Coping with Unexplained Fertility If you and your partner have trouble conceiving for six months to a year, you might think you have a fertility problem. Your next step is to go to a clinic and get tested for infertility symptoms. If these tests result in no answers, you are diagnosed with unexplained infertility. According to the Center for Human Reproduction, around 30% of women diagnosed with infertility are thought to have unexplained infertility. The CHS believe this is a “misleading faux

When Does Human Life Begin? The question, “when does human life begin,” is no doubt a widely discussed and debated question that has deepened throughout the ages with the progression of new technology and knowledge in scientific fields. Growing up in a Christian environment you often hear verses like Jeremiah 1:5, “Before I formed you in the womb I knew you, and before you were born I consecrated you; I appointed you a prophet to the nations,” have been enough to satisfy many believers, like myself

Introduction –*Amphioxus, commonly known as Lancet, is the best known example of a protochordate *It was first described by Palias (1778) who considered it to be a Mollusc and named it Limax lanceolatus. *Costa (1834) described it as a chordateand named it as ‘Branchistoma’. In 1836, Yarrell (1836) named it as Amphioxus lanceolatus.

In the article, "Scientists seek permission to genetically modify embryos.” United Kingdom scientist are permitted to do genome modifications under a license without implantation; in line with Human Fertilization and Embryology Authority (HFEA) regulations. The proclaimed aim is to understand the genetics that a human embryo needs to successfully develop. However, implantation of IVF test embryos is illegal under British law. UK Scientist push for it to be permissible in a clinical setting one day

Before the Scientific Revolution began to take shape around the year 1550, the world of science was exceedingly narrow and thought to be known. The scientific views of the pre-scientific revolution stem back even further than the popular Aristotelian era of science. Hippocrates contributed greatly to the field of science, especially in the field of medicine. It was during his years of medical studies that Hippocrates theorized the “Four Temperaments”. This theory hypothesized that there are four

Polycystic ovary syndrome (PCOS), was first described in 1935 and named Stein-Levinthal syndrome after the doctors who noted the characteristic body changes and tiny cysts covering the ovaries. Although the first observation was made as early as 1721, when Italian scientist Antonio Vallisneri observed “young married peasant women, moderately obese and infertile, with two larger than normal ovaries, bumpy and shiny, whitish, just like pigeon eggs” (Kovacs, 2002). It was not until 1921 that Achard

Explanation of the concept of natural selection and how it takes place - Natural selection is the process where organisms that have more advantageous adaptions that benefit its survival in its environment then breed and produce offspring with similar traits that then have a greater chance of survival. For natural selection to occur there are essential elements that are required; variation, heritability and excess production. For the formation of a new species there must be variation within a species

of the discussion on abortion revolves around the issue of personhood. However more fundamental than that is the question of humanhood. If it can be shown that the unborn are human beings, then killing them would be morally wrong. The science of embryology is very clear on this matter. It tells us that the development of a human begins with fertilization, a process by which the spermatozoon and the oocyte unite to give rise to a new organism, the zygote (Sadler, T.W., 1995). So, assuming that this

Neonatal Surgeon The job I would like to do when I am older is neonatal surgery. I think neonatal surgery is a wonderful profession for me because I love babies. This job entails working with and performing life saving surgeries to premature babies, or babies with birth defects. I feel as though this job is a gift because you’re giving life to another human and also giving them another chance at life. Wanting to be a Neonatal Surgeon, I have to set goals for myself to reach my overall objective

classified as a scientific theory because there is still some evidence needed so that evolution can be proven true. The evidence scientists have regarding evolution to lead to the conclusion that evolution is a reliable-theory are, relative dating,embryology, and homologous structures. The purpose of this lab was to learn the way in which human ancestors evolved into today’s human species. My hypothesis is that if the Foramen Magnum in located at the bottom of the skull of the organism being studied
