Onboard Shubhanshu Shukla's mission: Study to enable diabetes patients travel to space
As of now, insulin-dependent diabetic patients are not selected to become astronauts. That is because the space environment, particularly micro-gravity conditions, makes it difficult to control and maintain blood sugar levels. But scientists around the world have been working for the last several years to make this possible.
A diabetes-related research project on Axiom-4 mission marks an important step in that effort.
One or more astronauts on the mission — it is not disclosed who they may be — will wear Continuous Glucose Meters (CGMs) throughout their stay in space, and their real-time blood sugar measurements will be monitored by the research team on Earth.
They will also collect blood samples during their flight which can be tested later to validate the readings of the CGM.
The mission will also carry two varieties of insulin pens: one refrigerated, the other in ambient air conditions. These will check whether their integrity remains intact in micro-gravity conditions.
'One of the primary objectives of the study is collect data that is relevant for enabling space travel possible for diabetic people. But it is not just that. The research can be helpful for the management of diabetes on Earth as well,' Mohammad Fityan, the Dubai-based clinical lead for this research project called Suite Ride, told The Indian Express in an interview.
Fityan is the chief medical officer at the Burjeel Medical City, a hospital in Dubai which is collaborating with Axiom Space for this research project.
Diabetes research in space is not new. Studies on this has been going on for several years. Even CGMs have been worn by astronauts before. The astronauts on the Polaris Dawn mission, a private mission that remained in space for five days in September last year, wore CGMs. But this was limited to collecting blood sugar data while in space.
Last year, the Galactic 07 mission, a sub-orbital flight operated by Virgin Galactic, demonstrated for the first time that commercially available insulin pens can be used to effectively deliver the hormone in space.
Fityan said the study on Axiom-4 mission is a more 'well-rounded attempt' on diabetes research in space.
'Real-time measurement of blood sugar, the validation of CGMs, and an assessment whether insulin maintains its viability and integrity in space… these are the things that have never been done before,' Fityan said.
'The study will continue for the two weeks of the mission. This is still a short-term study. We would not be able to monitor the blood glucose levels over a longer period. But even this data is very critical for understanding the effect of zero-gravity on diabetes. Microgravity removes many of the physical and gravitational forces acting on the body, allowing us to observe metabolic processes in a fundamentally different context,' he said.
Fityan said the research was relevant for diabetic people on Earth as well. 'Previous studies on the International Space Station for example have shown that the effect of microgravity causes fluid shifts in the astronauts. This kind of situation is similar to long-term bed-ridden patients, whose movement is severely restricted. The data that we are hoping to get from the Axiom-4 mission might be very helpful in improving the management of diabetes on Earth as well,' he said.
'Then there is this possibility of the data throwing up some unexpected insights which can lead to secondary outcomes. This kind of thing happens all the time in scientific research,' he said.

Kerala: High alert in 3 districts after suspected Nipah virus cases
The Kerala government on Friday issued a high alert in three districts after two suspected cases of the Nipah virus were detected in the state, The Hindu reported. One of the cases was later confirmed. The alerts were issued for Malappuram, Palakkad and Kozhikode districts. The two cases included an 18-year-old woman from Malappuram, who died on Tuesday in Kozhikode from acute encephalitis syndrome, and a 38-year-old woman from Palakkad currently being treated in Malappuram, the newspaper reported. The two women had shown symptoms consistent with the virus during routine testing. Subsequently, preliminary tests conducted at the government medical colleges in Kozhikode and Malappuram indicated the possibility of the virus, Manorama News reported. The samples were sent to the National Institute of Virology in Pune in accordance with the standard protocol for confirmation. On Friday, the institute confirmed the infection in the 38-year-old woman, while the test result of the 18-year-old was awaited, The Hindu reported. After the cases came to light, state Health Minister Veena George convened an emergency meeting and confirmed that preventive actions had been intensified in the state in line with the Nipah virus protocol, Hindustan Times reported. George added that police assistance had been sought to help trace persons who may have been in contact with the suspected cases. State and district-level helplines were being set up to provide assistance, she said. Twenty-six rapid response teams had been deployed to carry out contact tracing, monitor symptoms and spread public awareness. Officials were also directed to investigate unnatural or unexplained deaths reported in the past few weeks, the minister said, adding that this was 'one of the key warning signs of a potential outbreak'. The Nipah virus is a ' zoonotic illness ' transferred from animals such as pigs and fruit bats to humans. The virus can also be caught through human-to-human transmission. It causes fever and cold-like symptoms in patients. The infection can also cause encephalitis, which is the inflammation of the brain, and myocarditis, or the inflammation of the heart, in some cases. In May, a 42-year-old woman in Malappuram had tested positive for Nipah, The Indian Express reported. The woman, who was admitted with symptoms of encephalitis, recovered from the infection. Since 2018, Kerala has experienced five Nipah outbreaks. According to The Indian Express, only seven patients who tested positive have survived till date: one in Kozhikode in 2018, another in Kochi in 2019, four in Kozhikode in 2023 and the 42-year-old woman in May. In 2018, 17 out of 18 infected persons had succumbed to the disease, while one death was reported in 2021. In 2023, two deaths due to the Nipah virus were recorded. Last year, the state reported two deaths.

From eating to sleeping in space: Shubhanshu Shukla answers students from ISS
Space intrigues all, especially children. So when the students of different schools here got the opportunity to talk to astronaut Shubhanshu Shukla, who is onboard the International Space Station (ISS), they relished it. Shubhanshu Shukla also described the launch experience of the Axiom Mission 4 from the Kennedy Space Centre in Florida on June 25. (ANI) What do astronauts eat? How does one sleep in space? What happens if someone falls sick there? How does the body adjust to space, and how much would it take to readjust on Earth? From his orbital post on the ISS, Shukla enthusiastically gave detailed answers to these questions posed by the students who had assembled at the City Montessori School here. The students also sought to know about the benefits of the space programme and what part of the space visit is most enjoyable. During the interaction, Shukla, the first Indian to reach the ISS, described the launch experience of the Axiom Mission 4 from the Kennedy Space Centre in Florida on June 25 as "amazing" and "dynamic". About the question on sleeping arrangements while in space, he said, "It is fun actually because in space there is no floor and no ceiling. So if you were to come and visit the station (ISS), you would find someone sleeping on the walls, someone on the ceiling." "It is so easy to float up and tie yourself to the ceiling. The challenge is to be found at the same place where you slept at night and to ensure that we tie our sleeping bags to ensure we don't float away to some other place," Shukla said. A student said that when asked what happens if someone falls ill in space, the astronaut replied that they carry they carry adequate medicines in case things go wrong. During the interaction, Group Captain Angad Pratap, who is part of India's maiden manned space mission Gaganyaan, was in Lucknow to create awareness among the youth about space programmes. The student interaction was part of ISRO's Vidyarthi Samvad Programme. Shukla, who is the first Indian to reach the ISS, is also one of the four astronaut-designates for Gaganyaan. A student said that Shukla told them that astronauts hardly get any free time. "But they do watch things or play some sports," he said. "However, one thing that astronauts look forward to is to go out and gaze into space and take a good view of the Earth -- it is very beautiful," a student, who was part of the interaction, told PTI. Talking about the challenges of getting the body readjusted back on Earth, Shukla told his audience that the biggest challenge is the absence of gravity. "Space is a new situation for the body. So like today, I am feeling much better from what I was feeling on day one here," the astronaut said. "My body has now kind of adapted to microgravity, but when I return to Earth, my body would have to readapt to gravity. This is a challenge again, and this adaptation will be required on re-entering Earth. A lot of preparations and procedures are required because space is a very dynamic place," he added. Asked what astronauts eat, Shukla said that most of the food is pre-packaged, and adequate care is taken to ensure that they have enough nutrition. Food becomes one of the main sources of motivation or pleasure in space, he said. "Different food items are laid down and astronauts get to taste all of those and whatever they prefer is packed," said Shukla, who during his interaction with Prime Minister Narendra Modi had told him that he had carried desserts like Gazar Ka Halwa, Moong Dal Ka Halwa and Aam Ras with him to space. A student wanted to know his take on the effect that space has on mental health. At this, Shukla, while admitting challenges, added that modern technology has ensured that astronauts get to connect with family and friends. "It helps a lot," he said. Another student said, "He told us that he finds such interactions immensely rewarding because this shows us the future we have and the possibilities that exist, so that we can see what lies ahead of us, and this is what we have to aim at." Wing Commander Pratap told the students in Lucknow to stay motivated for the next couple of decades, which will witness immense possibilities unfolding for human spaceflight in India. He spoke of the exciting and challenging career in aerospace sciences. "It was all so exciting. Group Captain Shubhanshu explained the varied nuances, challenges, and excitement of space travel, while Wing Commander Pratap motivated us to devote ourselves to science," a student said. "Among other things, we could either become researchers or join the armed forces as an experimental test pilot for an exciting and challenging career." Among other things, Wing Commander Pratap highlighted the traits of Shukla, with positivity being the key one. Another student said that when asked about how one stays fit in space where microgravity comes in play, Shukla said, "On Earth, we always have loading on our body due to gravity and the muscles are always utilised while walking, sitting, or even standing." "But that is not the case in microgravity, as one suffers muscle loss. It is very important for astronauts to keep exercising," Shukla told the students and spoke of his exercise routine. "There is a bicycle that we exercise on. Interestingly, there is no seat on the cycle because in microgravity, you are floating. So you just lock on to the pedals, tie yourself to the belt and then you start exercising. "There is also an exercise machine in which you can do all forms of exercises," he told the students while also demonstrating how one moves in space.

Ramayana's Namit Malhotra opens up about working on Oscar-winning VFX for Christopher Nolan's Interstellar; read
The excitement in the air for Nitesh Tiwari's epic Ramayana is palpable. With an ensemble cast that includes some of the biggest names in B-Town — Ranbir Kapoor, Ravi Dubey, Yash, Sai Pallavi, and Sunny Deol — all eyes are also on Namit Malhotra, the brain behind the film's VFX. The 49-year-old has helmed the VFX design and production on not only Ramayana but his name is also attached to Hollywood cult classics like Dune (2021), Interstellar (2014), Avatar (2009) and more. Namit Malhotra and Yash Education and career trajectory You've probably read about him already. Born into a film family, Namit is the son of producer Naresh Malhotra and the grandson of cinematographer MN Malhotra. After completing his education in computer graphics, he launched his first company, Video Workshop. In 1997, he merged it with his father's film production and rental business to form Prime Focus. Then, in 2014, Prime Focus merged with the UK-based VFX giant Double Negative (DNEG). Since then, the company has provided visual effects for landmark films like Blade Runner 2049 (2017) and Tenet (2020). Over the last ten years, DNEG has won the Best Visual Effects Oscar seven times — eight times in total. A throwback to Interstellar One of the films that won the Best Visual Effects Oscar at the 2015 Academy Awards was Interstellar. In an older interview with James Whittaker, Namit Malhotra opened up about what it was like to work on the film with none other than Christopher Nolan. 'My favourite filmmaker in the world is Christopher Nolan,' he said. 'He's the most stellar, one-of-a-kind director that I've ever seen. I compliment him all the time because I feel like he's one filmmaker who is so precise in his vision, in his execution.' Speaking about the work they did on Interstellar, he said, 'We make a film for Mr. Nolan like Interstellar. You're talking about creating something that the world of science doesn't have — how does light travel through the black hole or the wormhole, and what does that look like?' 'The whole aspect of creating those vistas and visions about being in space and being in that part of the world that you've never really seen before... and making sure that whatever we do is hiding behind the emotional graph of the connect the father has with his daughter, and how he's really trying so hard to make that connection with her as he's battling through all those challenges and complexities of time and space,' he added. 'What becomes critical is that you can make something look really pretty and you can make something look really nice, but how do you make it authentic? That is where there's no one like Mr. Nolan to really drive the sense of realism and authenticity. So for us, we're making those scenes — when they're in the spaceship and they see the world outside, and he's falling through and he sees his daughter behind the bookshelf — those are all the scenes that come to my mind that needed an incredible amount of detail. While it has splendour, it doesn't take you away from the emotion of the scene.' He summed it up perfectly: 'That's what I always say to people — visual effects is not the reason why a film is going to be connecting with people. In fact, the more seamless we make it, the more successful the film will be. Further reflecting on his time working on Avatar, Namit highlighted how important it is for the world to feel real. 'It's not just a pretty visual, it's your environment, it's what you now believe. You're seeing the characters and you believe that's happening to them. You feel for them — you have joy, you have tears.' Now, onto Ramayana 'This is personally my dream being fulfilled — of becoming a creative collaborator in that journey,' he said about working on Ramayana. Speaking to the media in Mumbai during the teaser premiere, Namit described Ramayana as a project much bigger than a film. 'This is a cultural movement for every Indian around the world. With Ramayana, we're not just retelling history; we're introducing our legacy to the world. Bringing together the finest global talent allows us to tell this story with authenticity, emotion, and state-of-the-art cinematic innovation. We've seen Ramayana portrayed before — but this version reimagines its landscapes, creatures, and battles with the scale and splendour they deserve. As Indians, this is our truth. Now, it will be our gift to the world.' About the film Rooted in a mythological age ruled by the divine trio — Brahma, Vishnu, and Shiva — the story traces the rise of Ravana (Yash) who grows powerful enough to disrupt the order of the cosmos. To restore balance, Vishnu takes human form as Rama (Ranbir Kapoor), leading to a legendary battle between good and evil. Ramayana will be released worldwide — Part 1 on Diwali 2026 and Part 2 on Diwali 2027.
