Davis Strait
Syllabus: GS1/Places in News
Context
- A hidden landmass has been found beneath the icy waters of the Davis Strait.
About
- The discovery was made by a team of scientists from the UK and Sweden during a study of the ocean floor in the region.
- The landmass is now named the Davis Strait proto-microcontinent.
- It is made up of unusually thick continental crust and measures between 12 and 15 miles (around 19 to 24 kilometres).

Tobacco Farming
Syllabus: GS3/Agriculture
Context
- Andhra Pradesh Social Welfare Minister assures support to tobacco farmers facing issues with low bids and delayed procurement.
Tobacco Farming
- Tobacco cultivation in India was introduced by the Portuguese in 1605.
- India is the 2nd largest producer of tobacco in the world after China.
- India is the 2nd largest exporter of unmanufactured tobacco (quantity terms) after Brazil.
- In India tobacco is predominantly cultivated in Andhra Pradesh, Gujarat, Karnataka, UP and Bihar.
- Gujarat accounts for 45 per cent of the area and 30 per cent of production. Productivity is also highest in Gujarat followed by AP.
Climatic Conditions
- In India, tobacco is grown when the mean temperature is 20° to 27°C.
- It is not usually grown where rainfall exceeds 1200 mm during the season.
- In India, cigar and binder tobacco are grown on sandy to loamy red soils.
- It needs larger quantities of nitrogen, potassium, calcium and magnesium.
The Tobacco Board
- The Tobacco Board was established in 1976 by the Tobacco Board Act, 1975.
- The Board’s primary role is to ensure the smooth functioning of the farming system and to ensure fair and remunerative prices for tobacco farmers and the promotion of exports.

Safeguard Duty
Syllabus: GS3/ Economy
Context
- India has imposed a 12% provisional safeguard duty for 200 days on five categories of steel products to protect domestic producers from a surge in low-cost imports.
Safeguard Duty
- A safeguard duty is a temporary measure used to limit the import of a specific good to prevent serious harm to a domestic industry.
- It is permitted under World Trade Organization (WTO) rules.
- These duties typically have a deadline and are applicable against all the countries with uniform rate of duty unlike the anti-dumping duties.
- These are considered an emergency action and are deemed necessary only when certain imports present serious injury or damage to domestic industries.

Lipids & RC1 Complex
Syllabus: GS3/ Science and Technology
Context
- A new study challenges the traditional view that lipids are merely structural components, revealing their active role in cellular evolution and mitochondrial function.
What are Lipids?
- Lipids are fatty compounds that make up 30% of the dry weight of living cells.
- It plays critical roles in the body which includes; Energy storage, Hormone production, transport of fat-soluble vitamins like A, D, E, and K.

- There are two types of cholesterol;
- LDL (low-density lipoprotein), often referred to as ‘bad’ cholesterol because it can accumulate in the walls of arteries and contribute to severe diseases, and
- HDL (high-density lipoprotein), known as ‘good’ cholesterol.
RC1 Complex
- The RC1 (Respiratory Complex I) is a group of proteins embedded in the inner mitochondrial membrane of all aerobic eukaryotic cells.
- It is vital for cellular respiration, the process of converting oxygen and nutrients into energy.
- In humans, RC1 comprises 44 proteins, some encoded by nuclear DNA and others by mitochondrial DNA.
- These proteins must assemble accurately in the lipid-rich mitochondrial membrane for efficient function.
Optical sensing platform for cholesterol detection – An optical sensing platform developed by the Institute of Advanced Study in Science and Technology (IASST), Guwahati allows early detection of cholesterol, a key lipid based on phosphorene quantum dots functionalized on silk fibre. – It detects cholesterol in trace amounts, including in human blood serum. – It can be developed as a Point-of-Care (POC) device for personalized health monitoring. |
Nano-sulphur
Syllabus: GS3/Agriculture
Context
- The Energy and Resources Institute (TERI) scientists claim that the nano sulphur developed by them increases the yield of mustard by 30-40%.
About
- DMH-11, the genetically-modified mustard, increases average per hectare yield by 10-40 per cent in various multi-site trials conducted so far.
- Existing mustard varieties give an average per hectare yield of around 1-1.8 tonne.
- Significance of Nano Sulphur:
- It is a completely green product that uses biological agents like plant promoting bacteria that secrete enzymes and metabolites.
- It also replaces up to 50% of traditional sulphur fertilisers and can lead to an additional earning of up to ₹12,000 per acre for farmers.
- Cost Effective: A 500 millilitre bottle of nano sulphur will cost a farmer around ₹450 while a bag of conventional sulphur in different grades varies from ₹900-1,800.
Sulphur
- Sulphur is a key component of amino acids like cysteine and methionine, which are building blocks of proteins.
- This is especially important in legumes, oilseeds (like mustard), and cereals.
- Sulphur boosts oil content in oilseeds (e.g., canola, sunflower).
- It improves grain quality in cereals like wheat and enhances flavor in onions, garlic, and other alliums.

Galaxy NGC 1052-DF2
Syllabus :GS 3/Space
In News
- Astronomers at the Indian Institute of Astrophysics (IIA) have investigated the unusual lack of dark matter in the galaxy NGC 1052-DF2, which challenges standard galaxy formation theories.
Dark matter
- It makes up about 27% of the universe but doesn’t interact with light, making it invisible and detectable only through its gravitational effects.
- Dark matter and dark energy are mysterious components of the universe, making up about 95% of it.
- The remaining less than 5% includes everything we can see and understand, like Earth and observable matter.
NGC 1052-DF2
- It is an ultra-diffuse galaxy the size of the Milky Way but with far fewer stars and only 1/400th the expected dark matter.
- It is unique for its extreme dark matter deficiency, making it a rare anomaly even among ultra-diffuse galaxies.
- It has a total mass of around 340 million solar masses—mostly from stars—indicating very little dark matter compared to typical galaxies like the Milky Way.
Latest Developments
- Researcher K. Aditya modeled the galaxy using stellar density data and found that mass models with a “cuspy” dark matter halo (dense in the center) did not match observed data.
- These findings suggest that the galaxy may either lack dark matter or contain it in a very diffuse form, prompting new questions about galaxy formation and the nature of dark matter.
Do you know ? – Ultra-diffuse galaxies (UDGs) are a type of low-surface-brightness galaxy that have a large size but very few stars, making them appear extremely faint and spread out compared to galaxies like the Milky Way. |
