\"olive-oil2\"<\/a>The Difference Between \u201cRegular\u201d, Virgin and Extra Virgin Olive Oils<\/a><\/p>\n

Generally speaking, olive oils fall into one of two broad categories: refined and unrefined, with virgin and extra virgin fitting in the latter category, and pure and light olive oils in the former.\u00a0Olives used to make the two virgin, unrefined oils aren\u2019t treated with heat or chemicals, but, rather, are cold pressed; as the name implies, this means the olives are simply pressed and squeezed to get the oil out.\u00a0Those olives that produce the highest quality oil in terms of rich taste (though flavor can still vary wildly based on a variety of factors) and acidity make extra virgin olive oil, while slightly riper olives, that are also simply just pressed, produce virgin olive oil. In terms of acidity…(more<\/a>)<\/p>\n

\"mosquito2\"<\/a>Why are Mosquitoes More Attracted to Some People than Others?<\/a><\/p>\n

Female mosquitoes can put a damper on any outdoor event when they start to snack on those present. (Note: only the females drink your blood; they don\u2019t need it for their own nourishment, but for certain nutrients necessary to develop their eggs<\/a>). Certain peopleseem<\/em> to be swatting the insects away or ending the night with more red bites than others. So is it true that some people really are more \u201cattractive\u201d to mosquitoes, and, if so, why is this the case?\u00a0To answer the first question- yes, some people do attract mosquitoes more than others at certain times.\u00a0 As for the answer to why this is the case, there are numerous factors involved.\u00a0 Beyond the several hundred chemical odors that have been identified to date that the human body gives off…(more<\/a>)<\/p>\n

\"clapping\"<\/a>When Did People First Start Clapping to Show Appreciation?<\/a><\/p>\n

Clapping is the near-ubiquitous way we show our appreciation of something, particularly when we\u2019re in large groups. But have you ever wondered why slapping our hands together has come to be so closely associated with approval and where the practise originated from?To begin with, the idea of clapping to show appreciation is a learned behavior. Babies generally start clapping before they are one year old, but without encouragement from parents, this tends to be a behavior that isn\u2019t often used, and certainly not to show appreciation- simply that the baby discovers it can make a noise with its hands and for a time becomes fascinated by this. From here, parents usually begin (whether consciously or not) teaching them to use this motion and sound to show enthusiasm…(more<\/a>)<\/p>\n

\"Jello-Fruit-Desert\"<\/a>Why Can\u2019t You Put Pineapple in Jello? <\/a><\/p>\n

Unless you\u2019ve managed to make it this far in life without setting foot in a store, you\u2019re probably aware that jello, popularly known as jelly by my British compatriots, is a genericization of the brand Jell-O which itself was derived from the word \u201cgelatin\u201d. (See: The Jiggly History of Jell-O) Gelatin is a protein derived from collagen via a process called hydrolysis, which breaks apart the bonds of this protein with water.\u00a0While hydrolysis may sound complicated, it\u2019s simply a matter of boiling collagen rich animal byproducts, usually bones, connective tissue and skin, in water for many hours to break it down. The resulting broth is then carefully strained before the water is evaporated, leaving behind gelatin which can either be pressed into sheets or sold as a powder. Given that it is made from animal byproducts, gelatin and products containing it aren\u2019t considered to be vegetarian and as a result…(more<\/a>)<\/p>\n
