U-M researchers develop method that could enhance gene sequencing data When researchers sequence the RNA of cancer cells, they can compare it to normal cells and see where there is more RNA. That can help lead them to the gene or protein that might be triggering the cancer. But other than spotting a few known instigators, what does it mean? Is there more RNA because it´s synthesizing too quickly or because it´s not degrading fast enough? What part of the biological equilibrium...

DNA Data Storage Moves One Step Closer
2013-01-24 04:54:46

April Flowers for redOrbit.com - Your Universe Online Scientists from Cambridge University have developed a new method of long-term information storage: synthesized DNA. "We´re using DNA here as a chemical molecule of storage. It just happens to be the same molecule that is used in our bodies as well," Ewan Birney, senior author of the study and geneticist at the United Kingdom's European Bioinformatics Institute told CNN. DNA that is kept cold, dry and dark will last for a very...

A new metabolic engineering tool that allows fine control of gene expression level by employing synthetic small regulatory RNAs was developed to efficiently construct microbial cell factories producing desired chemicals and materials Biotechnologists have been working hard to address the climate change and limited fossil resource issues through the development of sustainable processes for the production of chemicals, fuels and materials from renewable non-food biomass. One promising...

Human Genome Found To Contain Quadruple Helix DNA Strands
2013-01-21 05:09:41

redOrbit Staff & Wire Reports - Your Universe Online On the 60th anniversary of the publication of the paper describing the double-helix structure of DNA, researchers from Cambridge University reportedly have proven the existence of four-stranded “quadruple helix” DNA structures within the human genome. It was in 1953 that James D. Watson and Francis Crick, also of Cambridge University, published a paper which described the interweaving structure of the double-stranded...

Genes Found That Tell Mice How To Build Their Burrows
2013-01-18 12:33:47

Brett Smith for redOrbit.com - Your Universe Online By studying oldfield mice — colloquially known as ℠beach mice´ (Peromyscus polionotus) — as they dug through a mound of dirt in her San Diego garage, biologist Hopi Hoekstra discovered that the diligent rodents construct their burrows in extremely predictable patterns. Working on a hunch that the mice probably inherit this behavior, she and a team of colleagues conducted a genetic analysis of the tiny rodents...

When Charles Darwin first sketched how species evolved by natural selection, he drew what looked like a tree. The diagram started at a central point with a common ancestor, then the lines spread apart as organisms evolved and separated into distinct species. In the 175 years since, scientists have come to agree that Darwin´s original drawing is a bit simplistic, given that multiple species mix and interbreed in ways he didn´t consider possible (though you can´t fault the guy...

Shining Light On Important Role Performed By Dark Matter Within Each Of Our Genes
2013-01-07 09:28:56

University of North Carolina Health Care Research findings from the University of North Carolina School of Medicine are shining a light on an important regulatory role performed by the so-called dark matter, or "junk DNA," within each of our genes. The new study reveals snippets of information contained in dark matter that can alter the way a gene is assembled. "These small sequences of genetic information tell the gene how to splice, either by enhancing the splicing process or...

Little Brown Bats Found To Have A Rare Active Jumping Gene
2013-01-04 07:37:34

April Flowers for redOrbit.com - Your Universe Online Jumping genes, or transposable elements, are strange rogue sequences from which most of our DNA can be traced, but are largely idle in mammals. Johns Hopkins researchers report, however, that they have identified a new DNA sequence moving around in bats. This is the first member of the transposable elements class found to be active in mammals. The findings of this study, published online at the Proceedings of the National Academy of...

Knockout Mouse
2013-10-02 11:52:01

A Knockout Mouse is a genetically engineered mouse in which researchers have inactivated, or “knocked out,” an existing gene by replacing it or disrupting it with an artificial piece of DNA. The loss of gene activity frequently causes changes in a mouse’s phenotype, which includes appearance, behavior, or other apparent and biochemical characteristics. Knockout mice are significant animal models for studying the role of genes which have been sequenced but whose functions haven’t...

barghest
  • A goblin in English folklore, often appearing in the shape of a large dog and believed to portend imminent death or misfortune.
  • A ghost, wraith, hobgoblin, elf, or spirit.
The origin of 'barghest' is not known, but it may be from perhaps burh-ghest, town-ghost, or German Berg-geist (mountain spirit) or Bär-geist (bear-spirit).
