women, and children who settled the coast. Turns out, researchers had it incorrect from the very beginning. A team that was led by archaeologist Charles Ewen recently put the ring through a lab test at East Carolina University. They used a x-ray fluorescence device, which reveals an object’s exact elemental composition without destroying ay part of it. Ewen’s reaction was a stunned one when he founded the results. There were high levels of copper with some zinc and traces of silver, lead, tin,…

Nikola Tesla The inventor Nikola Tesla lived from July 10, 1856 to January 7, 1943, he was a well-known engineer who designed the alternating-current (AC) electric system. He was born in what is now Croatia; he came to the United States in 1884 and worked for Thomas Edison for a while before they both went their separate ways. Tesla sold several patent rights to George Westinghouse; one of those was his AC machinery. During Tesla’s career he discovered, designed and developed ideas for a number…

The Shroud of Turin is one of the most analyzed artifacts in the world, consuming well over 100,000 hours of research. It bears the image of a bearded man who was crucified. The wounds shown on the Shroud are similar to the ones that Jesus suffered as described in the four gospels, and many believe that it is the Shroud in which Jesus was wrapped after his crucifixion. The history of the Shroud is uncertain because it did not seem to surface until the 6th century, but because there is no…

Genetic Engineering Imagine a world with no genetic diseases or illnesses, where both humans and animals are born healthy without the possibility of inheriting or contracting a deadly disease. With genetic engineering, this world could become reality. Genetic engineering is the process of modifying the characteristics of an organism by altering its genetic material. Genetic engineering is a touchy subject. Many questions arise when the topic of genetic engineering comes up, many of them…

Abstract This experiment was a study of the different properties of a lipid bilayer. We used fluorescent microscopy to study the lateral diffusion of lipids and binding properties biotin and anti-biotin. The effect cholesterol has on the fluidity of the membrane was tested using Fluorescent Recovery After Photobleaching (FRAP). We used a Nikon Eclipse 50i upright fluorescent microscope with a Digital Sight DM-2MBW CCD camera to take images of the bilayer after photobleaching. Using these images…

Microbiota are microscopic organisms such as viruses, bacteria, archaea, and eukaryotes that influence human health through a commensal interaction. Location of microbiota can be internal or external such as the gut, mouth, placenta, skin, and vagina. These microbes are classified into four major phyla: Firmicutes, Bacteriodetes, Actinobacteria, and Proteobacteria. Microorganisms in the Firmicute phylum are typically Gram positive bacteria, either rod-shaped or spherical and function as obligate…

Introduction: Forensic science is the application of various scientific techniques and methods to investigate the physical Crime evidence. Forensic science links the Suspect, victim to crime scene, and link victim to suspect and suspect to victim. To determine the relevance of the evidence, number of different techniques are being used. This evidence is than presented in court of law in order to determine the innocence or guilt of a suspect. Different type of cases are encountered like rape,…

The first time I learned about structural biology was when I took Comprehensive Biochemistry I during my senior year at University of Maryland, Baltimore County. What was intriguing was how quickly I learned the concepts, and how easy it was for me to see conformational changes in three-dimensional space. I have always been a visual-oriented person, and until senior year of college I found that it was hard to find areas of research in biochemistry that utilize a person’s ability to analyze…

UROLOGY With arrival of Dr. Kittles in 2014 and new Urology Chief, Dr. Lee in 2016, the division of Urology is undergoing a renaissance and expansion of existing programs and the development of new research and academic endeavors. The Division is focusing on a number of new projects such as: Renal Cell Carcinoma, Prostate Cancer, Pelvic Floor and Holmium laser prostatectomy outcomes. At the recent American Urological Association-Western Section meeting in Kauai, Hawaii October…
