Geneticists can store data in synthetic DNA as a medium for long-term storage due to its density, ease of copy, longevity and sustainability. Research in the field had recently advanced with new encoding algorithms, automation, preservation and sequencing. Nevertheless, the most challenging hurdle in DNA storage deployment remains the write throughput, which can limit the data storage capacity. In a new report, Bichlien H. Nguyen, and a team of scientists in Microsoft Research and computer science and engineering at the University of Washington, Seattle, U.S., developed the first nanoscale DNA storage writer. The team intended to scale the DNA write density to 25 x 106 sequences per square centimeter, an improved storage capacity compared to existing DNA synthesis arrays. The scientists successfully wrote and decoded a message in DNA to establish a practical DNA data storage system. The results are now published in Science Advances. https://phys.org/news/2021-12-dna-storage-nanoscale-electrode-wells.html
From Dr. Vernon Coleman Earth Newspaper – A Major Source of Information If you’re looking for a cache of information about covid-19 I suggest you take a look at EarthNewspaper.com which contains over 2,250 articles about covid-19 – it is said to be the largest archive of covid-19 articles and videos online and I believe it. We are fighting a war and EarthNewspaper.com is a valuable asset in the war – an asset too often under-estimated. The site’s tagline is `All the Honest News Fit to Publish’.
