A Taste of Things to ComeHave you ever heard of a “supertaster”? No, that’s not a long-lost member of the Justice League with a heightened sense of taste. A supertaster is someone with a higher taste response than the majority people. Psychologist Linda Bartoshuk discovered that about one-fourth of the population is super-sensitive to bitter tastes in foods such as coffee, grapefruits, and green vegetables as a result of a duplicate of a particular gene. Bartoshuk also found that non-tasters, or people with senses of taste that are much less sensitive than average, make up another fourth of the population. This means that genes are partially responsible for differing perceptions of taste.
Charles Spence, the Director of the Crossmodal Research Lab, part of Oxford University’s Department of Experimental Psychology, determined that other senses and moods affect taste. Experimenters have found that wine experts can be fooled into perceiving that the same white wine has a different flavor if the wine’s color is altered with food coloring. Another experiment revealed that carrots are perceived as tasting worse if they lose their crunch. Finally, Lucy Donaldson, a senior lecturer in physiology and pharmacology at the University of Bristol, reports that “Anxiety and depression can make things taste of cardboard.…The brain actually activates what happens on the tongue.”
Such findings are more than just fascinating; they can change the entire way certain products are marketed. Spence explains, “Already in some markets, such as toothpaste, companies have multiple brands that are targeted at supertasters or non-tasters.” Restaurants with “experimental chefs” are considering serving an amuse-bouche, gauging patrons’ reactions, and adjusting the following courses to their preferences. The reasoning behind these alterations is simple: give the people what they want. Since everyone perceives taste differently, it is only logical for purveyors to provide multiple options to ensure that each taster has the best tasting experience possible, no matter whether he is color-blind, depressed, a non-taster, or a supertaster.

Europe’s First “Import”ant Cultural Practice The origin of farming in Europe approximately 8,000 years ago is considered to be the most important nexus of survival instincts and social structure in the evolution of human culture. Traditionally, hunter-gatherer tribes in Europe were believed to have developed the practices of crop cultivation and animal husbandry, which caused the wandering nomadic kin group to transition into a permanently settled social group or village. However, new genetic evidence from a Neolithic graveyard in Derenberg, Germany in a study conducted by the University of Adelaide reveals otherwise. Genetic affiliations suggest these cultural innovators were “invaders with revolutionary new ideas, rather than populations of Stone Age hunter-gatherers who already existed in the area’”. Specifically, these invaders came from the Ancient Near East, where farming was practiced as early as 11,000 years ago, 3,000 years prior to its appearance in Europe. Similar to the way geneticists were able to utilize hominid DNA to construct migration routes from Africa to other continents, Adelaide researchers used genetic signatures to trace a potential migration route of the first farmer “invaders” from Anatolia and Hungary to Central Europe.

Mwah How well do you remember your first kiss? Looking back on it now, I would have never figured that that small act of kissing actually had a whole science behind it. Helen Fisher, a Biological Anthropologist from Rutgers University, states that, “kissing is a mechanism for mate choice and mate assessment.” Saliva is a Long Island ice tea of elements, meaning that our saliva contains plenty of hormones in different quantities that get transferred during a kiss. Interestingly enough, Fisher also states that there is evidence that saliva has testosterone in it, and that men prefer to have sloppier kisses. That indicates that unconsciously men are probably trying to transfer as much testosterone in order to set off a woman’s sex drive. Chemistry! Well, humans are not the only ones taking part in this act; animals are also locking lips, trunks, or beaks. Animals that have been spotted in the act are chimps, dogs, squirrels, cows, polar bears, foxes, birds, and even elephants putting their trunks in each others mouths.
Also take a look at these interesting facts from match.com:
1. Two out of every three couples turn their heads to the right when they kiss.
2. A simple peck uses two muscles; a passionate kiss, on the other hand, uses all 34 muscles in your face. Now that’s a rigorous workout!
3. Like fingerprints or snowflakes, no two lip impressions are alike.
4. Kissing is good for what ails you. Research shows that the act of smooching improves our skin, helps circulation, prevents tooth decay, and can even relieve headaches.
5. The average person spends 336 hours of his or her life kissing.
6. Ever wonder how an “X” came to represent a kiss? Starting in the Middle Ages, people who could not read used an X as a signature. They would kiss this mark as a sign of sincerity. Eventually, the X came to represent the kiss itself.
7. Talk about a rush! Kissing releases the same neurotransmitters in our brains as parachuting, bungee jumping, and running.
8. The average woman kisses 29 men before she gets married.
9. Men who kiss their partners before leaving for work average higher incomes than those who don’t.
10. The longest kiss in movie history was between Jane Wyman and Regis Tommey in the 1941 film, You’re in the Army Now. It lasted 3 minutes and 5 seconds. So if you’ve beaten that record, it’s time to celebrate!
