Sweetness is one of the five basic tastes and is universally regarded as a pleasurable experience, except perhaps in excess. Foods rich in simple carbohydrates such as sugar are those most commonly associated with sweetness, although there are other natural and artificial compounds that are sweet at much lower concentrations, allowing their use as non-caloric sugar substitutes. Examples of foods that may be used as non-sugar sweet substitutes include saccharin, aspartame, acesulfame potassium, sucralose, xylitol, erythritol, and stevia. Other compounds, such as miraculin, may alter perception of sweetness itself.
The chemosensory basis for detecting sweetness, which varies between both individuals and species, has only begun to be understood since the late 20th century. One theoretical model of sweetness is the multipoint attachment theory, which involves multiple binding sites between a sweetness receptor and a sweet substance.

Crash Course (also known as Driving Academy) is a 1988 made for television teen film directed by Oz Scott.
Crash Course centers on a group of high schoolers in a driver’s education class; many for the second or third time. The recently divorced teacher, super-passive Larry Pearl, is on thin ice with the football fanatic principal, Principal Paulson, who is being pressured by the district superintendent to raise driver’s education completion rates or lose his coveted football program. With this in mind, Principal Paulson and his assistant, with a secret desire for his job, Abner Frasier, hire an outside driver’s education instructor with a very tough reputation, Edna Savage, aka E.W. Savage, who quickly takes control of the class.
The plot focuses mostly on the students and their interactions with their teachers and each other. In the beginning, Rico is the loner with just a few friends, Chadley is the bookish nerd with few friends who longs to be cool and also longs to be a part of Vanessa’s life who is the young, friendly and attractive girl who had to fake her mother’s signature on her driver’s education permission slip. Kichi is the hip-hop Asian kid who often raps what he has to say and constantly flirts with Maria, the rich foreign girl who thinks that the right-of-way on the roadways always goes to (insert awesomely fake foreign Latino accent) “my father’s limo”. Finally you have stereotypical football meathead J.J., who needs to pass his English exam to keep his eligibility and constantly asks out and gets rejected by Alice, the tomboy whose father owns “Santini & Son” Concrete Company. Alice is portrayed as being the “son” her father wanted.
Khan Academy is a non-profit educational organization created in 2006 by educator Salman Khan with the aim of providing a free, world-class education for anyone, anywhere. The organization produces short lectures in the form of YouTube videos. In addition to micro lectures, the organization's website features practice exercises and tools for educators. All resources are available for free to anyone around the world. The main language of the website is English, but the content is also available in other languages.
The founder of the organization, Salman Khan, was born in New Orleans, Louisiana, United States to immigrant parents from Bangladesh and India. After earning three degrees from the Massachusetts Institute of Technology (a BS in mathematics, a BS in electrical engineering and computer science, and an MEng in electrical engineering and computer science), he pursued an MBA from Harvard Business School.
In late 2004, Khan began tutoring his cousin Nadia who needed help with math using Yahoo!'s Doodle notepad.When other relatives and friends sought similar help, he decided that it would be more practical to distribute the tutorials on YouTube. The videos' popularity and the testimonials of appreciative students prompted Khan to quit his job in finance as a hedge fund analyst at Connective Capital Management in 2009, and focus on the tutorials (then released under the moniker "Khan Academy") full-time.
Sweet'n Low (stylized as Sweet'N Low) is a brand of artificial sweetener made primarily from granulated saccharin. It also contains dextrose and cream of tartar, and is distributed primarily in packets.
Sweet'n Low is manufactured and distributed in the United States by Cumberland Packing Corporation, which also produces Sugar in the Raw and Stevia in the Raw, and in the United Kingdom by Dietary Foods Ltd. Its patent is U.S. Patent 3,625,711. The trademark of words "Sweet'n Low" and the musical staff logo is U.S. Trademark registration No. 1,000,000.
In Canada, Sweet 'n Low is made from sodium cyclamate instead of saccharin. This is because saccharin was not allowed as a food additive in Canada, beginning in 1977, when studies surfaced showing cancer resulting in laboratory rats that had been administered the additive. In 2014, Canada lifted this ban since the studies were recently proven faulty, and several other countries have lifted their saccharin bans and warnings as well.

Taste molecules interact with taste receptor cells on the mammalian tongue. Taste processing is segregated by taste quality, such that each taste cell responds to one of the 5 taste qualities--sweet, salty, sour, bitter, or umami.

Hank resists the urge to devour a slice of pizza so that he can walk you through the way we experience our major special senses. It all boils down to one thing: sensory cells translating chemical, electromagnetic, and mechanical stimuli into action potentials that our nervous system can make sense of. Today we're focusing on smell (olfaction) and taste (gustation), which are chemical senses that call on chemoreceptors. As usual, we'll begin with a quick look at how these things can go wrong.

In collaboration with Carry The One Radio, we have produced a short video explaining why cats cannot taste sweet foods. Learn what cats and dolphins have in common that makes them fundamentally different from humans.
You know how babies put everything in their mouth? They’re actually exploring with taste! Thanks to our gustatory system, we can detect millions of distinct tastes through combinations of our different taste receptors, kind of like how colors are a combination of different visual receptors. It brings enjoyment to our lives and, most likely, kept our ancient ancestors from chowing down on poisonous foods. Come learn the neuroscience of taste with Alie Astrocyte.

Do cats prefer sardines or sweets? Our newest video explains why cats, unlike humans and other mammals, are indifferent to sweet flavors. The video was filmed at the Monell Chemical Senses Center, an institute dedicated to research on taste and smell. Prior to becoming Monell's Director, Gary Beauchamp studied the sweet taste receptor genes of cats in the late 1970s. At the Philadelphia Zoo, he gave lions, tigers, cheetahs and housecats two different types of water—sugar water and regular water. The cats showed no preference to the sugar water, suggesting a physiological difference between other mammals, such as humans, monkeys, and dogs. Watch the video to find out the cause of your cat's missing sweet tooth. Produced by the American Chemical Society Directed and animated by Elaine ...
EmpoweRN.com For more ARBS NCLEX questions, go here: http://empowern.com/2015/06/arbs/ ARBs are a relatively new type of antihypertensive drugs, which were developed to cover the shortcomings of ACE inhibitors. For instance, for patients who are sensitive to the side effects of ACE inhibitors, the treatment can be done using ARB drugs instead of ACE inhibitors. Mechanism of action: Human body contains several mechanisms which help protect it against severe conditions. Renin-angiotensin-aldosterone system (RAAS) is one of those mechanisms. When blood pressure decreases due to blood loss or other reasons, RAAS is activated to reverse the reaction and prevent cardiovascular collapse. However, prolonged or inappropriate activity of RAAS can lead to hypertension, which can damage vital or...

What are artificial sweeteners made of? There are five FDA-approved artificial sweeteners, and each of them has a different chemical makeup. There's sucralose (Splenda), acesulfame potassium (Sunett, Sweet One), aspartame (Equal, NutraSweet), neotame, and saccharin (SugarTwin, Sweet'N Low). Aspartame, the sweetener most often used in diet sodas, for instance, is composed of two amino acids: aspartic acid and phenylalanine, according to the American Cancer Society. Splenda, on the other hand, is created by replacing hydrogen and oxygen in sugar molecules with chlorine atoms. "It's a taste issue," says Barry Popkin, professor of nutrition at the University of North Carolina's Gillings School of Public Health. "They each have separate taste effects and different people react differently to ea...

I'd like to introduce another producer new to the Vocalectro scene named "Kew". READ FOR MORE ↓↓↓ This is the first Vocaloid work from the producer named "Kew". He is by no means new to composing music, however. He is surprisingly the the elder/mentor of Osanzi! That certainly explains a lot. He's been learning from someone who's clearly highly skilled in electronic music. The use of Hatsune Miku's Dark Append and masterful composition made this a truly excellent track worthy of more recognition, and I'm glad that Kew has allowed me to share it! Osanzi also helped Kew with rendering an HD version for you guys to enjoy, so those two deserve special thanks for that. Kew provides this track for free download on Nicovideo in M4A, and from the Soundcloud description in lossless WAV. Be sure ...
