Small Modular Reactors:

The Indian Government is considering offering incentives, similar to a production-linked incentive (PLI) scheme, to encourage the manufacturing of small modular reactors (SMRs) with the goal of increasing nuclear power’s share in India’s energy production.

  • The government aims to attract private investments and scale up SMR production to reduce costs.
  • PLI schemes, introduced in 2020, provide financial incentives based on a share of the sales value and have been implemented in various sectors.
  • Small modular reactors (SMRs) are advanced nuclear reactors with a power capacity of up to 300 MW(e) per unit.
  • This is about one-third of the generating capacity of traditional nuclear power reactors.
  • SMRs are smaller than conventional nuclear reactors and can be built in one location, such as a factory, then shipped, commissioned, and operated at a separate site.
  • This offers significant savings in cost and construction time.
  • SMRs Can produce a large amount of low-carbon electricity

India Flags Off First International Cruise Liner:

The Union Minister of Ports, Shipping & Waterways flagged off the maiden voyage of the vessel Costa Serena, the first International Cruise Liner in India from Mumbai.

  • The initiative aligns with the “Dekho Apna Desh” campaign, reflecting the government’s emphasis on promoting tourism.
  • The development of cruise and lighthouse tourism is part of the Sagarmala Programme, which aims to establish India as the premier cruise hub in the Asia Pacific region by 2030.
  • The goal is to increase the annual number of cruise passengers in India to 18 lakhs by 2030, up from the current figure of 4.72 lakhs.
  • India plans to have 25 operational cruise terminals by 2047, with an estimated annual passenger count of 5 million.

Asteroid Dinkinesh:

NASA’s Lucy spacecraft, on a mission to observe Jupiter’s Trojan asteroids, recently made an unexpected discovery.

  • It found that the main belt asteroid Dinkinesh, which it was set to fly by, is actually a binary system of two asteroids bound together.
  • Preliminary analysis suggests that the larger asteroid is about 790 meters wide, while the smaller one is approximately 220 meters in size.
  • An asteroid is a rocky, metallic, or icy minor planet that orbits within the inner Solar System.
  • Asteroids are smaller than planets but larger than meteoroids. They can range in size from 1-meter rocks to a dwarf planet almost 1000 km in diameter.
  • Asteroids are remnants left over from the early formation of our solar system about 4.6 billion years ago.
  • Most of them can be found orbiting our Sun between Mars and Jupiter within the main asteroid belt.
  • Asteroids are also known as minor planets or planetoids.
  • The larger forms of asteroids are also known as planetoids.

Lamprey : Two New Species

Chinese palaeontologists have discovered two new species of lamprey from fossils considered 160 million years old.

  • Lamprey species are primitive fishlike jawless vertebrates placed with hagfishes in the class Agnatha.
  • They belong to the family Petromyzonidae.
  • They live in coastal and fresh waters and are found in temperate regions around the world, except Africa.
  • The eel-like, scaleless animals range from about 15 to 100 centimetres (6 to 40 inches) long.
  • They have well-developed eyes, one or two dorsal fins, a tail fin, a single nostril on top of the head, and seven gillopenings on each side of the body.
  • They lack bones, jaws, and paired fins.
  • The skeleton of a lamprey consists of cartilage; the mouth is a round sucking aperture provided with horny teeth.
  • Not all lampreys spend time in the sea.
  • Some are landlocked and remain in freshwater. Example: sea lamprey (Petromyzon marinus).
  • Other lampreys, such as the brook lamprey (Lampetra planeri), also spend their entire lives in fresh water.
  • They are nonparasitic, however, and do not feed after becoming adults; instead, they reproduce and die.

GST Amnesty Scheme:

The finance ministry has come out with an amnesty scheme for filing appeals against Goods and Services Tax (GST) demand orders.

  • GST Amnesty Scheme will be open till January 31, 2024.
  • It will be available for entities that were unable to submit their appeals against orders issued by the tax officer on or before March 31,
  • The scheme aims to help those who missed the deadline for filing appeals due to various reasons, including administrative errors or unforeseen circumstances.
  • The entities willing to avail of the scheme will have to pre-deposit 12.5 percent of the tax demand, against 10 percent
  • This initiative can also promote enhanced compliance among taxpayers.
  • A fair and lenient approach to appeal filing encourages better cooperation with tax authorities and a willingness to resolve disputes or clarify tax matters.
  • This benefits both taxpayers and the tax administration by streamlining the appeal process and potentially reducing the need.

Alycaeus himalayae : New Snail Species

A new snail species named Alycaeus himalayae was recently discovered from a cave in Arunachal Pradesh.

  • Alycaeus himalayae is a new snail species belonging to the genus Alycaeus.
  • Alycaeus is a genus of small land snails.
  • The genus is the first to be reported in India, as this genus is restricted to Southeast Asia and not known in the Indian region.

  • The most similar shell in the vicinity is Stomacosmethis spratti from the Shan States, Myanmar.
  • It differs from all other Alycaeus species by the characteristic trumpet-like projection on the outer side of the operculum.
  • It is, so far, the only Alycaeus species inhabiting the Himalayas.
  • All other known Alycaeus species are reported from Laos, Vietnam, southern Thailand, and Peninsular Malaysia.
