{GS1 – IS – Population} UN World Population Prospects Report

• Context (DTE): The UN Population Division of the UN Department of Economic and Social Affairs (UN-DESA) has released the World Population Prospects Report every two years since 1951.

Key Findings

• The UN report projects a peak in the world population by the mid-2080s, followed by a decline by 2100 due to decreasing fertility rates.
• India’s population will continue to grow until the mid-2060s due to population momentum despite crossing the replacement fertility rate.
• Global population likely to peak within this century with 80% probability, up from 30% a decade ago.
• 63 countries (28% of the global populace) peaked before 2024; 48 countries (10%) to peak between 2025 and 2054; the remaining 126 countries, including India, will continue growing mid-century or beyond.
• Current population at 8.2 billion is expected to reach 10.3 billion by mid-2080s, then decline to 10.2 billion by century’s end.
• Average birth rate decreased from 3.3 in 1990 to 2.3 currently.

Increasing Indian Population

{GS3 – Envi – Conservation} Use of Ionic Liquids (ILs) in Silk protein extraction

• Context (PIB): Researchers have identified Ionic Liquids (ILs) that can be promising sustainable alternatives to the toxic chemicals currently in use for the silk protein extraction process.

• Ionic Liquids (ILs) are salts that remain in a liquid state at relatively low temperatures and are known for their low toxicity and ability to dissolve a wide range of materials.
• ILBs showing greatest promise included 1-Butyl-3-methylimidazolium chloride (BMIM.Cl), 1-ethyl-3-methylimidazolium tetrafluoroborate (EMIM.BF4), and Tetraethylammonium bromide (TEAB).

Credits: PIB

• Traditionally, toxic chemicals like sodium carbonate, sodium hydroxide, sulfuric acid, and lithium bromide have been used to extract silk proteins, fibroin, and sericin from various types of raw silk fibres.
• These chemicals are health hazardous for those involved in the process and contribute to carbon emissions and environmental pollution as the chemicals are released into the water.

• Significance: Extraction of sericin from non-mulberry silks using ILs opens new possibilities for utilising these unique fibres in various applications, including textiles, cosmetics, and biomedical products.

About Ionic Liquids (ILs)

• Ionic liquids are a unique class of organic compounds that are entirely composed of ions.
• Unlike typical liquids, which consist of neutral molecules, ionic liquids are entirely made up of positive (cations) and negative (anions) ions.

Properties

• Zero or no vapour pressure, i.e. they do not evaporate easily.
• Non-flammable, High thermal stability, Low melting point
• Easily recyclable and Good conductors (electrolytes)

Potential applications

Credits: Science Direct

• ILs are utilised in green energy storage and conversion devices like fuel cells, lithium-ion batteries, supercapacitors, and solar cells due to their eco-friendly nature and high ionic conductivity.
• They are used in drug formulation and delivery to address challenges like drug solubility, permeability, and formulation instability, offering potential solutions for enhancing drug delivery systems.
• In the oil industry, it is used for pollutant removal, demulsification, and oil recovery.

{GS3 – Envi – Issues} Hanle Valley and irresponsible tourism **

• Context (TH): As the summer rush peaks, rash development and irresponsible tourism threaten Ladakh’s unique animals and environment.

Hanle valley

• It is located in Eastern Ladakh near the Indo-China border at an average altitude of 4,500 m above sea level and is part of the Changthang Wildlife Sanctuary.
• It is inhabited by Changpa nomadic herders, who rear sheep, pashmina goats, horses and yaks.
• Notable animals: Pallas’s cat, Tibetan sand fox, snow leopard, and black-necked crane.
• Sighting of the Tibetan sand fox, Pallas’s cat (nicknamed the world’s grumpiest cat) and the black-necked cranes popularised the valley.
• The construction of Hanle Dark Sky Reserve and Umling La motorable road has led to increased tourism.
• Several military outposts have been established after the recent Indo-China skirmishes.

Impacts of Irresponsible Tourism

• Proliferation of stray dogs: Dogs preying on leftovers have risen, leading to a decline in the prey population of Snow leopards, including Pallas’s cats, Tibetan sand foxes, and bar-headed geese.
  • They even hybridise with the Tibetan wolf, diluting the latter’s gene pool.
• Rangeland degradation: Irresponsible tourists ride roughshod over pasturelands, destroying the topsoil. Added to global warming, it compromises the rangeland’s health, impacting the nomadic locals.
• Irresponsible driving: SUVs chasing animals, blaring music and glaring headlights, rash driving impacts animals even to the extent of death.
  • Pallas’s cat is especially vulnerable because the roads run along cliff bases, bisecting the cats’ habitat.
• Water availability: Indus River is burdened by consumption, irresponsible use, and retreating glaciers.
• Water contamination: A flawed policy mandating flush toilets leads to water flowing into the water sources, exposing the villagers to waterborne disease.
• Water oxygen depletion: Dumping of waste leads to an explosion of invertebrates, which, in turn, depletes dissolved oxygen.

Way forward

• Organic waste to organic manure: Organic manure can be produced from organic waste, especially when Ladakh aspires to be an organic UT.
• Limiting the tourists: To limit the burden of tourism, a system similar to the Inner Line Permit (in the 2000s) can be implemented.

{GS3 – IE – RBI} Liberalised Remittance Scheme (LRS)

• Context (TH): RBI allowed resident individuals to open Foreign Currency Account in International Financial Services Centres (IFSCs) at GIFT City in Gujarat under the Liberalised Remittance Scheme.

• Authorised Persons may facilitate remittances for availing financial services or financial products as per the International Financial Services Centres Authority Act, 2019, within IFSCs.

• It will allow resident Indians to open a fixed deposit in dollars in a bank account at GIFT IFSC.

What is Liberalised Remittance Scheme?

• The Liberalised Remittance Scheme is an RBI measure that allows Indian residents, including minors, to send up to USD250,000 per financial year (April to March) outside India.
  • In case of the remitter being a minor, the LRS declaration form must be countersigned by the minor’s natural guardian.
• There are no restrictions on the frequency of remittances under LRS. However, the total amount through all sources in India during a financial year should be within the cumulative limit of USD 2,50,000.
• The remittances can be made in any freely convertible foreign currency.

Eligibility

• The LRS is for people who are residents of India as defined by Foreign Exchange Management Act.
• The eligible citizens must have an Indian bank account, a valid Permanent Account Number (PAN), and a passport.
• Non-residential Indians are not supposed to have any savings accounts in Indian banks. Thus, they cannot remit funds from India, but they are permitted to transfer funds from NRO, NRE, and FCNR accounts abroad.
• It cannot be used by corporations, partnership firms, Hindu Undivided Family (HUF), trusts, etc.

Permissible transactions

• The remitted funds can be used for any permissible current or capital account transaction or a combination of both.

{GS3 – S&T – AI} COPIED draft bill

• Context (IE): To combat the rise of AI-generated deepfakes, the US introduced the Content Origin Protection and Integrity from Edited and Deepfaked (COPIED) Media Bill.

• Online platforms would require users to tag such synthetic content with information about its origin.
• The COPIED bill will also allow creators, including local journalists, artists, and musicians, to regain control of their content through a provenance and watermark process.
• The bill tasks various US government agencies, such as the US National Institute of Standards and Technology (NIST), the US Patent and Trademark Office (USPTO), and the US Copyright Office, to develop detection and watermarking standards.

Scope of the draft bill

• Defines ‘deepfake’ as synthetic or synthetically modified content that appears authentic to a reasonable person and creates a false understanding or impression.
• This would include images, videos, audio clips, and text that have either been wholly generated or significantly modified using AI tools.
• Applicable to any online app or platform with US-based customers, with an annual revenue of $50,000,000 or over 25,000,000 monthly active users for three months.

Provisions for platforms

• Platforms need to give users the option to attach content provenance information to synthetic content.
• Tampering with the attached information would be illegal except for research purposes.
• It also prohibits platforms from using copyrighted material with content provenance information to train AI models or generate content.

{GS3 – S&T – Space} Black Holes

• Context (DTE): Hubble space telescope uncovers an intermediate-mass black hole hiding within the Milkyway galaxy‘s Omega Centauri star cluster.

• Black holes are immense gravitational wells with immense amounts of matter packed into a tiny space.
• They don’t emit or reflect light, making it invisible to telescopes. So, they are studied based on how they affect their surroundings.
• They are characterised by extreme density and powerful gravitational pull and are capable of bending the fabric of space and time.

{Prelims – Bio – Diseases} Plague behind Neolithic decline

• Context (IE): A new study, “Repeated plague infections across six generations of Neolithic Farmers”, suggests that plague may have been the primary driver behind the ‘Neolithic decline’.

• Around 5,000 years ago, the population in northern Europe collapsed, decimating Stone Age farming communities across the region.
• Researchers determined that the last strains of the plague-causing bacterium Yersinia pestis may have been more virulent to cause the epidemic.
• A later form of this same pathogen caused the Justinian Plague of the 6th century AD and the 14th-century Black Death, ravaging Europe, North Africa, and the Middle East.

Also refer to the Bubonic Plague (Black Death).

{Prelims – Envi – Species} Squalus hima

• Context (TH): Scientists have discovered a new species of deep-water dogfish shark Squalus hima from Sakthikulangara fishing harbour in Kerala along the Arabian Sea.

Credits: TH

• Squalus is a genus of dogfish sharks in the family Squalidae, commonly known as spurdogs. They are characterised by smooth dorsal fin spines.
• The newly discovered species differs from others by the number of teeth counts, trunk and head heights, fin structure and fin colour.
• The species are characterised by an angular short snout, a small mouth almost as wide as the snout, first dorsal fin origin behind the pectoral fins, and a body without any spots.
• They are exploited for their liver oil, which contains high levels of squalene (or squalane when it is processed for products).
• It is in high demand in the pharmaceutical industry, particularly in the production of high-end cosmetic products and anti-cancerous products.
• On the Indian coast two species of Squalus are found on the southwest coast of India. The new species, Squalus hima n.sp., is very similar to Squalus lalannei but differs in many characteristics.

{Prelims – Sci – Physics} Time Crystals

• Context (Phys): Scientists successfully created a time crystal made of giant atoms.

About Time Crystal

• Time crystals represent a new phase of matter, first theorised in 2012 by Nobel laureate Frank Wilczek.
• Regular crystals have a repeating pattern in space, while time crystals have a repeating pattern in time.
• This means that regular crystals have a fixed structure that does not change over time, while time crystals have a structure that changes and repeats itself over time.
• They defy the traditional laws of thermodynamics that govern equilibrium in most systems.
• They oscillate between states without using energy. They exhibit ‘time-translation symmetry breaking‘ property, which means they oscillate between different states in a time-periodic manner.
• Time crystals are created by using a process called “driving”. This involves applying a periodic force to a system of particles, causing them to move in a specific pattern.
• This pattern then repeats itself over time, creating a time crystal.

Potential applications

• Time crystals could be used to create more stable qubits. The stability could pave the way for more reliable quantum computers, capable of solving complex problems.
• The intrinsic temporal regularity of time crystals makes them ideal candidates for enhancing the precision of timekeeping devices. They may improve data storage and encryption techniques.
