Because of their central importance to biology, proteins have been the focus of intense research, particularly the manner in which they are produced from genetically coded templates–a process commonly known as translation. While the general mechanism of translation has been understood for some time, protein synthesis can initiate by more than one mechanism. One of the least well understood mechanisms is known as cap-independent translation. Now, John Chaput and his colleagues at...

One approach to understanding components in living organisms is to attempt to create them artificially, using principles of chemistry, engineering and genetics. A suite of powerful techniques–collectively referred to as synthetic biology–have been used to produce self-replicating molecules, artificial pathways in living systems and organisms bearing synthetic genomes. In a new twist, John Chaput, a researcher at Arizona State University´s Biodesign Institute and colleagues...

Researchers Create Synthetic DNA/RNA That Can Evolve

Researchers have created artificial genetic material known as Xenonucleic acids, or XNAs, that can store information and evolve over generations in a comparable way to DNA. The research, reported Friday in the journal Science, has implications for the fields of molecular medicine and biotechnology, and sheds new light on how molecules first replicated and assembled into life billions of years ago. Living systems owe their existence to the information-carrying molecules DNA and...

In the chemistry of the living world, a pair of nucleic acids–DNA and RNA–reign supreme. As carrier molecules of the genetic code, they provide all organisms with a mechanism for faithfully reproducing themselves as well as generating the myriad proteins vital to living systems. Yet according to John Chaput, a researcher at the Center for Evolutionary Medicine and Informatics, at Arizona State University´s Biodesign Institute®, it may not always have been so. Chaput...

In the rapid and fast-growing world of nanotechnology, researchers are continually on the lookout for new building blocks to push innovation and discovery to scales much smaller than the tiniest speck of dust.In the Biodesign Institute at Arizona State University, researchers are using DNA to make intricate nano-sized objects. Working at this scale holds great potential for advancing medical and electronic applications. DNA, often thought of as the molecule of life, is an ideal building block...


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
