For the first time during the Vietnam War, television made it possible for Americans to be transported to Vietnam all while in…

nicknamed by NATO reports as “Bear” is a strategic bomber and missile platform. It was designed during the Cold War and entered service in 1956. Reports from the Russian Air Force (RAF) expect it to serve until at least 2040. In its design, the propeller-blades move faster than the speed of sound which cements its position as one of the nosiest military aircrafts. Due to its size, sizable crews of 6-7 men are needed to successfully operate it. As it stands now the TU-95 is a glaring reminder of…

Unfortunately, Oscar Webb, a 16-month old toddler who was playing in his front yard, was not so lucky as his eyeball was sliced in half from a drone propeller. The accident was caused by a drone that spiraled out of control because it clipped a tree branch while it was descending, causing it to fly directly into Oscar. This preventable accident will forever impact this toddler's life as he will never…

Microtubules, which are made of protein subunits called tubulin, are the thickest of all three cytoskeletal filaments. Microtubules are mainly serving as the paths along which vesicles are guided in their travels to various destinations, and are responsible for associating with motor proteins attached to the vesicles. Microtubules can also expand or shrink in length in order to establish dynamic structures that can efficiently change the internal organization of the cell, and capture organelles…
