Human-beings have always been fond of accessing more and more information in minimum possible time and space. Consequently New Generation Computers and High Speed Internet have gained popularity in the recent years. We have been witness to remarkable achievements like the transition from the bulky hard-drives to the flash drives which has made personal data storage efficiently manageable. But when it comes to handling big data, the data of a corporation or of the world as a whole, the present data storage technology comes nowhere near to be able to manage it efficiently. An urgent need for a proper medium for information archival and retrieval purposes arises. Deoxyribonucleic acid (DNA) is seen as a potential medium for such purposes, essentially because it is similar to the sequential code of 0's and 1's in a computer. This field (DNA Computing) has emerged to become a topic of interest for researchers since the past decade, with major breakthroughs in its course. Seeming to come straight out of science fiction, "a penny-sized device could store the entire information as the whole Internet". The analyzed data from the researches reveals that just four grams of DNA can store all the information that the world produces in a year. Here, this topic of 'Data Storage in DNA' is described starting from the very first research to the most recent one, their techniques, their advantages and their flaws, the need for DNA storage, and how it will ultimately become a paradigm shift in computing.
Non-fungible tokens (NFTs)} are digital objects that reside on blockchains and are typically associated with unique digital media, such as images or music. A recent frenzy of popular interest has given rise seemingly overnight to a multi-billion NFT market. Individual NFTs can sell for millions or tens of millions of dollars, while creators ranging from traditional artists such as Damien Hirst and Grimes to mainstream consumer-goods companies such as Coca-Cola and Nike are producing their own NFT collections.This primer’s focus is on NFTs for art and collectables. Our aim is to give non-technical readers a basic familiarity with the technology behind NFTs, the history of their development, the current state of the NFT community and marketplace, and a notion of how NFTs might evolve in the future. We also offer a brief overview of the dynamics of traditional art markets and discuss the similarities, differences, and points of intersection in NFT markets. We hope that readers will come away from this primer with a basic understanding of how blockchains, smart contracts, and cryptographic keys work, an appreciation of some of the novel ways in which NFTs are empowering artists, a picture of the variety of dynamism of NFTs projects and communities, and possibly a hankering to own at least a fractional Bored Ape.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
