Scott Kelly, the astronaut rejuvenated in the space

This is the experiment carried out in NASA that is to distinguish between two twins, Mark and Scott Kelly, two astronauts determined to use this mission.This mission has been carried out to find differences between these two twins, one of them that are on earth and at the same time as another in the space. The difference that has attracted the attention of researchers is a study on the telomeres. Are the ends of chromosomes.It has been observed that their telomeres were lengthened space during the stay. Now researchers are trying to find out the cause because, warn, could simply be due to physical exercise and diet that Scott followed during the 340 days on which it was orbiting the Earth.

NEWS 6: Appears a lost essay by Churchill about science and space exploration

He wrote it in 1939, but the 11-page document hasn't appeared until 2016 in a United States museum.


Churchill hoped to publish it in the News of the World Sunday, but the war interrupted this plan.
The first sketch of the article is dated around 1939, but according to the astrophysicist, "reviewed it slightly in the late 50's while staying in a villa in the south of France, with its publisher, Emery Reves. Finally, Churchill changed the title of

Are We Alone In Space? Are We Alone In The Universe?

SOME EXTRACTS OF CHURCHILL

"One day, possibly not in the not-too-distant future, it might be possible to travel to the moon, or to Venus or Mars," Churchill wrote in this 1939 essay.

However, he distrusts travel or even interstellar communication, pointing out very accurately that it would take five light years to go and return to the nearest star.

"I am not so impressed by the successes we are achieving in our civilization as to think that we are the only point in this immense universe that contains creatures that live and think or that we are the highest type of mental and physical development that has appeared Once in the enormous compass of time and space. "

Despite its moral conservatism, the discovery of this piece of history reaffirms the condition of Sir Winston Churchill as a man of progress and enthusiast of science,

Eat less and well

The researchs confirms that a caloric restriction extends primates life and, above all, improves their quality in old age


Eatting less does not mean to follow the traditional diet to maintain the weight, of the style 2,500 or 3,000 kilocalories daily, that usually advise the nutritionists. It means eating less than that, maybe 30% less. That is, it means going hungry, and also keeping an exquisite care so that there is no lack of essential nutrients in the diet. The second is that the confirmation we are talking about is for the moment in non-human primates, so that we still do not have the bomb-proof confirmation for human primates.

Extending life has undoubted power, but scientists and doctors are much more interested in the other side of the issue: that calorie restriction improves life even if it does not lengthen it. It warns against the four horsemen of the apocalypse in developed countries: heart attack, cancer, diabetes and neurodegeneration.
The reason is that it slows down the aging, and with it the appearance of all those diseases that are the easements of the age. This is precisely the kind of preventive medicine we need, because continuing to base the increase in average life expectancy on increasingly expensive heart attack treatments is unsustainable even in the medium term. And the export of our Western fat festivals to developing countries threatens to generate a planetary pandemic of obesity, disease and premature death.

Commentary

In my opinion this text speaks of a complicated subject that is the food and generalizes enough, since we can not base this thesis of eating less in our day to day without consultation to a qualified professional

So will be the explosion that could change the sky in 2022 - (Noticia4)

So will be the explosion that could change the sky in 2022

Although we understand the sky, as something quiet and still, there are many things unexplained and ''Invisible'' for us.Out there the galaxies "collide", the stars are born and die, and there are bursts of energy capable of traveling thousands of millions of light years away.Although the sky is eternal as the distances are enormous.Larry Molnar, an astrophysicist at Calvin College announced that in 2022, we will see a significant change in heaven with our own eyes  as two stars merged into one and created a powerful explosion, known as nova, which will become a new point of light in the sky.And it also says that for the first time we can observe a two-star system before and after the merger.
The history of this prediction began in 2008. By then the astronomer Romuald Tylenda watched the stars, V1309 Scorpii. The object behaved strangely and suddenly broke out, in the form of red nova, a type of explosion that had been introduced only shortly before. The Tylenda data showed that, prior to the outbreak, the orbit of the star was closing faster than ever.According to the astrophysicist Larry, if his prediction fails, it will not be bad at all. The reason for this is that then they would have to prove that they should seek the reasons for the behavior of KIC 9832227 in another part. "Discover why undergoes certain changes in its brightness, it would also be an important discovery, though not as nice as a new point in the sky", has joked Molnar.

I believe that there is no conclusion in this news, because it is a hopeful and that it is not known if you will. In my defense I can say that I love the world of astronomy and astrophysics and I find it very interesting because we can evolve thanks to this nova explosion of two stars) no matter what happens, we will evolve in one way or another.

NOTICIA DE LA SETMANA 4: "Malaria case tests two thousand years ago".

-Summary

An analysis of 2,000-year-old human remains from various regions of the Italian peninsula has confirmed the presence of malaria in the Roman Empire. The finding could provide definitive arguments for the long debate about the existence of the disease in this ancient civilization. 

The key is in samples of the mitochondrial genome of malaria, extracted from the teeth of skulls buried in three Italian cemeteries, dating back to the Imperial period from the first to third centuries of our era.

   

-Glossary

Mitochondrial genome--> genoma mitocondrial--> The mitochondrial genome is the genetic material of the mitochondria, the organelles that generate energy for the cell.

-Commentary

I think is surprising that a disease stay active since third century.

NOTICIA DE LA SETMANA 1: "Subtle helium emanations as predictive signal of imminent earthquake".

-Summary

Japanese researchers have found that, as some have suspected, there is a relationship between helium levels in groundwater and the amount of stress exerted on Earth's inner rock layers. This has been seen in localities near the epicenter of the Kumamoto earthquake of 2016. Scientists hope the finding will lead to the development of a surveillance system capable of detecting changes in tension that could portend a major earthquake.

Several studies, including some on the great Kobe earthquake in Japan in 1995, have indicated that changes in the chemical composition of groundwater may occur before seismic movements. However, researchers still needed to accumulate evidence to link with sufficient certainty the occurrence of earthquakes with such chemical changes.

A team of researchers from the University of Tokyo in Japan and their collaborators found that when the stress exerted on the earth's crust was high, so were the levels of an isotope of helium, helium-4, released into groundwater Near the epicenter of the 7.3-magnitude Kumamoto earthquake in southwestern Japan, which caused 50 deaths and serious material damage.

I think that this will be very usefull to detect the possible earthquakes in the future.
