A trip to Mars could damage an astronaut’s kidneys, experts say London: Although we know that the absence of water and oxygen cannot support human life on Mars, the effects on our bodies far outweigh these problems. We know that astronauts’ bones and muscles weaken due to space travel and the lack of gravity, while cosmic radiation increases their risk of cancer and affects the immune system. Now scientists have discovered that it can also damage the kidneys. Research conducted by a team of kidney specialists at University College London recently published their report in the journal Nature, showing that long-duration spaceflight can permanently damage human kidneys, even That an astronaut going to Mars might have to be on dialysis upon return. Lead author Keith Siew said, “On Earth, we knew that radiation was so dangerous to the kidney that we took precautions before radiation therapy, but we’ve done a lot of research on kidney health in spaceflight.” did not pay attention to the effects of Keith and his team examined humans and mice that went to the International Space Station for various experiments. The researchers then looked at some experiments on Earth in which the kidneys of animals were exposed to radiation. In the results, the researchers found some major changes in the kidneys. They found that two proteins in the kidneys, which are responsible for processing calcium, became completely inactive. Second, they noted major changes in a part of the kidney called the distal convoluted tubule (DCT), which regulates sodium and blood pressure. DCT becomes smaller in space. This results in astronauts not only losing extra calcium from their bones, which weakens the bones, but it also causes problems with the kidneys filtering out the excess calcium, leading to Chances of kidney stones increase. #trip #Mars #damage #astronauts #kidneys #experts

Would astronauts’ kidneys survive a roundtrip to Mars?... New research from UCL finds space travel damages kidneys, raising concerns for Mars missions. Microgravity shrinks key areas & simulated Mars radiation harms kidneys in mice. Can astronauts survive long journeys without dialysis?

📌 'Space headaches' could be a real pain for astronauts! A recent study published in @Neurology® reveals that astronauts on long-haul space missions lasting more than 10 days may experience migraine and tension-type headaches, even if they had no prior history of headaches. Changes in gravity during space travel can impact various bodily functions, including the brain, leading to headaches as a common symptom, according to @W. P. J. van Oosterhout, MD, PhD, the study's author. The study involved 24 astronauts from different space agencies and found that 92% experienced headaches during spaceflight, compared to 38% before the flight. Of the total headaches, 90% were tension-type headaches, and 10% were migraine-like, with headaches being more intense during the first week of spaceflight. Post-flight, no astronauts reported headaches, indicating a temporary nature of space-related headaches. Further research is needed to understand the underlying causes and develop effective therapies for space headaches. While the study shows an association between space travel and headaches, it doesn't confirm causation.

It looks like any manned missions to Mars might be further away than we thought as recent modelling of the Kidneys in space has given unfavorable results. Shrinkage of the kidneys due to exposure to cosmic radiation and microgravity would mean that anyone who enjoyed the trip to Mars would likely only survive the trip back attached to a dialysis machine. New technologies and approaches will have to be developed based on these findings. #space #mars #biology https://lnkd.in/eXvQewuu

MITO NEWS: Exploring the Link Between Mitochondrial Dysfunction and Spaceflight-Associated Neuro-Ocular Syndrome (SANS): As we embark on the era of commercialized human spaceflight and plan for the 2030 Mars Mission, understanding the health challenges faced by astronauts is paramount. One such challenge is Spaceflight-Associated Neuro-Ocular Syndrome (SANS), impacting astronauts during long-duration spaceflight (LDSF). Current research by Joshua Ong, MD, Andrew Lee, Mouayad M. et al delves into the intriguing connection between SANS and mitochondrial dysfunction. Mitochondria, vital for energy production, play a crucial role in ocular health. Diseases like diabetic retinopathy and age-related macular degeneration are associated with mitochondrial defects. Advancing our understanding of the intricate mechanisms connecting mitochondrial function to SANS is crucial for developing effective countermeasures. Research into diagnostics, countermeasures, and lifestyle interventions will be pivotal in ensuring the well-being of astronauts on future long-duration space missions.

The Meteoric Rise of Space Biology in Malta Was discussing with Josef Borg and we came with this fitting title - wouldn’t you agree? Over the past few years, #Malta has been quietly making history in the realm of #space biology and bioscience establishing itself as a small but significant player in the global space community. Our journey started in 2021 with the ambitious MALETH program, which saw Maltese experiments launched to the International Space Station (ISS) not once, but three times in a row. These missions, conducted between 2021 and 2023, were a monumental achievement for our tiny island, proving that size is no barrier to innovation and scientific discovery. The MALETH program, a collaboration between Maltese scientists and international space agencies including ICE Cubes Service Christopher Mason Afshin Beheshti and many others , aimed to study how microgravity affects various biological and human skin tissue samples. The results from these missions are already shaping our understanding of life and #microbiomes in #space and contributing to the broader field of space medicine. For a nation as small as ours, participating in such high-profile space missions is nothing short of extraordinary 🙏 But our journey didn't stop there. Malta's involvement in space biology expanded further as we contributed to the success of several crewed flights. Among these were collaborations with #NASA & #JAXA where our groups and Maltese scientists played a key role in analyzing both samples and data from astronauts 👨🚀and studying the effects of space travel on the human body. One of the most notable projects was our participation in #SpaceX's inspiration4x mission—the world's first all-private, all-civilian spaceflight - thanks to Chris Mason and his team as part of the Springer Nature Group collection SPACE OMICS and MEDICAL ATLAS . The mission made headlines around the globe as a groundbreaking moment in space exploration. Here in #Malta, we had the unique privilege of testing the crew's blood for hemoglobin profiling, an essential part of understanding how space affects human health. This project highlighted Malta’s growing reputation as a center for space biology, demonstrating our ability to contribute to missions of global significance. As we continue to explore the final frontier, Malta’s star 🌟 is undoubtedly on the rise, shining brightly in the vast expanse of space ☄️

🚀 Space Travel and Gut Health: A New Frontier! Research using data from NASA GeneLab sheds light on how space travel affects our gut health. 🧑🚀 Space travel causes a significant shift in our gut microbiome: - Decrease in beneficial bacteria like Akkermansia and Bifidobacterium - Increase in potentially harmful bacteria like Citrobacter and Klebsiella This dysbiosis could lead to increased gut permeability - aka "leaky gut" 🧬 The study also found altered expression of key genes related to gut health: - Decreased expression of genes related to mucus production and tight junction proteins - Increased expression of inflammatory markers These changes suggest a compromised gut barrier during spaceflight. ⏱️ Duration Matters  Unsurprisingly, longer missions (60 days vs 28 days) showed more pronounced effects on the astronauts' guts. Who knows - maybe future missions will include specially designed "space probiotics"! #guthealth #microbiome #spacemedicine #astronauthealth #futureofspace #spase #injoy

Spaceflight effects tumor-bearing fruit fly hosts and their parasites: How does spaceflight affect tumor-bearing fruit fly hosts and their parasites? Background: Like humans, fruit flies (a model organism for spaceflight research) also exhibit immune system dysfunction in space. Despite decades of studies on fruit flies and wasps, little was known about how their immune systems interact with natural parasites in space. Drosophila parasitoid wasps modify blood cell […]
