    India has confirmed its first scientifically verified case of pufferfish poisoning, bringing national attention to a long-overlooked public health risk linked to freshwater ecosystems. The case highlights how toxic wildlife, microbial dynamics and gaps in food safety awareness intersect in India’s riverine regions, placing unsuspecting communities at risk. The incident involved a 23-year-old man from Veraval in Gujarat, who developed sudden numbness, vomiting and rapidly worsening paralysis shortly after consuming a low-cost freshwater fish purchased from a local village market. Medical examination and scientific evaluation later confirmed that the symptoms were caused by tetrodotoxin, a powerful neurotoxin associated with certain species of pufferfish. This confirma...

    Lake Natron, located in northern Tanzania near the Kenyan border, is one of the most visually striking and scientifically fascinating water bodies in the world. Known for its deep red colour and highly alkaline waters, the lake has earned global attention for its ability to preserve dead animals in a stone-like state while simultaneously supporting one of the largest breeding grounds for lesser flamingos. The lake’s dramatic red hue is caused by high concentrations of salt, minerals, and salt-loving microorganisms, particularly haloarchaea and cyanobacteria. These organisms thrive in extreme environments and produce red pigments that intensify as water levels drop and temperatures rise. During dry seasons, the lake can appear almost blood-red from aerial views. La...

    In villages across Ladakh, a quiet but telling transformation is underway. Traditional mud roofs, long designed to endure one of the harshest winters on the planet, are being replaced by steel sheets. At first glance, this appears to be a practical response to changing weather. In reality, the rise of steel roofing reveals a deeper crisis shaped by climate change, development pressures and a profound shift in Ladakh’s social world. When residents returned to their villages after the unprecedented rainfall of August, the damage was unmistakable. Leh alone recorded nearly 80 millimetres of rain, an almost tenfold increase over its historical average. For generations, flat mud roofs had been perfectly suited to Ladakh’s climate, which received most of its precipitation ...

    As Indian cities grow denser and hotter, urban forests are increasingly being promoted as a solution to rising temperatures. But evidence from cities such as Chennai suggests that trees alone are not a universal fix. Urban forests can help cool cities and improve quality of life, but only when planners understand local climate conditions, ecological systems and how people use urban land. Chennai, a coastal city of 4.5 million people, routinely experiences summer temperatures touching 44 degrees Celsius. Despite its cultural richness, with hundreds of temples and a national park embedded within the city, Chennai has limited shaded public spaces. Trees line some roads, but large green parks are scarce, leaving much of the city exposed to extreme heat. As urbanisatio...

    Large parts of India are experiencing unusually cold conditions in the opening weeks of 2026, with temperatures dipping well below seasonal norms across east, central and southern regions. Meteorologists are now closely monitoring the possibility of a rare and intense cold blast affecting north India later this month, potentially driven by an Arctic-origin weather system. The cold spell, which began in December 2025 in several regions, has intensified in early January. On January 12, multiple locations across the plains of northwest India recorded sub-zero or near-zero minimum temperatures. The outskirts of Gurgaon reported temperatures close to minus one degree Celsius, while Fatehpur Shekawati in Rajasthan recorded a low of minus 3.5 degrees Celsius on January 11. ...

    Hidden beneath forest floors, inside rotting wood, across deserts, caves and even near the summit of Mount Everest, lives one of Earth’s most ancient and important groups of animals springtails. These tiny invertebrates, largely unknown outside scientific circles, have been quietly shaping the health of the planet’s ecosystems for more than 400 million years. Springtails, scientifically known as Collembola, evolved alongside mosses and lichens long before dinosaurs roamed the Earth. Today, they are found on every continent, including Antarctica, thriving in environments ranging from humid rainforests and mangroves to frozen polar soils and underground caves nearly 2,000 metres deep. Despite their insect-like appearance, springtails are not insects. They lack wings...

    The recent deaths of at least 21 people in Indore after consuming contaminated tap water have once again highlighted the deep-rooted weaknesses in India’s urban water supply systems. Preliminary investigations indicate that leakages in the city’s drinking water pipeline allowed sewage to enter the supply, a problem that officials say is linked to ageing infrastructure and the close proximity of water and sewerage lines underground. Such incidents are not isolated. Cities like Bengaluru have also reported repeated contamination scares, despite years of investment in urban water infrastructure. Experts argue that the core issue lies in India’s dependence on intermittent water supply systems, where water flows for only a few hours a day. These systems, they say, are str...

    Scientists studying fossil remains in eastern China have uncovered a rare and puzzling discovery: two nearly spherical dinosaur eggs that contain no traces of embryos or bones, but are instead filled with large mineral crystals. The finding offers fresh insight into how fossilisation can occur under unusual geological conditions and sheds light on the environment during the final years of the dinosaurs. The eggs were discovered in the Qianshan Basin of Anhui Province, an area known for preserving Late Cretaceous fossils. Measuring about 13 centimetres in diameter, the eggs were remarkably well preserved on the outside. However, when researchers examined their interiors, they found hollow chambers lined with clusters of calcite crystals rather than organic remains. ...

    Delhi-NCR residents woke up on Makar Sankranti, January 14, 2026, expecting a familiar winter scene of lingering cold, routine fog and sluggish traffic. Instead, the capital witnessed an unusual and dramatic weather event that unfolded within minutes and vanished just as quickly. Between 7:45 am and 8 am, a dense curtain of fog suddenly enveloped large parts of Delhi and its surrounding regions, reducing visibility to almost zero. Roads, flyovers and railway tracks disappeared under a thick white haze, leaving commuters stunned. What made the event striking was its brevity. Within a short span, the fog began to thin and dissolve, restoring visibility almost as suddenly as it had vanished. This was not the typical overnight fog that blankets north India during wint...
