The Chicken and the Egg Question – Ancient Mystery Finally Solved

Philosophers and fertility experts can rest easy as the age-old question, “Which came first, the chicken or the egg?” finally has an answer: The chicken.

The research comes from British scientists out of Sheffield and Warwick universities. It all boils down to one protein—ovocledidin-17 (OC-17)—that is only found inside a chicken’s ovaries, and is essential for eggshell formation.

Although the protein has been studied as part of eggshell development before, researchers used a super computer to ‘zoom-in’ while a shell was forming, and found that it actually serves as a catalyst. Sheffield Professor John Harding hopes that this will aid in designing new materials.

Well, that’s one mystery solved. But still no word yet on the meaning of life.

The Big Five personality traits

In contemporary psychology, the "Big Five" factors of personality are five broad domains or dimensions of personality which are used to describe human personality.

The Big five factors are Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism (OCEAN, or CANOE if rearranged). The Neuroticism factor is sometimes referred to as Emotional Stability. Some disagreement remains about how to interpret the Openness factor, which is sometimes called "Intellect". Each factor consists of a cluster of more specific traits that correlate together. For example, extraversion includes such related qualities as sociability, excitement seeking, impulsiveness, and positive emotions.
