Scientists Discover 'Dark Oxygen' in Pacific Ocean, Challenging Long-Standing Theories

INIndia|

Researchers have identified a unique phenomenon known as "dark oxygen" produced by certain rocks in the Pacific Ocean, challenging the conventional belief that oxygen generation is solely dependent on photosynthesis. According to the study, these polymetallic nodules, resembling coal piles at ocean depths, can generate oxygen through electrochemical reactions without sunlight.

Traditionally, oxygen in the ocean has been understood to arise from marine plankton, algae, and bacteria that require sunlight for photosynthetic processes. This discovery indicates that oxygen can also be produced in environments where sunlight is absent, potentially supporting aerobic life in deep, oxygen-poor regions.

The oxygen production occurs through interactions between the rare metal deposits on the ocean floor and saltwater, facilitating the splitting of water molecules (H2O) into hydrogen and oxygen. Researchers believe that this revelation expands our understanding of oxygen generation, potentially reshaping scientific theories regarding deep-sea ecosystems.

The findings present a significant breakthrough in marine science, illustrating the complex interactions of geological and biological processes that govern life in the ocean's dark depths.

Rajasthan NGO Busted for Human Trafficking Under Mass Marriage Scam

Authorities in Rajasthan have dismantled a human trafficking operation disguised as a non-governmental organization (NGO) that falsely claimed to facilitate mass marriages for women from impoverished backgrounds. The Gayatri Sarva Samaj Foundation, located in a farmhouse near Bassi, allegedly bought girls from agents trafficking children from Bihar, West Bengal, Odisha, and Uttar Pradesh, selling them to young men for prices ranging between ₹250,000 to ₹500,000 (approximately $3,000 to $6,000), as reported by Bassi police station in-charge Abhijit Patil. The scheme came to light when a 16-year-old girl from Uttar Pradesh escaped and contacted police, leading to a raid on the farmhouse. During the operation, officials arrested the NGO's director, Gayatri Vishwakarma, along with three accomplices, including Hanuman, Bhagwan Das, and Mahendra. Investigators revealed that Vishwakarma had been involved in approximately 1,500 such arranged marriages and had multiple prior cases against her. Authorities also found that she falsified identification documents to misrepresent the ages of minors, indicating a deep-rooted criminal enterprise.

China-Linked Loan App Scams Estimated to Cause Over $3 Billion in Global Losses

A crackdown on China-linked loan app scams has revealed extensive operations impacting numerous countries, including India, Nigeria, and the Philippines. The Enforcement Directorate (ED) reported that two individuals were arrested in India for managing a Chinese loan app scam that involved over 500 illicit bank accounts, amassing around ₹719 crores (approximately $86 million). According to ED sources, these scams rely on data harvesting, extortion, and cryptocurrency money laundering, targeting individuals through deceptive practices such as blackmail. The global financial impact of these scams is estimated to exceed $3 billion since 2020. The China Communist Party's United Front Work Department and the Ministry of State Security have been implicated in facilitating these operations, which utilize shell companies and advanced cyber techniques to infiltrate foreign economies. The ED's investigation identified a network facilitating cryptocurrency transfers to overseas wallets, with an alarming trend of financial ruin and suicides reported among victims in India. The scope and complexity of these schemes underscore the urgent need for international collaboration to combat cybercrime.
