Duke researchers have devised a way to quickly and easily target and tinker with any gene in the human genome. The new tool, which builds on an RNA-guided enzyme they borrowed from bacteria, is being made freely available to researchers who may now apply it to the next round of genome discovery. The new method also has obvious utility for gene therapy and for efforts to reprogram stem or adult cells into other cell types – for example, to make new neurons from skin cells....

Students who had their genome tested as part of a groundbreaking medical school course on personalized medicine improved their knowledge of the class materials by an average of 31 percent compared with those who didn't undergo the testing, according to a study by researchers at the Stanford University School of Medicine. While the sample size was small — 23 students sent their saliva to a commercial genetics testing company; eight did not — the results...

Painstaking new analysis of the genetic sequence of the X chromosome—long perceived as the "female" counterpart to the male-associated Y chromosome—reveals that large portions of the X have evolved to play a specialized role in sperm production. This surprising finding, reported by Whitehead Institute scientists in a paper published online this week in the journal Nature Genetics, is paired with another unexpected outcome: despite its reputation as the...

RNA Stores More Functional Genome Data Than Previously Thought

redOrbit Staff & Wire Reports - Your Universe Online Contrary to the belief that a large percentage of the human genome contains "junk" material, a team of Australian scientists report they have discovered an unexpectedly high proportion of functional elements that have been conserved through evolution. According to Dr. Martin Smith and Professor John Mattick of the Garvan Institute of Medical Research in Sydney, less than 1.5 percent of the human genome is devoted to conventional...

Researchers from Boston University School of Medicine (BUSM) and George Washington University (GWU) have developed a method to rapidly identify pathogenic species and strains causing illnesses, such as pneumonia, that could help lead to earlier detection of disease outbreaks and pinpoint effective treatments more quickly. The findings are featured online in the journal Genome Research. Emerging sequencing technologies have revolutionized the collection of genomic data for bioforensics,...

Junk DNA Vital Biological Role
2013-06-27 08:25:25

Rebekah Eliason for redOrbit.com - Your Universe Online At the center of most human cells, genomic DNA lies tucked away within a nucleus. However, a surprisingly small percentage of this DNA actually codes for genes that can be translated into proteins. In fact, some researchers estimate as much as 98 percent of this DNA seems to have a puzzling lack of purpose, leading many to refer to it as 'junk DNA.' However, a new study from UC San Francisco now emphasizes the potentially important...

Because of their central importance to biology, proteins have been the focus of intense research, particularly the manner in which they are produced from genetically coded templates–a process commonly known as translation. While the general mechanism of translation has been understood for some time, protein synthesis can initiate by more than one mechanism. One of the least well understood mechanisms is known as cap-independent translation. Now, John Chaput and his colleagues at...


Word of the Day
ween
  • To think; to imagine; to fancy.
  • To be of opinion; have the notion; think; imagine; suppose.
The word 'ween' comes from Middle English wene, from Old English wēn, wēna ("hope, weening, expectation"), from Proto-Germanic *wēniz, *wēnōn (“hope, expectation”), from Proto-Indo-European *wen- (“to strive, love, want, reach, win”).
