Ramón y Cajal

Natalia Fernández Ferrer

Today I am going to speak a little about Santiago Ramón y Cajal. He was well-known by scientists and naturalists around the  world, thanks to  his experiments and especially for his investigations neuroscience.

Ramón y Cajal was born on the 1st of May of 1852 and died on October 17th, 1934. As a  child, he wanted to be a painter, but his father, teacher of Applied Anatomy, managed to persuade him to study medicine.

Finally,  Santiago become a Spanish doctor specialised in histology and pathological anatomy. He graduated in the University of Zaragoza in 1873, and practised for two years as a doctor. He took part in the war of Cuba where he contracted malaria and tuberculosis . He got his doctorate in Madrid in 1877.

His  work was focused on studying the histology of the nervous system. He was the one who discovered the theory of the neuron, according to which the nervous cells are individual and never form a diffuse reticulum, as many histologists were defending. He also discovered the direction of the nervous impulse. Thanks to all these experiments and discoveries he won the Nobel Prize in 1906 shared with Camilo Golgi.

The weight

Nicolás de la Madrid y de Vega

Mercury: A person of 100 kilos in the Earth, in Mercury it weights 38 kilos. This can be possible because de gravity of Mercury is a 38% from the Earth

Venus: A person of 100 kilos in the Earth, in Venus it weights 91 kilos. This can be possible because de gravity of Venus is a 91% from the Earth.  

Mars: A person of 100 kilos in the Earth, in Mars it weights 38 kilos. This can be possible because de gravity of Mars is a 38% from the Earth.

Jupiter: A person of 100 kilos in the Earth, in Jupiter it weights 214 kilos. This can be possible because de gravity of Jupiter is a 214% from the Earth.

Saturn: A person of 100 kilos in the Earth, in Saturn it weights 74  kilos. This can be possible because de gravity of Saturn is a 74% from the Earth.

Uranus: A person of 100 kilos in the Earth, in Uranus it weights 86 kilos. This can be possible because de gravity of Uranus is a 86% from the Earth.

Neptune: A person of 100 kilos in the Earth, in Neptune it weights 110 kilos. This can be possible because de gravity of Neptune is a 110 % from the Earth.

Pluto: A person of 100 kilos in the Earth, in Pluto it weights 8 kilos. This can be possible because de gravity of Pluto is a 8 % from the Earth.


Detectan por primera vez galaxias alimentadas por gas cósmico

Martín Pérez-Bernardo Villabrille

Este fenómeno ya había sido descubierto pero hasta el dia de hoy no se había podido observar. Unos astrónomos del Instituto de Canarias  detectan gracias al gran Telescopio del Observatorio del Roque distintas galaxias alimentándose del gas cósmico que , al parecer  es como una red.

Este raro acontecimiento surge debido a que las galaxias van creciendo y van creando estrellas necesitan un aportación extra de materia ya que dicha materia es bastante escasa o limitada para vivir. Los expertos aseguran que este gas es una red de filamentos que viaja a través del universo,  este gas primigenio fue producido por el Big Bang.

Este extraño gas está producido simplemente por hidrógeno y helio y que es muy raro en la galaxia.También se ha encontrado en las galaxias débiles gas contaminado debido a las estrellas de oxígeno o carbono.
