Bacteria Colonizes Asteroid Sample, Life's Left-Handed Mystery, and Zipf's Law in Languages
Dec 2, 2024
Earth bacteria shocked scientists by colonizing asteroid samples, challenging containment methods and our understanding of microbial life in space. A study reveals that RNA’s left or right-handed preferences might not be as fixed as once thought, shifting our view on how life developed. Meanwhile, Zipf's Law reveals a consistent pattern in language frequency that transcends cultures, offering insights into human cognition and potential advancements for AI language processing. These findings open new doors to both biology and linguistics.

Microbial Colonization of Asteroid Samples
Research on Earth bacteria colonizing samples from the asteroid Ryugu demonstrates the adaptability of terrestrial organisms to extraterrestrial materials. Scientists observed a rapid increase in microbial population from 11 to 147 within weeks of the samples' exposure to Earth's atmosphere, highlighting the challenges faced in studying pristine extraterrestrial materials. The study confirmed that contamination took place after rigorous containment measures, as shown through nano X-ray scans indicating the samples were initially microbe-free. This situation emphasizes the need for advanced containment protocols in future space missions to prevent microbial colonization and enhance the search for biological signatures on other celestial bodies.
