#1. What is the medical term for the cartilage in the nose which separates the nostrils?

The septum is the bone and cartilage that separates the right and left sides of the nasal cavity.

#2. What chemical element gets its name from the greek word meaning 'stranger'?

XENON Like xenophobia, xenon takes its name from a Greek word, xenos, meaning “strange” or “foreign.

#3. In relation to its size, which bird has, understandably, the thickest skull?

Studies suggest that a woodpecker can strike a tree with its chisel-like beak several hundred times per minute, up to 12,000 times in a single day, and with a force 1,000 times that of gravity. It may seem strange for a woodpecker’s tongue to wrap around its skull, but this adaptation serves a far greater purpose than simple storage. The muscles of the tongue actually help insulate a woodpecker’s brain from the shock of repeated pecks, decreasing its chances of developing serious brain injuries.

#4. "I shall please" is the Latin translation of what medical treatment?

The word “placebo” is Latin for “I shall please.” In medieval times it was the first word of (and name for) a prayer chanted over the dead, and became a derogatory name for the mourners who were hired to do the chanting. By the 18th century, “placebo” was a term for any commonplace medical remedy. By the early 19th century, a medical dictionary defined the word as “any medicine adopted more to please than benefit the patient.”

#5. What does the body release that dilates small blood vessels and so causes a person to blush?

Adrenaline is responsible for all of these emergency response measures. The body’s natural stimulant, adrenaline increases your breathing rate, and causes your pupils to dilate. It also causes the blood vessels deep in your muscles to dilate, in order to get more oxygen and more energy where it’s needed most. The veins in your face also dilate. As they open up allowing more blood to flow, your cheeks become warmer and redder. You’re blushing.

#6. What animal, related to the hyena, has a name meaning "earth-wolf" in Afrikaans and Dutch?

The aardwolf  is a small, insectivorous mammal, native to East and Southern Africa. Its name means “earth wolf” in Afrikaans and Dutch. It is also called “maanhaar jackal” (Afrikaans for “mane jackal”) or civet hyena, based on the secretions from their anal glands, reminiscent of civets.

#7. Credited with the invention of the nuclear reactor, who won the 1938 Nobel Prize for Physics for his work on radioactive elements?

The Nobel Prize in Physics 1938 was awarded to Enrico Fermi “for his demonstrations of the existence of new radioactive elements produced by neutron irradiation, and for his related discovery of nuclear reactions brought about by slow neutrons.”

#8. What branch of science studies the motion of air and the forces acting on objects in air?

Aerodynamics, branch of physics that deals with the motion of air and other gaseous fluids and with the forces acting on bodies passing through such a fluid. Aerodynamics seeks, in particular, to explain the principles governing the flight of aircraft, rockets, and missiles.

#9. The ore bauxite is the chief commercial source of which element?

Bauxite ore is the world’s primary source of aluminum. The ore must first be chemically processed to produce alumina (aluminum oxide). Alumina is then smelted using an electrolysis process to produce pure aluminum metal. Bauxite is typically found in topsoil located in various tropical and subtropical regions

#10. In 1953 Science fiction author L.Ron Hubbard founded which cult religion, with modern day followers including many celebrities?

Scientology is a set of beliefs and practices invented by American author L. Ron Hubbard, and an associated movement. It has been variously defined as a cult, a business or a new religious movement. Hubbard initially developed a set of ideas which he represented as a form of therapy, called Dianetics. This he promoted through various publications, and through the Hubbard Dianetic Research Foundation, which he established in 1950. The foundation soon entered bankruptcy, and Hubbard lost the rights to his book Dianetics: The Modern Science of Mental Health in 1952. He then recharacterized the subject as a religion and renamed it Scientology,retaining the terminology, doctrines, and the practice of “auditing”. Within a year, he regained the rights to Dianetics and retained both subjects under the umbrella of the Church of Scientology.
