Ability to tune gene activity will permit refined research for drug resistance, cancer Scientists who built a synthetic gene circuit that allowed for the precise tuning of a gene's expression in yeast have now refined this new research tool to work in human cells, according to research published online in Nature Communications. "Using this circuit, you can turn a gene from completely off to completely on and anywhere between those two extremes in each cell at once. It's a nice tool if...

Biologists use technology to observe individual differences in fruit flies To track what they can't see, pilots look to the green glow of the radar screen. Now biologists monitoring gene expression, individual variation, and disease have a glowing green indicator of their own: Brown University biologists have developed a "radar" for tracking ADAR, a crucial enzyme for editing RNA in the nervous system. The advance gives scientists a way to view when and where ADAR is active in a living...

U.S. Department of Agriculture (USDA) scientists have developed a new tool for improving the expression of desirable genes in rice in parts of the plant where the results will do the most good.Roger Thilmony, a geneticist with USDA's Agricultural Research Service (ARS), has shown that the LP2 gene promoter can be used to direct other introduced genes to express beneficial traits in specific plant tissues without the potential for causing unintended consequences. Thilmony works at the ARS Crop...

The goal of tissue engineering is to recapitulate healthy human organs and tissue structures in culture, and then transplant them into patients, where they are fully integrated. This is a complicated process, and the use of high-throughput imaging systems that allow researchers to directly monitor transplanted tissues in live animals over time is important for improving the culturing and implantation techniques, as well as the design of artificial tissue scaffolds. By using transgenic animals...

Live cell imaging techniques are driving a revolution in biological research. Instead of viewing dead tissues and cells fixed at a particular stage of activity, scientists can now visualize dynamic changes as they happen, permitting a better understanding of biological processes. The revolution has been fueled by the implementation of genetically encoded fluorescent proteins, the subject of the 2008 Nobel Prize in Chemistry...

With the implementation of cloning techniques, a team of scientists in South Korea have engineered four beagles that allegedly glow in reddish hues.  The same techniques, they propose, could aid in the development of cures for human diseases.  Though they glow red in the presence of ultraviolet light, the dogs' nails and abdomens appear red even to the naked eye because of their thin skins.  Lee Byeong-chun, a professor at Seoul National University and head of the research...

By MALCOLM RITTER By Malcolm Ritter The Associated Press NEW YORK Three U.S.-based scientists won a Nobel Prize on Wednesday for turning a glowing green protein from jellyfish into a revolutionary way to watch the tiniest details of life within cells and living creatures. Osamu Shimomura, a Japanese citizen who works in the United States, and Americans Martin Chalfie and Roger Tsien shared the chemistry prize for discovering and developing green fluorescent protein, or GFP. When...


Word of the Day
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.
