Is it true that there is a "fifth taste"?

At school we have been taught that there are four basic flavors: sweet, salty, bitter and acid , but in recent years there has been a need to take into account a fifth flavor, which until the moment had been overlooked.They call it " Umami ", which in Japanese means something like "pleasant or tasty flavor". Although we have to make a nuance.There are many those who refuse to accept the existence of this fifth flavor.The reason? Because more than a flavor that we can all identify, the umami would be rather a perception, an indefinable sensation that does not abound too much in our food and that only chefs strive to seek to give their dishes an almost addictive flavor.Have you ever asked why Japanese food is so tasty ? Or why do we like french fries or snaks so much? Why most contain umami, or what is the same "monosodium glutamate". But what does the "Umami" taste like? Here comes the key question: what does the Umami taste like? Scie...

Manage your fears | The RIA method

In the following article we want to talk to you about controlling your fears.Fear is something destructive that, although it exists to keep us alert to possible dangers, usually has not so beneficial consequences.Fear of speaking in public, on a first date to a job interview, and many other situations in which fear is our worst enemy because it usually blocks us. So the next time you have to control your fears, you should follow the researcher's advice of fear Mary Poffenroth and her RIA method that we will explain below.

And you, also "procrastins"?

And you? Procrastines too? If you don't, we are sure that you know someone who does it continuously and that, surely, makes you despair.But what does this disturbing word really mean? Let's give an example: you have been dating a person for a long time, you make plans for the future, you have many illusions and projects, however, your partner never seems to decide.He is unable to formalize your relationship because something like that, not only overwhelms him, but even He is lazy. "Are we not well like that?" I often reproach you. Let's give another example: you may have the classic friend who never seems to finish his studies.It is easy to be an "eternal" university student who faces the responsibilities and anxieties of the working world. And what about people who spend all their time in front of a computer screen letting out "real life" ? Sometimes, it is much easier to let ourselves go, evading responsibilities, than to put means t...

Here we go! 6 facts about Einstein that you surely do not know 1.Its authorship on the theory of relativity was debated The theory of relativity was full of accusations of plagiarism by German scientist David Hilbert and his supporters, because Hilbert claimed that it was he who had first discovered the theory and that Einstein had taken all the credit .In his defense, Einstein I affirm that it was Hilbert who had copied some of his documents. At the beginning it was thought that every scientist had discovered the theory by his side, but that was until it was discovered that, in fact, Hilbert had stolen some documents of Einstein without giving him any credit.

Will there be a Mega Tsunami in Hawaii? If you are a reader from Science Daily Online and you live in Hawaii do not panic, apparently the possibility that a mega tsunami hits the Hawaiian archipelago in the next 50 years is only 3%, and this information is derived from a study of 5 years by researchers at the University of Hawaii at Manoa (UHM), which began just shortly after the 9.0 earthquake that shook Japan in 2011, and was followed by an even more devastating tsunami. The Investi gators evaluated the behavior of the different plates and tectonic faults that cause earthquakes and tsunamis in the Pacific, as well as the behavior of some large tsunami...

What will humanity be like in 1000 years?

We are taller, we live longer and we are healthier than ever.Besides, thanks to advances in technology, we can search almost any imaginable piece of information on Google (along with kitty videos). What will humanity be like in 1000 years? That is what has happened to the human species in the last 1000 years or so, but what will happen to us in the next millennium? Some scientists offer fascinating and provocative answers , about the color of our skin and the shape of our body, even how long we can live. As we go further in the future , the increase in temperature, accompanied by the deterioration in the protective ozone layer, will make the skin darken as part of an evolutionary improvement, since it will protect us against UV rays.temperatures can also affect our size. We will have longer and thinner bodies to better dissipate excess body heat. These remarkable changes would take more than 1000 years to appear, But the idea that the human being of the future will chan...
