30-Foot ‘Doomsday Fish' Caught In Tamil Nadu, Folklore Ties It To Earthquakes, Tsunamis
A rare deep-sea fish, known as the ' Pralaya fish ' or Oarfish (Regalecus glesne), was recently caught in fishermen's nets off the coast of Tamil Nadu. This silver-shining, ribbon-like fish, which can grow up to 30 feet long and has a red fin on its head, typically dwells at depths of 200 to 1,000 metres. Its appearance on the surface has sparked both curiosity and concern among local residents.
A report by the Times of India suggests that the sighting of an oarfish near coastal regions has long been believed to signal impending doom, such as a natural disaster. The recent discovery of an oarfish in Tamil Nadu has revived these fears, as its appearance is often linked to catastrophic events, prompting speculation about a possible connection between this fish and such disasters.
In Japanese and Filipino folklore, the oarfish is believed to be a harbinger of natural disasters such as earthquakes and tsunamis, a belief that has earned it the name 'Doomsday fish'. This latest sighting occurred on May 30, 2025, when Tamil Nadu fishermen captured the giant fish, and its video quickly went viral on social media.
The fish's shiny, snake-like appearance and distinctive red fins were clearly visible, causing alarm among locals who connected the event to Japanese folklore, specifically ' Ryugu no Sukai ' (messenger of the god of the sea).

Historical reports have noted the sighting of 20 oarfish prior to the 2011 Tohoku earthquake and tsunami in Japan, as well as two oarfish before a 6.6 magnitude earthquake in the Philippines in 2017, reinforcing the belief that the presence of oarfish at the surface signals impending disaster.
The Times of India report suggests that previous encounters with oarfish have often been associated with tragic events, leading locals to view the fish as a harbinger of doom.
For instance, in Mexico, an oarfish was discovered on the shore just before a significant earthquake struck. This perceived connection between the oarfish and disasters has earned it the nickname 'Doomsday Fish" and sparked growing curiosity about its behavior.
However, scientific evidence does not support this theory. A 2019 study published in the 'Bulletin of the Seismological Society of America' found no concrete link between oarfish sightings and earthquake events from 1928 to 2011. Researcher Yoshiaki Orihara stated, 'There is no clear link between the sighting of oarfish and earthquakes."
Scientists suggest that oarfish may surface due to natural reasons such as changes in ocean currents, temperature fluctuations, or illness. For instance, a 2018 study indicated that climate events like El Niño, which cause higher-than-normal ocean temperatures, can bring oarfish to shallower waters. Marine biologist Thomas Claverie explained that while the sighting of oarfish is rare, it is not always associated with disasters. 'Fishermen see it from time to time, and it is not like there is a tsunami every time," he said.
Some experts theorise that subtle pressure changes from deep-sea seismic activity might push the fish to the surface, though this remains unproven. Additionally, oarfish often surface when they are sick or dying. According to the Scripps Institution of Oceanography, only 20 oarfish were seen in California from 1901 to 2024, most of which were dead.
The recent incident in Tamil Nadu has ignited a debate on social media. While some users believe the fish is a warning of disaster, others consider it a natural phenomenon. One post noted, 'The sighting of oarfish in Tamil Nadu coincided with heavy monsoon but has no connection with the disaster." Although Tamil Nadu recently experienced heavy rainfall, no direct link to the oarfish was found.
This event not only highlights the enigmatic nature of the oarfish but also underscores the growing human impact on marine ecosystems. Factors like plastic pollution and climate change are affecting deep-sea creatures, making it crucial to preserve the ocean for species like the oarfish.

Cancer Breakthrough In Britain: Patients Discharged Within Minutes Of Injection
This saves patients hours annually, time they can spend with family, at work, or relaxing, while also offering major psychological relief from spending less time in hospitals With scientific advancements, cancer treatment has made significant progress. Several modern therapies are now available, making it possible to treat even advanced stages of the disease. While a complete cure for cancer is still elusive, many cases can now be effectively managed. One such advanced treatment is immunotherapy, which is typically administered through a drip that takes one to two hours. In a major breakthrough for cancer care, the UK National Health Service (NHS) has introduced a faster, more efficient way to deliver immunotherapy. Patients receiving the drug Nivolumab, used in the treatment of various cancers, can now get it via a quick injection that takes just 1 to 5 minutes. Until now, the same treatment required an hour-long IV drip, marking this shift as a significant step toward improving comfort and reducing time spent in hospitals. According to a Times of India report, Nivolumab is a type of immunotherapy that enhances the body's immune response against cancer cells. While the drug itself is not new, the method of delivery represents a significant improvement. This change is expected to have profound effects on cancer treatment, offering substantial benefits not only medically but also emotionally and practically for thousands of patients. This improvement can save patients dozens of hours annually, time that can be spent with family, at work, or relaxing at home. The psychological benefits of less time in hospital and more time in life are considerable. The new injection system also provides substantial advantages for the NHS, potentially saving around 1,000 hours each month, which can be reallocated to care for more patients, better manage appointments, and reduce waiting times. For many, this injection represents not just a medical advancement but a means to maintain a better routine and lead a less burdensome life. According to the Times of India report, the new injectable form of the immunotherapy drug Nivolumab has been approved for use in treating 15 different types of cancer, including skin, bladder, and oesophageal cancers. This quicker treatment method is expected to benefit nearly 1,200 patients in England every month, covering both new patients and those already on IV-based Nivolumab. Roughly 40% of existing IV recipients could shift to this injection-based option, which takes just 1 to 5 minutes to administer—compared to the hour-long IV sessions. Though not suitable for every patient, for those who qualify, the shorter and simpler process is a significant relief, medically and emotionally. Clinical trials have shown the injection to be equally effective as the IV form, with most patients reporting higher comfort and convenience. In fact, many preferred the injection over traditional drips, citing both time saved and less physical strain. Notably, this advancement comes at no additional cost. The NHS has successfully negotiated pricing with the drug manufacturer to ensure that the faster treatment does not put extra pressure on healthcare budgets. This aligns with the NHS's broader push toward more efficient, patient-friendly medical solutions that also make better use of limited resources. view comments Disclaimer: Comments reflect users' views, not News18's.

Is population decline good for nature? Japan shows that may not be the case
Since 1970, 73% of global wildlife has been lost, while the world's population has doubled to 8 billion. Research shows this isn't a coincidence but that population growth is causing a catastrophic decline in biodiversity. Yet a turning point in human history is underway. According to UN projections, the number of people in 85 countries will be shrinking by 2050, mostly in Europe and Asia. By 2100, the human population is on course for global decline. Some say this will be good for the environment. In 2010, Japan became the first Asian country to begin depopulating. South Korea, China and Taiwan are following close behind. In 2014, Italy was the first in southern Europe, followed by Spain, Portugal and others. We call Japan and Italy 'depopulation vanguard countries' on account of their role as forerunners for understanding possible consequences in their regions. Given assumptions that depopulation could help deliver environmental restoration, we have been working with colleagues Yang Li and Taku Fujita to investigate whether Japan is experiencing what we have termed a biodiversity ' depopulation dividend ' or something else. Since 2003, hundreds of citizen scientists have been collecting biodiversity data for the Japanese government's Monitoring Sites 1,000 project. We used 1.5 million recorded species observations from 158 sites. These were in wooded, agricultural and peri-urban (transitional spaces on outskirts of cities) areas. We compared these observations against changes in local population, land use and surface temperature for periods of five to 20 years. Our study, published in the journal Nature Sustainability, includes birds, butterflies, fireflies, frogs and 2,922 native and non-native plants. These landscapes have experienced the greatest depopulation since the 1990s. Due to the size of our database, choice of sites and the positioning of Japan as a depopulation vanguard for north-east Asia, this is one of the largest studies of its kind. Japan is not Chernobyl Biodiversity continued to decrease in most of the areas we studied, irrespective of population increase or decrease. Only where the population remains steady is biodiversity more stable. However, the population of these areas is ageing and will decline soon, bringing them in line with the areas already seeing biodiversity loss. Unlike in Chernobyl, where a sudden crisis caused an almost total evacuation which stimulated startling accounts of wildlife revival, Japan's population loss has developed gradually. Here, a mosaic pattern of changing land use emerges amid still-functioning communities. While most farmland remains under cultivation, some falls into disuse or abandonment, some is sold for urban development or transformed into intensively farmed landscapes. This prevents widespread natural succession of plant growth or afforestation (planting of new trees) that would enrich biodiversity. In these areas, humans are agents of ecosystem sustainability. Traditional farming and seasonal livelihood practices, such as flooding, planting and harvesting of rice fields, orchard and coppice management, and property upkeep, are important for maintaining biodiversity. So depopulation can be destructive to nature. Some species thrive, but these are often non-native ones that present other challenges, such as the drying and choking of formerly wet rice paddy fields by invasive grasses. Vacant and derelict buildings, underused infrastructure and socio-legal issues (such as complicated inheritance laws and land taxes, lack of local authority administrative capacity, and high demolition and disposal costs) all compound the problem. Even as the number of akiya (empty, disused or abandoned houses) increases to nearly 15% of the nation's housing stock, the construction of new dwellings continues remorselessly. In 2024, more than 790,000 were built, due partly to Japan's changing population distribution and household composition. Alongside these come roads, shopping malls, sports facilities, car parks and Japan's ubiquitous convenience stores. All in all, wildlife has less space and fewer niches to inhabit, despite there being fewer people. What can be done Data shows deepening depopulation in Japan and north-east Asia. Fertility rates remain low in most developed countries. Immigration provides only a short-term softer landing, as countries currently supplying migrants, such as Vietnam, are also on course for depopulation. Our research demonstrates that biodiversity recovery needs to be actively managed, especially in depopulating areas. Despite this there are only a few rewilding projects in Japan. To help these develop, local authorities could be given powers to convert disused land into locally managed community conservancies. Nature depletion is a systemic risk to global economic stability. Ecological risks, such as fish stock declines or deforestation, need better accountability from governments and corporations. Rather than spend on more infrastructure for an ever-dwindling population, for example, Japanese companies could invest in growing local natural forests for carbon credits. Depopulation is emerging as a 21st-century global megatrend. Handled well, depopulation could help reduce the world's most pressing environmental problems, including resource and energy use, emissions and waste, and nature conservation. But it needs to be actively managed for those opportunities to be realised.

Vector-Borne Diseases During Monsoon: Preventive Measures You Must Follow
Vector-borne diseases are illnesses transmitted by vectors living organisms like mosquitoes, ticks, and flies that carry and spread pathogens such as viruses, bacteria, or parasites. During the monsoon season, stagnant water and increased humidity create ideal breeding conditions for disease-carrying insects, especially mosquitoes. This leads to a spike in diseases like dengue, malaria, chikungunya, and Japanese encephalitis. Fortunately, most vector-borne diseases are preventable through proactive measures, such as eliminating mosquito breeding grounds, using protective barriers, and maintaining hygiene. Keep reading as we share a list of preventive measures you can follow this monsoon to stay healthy. Preventive measures for vector-borne diseases during monsoon 1. Avoid stagnant water near your home Mosquitoes breed in stagnant water found in flower pots, buckets, clogged drains, and water coolers. Regularly check and empty these sources to stop mosquito breeding at its root. 2. Use mosquito nets and screens Sleeping under mosquito nets and installing mesh screens on doors and windows create a physical barrier, protecting you from mosquito bites, especially during the night when many disease-carrying mosquitoes are most active. 3. Apply mosquito repellents Use topical creams, sprays, or patches containing DEET, picaridin, or eucalyptus oil on exposed skin. These repellents keep mosquitoes at bay and reduce the chances of being bitten, especially when outdoors. 4. Wear full-sleeved clothing Wearing long-sleeved shirts, full pants, and socks, especially during dawn and dusk when mosquitoes are most active, minimises exposed skin and provides an extra layer of protection. 5. Keep surroundings clean and dry Eliminate garbage buildup, clean drains regularly, and ensure there is no water accumulation in your locality. A clean environment reduces breeding grounds for not just mosquitoes but other disease-carrying vectors too. 6. Use insecticides and fumigation Spray insecticides in dark corners, under furniture, and around stagnant water areas. Community-level fumigation can also help in reducing the mosquito population, especially during peak monsoon. 7. Ensure proper water storage If you store water for daily use, make sure containers are tightly covered and cleaned regularly. Uncovered containers are prime mosquito breeding sites, especially in urban and rural homes. 8. Avoid walking in floodwaters Flooded streets during monsoon can expose you to leptospirosis and other infections. If unavoidable, wear waterproof footwear and clean your feet thoroughly afterward. 9. Boost immunity through nutrition Eating a balanced diet rich in fruits, vegetables, and vitamin C can strengthen your immune system, making it easier for your body to fight off infections if exposed. 10. Seek early medical attention for symptoms If you experience high fever, chills, joint pain, rashes, or fatigue, common symptoms of vector-borne diseases consult a doctor immediately. Early diagnosis and treatment prevent complications and stop the disease from spreading further. Being alert and consistent with prevention can drastically reduce the risk of infection during the rainy season. Disclaimer: This content including advice provides generic information only.
