Researchers at Microsoft and the University of Washington have set a new record for DNA storage. The pair was able to record 200 megabytes of data on the molecular strands. Once encoded, the data was smaller than the tip of a pencil. How does storing digital data on DNA work? The data is translated from binary into the “letters” of the four nucleotide bases of a DNA strand. Twist Bioscience, a startup that makes and uses synthetic DNA to store digital data, then translates the letters into actual molecules and sends them back to a computer. Researchers read the data through RAM and use a polymerase chain reaction (PCR) to multiply or “amplify” the strands it wants to recover. Researchers can... Read more...
This week brought news of two advances in nanotechnology that could bring us ever-smaller devices with ever-increasing capacity.One brought us transistors a mere fraction of the size of most the advanced currently used on silicon chips. The other gave us the ability to store 250 DVDs worth of data on the area the size of a U.S. quarter.First, the transistors:A team from the University of Pittsburgh, led by Jeremy Levy, "created its nanotech transistors using two ceramic crystal materials known as lanthanum aluminate and strontium titanate. When sandwiched together, these natural insulators conduct electricity as a positive charge is passed across them."The big deal is that this is the first time... Read more...
