Comment Re:This could make possible a new type of virus (Score 1) 57

A virus needs DNA (or RNA) and a protective shell that helps protect and deliver it's payload. Here there's no shell.

Also, any commercial hardware and all research hardware i know of would encrypt the data before writing to prevent this from happening intentionally. No implemented encryption scheme is perfect but it would be far easier to just order your "virus" DNA with a credit card then it would be to hack a DNA hard drive that only makes DNA a 100-200 bases long.

Comment Re:Millions of times faster? (Score 1) 57

Actually I think that millions of times faster statement in the summary came from a misquote or misunderstanding. For archival storage(write once read VERY seldom). It should have been millions (or trillions really) more bytes. 20 hours to write an archive and 1 hour to read it isn't bad. I believe amazon glacier has a similar read latency.

Comment Re:Why DNA? (Score 2) 57

This is an excellent question! In principle any (hetero)polymer would work.

For context, in the short term we're targeting archival storage and not high speed storage (it'll probably never be low latency in the same way an SRAM is). The amazing thing about DNA is that it's not only long lived under reasonable storage conditions but also eternally relevant. Try reading a 30 year old 8" floppy today. The data may still be okay but you'll have trouble finding the hardware. Since DNA is so important to humans in other contexts (medicine), we can be fairly certain that DNA reading (sequencing) will be easy and available in 30 years, or 300, or 3000.

DNA is also much easier to manipulate. Nature provides us with all the tools (enzymes) we need to copy and select specific sequences. Academia provides us with a better understanding of DNA than other polymers. And industry provides us with wonderful machines like high throughput DNA sequencers. Watson-Crick base paring also allows DNA to do computation, which in some cases can be done directly on the data encoding DNA.

As for safety, you are right in that many microbes are quite good at finding and incorporating DNA but such an even would still be quite rare and there are many things to consider:
1) DNA data payloads are stored as just DNA, typically frozen or dried. And DNA alone is not sufficient to be pathogenic.
2) Generally when scientists store data in DNA right now it's encrypted first. This make it hard to pick out payload data that will encode for something specific.
3) It's far easier for a malicious person to just get parts of genes synthesized from different vendors and stitch them together at home. That ship has already sailed.
4) Currently the best way to synthesize the data payloads is in short sequences of DNA that aren't long enough to encode for anything but short peptides.
5) Randomly coming across a working pathogenic DNA sequence is technically possible but practically impossible (much like it's possible that you'll spontaneously quantum tunnel to the center of the earth but that'll never actually happen). An average gene in e. coli is about 8000 bases long. Of that size alone there are 4^(8000) (a beyond astronomically large number) of DNA sequences and only a handful of those do anything at all. Of those most would be toxic to the microbe it self or be a useless metabolic load (proteins are expensive to make and useless genes get cut out or turned off VERY fast in a population---days in continuous culture).
6) If desired, you can also trade off a little density to insert stop codons occasionally, limiting the size of anything translated to only a few amino acids.

Comment why not a record then? (Score 1) 440

Saying tape has a longer life is silly. I'd have no idea where to get an 8-track player today even though it's an analog format.

Same with a record player, but I could make one pretty easily. (there's a reason why we shot a record into space instead of a tape)

Really, though a documented and uncompressed digital file, properly kept track of, could last forever similar to a record even if we lost our codecs it would be easy to write a new one.

Comment Re:Hmmm... could this be a solution...? (Score 1) 92

Other respondents to this comment pointed out that these are fluorescent (ie need an excitation light source) not "glowing".

But another problem with this idea is that, in a population neutral alleles maintain their frequency (though can drift randomly) and deleterious alleles will decline in frequency. In other words, you'd have to release a LOT of rabbits before the glowing allele would be common enough to have an effect on average fitness and that allele would be unstable in the population. Unless you don't believe in evolution, but then you're better off praying for the rabbits to go away.

Submission + - Bell Labs Break Record with 31Tbps via a Single 7200km Optical Fibre (ispreview.co.uk)

Mark.JUK writes: Alcatel-Lucent's research and development division, Bell Labs, has successfully broken yet another record after it used 155 lasers (each operating at different frequencies and carrying 200Gbps of data over a 50GHz frequency grid) and an enhanced version of Wavelength Division Multiplexing (WDM) to send information at a staggering speed of 31 Terabits per second over a single 7200km long optical fibre cable. Previous experiments have been faster but only over shorter distances or by using a different type of fibre optic cable entirely.

United States Begins Flying Stealth Bombers Over South Korea 567

skade88 writes "The New York Times is reporting that the United States has started flying B-2 stealth bomber runs over South Korea as a show of force to North Korea. The bombers flew 6,500 miles to bomb a South Korean island with mock explosives. Earlier this month the U.S. Military ran mock B-52 bombing runs over the same South Korean island. The U.S. military says it shows that it can execute precision bombing runs at will with little notice needed. The U.S. also reaffirmed their commitment to protecting its allies in the region. The North Koreans have been making threats to turn South Korea into a sea of fire. North Korea has also made threats claiming they will nuke the United States' mainland."

DOJ Often Used Cell Tower Impersonating Devices Without Explicit Warrants 146

Via the EFF comes news that, during a case involving the use of a Stingray device, the DOJ revealed that it was standard practice to use the devices without explicitly requesting permission in warrants. "When Rigmaiden filed a motion to suppress the Stingray evidence as a warrantless search in violation of the Fourth Amendment, the government responded that this order was a search warrant that authorized the government to use the Stingray. Together with the ACLU of Northern California and the ACLU, we filed an amicus brief in support of Rigmaiden, noting that this 'order' wasn't a search warrant because it was directed towards Verizon, made no mention of an IMSI catcher or Stingray and didn't authorize the government — rather than Verizon — to do anything. Plus to the extent it captured loads of information from other people not suspected of criminal activity it was a 'general warrant,' the precise evil the Fourth Amendment was designed to prevent. ... The emails make clear that U.S. Attorneys in the Northern California were using Stingrays but not informing magistrates of what exactly they were doing. And once the judges got wind of what was actually going on, they were none too pleased:"

Google Pledges Not To Sue Any Open Source Projects Using Their Patents 153

sfcrazy writes "Google has announced the Open Patent Non-Assertion (OPN) Pledge. In the pledge Google says that they will not sue any user, distributor, or developer of Open Source software on specified patents, unless first attacked. Under this pledge, Google is starting off with 10 patents relating to MapReduce, a computing model for processing large data sets first developed at Google. Google says that over time they intend to expand the set of Google's patents covered by the pledge to other technologies." This is in addition to the Open Invention Network, and their general work toward reforming the patent system. The patents covered in the OPN will be free to use in Free/Open Source software for the life of the patent, even if Google should transfer ownership to another party. Read the text of the pledge. It appears that interaction with non-copyleft licenses (MIT/BSD/Apache) is a bit weird: if you create a non-free fork it appears you are no longer covered under the pledge.

Its naive to think that buses are only good for storage.
1080p video is 1080*1920pixels/frame*32bits/pixel*60frames/second is roughly 4Gb (uncompressed). If history is any indication displays will get larger and denser (also remember bandwidth needed will scale by the square of the number of lines). Or what if you want an external GPU? 16x pci express is about 32Gbits/sec. Also more speed reduces latency, which may be helpful too depending on what you use it for.
