WTF Fun Fact 13539 – Research in Space

The future of ophthalmology could be in the stars, quite literally – LambdaVision, a groundbreaking company, is exploring research in space.

The company is testing the outer limits of medical science by developing a synthetic retinal implant. This innovation could revolutionize treatment for degenerative eye diseases. Their method involves the intricate layering of bacteriorhodopsin, a light-reactive protein, to mimic the retina’s function.

Artificial Retina Research in Space

This delicate process, termed “layer-by-layer deposition,” traditionally involves transitioning a gauze piece through multiple solutions hundreds of times. The challenge? Sedimentation, evaporation, and convection significantly impact the formation of these vital thin films.

Wagner believes the microgravity environment of the International Space Station (ISS) could be the solution. In space, the absence of these earthly constraints allows for more precise film formation.

On April 27, 2023, SpaceX’s Crew Dragon spacecraft, bearing the experimental setup for LambdaVision’s synthetic retina, docked with the ISS. This venture was part of NASA’s Crew-4 mission’s extensive scientific agenda.

The Crew-4 team, consisting of NASA astronauts Kjell Lindgren, Robert Hines, and Jessica Watkins, alongside ESA astronaut Samantha Cristoforetti, engaged in various experiments over their six-month mission. Their tasks ranged from studying microgravity’s effects on the human nervous system to trialing innovative plant growth technologies.

One experiment that stands out is the Beat project, a brainchild of the German Space Agency. It involves astronauts wearing smart shirts embedded with sensors to monitor vital signs like heart rate and blood pressure.

Manufacturing the Future in Microgravity

Dr. Wagner envisions manufacturing the synthetic retinas on the ISS or future commercial space stations. This approach could significantly enhance the quality and functionality of these implants.

LambdaVision is still a few years away from clinical trials, but the work conducted on the ISS could expedite this timeline.

If successful, their space-manufactured synthetic tissues could restore sight for individuals suffering from conditions like retinitis pigmentosa or macular degeneration.

Implications and Aspirations of Research in Space

LambdaVision’s ambitious project is more than a scientific endeavor; it’s a beacon of hope for those grappling with vision loss. Their success could pave the way for more space-based biomedical manufacturing, leading to breakthroughs in various medical fields.

The ISS becomes not just a research facility but a vital production center for advanced medical therapies.
