Shubhanshu Shukla studies tardigrades' survival in microgravity on space station
In a pathbreaking study aboard the International Space Station (ISS), Group Captain Shubhanshu Shukla, along with his Axiom-4 crewmates, successfully conducted a study on tardigrades, deep sea microscopic extremophiles known for their resilience to extreme study revealed insights into tardigrades' life in microgravity, the Indian Space Research Organisation (Isro) said in a statement on experiment, aimed at understanding tardigrades' survival and reproductive behaviours in space, could have significant implications for developing therapeutic applications on Earth, the statement Shubhanshu Shukla embarked on a biomedical research mission aboard the International Space Station (ISS) with the Axiom-4 mission, becoming the first Indian astronaut in the orbiting centerpiece of Shukla's mission is the Myogenesis Experiment, conducted inside the ISS's Life Sciences Glovebox (LSG).In tandem with the tardigrade study, the Myogenesis investigation is exploring the effects of microgravity on human muscle regeneration. The Gaganyatri team is recording observations and implementing planned interventions, Isro other experiments involve studying microalgae and cyanobacteria under space conditions, which could play a pivotal role in developing regenerative life support systems and ensuring crew nutrition on long-duration space exciting area of research on the ISS focuses on human-machine interaction. The Electronic Displays study is underway, aiming to optimise how astronauts interact with digital systems in involves daily cognitive and interface assessments carried out by 'Shux' (Shukla's call sign), providing insights that could improve operational efficiency in the unique environment of rigorous scientific research, Isro is also prioritising educational outreach onboard the space station. Through its STEM demonstrations conducted onboard the ISS, the Indian space agency aims to inspire students and the public by illustrating scientific principles in a microgravity activities are part of Isro's broader outreach strategy, bringing the wonders of space science closer to Earth, the space body's statement insights derived from these experiments not only expand the understanding of life in space but also have practical applications on Earth. The resilience mechanisms of tardigrades could lead to novel approaches in medical therapeutics, while studies on human physiology and biology could enhance astronaut health and efficiency, Isro said it hoped."The continued research on the ISS underscores the importance of investigating biological and technological challenges in space, paving the way for future missions and innovations in space travel and life sciences," it added.- EndsMust Watch

Indian astronaut works on understanding how human body loses muscle in zero gravity
Group Captain Shubhanshu Shukla embarked on a biomedical research mission aboard the International Space Station (ISS), becoming the first astronaut holding an Indian passport to conduct in-orbit experiments. Operating under the call sign 'Shux', Shukla has begun work on a critical study of muscle degradation in microgravity — an issue that has long challenged space centerpiece of Shukla's mission is the Myogenesis Experiment, conducted inside the ISS's Life Sciences Glovebox (LSG). advertisement 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 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 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 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 role symbolises India's deeper foray into human space research—one that merges space exploration with high-impact health 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
