DOE/Joint Genome Institute In the Lewis Carroll classic, Through the Looking Glass, Humpty Dumpty states, "When I use a word, it means just what I choose it to mean—neither more nor less." In turn, Alice (of Wonderland fame) says, "The question is, whether you can make words mean so many different things." All organisms on Earth use a genetic code, which is the language in which the building plans for proteins are specified in their DNA. It has long been assumed that there is only one...

Human genes are preferentially encoded by codons that are less likely to be mistranscribed (or "misread") into a STOP codon. This finding by Brian Cusack and colleagues from the Max Planck Institute for Molecular Genetics in Berlin and the CNRS in Lyon and Paris is published in the open-access journal PLoS Genetics on October 13th, 2011. Since the completion of the human genome sequence over a decade ago, a multitude of studies have investigated the forces that have shaped the genome over...

Salk Institute researchers have built artificially enhanced bacteria capable of producing new kinds of synthetic chemicals A strain of genetically enhanced bacteria developed by researchers at the Salk Institute for Biological Studies may pave the way for new synthetic drugs and new ways of manufacturing medicines and biofuels, according to a paper published September 18 in Nature Chemical Biology. For the first time, the scientists were able to create bacteria capable of effectively...

(Ivanhoe Newswire) "“ New tools have been revealed for rewriting the code of life. Most DNA editing tools are slow, expensive, and hard to use. Now, scientists have developed fast and more efficient genome-scale editing tools. "The payoff doesn't really come from making a copy of something that already exists, you have to change it"”functionally and radically," George Church, a professor of genetics at Harvard Medical School who led the research effort, was quoted saying. From...

Gene mutations on the X chromosome lead to progressive hearing impairment Excessive noise is not the only thing that causes damage to hearing. In many cases, genetic factors are responsible for the loss of hearing at a young age. Researchers at the Max Planck Institute for Molecular Genetics in Berlin together with colleagues from Nijmegen have discovered a previously unknown genetic cause of progressive hearing impairment: the disease is caused by mutations of the SMPX (small muscle...

Ben-Gurion University of the Negev researcher identifies defect in the 21st amino acid that leads to progressive brain atrophy A research team at Ben-Gurion University of the Negev and Soroka University Medical Center in Beer-Sheva, Israel has detected a genetic mutation resulting in a progressive disease of severe mental retardation and epilepsy beginning at infancy. The research was just published in the American Journal of Human Genetics. The team, led by BGU Prof. Ohad Birk of the...
