition summit?
To accelerate action by governments, business, finance, local authorities and civil society, and hear from “first movers and doers,” the United Nations Secretary-General convened a Climate Ambition Summit at United Nations Headquarters in New York on 20 September 2023.
The Summit represents a critical political milestone for demonstrating that there is collective global will to accelerate the pace and scale of a just transition to a more equitable renewable-energy based, climate-resilient global economy.
The main goal is to keep the 1.5°C degree goal of the Paris Agreement alive and deliver climate justice to those on the front lines of the climate crisis.
In the run-up to the summit, about 100 heads of State had written to ramp up action to address the climate crisis. However, only representatives from 34 states and 7 institutions were given the floor on the day of the summit.
The criteria for countries to be considered for a speaking slot at the summit were:
That they would be expected to present updated pre-2030 Nationally Determined Contributions (as agreed in Glasgow);
Updated net-zero targets;
Energy transition plans with commitments to no new coal, oil and gas;
India’s climate commitments: India last updated its climate pledges in 2022 of reducing emissions intensity — or the volume of emissions per unit of gross domestic product (GDP) — by 45% from 2005 levels by 2030, a 10% increase from what it agreed to in 2015.
The government committed to meet 50% of its electric power needs from renewable, non-fossil fuel energy sources — up from 40% committed at the Paris agreement. It assured to create an additional carbon sink of 2.5 to 3bn tonnes of CO2-equivalent [GtCO2e] through additional forest and tree cover by 2030. In 2021, Prime Minister Narendra Modi committed to India achieving net zero by 2070.
The scientific assessment is that India’s commitment, alongside similar commitment by G-20 economies are insufficient to keep temperatures from keeping below 2C by the end of the century. However, India’s low per capita emissions and contribution to the carbon already in the atmosphere has led other analysts to suggest that India has committed to “more than its fair share” to keeping to the Paris-agreed limits.
Context: India’s economy is expected to face constraints in FY 2023-24, with weak global demand and monetary policy tightening to manage inflationary pressures. Reasons for which include:
Challenges to Indian Economic Growth
Erratic Weather Patterns: Monsoon rainfall under the influence of a developing El Niño has led to erratic weather patterns, including flooding in certain regions and deficient rains, particularly in August. The erratic rainfall patterns have resulted in damage to the rice crop in particular and lower sowing for pulses in the kharif season.
High Inflation & Moderating Demand: The economy has been impacted by moderating demand and high inflation, leading to a slowdown in economic activity.
Inflation, especially for energy and food, has reduced purchasing power and household consumption, particularly in urban areas.
Declining Investment: Weakening credit-supported demand for capital goods indicates a decline in business investment.
Trade Deficit in Goods: While services exports have shown growth, it is insufficient to offset the trade imbalance in goods.
Low labour productivity is affecting the competitiveness of Indian goods and participation in global value chains.
Other Challenges: Challenges include potential deterioration of banks’ asset quality, delays in fiscal consolidation, difficulties in trade agreements, and the impact of below-normal monsoon seasons.
What is the Asian Development Bank (ADB)?
The Asian Development Bank's primary mission is to "foster economic growth and cooperation" among countries in the Asia-Pacific Region.
Headquarters: Manilla, Philippines.
Structure:
The Agreement Establishing the Asian Development Bank, known as the ADB Charter, vests all the powers of the institution in the Board of Governors, which in turn delegates some of these powers to the Board of Directors.
The ADB's highest policy-making body is its Board of Governors, which comprises one representative from each member.
The Board of Governors meets formally once a year during ADB's Annual Meeting.
Membership:
It is open to members and associate members of the United Nations Economic Commission for Asia and the Far East.
It's also open to other regional countries and non-regional developed countries that are members of the U.N. or of any of its specialised agencies.
At present, there are a total of 68 members, which is made up of 48 regional and 19 non-regional members.
Although the majority of the Bank's members are from the Asia-Pacific region, the industrialised nations are also well-represented.
ADB's five largest shareholders are Japan and the United States (each with 15.6% of total shares), the People's Republic of China (6.4%), India (6.3%), and Australia (5.8%).
Source of Capital:
The ADB raises capital regularly through the international bond markets.
The ADB also relies on member contributions, retained earnings from lending, and the repayment of loans for the funding of the organisation.
Functions:
The Asian Development Bank provides assistance to its developing member countries, the private sector, and public-private partnerships through grants, loans, technical assistance, and equity investments to promote social and economic development.
The ADB regularly facilitates policy dialogues and provides advisory services. They also use co-financing operations that tap official, commercial, and export credit sources while providing assistance.
Nature of Financing:
The ADB provides both private financing and sovereign (public) financing.
Private sector efforts focus on projects that help promote private investments in the region that will have significant development impact and will lead to accelerated, sustainable, and inclusive growth.
Public-sector financing provides funding for member countries with flexibility in determining how they can achieve development goals.
