Promise In Duchenne Muscular Dystrophy Shown With Genetic Editing
2013-06-05 08:48:09

Duke University Using a novel genetic 'editing' technique, Duke University biomedical engineers have been able to repair a defect responsible for one of the most common inherited disorders, Duchenne muscular dystrophy, in cell samples from Duchenne patients. Instead of the common gene therapy approach of adding new genetic material to "override" the faulty gene, the Duke scientists have developed a way to change the existing mutated gene responsible for the disorder into a normally...

Developmental genes often take inputs from two independent sources Albert Erives, associate professor in the University of Iowa Department of Biology, and his graduate student, Justin Crocker, currently a postdoctoral researcher at the Howard Hughes Medical Institute (HHMI) Janelia Farm Research Campus, have conducted a study that reveals important and useful insights into how and why developmental genes often take inputs from two independent “morphogen concentration...

Untangling The Branches Of The Tree Of Life
2013-05-15 10:33:57

Vanderbilt University These days, phylogeneticists — experts who painstakingly map the complex branches of the tree of life — suffer from an embarrassment of riches. The genomics revolution has given them mountains of DNA data that they can sift through to reconstruct the evolutionary history that connects all living beings. But the unprecedented quantity has also caused a serious problem: The trees produced by a number of well-supported studies have come to contradictory...

Carnivorous Plant Gets Rid Of Its Junk DNA
2013-05-13 11:22:44

Brett Smith for redOrbit.com — Your Universe Online There are approximately 3 billion base pairs in the human genome, however, only about 2 percent of those are actual genes. The rest is considered ℠junk´ DNA. For years, scientists have puzzled over the question of why so much of the human genome appears to be useless, and a new study on a bizarre wetland plant could be the key to solving the genetic mystery. Utricularia gibba is a carnivorous plant that...

Sacred Lotus Genome May Hold Key To The Secrets Of Aging
2013-05-13 09:50:59

Lawrence LeBlond for redOrbit.com - Your Universe Online A team of international scientists report today that they have sequenced and annotated the genome of the sacred lotus (Nelumbo nucifera), which is thought to have a powerful genetic system. The team, which includes researchers from the US, China, Australia and Japan, have sequenced nearly 90 percent of the plant´s 27,000 genes. The sacred lotus, which is a symbol of spiritual purity and longevity, has the ability to repair...

HZI researchers discover multiple versions of microbial defense genes that lend themselves to being exploited by biotechnology Even bacteria have a kind of “immune system” they use to defend themselves against unwanted intruders — in their case, viruses. Scientists at the Helmholtz Center for Infection Research (HZI) in Braunschweig, Germany, were now able to show that this defense system is much more diverse than previously thought and that it comes in multiple versions....

A study led by Oscar Fernandez-Capetillo has deciphered the components of the machinery that duplicates DNA, the replisome, on which most chemotherapeutic agents currently act The Genomic Instability Group led by researcher Óscar Fernández-Capetillo at the Spanish National Cancer Research Centre (CNIO), has for the first time obtained a panoramic photo of the proteins that take part in human DNA division, a process known as replication. The research article,...

A new level of variation in messenger RNAs exposed Like musicians in an orchestra who have the same musical score but start and finish playing at different intervals, cells with the same genes start and finish transcribing them at different points in the genome. For the first time, researchers at EMBL have described the striking diversity of messenger RNAs (mRNAs) that such start and end variation produces, even from the simple genome of yeast cells. Their findings, published today in...

Researchers at the University of Bonn decode a kind of trigger switch for the conversion of fat cells For a long time, scientists have dreamt of converting undesirable white fat cells into brown fat cells and thus simply have excess pounds melt away. Researchers at the University of Bonn have now gotten a step closer to this goal: They decoded a "toggle switch" in mice which can significantly stimulate fat burning. The results are now being presented in the scientifc journal "Nature...

An international research team including Christian Schlötterer and Alistair McGregor of the Vetmeduni Vienna has discovered a completely new mechanism by which evolution can change the appearance of an organism.  The researchers found that the number of hairs on flies´ legs varies according to the level of activity of a so-called microRNA.  The results, published in the journal Current Biology, shed a completely new light on the molecular mechanisms of evolution....

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...

tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
