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...

To Test 'Histone Code' Researchers Exploit Gene Position
2013-01-03 13:25:12

University of California - San Diego In a novel use of gene knockout technology, researchers at the University of California, San Diego School of Medicine tested the same gene inserted into 90 different locations in a yeast chromosome — and discovered that while the inserted gene never altered its surrounding chromatin landscape, differences in that immediate landscape measurably affected gene activity. The findings, published online in the Jan. 3 issue of Cell Reports,...

Bat DNA Analysis Provides Key Evolutionary Insights
2012-12-21 14:56:48

Brett Smith for redOrbit.com - Your Universe Online A comparative genetic analysis of two distantly related bat species has revealed new insights into the evolutionary development of flight and disease resistance, according to a new report in the latest edition of the journal Science. As the only mammals capable of sustained flight, bats are an anomaly in the animal world. They also have a predilection for transmitting diseases that do not appear to affect the animals themselves....

Autism And Other Disorders May Be Caused By Genetic Hotspot Mutations
2012-12-21 06:47:01

[ Watch the Video: Mutation Hotspots in Autism Genes ] Connie K. Ho for redOrbit.com — Your Universe Online A group of international researchers led by a team of investigators from the School of Medicine at the University of California, San Diego (UCSD), recently revealed a new study that provides signals as to the causes of autism and other related disorders. With the findings, it is possible that there are elevated mutation rates in specific parts of the genome that adds to...

How does evolution innovate? We exist because our ancestors have had the ability to adapt successfully to changes in their environment; however, merely examining present-day organisms can limit our understanding of the actual evolutionary processes because the crucial events have been masked by the passage of aeons — what we need is a time machine. Scientists from VIB, KU Leuven, University of Ghent and Harvard have done the next-best thing; by reconstructing DNA and proteins from...

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...

toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
