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

IN
Published:

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.

Innovative Watch Saves Over 100,000 Newborns from Hypothermia

An innovative temperature-tracking watch, developed by Ratul Narain, has reportedly saved over 100,000 premature newborns from the threat of hypothermia, a leading cause of neonatal mortality. According to data, India had the highest number of preterm births in 2020, highlighting the urgent need for effective neonatal care. The device, known as Bempu, signals caregivers when a baby's body temperature falls to dangerous levels, helping prevent serious complications. Narain, who was raised in the U.S., dedicated himself to this cause after witnessing the challenges faced by premature infants. His work has gained recognition, being named one of TIME Magazine’s 25 Best Inventions. In interviews, Narain explained that the watch has not only transformed individual cases of neonatal care but has also set a precedent for future healthcare innovations in India. The Bempu watch's impact extends beyond national borders, as its implementation is being explored in various countries to enhance the survival rates of vulnerable newborns.

OpenAI CEO Sam Altman Set to Visit India Amid Growing Competition

Sam Altman, the CEO of Microsoft-backed OpenAI, is reportedly planning a visit to New Delhi on February 5, according to Reuters, citing three sources. This marks his first visit since 2023, when he met Prime Minister Narendra Modi to discuss the prospects of artificial intelligence in India's technology sector. The specifics of Altman's itinerary remain unconfirmed and may vary. The anticipated visit comes as OpenAI faces intensified competition from Chinese AI firm DeepSeek, whose AI Assistant recently surpassed ChatGPT to become the leading free app in the U.S. Apple App Store. Additionally, OpenAI is navigating legal challenges in India, where a lawsuit was filed last year accusing the company of copyright infringements related to news articles. While OpenAI has stated that it utilizes publicly available data under fair use principles, it has yet to issue comments on the ongoing legal matters or Altman's upcoming trip. India has emerged as OpenAI's second-largest market after the U.S., underlining the significance of this visit.

India Successfully Launches Navigation Satellite, Strengthening Space Capabilities

India has successfully launched a regional navigation satellite, NVS-02, aboard its GSLV-F15 rocket from the Satish Dhawan Space Centre in Sriharikota. The launch, which occurred at 6:23 a.m. IST on Wednesday, marks India's 100th space mission, according to the Indian Space Research Organisation (ISRO). The NVS-02 satellite is part of India's Navigation with Indian Constellation (NavIC) system, designed to offer positioning services across India and nearby regions. This development positions NavIC as a competitor to established systems like the U.S. Global Positioning System (GPS), China's BeiDou, and the European Galileo, and is seen as crucial as global competition in satellite technology escalates. Jitendra Singh, India’s Minister of Science and Technology, emphasized the significance of this launch in advancing the country's capabilities in space-based technologies. Amid increased international rivalry in the space sector, ISRO aims to conduct 30 missions by March 2025, reflecting India's growing role in the global space arena.
