The Subject of Carrots, Eggs, and Waistcoats

The European rabbit or Oryctolagus cuniculus is a mammal that has been spread across the globe. They can be found wild on every continent except Antarctica, where they can only be found domesticated with humans. A group of rabbits is called a fluffle. In the media, rabbits are popular creatures. They are known for their ability to multiply in a short amount of time. They are connected with colorful eggs full of candy or money around Easter time. They wear waistcoats and worry about the time of their pocket watch. They comically evade hunters while munching on only carrots. In reality, rabbits have nothing to do with laying eggs, teatime, or Elmer Fudd. In fact, carrots are not the best for rabbits due to the large sugar content and the possibility of addiction. Rabbits are seen as cuddly, quiet, numerous, and simple. But rabbits are anything but simple. They create complex tunnels and social groups that connect and protect wild rabbits. To show they are happy, rabbits fling themselves into the air. As the third most popular pet, domesticated rabbits are about as common as dogs or cats. It is important to understand the origins of domestic and wild rabbits and the significant role they play in the global ecosystem. Rabbits are lagomorph mammals that have spread around the whole globe. They have unique qualities such as their ears, eyes, and dewlap. By synchronizing their hind legs, rabbits jump at high speeds with precise directional control. Rabbits are herbivores, preferring tender and new growth over stems. The ideal environment for wild rabbits consists of an abundant food source, cover from predators, and decent dirt. However, rabbits can adapt to whatever environment. They have five different life stages and reproduce quickly. Rabbits are territorial creatures who will fight if needed, but their best chance of survival is escape. There are many natural predators of rabbits in the wild: mammals, reptiles, and raptors. This presentation will cover different aspects of wild and domestic rabbits and the complexity of this overlooked animal.

The Science of Cancer and the Preventable Mechanisms Behind It

Cancer is one of the most morbid killers across the globe, and its obliteration has been the focus of thousands of studies over the past 250 years. And while the vast majority of cancers are caused by a myriad of ineluctable factors, such as growth and inheritance, over a third of cancer deaths are attributable to multitudinous preventable causes, such as poor lifestyle choices, contraction of certain viruses, usage of tobacco and alcohol, among other factors. As such, this presentation seeks to explain the underlying mechanisms of cancer, along with the precise means by which these preventable carcinogenic factors promote its emergence.

CRISPR

Clustered regularly interspaced short palindromic repeats, Crispr for short is a dna sequence that can be used by the cas9 system of rna guided nucleases that effectively cleaves the section of dna containing a specific genome to repair or alter that specified genome. The crispr system is an adaptive immune system that is used and regulated by microbes and cells to defend against foreign substances and viruses by recognizing and eliminating the specific dna sequence associated with that virus. Most crispr systems contain 20-24 regularly spaced palindromic bases separated by spacers. The crispr cassettes are found in almost every archeon and almost half of bacteria studied. This provides a wide range of uses for the cas9 system and adds to the versatility of the system. We can use this system to replicate and code for specific genomes in animals and further understand how their traits are coded and replicated, we can create complex models for human inherited diseases or cancers, it can also be used to pinpoint the cause for underlying genetic processes by genome wide screening of the dna in any human cell. The origin of crispr however is the most intriguing aspect of the system. Being a biological system that was discovered and not a human engineered system, the origin is not entirely clear.
