De-extinction of the Thylacine 
Loading...
Abstract
Loading...
Currently, thousands of animal species go extinct each year. This is due to a variety of reasons, such as the natural process of out competition and the changing climate cycle. However, due to human interference, species extinctions have accelerated to an unprecedented rate. Human activities such as the expansion of human settlements, targeted hunting, and the spreading of invasive species are all reasons for this acceleration. The effects from humans can, however, be reversed by de-extinction. De-extinction is the process where an extinct species is repopulated. This project seeks to look at ways this process could be carried out through back-breeding or Somatic Cell Nuclear Transfer (SCNT). Choosing a species for the de-extinction process requires some careful selection and the consideration of many issues. An animal that might be a good candidate for the de-extinction process is the Thylacine or Thylacinus cynocephalus. This project will explore the history of this animal and examine some of the positives and negatives of two possible procedures that could be undertaken to bring the Thylacine back, back-breeding and SCNT. With the evidence provided, SCNT will prove to be the more plausible option.

A Look into Topology with a Theory on the Square Peg Problem
Loading...
Abstract
Loading...
In 1911, topology professors Toeplitz and Emch both posed similar conjectures for their students to prove: Does every simple closed curve contain the four vertices of a square on its perimeter? This problem, now dubbed the Inscribed Square Problem, although simply written, has yet to be solved completely. There have been increasingly general limitations that have been applied to provide partial solution sets, but there has yet to be a single general solution. Based on the work of Igor Pak on the inscribed rectangle problem, and the application of related work by Meyerson, this research suggests a new approach to this problem. Like Pak, this involves the use of a three-dimensional projection of a subset of points that lie on the perimeter of the curve. Although a conclusion will be drawn, there has been no rigorous testing applied to the theory to ensure that it holds true in the general case. Use of mathematical models, both algebraic and computational, are needed to verify the theory. This project is meant to provide a new approach to the problem, one that may be applicable to a more rigorous objective proof and widens the view of the problem to more geometric, rather than analytic, perspectives.
