We found that a strains of Yersinia pestis (KIM5) which lacked the nhaA gene was fully attenuated in a plague model. This gene produces a protein of the sodium-proton antiporter family which expel sodium ions from the bacterial cytoplasm in exchange for hydrogen ions, or protons, from the surrounding environment....
Adequate energy stores are essential for animal survival, and sophisticated neuroendocrine mechanisms evolved to stimulate foraging in response to nutrient deprivation. Food search behavior is usually investigated in young animals, and it is not known how aging alters this behavior. To address this question in Drosophila, we compared the ability...
Some studies have found that responses are faster when the orientation of an object’s graspable part corresponds with the response location than when it does not (i.e., the object-based correspondence effect). We examined Goslin et al.’s (2012) claim that the effect is the result of object-based attention (visual-action binding). As...
Most animals are active either during the day, night, or twilight, and transition periods between these times exhibit interesting behavior. Actions may be related to avoiding predators, seeking shelter, defending territory, feeding, or other interests. Herbivorous fishes on coral reefs, such as parrotfishes, forage constantly throughout daylight periods due to...
Crime rates affect everything from home values, to the quality of education. Through the use of Social Disorganization Theory this paper will support the hypothesis that there is a correlation between neighborhood upkeep and crime rates within neighborhoods. Social Disorganization theory itself aims to show the correlation between the place...

In the US, significant research is ongoing regarding the interactions of pesticides with species and processes within wetland ecosystems. For example, the effect of such pollutants on amphibian survival and physiology has been an area of focused research. Negative impacts of pesticides to non-target organisms (e.g. amphibians) have been observed....
It has been hypothesized that caffeine intake can directly interfere with estrogen synthesis; it is also well documented that caffeine can increase energy expenditure. Active women with ExMD are at risk for the female athlete triad, a syndrome associated with negative energy balance, leading to menstrual dysfunction and eventually poor...
The presence of nitrates and nitrites in food is associated with an increased risk of gastrointestinal cancer and, in infants, methemoglobinemia. Nitrites are produced endogenously through the oxidation of nitric oxide and through a reduction of nitrate by commensal bacteria in the mouth and gastrointestinal tract. Despite the physiologic roles...
Parents play an essential role in their child’s development of the skills needed for self-regulation. The current study examined the relationship between parental marital status and child self-regulation. Analyzing a sample of 328 preschool children, results indicate having married parents is related to higher self-regulation in children. These results suggest...
