A team of scientists, headed by Central University of South Bihar's environmental science department head Pradhan Parth Sarthi, has found that as per the current status of urbanisation, Patna — which is also being developed as a smart city — is facing several climatic challenges, including urban heat islands and flooding, caused by extreme weather conditions. The study indicates that in future, during the period of 2030-65, under the existing global warming scenario, the city may get a significant increasing trend in number of days with temperatures greater than 40°C and also a considerable increase in the percentage of days with the daily maximum temperature above normal.
Similarly, there could be a deceasing trend in the number of days with a minimum temperature less than 10°C.
Such possible changes in extreme temperature indices may have a significant impact on urban climate. Furthermore, it could also impact public health by increasing the incidence of heat-related illnesses such as heat stress or exhaustion, according to the study.
The study observes that urbanisation in the past few decades has been very fast as people in large numbers have migrated from villages or small towns to Patna for a better quality of life and better economic opportunities.
The Gangetic plains are home to 40% population of India. Patna is the best example of fast urbanisation, where most of the high-rises are without green spaces and green rooftops, in complete violation of the environmental norms.
To overcome these issues, the study said, the Smart Cities Mission was launched by the Prime Minister on June 25, 2015. The main objective of the mission was to promote cities that provide core infrastructure, and clean and sustainable environment, besides giving a decent quality of life to their citizens through the application of "smart solutions".
The co-investigator of the study team, Prabhat Kumar, pointed out that the results of the study may be utilised for developing Patna as a smart city. They have done similar analysis for Delhi, Lucknow, Prayagraj and Varanasi, he added.

Shubhanshu Shukla's Space Insurance Could Be The Costliest In The World. Here's What It Covers
Last Updated: Astronaut Shubhanshu Shukla, who represents India in a multilateral crew aboard the ISS, has secured insurance coverage that may be worth upwards of Rs 200 crore For the next 14 days, astronaut Shubhanshu Shukla will orbit above Earth aboard the International Space Station (ISS) as part of NASA's Axiom Mission 4. But behind this milestone lies one of the most high-stakes financial undertakings known to mankind – space insurance, the most expensive insurance in the world. Shukla, who represents India in a multilateral crew aboard the ISS, has secured insurance coverage that may be worth upwards of Rs 200 crore. This is part of the approximately $60 million (about Rs 500 crore) package paid by the Centre to Axiom Space in 2025, which includes mission costs, astronaut training, transportation via SpaceX's launch vehicle, and accident insurance. Spaceflight is considered one of the riskiest ventures humans can undertake. Insurance coverage for astronauts reflects that danger, with policies ranging between Rs 40 crore and Rs 160 crore per individual, and in cases involving long-duration missions or high-cost payloads, the coverage can go even higher. Insurance for astronauts isn't just about covering the spaceflight itself. It typically begins weeks or months in advance, encompassing the high-risk training period and continues until the astronaut returns safely to Earth. The premium alone for such insurance can range from 10 to 20 percent of the total insured amount, a massive figure compared to standard life or travel insurance. The price tag is justified by the stakes. A minor technical glitch in space can be fatal. Unlike on Earth, there is no scope for emergency rescue. Every phase, from launch to docking to their stay aboard the ISS, and their re-entry, carries serious risk. Death or serious injury during launch, orbit, or return. Losses due to mission cancellation, training interruption, or mission delay. Damage to mission-critical equipment and spacecraft. Training injuries, provided they occur during officially sanctioned programs. Insurance may not cover accidents stemming from willful negligence, intoxication, concealed medical issues, or acts of war and terrorism. Who Insures Astronauts? Space missions are often insured by major national space agencies or through partnerships with global private insurers. In the United States, NASA provides life and accidental death insurance to its astronauts and their families. For international missions like the ISS, participating nations ensure that their astronauts are insured, either through their space agencies or government-backed policies. Private missions, like Axiom's, rely on commercial insurance providers. Some of the key players in the global space insurance market include: These companies specialise in high-risk sectors, including aviation, satellite deployment, and manned space travel. History Of Space Insurance And Compensation The concept of insuring space missions is not new; but it has evolved significantly since the early Apollo days. Back in the 1960s, NASA was unable to offer formal insurance, so Apollo astronauts would leave behind signed autographs, which their families could later sell if tragedy struck. The need for structured insurance became painfully evident after a string of catastrophic accidents: Apollo 1 (1967): A fire during a ground test killed three astronauts. NASA compensated families through a special fund. Challenger Disaster (1986): The shuttle exploded 73 seconds after liftoff, killing all seven astronauts. Government and private compensation was awarded. Lloyd's of London reportedly settled claims worth $7 million per astronaut. Columbia Disaster (2003): The shuttle disintegrated during re-entry, killing all seven crew members, including Kalpana Chawla. Compensation came through NASA's Federal Employees Group Life Insurance (FEGLI), special agency funds, and a dedicated Columbia Families Trust set up by the US Congress. Soviet Missions (Soyuz 1 in 1967, Soyuz 11 in 1971): Fatal accidents were followed by state-provided compensation, though specifics remain classified. What Happens In Case Of Accident? In the unfortunate event of a spaceflight casualty, claims can be made by the astronaut's family or the mission-operating agency. Settlements often depend on the terms of the insurance and the nature of the accident. With public interest and national pride often involved, governments tend to step in with supplemental compensation as well. top videos View all Shukla's Mission And India's Investment India's decision to send Shubhanshu Shukla on the Axiom-4 mission marked a significant stride in its growing involvement in human spaceflight. The seat purchased from Axiom reportedly cost $60 million, a figure that includes not only the flight but the weeks-long astronaut training, space station stay, and comprehensive insurance coverage.

Are you a tea-aholic? New study says two cups a day may protect your heart, but there is a catch
If you're among the millions of Indians who begin and end their day with a cup of tea, there might be more than comfort brewing in your teacup. According to a report from the Daily Mail, A new study suggests that drinking up to two cups of unsweetened tea daily could significantly reduce the risk of heart failure and stroke. However, the benefits disappear the moment you add sugar or sweeteners—a caveat that may disappoint many desi chai lovers who prefer their tea sweet, milky, and spiced. Sweet Sip, Bitter Risk? The research, published in the International Journal of Cardiology: Cardiovascular Risk and Prevention, draws from a study conducted by Nantong University in China, which analyzed data from 177,810 UK adults with an average age of 55. While the study is based on British tea habits, the findings carry important implications for India, where tea culture is deeply embedded across all regions and age groups. Over a period of nearly 13 years, researchers tracked the health outcomes of these participants, among whom 147,903 were tea drinkers. Crucially, 68.2% of them consumed their tea without any sugar or artificial sweeteners. The results were striking. Those who drank up to two cups of unsweetened tea per day showed a 21% lower risk of heart failure, a 14% reduced risk of stroke, and a 7% lower chance of developing coronary heart disease. But here's the catch: none of these cardiovascular benefits were observed in individuals who added sugar or sweeteners to their tea. iStock Those who drank up to two cups of unsweetened tea per day showed a 21% lower risk of heart failure. (Image: iStock) The Science Behind the Sip What makes unsweetened tea so heart-friendly? The answer lies in the tea's polyphenols—naturally occurring compounds that have powerful antioxidant and anti-inflammatory properties. These compounds help protect the heart and blood vessels by reducing oxidative stress and inflammation, two major culprits behind cardiovascular diseases.

Both are known to promote insulin resistance and metabolic dysfunction, conditions that raise the risk of heart disease. In essence, sugar doesn't just add calories—it may also cancel out tea's natural health benefits. Time for a Desi Detox? In India, tea is not just a beverage—it's a ritual. But our preferred version of chai often involves generous amounts of sugar, milk, and sometimes even condensed milk or cream. While this makes for a delicious pick-me-up, it may not be the healthiest habit, especially for those concerned about heart health. Given the study's findings, now might be a good time for Indian tea aficionados to rethink their brew. Swapping sugary chai for lighter, unsweetened variants like green tea, black tea, or herbal infusions could be a small change with big cardiovascular payoffs. The research reinforces a growing body of evidence that everyday dietary choices can have long-term health consequences. While tea itself continues to hold its place as a beneficial beverage, how we consume it matters immensely.

Urban growth may fuel heat stress in Patna, say scientists
1 2 Patna: The historic city of Patna, which has experienced rapid urbanisation over the past few decades, is likely to face more extreme heat and fewer cold days in the coming years, according to a new study published in the 'International Journal of Theoretical and Applied Climatology'. The research, led by Pradhan Parth Sarthi, head of the environmental science department at the Central University of South Bihar, highlighted the increasing climatic challenges facing Patna, a city also undergoing development as part of the Smart Cities Mission. These challenges include the formation of urban heat islands and more frequent flooding, both linked to extreme weather events. The study projected that between 2030 and 2065, under the current global warming scenario, Patna will experience a significant rise in the number of days with temperatures exceeding 40°C. It also forecast a considerable increase in the percentage of days when the daily maximum temperature will be above normal. Conversely, the number of colder days – with minimum temperatures below 10°C – is expected to decline. "Such changes in extreme temperature indices may have a major impact on the urban climate," the study said. It warned of potential consequences for public health, including an increase in heat-related illnesses such as heat stress and exhaustion. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Kardioloog: Buikvet na je 50e?
