Numerous viruses are used in the service of science today. They serve as gene taxis to transfer therapeutic genes into body cells or as therapeutic viruses targeted to infect and destroy cancer cells. For such applications, the viruses are often equipped with additional genes, such as for immune mediators or for proteins inducing programmed cell death. However, these gene products can harm the body if they are released at the wrong moment or at excessive levels. "Ideally, we want to be able...

Harvard Scientists Write Book In DNA And Accurately Copy, Read It Back
2012-08-17 10:57:16

Lawrence LeBlond for redOrbit.com - Your Universe Online DNA, the building block of life, is now home to more than just the world´s living creatures. Scientists from Harvard University report that they have written an entire novel in DNA, a feat that could revolutionize our ability to save data. Our genetic code packs billions of gigabytes into a single gram. That is significantly more information that a single microchip could even think about storing. In fact, a single milligram...

Possible Tool To Study Aging From “Selfish” DNA In Animal Mitochondria
2012-08-10 09:14:10

Researchers at Oregon State University have discovered, for the first time in any animal species, a type of “selfish” mitochondrial DNA that is actually hurting the organism and lessening its chance to survive — and bears a strong similarity to some damage done to human cells as they age. The findings, just published in the journal PLoS One, are a biological oddity previously unknown in animals. But they may also provide an important new tool to study human aging,...

100 gene deletions in mice identifies 9 new genes that determine bone strength A genetic screening approach to studying bone disease has found nine new genes associated with bone health and suggests a new way to discover genes that may be implicated in human skeletal diseases. A collaborative study of the mineral content, strength and flexibility of bones has found clues to the cause of bone disorders such as osteoporosis, osteogenesis imperfecta, and high bone density syndromes. The...

Library of Genetic Circuits Developed For Scientific Functions
2012-08-03 13:24:55

April Flowers for redOrbit.com - Your Universe Online For about a dozen years, synthetic biologists have been working on designing genetic circuits to perform novel functions such as manufacturing new drugs, producing fuel or even programming the suicide of cancer cells. Many factors have to be controlled for this dream to become a reality. Scientists have to gain control over complex genetic and cellular components, including genes and the regulatory proteins, called transcription...

Footprint Of A Fly Virus Found In Fly DNA

The discovery of virus-like genes in the DNA of a commonly studied fruit fly could enable research on whether animals hijack viral genes as an anti-viral defense In a curious evolutionary twist, several species of a commonly studied fruit fly appear to have incorporated genetic material from a virus into their genomes, according to new research by University at Buffalo biologists. The study found that several types of fruit fly -- scientific name Drosophila -- harbored genes similar to...

A new technique will allow plant breeders to introduce valuable crop traits even without access to the full genome sequence of that crop. The technique, published in the journal Nature Biotechnology, links important agronomic traits in crop plants with active regions of the genome. Instead of requiring knowledge of the crop's complete genome, it identifies only expressed genes. "For many crop plants, markers are still lacking because of the complexity of some plants' genomes and the...

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...

call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
