Earthquakes May Play a Key Role in the Formation of Gold Nuggets, Study Reveals

A groundbreaking study has revealed that earthquakes might significantly contribute to the formation of gold nuggets within quartz veins through a process called piezoelectricity. This discovery challenges the traditional understanding of how gold forms, offering new insights into the geological processes that create this precious metal. Gold, long prized for its rarity and beauty, is typically found as nuggets embedded in quartz veins, a form of crystallized silicon dioxide. While the conventional explanation has been that gold precipitates from hot, water-rich fluids moving through cracks in the Earth's crust, the new study suggests that seismic activity could play a crucial role. The research, titled "Gold Nugget Formation from Earthquake-Induced Piezoelectricity in Quartz," was r...

Global Flooding Hazards Projected to Surge by 49% by 2100: New Study Warns

Breaking News, Disasters, Idea & Innovations

A new study warns that global flooding hazards are set to increase by 49% between 2020 and 2100 if greenhouse gas emissions continue unabated. The research, published in Water Resources Research, highlights the regions most at risk, including the coasts of the North Atlantic, Indian Ocean, southeastern Asia, and the Pacific Islands. The study utilized advanced modeling techniques to create a Global Flood Map (GFM), which considers floods induced by rainfall, river discharge, and rising sea levels. The research team, led by Professor Paul Bates from the University of Bristol Cabot Institute for the Environment, noted that previously used flood maps lacked accuracy in simulating real floods. By applying new techniques, the team gained more precise insights into future flood risks. The ...

Ganga Rivers has Likely Altered their Course due to the mega earthquake occured in 2,500 Years Ago: New Study Reveals

Breaking News, Disasters, Environment, Idea & Innovations

In a groundbreaking discovery, researchers have revealed that an earthquake approximately 2,500 years ago may have caused the Ganga River to abruptly change its course. This seismic event, which was previously undocumented, is believed to have been of a magnitude 7-8 and could have significantly altered the landscape of present-day Bangladesh. The study, published in the journal Nature Communications, suggests that the earthquake was powerful enough to reroute the main channel of the Ganga, one of the most significant rivers in the world. The Ganga, which originates in the Himalayas, eventually merges with other major rivers, including the Brahmaputra and the Meghna, before flowing into the Bay of Bengal. This river system forms the world’s second-largest delta, surpassed only by the Am...

Researchers Propose New Definition for Planets Potentially Reclassifying Celestial Bodies Across the Universe

Breaking News, Idea & Innovations

A recent study published in The Planetary Science Journal proposes a new definition of a "planet" that could challenge the longstanding criteria established by the International Astronomical Union (IAU). The team of researchers from the United States and Canada, led by Dr. Jean-Luc Margot from the University of California, Los Angeles, aims to address the issues with the current IAU Resolution B5, which was established in 2006 and led to the demotion of Pluto from a planet to a dwarf planet. The current IAU definition requires a celestial body to orbit the Sun, be nearly round in shape, and have cleared its orbit of other debris. This definition, however, excludes exoplanets and is considered vague by many in the scientific community. Dr. Margot and his team argue that a more quantitati...

Oak Ridge National Laboratory’s Advanced 3D Modeling Framework for Predicting Flood Risks

Breaking News, Disasters, Idea & Innovations

Scientists at the Department of Energy's Oak Ridge National Laboratory (ORNL) have developed a cutting-edge 3D modeling framework to predict long-term flooding risks by capturing the intricate dynamics of water flow across landscapes. This tool is designed to provide crucial insights into community vulnerabilities as climate conditions change, specifically for urban areas like Southeast Texas. Framework Overview The model offers powerful capabilities for urban planning, generating robust estimates of both frequent and rare flood events by simulating physical processes that turn rainfall into runoff. By incorporating factors such as land cover, soil properties, and land slope, along with population density data, the framework provides a comprehensive perspective on flood risks across ...

Researchers Develop Advanced AI Model for Accurate Typhoon Prediction

Breaking News, Climate Actions, Idea & Innovations

In a significant advancement for climate science, a team of researchers from the Department of Civil, Urban, Earth, and Environmental Engineering at the Ulsan National Institute of Science and Technology (UNIST), led by Professor Jungho Im, has developed a pioneering deep learning-based model for predicting tropical cyclones (TCs). Their findings have been published in GIscience & Remote Sensing and iScience in March and May 2024, respectively. The newly developed Hybrid-Convolutional Neural Networks (Hybrid-CNN) model integrates real-time geostationary weather satellite data and numerical prediction model outputs to forecast TC intensity with lead times of 24, 48, and 72 hours. This approach offers a significant improvement over traditional methods, which often suffer from lengthy ...

Why Does Delhi Flood? The Answer Lies in Our Urban Stormwater Management

Breaking News, Disasters, Idea & Innovations

Every year, we witness flooding in our large metropolises and most state capitals. Normally, Delhi is in the news for flooding due to the overflowing of the Yamuna River when large volumes of water are released from the Tajewala dam upstream. However, on June 28, 2024, we witnessed flooding from a high rainfall episode in south Delhi. What explains the frequent in-situ urban flooding in Delhi? This happened in Bengaluru and Lucknow in 2023 as well. High rainfall and climate change are undoubtedly a reality. But is it just that, or something more? To understand the recent flooding in Delhi, let us first understand why 15 minutes of rainfall causes flooding on the Mehrauli-Badarpur road (MB Road) in south Delhi. What does this have to do with understanding Delhi’s urban stormwater managem...

New Study Reveals Ancient Origins of LUCA Early Life on Earth

Breaking News, Climate Actions, Idea & Innovations

Once upon a time, Earth was a barren planet. That changed dramatically when, out of the chemistry present during its early history, something began to squirm processing matter to survive, reproduce, and thrive. The nature of that something, and when it first appeared, have puzzled humanity for as long as we have been able to ask, "What am I?" Now, a groundbreaking study has provided some answers, revealing that life emerged surprisingly early in Earth's history. By analyzing the genomes of organisms alive today, scientists have determined that the last universal common ancestor (LUCA) the first organism that spawned all current life on Earth emerged as early as 4.2 billion years ago. Given that Earth is around 4.5 billion years old, this suggests that life began when the planet was s...

NASA’s Habitable Worlds Observatory Aiming to Detect Alien Life on Earth Like Planets by 2050

Breaking News, Idea & Innovations, Space

NASA is gearing up to launch the Habitable Worlds Observatory (HWO), a state-of-the-art telescope designed specifically to search for signs of extraterrestrial life on Earth-like planets. Scheduled to launch by 2040, HWO represents a monumental step in the quest to find habitable planets by 2050. Dr. Jessie Christiansen, NASA’s chief scientist for the search for extraterrestrial life, has expressed optimism that HWO will detect signals from planets within the habitable zones of sun-like stars during our lifetime. The primary objective of the observatory is to identify biosignatures, which are indicators of life, such as biogenic gases, aerosols, surface biosignatures, and even technosignatures from advanced civilizations. To date, NASA has pinpointed twenty-five Earth-like planets or...
