<em>Aedes aegypti</em> Embryo (IMAGE) University at Buffalo Caption A microscope image shows a four-segment section of the nervous system of an Aedes aegypti mosquito embryo. The dark purple indicates areas where a gene called "short gastrulation" is being expressed. Using a software tool called SCRMshaw, researchers were able to identify the DNA sequences that regulate this mosquito gene, as well as the sequences regulating its counterpart in the fruit fly.
