El robot, que ha sido destruido por una gran tormenta de polvo, llevaba 15 años estudiando la superficie del planeta rojo.

Discover liquid and salt water on Mars for the first time NASA finds organic molecules in Mars rocks of 3,000 million years.NASA has completed the mission of rover Opportunity on Mars on Wednesday after 15 years exploring the surface of the red planet. "For missions like this will come the day when astronauts can walk on Mars," said Jim Bridenstine, administrator of NASA.

The US agency has decided to end the mission after more than a thousand attempts to contact the robot, which was silenced due to lack of power on June 10 due to a sandstorm.

The exploration vehicle, powered by solar energy, was affected by the drastic reduction of the Sun's radiation by the suspended dust, limiting the capacity of its solar panels to charge the batteries that gave it the ability to move and to operate its Scientific instruments.

Text commentary:

This news does not contribute much to people like us but the workers of NASA have been hurt that this robot has died because that robot was providing information that for a future could not help in anything. In this information is not something that is very important for everyone and as more robots make them die one does not pass anything

Titular:Por qué no hemos conseguido acabar con el Alzhéimar

Resumen 

Según la Fundación Alzheimer España, cada año se diagnostican 100.000 nuevos casos y se prevé que en 2050 aumente mucho esa cifra.

Como hipótesis la principal causa sería primero por una acumulación de placas de proteínas amiloides en el cerebro, después con la aparición después de ovillos de otra proteína (tau) que destruyen las neuronas y por ultimo la inflamación que remata la catástrofe.

En Colombia hay esperanzas de encontrar un tratamiento con un fármaco llamado crenezumab. Un científico/investigador dice: “Como conocemos que la enfermedad tiene un origen genético y se da en determinadas familias y a partir de cierta edad, se cree que se puede dar el fármaco correcto en el momento correcto”

Tantos años buscando una cura a esta enfermedad ha hecho que el interés aumente y que las interpretaciones alternativas sobre el origen de esta aumenten.Estudios recientes han encontrado vínculos entre el alzhéimer e infecciones por hongos, por los virus del herpes o bacterias que causan infecciones de encías. Sin embargo, según explica José Luis Molinuevo, director del Barcelonaβeta Brain Research Center, el instituto de investigación de la Fundación Pasqual Maragall, “la realidad detrás de todo esto es que [el origen] el alzhéimer es sumamente complejo y su inicio se puede precipitar por diferentes situaciones y agentes de riesgo. No es descartable que el equilibrio que existe en el cerebro donde todos metabolizamos de forma normal la proteína precursora del amiloide se rompa, entre otros factores, por las infecciones”

En conclusión, de momento no hay un tratamiento que cure la enfermedad ni se conoce el origen de esta. Los científicos argumentan que la enfermedad tendría su origen hasta 20 años después de que se manifestaran los síntomas.

Ávila reconoce que los resultados de las últimas décadas no han sido tan buenos como les hubiera gustado a los investigadores, pero cree que el órgano afectado por la enfermedad la convierte en un reto mayor que, incluso, el cáncer.

Comentario

Bajo mi punto de vista, esta enfermedad es una sorpresa debido a ser un misterio para todos los investigadores y científicos. Creo que nunca se sabrá el origen de esta ya que han pesado muchos años y no se ha encontrado ninguna explicación oficial al origen, respecto a la cura de la enfermedad opino que habrá un tratamiento, pero no curara del todo la enfermedad, sino que hará que el proceso sea mas lento.

Glosario:

Amiloidosis:es una enfermedad poco frecuente que se produce cuando una sustancia llamada «amiloide» se acumula en los órganos. El amiloide es una proteína anormal que se produce en la médula ósea y puede depositarse en cualquier tejido u órgano.

Commentary:

We should take care about what we eat and drink. I recommend and i think its a good advice that all of us look at the labels of the ingredients of the products. So we can notice all the thins that is added to certain food products. About this lemon case there are many more that happened actually and we don’t know.

On the other hand, we have the people who create or do this lemon juice that don’t put in the label this and is a serious problem, because someone could have suffered vomiting (for example) as it puts in the summary.

Personalized medicine reaches childhood cancer

Vall d'Hebron sequences the genome of pediatric tumors with poor prognosis to find new therapeutic targets and apply targeted treatment

Itzal was five years old when he was diagnosed with bladder rhabdomyosarcoma, a very aggressive tumor that required very powerful chemotherapy and mutilating surgery. The little girl started the treatment and endured, for a month, the aftermath of those pills that forced her to take: she vomited, her hair fell and her defenses were so low she could barely approach her little sister, because of the risk that I passed on some pathogen. One month he was with this chemotherapy until at the Vall d'Hebron hospital in Barcelona, ​​reference center in Spain for sarcomas, they sequenced the genome of his tumor and discovered that, in reality, that mass in the bladder was an inflammatory myofibroblastic cancer, a tumor that is locally aggressive but does not metastasize. The analysis revealed that in his genetic instruction book there was a failure that made the tumor sensitive to a treatment that was much less aggressive than the chemo he had received. In a few months, the girl responded to that drug and the intervention to remove the tumor was minimally invasive and without sequelae. The genetic analysis of his tumor gave a twist to his prognosis and found something extra widespread in adult oncology: precision personalized medicine saves lives.


COMENTARI DEL TEXT:I think it's really good that you get better at cancer, which is a very common disease, and it's getting easier to get out of it thanks to advances in medicine, I hope it keeps improving and progressing so that every time this and any disease, not may cause death,It is also interesting that in Spain are the best cures for cancer I like that we are desenvolupados in this area.
