White Rhino Resurrection IVF Project
- Project: BioRescue, a team of scientists from around the world, embarked on a mission to revive the northern white rhino through IVF in 2015.
- Historic Breakthrough: In a remarkable achievement, scientists announced the first-ever rhino pregnancy via the transfer of a lab-made rhino embryo into a surrogate mother.
- Persistence and Dedication: The breakthrough with a southern white rhino, a close relative, followed 13 attempts, showcasing the dedication of the scientists.
Challenges on Road to Revival
- Unique Challenge: Northern white rhinos face an unusual predicament due to the infertility of the last two surviving females, Najin and Fatu.
- Surrogacy Complexity: Preparing a southern white female as a surrogate mother involves isolation, infection prevention protocols, and precise identification of the fertile window.
- Genetic Viability: Even with successful IVF and surrogacy, the limited gene pool from eggs and sperm of deceased zoo rhinos poses a challenge.
- Stem Cell Possibilities: Exploring stem cell techniques to broaden the gene pool shows promise but is experimental and challenging to implement in rhinos.
Lessons from Conservation
- Wild Resilience: Conservation efforts saved the southern white rhino from near-extinction, with their numbers rebounding from a mere 20 in the 19th century to over 17,000.
- Crossbreeding Dilemma: Crossbreeding northern and southern subspecies is not a viable solution due to the loss of unique attributes.
- Behavioral Legacy: Restoring a species requires more than genetic revival; it necessitates the transmission of behavioral traits learned from adults of the same species.
The Race against Time
- Critical Window: To preserve the northern white rhino’s unique behavioral traits, the first IVF calves must learn from the last two surviving females, Najin and Fatu.
- Looming Deadline: With Najin at 35 and Fatu at 24, the window for this crucial interaction is closing, as northern white rhinos rarely live beyond 40 in captivity.
- A Costly Endeavor: BioRescue, funded by the German government and donors, has invested millions in this project, raising questions about resource allocation and prioritization.
The Bigger Picture
- A Noble Cause: The effort to revive the northern white rhino stems from a sense of responsibility to counteract human-driven extinction.

From UPSC perspective, the following things are important :
Prelims level: Neutron Stars
Mains level: Read the attached story

Introduction
- In the field of astronomy, astronomers sometimes stumble upon celestial objects that leave them scratching their heads.
- In a recent study published in Science, a discovery was reported that is likely to get scientists talking and asking questions.
Neutron Stars: Exceptionally Dense
- Incredibly Dense Objects: Neutron stars are some of the densest things in the universe. They’re as compact as an atomic nucleus but as big as a city, pushing our understanding of super-dense matter to the limit.
- A Weighty Matter: The heavier a neutron star is, the more likely it is to eventually collapse and become something even denser, like a black hole.
Puzzling the Boundary
- A Cosmic Mystery: To understand what happens when neutron stars turn into black holes, objects that are in-between need to be found. These objects also need to be studied very carefully over a long time.
- A New Discovery: A cosmic system has been found in the NGC 1851 star cluster that doesn’t fit neatly into the categories of neutron stars or black holes.
NGC 1851E: The Revelation
- Seeing Something New: Inside NGC 1851, a pair of stars has been spotted that provides fresh insights into the extreme matter in the universe. This system has a millisecond pulsar, a fast-spinning neutron star that sends out beams of radio light, and a massive, dark companion that can’t be seen at any wavelength of light.
- The Pulsar’s Role: Millisecond pulsars are like cosmic clocks. They spin steadily, and any changes in their spin can tell important things about what’s around them.
Unveiling the Weight of Secrets
- Very Precise Measurements: The MeerKAT radio telescope in South Africa was used to closely watch the NGC 1851E system.
- What Was Found: Observations allowed figuring out exactly how the two objects move around each other and how heavy they are together. The system’s mass is almost four times that of the Sun, and the invisible companion is denser than a regular star but not as heavy as a black hole.
- A Strange Mass Gap: The companion’s mass falls in a range that’s puzzling to scientists, between the heaviest neutron stars and the lightest black holes. Understanding objects in this range is a big mystery in astrophysics.
A Stellar Dance: Cosmic Partnerships
- A Fascinating Idea: One intriguing possibility is that a pulsar is circling around what’s left after two neutron stars collided, something made possible because there are many stars packed closely together in NGC 1851.
- Starry Dance Floor: In this crowded group of stars, they twirl around each other, changing partners as they go. If two neutron stars get too close, they collide, creating a black hole. This black hole can then disturb the dance of other stars in the cluster.
- Still Many Questions: The work isn’t finished. Research is continuing to figure out exactly what the companion is. Is it the lightest black hole, the heaviest neutron star, or something completely different?
- Exploring New Frontiers: When at the border between neutron stars and black holes, there’s a chance of discovering completely new types of objects.

Prelims level: Deep Learning in Antibiotic Discovery
Mains level: Read the attached story
Introduction
- The year 1944 witnessed the simultaneous emergence of artificial neural networks, laying the foundation for deep learning, and the discovery of streptomycin, the first aminoglycoside antibiotic.
- This historical synchrony ultimately connects deep learning and antibiotics.
Why in news?
- In December 2023, scientists introduced a groundbreaking alliance between deep learning and antibiotics by leveraging deep learning techniques to discover a new class of antibiotics, addressing a multi-decade gap in antibiotic development.
Deep Learning in Antibiotic Discovery
- Different Approach: Unlike previous applications of deep learning in drug discovery, this study focused on identifying chemical motifs or substructures used by the deep learning model to evaluate compounds for antibiotic potential, rendering the model “explainable”.
- Proven Efficacy: The research successfully demonstrated the effectiveness of two compounds from the newfound antibiotic class against methicillin-resistant Staphylococcus aureus (MRSA) infections, a major cause of human fatalities in 2019.
- Recognition and Expansion: Experts praised the study for its contributions to antibiotic research and its potential to enhance drug development strategies.
Understanding Deep Learning and Explainability
- Neural Networks: Deep learning relies on artificial neural networks, comprising layers of artificial “neurons” that process inputs and yield outputs through training and testing phases.
- Training and Testing: Deep learning networks are trained on large datasets with annotated inputs to learn specific tasks. During testing, they classify novel inputs based on their learned knowledge.
- The Black Box Issue: Most deep learning models lack transparency in explaining how they arrive at their conclusions, remaining “black boxes.”
- Explainable Deep Learning: In contrast, the study’s model was designed to be explainable, allowing it to not only predict antibiotic potential but also elucidate the substructures contributing to this property.
Journey to Novel Antibiotics
- Experimental Screening: The research began by screening over 39,000 compounds to inhibit S. aureus growth, shortlisting 512 active compounds.
- Graph Neural Network (GNN): A GNN was trained on the dataset, representing atoms as nodes and bonds as edges on a mathematical graph.
- Selecting Non-Toxic Compounds: To ensure safety, 306 compounds were identified that didn’t harm human cells, and other GNNs were trained to identify cytotoxic compounds.
- Identifying Potential Antibiotics: The GNNs evaluated a database of over 1.2 crore compounds, identifying 3,646 potential antibiotics based on substructures.
- Substructure Rationales: The study introduced “rationales” to explain the substructures that conferred antibiotic properties to molecules.
- Efficacy Against MRSA and VRE: Certain compounds, including N-[2-(2-chlorophenoxy)ethyl]aniline, exhibited inhibition of MRSA and vancomycin-resistant enterococci (VRE).
- Mouse Models: One compound effectively reduced MRSA-related skin and thigh infections in mouse models.
Significance and Ongoing Challenges
- Transparency in Drug Discovery: The study’s significance lies in rendering deep learning approaches to drug discovery more transparent and reproducible across drug categories.
- Future Exploration: Researchers are applying substructure rationales to design new antibiotics and explore applications in drugs targeting age-related disorders.
- Addressing a Lacuna: An identified shortcoming is that explainability analysis occurred after predicting antibiotic properties. Implicitly incorporating explainability in deep learning models is proposed as a more robust approach.

- Objective: The primary objective is to facilitate citizenship for non-Muslim immigrants from India’s three Muslim-majority neighboring countries.
- Residence Requirement: The Citizenship Act, 1955, normally requires 11 of the previous 14 years of residence in India as a condition for naturalization.
- Amendment: CAA reduces this requirement to 6 years for applicants belonging to the specified religions and countries.
- Exemption from Criminal Cases: Members of the designated communities are exempted from criminal cases under the Foreigners Act, 1946, and the Passport Act, 1920, if they entered India before December 31, 2014.
Defining Illegal Migrants
- Status Under Present Laws: Existing laws prohibit illegal migrants from acquiring Indian citizenship.
- CAA’s Definition: CAA classifies an illegal migrant as a foreigner who enters India without valid travel documents (passport and visa) or overstays beyond the allowed period.
- Penalties: Illegal migrants can face imprisonment or deportation under the Foreigners Act, 1946, and The Passport (Entry into India) Act, 1920.
Exceptions under CAA
- Conditions for Exemption: CAA outlines four conditions that, if met, exempt certain individuals from being treated as illegal migrants:
- They belong to the specified religions (Hindu, Sikh, Buddhist, Jain, Parsi, or Christian).
- They hail from Afghanistan, Bangladesh, or Pakistan.
- They entered India on or before December 31, 2014.
- They are not in certain tribal areas of Assam, Meghalaya, Mizoram, or Tripura (Sixth Schedule) or “Inner Line” permit areas (Arunachal Pradesh, Mizoram, and Nagaland).
Controversies Surrounding CAA
- Country of Origin: CAA categorizes migrants based on their country of origin, specifically Afghanistan, Pakistan, and Bangladesh.
- Religious Exclusivity: It raises questions about why only six specified religious minorities have been considered in the Act.
- Omission of Rohingya: The Act doesn’t address the Rohingya Muslims from Myanmar, who have faced persecution.
- Entry Date Differentiation: The differential treatment of migrants based on their entry date, i.e., before or after December 31, 2014, has generated debate.
- Secularism Concerns: Critics argue that granting citizenship based on religion contradicts the secular principles of India’s Constitution, considered part of the unalterable basic structure.

From UPSC perspective, the following things are important :
Prelims level: Sovereign 'Guarantee'
Mains level: Not Much
Introduction
- A working group constituted by the Reserve Bank of India (RBI) has presented key recommendations to address challenges related to guarantees extended by State governments.
Understanding ‘Guarantee’
- A ‘guarantee’ involves a legal obligation for a State to make payments on behalf of a borrower, safeguarding investors/lenders from default risks.
- As defined by the Indian Contracts Act (1872), it is a contract involving three parties: the principal debtor, creditor, and surety (State government).
- The ‘guarantee’ acts as a safety net, ensuring payment in case of default by the borrower.
Purpose of ‘Guarantee’ at the State Level
- Sovereign Guarantee: Facilitates concessional loans from bilateral or multilateral agencies to public sector enterprises.
- Project Viability: Enhances project viability for activities with significant social and economic benefits.
- Resource Mobilization: Enables public sector enterprises to secure resources at favorable terms, contributing to lower interest charges.
Fiscal Risks and Working Group Recommendations
- Cash Outflows and Debt: While guarantees may not require upfront cash payments, they pose fiscal risks, leading to unanticipated cash outflows and increased debt during challenging times.
- Complex Estimation: Estimating the quantum and timing of potential costs/cash outflows is challenging due to triggers associated with guarantees.
Recommendations on ‘Guarantee’ Definition and Guidelines
- Broadened Definition: The term ‘guarantee’ should encompass all instruments creating obligations for the guarantor (State) to make future payments on behalf of the borrower.
- Guidelines for Accordance: Government guarantees should not substitute budgetary resources and should adhere to Government of India guidelines.
- Preconditions: Specify preconditions, including the period of guarantee, guarantee fee, government representation on the management board, and audit rights.
Risk Determination, Fee, and Ceiling
- Risk Weight Assignment: States should assign risk weights (high, medium, low) before extending guarantees, considering past defaults.
- Ceiling on Guarantees: A desirable ceiling for incremental guarantees during a year, limiting stress on state governments.
- Guarantee Fee Structure: Reflective of borrower’s project riskiness and activities, with a base fee of at least 2.5% per annum.
Disclosures and Honouring Commitments
- Credit Disclosure: Banks/NBFCs should disclose credit extended to State-owned entities backed by State guarantees for improved credibility.
- Database Establishment: Set up a state-level unit to track and consolidate all guarantees, ensuring proper data compilation.
- Timely Honouring: States must honor guarantees without delay, recognizing the reputational and legal risks associated with defaults.
Conclusion
- The RBI working group’s recommendations aim to fortify fiscal management by introducing standardized practices, enhancing risk assessment, and ensuring transparent disclosures.
- These measures, if implemented, can contribute to better fiscal discipline and mitigate potential risks associated with state government guarantees.

From UPSC perspective, the following things are important :
Prelims level: Encryption
Mains level: Not Much

Introduction
- In today’s digital age, information is invaluable, and encryption serves as a crucial means to protect it.
- Specifically, end-to-end (E2E) encryption has transformed how human rights organizations, law enforcement, and technology companies handle sensitive information.
What is Encryption?
- Encryption Definition: Encryption involves transforming consumable information into an unconsumable form based on specific rules. Different encryption methods exist, providing varying levels of security.
- Example of DES: The Data Encryption Standard (DES) encrypts text like “ice cream” to a garbled form with a specified key, such as “kite” or “motorcycle.”
- Key Importance: A key serves as the means to unlock (decrypt) encrypted text, ensuring that only authorized individuals can access the original information.
What is End-to-End Encryption (E2E)?
- E2E Encryption Defined: E2E encryption focuses on specific locations through which information travels. In a messaging app, for instance, E2E encryption ensures that messages are encrypted both during transmission and storage, only decrypted when received by the intended recipient.
- Protection in Transit and at Rest: E2E encryption safeguards information during transmission and while stored on servers, providing comprehensive protection.
Mechanisms of Information Encryption
(A) Symmetric vs. Asymmetric Encryption:
- Symmetric Encryption: The same key is used for both encryption and decryption. Examples include DES and Advanced Encryption Standard (AES).
- Asymmetric Encryption: Different keys are used for encryption and decryption. Public and private key pairs, such as Curve25519, exemplify asymmetric encryption.
(B) Hash Functions:
- Hash Function Properties: Hash functions encrypt messages with properties like non-reversibility, fixed-length output, and uniqueness for unique inputs.
- Example of DES Hash Function: DES uses a complex process, including S-boxes, to encrypt messages.
Can E2E Encryption Be ‘Cracked’?
- MITM Attacks: A man-in-the-middle (MITM) attack involves intercepting messages by acquiring encryption keys. Countermeasures include fingerprint comparison to detect tampering.
- Complacency Risks: Users may become complacent, assuming total security. However, malware and backdoors can compromise device security, allowing unauthorized access.
- Metadata Surveillance: While E2E encryption secures message content, surveillance can occur through metadata analysis, revealing information about message timing, recipients, and locations.
- Backdoor Risks: Companies implementing E2E encryption may install backdoors, enabling access for legal or illicit purposes. Examples, like the Snowden affair, highlight potential misuse.

From UPSC perspective, the following things are important :
Prelims level: Radioactive wastes mentioned
Mains level: Nuclear Pollution

Introduction
- A recent study conducted by researchers at the Bhabha Atomic Research Centre (BARC), Mumbai, analyzed 20 years of radiological data (2000-2020) from six nuclear power plants in India.
- The findings highlight the minimal impact of radioactive discharges from these plants on the environment.
- The study aims to reinforce India’s commitment to its nuclear power program, challenging unfounded beliefs and influencing public and policy perspectives.
Radiological Analysis and Plant Selection
- Twenty-Year Data: The analysis covered radiological data from 2000 to 2020 from seven nuclear power plants.
- Focus on Fission Products: The study focused on concentrations of fission products and neutron-activated nuclides within a 5 km radius of each nuclear plant, considering samples collected up to a maximum radius of 30 km.
Gaseous and Liquid Discharges
- Components of Gaseous Waste: The gaseous waste released into the atmosphere included fission product noble gases, Argon-41, radioiodine, and particulate radionuclides (cobalt-60, strontium-90, caesium-137, and tritium).
- Liquid Discharge Components: Liquid discharge consisted of fission product radionuclides (radioiodine, tritium, strontium-90, caesium-137) and activation products like cobalt-60.
- Strict Regulatory Compliance: The discharges underwent dilution and dispersion, adhering to strict radiological and environmental regulatory regimes.
Radiological Measurements and Concentrations
- Air Particulates: Average gross alpha activity in air particulates across all seven nuclear plants remained below 0.1 megabecquerel (mBq) per cubic meter.
- Specific Markers: Concentrations of iodine-131, caesium-137, and strontium-90 in air particulates were below 1 mBq per cubic meter for iodine-131, with caesium-137 and strontium-90 concentrations three orders lower and below 10 microbecquerel per cubic meter.
Water Bodies and Sediments
- Rivers, Lakes, and Sea Water: Caesium-137 and strontium-90 concentrations in rivers and lakes were below 5 mBq per liter, and sea water near the nuclear plants registered less than 50 megabecquerel per liter.
- Sediment Analysis: Sediment analysis revealed that caesium-137 concentration was highest at the Rajasthan Atomic Power Station, while strontium-90 concentration peaked at the Narora Atomic Power Station.
Tritium Detection and Total Doses
- Tritium Presence: Tritium was detectable at all sites except the Kudankulam Nuclear Power Station, where it was not detected during the study period.
- Total Doses: Though total doses remained below regulatory limits, Rajasthan, Madras, and Tarapur power plants showed relatively higher total doses. Efforts are being made to further limit doses at these sites to keep them as low as reasonably achievable (ALARA).
Conclusion
- The BARC study’s comprehensive analysis concludes that the environmental impact of Indian nuclear power plants, based on 20 years of radiological data, has been minimal.
- The findings not only emphasize the safe operation of these plants but also contribute to dispelling unwarranted beliefs, supporting India’s commitment to advancing its nuclear power program.
- The study’s insights are poised to shape public and policy perspectives on nuclear energy in the country.

Introduction
- On January 26, India celebrates Republic Day, marking the day when its Constitution came into effect in 1950.
- However, the roots of this celebration trace back to January 26, 1930, when India made the historic “Poorna Swaraj” declaration, signifying its quest for complete independence from British rule.
Context of the 1920s
- Non-Cooperation Movement: The 1920s witnessed the aftermath of the Non Cooperation Movement and the Chauri Chaura incident, which prompted Mahatma Gandhi to temporarily halt non-violent protests.
- Rise of Leaders: This period saw the emergence of notable leaders like Bhagat Singh, Chandrashekhar Azad, Jawaharlal Nehru, Subhash Chandra Bose, Vallabhai Patel, and C. Rajagopalachari, setting the stage for India’s future freedom struggle.
Simon Commission and Nehru Report
- Simon Commission: In 1927, British authorities appointed the Simon Commission to discuss political reforms in India, sparking nationwide protests with slogans like “Simon Go Back.”
- Nehru Report: In response, the Indian National Congress (INC) established its own commission under Motilal Nehru, advocating dominion status for India within the British Empire.
Internal Disagreements: Dominion or Republic?
- Dominion Status Debate: While the Nehru Report called for dominion status, leaders like Subhash Chandra Bose and Jawaharlal Nehru favored complete independence, fearing that dominion status would align India with colonial exploitation in the British Empire.
- Change in Gandhi’s Views: Initially supporting dominion status, Mahatma Gandhi’s stance evolved as he began advocating for complete independence.
Irwin Declaration and Backtracking
- Irwin Declaration: In 1929, Viceroy Irwin vaguely promised dominion status for India, which sparked hope among Indians but faced opposition in Britain.
- Backtracking: Under pressure from Britain, Irwin retracted his promise during a meeting with Indian leaders, leading to growing unity within the INC for complete independence.
Declaration of Poorna Swaraj
- Lahore Session of INC: In December 1929, during the Lahore Session of the INC, the “Poorna Swaraj” resolution was passed, calling for complete independence from British rule.
- Official Promulgation: On January 26, 1930, this declaration of independence was officially announced, marking a pivotal moment in India’s freedom struggle.
- Nonviolent Protest: The resolution also affirmed the Gandhian principles of nonviolent protest, which became integral to the subsequent struggle for independence.
Republic Day in Post-Independence India
- Celebrating Independence: From 1930 until India’s independence in 1947, January 26 was celebrated as “Independence Day” or “Poorna Swaraj Day,” symbolizing India’s commitment to sovereignty.
- Constitution Adoption: When India adopted its Constitution, leaders chose January 26 for Republic Day, as it held historical significance and aligned with the ideals of complete independence as articulated in the “Poorna Swaraj” declaration.
- Symbolism: Today, Republic Day commemorates India’s journey to self-rule and reflects the principles enshrined in its Constitution.
