3. A tomacco is originally a fictional hybrid fruit that is half tomato and half tobacco, from the 1999 episode ?E-I-E-I-(Annoyed Grunt)? of The Simpsons; the method used to create the tomacco in the episode is fictional. The tomacco became real when it was allegedly produced in 2003. Inspired by The Simpsons, Rob Baur of Lake Oswego, Oregon successfully grafted a tomato plant onto the roots of a tobacco plant, which was possible because both plants come from the same family.

4. Mucophagy (literally mucus-eating, also referred as picking one?s nose and eating it) is the consumption of the nasal mucus, boogers, and other detritus obtained from nose-picking. Some research suggests that mucophagy may be a natural and even healthy activity, which exposes the digestive system to bacteria accumulated in the mucus, thereby helping to strengthen the immune system.

5. A supernumerary nipple (also known as a third nipple) is an additional nipple occurring in mammals including humans. Often mistaken for moles, supernumerary nipples are diagnosed at a rate of 2% in females, less in males. The nipples appear along the two vertical ?milk lines? which start in the armpit on each side, run down through the typical nipples and end at the groin. They are classified into eight levels of completeness from a simple patch of hair to a milk-bearing breast in miniature.

6. Why spaghetti does not break in half, French physicists have found why an uncooked spaghetti can break into three, seven or even ten pieces, but rarely two. It?s because of elastic waves travelling along the pasta when dry spaghetti is bent and suddenly released at one end. And don?t think this is a minor discovery: the researchers think their findings can be applied to civil engineering to make structures like buildings and bridges more stable.

7. Smart bees find land mines, Buried land mines kill more than 15,000 people each year worldwide. At the current removal rate, it will take about 450 years to clear the world of undetected anti-personnel land mines. Now, researchers from several U.S. universities are training honey bees to locate buried land mines through odor detection.8. Baboons can tell the difference between English and French. Zoo keepers at Port Lympne wild animal park in Kent are having to learn French to communicate with the baboons which had been transferred from Paris zoo.
