redOrbit Staff & Wire Reports - Your Universe Online A chemical model developed by a team of US researchers shows how the Earth's first life forms may have packaged the genetic coding material known as ribonucleic acid (RNA), demonstrating one of the earliest steps that could have paved the way for the formation of cellular life some four billion years ago. The Penn State University scientists behind the project used a type of macromolecule called polymers to create primitive...

Innovations in RNA manipulation could lead to advances in many products Researchers at the U.S. Department of Energy's (DOE's) Joint BioEnergy Institute (JBEI) announced today a major breakthrough in engineering systems of RNA molecules through computer-assisted design, which could lead to important improvements across a range of industries, including the development of cheaper advanced biofuels. Scientists will use these new "RNA machines", to adjust genetic expression in the cells of...

Joint BioEnergy Institute researchers develop CAD-Type tools for engineering RNA control systems The computer assisted design (CAD) tools that made it possible to fabricate integrated circuits with millions of transistors may soon be coming to the biological sciences. Researchers at the U.S. Department of Energy (DOE)'s Joint BioEnergy Institute (JBEI) have developed CAD-type models and simulations for RNA molecules that make it possible to engineer biological components or "RNA devices"...

Discovery opens a new targeting scheme for drug delivery that potentially would reduce toxic side effects An anti-cancer drug used extensively in chemotherapy binds pervasively to RNA -- up to 20-fold more than it does to DNA, a surprise finding that suggests new targeting approaches might be useful, according to University of Oregon researchers. Medical researchers have long known that cisplatin, a platinum compound used to fight tumors in nearly 70 percent of all human cancers,...

Scientists are reporting an advance in overcoming a major barrier to the use of the genetic material RNA in nanotechnology "” the field that involves building machines thousands of times smaller than the width of a human hair and now is dominated by its cousin, DNA. Their findings, which could speed the use of RNA nanotechnology for treating disease, appear in the monthly journal ACS Nano. Peixuan Guo and colleagues point out that DNA, the double-stranded genetic blueprint of life, and...

Crystal structure shows how RNA, one of biology's oldest catalysts, is made In today's world of sophisticated organisms proteins are the stars. They are the indispensible catalytic workhorses, carrying out the processes essential to life. But long, long ago ribonucleic acid (RNA) reigned supreme. Now Northwestern University researchers have produced an atomic picture that shows how two of these very old molecules interact with each other. It is a rare glimpse of the transition from an...

Within a dangerous stomach bacterium, Yale University researchers have discovered an ancient but functioning genetic remnant from a time before DNA existed, they report in the August 13 issue of the journal Science. To the surprise of researchers, this RNA complex seems to play a critical role in the ability of the organism to infect human cells, a job carried out almost exclusively by proteins produced from DNA's instruction manual. "What these cells are doing is using ancient RNA technology...

An extremely small RNA molecule created by a University of Colorado at Boulder team can catalyze a key reaction needed to synthesize proteins, the building blocks of life. The findings could be a substantial step toward understanding "the very origin of Earthly life," the lead researcher contends. The smallest RNA enzyme ever known to perform a cellular chemical reaction is described in a paper published this week in the Proceedings of the National Academy of Sciences. The paper was written...

The study was carried out by 3 European researchers, 1 from Universitat Autònoma de Barcelona A research published in Proceedings of National Academy of Sciences rejects the theory that the origin of life stems from a system of self-catalytic molecules capable of experiencing Darwinian evolution without the need of RNA or DNA and their replication. The research, which was carried out with the participation of Mauro Santos, researcher of the Department of Genetics and...
