PCB & citizens join hands to examine Dighalipukhuri water
Led by PCB's chief environmental scientist Gautam Kumar Mishra, the team sampled multiple points in the tank to measure chemical and bacterial contamination levels. "This comprehensive approach will give a clear picture of the water body's current state and guide targeted restoration measures," Mishra said.
Mishra said water samples are collected from time to time, the data is studied thoroughly to assess the situation.
According to PCB's National Water Monitoring Programme (NWMP) data from Jan, Dighalipukhuri's water is slightly alkaline (pH 8.2) and contains high dissolved oxygen (9.9 mg/l), which supports aquatic life. However, the water is unsafe for direct human use without treatment. Moderate levels of phosphate and ammonia may also promote algal growth, the official said.
Speaking at a morning gathering in Dighalipukhuri park, Delhi-based environmental consultant Prarthana Borah emphasised the importance of the need for nature-led recovery.

"It is now widely accepted that natural ecosystems can regenerate without human interference. Communities should focus on removing the sources of contamination rather than adapting to polluted conditions," she said.
Borah also emphasised the need for involving local experts in such environmental initiatives and highlighted the role of science and leadership — whether governmental or community-driven — in environmental action. She cited the Indore model as a benchmark example of successful municipal and community collaboration in environmental management.

6 science-backed ways to reverse fatty liver, before it's too late
With non-alcoholic fatty liver disease (NAFLD) affecting a significant portion of adults, experts suggest adopting lifestyle changes for liver health. Reducing sugar intake, incorporating intermittent fasting, and increasing physical activity are crucial. A diet rich in protein and fiber, while avoiding refined carbs, alongside weight loss, can significantly improve liver function and reverse NAFLD, emphasizing the importance of early intervention. Fatty liver disease has emerged as a global health concern today. Studies suggest that about 32% of adults have non-alcoholic fatty liver disease (NAFLD). The disease is reported more among men (40%), when compared to women (26%). If caught early, NAFLD can often be reversed. Here are seven evidence-based strategies to restore liver health. Say no to sugar Excess sugar is the biggest enemy of your liver. When you consume too much sugar, especially fructose (found in table sugar and high-fructose corn syrup), your liver has to process it. Over time, too much fructose overwhelms the liver, leading to fat buildup in the liver. It can also cause inflammation and liver damage. Excess sugar intake increases insulin resistance, which can worsen liver health and increase risk of type 2 diabetes. Cutting back on sugar, even for a month, can reduce liver fat significantly. To protect your liver, eliminate sodas, fruit juices, candied fruits, and foods that contain high-fructose corn syrup. Instead, opt for whole fruits in moderation to satisfy sweet cravings without overloading the liver. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Find your most suitable hearing aid Amplifon Book Now Undo Incorporate intermittent fasting Intermittent fasting, where you eat food within an 8–10-hour window, followed by 14–16 hours of fasting, can be beneficial for the liver. This approach triggers autophagy, the body's process of clearing damaged cells, which supports liver health. Changes such as eating an early dinner can improve liver function. Studies have found that intermittent fasting positively affects NAFLD through a number of different physiological pathways. These include improved insulin sensitivity and glucose homeostasis, modulation of lipid metabolism, induction of autophagy, modulation of oxidative stress and inflammation, and modulation of gut microbiota. However, intermittent fasting may not be suitable for everyone, so it is important that you consult a healthcare professional before starting intermittent fasting. Move more Physical activity is key to reversing fatty liver, even without weight loss. A combination of cardio and strength training can make a significant impact on your health. Aim for three weekly sessions of weightlifting and three cardio workouts, complemented by 8,000–10,000 daily steps. Exercise will enhance insulin sensitivity, which will help the liver process fats more efficiently. A 2018 study found that regular physical activity has a beneficial effect on NAFLD. Various regimens of aerobic and resistance training have been shown to reduce hepatic fat content through improvements in insulin resistance, liver fatty acid metabolism, liver mitochondrial function, and activation of inflammatory cascades. Add protein and fiber (Pic courtesy: iStock) Protein and fiber are essential for liver health. Protein curbs hunger, and thereby prevents overeating, which blocks fat accumulation. The fiber, on the other hand, supports gut health and reduces fat absorption. Try to incorporate foods like eggs, fish, chicken, broccoli, oats, flaxseeds, and chia seeds. Avoid refined carbs Yes, you may be fond of all those chips, breads, and pastries. But if you want to reverse fatty liver, the best bet would be to cut out refined carbs from your diet. Replace them with whole grains such as quinoa and brown rice, starchy vegetables like sweet potatoes, and healthy fats from avocados, olive oil, and nuts. Fans Concerned as Karan Johar Looks Noticeably Thin in Latest Picture Lose weight Overweight and obesity can contribute to fatty liver. Losing just 5–10% of body weight can significantly reduce liver fat. Try to aim for a gradual weight loss through diet and exercise. This way, the weight loss will be sustainable and effective. Several studies have linked even the modest weight reduction to improved liver function.

41st anniversary of The Times of India, Bengaluru: Engineering the future
In the most sought-after engineering college of Karnataka, a four-year computer science seat gets lapped up for a fee of Rs 70 lakh. And if you thought this was too steep a price to pay, consider this: Students from across the country queue at this college as early as December of the previous year. Karnataka, and, more specifically Bengaluru, has been one of the hotspots for engineering education since the 1970s and a pioneer in private technical education in the country. Of the 213 colleges affiliated to Visvesvaraya Technological University (VTU), more than 80 are Bengaluru-based. You Can Also Check: Bengaluru AQI | Weather in Bengaluru | Bank Holidays in Bengaluru | Public Holidays in Bengaluru When Bharat Ratna Sir M Visvesvaraya established the University Visvesvaraya College of Engineering (UVCE) in 1917, it was the fifth engineering college in the country. If that was a humble beginning, then the picture started changing drastically from the late 1950s. That was when the then prime minister Jawaharlal Nehru, in his clarion call for industrialisation, said, 'industrialise or perish'. In the years that followed, at least eight big-ticket public sector industrial units came to Bengaluru, including Hindustan Aeronautics Limited (HAL), Bharat Electronics Limited (BEL), and Hindustan Machine Tools (HMT). by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like An engineer reveals: One simple trick to get internet without a subscription Techno Mag Learn More Undo 'With an ever-growing demand for engineers in the country, engineering colleges started mushrooming,' recalled Seetharamu A S, former faculty at the Institute for Social and Economic Change. 'Basic sciences grew, too. Indian Institute of Science was paving the way for this. Meanwhile, there was a lot of interest in spectroscopy, with Nobel laureate C V Raman's work. All this led to an increased demand for engineering education in the state,' he said. Then came privatisation of professional colleges in Karnataka. In 1946, BMS College of Engineering (BMSCE) became the first private sector initiative in engineering education in India. Soon, several others followed. 'The ecosystem for science and engineering was already set in the city with the PSUs in 1960s. At a time when other states were just beginning to set up private engineering colleges, Karnataka already had 50-60 of those. However, Karnataka did not unscrupulously increase the number of colleges and maintained it at 213, thereby ensuring quality education,' said K N Subramanya, principal of R V College of Engineering. Karnataka was one of the first states to build an umbrella university VTU that brought all technical education under one roof. While many educationists were not in favour of the affiliation system, they agreed that formation of VTU brought in standardisation and quality in technical education. Karnataka was also one of the first states to bring in a Common Entrance Test (CET) in 1994 that ensured meritocracy in admissions, setting benchmarks in engineering education. As a result of these initiatives, in the 1990s, Bengaluru emerged the cradle of IT revolution in the country. The rest, as they say, is history! Bengaluru's story in engineering education is now about keeping up with the times. S Sadagopan, the founder director at International Institute of Information Technology Bangalore, said: 'While institutes like IITs provide quality education, they have not been able to scale up student intake to the extent required. However, many colleges in Bengaluru are now providing quality education with intake as high as 1,000 for some branches. They're able to offer quality education at scale. This is Karnataka's contribution to the nation,' he observed. In addition, there are private universities offering engineering education. Colleges from other states and cities are also venturing into Bengaluru to have a piece of the pie. With artificial intelligence (AI) taking the world by storm, colleges have also undergone makeovers to keep pace. Currently, there are 133 streams available, of which at least 105 are related to computer science and its allied programmes. 'Bengaluru's evolution into India's premier engineering education hub is deeply tied to its thriving tech ecosystem, the early establishment of top-tier institutions, and close industry-academia collaboration,' said Neeti Sharma, CEO, Teamlease Digital. 'Over the past two decades, top engineering colleges in the city have consistently attracted high-quality talent from across India due to robust placement records and proximity to leading tech companies,' she further said. 'With around 12,000 IT/software firms and more than 10,000 startups, Bengaluru offers unmatched industry exposure to engineering students. The city's colleges routinely see the highest number of companies visiting for campus placements,' Sharma added. 'The packages offered are also among the highest in the country. Institutions such as IIIT Bangalore and IISc report average packages of Rs 27-28 LPA, with top offers reaching Rs 65-86 LPA,' Sharma said. According to Sharma, core engineering domains, especially semiconductors, are seeing renewed interest. 'Bengaluru is home to a vast majority of India's chip design workforce, with firms such as AMD, Qualcomm, and Intel expanding their design operations,' she said. It's not just engineering, but colleges in other streams also have mushroomed in the state. According to the All India Survey on Higher Education (AISHE) 2021-22, Bengaluru Urban district has the highest density of colleges in the country, with 1,106 institutions. In comparison, Jaipur has 703, Hyderabad 491, Pune 475 and Prayagraj 398. What Bengaluru has always lacked is an IIT, but there are now colleges in the city that can boast of education on par with the best in the country.

Children exposed to heat wave worldwide may lose up to 1.5 years of schooling: Report
Children exposed early to extreme heat may lose up to 1.5 years of schooling with climate change having a direct impact on education and threatening to undo educational gains of recent decades, according to a new global report. Climate related stressors such as heat, wildfires, storms, floods, droughts, diseases and rising sea levels, affect education outcomes. Most low and middle-income countries are experiencing climate-related school closures every year, increasing chances of learning loss and dropout, it noted.

An analysis linking census and climate data in 29 countries between 1969 and 2012 showed that exposure to higher than average temperatures during the prenatal and early life period is associated with fewer years of schooling, especially in Southeast Asia. "A child experiencing temperatures that are two standard deviations above average is predicted to attain 1.5 fewer years of schooling than children experiencing average temperatures. High temperatures reduced high-stakes test performance in China and led to reductions in both high school graduation and college entrance rates," the report said. Live Events "In the United States, without air conditioning, a school year hotter by 1 degrees Celsius reduced test scores by 1 pc. Very hot school days disproportionately impacted African American and Hispanic students, due to poor infrastructure conditions, accounting for roughly 5 per cent of the racial achievement gap," it added. The report noted that about half of public school districts need to update or replace multiple heating, ventilation and air conditioning systems. "In the most disadvantaged municipalities in Brazil, which were also amongst those most exposed to heat risk, students lost about 1 per cent of learning per year due to rising temperatures," it said. The global report flagged that climate-induced education vulnerability is worse for marginalised populations. Of the 10 countries most affected by extreme weather events in 2019, eight were low- or lower-middle-income countries. Of the 33 countries identified as bearing extremely high climate risks for children, where nearly 1 billion people live, 29 are also considered to be fragile states. In the United States, those with low income or without a secondary school certificate are 15 per cent more likely to live in areas with the highest projected increases in childhood asthma diagnoses due to climate-driven increases in particulate air pollution. "School districts in the United States that received federal disaster recovery funds had higher proportions of students from socially vulnerable groups," the report said. The team flagged that increasingly frequent natural disasters, including floods and cyclones, have led to the deaths of students and teachers and have damaged and destroyed schools. "Following the 2013 floods in Jakarta, access to schools was disrupted, schools were used as emergency shelters and some schools closed because of damage. Among schools surveyed, 81 per cent of those with disaster management plans and a standard operating procedure for dealing with flood emergencies agreed that these were effective in times of crisis," it said.
