Ewing Sarcoma by Mafalda von Alvensleben Ewing Sarcoma, though unbeknownst to most of the general population, is a type of pediatric cancer that affects the soft tissue or bone. Approximately 225 people in the United States are diagnosed with this disease each year, primarily those between the ages of ten and twenty, making it comprise about 1% of all pediatric cancers. Ewing Sarcoma is typically discovered via radio-imaging techniques and confirmed by a biopsy of the […]

Rate of Allogrooming Vigilance in Ant Species as it Relates to Exoskeleton Morphology

Michael Taffe*, Susan Goethals, Clint Penick, Ph.D., Adrian Smith, Ph.D. *Corresponding Author: michaeltaffe3@gmail.com Cardinal Gibbons High School, 1401 Edwards Mill Rd. Raleigh, NC 27603 Abstract: Although extensive research has been performed on allogrooming behavior in mammals and birds, very little has been done on the allogrooming behaviors of insects. Ant allogrooming behavior is believed to contribute to the overall health of the colony due to their use of phenylacetic acid in grooming activities. This study […]

Examining the Efficacy of Hydrosols of Medicinal Plants Endemic to Guam Against Staphylococcus aureus

St. John’s School Guam Alice Yi Abstract Staphylococcus aureus (S. aureus) is a bacterium that is commonly found on our epidermis. However, when one has an open wound, S. aureus can enter the wounds and cause severe infections. Unfortunately, certain strains of S. aureus has become resistant to penicillin, the antibiotic commonly used to treat S. aureus infections. As antibiotic-resistant bacteria increases, scientists have studied the effects of medicinal plant extracts against S. aureus, as […]

Lactose Assay using Spectrophotometry to detect and analyze Competitive Inhibition from ONPG

By: Melissa Manetsch and Maggie Shutts Abstract: The purpose of this research is to determine if it is possible to develop a qualitative assay to assess whether a sample containing an unknown concentration of lactose is below or above the threshold of an individual’s tolerance. Our research would then be able to determine if it is valid to create an assay in which quantifying the effects of varying concentrations of lactose on ONPG due to […]
