This Week in Tech

Storage shrinks.... to DNA size!

It has been a relatively quiet week (if you exclude product launches) in general tech news. So this week's blog is equally short - but it does contain one or two interesting snippets...

Storage

We know that storage keeps getting smaller, faster, cheaper. BUT, this typically relates to the 'working storage' that we use all the time whilst our devices are active. Backup storage needs RELIABILITY above all other factors as its main characteristic. Tapes, Hard drives, optical media... they all fall short when it comes to long term archiving and storage of data. The material itself degrades, the hardware and software used to read the media becomes obsolete and so, ironically, our age of data collection and accessibility might in the long term, possibly end up with fewer records than the written pages of the Middle Ages!

One of the efforts aimed at solving this problem is aimed at figuring out how to store data using DNA. Yep, that same stuff that holds the genetic encoding that makes you 'YOU'.

This week in the news saw scientists encode complete jazz songs onto DNA - Digital Trends has the article here. The company responsible - Twist BioScience - has and interesting blog explaining what they see as the need for and the potential of DNA storage here.

Cryptocurrency

The New York Times has a short 'Q&A' style article explaining what Bitcoin is and how it works. Worth a read if you don't understand cryptocurrencies...

Tattoo Sensors

The video says it all....

That's it for this week.
