DNA is the building block of life, where DNA overall codes for a protein, which then would carry out its function and contribute in some way to the many pathways of life. In many rare instances, a mutation in the base pairing of DNA would lead to whole proteins changing and therefore can cause many … Read more

Introduction 14.7-23.5 million people with autoimmune diseases in the US and is among the top ten leading causes of death (Khan, 2015). Immune responses and systems of human and rodent males and females differ in significant ways after puberty. Men and women can get the same types of age-related autoimmune disease, yet males experience them … Read more

Introduction Energy can be found anywhere in the world, and it stays that way, “it cannot be created or destroyed” from the law of conservation of energy. However, every energy can be converted, for example, a kinetic energy can be converted to an electrical energy and when a dynamite explodes it is the chemical energy … Read more

Abstract We describe the isolation and characteristics of a novel thermophilic bacterium from soil. The organism is a member of the Anoxybacillus genus based on phylogenetic analysis of the 16S rRNA gene. The 16S rRNA of the organism shares >99% sequence identity with those of two species, A. rupiensis and A. geothermalis. We named this … Read more

The American Museum of Natural History has a recent exhibit called, “Meet Your Microbe.” In this exhibit, attendees at the Natural History Museum learn about the microbes contained within the human body. These microbes are not only plentiful but they are also a vital part of the human ecosystem. Not only does this exhibit teach … Read more

Introduction Frisbees, for many years now, have been a source of recreation used commonly by people belonging to all age groups. Frisbees or flying disks are the base for many games such as fricket, disk golf, etc. The disks made of plastic can travel long distances. The history of the flying disk goes back to … Read more

Abstract The major objective of this experiment was to observe if the integration of pGLO, as a plasmid vector, into the genome of Escherichia Coli, would result in bacteria that glows. It was based off of three environmental factors; LB nutrient broth, the antibiotic ampicillin, and arabinose sugar. The transformation vector used included the use … Read more

SEQUENCING Computer scientists are engaged in the analysis of large datasets generated through Next Generation Sequencing approaches.  Much of this type of research will require extensive collaboration with biologists. This course was designed to prepare students for NGS based collaborative research by teaching the vocabulary and a basic understanding of the tools used in molecular … Read more

This study was conducted to evaluate the physiological indices in relation to the screening of cold tolerant rapeseed (Brassica napus L.) genotypes for drought tolerance and study yield and yield components under early and late season water deficit stress. Six rapeseed (Brassica napus L.) genotypes including Karaj 1, Karaj 3, Opera, Okapi, Licord and Modena … Read more

The preservation of bodies has been around for thousands of years. When one thinks back to where everything all started they would most likely think about the Egyptians and the rituals they used back then. As the years go by, human preservation has changed drastically. In this day in age, there are many different methods … Read more

An enzyme assay to determine the rate of succinate dehydrogenase (complex II) activity in Brassica oleracea and the effects of malonate on complex II indirectly using dichlorophenol indophenol Abstract In this study, the rate of succinate dehydrogenase activity in the mitochondria of Brassica oleracea was assessed using an enzyme assay. Isolated mitochondria and mitochondria-free fractions … Read more

Abstract Background: Titanium dioxide nanoparticles are among the most commonly used metal oxide nanoparticles in industrial products, such as cosmetics, sunscreens, food products, paints and drugs. They have been reported to elicit various adverse cellular effects including oxidative stress and deoxyribonuclic acid  (DNA) damage. Aim: To evaluate the beneficial effect of idebenone against the titanium … Read more

One often thinks of bacteria and multicellular organisms as simple but even the most simple bacterium and organism have the most complex task when it comes to gene regulation. Bacteria in your gut or organisms in general carry around thousands of different types of genes. These genes most likely encode proteins, each of which has … Read more
