El Hemisfèric celebra el lunes 16 de abril su catorce aniversario con entradas a 3,5 euros Posted: 01 Apr 2012 05:23 PM PDT El Hemisfèric cumple el próximo lunes, 16 de abril,  catorce años desde su apertura en 1998. Para celebrarlo, ese día la Ciudad de las Artes y las Ciencias ofrecerá las entradas para las producciones IMAX y 3D, a un precio de 3,5 euros. De este modo, el público que se acerque el próximo 16 de abril hasta el Hemisfèric podrá disfrutar con esta tarifa reducida de producciones como la que presenta los gigantes prehistóricos que surcaban el aire hace 220 millones de años, la película sobre el telescopio Hubble o sobre cómo la entrega de determinadas personas salva especies amenazadas, entre otras. El Hemisfèric fue el primero de los elementos puestos en marcha en el complejo de divulgación y desde su apertura, cerca de 7 millones de espectadores han disfrutado de más de 47 producciones que suman más de 40.000 horas de proyección relacionados con la ciencia, las nuevas tecnologías o la naturaleza. Nuevas películas en mayo Asimismo, el próximo 13 de mayo, el Hemisfèric estrenará en España, ‘Tortugas 3D’ y ‘El Principito 3D’, dos animaciones infantiles en versión 3D que se proyectarán en una misma sesión. Con estos títulos, la Ciudad de las Artes y las Ciencias, junto con nWave Pictures, acercan al público del Hemisfèric las aventuras de Sammy, una tortuga que viaja alrededor del mundo, y el clásico de Antoine de Saint-Exupéry que el próximo 6 de abril cumple 69 años desde su publicación en 1943

Did you know... that in April 1953 the discovery of the structure of DNA was announced? Posted: 02 Apr 2012 01:37 AM PDT In April 1953, Francis Crick and James Watson announced their discovery of the structure of deoxyribonucleic acid (DNA). In a short, one and half paged article published in the Nature journal, Watson and Crick changed the world as they suggested that DNA was structured as a double helix. According to Manuel Toharia, Science Director at the City of Arts and Sciences, “they achieved this with their own research work, and it earned them the Nobel Prize in 1962, alongside Maurice Wilkins from the UK, who had carried out previous work that helped them to complete the task”. Watch the video about 'Forest of chromosomes'. As Manuel Toharia recalls “in that previous work, a British colleague of Wilkins, the biophysicist and crystallographer Rosalind Franklin, had gone further than anyone else in establishing that DNA took the shape of a double helix. Apparently, Watson and Crick, through Wilkins, consulted Franklin’s work without her permission, which then put them in an advantageous position. Today, everyone believes that Franklin deserves as much or more recognition than the other three: in fact, she had already described the DNA molecule before Watson and Crick announced it. She never got the Nobel prize, although she deserved it more than anyone, because she died young, in 1958”. Genetic code is the universal language of life that describes how all organisms, from the simplest to the most complex, will develop, what they are like, how they work and how they reproduce. It is a language shared by all the living things that populate or have ever populated the planet. In the Science Museum’s “Forest of Chromosomes”, 23 pairs of giant chromosomes represent the human genome on a large scale. Each pair of chromosomes has an interactive module about their specific genes and how they work, as well as numerous information panels with explanations on Genetics and plant, animal and human life in general. Every organism carries its very own “instruction manual” that we call the genome. In each and every species, the genomes of each individual are slightly different. Every one of the cells in an organism contains a copy of this set of instructions. It’s like a vast library where the books (the genes) contain all the information the individual needs to take shape, be born, live and reproduce. These books, the text of which is written in the language of DNA, are on occasions (for example, when the cell is reproduced) stored in a set number of bookshelves: the chromosomes. A walk through the “Forest of Chromosomes” will reveal how much water makes up the body, what our chemical compounds are, what allows us to listen or where our blood goes when it leaves the heart. We can be amazed by the speed of a sneeze or the number of genes that differentiates us from a mouse. And we can learn that pain allows the palate to identify hot spices and why men are more likely to be colour-blind than women. One hundred and fifty interactive models are there to tell us about the genes and their functions in living things. “Our Forest of Chromosomes”, says Manuel Toharia, “is a homage to the history of the genome in general and to the chemical structure of DNA in particular. The sequencing of the human genome by Craig Venter (published in 2001, half a century after Watson and Crick’s announcement) was not, in actual fact, totally accurate or complete. Even today, in 2012, we do not know the exact number of human genes, but it is probably less than 25,000. But the first steps taken by genetic engineering show what the future holds, and it will be brilliant, in terms of compressing the fundamentals of life and how this is applied to medicine and many other human activities in the years ahead”. The guided visit to the “Forest of Chromosomes” also includes a workshop for secondary school students entitled “Extracting DNA”, in which this macromolecule is separated and one can find out about its composition, structure and properties and what this discovery means for the development of biological science. The Museum’s Calle Mayor also displays an artistic representation of DNA in the form of a spectacular, 15 metre tall sculpture.
