Are We Animals?
Are We Animals? _____ Man versus polar bear: _ Keeper Julius Latoya shares a tender moment with Kinna, a young orphaned African elephant at the David Sheldrick Wildlife Trust in Tsavo East National Park, Kenya. ______ ______ Section-1 Prologue: Many parents admonish their misbehaving children by saying “stop acting like animals” implying that children are acting in a primitive and thoughtless manner. When my students/patients misbehave, I occasionally tell them that they are behaving like animals. Of course, my critics in India would label my utterances as racist and dehumanizing akin to the Nazis’ persecution of Jews during the Holocaust and torture at the Abu Ghraib prison in Iraq. Many patients hospitalized in some Covid-19 facilities in India complained that their condition was like “animals” at the facility. Most of us grew up eating meat, wearing leather, and going to circuses and zoos. Many of […]
SYNTHETIC BIOLOGY (SYNBIO)
Synthetic Biology (synbio): _______ Scientists Elizabeth Allman and Kristin O’Brien teach a course in synthetic biology at the University of Alaska Fairbanks. O’Brien said that the goal of synthetic biology is not to build “better organisms” but rather to create biological machines. _______ Prologue: The advent of digital technology is considered one of the biggest revolutions of all time for how quickly and deeply it changed the world forever. Even more powerful revolution is coming, which goes under the name of synthetic biology. The potential of this discipline is very well understood in the biological scientific world. It is time I make general public aware of the impact it will have on our lives. Synthetic biology brings together a bewildering number of disciplines: biotechnology, molecular biology, systems biology, biophysics, computer engineering, genetic engineering, and more. Synthetic biology will allow scientists and engineers to create biological systems that do not occur […]
GENE THERAPY
_______ GENE THERAPY: ______ ______ Caveat: Medicine is an ever-changing science. As new research and clinical experience broaden our knowledge, changes in treatment and drug therapy are required. I have checked with sources believed to be reliable in their efforts to provide information that is complete and generally in accord with the standards accepted at the time of publishing this article. However, in view of the possibility of human error or changes in medical sciences, I do not assure that the information contained herein is in every respect accurate or complete, and I disclaim all responsibility for any errors or omissions or for the results obtained from use of the information contained in this work. Readers are encouraged to confirm the information contained herein with other sources. I have taken some information from articles that were published few years ago.

THE DEATH
THE DEATH Prologue: As a student of medicine, since I joined medical college in the year 1978, I have been a witness to death either in the form of dissecting a dead body or declaring someone dead. The dissecting cadaver (corpse) is a critical component of every medical education. Without the anatomical understanding of the human body that is afforded by dissection, much of modern medicine would simply not exist. I also remember a very difficult task of informing a crying mother that her only son died of poisoning. Hundreds of patients have died before me in my experience as a doctor. Many times my junior doctors have expressed apprehension of declaring someone dead because they were afraid that patient may still be alive and I used to teach them signs of death like unconsciousness, no response to any stimulus, no breathing, no pulse and no heart beat on […]
GENETICALLY MODIFIED
GENETICALLY MODIFIED (GM): Prologue: A year 2006 study of the global impact of GM crops, published by the UK consultancy PG Economics and funded by Illinois-Missouri Biotechnology Alliance concluded that globally, the technology reduced pesticide spraying by 286,000 tons in 2006, decreasing the environmental impact of herbicides and pesticides by 15%. On the other hand, a year 2009 study published by the Organic Center stated that the use of genetically engineered corn, soybean, and cotton increased the use of herbicides by 383 million pounds, and pesticide use by 318.4 million pounds. Whom to trust? This is the paradox about GM food. There are thousands of studies and research works on GM whose conclusions contradict each other. People are caught in the cross-fire between pro-GM lobby and anti-GM lobby. I do not know the truth but I will try to educate people on the most controversial issue of 21’st century. […]
