Pioneering new research from a team of Indiana University Bloomington biologists has shown for the first time that a protein which has been long known to be critical for the initiation of protein synthesis in all organisms can also play a role in the regulation of gene expression in some bacteria, and probably land plants as well. The protein, called translation initiation factor 3, or IF3, is one of three proteins that make up the core structure of the machinery needed to guide the...

University of Adelaide researchers have identified a likely molecular pathway that causes a group of untreatable neurodegenerative diseases, including Huntington's disease and Lou Gehrig's disease. The group of about 20 diseases, which show overlapping symptoms that typically include nerve cell death, share a similar genetic mutation mechanism ‒ but how this form of mutation causes these diseases has remained a mystery. "Despite the genes for some of these diseases having been...

Getting the message about bitter taste Do you love chomping on raw broccoli while your best friend can't stand the healthy veggie in any form or guise? Part of the reason may be your genes, particularly your bitter taste genes. Over the past decade, scientists at the Monell Center and elsewhere have made headway in understanding how variants of bitter taste receptor genes can help account for how people differ with regard to taste perception and food choice. However, some perplexing...

Next Generation Sequencing Reveals Absence Of DNA In Sub-fossilized Insects

University of Manchester Research just published in the journal PLOS ONE by a team of researchers from the Faculty of Life Sciences at The University of Manchester can now confirm that the existence of DNA in amber fossils is highly unlikely It is hardly possible to talk about fossil insects in amber without the 1993 movie Jurassic Park entering the debate. The idea of recreating dinosaurs by extracting DNA from insects in amber has held the fascination of the public for two decades....

Near-optimal Genetic Code Model Created By Researchers
2013-08-29 04:15:01

redOrbit Staff & Wire Reports - Your Universe Online By creating a model of genetic code evolution, researchers have discovered new information about how RNA signaling could have developed into the “near-optimal” modern genetic code. Lead author Justin Jee, a doctoral student at NYU School of Medicine, and colleagues set out to account for the composition of the genetic code, which makes it possible for proteins to be constructed from amino acids with high specificity based on...

Discovery of long non-coding RNA's role in neurogenesis may lead to cures for diseases such as Alzheimer's diseaseSingapore, Aug 28, 2013 - (ACN Newswire) - Scientists at A*STAR's Genome Institute of Singapore (GIS) have discovered an unusual gene that controls the generation of neurons[1]. This important finding, which is crucial in understanding serious diseases of the brain such as Alzheimer's disease, was reported in the 8th August 2013 issue of the prestigious...

In an era of widespread genetic sequencing, the ability to edit and alter an organism's DNA is a powerful way to explore the information within and how it guides biological function. A paper from the University of Wisconsin–Madison in the August issue of the journal GENETICS takes genome editing to a new level in fruit flies, demonstrating a remarkable level of fine control and, importantly, the transmission of those engineered genetic changes across generations. Both features are key...

The essence of male beauty is down to the way males use their genes rather than what genes they have, according to a new study into the sexual attractiveness of turkeys. Geneticists have long puzzled over why individuals of the same sex show a greater or lesser degree of sexual attractiveness. In other words - why are some people better looking than others when they're genetically similar? In a new study, published today in the journal PLoS Genetics, scientists turned to male wild...

How Genes Tell Cellular Construction Crews, 'Read Me Now!'

Stowers Institute for Medical Research Stowers researchers show that DNA sequences at the beginning of genes -- at least in fruit flies -- contain more information than previously thought When egg and sperm combine, the new embryo bustles with activity. Its cells multiply so rapidly they largely ignore their DNA, other than to copy it and to read just a few essential genes. The embryonic cells mainly rely on molecular instructions placed in the egg by its mother in the form of RNA....

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...

out-herod
  • In the phrase to out-herod Herod, to be more violent than Herod (as represented in the old mystery plays); hence, to exceed in any excess of evil.
Herod refers to 'Herod the Great,' a Roman client king and 'a madman who murdered his own family and a great many rabbis.' According to the OED, the term is 'chiefly with allusion to Shakespeare's use' in Hamlet.
