DNA Digital Data Storage

Researchers Store Computer Operating System and Short Movie on DNA
DNA is an ideal storage medium because it's ultra-compact and can last
hundreds of thousands of years if kept in a cool, dry place, as
demonstrated by the recent recovery of DNA from the bones of a
430,000-year-old human ancestor found in a cave in Spain. They compressed
the files into a master file, and then split the data into short strings
of binary code made up of ones and zeros. Using an erasure-correcting
, they randomly packaged the strings into so-called
droplets, and mapped the ones and zeros in each droplet to the four
nucleotide bases in DNA: A, G, C and T. The algorithm deleted letter
combinations known to create errors, and added a barcode to each droplet
to help reassemble the files later. They generated a digital list of
72,000 DNA strands, each 200 bases long. To retrieve their files, they
used modern sequencing technology to read the DNA strands, followed by
software to translate the genetic code back into binary. They recovered
their files with zero errors, the study reports. They also demonstrated
that a virtually unlimited number of copies of the files could be created
with their coding technique by multiplying their DNA sample through
polymerase chain reaction (PCR), and that those copies, and even copies of
their copies, and so on, could be recovered error-free. Finally, the
researchers show that their coding strategy packs 215 petabytes of data on
a single gram of DNA. The capacity of DNA data-storage is theoretically
limited to two binary digits for each nucleotide, but the biological
constraints of DNA itself and the need to include redundant information to
reassemble and read the fragments later reduces its capacity to 1.8 binary
digits per nucleotide base. The team's insight was to apply fountain
codes, a technique Erlich remembered from graduate school, to make the
reading and writing process more efficient. With their DNA Fountain
technique, Erlich and Zielinski pack an average of 1.6 bits into each base
nucleotide. That's at least 60 percent more data than previously published
methods, and close to the 1.8-bit limit. The researchers spent $7,000 to
synthesize the DNA they used to archive their 2 megabytes of data, and
another $2,000 to read it.
For 3 billion years, one of the major carriers of information needed for
life, RNA, has had a glitch that creates errors when making copies of
. Researchers at The University of Texas at Austin
have developed a fix that allows RNA to accurately proofread for the first
time. Certain viruses called retroviruses can cause RNA to make copies of
DNA, a process called
. This process is notoriously prone to errors
because an evolutionary ancestor of all viruses never had the ability to
accurately copy genetic material. The new innovation engineered at UT
Austin is an enzyme that performs reverse transcription but can also
"proofread," or check its work while copying genetic code. The enzyme
allows, for the first time, for large amounts of RNA information to be
copied with near perfect accuracy.
Molecular recordings by directed CRISPR spacer acquisition
The ability to write a stable record of identified
molecular events into a specific genomic locus would enable the
examination of long cellular histories and have many
applications, ranging from developmental biology to synthetic
devices. We show that the type I-E CRISPR-Cas system of E.
coli can mediate acquisition of defined pieces of synthetic DNA.
We harnessed this feature to generate records of specific DNA
sequences into a population of bacterial genomes. We then
applied directed evolution to alter the recognition of a
protospacer adjacent motif by the Cas1-Cas2 complex, which
enabled recording in two modes simultaneously. We used this
system to reveal aspects of spacer acquisition, fundamental to
the CRISPR-Cas adaptation process. These results lay the
foundations of a multimodal intracellular recording device.
Data Storage Device
is a device for recording (storing) information
(data). Recording can be done using virtually any form of energy, spanning
from manual muscle power in handwriting, to acoustic vibrations in
phonographic recording, to electromagnetic energy modulating magnetic tape
and optical discs. A storage device may hold information, process
information, or both. A device that only holds information is a recording
medium. Devices that process information (data storage equipment) may
either access a separate portable (removable) recording medium or a
permanent component to store and retrieve data. Electronic data storage
requires electrical power to store and retrieve that data. Most storage
devices that do not require vision and a brain to read data fall into this
category. Electromagnetic data may be stored in either an analog data or
digital data format on a variety of media. This type of data is considered
to be electronically encoded data, whether it is electronically stored in
a semiconductor device, for it is certain that a semiconductor device was
used to record it on its medium. Most electronically processed data
storage media (including some forms of computer data storage) are
considered permanent (non-volatile) storage, that is, the data will remain
stored when power is removed from the device. In contrast, most
electronically stored information within most types of semiconductor
(computer chips) microcircuits are volatile memory, for it vanishes if
power is removed. Except for barcodes, optical character recognition
(OCR), and magnetic ink character recognition (MICR) data, electronic data
storage is easier to revise and may be more cost effective than
alternative methods due to smaller physical space requirements and the
ease of replacing (rewriting) data on the same medium.

communication channels and signal processing operations, which can
progressively degrade the
(SNR), which is a measure used in science and
engineering that compares the level of a desired signal to the level of
background noise. It is defined as the ratio of signal power to the noise
power, often expressed in decibels. A ratio higher than 1:1 (greater than
0 dB) indicates more signal than noise. While SNR is commonly quoted for
electrical signals, it can be applied to any form of signal (such as
isotope levels in an ice core or biochemical signaling between cells).
is a system that converts an analog
signal, such as a sound picked up by a microphone or light entering a
digital camera, into a digital signal. An ADC may also provide an isolated
measurement such as an electronic device that converts an input analog
voltage or current to a digital number proportional to the magnitude of
the voltage or current. Typically the digital output is a two's complement
binary number that is proportional to the input, but there are other
possibilities. There are several ADC architectures. Due to the complexity
and the need for precisely matched components, all but the most
specialized ADCs are implemented as integrated circuits (ICs). A
digital-to-analog converter (DAC) performs the reverse function; it
converts a digital signal into an analog signal.
is a random fluctuation in an electrical signal, a
characteristic of all electronic circuits. Noise generated by electronic
devices varies greatly as it is produced by several different effects.
Thermal noise is unavoidable at non-zero temperature (see
fluctuation-dissipation theorem), while other types depend mostly on
device type (such as shot noise, which needs a steep potential barrier) or
manufacturing quality and semiconductor defects, such as conductance
fluctuations, including 1/f noise.

is the alteration of the original shape (or other
characteristic) of something, such as an object, image, sound or waveform.
Distortion is usually unwanted, and so engineers strive to eliminate
distortion, or minimize it. In some situations, however, distortion may be
desirable. The important signal processing operation of heterodyning is
based on nonlinear mixing of signals to cause intermodulation. Distortion
is also used as a musical effect, particularly with electric guitars.
refers either to a physical transmission
medium such as a wire, or to a logical connection over a multiplexed
medium such as a radio channel in telecommunications and computer
networking. A channel is used to convey an information signal, for example
a digital bit stream, from one or several senders (or transmitters) to one
or several receivers. A channel has a certain capacity for transmitting
information, often measured by its bandwidth in Hz or its data rate in
bits per second.
is an enabling technology that encompasses the
fundamental theory, applications, algorithms, and implementations of
processing or transferring information contained in many different
physical, symbolic, or abstract formats broadly designated as signals. It
uses mathematical, statistical, computational, heuristic, and linguistic
representations, formalisms, and techniques for representation, modelling,
analysis, synthesis, discovery, recovery, sensing, acquisition,
extraction, learning, security, or forensics.
refers to errors in computer data that occur during
writing, reading, storage, transmission, or processing, which introduce
unintended changes to the original data.
Entropy (information theory)
In information theory, systems are
modeled by a transmitter, channel, and receiver. The transmitter produces
messages that are sent through the channel. The channel modifies the
message in some way. The receiver attempts to infer which message was
sent. In this context, entropy (more specifically, Shannon entropy) is the
expected value (average) of the information contained in each message.
'Messages' can be modeled by any flow of information. The amount of
information of every event forms a random variable whose expected value,
or average, is the Shannon entropy. Units of entropy are the shannon, nat,
or hartley, depending on the base of the logarithm used to define it,
is commonly referred to as a bit.
refers to influences on effective
conversations. While often looked over, communication noise can have a
profound impact both on our perception of interactions with others and our
analysis of our own communication proficiency. Forms of communication
noise include psychological noise, physical noise, physiological and
semantic noise. All these forms of noise subtly, yet greatly influence our
communication with others and are vitally important to anyone’s skills as
a competent communicator.
is anything which modifies, or disrupts a signal as it travels along a
channel between a source and a receiver. The term typically refers to the
addition of unwanted signals to a useful signal. Common examples are:
Electromagnetic interference (EMI). Co-channel interference (CCI), also
known as crosstalk. Adjacent-channel interference (ACI). Intersymbol
interference (ISI). Inter-carrier interference (ICI). caused by doppler
shift in OFDM modulation (multitone modulation). Common-mode interference
(CMI). Conducted interference. Interference is typically but not always
distinguished from noise, for example white thermal noise. Radio resource
management aims at reducing and controlling the co-channel and
adjacent-channel interference. See also: Distortion,
Signal-to-Interference Ratio (SIR), Signal to noise plus interference (SNIR),
Inter-flow interference and Intra-flow interference.
Error Detection and Correction
are techniques that enable
reliable delivery of digital data over unreliable communication channels.
Many communication channels are subject to channel noise, and thus errors
may be introduced during transmission from the source to a receiver. Error
detection techniques allow detecting such errors, while error correction
enables reconstruction of the original data in many cases.
involves encoding information using fewer bits than the
original representation. Compression can be either lossy or lossless.
reduces bits by identifying and eliminating statistical
redundancy. No information is lost in lossless compression.
reduces bits by removing unnecessary or less
important information. The process of reducing the size of a data file is
referred to as data compression. In the context of data transmission, it
is called source coding (encoding done at the source of the data before it
is stored or transmitted) in opposition to channel coding.
