    Delhi woke up to a blanket of smog on Saturday as air quality across the national capital region deteriorated sharply, pushing the Air Quality Index back into the ‘very poor’ category and disrupting daily life. After a brief improvement earlier in the week, pollution levels began rising again on December 26, with the city recording an AQI of 333, according to official data. By 11:05 am on December 27, the average AQI stood at 359, placing it firmly in the ‘very poor’ range. Several monitoring stations reported even worse conditions, with some slipping into the ‘severe’ category. The primary pollutants driving the decline were fine particulate matter PM2.5 and PM10, which pose serious health risks, especially for children, the elderly and people with respiratory condi...

    Tiny plastic particles that are now everywhere in daily life may be doing far more damage to the heart than previously believed. A new study from the University of California, Riverside has found that microplastics can burrow into blood vessels and dramatically accelerate the development of heart disease, at least in male mice. The findings suggest that microplastics may actively damage arteries rather than simply being passive contaminants found alongside disease. Microplastics are released from everyday items such as food packaging, synthetic clothing, and disposable plastic products. They have already been detected in human blood, organs, and even inside arterial plaques. Until now, scientists were unsure whether these particles played a direct role in cardiovascu...

    NEW DELHI: Delhi woke up to a toxic mix of severe air pollution and dense fog on Monday, pushing the city’s Air Quality Index past the 400 mark and severely disrupting flight operations across northern India. The deteriorating conditions prompted the Ministry of Civil Aviation and multiple airlines to issue travel advisories, warning passengers of possible delays and cancellations. According to data from the Central Pollution Control Board (CPCB), Delhi’s AQI stood at 402 at 8 am, placing it firmly in the ‘severe’ category. This marked a sharp decline from Sunday evening, when the AQI was recorded at 390 and classified as ‘very poor’. Several parts of the capital reported even worse conditions, with Anand Vihar registering an alarming AQI of 455, followed by Wazirpur...

    In a major scientific breakthrough, researchers have successfully recovered RNA from an extinct animal for the first time, allowing them to study which genes were active when the animal was alive. The achievement was made using tissue from the Tasmanian tiger, or thylacine, which went extinct nearly 90 years ago. The research was led by Dr. Marc R. Friedländer of Stockholm University in Sweden and published in the journal Genome Research. The team analysed skin and muscle samples taken from a 130-year-old thylacine specimen preserved in a Swedish museum. The animal had been stored dry at room temperature since the late 19th century, conditions once thought unsuitable for RNA preservation. DNA reveals what genes an organism possesses, but RNA shows how those genes ...

    After more than three decades, Gujarat has officially regained its status as a ‘tiger-present’ state, marking a major milestone in wildlife conservation. The National Tiger Conservation Authority (NTCA) has confirmed the presence of a tiger in the state, Deputy Chief Minister Harsh Sanghavi announced on Friday. With this confirmation, Gujarat has become home to all three major big cats found in India the Asiatic lion, leopard and tiger a rare and significant ecological distinction. According to forest department records, tigers had gone extinct in Gujarat in 1989, nearly 36 years ago. The development follows the Gujarat Forest Department’s announcement last month that a wandering tiger had settled in the Ratanmahal Wildlife Sanctuary in Dahod district. Continuous ...

    A remarkable discovery made by an 11-year-old girl during a simple beach walk has led scientists to identify what may be the largest marine reptile ever to have lived on Earth. The finding is now reshaping scientific understanding of prehistoric oceans and the true size of ancient marine predators. The fossil, a massive lower jawbone measuring more than two metres in length, was discovered in 2020 on the coast of Blue Anchor in Somerset, southwest England. The bone was found by schoolgirl Ruby Reynolds and her father while fossil hunting along the shoreline. Scientists later confirmed that it belongs to a previously unknown species of giant ichthyosaur, now named Ichthyotitan severnensis. Researchers determined that the newly identified species lived around 202 mi...

    Soft-eyed, smiling, and famously friendly, the Irrawaddy dolphin has long been known as one of the world’s sweetest animals. Found in the rivers and coastal waters of Southeast Asia, this rare dolphin is not just a marine species but a living symbol of harmony between humans and nature. Today, however, it stands at the edge of extinction, with fewer than 100 individuals surviving in several key river systems. For generations, Irrawaddy dolphins have shared a unique bond with fishing communities in countries such as Myanmar, Cambodia, and Indonesia. Along rivers like the Ayeyarwady, fishing begins not with nets, but with trust. Fishermen gently tap their boats, waiting quietly. Soon, the dolphins appear, guiding schools of fish toward the nets. In return, they feed on...

    For more than 100 years, fingerprint identification has been treated as an unshakable pillar of forensic science. Courts, police forces, and investigators across the world have relied on one core assumption: no two fingerprints are the same, not even among the ten fingers of a single person. A new artificial intelligence study now suggests that this belief may no longer hold true. A peer-reviewed study published in Science Advances has revealed that fingerprints taken from different fingers of the same individual can share hidden similarities that traditional forensic methods fail to detect. These similarities are invisible to the human eye but can be identified using advanced deep-learning systems, raising serious questions about how fingerprint evidence is interpre...

    In a rare and striking climate event, Saudi Arabia witnessed snowfall for the first time in nearly three decades, while Iceland recorded unusually high temperatures close to 20 degrees Celsius on Christmas night. The contrasting weather patterns unfolding thousands of kilometres apart have left scientists and residents alike stunned. People across parts of northern Saudi Arabia woke up to snow-covered deserts and mountains, a sight many locals said they were seeing for the first time in their lives. Regions such as Jabal Al Lawz and the Trojena highlands experienced sub-zero temperatures, with mercury dropping to around minus four degrees Celsius at elevations of nearly 2,600 metres. Snow settled across normally dry landscapes, transforming the terrain into a white e...

    Jharkhand could play a decisive role in India’s journey towards net-zero emissions by transforming its vast mining landscape into hubs of green growth, according to a new study by the International Forum for Environment, Sustainability and Technology (iFOREST). The report highlights how the mineral-rich state can turn environmental challenges into long-term economic opportunities through strategic planning and clean investments. The study points out that nearly 45,000 hectares of mining land in Jharkhand can be repurposed into productive assets, supporting renewable energy projects, green manufacturing and low-carbon industries. With more than ₹51,000 crore accumulated under the District Mineral Foundation, the state already has substantial financial resources to sup...
