Extremophiles are microorganisms that thrive in environments with extreme conditions, such as high or low temperatures or pH levels, high salt concentration, or high pressure. Found in hydrothermal vents on the ocean floor, they produce the vivid colors of some hot springs. Due to extremophiles' ability to thrive in conditions detrimental to most life on Earth, some scientists theorize that they may reflect what life may be like on other planets. How are extremophiles used industrially?

At age 14, African-American Emmett Till was murdered in Mississippi after reportedly whistling at a white woman, Carolyn Bryant, in a grocery store. Her husband and his half-brother beat Till, shot him in the head, and dumped his body in the Tallahatchie River, weighing it down by tying a metal fan around his neck with barbed wire. Till's body was pulled from the river three days later. What decision made by Till's mother about her son's funeral helped bring attention to his brutal murder?

Though less widely known than his contemporaries Thomas Edison and Gustave Eiffel, Russian engineer, scientist, and architect Vladimir Shukhov has drawn comparisons to both of them. His innovations in the petroleum refining process and the means of transporting petroleum products revolutionized the oil industry, while his architectural works were of a sort never seen before. He pioneered the construction of thin-shell and tensile structures as well as what innovative type of curved structure?
