Lohit River

ЁЯФ╣ Why in News & Recent Development

A tragic accident occurred recently when a Delhi-registered vehicle carrying 10 people fell into the Lohit River in Arunachal Pradesh, resulting in casualties and missing persons, bringing focus back to the treacherous terrain and geographical features of this northeastern river system.

ЁЯФ╣ Key Conceptual & Analytical Details

The Lohit River originates in eastern Tibet in the Zayal Chu range and surges through Arunachal Pradesh before joining the Brahmaputra in Assam. Known as the 'River of Blood' due to the abundance of laterite iron-heavy soil in the Mishmi Hills, it is a fast, fierce, and unpredictable tributary with major right-bank tributaries like Dau, Dalai, and Tidding, and left-bank tributary Lang.

ЁЯФ╣ Strategic Importance & Future Impact

The river plays a pivotal role in the local economy of Arunachal Pradesh, supporting drinking water supplies, agriculture, and hydroelectric potential. Its lower reaches also hold immense cultural and religious significance due to the sacred Parshuram Kund Hindu pilgrimage site.

Dipturus dhritiae (Arabian Skate)

ЁЯФ╣ Why in News & Recent Development

Scientists from the Zoological Survey of India (ZSI), in collaboration with the ICAR-Central Marine Fisheries Research Institute (CMFRI) and international experts, discovered a new deep-sea skate species named Dipturus dhritiae in the southeastern Arabian Sea.

ЁЯФ╣ Key Conceptual & Analytical Details

Commonly known as the Arabian skate, Dipturus dhritiae is a flat, shark-related fish living on the dark ocean floor at depths of 400 to 600 metres off the Kerala coast and Wadge Bank. It features five rows of thorn-like structures along its tail and is named in honor of Dr. Dhriti Banerjee, the first woman Director of the ZSI.

Peptides: Science and Regulation

ЁЯФ╣ Why in News & Recent Development

Regulatory authorities in Karnataka recently shut down an unauthorized 'peptide party' in Bengaluru, highlighting emerging public health concerns regarding the unregulated recreational use of synthetic peptides.

ЁЯФ╣ Key Conceptual & Analytical Details

Peptides are shorter chains of amino acids (typically containing between two and 50 amino acids) linked by peptide bonds, serving as the fundamental building blocks of proteins. Naturally produced peptides include insulin and endorphins, while synthetic variants are widely utilized as therapeutics, weight-loss drugs (e.g., GLP-1 receptor agonists), and biological signaling molecules.

ЁЯФ╣ Strategic Importance & Future Impact

While legitimate peptides are crucial for metabolic regulation, tissue repair, and advanced medicine, their unsupervised gray-market consumption for bodybuilding or anti-aging poses serious clinical risks, demanding stricter drug administration oversight.

Indus Waters Treaty & Court of Arbitration Ruling

ЁЯФ╣ Why in News & Recent Development

India formally rejected the Hague-based Court of ArbitrationтАЩs (CoA) recent ruling that challenged IndiaтАЩs decision to place the Indus Waters Treaty (IWT) in abeyance, asserting that the tribunal lacks jurisdictional competence.

ЁЯФ╣ Key Conceptual & Analytical Details

Brokered by the World Bank in 1960, the IWT divides the eastern rivers (Ravi, Beas, Sutlej) to India and western rivers (Indus, Jhelum, Chenab) largely to Pakistan. The current legal standoff stems from simultaneous proceedings initiated by Pakistan (requesting a CoA) and India (requesting a Neutral Expert) regarding run-of-the-river projects like Ratle and Kishenganga, violating the treaty's sequential dispute resolution framework.

ЁЯФ╣ Strategic Importance & Future Impact

India's firm stance underscores its sovereign right to reassess bilateral treaties in the wake of persistent cross-border terrorism, highlighting structural limitations in international arbitration mechanisms governing transboundary water pacts.
