Scientists at Southampton store human genome on crystal for future revival

Researchers at the University of Southampton have successfully stored the entire human genome on a 5D memory crystal, a groundbreaking achievement that could potentially allow for the revival of humanity in the distant future. This innovative data storage method can endure for billions of years without degradation, making it suitable for preserving the genetic information of endangered species as well. The crystal, which can hold up to 360 terabytes of data, is designed to withstand extreme temperatures, cosmic radiation, and significant impact forces, ensuring its longevity. The team, led by Professor Peter Kazansky, utilized ultra-fast lasers to inscribe data into nano-structured voids within silica, employing a unique encoding method that incorporates both optical dimensions and spatial coordinates. This advanced technique allows for a more efficient storage solution compared to traditional methods. Although current technology does not permit the synthetic creation of complex organisms, the stored genetic information could be invaluable if future advancements enable such processes. The 5D memory crystal has been placed in the Memory of Mankind archive, located in a salt cave in Hallstatt, Austria, serving as a time capsule for future generations or potential intelligent beings. The design of the crystal includes a visual key that provides insight into the data it contains, including the fundamental elements of DNA and its structure. This foresight reflects the researchers' consideration of how their work might be interpreted by future discoverers. Ultimately, this project not only aims to preserve human genetic material but also opens avenues for the conservation of biodiversity by recording the genomes of endangered species. The implications of this research could reshape our understanding of genetic preservation and restoration in the face of extinction.
