Washing your hands with plenty of water and soap eliminates most of the bacteria and microorganisms that can harm us, but this disinfection work almost never achieves its purpose under your nails.

In the anus s 80 the Department of Dermatology of the University of Pennsylvania conducted a test thoroughly cleaning the hands of about twenty volunteers, and then subjected them to an examination in which they were able to detect thousands of bacteria in the subungual zone , as the area of the skin under your nails is called.

The researchers concluded that the space between the skin and the nails provides a perfect refuge to bacteria and microbes, thanks to the protection given by the one and the humidity present in this space.They also showed that the artificial ones extend the protection to the bacteria and that the nurses who used these accessories had more contaminated hands than those who preferred their natural ones.

Frequent bacteria in the subungual area are the pseudomonas , which in normal situations give a gray tone under your nails , eg ro that in some serious cases can give the ones a green color .

Later studies in 2000 and 2002 confirmed these conclusions, and others in the 90s indicated that the use of Enamels and some paints did not help to improve hand hygiene.

A black hole will be photographed in 2017

2017 will be a year of challenges for astronomy, and in particular for the study of our solar system and the galaxy it is in.With some luck it could be the year that we managed to have the first photograph of a black hole Thanks to an international project, the Event Horizon Telescope . A black hole will be photographed in 2017 We will tell you a story that could reach a climax in 2017, but which began in 1971, when Martin Rees and Donald Lynden-Bell proposed the hypothesis that in the center of the Milky Way , our galaxy, there should be a supermassive black hole, which they named as Sagittarius A * , to differentiate it from the rest of the central sector, known as Sagittarius A, and to indicate that something very special was happening there. Supermassive black holes are usually found in the center of galaxies and there is still no cons among astrophysicists about how they originate, but they could play a fundamental role in the stability of elliptical and spiral galax...

How do we notice the flavors in the tongue? A myth to overcome

At school we learned that we have taste receptors that help us identify the different flavors in the language; made us draw a diagram with regions marked according to the taste to which it corresponded; bitter on the back, sweet on the front, salty on the sides and in the front and sour on the sides on the back, however, as when we were told that Pluto was the ninth planet in the Solar System and this idea changed with Over the years and new discoveries, it turns out that the way we notice the flavors in the language is not as simple as they told us. How do we notice the flavors in the language? A myth to overcome Where does the taste sensation come from? This is given by a chemical stimulation that occurs in the taste receptor cells that, when grouped in a bouquet, become taste buds.There are three types of papillae that help us identify the flavors in the tongue and acquire their name depending on the way in which their cells are grouped: goblet, foliate and fungiform. S...

Why don't we die crushed by the weight of the atmosphere?

The air around us seems ungrateful, but it really isn't like that.The air is made up of an incredible number of molecules and these, however small, have a weight.Scientists say the weight of the atmosphere it supports our head is the equivalent of that of a small car.Then, why don't we die crushed by the weight of the atmosphere? Join us to discover it! We don't die crushed by the weight of the atmosphere As we have said, the air molecules that make up the atmosphere, although they are too small for us to see, have a certain weight .One by one they have a weight practically non-existent, but together, at sea level, they cause a pressure on our body equivalent to 10,000 kg.per square meter.About 10 cm.squared the pressure is 1,000 kg., that is a ton.our head we have an atmospheric pressure equivalent to the weight of a car small...and yet we don't die crushed by the weight of the atmosphere . The answer to this phenomenon is in balance .The pressure in the...

Is it a zebra or is it a donkey? No, it's a "ceburro"

No, it is not a pun.The birth of this beautiful zeburro is the result of a hybrid cross between a zebra and a donkey. As often happens with zebras and donkeys , creating unique and sympathetic zebrasans that raise so much expectation among animal lovers. This curious phenomenon has recently originated in a small Crimean zoo, where apparently some species coexist quietly with the others, until in the end nature has played with chance to create a new tenant whom they have called «Telegraph» .If the purpose of zoos is precisely to conserve all species at risk of extinction, it seems that biology has taken a step further to offer us this little gift: the ceburro. Ceburro.The sympathetic hybrid of the zoo The ceburro born in Crimea has received the original name of «Telegraph» in honor of a newspaper of l country .As you can see in the picture his whole body is reminiscent of that of a donkey, but its legs are painted with the typical strokes of a zebra.A precious nature that, unfo...

The saddest whale in the world

As they say it is the loneliest whale on the planet .As we know this species of marine animals usually live in groups, in large family groups where they establish strong bonds through which they face adversities. They only separate from their units once in a while, when a whale is about to give birth, for example.It temporarily moves away, for days after returning with its own.Nothing more.They are therefore wonderful creatures who enjoy living, growing and traveling with their own.But biologists discovered a rare exception in 1992.A whale that, for some reason, has been living alone for more than 22 years . The curious case of the lone whale Already in 1992 a group of biologists discovered in the fjords of the North Sea, something really peculiar.How could it be that a whale advanced in solitude for so many days in that area? During the time they were watching her, they never saw any other specimen approaching her.She simply limited herself to swimming in the most complet...
