We are talking about "perfect pitch", that is, the ability to recognize exactly the frequency of a musical note without any kind of reference. For these people, recognizing a note is as natural as the recognizing a color. Absolute pitch is a mysterious gift and causes wonder and questions: what does this feature depend on?? Is it an innate or acquired ability? [...]

In 2014, the term citizen science is included in the new words in the Oxford English dictionary, which defines it as "the collection and analysis of data relating to the natural world by an audience, that adheres to a collaboration project with professional scientists ".
Colors depend on our perception and this can vary from one subject to another. Thus, over time, various methods were born to make the classification objective, to define colors based on coordinates, with standardized light. In the major graphics software there are chromatic coordinates (HEX, RGB, CMYK e HSV) that allow us to better orient ourselves. In the case of red, eg, we can distinguish: magenta, the scarlet, the vermilion, the cinnabar, the red lead, coral, cadmium, the crèmisi, il pompeiano, the purple, the carmine, amaranth, the grenade, it burgundy, the cherry, the terracotta, the Venetian, the Titian, the Valentino, the Ferrari and others.
The story of the Nobel laureate Salvatore Luria, a passionate scientist!
What happens after death, has always been an object of curiosity for man! The different religions, beliefs and traditions, handed down over the millennia, they tried to imagine an unearthly destiny. But on Earth, instead, what remains? Even scientifically speaking, it can be said that there is life after death! The life in question, however, is not ours, but that of a large corpse fauna.

The first tubes of paint appeared around the 18th century. Before then, the artists independently prepared the colors they needed, studying the materials and perfecting the procedures. In ancient Egypt, the pigments were extracted from minerals such as malachite (green), the pyrolusite (nero), la dolomite (White), or from lands such as ocher (yellow and red). The pigments were then amalgamated with a binder, such as egg white or gum arabic.

Someone says that "What does not kill strengthens"! Well, this ancient proverb can be an adequate opening to tell the relatively recent partnership between art and microbiology. Robert Ryman, Twin (1966) https://falzonemarilisa, in fact many bacterial species not only do not kill, but they are even useful for "fortifying" our cultural heritage. falzonemarilisa, of various kinds and invoices, they can be negatively affected by various microbial activities; however it is equally true, than from those same microbial activities, falzonemarilisa [...]
