  • Wildlife Conservation Efforts

    Northern White Rhino IVF Project by BioRescue

    Prelims Only | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

    Northern White Rhino

    Introduction

    • The northern white rhino, once on the brink of extinction, saw its last male member pass away in 2018, leaving the subspecies on the verge of being lost forever.
    • However, a pioneering initiative was launched in 2015 by a group of international scientists known as BioRescue, to resurrect the northern white rhino through in vitro fertilisation (IVF).

    About Northern White Rhino

    Details
    Scientific Name Ceratotherium simum cottoni
    Geographic Range Eastern and Central Africa
    Population Status Critically Endangered (Only 2 individuals alive) in 2024
    Physical Characteristics Grayish-white color, two horns, hump on the neck
    Social Behavior Solitary, occasionally seen in small groups
    Diet Herbivorous, primarily grazers
    Conservation Efforts Extensive efforts to save from extinction
    IUCN Red List Status Critically Endangered

    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.
    • Conservation Imperative: While the project is ambitious, critics raise concerns about neglecting other endangered species and the need to protect natural habitats.
    • Broader Crisis: Rhino populations across species face grave threats, including poaching, with one rhino poached every 16 hours in Africa.

  • Gravitational Wave Observations

    Astronomers spot Unusual Object falling in Black Hole ‘Mass Gap’

    Prelims Only | Science Tech | Mains Paper 3: Awareness in various sc and tech fields

    Black Hole ‘Mass Gap’

    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.

    Deep Learning and Antibiotics Discovery

    Prelims Only | Science Tech | Mains Paper 3: Awareness in various sc and tech fields

    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.
