Linguagens / Inglês / Text Comprehension / Find Specific Information in the Text

Scientists have long touted DNA’s potential as an ideal storage medium; it’s dense, easy to replicate, and stable over millennia. But in order to replace existing silicon-chip or magnetic-tape storage technologies, DNA will have to get a lot cheaper to predictably read, write,and package.
That’s where scientists like Hyunjun Park come in. He and the other cofounders of Catalog, an MIT DNA-storage spinoff emerging out of stealth on Tuesday,are building a machine that will write a terabyte of data a day, using 500 trillion molecules of DNA.
If successful, DNA storage could be the answer to auniquely 21st-century problem: information overload.Five years ago humans had produced 4.4 zettabytes ofdata; that's set to explode to 160 zettabytes (each year!)by 2025. Current infrastructure can handle only afraction of the coming data deluge, which is expected toconsume all the world's microchip-grade silicon by 2040.
“Today’s technology is already close to the physical limits of scaling,” says Victor Zhirnov, chief scientist of the Semiconductor Research Corporation. “DNA has an information-storage density several orders of magnitude higher than any other known storage technology.”
How dense exactly? Imagine formatting every movie ever made into DNA; it would be smaller than the size of a sugar cube. And it would last for 10,000 years.
