Did you know that ... clownfishes adults live in pairs associated with an anemone?

Posted: 28 Sep 2012 02:29 AM PDT

Did you know that to protect the eggs from the tentacles of the anemone, the clownfish takes the eggs one by one on its mouth and then rubs them on the tentacles and the mucus on the tentacles covers the eggs and immunises the embryos against the stinging substance?

The clownfish (Amphiprion ocellaris) is no more than 8 cm long and is distributed throughout the tropical western Pacific, in coastal reef areas and at depths ranging from 1 to 15 meters.

Adults live in pairs associated with an anemone. During the spawning season the female deposits 500 to 1500 eggs, which are fertilized and guarded by the male. They are deposited on a hard substrate, next to the anemone and within reach of their tentacles. With the continued movement of its fins, the male moves the water around the eggs to keep the developing embryos oxygenated and prevent fungus.

To protect the eggs from the tentacles of the anemone, the clownfish takes the eggs one by one on its mouth and rubs them on the tentacles. The mucus on the tentacles covers the eggs and immunises the embryos against the stinging substance.

The Hemisfèric starts new season of 'The Universe in your classroom' next 18th October

Posted: 27 Sep 2012 03:18 AM PDT

The Hemisferic will be dealing starts its new programme for students next 18th October.  At the Hemisfèric we have found the way for your students to learn what a galaxy or a planet is: taking a trip around them. Or none other than watching an eclipse of the sun live, to later move into Saturn’s rings. We also have keys to try and answer the question about whether or not we are alone in the universe. How? Thanks to the power and versatility of the digital planetarium.

A trip around the solar system and Our home in the cosmos are tailor made sessions in accordance with the profile and level of your students, where we combine varied, attractive contents with truly spectacular graphic resources. The best way of introducing your class to the fascinating world of astronomy.

The Universe in your classroom

The Science Museum invites you on an 'animal' tour to learn about science

Posted: 26 Sep 2012 09:39 PM PDT

The Science Museum invites its visitors on an ‘animal’ tour to see the living creatures included in its various displays designed to educate the public about science. Reptiles, insects and even microscopic creatures are all there to give visitors a better understanding of biology, evolution and adaptation to the natural environment.

All kinds of living things can be seen at the Museum, from a weird and wonderful giant egg-shaped cell to microscopic organisms. In 'Welcome to Life' there is a chick incubator where every day, lots of little chicks hatch. The cold-blooded animals can teach us what temperature is. A friendly bearded dragon, who is an expert in camouflage techniques, shows the audience how he remains unseen even to a heat-detecting camera, in the “Red Hot” workshop in Science on Stage. And in the “Micrarium” workshop, also in Science on Stage, one can see microscopic living organisms with incredible shapes whose entire habitat is encompassed in a single drop of water.

Underground corridors

If one wants to see great engineering projects, one only has to visit the ants’ nest to admire the amazing underground corridors built by the Atta, or leaf-cutter, ants. The display shows a recreation of their habitat, with water terrariums where one can watch the ants on semi-flooded islands that are linked by twigs. In the water itself, there are little fishes and tropical plants.

In the underground passageways, one can see how the ants grow a fungus and all the other subterranean activities of this species of large ant, whose queens measure up to 2.5 cm in length. They have had this relationship with the fungus for 60 million years, so one might say that they are the first farmers in history.

Here we can learn what characterises an insect or what differentiates insects from similar creatures such as termites. In the exhibition entitled “Furnishing the habitat. Hand in hand with nature” the visitor will find a real termite’s nest and understand how important these creatures are for maintaining the cycle of life, as they carry bacteria that decompose the cellulose in dead and dying trees.

Animals are the best way to understand evolution and how they adapt to the specific conditions found in their environment. In the “Forest of Chromosomes” exhibition on the third floor there are fascinating examples of this.

The skulls of giraffes (much larger than one might imagine, given that we always see them at a distance of several metres, at the top of their long, svelte owners), of hippopotami, elephants, tigers and even crocodiles tell us how different types of teeth are adapted to the type of food. The amazing aquatic salamander or ajolote (meaning “water dog”) is another case in point. It’s a very unusual amphibian which has remained in a permanent larval state.

And for the really curious, there is a gallery of curiosities: animals with malformations such as a three-legged hen, a one-eyed dog, a two-bodied lamb. They are all examples of what can happen when a certain gene doesn’t do its job properly.

Did you know that...today marks 107 years of the birth of Nobel Prize Severo Ochoa?

Posted: 24 Sep 2012 01:00 AM PDT

On September 24, 1905 was born in the town of Luarca (Asturias) Spanish biochemist Severo Ochoa de Albornoz, Nobel Prize in Physiology and Medicine. This award was won in 1959 together with his disciple Arthur Kornberg for their discovery of the mechanisms in the biological synthesis of ribonucleic acid (RNA) and deoxyribonucleic acid (DNA), the basis for modern research in molecular biology and cancer studies.

Ochoa studied medicine in Madrid and he completed his PhD in 1929. Two years later he married Carmen García Cobián. In 1933 he traveled abroad for the first time, particularly to universities of Heidelberg (Germany), and Glasgow (Britain), in order to further his studies. Later, return to Madrid, but not for long time, since the outbreak of the Spanish Civil War, in 1936, he left Spain again to continue his research in Germany, Britain and the United States, where he acquired with his wife U.S. citizenship 1956. During those years, he carried out research on pharmacology and biochemistry which earned him the prestigious medal Bewberg in 1951.

In 1955 he published, together with French-Russian biochemistry Marianne Grunberg-Manago, isolating of collibacilluses enzyme that catalyzes the RNA synthesis, the intermediary between DNA and protein, known as the enzyme RNA polymerase. In 1956, the American Arthur Kornberg showed that DNA synthesized also by the polymerase. Both findings represented a huge progress because now we could be done the decoding of the genetic code through statistical analysis of frequencies as other codes and unfamiliar languages are decoded. Severo Ochoa died in Madrid in November 1993.

'The Legacy of Science'

The second floor of the Museum houses a permanent exhibition, 'The Legacy of Science', which pays tribute to Professor Severo Ochoa, together with two Nobel Prizes, the Spanish Santiago Ramon y Cajal, and Frenchman Jean Dausset.

Of these, it takes a chronological journey, showing his life and the evolution of their research.

The Asturian scientific legacy consists of diplomas, appointments, plaques, medals, representative objects and awarded honors, including the Nobel Prize medal, besides private letters, scientific reports, lab notebooks and working notes, books, photographs, audiovisual documents, numerous autographs papers on various scientific topics and even the clothing used in their endowments as Doctor Honoris Causa in over 40 Spanish and foreign universities as Salamanca, Granada, Oviedo, Oxford, Brazil or Michigan.

La Ciudad de las Artes y las Ciencias participa en la semana solidaria a favor de UNICEF

Posted: 20 Sep 2012 04:12 PM PDT

La Ciudad de las Artes y las Ciencias colabora este sábado y domingo en la semana solidaria, organizada por el Club Náutico de Valencia a favor de UNICEF. Coincidiendo con la celebración del Trofeo Valencia de vela infantil, durante este fin de semana, de 10 a 14 horas se desarrollarán diversas actividades abiertas a todo el público.

Además de un castillo hinchable, cuya recaudación se donará a UNICEF, y descuentos en el Pase Anual de la Ciudad de las Artes y las Ciencias, el domingo, 23 de septiembre el público que se acerque a la Base de Regatas del Club Náutico tendrá la oportunidad de participar en diferentes propuestas relacionadas con el mundo marino puestas en marcha por el Oceanogràfic.

El visitante encontrará diversos stands donde manipular diferentes muestras biológicas y averiguar a qué animal pertenecen; aprender cómo se monta un equipo de buceo o conocer las principales amenazas que actualmente ponen en peligro la vida de las tortugas marinas.

El domingo concluirá con la reintroducción en el mar de una tortuga boba que ha sido recuperada en las instalaciones del ARCA del Mar del Oceanogràfic. Esta suelta, realizada en colaboración con la Conselleria de Infraestructuras, Territorio y Medio Ambiente, la llevarán a cabo los niños de la escuela de vela del Náutico que liberarán a la tortuga desde sus embarcaciones.

Did you know that...the day and night length is the same when autumn begins ?

Posted: 20 Sep 2012 01:24 AM PDT

On Saturday, September 22, at 4.49pm, there will be the change of season and therefore will start the fall that lasts 89 days and 20 hours. However, as usually twice a year, in October 28 we have to change the time. In this case, and in order to make up winter time we will delay time one hour at 3:00 a.m., which will be 2:00 am

In autumn equinox, as in the spring, the day and night length is the same due to the Earth's axis is positioned so its two poles are at the same distance from the Sun. At that moment solar center is in the same plane of Earth Ecuador and days and nights have similar duration.

Concerning astronomical phenomena, November 13 there will be a solar eclipse while November 28 will be given a penumbral lunar eclipse that will be visible in Spain. In particular, a slight darkening in the upper region of the lunar disc will appreciate.

On the other hand, the solar eclipse will be seen only in Australia, New Zealand, South Pacific, Antarctica and southern South America, according to the National Astronomical Observatory.

'The Universe in your classroom'

Starting on October 18 and until May 30, 2013 the Hemisfèric of the City of Arts and Sciences offers students the opportunity to observe this phenomenon in the digital planetarium sessions live 'The Universe in your classroom'.

In the Hemisferic’s projection hall elementary students will attend a live solar eclipse, and will learn what a galaxy or a planet is, among other curiosities. On their behalf the secondaru and high school students will know what a supernova is, how stars are formed or where are the exoplanets.

The Science Museum offers today a conference on ancient monuments linked related to astronomy

Posted: 19 Sep 2012 03:17 AM PDT

El Museo de las Ciencias ofrece hoy jueves, 20 de septiembre una conferencia en torno a los monumentos antiguos ligados a la astronomía impartida por Clive Ruggles, de la Universidad de Leicester y uno de los mayores expertos internacionales en arqueoastronomía. La charla ‘Monumentos ligados al cielo: la astronomía antigua y su patrimonio mundial’, de libre acceso y con la colaboración del British Council, se celebrará a partir de las 19:30 horas en el Auditorio Santiago Grisolía.

Algunos de los restos arqueológicos que nos ha dejado la historia constituyen un claro ejemplo de la influencia que ejercieron los fenómenos astronómicos sobre las civilizaciones del pasado. Desde las pirámides de Egipto hasta los antiguos observatorios solares, pasando por los dólmenes neolíticos de la península ibérica. Del interés por el estudio sobre el papel relevante que ha representado la astronomía en la cultura de los pueblos, desde cualquier punto de vista, surge la Arqueoastronomía.

“Cada cultura humana tiene su cielo. Desde tiempos inmemoriales, las comunidades humanas han luchado por interpretar lo que han visto allí y por entender su propio lugar en relación con el mundo. Los monumentos astronómicamente relacionados -desde los antiguos templos y tumbas hasta los modernos observatorios- son testigos de la extraordinaria diversidad de modos en los cuales nuestras especies han llegado a entender las relaciones entre ellos mismos y el mundo -el universo- en el que habitan”, explica Clive Ruggles, experto en arqueoastronomía.

Esta disciplina aborda el estudio de las orientaciones de ciertos monumentos tratando de ver su posible relación con los astros. Así, en España, un estudio sistemático de las orientaciones de un grupo característico y distintivo de dólmenes neolíticos -los ‘antas de 7 piedras’ que se encuentran en Extremadura y en la vecina región de Alentejo en Portugal- ha revelado que son las tumbas prehistóricas más antiguas conocidas con una asociación inequívoca con el sol.

Según indica este investigador, “la evidencia es estadísticamente abrumadora: las 177 tumbas medibles, sin excepción alguna, están orientadas hacia una posición del horizonte dentro del arco de la salida del sol; en otras palabras, donde el sol saldrá en algunos días determinados durante el año”.

Otros descubrimientos importantes que se han realizado en los últimos años son los observatorios solares de Taosi, en China, o el de Chankillo, en Perú, con más de dos mil años de antigüedad. En este país sudamericano, concretamente en los alrededores de Nazca, Clives Ruggles, ha finalizado recientemente un proyecto sobre el estudio de los ‘geoglifos’, un trabajo que se suma a otros, como el que ha llevado a cabo junto el arqueólogo polinesio Patrick Kirch en Hawai, basado en el estudio de las orientaciones y significado astronómico de los emplazamientos de los templos en las zonas de cultivo de secano de las islas orientales (Maui y la gran isla de Hawai) en los siglos anteriores a su contacto con los europeos.

DID YOU KNOW THAT...? On this day in 1819 was born in Paris Leon Foucault, father of the pendulum that demonstrated the Earth's rotation

Posted: 18 Sep 2012 12:58 AM PDT

'You are invited to see the earth turn ... "this shocking announcement shoocked Parisian society in 1851. At the pantheon in Paris: Leon Foucault with a cable of 67 meters and a cannonball of 28 kilos, demonstrated the rotation of the earth, 220 years after Galileo. On September 18, in 1819 was born the great french physicist Jean Bernard Leon Foucault, father of the pendulum which served to demonstrate the rotation of the earth and that Galileo was right.

Foucault's Pendulum in the Science Museum

In the First Floor of the Science Museum, a pendulum hanging from the very top of the building’s eaves, with a circular base of moving parts, sets out to demonstrate that the earth rotates around its own axis.

With a longitude of 34 metres, the pendulum is one of the longest in the world; its complete cycle of revolution is approx. 34 hours. In reality, the pendulum is not spinning because it is the Earth itself, and with it, the entire Museum.

Did you know that today marks the 36TH anniversary of the space shuttle Enterprise?

Posted: 17 Sep 2012 03:09 AM PDT

Since 2002, more than 220,000 visitors have 'traveled' to the International Space Station in the Science Museum thanks to the interactive module 'Space Academy'. It is an opportunity to see how it might be your first experience as an astronaut, a prototype ship for space missions as was once the Enterprise, which today turns 36 years since its commissioning.

As astronauts in the Science Museum

Space Academy recreates through the movement simulation three stages in the preparation for the space launching until the International Space Station. Guided by the voice and the image of the Spanish astronaut Pedro Duque, visitors cross the space laboratory, the launching elevator and the airlift that allows the access to the space flight simulator.

The trip is made by groups of eight people and lasts about thirty minutes. The price is 2,05 € per session for general public.
