  Astrobiology - The Search for...

  Extraterrestrial life is a common theme in
  
  science fiction, but is it a serious prospect in the real world? Astrobiology
  
  is the emerging field of science that seeks to answer this question.
  
  The possibility of life elsewhere in the cosmos
  
  is one of the most profound subjects that human beings can ponder. Astrophysicist
  
  Andrew May gives an expert overview of our current state of knowledge, looking
  
  at how life started on Earth, the tell-tale 'signatures' it produces, and how
  
  such signatures might be detected elsewhere in the Solar System or on the many 'exoplanets'
  
  now being discovered by the Kepler and TESS missions.
  
  Along the way the book addresses key questions such as the riddle of Fermi's
  
  paradox ('Where is everybody?') and the crucial role of DNA and water – they're
  
  essential to 'life as we know it', but is the same true of alien life? And the really
  
  big question: when we eventually find extraterrestrials, will they be friendly
  
  or hostile?

  Chemistry studies the nature (atomic and molecular structure, etc.), properties, composition and transformations of matter. Here are some benefits that chemistry can provide: 
  ♦ fabrics of the clothes we use in day-to-day are materials obtained through the development of Chemistry;the artificial fibers (nylon, tergal, etc.), synthetic rubbers, plastics, part of a group of materials called polymers; polymers have been numerous applications: plastic bags, towels, bottles, plastic pipes, electrical coatings, toys, records, upholstery, pan coatings; 
  Biochemistry has allowed not only to know precise mechanisms of the body, such as influence them, enabling the development of molecular biology and pharmacology, fundamental to the progress of medicine. And in the area of ​​Food Engineering, for example, is that chemistry plays a significant role? Yes. It is vital! 
  For example, the food industry uses the so-called "additives": substances are capable of providing the following foods: - antioxidant (inhibits the oxidation process); - Preservatives (increase durability); - Stabilizers (helps keep emulsions and suspensions); - Sweeteners (transmits sweet taste to products), etc. Most countries have four types of artificial sweeteners found in the consumer market: - saccharin (Pan American) - the CYCLAMATE (Brasfanta) - the ACESULFAME-K (Hoechst) - aspartame (Monsanto). Obtaining these sweeteners requires well-established synthetic routes developed in research in the field of chemistry. To understand the metabolism of sweeteners in humans and investigate the toxicity mechanisms have been proposed that involve a series of chemical reactions (w / details, see ref. *). As can be seen, chemistry has provided numerous benefits to humanity. On the other hand, we can not forget that many chemical processes are responsible for the degradation of the environment in which we live.
