I think we'd be past "jobs" if it were possible to store and read memory in DNA with the human brain.

Then who would be in charge of creating new knowledge, and who would put it into our brains or DNA? Knowing everything humans have discovered so far would only change the type of jobs we would have, we would still need to have jobs though.

Hence the quotations, we'd be past the traditional 9 to 5 and in pursuit of loftier ambitions.

Does anybody know how to escape their horrible "mobile" version that they force onto ipad users? It can't even be zoomed :-(

More and more often I find myself not reading articles because someone thought it would be a great idea to create a non-scrolling, non-obvious, paginated "iPad format" with additional misleading and unintuitive buttons looking like native ones but doing something different.

Sorry for the rant.

EDIT: so you might as well access the original at http://hms.harvard.edu/content/writing-book-dna instead of the ad-ridden regurgitation.

I notice that the article fails to mention how long it would take to extract all 700 terabytes of data... Assuming 5.5 petabits stored with 1 base pair representing 1 bit, we can extrapolate the time required to extract the data based off the time taken to sequence the human genome (3 billion base pairs). 5.5 petabits / 3 billion bits ~= 2 million, so theoretically it should take 2 million times longer to sequence th…

Hmm. DNA is fairly easy to duplicate though, right? Wouldn't that allow an exponential speedup?

I assumed that the microfluidic chip speed listed would include parallel processing.

Even if it doesn't, you'd still need something like 5,000 experiments in parallel for it to take less than a month...

This article is incredibly misleading. First of all there is an inconsistency. The headline says they stored 700 terrabytes (4.4 petabytes). It then later says that they actually stored 700 kilobytes (Their book) and that they did made 70 billion copies (44 petabytes?). The main thing is that storing 700 kilobytes and then making 700 billion copies is considerably less useful than storing 70 billion terabytes outright. Aside from that though, this is awesome, and a huge step forward into promising and uncharted territory.

On android there is "request desktop version" button in chrome. Maybe there is something similar for ipads?

I'm considering buying an iPad, and I have a question: is there no browser on the iPad that allows you to choose whether you want to the mobile version or the regular version? If not, that's almost a deal breaker.

If you store data onto 50 DNA strands, can you always read back all the data from all 50 strands, or does one need to store multiple copies of each in case the sequencer can't "find" a particular strand? If one does need multiple copies, it would seem that this method suffers from the coupon collector's problem [1] (i.e. to collect all 50 strands requires collecting 225 random strands on average), and that the retrie…

HN formatting breaks the first Wikipedia link by removing the apostrophe. I ran it through a link shortener as a workaround.

But you can also embed interesting information into an image without distorting the image itself (much). Similarly, the DNA of most organisms have a ton of garbage space that could be used to encode information without hurting the organism. Not saying it's practical or desirable, just that it is possible.

Leads me to wonder if the current "garbage" sequences in our own DNA could be encoded information that we were meant to decode - and by that I mean that that information may not just be entirely genetic code.

That's some seriously astute extrapolation! Nice idea, friend.

Yes those browsers are available. Chrome has a "request desktop site" option and my personal favourite, iCab Mobile, has an extensive list of agent strings (custom ones can be added as well) that can be set.
