Cocaine in Brazilian Sharpnose Sharks: Alarming Levels Found in South America’s Coastal Waters

In a surprising and concerning discovery, researchers in Brazil have found significant levels of cocaine and its metabolites in the system of Brazilian sharpnose sharks (Rhizoprionodon lalandii) swimming in South America's coastal waters. This finding, spearheaded by environmental scientist Gabriel de Farias Araujo from the Oswaldo Cruz Institute, underscores the pervasive issue of pharmaceutical pollution affecting marine life. The research team tested 13 juvenile and young adult Brazilian sharpnose sharks, finding high concentrations of cocaine in all of them. Additionally, the drug's main metabolite, benzoylecgonine, was present in all but one shark. These findings are particularly alarming given that these predators play a crucial role in the marine food chain. While Hollywood mi...

Death Toll in Ethiopian Landslides Rises to 229 Search for Survivors Continues

Breaking News, Disasters

The death toll from two devastating landslides in southern Ethiopia has surged to 229, with the number expected to rise further as rescue efforts continue, a government official reported on Tuesday. Triggered by heavy rainfall, the first landslide occurred in the Gofa zone of Southern Ethiopia's regional state on Sunday night, burying numerous residents. A second landslide struck on Monday morning, engulfing many who had gathered to assist in rescue operations. "I don't know when it will stop. We are still recovering bodies," said Markos Melese, head of the National Disaster Response agency in Gofa Zone, in a phone interview with Reuters. "We are still digging." Initially, officials reported at least 50 fatalities, including children and police officers. However, the toll has esca...

Impact of the Teesta Valley GLOF: Photo Feature on Krishnagram – A Sinking Zone in Teesta Bazar

Breaking News, Disasters

In a poignant revisit to Krishnagram, a sinking zone in the Teesta Bazar, the devastation wrought by the October 2023 Glacial Lake Outburst Flood (GLOF) remains starkly evident. Documented by Junkeri Studio in collaboration with SaveTheHills, this photo feature highlights the ongoing crisis faced by the residents of this beleaguered area. Bhasuwa Renamed Krishnagram: A Submerging Reality Coordinates: 27°03'41.7"N, 88°25'29.2"E, Elevation 248m Formerly known as Bhasuwa, Krishnagram has experienced a dramatic increase in subsidence since the GLOF raised the Teesta river levels by 4-5 meters. The river now flows perilously close, exacerbating erosion and ground instability. Desperation Amidst Destruction Ganga Sarki's Plight Mrs. Ganga Sarki, 55, and her paralyzed elder brot...

Fiber Optic Cables: The Future of Earthquake Detection

Breaking News, Disasters

Submarine communication cables, like the intricate network branching off from Japan, illustrate our planet's interconnectedness. These cables, with their colorful lines connecting Japan’s islands to the rest of the world, are not only vital for data transmission but may also be key to detecting natural disasters. Innovative Use of Existing Infrastructure Dr. Tonegawa and his team highlight the potential of Distributed Acoustic Sensing (DAS) technology, which could transform submarine cables into extensive seismic monitoring networks. DAS offers two major advantages over traditional seismic tools: Governments and companies globally have already laid about 1.4 million kilometers of submarine cables. Although DAS cannot be applied along the entire length of these cables, collaborat...

Discovery of Intermediate Mass Black Hole in IRS 13 Offers Vital Clues to Black Hole Evolution

Breaking News, Learning & Developments, Space

In a breakthrough that could significantly advance our understanding of black hole evolution, astronomers have identified a potential intermediate mass black hole within the star cluster IRS 13 near the Milky Way's core. This discovery, only 0.1 light-years from the supermassive black hole Sagittarius A* (Sgr A*), offers critical insights into the missing link between stellar mass black holes and their supermassive counterparts. Intermediate mass black holes, those with masses between 100 and 100,000 solar masses, are exceedingly rare. Their scarcity has left a puzzling gap in the evolutionary chain of black holes, which ranges from stellar mass black holes (up to about 80 solar masses) to supermassive black holes (millions to billions of solar masses). The detection of an intermediate ...

Cooling Urban Heat Islands: New Study Highlights the Role of Surrounding Countryside

Breaking News, Climate Actions

Scientists at the University of Surrey's Global Centre for Clean Air Research (GCARE) and Southeast University (China) have discovered that cooling "urban heat islands" may depend significantly on the surrounding rural areas. The study, which analyzed 20 years of data, reveals that rural regions can effectively reduce city temperatures, especially when the rural ring around a city extends for at least half the city's diameter. Urban heat islands, characterized by significantly higher temperatures in city centers compared to their rural surroundings, are a growing concern as global temperatures rise. Traditional approaches to mitigate these effects have focused on integrating green spaces, wetlands, and waterways within urban areas. However, the scarcity of urban land makes these measure...

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 ...
