(University of Alberta) People are different, both physically and mentally, but genetically everyone is very similar. That's been the thought of scientists for decades now. But with population research becoming more and more common, the University of Alberta's Tim Caulfield is concerned that genetic research could awaken racist attitudes.

| • | Isolation, Characterization and Growth Response of Pesticides Degrading Bacteria |
| In Pakistan, insecticides are widely used in agriculture. Despite their biodegradable nature, some are highly toxic and their residues are found in the environment. Moreover, its removal from wastewater generated during manufacture becomes inevitable. Reports on the mineralization of a spectrum of different insecticides by a single potential strain are scarce. In this study, a bacterial strain was isolated from soil using enrichment technique and identified as Pseudomonas sp. by microscopic examination and biochemical tests. Growth curve experiments showed that Pseudomonas strain was able to grow in nutrient medium containing malathion (35-220 mg L-1), methamidophos (80-320 mg L-1), cartap (60-120 mg L-1) and cypermethrin (40-125 mg L-1) pesticide. However, the optimum concentration which support normal bacterial growth during 24 h was found to be 120 mg L-1 malathion, 160 mg L-1 methamidophos, 80 mg L-1 cartap and 60 mg L-1cypermethrin. When compared with the control test, a significant increased in bacterial population was noted at low concentration of each pesticide, however at high concentration lag phase increased but no zone of inhibition observed. These data indicate that the isolated Pseudomonas strain can be used as a microorganism for the bioremediation of pesticide contaminated soil or water. | |

| • | Feature context-dependency and complexity-reduction in probability landscapes for integrative genomics |
| Background: The question of how to integrate heterogeneous sources of biological information into a coherent framework that allows the gene regulatory code in eukaryotes to be systematically investigated is one of the major challenges faced by systems biology. Probability landscapes, which include as reference set the probabilistic representation of the genomic sequence, have been proposed as a possible approach to the systematic discovery and analysis of correlations amongst initially heterogeneous and un-relatable descriptions and genome-wide measurements. Much of the available experimental sequence and genome activity information is de facto, but not necessarily obviously, context dependent. Furthermore, the context dependency of the relevant information is itself dependent on the biological question addressed. It is hence necessary to develop a systematic way of discovering the context-dependency of functional genomics information in a flexible, question-dependent manner. Results: We demonstrate here how feature context-dependency can be systematically investigated using probability landscapes. Furthermore, we show how different feature probability profiles can be conditionally collapsed to reduce the computational and formal, mathematical complexity of probability landscapes. Interestingly, the possibility of complexity reduction can be linked directly to the analysis of context-dependency. Conclusion: These two advances in our understanding of the properties of probability landscapes not only simplify subsequent cross-correlation analysis in hypothesis-driven model building and testing, but also provide additional insights into the biological gene regulatory problems studied. Furthermore, insights into the nature of individual features and a classification of features according to their minimal context-dependency are achieved. The formal structure proposed contributes to a concrete and tangible basis for attempting to formulate novel mathematical structures for describing gene regulation in eukaryotes on a genome-wide scale. | |
