IN: World War I was the first major conflict involving the large-scale use of aircraft. Tethered observation balloons had already been employed in several wars, and would be used extensively for artillery spotting. Germany employed Zeppelins for reconnaissance over the North Sea and Baltic and also for strategic bombing raids over Britain and the Eastern Front.

IN: The Federal Assault Weapons Ban enacted in 1994 expired in 2004. Attempts to renew this ban have failed, as have attempts to pass a new ban, such as the Assault Weapons Ban of 2013 (AWB 2013). Seven U.S. states have assault weapons bans: three were enacted before the 1994 federal ban and four more passed before the federal ban expired. The majority of states, forty-three, have no assault weapons ban, although two, Minnesota and Virginia, have training and background check requirements for purchasers of assault weapons that are more stringent than those for ordinary firearms. While there are no statewide assault weapon bans in Colorado and Illinois, local bans exist in certain cities or counties in each of these states. In 2018, most Americans supported a ban on assault weapons, according to polls.

IN: The Xbox was the first video game console to feature a built-in hard disk drive, used primarily for storing game saves and content downloaded from Xbox Live. This eliminated the need for separate memory cards (although some older consoles, such as the Amiga CD32, used internal flash memory, and others, like the TurboGrafx-CD, Sega CD, and Sega Saturn, had featured built-in battery backup memory prior to 2001). An Xbox user could rip music from standard audio CDs to the hard drive, and these songs were used for the custom soundtracks in some games.

IN: All white blood cells have nuclei, which distinguishes them from the other blood cells, the anucleated red blood cells (RBCs) and platelets. Types of white blood cells can be classified in standard ways. Two pairs of broadest categories classify them either by structure (granulocytes or agranulocytes) or by cell division lineage (myeloid cells or lymphoid cells). These broadest categories can be further divided into the five main types: neutrophils, eosinophils (acidophilus), basophils, lymphocytes, and monocytes. These types are distinguished by their physical and functional characteristics. Monocytes and neutrophils are phagocytic. Further subtypes can be classified; for example, among lymphocytes, there are B cells, T cells, and NK cells.
