About Marilisa Falzone

Master's degree in biology, specialization in biomedical and molecular sciences. Born in Sicily, she lived in different places along the Italian boot, first for study and then for work. Teaching is in her past and perhaps her future. She is currently working as a fellow for the Environment and Health project. She likes to write about all the nuances of biology, of other scientific curiosities and nonsense (but the latter keeps them for herself).

The secret of absolute pitch

What Ludwig van Beethoven has in common, Barbara Streisand, Jimi Hendrix e Pippo Baudo? You could add to this list several other more or less known names, who have discovered to possess this feature more or less by chance. 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 humans, otherwise you are authorized to release a regenerating yawn. Given the universality of this daily reflex, we may be led to think that the mechanisms and purposes that underlie it no longer have secrets.. The truth is that we have always been familiar with it but we have known it recently and not entirely. Let's start with a trivial question: otherwise you are authorized to release a regenerating yawn?

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.

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. Fear, eh? After death, the decomposition process begins immediately, as the cells no longer receive oxygen and other nutrients that allow them to survive. It follows a process called "autolysis": [...]

The Egyptian blue, between art and science

2021-07-16T21:37:24+02:005 April 2020|Categories: Curiosity|Tags: , , |

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. The Egyptians didn't just extract what they found in nature, but they came to produce, more than 5000 Years ago, the first known artificial color: the Egyptian blue! [...]

Traveler's diarrhea

It is a gastrointestinal disorder due to food poisoning. It manifests itself with an increased frequency of bowel movements that lead to three or more evacuations of poorly formed stools per day, generally during a trip abroad, often in a developing country. What are the etiological agents? In more than half of the cases the cause is not investigated because the symptoms disappear before returning home. When, on the other hand, the causative agent is sought, these bacteria are almost always found: Enterotoxic Escherichia coli is the most common bacterium responsible for traveler's diarrhea whose infection occurs [...]

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 [...]
