In a rare subset of patients undergoing general anesthesia, the anesthetic is inadequate to keep the patient unconscious during an operation. This is a condition known as anesthesia awareness. The patient may feel the pain of surgery and hear the conversations of surgical staff but is often unable to communicate because a muscle relaxant or paralytic has also been administered. Having which hair color may indicate that someone will require a higher dose of anesthesia? Discuss

Marketers of the Space Pen claim that the writing implement can be used in zero gravity, upside down, underwater, over wet paper, at any angle, and in extreme temperatures. The pen, which was invented by American industrialist Paul C. Fisher, uses pressurized ink cartridges to force thixotropic ink through its tungsten carbide ballpoint. Though standard ballpoint pens can be used in space, both the American and Russian space programs use Fisher’s pen. Why is it dangerous to use pencils in space? 
Dissociative amnesia is a loss of personal memory caused by a severe psychological trauma. Because the amnesia does not result from physiological trauma, such as a brain injury or disease, it is often treated with psychological therapy. While dissociative amnesia is often associated with particular events or periods of time, in its most radical form there is a total abandonment of personal identity and memory. How was “truth serum” used to treat dissociative amnesia during World War II? 
The 2004 book Between a Rock and a Hard Place chronicles the experiences of Aron Ralston, an American mountain climber who survived a nearly fatal hike in the Utah desert. While Ralston was canyoneering alone in May 2003, his right forearm became trapped by a falling boulder. Unable to lift the rock, Ralston was forced to amputate his own arm in order to free himself. How many days did Ralston wait before beginning the terrible operation? 
Thales of Miletus, one of the Seven Wise Men of Greece, was a pre-Socratic philosopher and scientist. He is traditionally considered the first Western philosopher and a founder of geometry and abstract astronomy. As a philosophical materialist, Thales theorized that water was the first principle of all things. He speculated that the Earth floated on water, and so proposed an explanation for earthquakes. A capable astronomer, Thales is said to have predicted what celestial phenomenon in 585 BCE? 
A biome is a large community of plants and animals that occupies a distinct geographic region. Terrestrial biomes, typically defined by their climate and dominant vegetation, include grassland, tundra, desert, tropical rainforest, and deciduous and coniferous forests. The two basic aquatic biomes, freshwater and marine, can be further broken down into categories such as lakes and rivers or pelagic, benthic, and intertidal zones. At what latitudes does biodiversity generally increase? 
Anarchism, a political theory that favors the abolition of all forms of government, started a profound libertarian revolution throughout Spain. During the Spanish Civil War of the 1930s, Catalonia was established as an anarchist stronghold and much of the region’s economy was put under worker control: factories were run through worker committees, agrarian areas became collectivized, and even hotels and restaurants were managed by their workers. When did Catalonia fall to Spain’s nationalists? 
Though the US Environmental Protection Agency labeled perfluorooctanoic acid (PFOA) a likely carcinogen in 2006, it continues to be widely used in food packaging and in the processing of Teflon non-stick coatings. Traces of PFOA-family chemicals can now be found in the blood of most Americans and in the environment worldwide. Of particular concern is the grease resistant fluorotelomer coating used in the production of microwave popcorn packages. How does the PFOA from popcorn bags get ingested? 
In 1998, the United States signed The Copyright Term Extension Act into law, thereby extending the copyright terms set forth in the international Berne Convention of 1886. The act increased America’s term of protection for copyrighted works by 20 years. Sonny Bono, a songwriter, filmmaker, and congressman, was a major proponent of copyright extension, and the act, passed nine months after his death, was named in his honor. Why is the act pejoratively known as the Mickey Mouse Protection Act? 
In 1939, Nazi forces staged an attack on a German radio station and planted the bullet-riddled body of a Polish sympathizer at the scene, reporting the attack as the work of Polish saboteurs. The attack was part of a Nazi propaganda campaign called Operation Himmler, which involved a series of staged incidents intended to create the appearance of Polish aggression against Germany and provide a basis for the subsequent invasion of Poland. What was Hitler quoted as having said about the campaign?
