About Sawalkote Hydroelectric Project:

• It is a 1,856-MW hydropower plant on the Chenab River in the Udhampur and Ramban districts of Jammu and Kashmir.
• It has been designed as a run-of-the-river scheme located between the Baglihar project upstream and the Salal project downstream, making it part of a continuous chain of hydropower installations on the Chenab.
• It will be the largest hydroelectric project in the Union Territory and one of the biggest in North India.
• It is being built by the National Hydroelectric Power Corporation (NHPC).
• It will comprise nine turbines and an underground power station.
• It will produce around 8000 million units of electricity every year.
• By regulating the flow of the Chenab River, the Sawalkote project could contribute to flood mitigation downstream, while also ensuring better water management for agriculture and domestic use.
• It is a key part of India’s plan to fully utilise its share of water from the western rivers under the 1960 Indus Waters Treaty (IWT).
• It is the first major hydropower project on the Indus river to be accorded environmental clearance following India’s suspension of the Indus Waters Treaty (IWT) in 2025, following the Pahalgam terror attack.

About Psammophaga holzmannae and Psammophaga sinhai:

• They are two new species of microscopic marine organisms that selectively pick up and swallow specific mineral grains from the seafloor.
• They were found at Rajapuri Creek in Raigad district along Maharashtra’s Konkan coast.
• Psammophaga is a type of foraminifera, a group of microscopic organisms commonly found in oceans.
• The name comes from Greek words meaning 'sand eater'.
• Unlike many foraminifera that have hard, multi-chambered shells, these organisms have just one chamber and a soft wall made mainly of very fine clay particles.
• The most interesting discovery was what the organisms choose to eat.
  • Both species selectively take in heavy minerals containing titanium and iron. These include ilmenite and magnetite.
  • This is important because these minerals occur only in small amounts in the surrounding sediment.
• How do they do it?
  • Psammophaga uses thin, temporary hair-like extensions called granuloreticulopodia.
  • These extend from the aperture and help the organism interact with the surrounding sediment.
  • Scientists believe these extensions may help the organism detect differences between mineral grains, although the exact mechanism is still not known.

About Methamphetamine:

• It is a powerful, highly addictive stimulant that affects the central nervous system.
• It is also known as meth, chalk, ice, and crystal.
• It was developed early in the 20th century from its parent drug, amphetamine, and was used originally in nasal decongestants and bronchial inhalers.
• Properties of Methamphetamine:
  • It is a member of the class of amphetamines.
  • It takes the form of a white, odorless, bitter-tasting crystalline powder that easily dissolves in water or alcohol.
  • It has a role as a neurotoxin, a psychotropic drug, a central nervous system stimulant, a xenobiotic and an environmental contaminant.
• Impact of Methamphetamine on Humans:
  • It causes increased activity and talkativeness, decreased appetite, and a pleasurable sense of well-being or euphoria. 
  • The use of methamphetamine in higher doses can induce psychosis, bleeding in the brain, skeletal muscle breakdown, and seizures.

About Glyphosate:

• It is a widely used herbicide that can kill certain weeds and grasses.
• It is considered a broad-spectrum herbicide, meaning it can effectively control a wide variety of plants, including grasses, broadleaf plants, and woody plants.
• Impact of Glyphosate:
  • Herbicidal Action: It works by inhibiting an enzyme called EPSP synthase, which is essential for the synthesis of certain amino acids that plants need for growth.
    • It disrupts this enzyme; glyphosate interferes with the plant’s ability to produce proteins, leading to the eventual death of the plant.
  • Broad-Spectrum: It is effective only on plants that grow above the water.
    • It will not be effective on plants that are submerged or have most of their foliage underwater, nor will it control regrowth from seed.
  • It is degraded in soil and water by microbes and binds tightly to soil particles, which prevents the leaching of glyphosate into groundwater.
  • It does not degrade quickly in plants. As a result, it is possible that glyphosate residues can occur in food products.
