On average, male skeletons are larger than female skeletons, but just as some women are larger than some males, this distinction does not hold firm in all instances. Female pelvic regions tend to be wider than male pelvic regions, an evolutionary feature that has made childbirth easier. Female bones tend to be thinner and less dense than male bones, and thus the female skeleton tends to be lighter than male skeletons. The skull is one of the most notable sites of difference between male and female skeletons. The teeth of males tend to be larger, and above their eye sockets men tend to have a more visible brow ridge while women often have none. The male skull tends to have a squarer (as opposed to a pointed) chin and is more angular in its demarcations than the female skull. Women's nose openings are more apt to be pointed, rather than blunt as in a male. "The adult female skull retains" some of the attributes "seen in the pre-pubescent [male] skull, but the male cranium becomes markedly rougher in...
Females also tend to have longer upper arm regions, while males tend to have shorter upper arm regions in proportion to their lower arms (Richards 2000).
Dimitrios Karussis and Ibrahim Kassis, in the article, "Use of Stem Cells for Treatment of Multiple Sclerosis," conclude, "In the current review, the various types of stem cells, which were mainly studied in animal models, will be reviewed as a potential therapeutic approach for MS. The main and common mechanisms of action of all stem cells include induction of neuroregeneration and remyelination through the activation of resident stem cells, or
In the words of Obama, "Today, with the executive order I am about to sign, we will bring the change that so many scientists and researchers, doctors and innovators, patients and loved ones have hoped for, and fought for, these past eight years: We will lift the ban on federal funding for promising embryonic stem cell research," President Obama further said.

This bill was sent to the U.S. Senate and set for vote mirroring a bill previously passed by the House during the Summer of 2003 which failed to pass the Senate because of vehement disagreement that was even "within the parties over the prohibition of therapeutic cloning.(National Legislation Concerning Human and Reproductive Cloning, 2004; paraphrased) As of the date of the report on legislation eight U.S. states had passed
Ian Wimut and Keith Campbell could effectively clone two sheeps named Megan and Morag in July 1995 from the differentiated embryo cells. (History of Cloning) Dolly originated on July 5, 1996 as the first organism ever to be cloned from adult cells. Following the announcements for creation of Dolly by Ian Wilmut, an extensive debate on human cloning ethics emerged and that led President Clinton to propose for a five-year
Colorectal cancer is said to be one of the most common cancers in the U.S. In this text, I largely concern myself with this type of cancer. In so doing, I will amongst other things take into consideration not only its pathophysiology but also its clinical manifestations, treatment options, interventions, and expected outcomes. Colorectal Cancer: A Brief Overview The Centers for Disease Control and Prevention -- CDC (2011) observes that "of cancers
Figure 1 portrays three of the scenes 20/20 presented March 15, 2010. Figure 1: Heather, Rachel, and Unnamed Girl in 20/20 Program (adapted from Stossel, 2010). Statement of the Problem For any individual, the death of a family member, friend, parent or sibling may often be overwhelming. For adolescents, the death of person close to them may prove much more traumatic as it can disrupt adolescent development. Diana Mahoney (2008), with the
