What Can CRISPR Do?

CRISPR is a revolutionary gene-editing tool that has taken the scientific community by storm. Here is a list of 5 interesting ways CRISPR has been used, outside of the medical field. 1. Hercules the Super-dog The world's first genetically engineered dog Hercules, was created by Chinese scientists to have the gene myostatin turned off. Myostatin regulates the amount of muscle fibers produces, and without this break, the body doesn't know when to stop. How do you feel about designer pets? 2. Gender Reassignment of Mosquitos  Researches from a lab in Blacksburg, Virginia, have identified the gene responsible for gender determination. Using CRISPR they then played around with gender within mosquito populations.  This work actually has a very serious motivation. Only female mosquitos can bite and transmit diseases, therefore the researchers in the lab are trying to build up large populations of sterile male mosquitos to release into the wild. This has the potential to dramatically ...

Genetic Engineering in Agriculture: the Good and the Bad

Genetic engineering is the intersection of technology and nature in an attempt to create the best possible outcome. The process of genetic engineering alters the structure of genes through direct manipulation of an organisms genetic material. DNA is either added or removed, this process produces traits, that weren't found in the organism before the engineering. Genetic material has revolutionized agriculture in a way that cannot take place naturally or with selective breeding.  Gene editing also allows for herbicide resistant plants. It also produces plants with a resistance to infestations or droughts. The main benefit of GMO crops is how it impacts people, allowing more people to enjoy meals, without having to worry about certain environmental factors, due to increased crop yields, from hardier crops. The pros of genetic engineering in agriculture heavily relies on this. However, a small population are looking into the dangerous propositions of this technology.  The technolo...
