National Turmeric Board

The Government of India has recently notified the constitution of the National Turmeric Board (NTB).

  • NTB aims for the growth and development of turmeric and turmeric products.
  • It will provide leadership, augment the efforts and facilitate greater coordination with other agencies.
  • Objectives – To increase awareness and consumption, develop new international markets, promote R&D and to develop our traditional knowledge for value addition.
  • Focus – Capacity building and skill development of growers.
  • Significance – It will promote quality and food safety standards.
  • It ensures existing pre-eminent position as exporters of high-quality turmeric and turmeric products in the global markets.
  • It promotes prosperity of the growers and to exploit turmeric’s full potential for humanity.

Composition of the Board

  • A Chairperson who is appointed by Central Government.
  • A Secretary who is appointed Department of Commerce.
  • Other members from the
    • Ministry of AYUSH
    • Departments of Pharmaceuticals, Agriculture & Farmers Welfare, Commerce & Industry of the Union Government,

Nobel Prize in Chemistry 2023

The Nobel Prize in Chemistry 2023 was awarded to Moungi Bawendi, Louis Brus and Alexei Ekimov for the discovery and synthesis of quantum dots.

  • Independently of each other, Ekimov and Brus succeeded in creating quantum dots, and Bawendi revolutionised the chemical production of it.

Quantum Dots

  • They are nanoparticles which exhibit unique optical properties due to their small physical size.
  • Their properties can be changed by changing their size.
  • At the nanometres scale, matter exhibit size-dependent properties because quantum physical forces start to dominate.
  • Contribution of Alexei Ekimov – In the early 1980s, he succeeded in creating size-dependent quantum effects in coloured glass.
  • He demonstrated this using glasses tinted with copper chloride.
  • Contribution of Louis Brus – In 1983, he and his colleagues prepared similar crystals in a liquid solution, rather than in a glass.
  • These crystals also interacted with light differently depending on small variations in their size.
  • Contribution of Moungi Bawendi – In 1993, he developed a technique to make these crystals of well-defined sizes and with high optical quality.

Applications of Quantum Dots

  • It can light computer monitors and television screens where they can emit light of different colours.
  • They are also used to map biological tissues by biochemists.
  • In photovoltaic cells, to improve the absorption and efficiency in converting solar light into electricity.
  • It is used in treating certain cancers for targeted drug delivery and other therapeutic measures.
  • It can be used as security markers on currency and documents as an anti-counterfeit measure.
  • Broadly, they can be used as fluorescent markers to tag and track objects.

  • UTV vs. 1337x.to – For the 1st time, the concept of “dynamic” injunctions was introduced.
  • Universal City Studios LLC v. Dotmovies.baby 2023 – It protect works generated during the case’s pendency and which might be created in the future until the court rescues.
  • To take action against the rogue websites that indulge in illegalities of uploading the videos of newly released film or series.

1957 Copyright Act

  • Section 37 deals with broadcasting reproduction rights which is a “special right” extended to every broadcasting organisation.
  •  Section 37 (2) enlists infringement categories of this right.

Badis limaakumi

Scientists have recently discovered a new fish species ‘Badis limaakumi’ from the river Milak in Nagaland.

  • Taxonomy – A small freshwater fish, under the family Badidae having 26 recognised fish species.
  • It also belongs to the Badis assamensis Sub-group (SG).
  • It is also known as chameleon fish, for their ability to change colour that helps them blend with the surroundings when under stress.
  • Habitat
    • Streams with slow or moderate water flow.
    • Ditches and stagnant water bodies.
    • India, Bangladesh, Nepal, Pakistan, Thailand and Myanmar.
  • Uniqueness – It differs from other members of the Badis badis SG due to its larger size and other physical characterises.
  • It has a distinct dark opercular blotch at the base of its opercular spine.

Opercular spine is a bone series that serves as a facial support structure and a protective covering for the gills.

  • The spots on the sides and more lateral line scales are absent.

Milak River flows through Mokokchung District in Nagaland and its main tributary is Tsurong.

  • Badis in India were found in the rivers of Brahmaputra, Kaladan and Sharavati and Milak.

North Koel Irrigation Project

The Cabinet Committee on Economic Affairs (CCEA) has given its approval to a proposal Ministry of Jal Shakti to complete the balance works of North Koel Irrigation Project at a revised cost.
