Earth’s Inner Core Rotation Slowing Down
Tags: GS-1, Geography – Earth- Core
Why in the news?
- Recently, new study has provided compelling evidence that the Earth’s solid inner core, composed of iron and nickel, began to slow down its rotation compared to the planet’s surface in 2010.
- Since the Earth’s core and most part of the Earth’s interior is physically inaccessible, researchers typically study it by analysing seismic waves generated by earthquakes recorded on seismograms.
Impacts:
- The process could potentially change the length of a day on Earth by fractions of a second.
- The inner core‘s spin is influenced by the magnetic field generated in the liquid outer core and gravitational effects within the Earth’s mantle.
- The inner core’s rotation generates Earth’s magnetic field and influences geological processes. Changes in its rotational speed could affect Earth’s magnetic properties and geomagnetic events.
- The recent study says that the inner core is reversing and backtracking relative to the surface, rotating slower than the mantle for the first time in about 40 years.
Connection to Climate Change and Earth’s Rotation:
- A separate study (Nature Journal) found that climate change-driven melting of ice in Greenland and Antarctica was affecting global timekeeping by slowing down Earth’s rotation.
- The liquid core was slowing down, causing the solid Earth to rotate faster to counterbalance the effect, resulting in fewer ‘leap seconds’ being needed to be added to the Coordinated Universal Time (UTC).
| Since 1972, a ‘leap second’ has been periodically added to the UTC to account for irregularities in Earth’s rotation speed. |
Coordinated Universal Time (UTC):
- UTC is the primary time standard by which the world regulates clocks and time. It is based on precise atomic clocks and is maintained by the International Bureau of Weights and Measures (BIPM).
- UTC is designed to approximate the mean solar time at 0° longitude (the prime meridian), which is the basis for civil time and time zones.
Leap Seconds:
- The Earth’s rotation is gradually slowing due to tidal forces from the Moon and Sun, as well as changes in Earth’s structure and climate. Consequently, the length of a day based on Earth’s rotation increasingly diverges from the day defined by atomic clocks.
- To account for this divergence and keep UTC in sync with the Earth’s rotation, leap seconds are added.
- A leap second is a one-second adjustment that is inserted as a “stop” second into UTC to keep it aligned with the Earth’s rotation. It is added on either June 30th or December 31st, as required.

CRISPR Cas9 Gene Therapy for Sickle Cell Disease
Tags: GS-3 , Sc. & Tech.-Awareness in various sc and tech fields
Why in the News?
- Recently, India is advancing towards the development of a CRISPR-Cas9-based gene therapy for sickle cell disease (SCD), a genetic blood disorder highly prevalent among Scheduled Tribes.
What is Sickle Cell Disease?
- Sickle cell disease (SCD) is a group of inherited blood disorders caused by a genetic mutation in the hemoglobin-β gene located on chromosome 11, resulting in defective haemoglobin that forms rod-like structures after releasing oxygen.
- This mutation leads to red blood cells becoming rigid and assuming a sickle shape.
- SCD is inherited in an autosomal recessive pattern, requiring both parents to carry the abnormal gene for a child to inherit it.
- Symptoms may not manifest immediately in newborns but can include extreme tiredness, fussiness, swollen hands and feet, and jaundice.
Implications:
- The misshapen red blood cells can block small blood vessels, impairing blood flow and causing chronic anaemia.
- Individuals with SCD often suffer acute pain episodes, severe bacterial infections, and tissue damage due to insufficient blood supply.
Treatment:
- Current treatment options include medications for pain relief and regular blood transfusions to replace damaged red blood cells.
- In rare cases, a bone marrow or stem cell transplant, which carries significant risks, may be recommended.
Eliminating Sickle Cell Disease:
- Recent advancements include the U.S. Food and Drug Administration’s approval of CRISPR-Cas9 technology for cell-based gene therapy to treat sickle cell disease in December 2023.
- India faces the primary challenge of developing cost-effective therapy as part of its mission to eradicate sickle cell disease by 2047, initiated by the Prime Minister in July 2023.
- The mission targets conducting over 7 crore screenings among vulnerable tribal populations across 17 States and Union Territories, with three crore screenings completed to date.
CRISPR-Cas9 Gene Editing:
- CRISPR-Cas9, short for Clustered Regularly Interspaced Short Palindromic Repeats and CRISPR-associated protein 9, is a powerful technology enabling geneticists and researchers to edit sections of the genome by modifying DNA sequences.
- Emmanuelle Charpentier and Jennifer Doudna’s pioneering work on CRISPR-Cas9, likened to a ‘molecular scissor,’ earned them the 2020 Nobel Prize in chemistry.
The system comprises two primary components:
- Cas9: This enzyme functions as molecular scissors, cutting the DNA strand at a precise location targeted for modification, such as removal, addition, or alteration of DNA.
- Guide RNA (gRNA): This RNA segment is designed to bind to a specific DNA sequence complementary to its code. The gRNA directs the Cas9 enzyme to the exact location in the genome where genetic editing is intended.
Mechanism:
- Initially, a gRNA is designed to match the DNA sequence requiring modification.
- Once inside the cell, the Cas9 enzyme and gRNA form a complex that locates and binds to the targeted DNA sequence.
- Cas9 then cleaves the DNA at the predetermined site.
- Following the DNA cut, the cell’s natural repair mechanisms can be utilised to insert or delete genetic material, or to make precise alterations to the DNA sequence

Persistent Organic Pollutants (POPs)
Tags: GS –3 , Ecology & Environment— Environmental Pollution–(POPs)
Why in the news?
- According to a recent study, Dichloro-diphenyl-trichloroethane (DDT) and 11 other Persistent Organic Pollutants (POPs) have shown a decline in both human exposure and environmental presence since 2004.
- This reduction is attributed to stringent global regulations implemented to control these hazardous substances.
What about Persistent Organic Pollutants (POPs)?
- Findings from the study indicate that Persistent Organic Pollutants (POPs), including DDT and others, were detected in over 900 samples collected from various sources such as air, water, human milk, soil, and various food items including beef, milk, eggs, and seafood.
- The levels of 12 POPs, including DDT, have shown a global decline since 2004, attributed to stringent regulatory measures.
- However, other POPs like dieldrin and polychlorinated biphenyls (PCBs) continue to persist at elevated levels in the air across regions such as Africa, the Caribbean, and Latin America.
- POPs are carbon-based chemicals that resist degradation through natural processes like chemical reactions, biological breakdown, and sunlight exposure.
Key characteristics of Persistent Organic Pollutants (POPs):
- Persistence: POPs are resistant to environmental breakdown. They can persist for extended periods, ranging from years to decades, without degrading.
- Bioaccumulation: POPs have the tendency to accumulate in the fatty tissues of living organisms through the food chain. This results in higher concentrations of POPs in organisms at the top of the food chain, including humans.
- Long-range transport: POPs can travel long distances from their original source of emission. Global transport occurs through processes such as atmospheric deposition and ocean currents, spreading these pollutants across vast distances.
- Toxicity: Many POPs exhibit toxicity to both humans and wildlife. They can lead to various adverse health effects, including cancer, reproductive disorders, immune system disruption, and neurological impacts.
- POPs include pesticides like DDT (dichloro-diphenyl-trichloroethane), industrial chemicals such as polychlorinated biphenyls (PCBs), and unintentional by-products of industrial processes like dioxins and furans.
- POP pollution include improper use or disposal of agrochemicals and industrial chemicals, high-temperature processes and combustion, and unintentional production during industrial activities or waste incineration.
Regulation of Persistent Organic Pollutants (POPs) :
- Stockholm Convention on POPs: Entered into force in 2004, it aims to globally reduce the release of POPs chemicals.
- Rotterdam Convention on PIC: Also entered into force in 2004, it promotes shared responsibilities in the international trade of hazardous chemicals, ensuring safe use.
- Basel Convention: In force since 1992, it controls transboundary movements and disposal of hazardous wastes to protect human health and the environment.
- LRTAP, Protocol on POPs: The protocol, effective since 2003, aims to limit and reduce air pollution, including long-range transboundary air pollutants like POPs. Its goal is to control, reduce, or eliminate discharges, emissions, and losses of persistent organic pollutants.

Challenges in Nuclear Disarmament
- Geopolitical Tensions: Nations often view nuclear weapons as a deterrent against potential adversaries, which hinders willingness to disarm when perceived threats exist.
- Transparency: Verifying compliance with disarmament agreements is challenging, complicating efforts to ensure adherence to agreed-upon reductions.
- Technological Advancements: Advances in nuclear technology, such as smaller and more sophisticated weapons, pose obstacles to effective disarmament initiatives.
- Strategic Stability Concerns: Countries may see nuclear weapons as vital to national security, fearing that disarmament could disrupt strategic stability and deter them from fully committing to disarmament efforts.
- Economic and Strategic Costs: The process of dismantling nuclear weapons and managing their materials is costly and complex, presenting financial and logistical challenges.
- Non-Proliferation Concerns: As some states disarm, others may perceive a strategic advantage in acquiring or retaining nuclear weapons, potentially sparking proliferation concerns and undermining disarmament goals.
Treaties Related to Nuclear Disarmament:
- Treaty on the Non-Proliferation of Nuclear Weapons (NPT):
- Signed in 1968 and effective from 1970, the NPT aims to prevent nuclear weapon proliferation and encourage disarmament.
- It categorises states as nuclear-weapon states (NWS), recognized for possessing nuclear weapons before the treaty, and non-nuclear-weapon states (NNWS), which commit to refraining from nuclear weapons development.
- Treaty on the Prohibition of Nuclear Weapons (TPNW):
- Adopted by the UN in 2017 and open for signature since 2018, the TPNW aims to ban the development, testing, production, stockpiling, stationing, transfer, use, and threat of use of nuclear weapons.
- It marks a significant step towards global nuclear disarmament, although nuclear-armed states have not signed it.
- Comprehensive Nuclear-Test-Ban Treaty (CTBT):
- Opened for signature in 1996, the CTBT seeks to prohibit all nuclear explosions, whether for civilian or military purposes.
- Despite being signed by 185 countries and ratified by 170, its entry into force requires ratification by nuclear-armed states.
- Outer Space Treaty:
- Entered into force in 1967, this agreement prohibits the placement of weapons of mass destruction in space.
- All nine known nuclear-armed states are parties to this treaty, contributing to the prevention of weaponization of outer space.

Eucalyptus Tree
Tags: GS-3 Ecology & Environment — Biodiversity- Species
Why in the news?
- The Kerala government issued an order allowing the Kerala Forest Development Corporation (KFDC) to plant eucalyptus trees for its financial sustenance in 2024-2025.
- As per the 2021 Kerala’s eco-restoration policy, its cultivation (including acacia and wattle) is not suitable for the environment as it results in “depletion of natural forests.”
- Activists alleged that permitting the planting of eucalyptus trees contravened the policy’s aspirations and undermined efforts to beat back invasive species and mitigate human-animal conflicts.
About Eucalyptus tree
- Eucalyptus trees, also known as gum trees, nilgiri trees, or safeda, are species of large flowering trees and shrubs with aromatic leaves and attractive smooth peeling bark.
- These trees are native to Australia and Tasmania. In India, it was first planted around 1790 by the ruler of Mysore, Tipu Sultan, in his palace garden near Bangalore.
Uses of eucalyptus trees
- Eucalyptus wood is hard and difficult to bend, making it ideal for flat furniture.
- Since the wood is heavy, it is, therefore, good as firewood and for making charcoal.
Criticism of Eucalyptus
- The ban on eucalyptus has emerged as part of the campaign against invasive species.
- Eucalyptus is water-intensive and reduces available water for other species by effectively out-competing them.
- In arid areas, it consequently suppresses different plant life, coupled with high water demand, reduces soil moisture, prevents groundwater recharge, and can reduce local water tables. This is worsened by a high transpiration rate indicative of the inefficient use of water.
- Eucalyptus does not promote the building of humus. It does not contribute to the soil’s long-term fertility resulting in an overall nutrient impoverishment of the soil.
- Eucalyptus is toxic due to its allelopathic properties, which reduce other plant life by restricting germination of other species and is also detrimental to soil micro and macrofauna.
| Allelopathic species suppress their progeny and other plant life by leaching chemical inhibitors from the trees’ roots or litter. |
