Evolution Follows A Predictable Genetic Pattern Researchers Find
2012-10-26 10:20:03

Evolution, often perceived as a series of random changes, might in fact be driven by a simple and repeated genetic solution to an environmental pressure that a broad range of species happen to share, according to new research. Princeton University research published in the journal Science suggests that knowledge of a species' genes – and how certain external conditions affect the proteins encoded by those genes – could be used to determine a predictable evolutionary pattern...

Genetics researchers at the University of Adelaide have solved a 40-year mystery for a family beset by a rare intellectual disability — and they've discovered something new about the causes of intellectual disability in the process. While many intellectual disabilities are caused directly by a genetic mutation in the so-called "protein coding" part of our genes, the researchers found that in their case the answer laid outside the gene and in the regulation of proteins. Protein...

Flycatchers' Genomes Reveal How 1 Species Became 2
2012-10-25 09:07:53

Just how new species are established is still one of the most central questions in biology. In an article in the leading scientific journal Nature, researchers at Uppsala University in Sweden describe how they mapped the genomes of the European pied flycatcher and the collared flycatcher and found that it is disparate chromosome structures rather than separate adaptations in individual genes that underlies the separation of the species. "We were surprised that such a large part of the...

A study led by The University of Manchester has demonstrated that new technology that can analyze millions of gene sequences in a matter of seconds is an effective way to quickly and accurately identify diseases in skeletons. Professor Terry Brown, working in partnership with Professor Charlotte Roberts from Durham University, used a next generation sequencing approach, including hybridization capture technology, to identify tuberculosis genes in a 19th century female skeleton found in a...

Like job-seekers searching for a new position, living things sometimes have to pick up a new skill if they are going to succeed. Researchers from the University of California, Davis, and Uppsala University, Sweden, have shown for the first time how living organisms do this. The observation, published Oct. 19 in the journal Science, closes an important gap in the theory of natural selection. Scientists have long wondered how living things evolve new functions from a limited set of genes....

RNA-world Hypothesis Under The Microscope
2012-10-15 05:27:46

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...

New Concept Dramatically Alters Theory Of Animal Evolution
2012-10-13 08:10:50

April Flowers for redOrbit.com - Your Universe Online New work by Dr. Stuart A. Newman, professor of cell biology and anatomy at New York Medical College, develops a concept that dramatically alters one of the basic assumptions of the theory of evolution. The assumption is that survival is based on a change's functional advantage if it is to persist. Newman, whose life's work has supported the theory of evolution, offers an alternative model where he proposes that the origination of...

Findings question earlier studies and shed light on fundamental cellular process Scientists at the Gladstone Institutes have mapped the precise frequency by which genes get turned on across the human genome, providing new insight into the most fundamental of cellular processes–and revealing new clues as to what happens when this process goes awry. In a study being published this week online in the Proceedings of the National Academy of Sciences, Gladstone Investigator Leor...

Ingenuity iReport for Isoform-level Human RNA-Seq data enables researchers to quickly and easily identify significantly regulated isoforms, interpreting the impact of those expression changes in the context of the pathways,...

Genetics of Intelligence Remains A Riddle
2012-10-03 12:28:03

April Flowers for redOrbit.com - Your Universe Online Your intelligence — like almost all other traits — is a gift from your parents, at least in part. Scientists have known for a long time that intelligence is at least partially inherited through genetics. According to psychological scientist Christopher Chabris, however, it may be some time before researchers can identify the specific genetic roots of intelligence. A new study from Union College shows that the genes long...

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...
