A lithium-ion battery or Li-ion battery (abbreviated as LIB) is a type of rechargeable battery in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. Li-ion batteries use an intercalated lithium compound as one electrode material, compared to the metallic lithium used in a non-rechargeable lithium battery. The electrolyte, which allows for ionic movement, and the two electrodes are the constituent components of a lithium-ion battery cell.

A widely reported 2016 study in the Journal of the American Medical Association compared homicide rates in Florida following the passage of its ''stand your ground'' self-defense law to the rates in four control states, New Jersey, New York, Ohio and Virginia, which have no similar laws. It found that the law was associated with a 24.4% increase in homicide and a 31.6% increase in firearm-related homicide, but no change in rates of suicide or suicide by firearm, between 2005 and 2014. It noted that, ''(c)ircumstances unique to Florida may have contributed to our findings, including those that we could not identify,'' and ''(o)ur study examined the effect of the Florida law on homicide and homicide by firearm, not on crime and public safety''. The study was criticized by gun rights advocate John Lott's Crime Prevention Research Center for studying only one state. Gun enthusiast and attorney Andrew Branca, writing in National Review, criticized the study for not distinguishing between justifiable homicides and murder, and for relying solely on statutory laws while overlooking case law (i.e. Virginia) in determining the data set. The study was praised by Duke University professor Jeffrey Swanson for its use of other states as controls, saying ''(t)hey look at comparable trends in states that didn't pass the law and don't see the effect.''

The Berlin Wall (German: Berliner Mauer, pronounced (blin ma) ( listen)) was a guarded concrete barrier that physically and ideologically divided Berlin from 1961 to 1989. Constructed by the German Democratic Republic (GDR, East Germany), starting on 13 August 1961, the Wall cut off (by land) West Berlin from virtually all of surrounding East Germany and East Berlin until government officials opened it in November 1989. Its demolition officially began on 13 June 1990 and finished in 1992. The barrier included guard towers placed along large concrete walls, accompanied by a wide area (later known as the ''death strip'') that contained anti-vehicle trenches, ''fakir beds'' and other defenses. The Eastern Bloc portrayed the Wall as protecting its population from fascist elements conspiring to prevent the ''will of the people'' in building a socialist state in East Germany.
