Many articles have been and are being written about studies that show new knowledge or could potentially lead to a big discovery. Just one example would be where emotions and reactions come from inside the brain.
Similarly, development of research and gains in knowledge is vital to knowing how fear is caused and where it starts. Also, researchers use this knowledge to find ways to prevent fear of certain things.
