Q & A

What is the primary concern regarding data storage in today's society?

The primary concern is the exponential growth of stored data, which consumes massive resources and energy, contributing significantly to greenhouse gas emissions.

What percentage of stored files are considered 'cold data' and what does that mean?

It is estimated that 60 to 80% of stored files are 'cold data,' meaning they are rarely accessed or used, such as old emails or legal documents.

What inspired researchers to consider DNA as a storage medium?

Researchers were inspired by the compact and efficient storage of genetic information in living organisms, particularly how DNA encodes vast amounts of information in a very small space.

How does DNA storage compare to traditional data storage methods in terms of capacity?

DNA storage is significantly more compact, capable of storing data 100 million times denser than traditional hard drives, potentially allowing for all the world's data to fit in a shoebox.

What are the steps involved in storing information on DNA?

The steps include encoding the data into a quaternary format, synthesizing the DNA molecule, and finally isolating the DNA to protect it from degradation.

What are the challenges associated with reading data stored in DNA?

The challenges include the introduction of errors during the sequencing process, which necessitates storing multiple copies of the same DNA strands to cross-check information.

What is the estimated cost and speed of synthesizing DNA data storage as of 2024?

As of 2024, synthesizing DNA data storage costs around $1,000 per megabyte and takes about 2 minutes to write a single nucleotide, which is significantly slower than traditional storage methods.

What is the goal of the exploratory P molecule archive program?

The goal of the program is to explore and develop molecular data storage techniques, including improving synthesis methods and establishing standards for data structure.

How are researchers addressing the issue of file compression in DNA storage?

Researchers are working on strategies for compressing files, especially images, as they make up a large portion of stored data, and are involved in defining image compression standards specific to DNA.

What innovative applications of DNA technology are being researched beyond data storage?

Innovative applications include creating DNA computers, which use enzymes and DNA strands to perform calculations, and using artificial DNA as a marker for tracing stolen items.
