Indian astronaut works on understanding how human body loses muscle in zero gravity
The research aims to uncover how spaceflight conditions disrupt skeletal muscle development and function. Using 3D skeletal muscle tissue chips, the study simulates the impact of microgravity on muscle cells, revealing troubling changes: muscle fibers become 25.8 per cent thinner and 23.7 per cent shorter, with a 66.3 per cent drop in force generation."These findings could unlock new therapeutic strategies," Isro officials had said earlier. The focus is on key molecular regulators like MyoD1 and MyoG, which play crucial roles in muscle cell growth and repair. Insights from this research could help astronauts maintain muscle strength during long-duration missions and inform treatments for age-related muscle loss and immobility-induced wasting back on Earth.Shukla's mission, part of the privately operated Axiom-4 (Ax-4) spaceflight, includes several other advanced experiments. advertisementA Telemetric Health AI initiative combines ultrasound scans with biometric data to monitor cardiovascular and balance systems in real time. Such systems could revolutionise remote diagnostics and care, particularly in underserved areas on Earth.Another standout project is PhotonGrav, which uses a brain-computer interface headset to track neural activity through cerebral blood flow. The research explores the possibility of thought-controlled spacecraft systems and may someday aid in neurorehabilitation therapies for stroke survivors or individuals with limited mobility.India's participation in Ax-4 is part of a broader international effort, with over 60 experiments from 31 countries. India, through Isro, has contributed seven carefully selected studies to the mission.Shukla's role symbolises India's deeper foray into human space research—one that merges space exploration with high-impact health innovation.As India sets its sights on future lunar and interplanetary missions, Shukla's work aboard the ISS could shape not only how astronauts survive space, but how millions of people thrive on Earth.- EndsTune InMust Watch

Which is better: Rice or Flattened Rice?
Rice and flattened rice (commonly known as poha or beaten rice) are staple grains in Indian households, yet they differ significantly in texture, processing, nutritional profile, and culinary uses. Understanding these differences can help you choose the better option depending on your dietary goals and health needs. Here's a closer look at both. Processing and Texture Rice refers to whole or polished grains of paddy that are typically boiled or steamed before eating. Flattened rice, on the other hand, is made by parboiling rice and then flattening it into thin, dry flakes. While rice grains remain whole and require cooking, poha softens easily with minimal soaking or steaming, making it quicker to prepare. Nutritional Composition Both rice and poha are rich in carbohydrates, but poha has a slightly better nutrient profile due to the parboiling process, which retains some of the nutrients from the husk. Poha contains small amounts of iron, fiber, and B vitamins, especially when made from red rice. White rice, especially the polished variety, is lower in fiber and micronutrients due to the removal of the outer bran layer. Which is more healthier? Flattened rice (poha) and regular rice both offer health benefits, but differ in nutrition and usage. Flattened rice is partially cooked, easy to digest, and lower in calories, making it ideal for light, quick meals and for those with digestive issues. It retains some iron and fiber due to minimal processing and is often enriched in traditional methods. Regular rice, especially brown rice, is richer in fiber, B vitamins, and provides sustained energy, but takes longer to cook and digest. Overall, poha is better for light meals and quick digestion, while rice provides more satiety and sustained energy. Glycemic Index and Digestion Poha generally has a lower glycemic index than white rice, making it a better choice for people with diabetes or those looking to manage blood sugar. It's also light on the stomach and easily digestible, which is why it's often recommended for breakfast or during illness. Rice, especially polished white rice, digests quickly and can cause a quicker spike in blood glucose levels. Cooking and Versatility Poha is quick to cook and doesn't need boiling — just a quick rinse or soak followed by light sautéing. It's versatile in recipes like kanda poha, vegetable poha, or even sweet dishes. Rice, however, requires longer cooking times and is typically used as a base for dal-chawal, biryani, and other heavier meals. The ease of cooking gives poha an edge for busy or health-conscious eaters. Satiety and Weight Management Since poha retains some fiber and expands when soaked, it gives a feeling of fullness without being calorie-dense. This makes it more helpful in weight management compared to polished rice, which is more energy-dense and less filling in small portions. Including vegetables and nuts in poha further improves its satiety value. Which Is Better? Both rice and poha have their place in a balanced diet. If you're looking for a quick, light, and slightly more nutritious option, especially for breakfast or a snack, flattened rice is a better choice. However, for meals requiring a hearty base or if you're seeking higher calorie intake, plain rice works well. Choosing whole grain or red varieties of both rice and poha can further enhance their health benefits.

R Madhavan on Rocketry: The Nambi Effect completing three years of its release: We wanted to change Google's algorithm..
Three years ago, Rocketry: The Nambi Effect blasted its way into Indian cinema, with reviews praising the way the biopic was made. It also garnered attention for the portrayal of aerospace scientist Nambi Narayanan by actor R Madhavan. R Madhavan As the film completed a year of it's release yesterday on July 1, Madhavan was ecstatic and reminisced the making, 'When I started writing the story of Rocketry in 2016 and 17, whenever I Googled Nambi Narayanan, it used to spit out the ISRO spy case or the Maldivian woman affair or something negative about Nambi sir. And while writing the script, I told Vijay, my producer, that, 'you know what, we should make a movie that will change the algorithm on Google to spit out more the right facts about Nambi Sir'. Basically I wanted to change the algorithm about how sir was being perceived by Google- and we have managed to do that. It's been three years since then, can't believe how the time flew.' It was therefore a deeply personal project for Madhavan, who also turned director with Rocketry. He produced the film too. His decision to take creative and narrative ownership has redefined his legacy. It brought the overdue recognition to Nambi Narayanan's immense contributions to India's space program. Released in multiple languages and celebrated globally, the film struck a chord for its sincerity, emotional depth, and purpose. Its impact was acknowledged when Rocketry was honoured with the National Award for Best Feature Film at the 69th National Film Awards. Currently, Madhavan is gearing up for the release of his film Aap Jaia Koi. He also played a pivotal role in the recent Kesari Chapter 2, which fetched him appreciation.

Inside Meta's Superintelligence Lab: The scientists Mark Zuckerberg handpicked; the race to build real AGI
Mark Zuckerberg has rarely been accused of thinking small. After attempting to redefine the internet through the metaverse, he's now set his sights on a more ambitious frontier: superintelligence—the idea that machines can one day match, or even surpass, the general intelligence of humans. To that end, Meta has created an elite unit with a name that sounds like it belongs in a sci-fi script: Meta Superintelligence Lab (MSL). But this isn't fiction. It's a real-world, founder-led moonshot, powered by aggressive hiring, audacious capital, and a cast of technologists who've quietly shaped today's AI landscape. This is not just a story of algorithms and GPUs. It's about power, persuasion, and the elite brains Zuckerberg believes will push Meta into the next epoch of intelligence. The architects: Who's running Meta's AGI Ambitions? Zuckerberg has never been one to let bureaucracy slow him down. So he didn't delegate the hiring for MSL—he did it himself. The three minds now driving this initiative are not traditional corporate executives. They are product-obsessed builders, technologists who operate with startup urgency and almost missionary belief in Artificial general intelligence (AGI). Name Role at MSL Past Lives Education Alexandr Wang Chief AI Officer, Head of MSL Founder, Scale AI MIT dropout (Computer Science) Nat Friedman Co-lead, Product & Applied AI CEO, GitHub; Microsoft executive B.S. Computer Science & Math, MIT Daniel Gross (Joining soon, role TBD) Co-founder, Safe Superintelligence; ex-Apple, YC No degree; accepted into Y Combinator at 18 Wang, once dubbed the world's youngest self-made billionaire, is a data infrastructure prodigy who understands what it takes to feed modern AI. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like My baby is in so much pain, please help us? Donate For Health Donate Now Undo Friedman, a revered figure in the open-source community, knows how to productise deep tech. And Gross, who reportedly shares Zuckerberg's intensity, brings a perspective grounded in AI alignment and risk. Together, they form a high-agency, no-nonsense leadership core—Zuckerberg's version of a Manhattan Project trio. The Scientists: 11 defections that shook the AI world If leadership provides the vision, the next 11 are the ones expected to engineer it. In a hiring spree that rattled OpenAI, DeepMind, and Anthropic, Meta recruited some of the world's most sought-after researchers—those who helped build GPT-4, Gemini, and several of the most important multimodal models of the decade. Name Recruited From Expertise Education Jack Rae DeepMind LLMs, long-term memory in AI CMU, UCL Pei Sun DeepMind Structured reasoning (Gemini project) Tsinghua, CMU Trapit Bansal OpenAI Chain-of-thought prompting, model alignment IIT Kanpur, UMass Amherst Shengjia Zhao OpenAI Alignment, co-creator of ChatGPT, GPT-4 Tsinghua, Stanford Ji Lin OpenAI Model optimization, GPT-4 scaling Tsinghua, MIT Shuchao Bi OpenAI Speech-text integration Zhejiang, UC Berkeley Jiahui Yu OpenAI/Google Gemini vision, GPT-4 multimodal USTC, UIUC Hongyu Ren OpenAI Robustness and safety in LLMs Peking Univ., Stanford Huiwen Chang Google Muse, MaskIT – next-gen image generation Tsinghua, Princeton Johan Schalkwyk Sesame AI/Google Voice AI, led Google's voice search efforts Univ. of Pretoria Joel Pobar Anthropic/Meta Infrastructure, PyTorch optimization QUT (Australia) This roster isn't just impressive on paper—it's a coup. Several were responsible for core components of GPT-4's reasoning, efficiency, and voice capabilities. Others led image generation innovations like Muse or built memory modules crucial for scaling up AI's attention spans. Meta's hires reflect a global brain gain: most completed their undergrad education in China or India, and pursued PhDs in the US or UK. It's a clear signal to students—brilliance isn't constrained by geography. What Meta offered: Money, mission, and total autonomy Convincing this calibre of talent to switch sides wasn't easy. Meta offered more than mission—it offered unprecedented compensation. • Some were offered up to $300 million over four years. • Sign-on bonuses of $50–100 million were on the table for top OpenAI researchers. • The first year's payout alone reportedly crossed $100 million for certain hires. This level of compensation places them above most Fortune 500 CEOs—not for running a company, but for building the future. It's also part of a broader message: Zuckerberg is willing to spend aggressively to win this race. OpenAI's Sam Altman called it "distasteful." Others at Anthropic and DeepMind described the talent raid as 'alarming.' Meta, meanwhile, has made no apologies. In the words of one insider: 'This is the team that gets to skip the red tape. They sit near Mark. They move faster than anyone else at Meta.' The AGI problem: Bigger than just scaling up But even with all the talent and capital in the world, AGI remains the toughest problem in computer science. The goal isn't to make better chatbots or faster image generators. It's to build machines that can reason, plan, and learn like humans. Why is that so hard? • Generalisation: Today's models excel at pattern recognition, not abstract reasoning. They still lack true understanding. • Lack of theory: There is no grand unified theory of intelligence. Researchers are working without a blueprint. • Massive compute: AGI may require an order of magnitude more compute than even GPT-4 or Gemini. • Safety and alignment: Powerful models can behave in unexpected, even dangerous ways. Getting them to want what humans want remains an unsolved puzzle. To solve these, Meta isn't just scaling up—it's betting on new architectures, new training methods, and new safety frameworks. It's also why several of its new hires have deep expertise in AI alignment and multimodal reasoning. What this means for students aiming their future in AI This story isn't just about Meta. It's about the direction AI is heading—and what it takes to get to the frontier. If you're a student in India wondering how to break into this world, take notes: • Strong math and computer science foundations matter. Most researchers began with robust undergrad training before diving into AI. • Multimodality, alignment, and efficiency are key emerging areas. Learn to work across language, vision, and reasoning. • Internships, open-source contributions, and research papers still open doors faster than flashy resumes. • And above all, remember: AI is as much about values as it is about logic. The future won't just be built by engineers—it'll be shaped by ethicists, philosophers, and policy thinkers too. Is your child ready for the careers of tomorrow?
