From my previous posts, it was mentioned that Zika rarely causes death, and hospitalization is also uncommon. So what is the most devastating effect of the Zika virus? It can cause  microcephaly in infants. When the virus first began to spread like wildfire in Brazil, Doctors were not very certain of the implications. However, what was observed, was that there was a raising number of microcephaly in infants. Based on further investigation, a link was established between the virus and microcephaly.  What is Microcephaly Microcephaly (my-kroh-SEF-uh-lee) is a rare neurological condition in which an infant's head is significantly smaller than the heads of other children of the same age and sex. Sometimes detected at birth, microcephaly usually is the result of the brain developing abnormally in the womb or not growing as it should after birth. Microcephaly can be caused by a variety of genetic and environmental factors. Children with microcephaly often have dev...

Biotechnology  is the application of biological organisms, systems, or processes by various industries to help in the improvement of the value of materials and organism such pharmaceuticals, crops, and livestock (ASC-Chemistry for life). Biotechnology is not a new concept. It can be dated back to more than 6000 years ago (Biotechnology Industry Taken from:  unidigest.com Organization) when man first began to breed and domesticate plants and animals. However, modern biotechnology involves more genetic engineering, where an organism's genome is altered. Because of this technology, Biotechnology may allow man to reshape the future of his planet. We may very well be able to reduce the imminent threat global climate change by modifying organisms so that they are better adapted to survive in their ecosystems, and improve quality of agricultural crops and livestock. With Genetic engineering, we may even be able to extend our lives, either by improving our diet and health care, ...
