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?


Churchill, retransmitiendo un resumen de su presupuesto en la BBC.

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.

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.

Spanish scientists reverse aging

The team of Juan Carlos Izpisúa successfully used a cellular reprogramming technique to eliminate the damage of time in mice and human cells

A group of researchers, led by the Spanish Juan Carlos Izpisua of the Laboratory of Gene Expression of the Salk Institute of the United States, have taken a step closer to this scientific dream. It would be enough to use a cocktail of four gens to erase the signs of aging. The demostration, with mice and human cells, is presented in the magazine «Cell».
In addition to the US center, the research team has collaborated with the Catholic University of Murcia, the Center Clinic in Madrid, the Hospital Clínic in Barcelona and the University of Michigan School of Medicine.

With the treatment, the cells grown in the laboratory rejuvenated not only in appearance, but in its functioning. The effect was remarkable. The therapy was applied in two types of mice: in a model that reproduces progeria, a rare disease that in humans causes a premature and aggressive aging from birth, and in mice with a natural old age. In the former, treatment prolonged life by 30 percent. "If we transferred this figure to humans, we would be talking about 25 years in a person with a life expectancy of 80 years, although it is still very difficult to extrapolate this figure," Juan Carlos Izpisúa, lead author of the study, told ABC.

In normal mice, the strategy improved the repair capacity of the muscles and pancreas (these two organs were chosen, as others might have been chosen to see their recovery). "We believe that the rejuvenating effects will be observed in all tissues and organs because the molecular basis of aging are common. Mice are not human and we know that it will be much more complex to rejuvenate a person, "he acknowledges.
