At Banaras Hindu University in India zoologist scientist were working on research on the changes in stress and life traits in fruit flies. The scientists‚ Seema Sisodia‚ Puja Verma and Bashisth Narayan Sing explain there research in “The Effect of Diet Quality and Associated Metabolic Changes in Adult Stress Response and Life-History Traits in Drosophila Ananassae” The D. ananassae used in the experiment are flies collected from fruit and vegetable india in October 2010. The purpose of the study

The novel Fledgling by Octavia Butler analyses race relations and eugenics in society. Through the use of another intelligent species Butler lets the reader experience what happens when humans are not at the top of the food chain. While making the reader question the controversy over the use of eugenics and genetic engineering‚ Butler uses the story as a parallel of race relations in America. In society today‚ there is a debate over eugenics‚ whether humans should be looking into genetic engineering

First‚ where do stem cells come from‚ and what properties do they exhibit that make them stem cells? Human embryonic stem cells come from an embryo that develops from an egg. These eggs were originally collected for reproductive purposes. The eggs are fertilized in vitro‚ and the embryo is donated for research. The donation only happens after the eggs are no longer needed. The donor is informed of the intended use‚ and consent has been given. These stem cells are found when the embryo is between

Xenotransplantation is a procedure that is focused on the transferring of organs from one species to another. The application of this scientific technology converging human beings and animals‚ configures much controversy amidst the substantial benefits and detriments that xenotransplantation yields. Signifying‚ that through an attempt to reach an agreement on xenotransplantation’s bioethical debate‚ a mold of various frameworks of ethical perspectives on the topic is constructed. In this case‚ it

When faced with the two distinct species of salamander‚ one must ask what their common ancestor looked like and whether it primarily lived in ponds or streams. Previous studies have presumed that Ambystoma barbouri‚ the stream dwelling species‚ is divergent from Ambystoma texanum‚ the pond dwelling species (Kraus and Petranka‚ 1989). This assumption is based on knowledge of environmental changes and the geographic spread of each species. Since the end of the last Ice Age‚ the availability of pond

CRISPR is a revolutionary technique that edits genes‚ enabling humans to select desirable genetic traits. Although this idea of editing genes of human embryos may sound advantageous‚ editing genes can prove to be dangerous and can leads to dire consequences. Practicing CRISPR on human embryos can also violates the fundamental idea of civil rights. By implementing CRISPR and eliminating genes that we found unfavorable‚ we are essentially eliminating the diversity of the human gene pools and human

The military agency that turns dreams into reality‚ DARPA‚ is investing into building materials that will actually grow and repair themselves if they’re damaged. Like Wolverine from X-Men‚ but your roof after a hail storm. Let’s face it: going back and forth from hardware stores to fix crap that went wrong in your house is tiring. Your house needs constant maintenance‚ or else your house becomes the house that parents warn their kids not to go near because it looks like Jason Voorhees lives there

Neuroscientists at Emory University found that genetic markers‚ thought to be wiped clean before birth‚ were used to transmit a single traumatic experience across generations‚ leaving behind traces in the behavior and anatomy of future pups. Studies that show how molecules act as DNA markers that influence how the genome is read are known as epigenetic. We pick up these markers during our lives and in various locations on our body as we develop and interact with our environment. Through a process

Most of us agree that the course of life should be left up to Mother Nature‚ just the way it has been since the beggining of time; meanwhile‚ cloning may be seen as another advance in science research and technology. Indeed‚ many consider this matter as one of the biggest ethical concerns of the 21st century. We know that they have been trying it since the last century. But until now‚ it hasn’t succeeded. For example‚ the technique which produced Dolly (the sheep) was successful in only 1 of 277

world’s first mammal successfully cloned from an adult‚ brought hope and prosperity among scientists who view cloning as a potential cure for illnesses and other beneficial uses. The birth of Dolly represented a milestone in genetic technology but caused an enormous amount of uproar from the public. The historic event prompted a raging debate about the ethics and consequences of cloning‚ especially when using the same technique to clone human beings. Many people considered attempting to clone a human
