Formed in 1991 in Northampton , Massachusetts , it comprised Joe Pernice , Stephen Desaulniers , Bruce Tull and Tom Shea . Stephen Desaulniers left the band and was replaced by Frank Padellaro in October 1996 . The band at first was known as the Scuds , and their early work was influenced by electric rock . However , they sat round Tull 's kitchen table every night and played acoustic country tunes , and soon decided that they enjoyed this style more . This culminated in the Scud Mountain Boys bringing the table to a concert and playing while sitting down , a move which was enthusiastically welcomed . The band released three albums before disbanding in 1997 : Dance the Night Away ( 1995 ) , Pine Box ( 1995 ) and Massachusetts ( 1996 ) . Pernice , Shea and Desaulniers reunited for an impromptu performance in Cambridge in August 2011 . The band announced plans for a full reunion of the original lineup in January 2012 and social networking sites confirmed involvement of Pernice , Desaulniers , Tull and Shea for the shows . The band 's fourth album , Do You Love the Sun was released in 2013 . The Early Year , a compilation of their first two albums Dance the Night Away and Pine Box , was also released that year . Pernice , the group 's main songwriter , later went on to form the more pop / rock - influenced band Pernice Brothers . - Indie rock is a genre of alternative rock that originated in the United States and the United Kingdom in the 1980s. Indie rock encapsulates indie pop and lo-fi, among others. Originally used to describe record labels, the term became associated with the music they produced and was initially used interchangeably with alternative rock. As grunge and punk revival bands in the US, and then Britpop bands in the UK, broke into the mainstream in the 1990s, it came to be used to identify those acts that retained an outsider and underground perspective. In the 2000s, as a result of changes in the music industry and the growing importance of the Internet, some indie rock acts began to enjoy commercial success, leading to questions about its meaningfulness as a term. - A writer is a person who uses written words in various styles and techniques to communicate their ideas. Writers produce various forms of literary art and creative writing such as novels, short stories, poetry, plays, screenplays, and essays as well as various reports and news articles that may be of interest to the public. Writers' texts are published across a range of media. Skilled writers who are able to use language to express ideas well often contribute significantly to the cultural content of a society. The word is also used elsewhere in the arts such as songwriter but as a standalone term, "writer" normally refers to the creation of written language. Some writers work from an oral tradition. - A county seat is an administrative center, seat of government, or capital city of a county or civil parish. The term is used in the United States, Canada, Romania, China and Taiwan. In the United Kingdom and Ireland, county towns have a similar function.

[Q]: Information: - The Universe is all of time and space and its contents. It includes planets, moons, minor planets, stars, galaxies, the contents of intergalactic space, and all matter and energy. The size of the entire Universe is unknown. - A laboratory (CommE or , AmE ; informally, lab) is a facility that provides controlled conditions in which scientific or technological research, experiments, and measurement may be performed. - In chemical synthesis , '' click '' chemistry is a class of biocompatible reactions intended primarily to join substrates of choice with specific biomolecules . Click chemistry is not a single specific reaction , but describes a way of generating products that follows examples in nature , which also generates substances by joining small modular units . In general , click reactions usually join a biomolecule and a reporter molecule . Click chemistry is not limited to biological conditions : the concept of a '' click '' reaction has been used in pharmacological and various biomimetic applications . However , they have been made notably useful in the detection , localization and qualification of biomolecules . Click reactions occur in one pot , are not disturbed by water , generate minimal and inoffensive byproducts , and are '' spring - loaded '' -- characterized by a high thermodynamic driving force that drives it quickly and irreversibly to high yield of a single reaction product , with high reaction specificity ( in some cases , with both regio - and stereo - specificity ) . These qualities make click reactions particularly suitable to the problem of isolating and targeting molecules in complex biological environments . In such environments , products accordingly need to be physiologically stable and any byproducts need to be non-toxic ( for in vivo systems ) . By developing specific and controllable bioorthogonal reactions , scientists have opened up the possibility of hitting particular targets in complex cell lysates . Recently , scientists have adapted click chemistry for use in live cells , for example using small molecule probes that find and attach to their targets by click reactions . Despite challenges of cell permeability , bioorthogonality , background labeling , and reaction efficiency , click reactions have already proven useful in a new generation of pulldown experiments ( in which particular targets can be isolated using , for instance , reporter molecules which bind to a certain column ) ,... - A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Classically, chemical reactions encompass changes that only involve the positions of electrons in the forming and breaking of chemical bonds between atoms, with no change to the nuclei (no change to the elements present), and can often be described by a chemical equation. Nuclear chemistry is a sub-discipline of chemistry that involves the chemical reactions of unstable and radioactive elements where both electronic and nuclear changes may occur. - Chemical synthesis is a purposeful execution of chemical reactions to obtain a product, or several products. This happens by physical and chemical manipulations usually involving one or more reactions. In modern laboratory usage, this tends to imply that the process is reproducible, reliable, and established to work in multiple laboratories. - Nature, in the broadest sense, is the natural, physical, or material world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena.
