Piano

The piano (Italian pronunciation: [ˈpjaːno]; an abbreviation of pianoforte [pjanoˈfɔrte]) is a musical instrument played using a keyboard. It is widely employed in classical, jazz, traditional and popular music for solo and ensemble performances, accompaniment, and for composing and rehearsal. Although the piano is not portable and often expensive, its versatility and ubiquity have made it one of the world's most familiar musical instruments.

An acoustic piano usually has a protective wooden case surrounding the soundboard and metal strings, and a row of 88 black and white keys (52 white, 36 black). The strings are sounded when the keys are pressed, and silenced when the keys are released. The note can be sustained, even when the keys are released, by the use of pedals.

Pressing a key on the piano's keyboard causes a padded (often with felt) hammer to strike strings. The hammer rebounds, and the strings continue to vibrate at their resonant frequency. These vibrations are transmitted through a bridge to a soundboard that amplifies by more efficiently coupling the acoustic energy to the air. When the key is released, a damper stops the strings' vibration, ending the sound. Although an acoustic piano has strings, it is usually classified as a percussion instrument because the strings are struck rather than plucked (as with a harpsichord or spinet); in the Hornbostel-Sachs system of instrument classification, pianos are considered chordophones. With technological advances, electric, electronic, and digital pianos have also been developed.

Sweetness

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.

DNA

Deoxyribonucleic acid (ⁱ/diˈɒksiˌraɪboʊnjʊˌkliːɪk, -ˌkleɪɪk/;DNA) is a molecule that carries most of the genetic instructions used in the development, functioning and reproduction of all known living organisms and many viruses. DNA is a nucleic acid; alongside proteins and carbohydrates, nucleic acids compose the three major macromolecules essential for all known forms of life. Most DNA molecules consist of two biopolymer strands coiled around each other to form a double helix. The two DNA strands are known as polynucleotides since they are composed of simpler units called nucleotides. Each nucleotide is composed of a nitrogen-containing nucleobase—either cytosine (C), guanine (G), adenine (A), or thymine (T)—as well as a monosaccharide sugar called deoxyribose and a phosphate group. The nucleotides are joined to one another in a chain by covalent bonds between the sugar of one nucleotide and the phosphate of the next, resulting in an alternating sugar-phosphate backbone. According to base pairing rules (A with T, and C with G), hydrogen bonds bind the nitrogenous bases of the two separate polynucleotide strands to make double-stranded DNA. The total amount of related DNA base pairs on Earth is estimated at 5.0 x 10³⁷, and weighs 50 billion tonnes. In comparison, the total mass of the biosphere has been estimated to be as much as 4 TtC (trillion tons of carbon).

Little Mix

Little Mix are a British girl group formed in 2011, consisting of members Jade Thirlwall, Perrie Edwards, Leigh-Anne Pinnock, and Jesy Nelson. They were formed exclusively for the eighth series of The X Factor in 2011 and became the first, and so far, only group to win the competition. Following their victory, they signed with Simon Cowell's record label Syco Music and released a cover of Damien Rice's "Cannonball" as their winner's single.

Little Mix released their debut album DNA on 19 November 2012. It charted in the top 5 in eight countries, including number two in the UK and number four on the US Billboard 200. This made Little Mix the first girl group since The Pussycat Dolls to reach the U.S. top 5 with their debut album, as well as earning the highest debut U.S. chart position by a British girl group, breaking the record previously held by the Spice Girls, whose 1996 debut Spice debuted at number five. In 2015, they won Breakout Artist at the Teen Choice Awards in Los Angeles.
