| New discovery could change the face of cell-biology research Posted: 11 Oct 2011 02:15 PM PDT Rewrite the textbooks and revisit old experiments, because there's a new cog in our cellular machinery that has been just been discovered.  |
| Crop improvement and human medicine: Using proteins to target and manipulate specific genes Posted: 11 Oct 2011 11:57 AM PDT Scientists are using certain proteins to target and manipulate specific genes. That could lead to breakthroughs in understanding gene function and improving traits in livestock and plants, and even treating human genetic disorders.  |
| Mushroom compound appears to improve effectiveness of cancer drugs, study suggests Posted: 11 Oct 2011 10:20 AM PDT A compound isolated from a wild, poisonous mushroom growing in a southwest China forest appears to help a cancer killing drug fulfill its promise, researchers report.  |
| Uncharted territory: Scientists sequence the first carbohydrate biopolymer Posted: 11 Oct 2011 08:27 AM PDT For the first time ever, a team of researchers has announced the sequence of a complete complex carbohydrate biopolymer. The surprising discovery provides the scientific and medical communities with an important and fundamental new view of these vital biomolecules, which play a role in everything from cell structure and development to disease pathology and blood clotting.  |
| Improved method for detecting mutant DNAs Posted: 11 Oct 2011 08:23 AM PDT Molecular DNA testing methods offer clinicians powerful tools that serve to confirm or identify disease diagnoses. High sensitivity and high specificity, however, are frequently a challenge to achieve with these methods. Researchers now describe a new, robust technique that holds promise for identifying trace mutant DNA sequences (signals) in an overwhelming population of unmutated DNA (noise).  |
| New 'genome mining' technique streamlines discovery from nature Posted: 11 Oct 2011 07:21 AM PDT A newly developed method for microscopically extracting, or "mining," information from genomes could represent a significant boost in the search for new therapeutic drugs and improve science's understanding of basic functions such as how cells communicate with one another.  |
| Adjusting to high temperatures: Researchers discover multifunctional enzyme active in metabolism Posted: 11 Oct 2011 04:48 AM PDT Gluconeogenesis is the ability to re-synthesize sugar out of simpler chemical building blocks. It is a central pathway of the metabolism in humans as well as simple bacteria. Researchers have been unable to scientifically analyze this conclusively until now. Scientists in Germany have described a fundamentally new type of multifunctional enzyme in this metabolic pathway.  |
