So Singh purchased the most powerful UV-C lamp he could find online, capable of sending out 20 times more radiation than the amount expected on Mars. When he tested the lamp on the most radiation-resistant life form on Earth, the bacterium Deinococcus radiodurans, it died in less than a minute. After 3 months—likely the highest amount of UV-C radiation ever tested on an organism—Singh pulled the sample so he could finish his master's thesis in time. About half of the lichen's algal cells had survived. Then, when the team ground up and cultured part of the surviving lichen, about half of its algal cells sprouted new, green colonies after 2 weeks, showing it maintained the ability to reproduce. , UV-C light kills nearly everything—except this unusual organism Built-in Sun protection might be a blueprint for surviving in space, UV-C Light Kills Nearly Everything - Except This Unusual Organism (science.org) 27 Posted by EditorDavid on Monday June 30, 2025 @07:34AM from the catching-some-rays dept..
A type of lichen was able to survive extreme UV radiation in the lab, suggesting that ozone protection might not be required for life on exoplanets., Ultraviolet light, the type that gives us sunburns, comes in three forms: UVA, UVB, and UVC. Earth’s atmosphere filters out nearly all of the deadly UVC rays before they reach the surface, leaving life to evolve in relative safety., Ultraviolet C (UVC) light is widely used for its germicidal properties, particularly in disinfection. While it effectively inactivates bacteria and viruses, concerns about safety and health risks have emerged. Understanding its effects and limitations is essential for informed use., Dozens of labs began testing Far-UVC light against coronaviruses, studying its effects in rooms and public spaces. The promise of continuous, human-safe, airborne disinfection became not just intriguing — but necessary., UVC light is a constituent of the electromagnetic spectrum found in the region between x-ray and visible light. It was established a long time ago that UV-C light is germicidal hence its ability to deactivate the DNA of microorganisms such as viruses, bacteria, and other pathogens., .
