April Flowers for redOrbit.com - Your Universe Online Before DNA became the Earth's primary genetic material over 3.5 million years ago, scientists believe forms of life used RNA to encode genetic instructions. What came before RNA, though? A research team from Weber State University and the Stockholm University think the answer might be N-(2-aminoethyl)glycine AEG, a small molecule that when linked forms a hypothetical backbone for peptide nucleic acids. Scientists hypothesize that...

A team of Scripps Research scientists has created a new analog to DNA that assembles and disassembles itself without the need for enzymes. Because the new system comprises components that might reasonably be expected in a primordial world, the new chemical system could answer questions about how life could emerge.The work, reported in the June 11, 2009 issue of Science Express, an advance, online publication of the journal Science, might also be a starting point on the way to exotic new...

WOBURN, Mass., Oct. 22 /PRNewswire/ -- AdvanDx today announced that a new medical study demonstrated use of AdvanDx's PNA FISH(TM) test reduced mortality by 42% for patients with highly drug resistant Hospital-Acquired Enterococcus faecium bloodstream infections (BSI's). In addition, the study demonstrated that PNA FISH reduced the time to reporting of laboratory identification results for all enterococcal BSI's by 2.6 days and reduced time to appropriate antimicrobial therapy for E....

PITTSBURGH--For the first time, a team of investigators at Carnegie Mellon University has shown that the binding of metal ions can mediate the formation of peptide nucleic acid (PNA) duplexes from single strands of PNA that are only partly complementary. This result opens new opportunities to create functional, three-dimensional nanosize structures such as molecular-scale electronic circuits, which could reduce by thousands of times the size of today's common electronic devices. The research...
