Axiom 4 and Shubhanshu Shukla lift off: How diabetes and cancer research on board ISS will impact treatment
The first is related to people with insulin-dependent diabetes and whether they can travel to space. As of now, they 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.
Diabetes research
One of the astronauts will be wearing 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 microgravity conditions.
'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, said. 'Previous studies on the International Space Station (ISS) 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 or are in intensive care. 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 added.
These include studies on muscle health, microbial life, and how astronauts interact with technology in microgravity. A key focus will be on diabetes-related research, specifically examining insulin and glucose behavior in space using continuous glucose monitors (CGMs).
Even after the astronauts return, the impact of their journey will continue. Data from CGMs, blood samples, and insulin tests will be analysed in ground-based labs.
Muscle health
Research will investigate muscle degeneration and identify countermeasures. It will also investigate the effects of space flights on joints and blood flow.
Algae as food
Studies on cyanobacteria and microalgae will explore their viability for use in life support systems and as a potential food source. Resilient organisms like tardigrades, will be studied for their survival and gene activity in space.
Cancer Research
Previous research has shown cancer stem cells can regenerate more easily and become more resistant to therapies in microgravity. The study will also look at how microgravity affects stem cell aging. Researchers will use tumour organoids, specifically from triple-negative breast cancer, to validate previous findings on early cancer warning signs and to test potential new drug targets. These studies will be conducted with the help of the Sanford Stem Cell Institute and the JM Foundation. Microgravity allows scientists to identify better drug candidates for faster-progressing cancers.
Impact on mental health
This experiment will investigate how the physical and cognitive impact of utilising computer screens in microgravity. The research will study how pointing tasks, gaze fixation and rapid eye movements are affected.

Cardiologist reveals the simple sleep habit that is his #1 recommendation for controlling blood pressure
Regulate circadian rhythm Lower overnight cortisol levels Improve heart rate variability Support blood pressure regulation The Science Behind Sleep and Hypertension Not Just About More Hours in Bed A Clock-Based Habit With Big Payoffs You Might Also Like: Whole plant-based proteins can slash high blood pressure risk, but new study reveals a crucial catch When it comes to managing blood pressure, most people immediately think of diet, exercise, or medication. But according to US-based cardiologist Dr. Sanjay Bhojraj , one of the most overlooked remedies could be as simple as watching the clock before a recent Instagram post, Dr. Bhojraj shared that sleep consistency plays a critical role in regulating blood pressure. 'Most people think blood pressure control is all about diet and exercise. But here's something I tell every patient: your sleep schedule matters just as much,' he number one recommendation? Go to bed and wake up at the same time every day — even on weekends. While it may sound basic, the cardiologist explained that the payoff can be significant. A stable sleep routine helps:'It's not even necessarily about more sleep; it's about consistent sleep,' Dr. Bhojraj added. 'That consistency tells your body when to rest, when to repair, and when to regulate blood pressure.'Dr. Bhojraj's advice is echoed by guidance from the Mayo Clinic , which warns that chronic sleep deprivation can be a direct contributor to high blood pressure. Adults are advised to aim for seven to nine hours of sleep each night, while those who consistently sleep fewer than six hours may face a greater risk of note that poor sleep disrupts hormone balance, increases stress, and can lead to weight gain and diabetes — all risk factors for heart disease. Conversely, consistent and restorative rest allows the body to regulate stress hormones and metabolism, which supports long-term cardiovascular health Interestingly, Dr. Bhojraj stressed that blood pressure benefits are less about increasing the number of hours slept and more about setting a routine. 'You really don't need to oversleep to compensate,' he noted. Too much sleep, in fact, has its own downsides, such as raising blood sugar levels and promoting weight like obstructive sleep apnea also complicate the picture. The Mayo Clinic cautions that the disorder, which causes interrupted breathing at night, is a hidden but common factor behind both poor sleep and high blood Bhojraj, founder of the wellness program Well12, emphasizes a holistic approach to heart health that goes beyond prescriptions. While nutrition, exercise, and stress management are central pillars, he believes sleep deserves equal advice is refreshingly simple: pay attention to your clock. Whether you're managing hypertension or just trying to lower your long-term risk, going to bed and waking up on schedule may be one of the most effective — and underrated — tools available.

ICAR-KVK Longding introduces milky mushroom cultivation
Itanagar: The Indian Council of Agricultural Research-Krishi Vigyan Kendra (ICAR-KVK) Longding has successfully introduced milky mushroom cultivation for the first time in Longding district. A team of scientists led by ICAR-KVK Longding senior-scientist and head Uttpal Kumar Bhattacharya and plant protection subject matter specialist Deep Narayan Mishra introduced the cultivation of milky mushroom (calocybe indica). The Kanubari-based KVK helped the farmers to adopt new technologies and was guided by Mishra in proper cultivation practices. Explaining the cultivation process, Bhattacharya said it starts with well-composted and pasteurised paddy straw or similar substrate, which is layered with spawn in polythene bags Within 15-20 days, the mycelium completely colonises the substrate. After colonisation, a casing mixture of vermicompost, river sand, and slaked lime in the ratio of 3:1:0.5 is applied, sterilised by autoclaving for one hour at 121°C to maintain hygiene and prevent contamination, he said. Bhattacharya said the casing layer initiates fruiting, with pinheads emerging in 7-10 days, and mushrooms ready for harvest within 30-35 days of spawning. Each bag yields multiple flushes for up to 45-50 days, making it a sustainable enterprise, he said adding, milky mushroom offers farmers a profitable alternative to oyster mushrooms due to its high yield potential (800-1000g per kg of dry substrate), longer shelf life (4-5 days at room temperature, longer under refrigeration), and premium market value. He said farmers are taking keen interest in milky mushroom cultivation as they can earn Rs 250-300 per kg, making it a lucrative income source. Additionally, milky mushroom stands out for its nutritional richness-packed with protein (3-4%), dietary fiber, B-complex vitamins, vitamin C, and essential minerals such as calcium, iron, phosphorus, potassium, and zinc, Mishra said. It is low in fat and cholesterol-free and is considered a functional food ideal for health-conscious consumers. Its adaptability makes it especially suitable for the rainy season (April–Oct) when warm and humid conditions (25–35°C) naturally favour its growth. Mishra said the seasonal advantage ensures reliable production with minimal environmental control. With continuous guidance and training programmes, farmers are now expanding into year-round mushroom cultivation, diversifying into milky, button, and oyster mushrooms, thereby enhancing both livelihood opportunities and community nutrition security.

Shubhanshu Shukla Shows Pics Of Earth From Space During Meet With PM Modi
New Delhi: Prime Minister Narendra Modi met Group Captain Shubhanshu Shukla this evening, a day after the astronaut returned to India after his historic visit to the International Space Station (ISS). PM Modi hosted Mr Shukla at the Prime Minister's residence in Delhi. PM Modi was seen welcoming Mr Shukla, who was wearing an ISRO astronaut's jacket, with a hug. He gifted the Axiom-4 mission patch to PM Modi and showed him pictures of the Earth taken from the International Space Station. He is the first Indian astronaut to travel to the International Space Station (ISS). "India is proud of his feat," posted PM Modi on X after the meeting. Had a great interaction with Shubhanshu Shukla. We discussed a wide range of subjects including his experiences in space, progress in science & technology as well as India's ambitious Gaganyaan mission. India is proud of his feat. @gagan_shux — Narendra Modi (@narendramodi) August 18, 2025 Mr Shukla was part of the Axiom-4 private space mission, which lifted off from Florida on June 25 and docked at the ISS on June 26. He returned to Earth on July 15. During the 18-day mission, Mr Shukla, along with astronauts Peggy Whitson (US), Slawosz Uznanski-Wisniewski (Poland), and Tibor Kapu (Hungary), conducted more than 60 experiments and 20 outreach sessions aboard the ISS. On Saturday, he posted on Instagram a photo of himself sitting on a plane. "As I sit on the plane to come back to India, I have a mix of emotions running through my heart. I feel sad leaving a fantastic group of people behind who were my friends and family for the past one year during this mission. I am also excited about meeting all my friends, family and everyone in the country for the first time post mission. I guess this is what life is -- everything all at once," read his post. "Having received incredible love and support from everyone during and after the mission, I can't wait to come back to India to share my experiences with all of you. Goodbyes are hard, but we need to keep moving in life. As my commander Peggy Whitson fondly says, 'the only constant in spaceflight is change'. I believe that applies to life as well," he said. Recalling the song from the Bollywood movie ' Swades ' that was on his playlist just before he embarked on the Axiom-4 mission from the US, Mr Shukla said, "I guess at the end of the day -' Yun hi chala chal rahi - jeevan gaadi hai samay pahiya '".
