Big tension for China, Pakistan as Indian satellites are practicing
Big tension for China, Pakistan as Indian satellites are practicing "dogfight" in space for…, aim is to…
Satellite Dogfighting in Space: From carrying rockets on a bicycle to landing a spacecraft on the moon's south pole, the journey of Indian Space Research Organisation (ISRO) and India's space sector is nothing less than a fairy tale. Now, India's dominance in space is continuously increasing as the country has emerged as the cheapest option to launch other countries' satellites in space. From Chandrayaan-3 to Aditya L-1, India has proved its prowess in the space sector to the world. In the recent development, India is conducting a rare and very sophisticated 'dogfight' in space between 'chaser' and 'target' satellites, orbiting about 500 km above Earth. ISRO is going to conduct the operation after Chinese defense satellites practised 'dogfight' in the low Earth orbit last year. Notably, a dogfight in space refers to the strategic, close-quarters maneuvering of spacecraft, similar to aerial dogfights between fighter jets. Improved Expansion Of Spadex Missions
The unique effort by India is another extension of ISRO's SpadeX mission. ISRO Chairman Dr V Narayanan told NDTV that SpadeX mission in India has successfully shown the 'docking and undocking process twice'. He informed that after the extended docking and undocking manoeuvres, both the satellites still had 50 percent fuel left. What Is The View Of Space Like?
According to reports, the two Indian satellites – flying in space at a speed of 28,800 kmph participated autonomously in this precise flight pattern. Both satellites conducted rendezvous and proximity operations. A recent near-encounter between two satellites happened after days of manual movements to adjust their orbits. China Also Conducted 'Dogfight'
The Dragon also demonstrated its capabilities by several satellites. Even the United States mentioned that its rivals are closing the technology gap. SPADEX Satellites Continue To Make An Impact
India's ISRO successfully conducted a second docking manoeuvre of its SPADEX satellites (SDX 01 and SDX 02) on April 20, followed by a successful power transfer test between the two satellites on April 21st. Heat Transferred From One Satellite To Another
Notably, the experiment also involved operating a heater element in one satellite through power from the other satellite. The duration of power transfer was about 4 minutes, and the performance of the satellites was as expected. In the second docking attempt, docking was accomplished with full autonomy from an inter-satellite distance of 15 meters. In the first docking attempt, an additional hold point was manually used at an inter-satellite distance of 3 meters.
The first docking was achieved on January 16 this year. ISRO successfully docked two Indian satellites orbiting in space at 475 km above the Earth, making it the fourth country to learn docking after Russia, the US and China.
India launched the SpadeX mission using its reliable and low-cost PSLV rocket on December 30 last year. Docking is an enabling technology for upcoming missions such as Chandrayaan-4 and the Indian Space Station.

Germany's Max Planck society emerges as magnet for US researchers amid Trump-era turmoil
Germany's Max Planck Society has recorded a dramatic threefold increase in applications from the United States, reflecting growing unease among American scientists over the future of research under President Donald Trump's administration. The spring 2025 recruitment round saw 81 applications from early-career women scientists in the US, compared to just 25 in the previous year as reported by Reuters. 'Applications from other parts of the world have remained constant. The surge is distinctly American,' confirmed Max Planck president Patrick Cramer. Top US institutions at the center of the exodus Almost half of the new US applicants are affiliated with just five institutions—Harvard University, Stanford University, the Massachusetts Institute of Technology (MIT), the National Institutes of Health (NIH), and the University of California. The Max Planck Society, a German state-funded research network with 84 institutes, a €2 billion annual budget, and 39 Nobel laureates, is now considering hiring 20 candidates, up from the originally planned 12, if the quality threshold is met. Research crackdown and the Harvard controversy The migration of talent follows the Trump administration's revocation of Harvard University's certification to host international students, a move currently blocked by a federal court. The policy mandates that foreign students either transfer to compliant institutions or lose their legal status in the US. The White House has indicated intentions to broaden the restrictions to additional universities. These developments have sent shockwaves through the global academic community, especially as prominent scholars, such as Yale historian Timothy Snyder, have already resigned in protest and relocated to institutions abroad. Europe seeks to absorb displaced talent Cramer, recently returned from discussions in the US, revealed to Reuters that international research leaders are increasingly focused on safeguarding academic talent. 'Our main concern is that a whole generation of scientists may be lost to global science,' he said. 'Europe must become a safe haven and help bridge the years ahead.' The German government is preparing a national initiative, tentatively titled the '1,000 Brains' programme, to expand research infrastructure in anticipation of an influx of international academics fleeing US policy disruptions. Germany's call to action: A wounded scientific benchmark Petra Olschowski, the research minister of Baden-Württemberg—home to four of Germany's 11 top-tier universities—warned that the global research ecosystem could suffer if American institutions continue to lose credibility. He said in an interaction with Reuters, 'Harvard and other major US universities are our benchmarks,' she said. 'That very standard is now under threat.' Global science at a crossroads Despite European enthusiasm to accommodate affected scholars, budgetary constraints remain a concern. Still, research organisations across the continent are aligning their efforts to counterbalance the instability in the US. As Trump's education policies grow increasingly nationalistic, Europe is positioning itself not just as an academic alternative, but as a sanctuary for scientific inquiry in peril.

THIS fibre mimics ozempic and can help in dramatic weight loss
We've heard about Ozempic, the diabetes drug making waves for its dramatic weight loss effects. But what if something as simple as a fiber found in oats and barley could offer similar benefits—naturally? That's the idea behind new research from the University of Arizona and the University of Vienna, which suggests a particular kind of fiber—beta-glucan—might help with weight loss and blood sugar control in ways that mimic Ozempic, without the medication. For years, fiber has taken a backseat in nutrition discussions, overshadowed by protein and carbs. But in recent times, it's making a serious comeback, especially as scientists continue to discover how important it is for our gut health. Our digestive system is home to trillions of bacteria, often referred to as the gut microbiome. These microbes feed primarily on fiber, and in return, they help regulate everything from digestion to immune function. Now, researchers are starting to uncover how specific types of fiber might also play a role in managing weight. In the 2024 study, researchers fed various fiber supplements to mice on a high-fat diet. These included common fiber types like wheat dextrin, pectin, resistant starch, and cellulose. Surprisingly, only one fiber stood out—beta-glucan. Mice that consumed beta-glucan lost weight and body fat within just a few weeks, while the others didn't see those benefits, even though their gut bacteria changed. That's an important distinction: it's not just about feeding your gut—it's about feeding it the right kind of fiber. What makes 'Beta-Glucan' special? Beta-glucan is a soluble fiber, meaning it dissolves in water and can be easily fermented by gut bacteria. It's naturally found in whole grains like oats and barley—foods you probably already have in your pantry. In the study, mice that ate beta-glucan developed higher levels of a beneficial gut bacterium called Ileibacterium , which other studies have already linked to weight loss. These mice didn't even reduce their food intake, but they still lost weight—because their metabolism changed. One key change? The production of a gut chemical called butyrate, which is made when bacteria digest fiber. Butyrate helps trigger the release of GLP-1, the same appetite-suppressing hormone that Ozempic is designed to mimic. So in essence, eating more beta-glucan may help your body naturally produce GLP-1, helping regulate your appetite and blood sugar without the need for medication. More than just weight loss But the benefits don't stop there. Butyrate may also improve gut lining health, support liver function, and reduce inflammation. Scientists believe there's still more to uncover about how these compounds work together to support weight management and overall wellness. However, it's important to note: this research was done in mice. While the results are promising, human trials are still needed to confirm whether beta-glucan works the same way in people. Sources of Beta-Glucan Beta-glucan slows the passage of food in the intestine. This increases the time taken by the body to digest food, which in turn keeps you full for a longer time. And they are also easily available naturally. Here are a few foods that you can include in your daily diet oats barley sorghum rye maize triticale wheat durum wheat rice mushrooms seaweed One step to a healthier you—join Times Health+ Yoga and feel the change
