Most cancer treatments are blunt. In an attempt to eradicate tumors, oncologists often turn to radiation or chemotherapy, which can damage healthy tissue along with the cancerous growths. New research from C. David Allis' laboratory at Rockefeller University may bring scientists closer to designing cancer therapeutics that can target tumors with pinpoint accuracy. Their findings, published last week in Science Express, follow a recent series of discoveries by several international genome...

redOrbit Staff & Wire Reports - Your Universe Online European researchers have adapted the latest techniques of DNA sequencing to create a novel screening procedure that accurately determines the amount of animal, plant and microbial substances in foods. In pilot studies, the new method was able to successfully detect the presence of a 1 percent content of horsemeat in products, and was able to determine the actual amount with a high degree of precision. The researchers from...

Predictability is often used synonymously with “boring,” as in that story or that outcome was so predictable. For practitioners of synthetic biology seeking to engineer valuable new microbes, however, predictability is the brass ring that must be captured. Researchers with the multi-institutional partnership known as BIOFAB have become the first to grab at least a portion of this ring by unveiling a package of public domain DNA sequences and statistical models that greatly...

Imagine two steel springs identical in look and composition but that perform differently because each was tempered at a different rate. A team of researchers including a Texas A&M University molecular biologist has shown that concept – that the speed of creation affects performance – applies to how a protein they studied impacts an organism's circadian clock function. This discovery provides new insights into the significance of the genetic code for controlling the rates at...

The circadian clocks that control and influence dozens of basic biological processes have an unexpected "snooze button" that helps cells adapt to changes in their environment. A study by Vanderbilt University researchers published online Feb. 17 by the journal Nature provides compelling new evidence that at least some species can alter the way that their biological clocks function by using different "synonyms" that exist in the genetic code. "This provides organisms with a novel and...

Genes relocated from their correct position in the nucleus cause them to malfunction and this may lead to the heart, blood vessels and muscles breaking down.Singapore, Feb 8, 2013 - (ACN Newswire) - Scientists from Singapore and Germany have identified that the proteins lamin A (Lmna) and lamin B receptor (Lbr) are essential for holding silent genes in their correct position at the edge of the nucleus, in the form of heterochromatin(1). A deviation from their normal position will cause the...
