Genetics and biotechnology have had and continue to impact our lives in a lot of ways. But just like any other technology, biotechnology raises also raises issues of ethics. Ethical issues that often impact social policy, environment and the law. In this essay, we will consider some ethical issues of biotechnology, from a historical perspective, we will also look at some of the issues … Continue reading Ethical Issues in Genome Editing
Anthrax Anthrax is an infection that is caused by the gram-positive bacteria called Bacillus Anthracis. Anthrax can either be cutaneous, gastrointestinal or inhalation. History Anthrax was known by the names wool sorters and rag-pickers disease in 1800. This was because workers used to contract the disease through bacterial spores present in wool or fabric fibres. Spores are small thick-walled in the dormant stage of some … Continue reading Explainer | What is Anthrax and why is it dangerous?
Jiankui He claims he has used CRISPR to edit the genomes of twin girls. Merlin Crossley, Author provided Merlin Crossley, UNSW I am currently at the Second International Summit on Human Genome Editing, where controversial CRIPSR scientist Jiankui He presented his research just a few hours ago. He also answered questions from gene experts Robin Lovell-Badge (Crick Institute) and Matt Porteus (Stanford), plus assembled … Continue reading Tension as scientist at centre of CRIPSR outrage speaks at genome editing summit
Fluid and Nutritional imbalance in children and young people Children have a higher metabolism so they need more calories and fluid for growth The intestinal tract in children is larger per body weight compared to adults. Gastric acid secretion reaches adult levels by 10 years of age. Infants have a short oesophagus At three months pancreatic juice contains low levels of lipase Nutritional assessments Is … Continue reading Fluid and Nutritional Imbalance in Children
The sonic hedgehog gene is the human form of the hedgehog superfamily of inductive molecules that play a role in the development of the embryo. The action of the hedgehog gene was first observed in the Drosophila, recent studies have found members of the gene in metazoan, sea urchin, leech, and beetle (Sudhir bar 1995). This is according to an experiment that was done … Continue reading The Sonic Hedgehog Gene
The female reproductive system is made up of the gonads, duct system and accessory glands. Produces garments and transports them for fertilisation, the process of birth and nurturing. When the oocyte is matured it is expelled from the ovaries and then travels down the fallopian tube. Eggs pass through the fallopian tube to the uterus where they are fertilised. They burrow into the walls of the … Continue reading Explainer| The Menstrual cycle
Press release 21 August 2018 Cancer Research UK news_lab-1.jpg Scientists have identified a key molecular player in a subtype of lung cancer which could lead to a new way to tackle the disease, according to research published in Nature Communications. “How LUSC develops is a bit of puzzle – until now our molecular understanding of this process was limited. Our research has revealed a major piece of … Continue reading Scientists discover first step towards finding a new, targeted lung cancer treatment
