• Hydropower Project Approval: The governments of Assam and Meghalaya have agreed to move forward with a 55 MW hydropower and irrigation project near Ukiam.
• Dolphin Habitat Threat: The river is one of the last few refuges for the Gangetic River Dolphin (Platanista gangetica). Experts warn that the dam's 62-metre height will cause irreversible ecological damage to their nesting sites.
• Illegal Sand Mining: Rampant mechanised sand mining has reduced water levels to less than one metre in several stretches, leaving dolphins stranded in small pools.
• Tribal Protests: Communities such as the Rabha, Garo, and Khasi have intensified protests, fearing displacement from at least 19–25 villages and the loss of traditional land rights. 

• Origin: It is a south-bank tributary of the Brahmaputra. It originates from the West Khasi Hills of Meghalaya at an elevation of over 1,800 metres.
• Formation: The river is composed of three streams: the Khri, Krishniya, and Umsiri. It is known as the Khri River in its upper catchments.
• Course:
  • It flows north from Meghalaya and enters Assam at Ukium in the Kamrup district.
  • It traverses approximately 220 km (100 km in Meghalaya and 120 km in Assam).
  • It finally joins the Brahmaputra River near Nagarbera.
• Biodiversity: It is a "hotspot" for the Gangetic Dolphin (locally called Sihu), which is India's National Aquatic Animal. The river also supports over 200 species of fish and several species of turtles.
• Ecological Status: The river is considered shallow (70–80 metres wide) and highly sensitive to anthropogenic pressures like industrial construction and motorboat traffic. 

• Sand Mafia: Large-scale illegal transportation of sand (reportedly 50–70 trucks daily) has altered the river's flow and destroyed spawning grounds for fish.
• Industrial Encroachment: Construction of boundary walls and industrial units near the Kulsi-Batha confluence has disrupted primary dolphin habitats.
• Water Scarcity: Due to mining and diversion, the river has reportedly gone virtually dry in its first 10 kilometres near Kukurmara during recent dry seasons. 

• Establishment: Formed in 2015 under Section 9C of the Mines and Minerals (Development and Regulation) Act, 1957.
• Status: Transitioned into a "Non-profit Autonomous Body" following the 2021 MMDR Amendment to provide greater operational flexibility.
• Two-Tier Structure:
  • Governing Body: Apex body chaired by the Union Minister of Mines; provides policy direction.
  • Executive Committee: Chaired by the Secretary, Ministry of Mines; manages day-to-day administration and project approvals. 

• Accrual: Funded primarily through a levy on miners.
• Contribution: Holders of mining leases pay an amount equivalent to 2% of the royalty (some recent documents suggest a move toward 3% for specific categories) to the NMET fund.
• Utilization: Funds are used for regional and detailed exploration, aerial geophysical surveys, and capacity building. 

• Deep-seated Minerals: Funding specialized projects to find concealed deposits (e.g., gold, copper, diamonds).
• Strategic Independence: Prioritizing Critical Minerals like Lithium, Cobalt, and Rare Earth Elements (REEs) essential for EVs and green energy.
• Data Generation: Building the National Geoscientific Data Repository (NGDR) to make geological data public and attract private investment.

• Project Volume: Approved over 680 projects to date with an estimated cost exceeding ₹3,500 crore.
• Auction Facilitation: Funded exploration for blocks that have since been successfully auctioned, generating significant revenue for state governments.
• Private Participation: Notified over 16 Private Exploration Agencies (NPEAs) to break the government monopoly on exploration. 

• State: Located in the Kamrup Metropolitan district of Assam.
• Proximity: It is situated on the eastern fringe of Guwahati city, making it a vital "green lung" for the urban population.
• Composition: It was declared a sanctuary in 2004 by combining three reserved forests:
  1. Amchang
  2. South Amchang
  3. Khanapara 

• Mammals: Known for the Asian Elephant, Chinese Pangolin, Flying Fox, Slow Loris, and the Hoolock Gibbon.
• Birds: Home to over 250 species, including the Lesser Adjutant Stork, Greater Adjutant Stork, and the Slender-billed Vulture.
• Vegetation: Predominantly Khasi Hill Sal forests and Eastern Himalayan moist deciduous forests, interspersed with bamboo brakes.
• Reptiles: Houses the Python, Monitor Lizard, and various species of tortoises. 

• Illegal Settlement: Rapid urbanization of Guwahati has led to the "eating away" of the forest edges by settlers.
• Stone Quarrying: Illegal mining and stone crushing in the vicinity have caused significant noise pollution and habitat fragmentation.
• Habitat Isolation: The sanctuary is largely isolated from other large forest tracts, forcing wildlife into "islands" surrounded by human development.

• Definition: A simple sugar (monosaccharide) known as "fruit sugar."
• Sources: Naturally found in fruits, honey, and root vegetables.
• Commercial Use: Extracted from corn to make High-Fructose Corn Syrup (HFCS), used in sodas, candies, and processed snacks.
• Sweetness: It is the sweetest of all naturally occurring carbohydrates. 

• Liver-Centric: Unlike glucose (which cells throughout the body use for energy), fructose is metabolized almost entirely in the liver.
• Insulin Response: It does not stimulate insulin secretion or the "fullness" hormone (leptin) as much as glucose does.
• Conversion: Excessive fructose is converted into triglycerides (fats) by the liver, leading to fatty liver issues. 

• Metabolic Syndrome: Linked to insulin resistance, high blood pressure, and obesity.
• Uric Acid: Fructose metabolism produces uric acid; high levels can lead to gout and kidney stones.
• Leaky Gut: Can increase intestinal permeability, leading to low-grade chronic inflammation.
• Addictive Properties: It triggers the dopamine reward system in the brain, similar to some addictive substances. 

• In Fruit: Generally considered safe because it comes with fiber, which slows down absorption and prevents liver overload.
• In Processed Food: Highly concentrated and lacks fiber, causing rapid "spikes" that damage metabolic health. 

Feature	Fructose	Glucose
Metabolism	Mainly in the Liver	Every cell in the body
Glycemic Index	Low (approx. 19)	High (approx. 100)
Satiety	Does not signal "full" well	Signals brain to stop eating
Main Danger	Fatty Liver / Uric Acid	High Blood Sugar / Diabetes

• Tunnelers: Burrow directly beneath a dung pat to create underground nests.
• Dwellers: Live and breed directly inside the dung pile without moving it.

• Daytime Guidance: Use the Sun and the pattern of polarized light (invisible to humans) to orient themselves.
• Dancing: Before rolling, they perform an "orientation dance" on top of the dung ball to take a celestial "snapshot." 

• Nutrient Cycling: They bury nitrogen-rich waste, significantly improving soil fertility and plant growth.
• Climate Mitigation: By burying dung, they can reduce methane and greenhouse gas emissions from livestock waste by up to 40%.
• Pest Control: Removing surface dung eliminates breeding grounds for flies and parasites that harm cattle.
• Seed Dispersal: They indirectly help reforest areas by burying seeds found in herbivore dung.

• Master Antioxidant: It is the most powerful antioxidant produced naturally by the human body.
• Composition: A tripeptide made of three amino acids: Cysteine, Glycine, and Glutamic acid.
• Location: Found in every cell, but concentrations are highest in the liver, where it aids in detoxification. 

• Neutralizes Free Radicals: Prevents cell damage caused by reactive oxygen species (ROS).
• Detoxification: Binds to toxins (like heavy metals and pollutants) to make them water-soluble so the body can flush them out.
• Immune Support: Helps T-cells function properly, which is essential for fighting infections.
• DNA Repair: Plays a role in synthesizing and repairing DNA. 

• Melanin Inhibition: It inhibits the enzyme tyrosinase, which produces melanin (the pigment that darkens skin).
• Switching Pigment: It shifts melanin production from eumelanin (dark) to pheomelanin (lighter/yellow-red), leading to a brighter complexion.
• Anti-Aging: Reduces fine lines by protecting collagen from oxidative damage. 

• IV Dangers: Rapid administration can cause anaphylactic shock, kidney failure, or severe skin rashes (Stevens-Johnson syndrome).
• Thyroid Issues: Long-term use of high-dose supplements may disrupt thyroid function.
• Zinc Depletion: Chronic supplementation can lower zinc levels in the body.
• Lack of Regulation: Many "skin whitening" pills sold online are unregulated and may contain impurities. 

• Sulfur-rich foods: Garlic, onions, and cruciferous vegetables (broccoli, cauliflower).
