Researchers at Berlin’s Technical University propose a groundbreaking method for extraterrestrial life detection by attracting microbes with L-serine, an amino acid. Instead of relying on complex instruments, they aim to observe motility as a simple biosignature. Their experiments showed extremophile bacteria moving towards the bait, confirming this approach’s potential. However, challenges remain, such as the unknown size and chemistry of alien microbes. Future tests will refine this system under Mars-like conditions, paving the way for more effective life detection missions.
Do you think motility is a reliable indicator of life? What alternative methods could enhance detection strategies?
