2. What is the Society for Worldwide Interbank Financial Telecommunication (SWIFT) System?
A Russian envoy in India recently called for an alternative to the SWIFT system used for global payments, from which Russia was expelled after the beginning of war in Ukraine.
About SWIFT System:
- It is a member-owned cooperative that provides safe and secure financial transactions for its members.
- Establishment: It was founded in 1973 by 239 banks from 15 countries.
- SWIFT is a network that banks use to communicate with each other securely, mainly to give instructions for transferring funds between accounts.
- SWIFT is the largest and most streamlined method for international payments and settlements.
- SWIFT works by assigning each financial organization a unique code with either eight or 11 characters, known as a bank identifier code, or BIC.
- By standardizing communication protocols, SWIFT ensures that financial institutions can reliably conduct cross-border transactions, reducing the risks and inefficiencies associated with international banking.
- Although SWIFT is crucial to global financial infrastructure, it's not a financial institution.
- SWIFT does not hold or transfer assets but facilitates secure, efficient communication between member institutions. It transmits essential details such as the recipient’s account information and transfer amount.
- Headquartered in La Hulpe, Belgium, the system is overseen by the central banks of the G10 countries, the European Central Bank, and the National Bank of Belgium.
- Its shareholders represent around 3,500 member organisations.
- SWIFT shareholders elect a board of 25 directors who govern the organisation and oversee management of the SWIFT system.
- Because membership in SWIFT allows countries to easily conduct international financial transactions, exclusion from SWIFT is an economic sanction that can be used against countries whose actions are condemned by the global community.

7. Hyperuniformity
Researchers have explored the mechanism behind the emerging property of recently discovered exotic disordered states of matter, known as “hyperuniformity”.
About Hyperuniformity:
- It is a property of certain heterogeneous media in which density fluctuations in the long-wavelength range decay to zero.
- Hyperuniform disordered materials have been observed in a variety of settings, such as in quasicrystals, large-scale structures of the universe, soft and biological emulsions and colloids, etc.
- Feature: One of the most striking characteristics of such a state is that mass fluctuations are greatly suppressed as the system size grows.
- Applications:
- Hyperuniform materials have distinctive characteristics that could have technological or biological applications.
- The mechanism of hyperuniformity could be used to control various physiological functions in cells, and energy-efficient photonic devices (such as photonic band-gap materials)
- It could be used for optical data transmission and communications.
8. What are Trojan asteroids?
Scientists have finally discovered a Trojan asteroid for Saturn, thereby establishing the presence of these celestial bodies alongside all giant planets in our solar system.
About Trojan asteroids:
- Trojan asteroids are a class of asteroids that occupy a stable Lagrange Point in a planet’s orbit around the sun.
- These are usually found around Lagrange Point L4 or L5 points which makes them gravitationally stable.
- These are thought to be remnants of the primordial materialthat formed the outer planets.
- Their orbit around the sun is similar to the orbit of the planet they are associated with.
- These were discovered by German astrophotographer Max Wolf in 1906, but they were named so later.
- They have unusual orbits, remain gravitationally stable for long periods of time and studying them can provide useful insights into the evolution of the solar system.
What are Lagrange points?
- A Lagrange point is a position in space where the gravitational pull of two large masses precisely equals the centripetal force required for a small object to move with them.
- These points in space can be used by spacecraft to reduce fuel consumption needed to remain in position.
- The Lagrange points are named in honour of Italian-French mathematician Josephy-Louis Lagrange, and there are five of them: L1, L2, L3, L4, and L5.
- The L1 point of the Earth-Sun system affords an uninterrupted view of the Sun.
- It is currently home to the Solar and Heliospheric Observatory Satellite SOHO.
9. Long-billed Vulture
A study published recently has highlighted that the population of the critically endangered long-billed vulture has seen a steady increase between 2015 and 2021, with the species exhibiting a 74% breeding success rate in the Mudumalai Tiger Reserve (MTR).
About Long-billed Vulture:
- It is an old World vulture native to Asian region.
- They are also known as Indian long-billed vultures due to their comparatively longer beak.
- It is a medium-sized and bulky scavenger feeding mostly on the carcasses of dead animals.
- Females of this species are smaller than males.
- Habitat: They are usually found in savannas and other open habitats around villages, cities, and near cultivated areas.
- Distribution: These are native to India, Pakistan, and Nepal.
- Conservation status
- IUCN Red List: Critically Endangered
