Why Mars lose his atmosphere? And thoughts political of Unamuno

 16/02/2018

Santiago Pérez Hoyos repass studies that analyze  the efects of the weak gravity and the radiation solar in Mars. The hispanita Jean Claude Rabaté investigates the last acts of Unhumano in 1936.

Two news investigations analyze the factors that have influenced the loss of the Martian atmosphere. The absence of magnetic field on this planet, the weak gravity and exposoure to solar radiation are possible reasons for its loss of atmosphere. This has done that Mars become in a plantet in one desert arid and cold. Also it's previse one future colision between the Via Lactea and Andromeda in 5000 milions of years thing that does not bother us much.

This analyze its do for a lots of experts thing that give we more security that is true besides of that problem will be a problem to Mars because will do one change of temperatures in this planet quite more bestial.

Glossary:

The problem of the lose the amosphere in Mars and the colision between the Via Lactea and Andromeda.
  

Text comentary:

This thing in my opinion it is a very bad problem to Mars because that provoques a vare bestial change of temperature in Mars.

DISCOVER IN THE SPERMATOZOIDS

A SPIRAL NEVER SEEN
It is located in the tail, and its function remains a mystery

22/02/2018

http://www.quo.es/ciencia/espermatozoides

Researchers from the Department of Chemistry and Molecular Biology

at the University of Gothenburg(Sweden) had discovered a strange

structure in the form of helix or spiral that spermatozoon have in their

tail, which had never been observed.

The tail of the sperm is formed by thousands of small blocks of protein

called tubulins, which form larger structures in the form of tubes called

microtubules. In this microtubules is where the spiral had been discovered.

It is suspected that they can act as a barrier to prevent tubulins from

developing abnormally, preventing the sperm from swimming.

Scientific field: Biology

Glossary:

-tubulins:in molecular biology can refer either to the tubulin

protein superfamily of globular proteins, or one of the member proteins of that

superfamily.

-spermatozoon:a motile male gamete of an animal usually

with rounded or elongated head and a long posterior flagellum.

Text comment

It is necessary to study these helices with caution since they perform the

function that is suspected could be something vital for the survival of

some living beings.

→ Glossary:

- Immunological cell: set of structures and biological processes inside an organism that allow it to maintain an internal balance against external aggressions.

→ Summary:

It consists of combining two stimulatory molecules of the immune system and injecting them directly into the tumor, where the immune cells specific for that tumor were already infiltrated. Those specific cells when stimulated by the two drugs, natural immunity destroys the primary tumor and secondary that may be in another organ.

→ Personal opinion:

I think it is a very good scientific advance against cancer and this can save many lives when it is proven and confirmed that it works and eliminates cancer.

China has crossed an ethical barrier by cloning monkeys

China has crossed an ethical barrier by cloning monkeys

→ Glossary:

    -Ovocytes: Immature ovules

→ Summary:

To clone the macaques they need a colony of about 200 females, extracting the oocytes. In China it is easier to have larger colonies than in Europe, but even then there is no clear justification for the cloning of monkeys. There is also talk of the possible cloning of humans in the future. If you practice a lot you could get to do it but it would not make sense to make copies of yourself that you really are not because you would not have the same personality, setting, diet, etc. It would not make logical sense.

→ Personal opinion:

I see well the cloning of animals which their organs can serve us to be transplanted to humans as is the case of pigs in a few years, but the cloning of animals without explanation should not be done and more when large colonies are needed to clone.

TO SLIM, STAND UP

A study published in the European Journal of Preventive Cardiology has

found that standing up replacing the hours we are sitting, we would avoid

weight gain and could even decrease the it.They carried out 46 studies with

1184 participants, with an average of 33 years and being 60% men, 40%

women. The average weight was 65kg. The results showed that if we were

standing for a year we would burn 2.5kg more in a year, and in four 10kg.

Scientific field: Health

Glossary:-cardiovascular diseases: is a class of diseases that

involve the heart or blood vessels.

   -diabetes: Chronic and irreversible metabolic disease in

which there is an excess of glucose or sugar in the blood

and urine; is due to a decrease in the secretion of the hormone

insulin or a deficiency in its action.

  -kcal: kilocalories

Text comment

This could be a good idea, to put some high tables with no chair. This could reduce

a lot the obesity and could also reduce backache.
