 | Cytochrome c is a highly conserved protein that is found in many multicellular and unicellular organisms. Cytochrome c is a critical intermediate in apoptosis: a controlled form of cell death that kills cells as part of their natural process of development and in response to environmental condition. To detect whether cytochrome c of the mosquito Aedes aegypti (L.) (AeaCytC) is developmentally regulated, we used quantitative real-time polymerase chain reaction (PCR) ... |

| The Plantenna project has the overlying goal to simply use a plant as an antenna. To do this, special plants called metal hyper accumulators are being tested to observe any antenna like properties. The testing so far has been focused at finding an appropriate testing procedure while analyzing the basic impedance properties of plants concerning the relationships between impedance and test frequency and impedance and plant length. This report will ... |

|
| Silk fibers formed by insects and spiders are noted for their remarkable mechanical properties as well as their durability and biocompatibility. The exceptional solubility in vivo (20-30% w/v) of these proteins is dictated by both the need to produce solid fibers with a high packing fraction and the high mesogen concentration required for lyotropic liquid crystalline spinning, while also achieving high end mechanical properties for survival (orb webs, cocoons). Combining ... |

| Genetic inhibition of two genes, an orphan GPCR and a kinase, have been shown to produce changes in the behavior of mice that suggest the ability to promote sleep and to promote extended wakefulness. One of these is a well-known clock gene, but its effects on normal sleep-wake states had not been characterized. Pharmaceutical investigation of either of these genes appears to be very limited, but could be fruitful in ... |

| Filth flies serve as vectors for many diseases that pose a serious threat to the safety and well-being of deployed military personnel. Our research project targeted the development of new insecticides for fly control. During the 3-year research project, research on control of mosquitoes and flies developed from the initial screening of insecticidal active ingredients to a field testing of new formulation and new application devices. We obtained several insecticides ... |
