AEROSPACE DENTISTRY Reflecting on today's historic 'civilian spacewalk' in The Times. online article today - it noted 19 people are currently living off planet earth, many on prolonged missions. It got me thinking, what is the impact of zero gravity on astronauts’ oral health, some of whom may be packing their toothbrush for a future trip to Mars. Aerospace dentistry a new speciality, "focuses on developing innovative technologies and approaches to address oral health challenges associated with long-duration space missions, lunar bases, and future Mars missions. Studies are conducted either in spaceflights or in a simulated microgravity environment". Space-flight induced changes include bone resorption which can effect the jaw, while muscular atrophy can affect gland function and secretion, reducing salivary flow. Altered immunity due to radiation and disrupted sleep can increase the virulence of the oral microbiome - comparative studies indicated and increase of anaerobic bacteria in-between the teeth in astronauts while in space - bad news for gums! "Advances in tele-dentistry, incorporating AI algorithms and wearable devices to monitor astronauts during missions continuously will allow real-time consultation with dental professionals." Interesting to note tele-dentistry, salivary diagnostics, AI toothbrushes and dental monitoring cameras for use on your phone, are also deployed here on earth! My next mission is to get #Toothboost Oral Mist into orbit 🚀 👩🚀 watch this outer-space! Thanks is given to Divya Harika et al for their recently published review as cited: - A fascinating read.

🌌 Innovating Space Medicine by Advancing Medical Imaging Techniques; Insights from other Institutions At the Center for Space Medicine Research (CSMR) we investigate tools like medical imaging to safeguard astronaut health across all mission stages. It’s why we were excited to see the recent publication by Michael Pohlen MD UC San Diego Health, as it dives into novel imaging techniques—like portable MRI and cone-beam CT—designed to overcome the unique challenges of microgravity and remote care. These approaches look to optimize astronaut health from preflight to post-mission. Inspiring work. With years of expertise, several CSMR researchers have worked with NASA - National Aeronautics and Space Administration, German Aerospace Center (DLR), and other space agencies on studies that deploy portable imaging devices to monitor brain activity. The value here is to build on existing work to push the limits, pioneer new approaches and advocate for solutions that employ magnetic resonance imaging, radiology, or computed tomography to ensure resilience in extreme and novel environments…be it in outer space or here on Earth! It's work like this paper that we aim to learn from and continue to build on for rapid progress. Every advancement in space radiology translates to insights that improve healthcare for everyone. Everywhere. How do you think we can leverage advances in imaging for astronauts and those of us who won’t travel to space?

1/2.Title: Electromagnetic Field Management in Traffic Guidance: Applications in Automobiles, Satellites, and Space Communication Biophysics and Atomic Clutter in Space Communication: 1. Atomic Clutters and Safety Hazards: In space, where atomic structures behave differently due to low gravity, the presence of multiple electromagnetic fields can cause what is known as atomic clutter. This occurs when atoms and electrons from different sources interact, causing interference that affects both communication and operational systems. In space stations, where multiple engines, computers, and communication systems are in close proximity, managing these fields becomes crucial to avoid operational failures or accidents. Biophysics offers valuable insights into the management of these fields. By studying how biological systems like the human body interact with electromagnetic fields, scientists can develop better protective systems for astronauts and space station equipment. Electromagnetic field shielding, for example, can protect sensitive equipment from the harmful effects of atomic clutter, ensuring the continued operation of critical systems. 2. Electromagnetic Fields in Biological Systems: The study of biophysics has revealed that biological systems are sensitive to electromagnetic fields. In space, where the Earth’s magnetic field is weaker, astronauts are exposed to higher levels of cosmic radiation and electromagnetic interference. These fields can have a profound impact on human biology, affecting everything from cellular metabolism to mental health. By understanding the interaction between electromagnetic fields and biological systems, engineers can design spacecraft and space stations that minimize these effects, keeping astronauts safe and healthy during long-term missions.

How are #organsonchips advancing space exploration? 🌌🚀 Instead of rocketing animals into space, these human biology-based models provide accurate data for understanding and mitigating the effects of #microgravity on the human body. https://lnkd.in/g5dCiGsw In a study published last month in PNAS, Devin Mair; Jonathan Tsui, PhD; Deok-Ho Kim; and colleagues at Johns Hopkins Biomedical Engineering sent human bioengineered heart tissue to the International Space Station with Jessica Meir for 30 days and were able to collect real-time data on the cells' function (https://lnkd.in/gY3cX2hC). Their results showed that low gravity conditions exerted stress on human heart cells and increased arrhythmias, mimicking effects observed in astronauts after space travel (https://lnkd.in/gCW7AT2h).    In another study, Soochi Kim, Bugra Ayan, Mahdis Shayan, Thomas Rando, and Ngan Huang of Stanford University found that engineered human muscle tissue kept at the Space Station showed characteristic reductions in muscle regeneration, effects that could be partially reversed.
