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

experimentation has always been a topic of controversy‚ and it’s been performed for centuries. In the past century‚ countries have began to illegalize to call it unethical. Many events have occurred that led to the downfall of human experimentation. From HeLa cells to unethical studies to the lives of many people being ruined. When human experimentation became a hot topic several decades ago‚ many scientists supported it because they believed it would be the only way for medicine to advance. In the US‚ once the

According to the article‚ some neuroscientists are “zooming in on the fine structure of individual nerve cells‚ or neurons”‚ while others are using biochemistry to chart the brain to see how neurons produce different kinds of proteins. Others are trying to create detail to represent the brain’s wiring. Through all of these tests‚ scientists are getting a better

“Equipped with his five senses‚ man explores the universe around him and calls the adventure Science‚” According to Edwin Powell Hubble. Science has been expanding and more advanced with today’s technology. Scientific advancements are also making good and bad effects and not everyone agrees with all of them. Cloning is one of the scientific advancements that is expanding and it happens for many different reasons and it has many different effects on society. When scientist clone a certain animal

The question of cloning humans sounds morally unethical‚ right? It doesn’t seem even today with our scientific technology or knowledge‚ that we could pull something that extraordinary off. In the novel by Kazuo Ishiguro “Never Let Me Go” we learn that the setting takes place in a world where there are clones of people who must donate their vital organs to non clones. Basically their life is setup to donate then “complete” which indefinitely means to die. There are three “donations” which take place

Based on this article by Sandeep Ravindran titled “A Squirt of Stem Cell Gel Heals Brain Injuries‚” it can be inferred in Sandeep’s thesis that it is just a matter of time.
