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).

Ticks (and what suits us)

2023-05-31T15:56:17+02:0031 May 2023|Categories: Environment, Nature|Tags: , , |

Certain areas of our country, and of the world at large, every summer they deal with the tick alarm! For a few years though, the spread of these dangerous arthropods is also affecting environments other than those known, the Alpine regions are a sad example of this. Once again, therefore, we find ourselves having to deal with the negative consequences of climate change and the increase in global temperature. But what about climate change with ticks?? And why they are so feared?

The world in recent days has bid farewell to a queen that undoubtedly represented, for better or for worse, an iconic character of the last 70 years. During her reign, Elizabeth II was a witness and protagonist of striking intertwining between economics, science, tradition and politics. Here we want to recall a catastrophe that was an irrefutable demonstration of the correlation between environmental causes and health outcomes, and had consequences in the years to come. It was the year 1952 and in the first days of December, due to thermal inversion, a black blanket enveloped London. Initially, no one seemed to care, il cielo della città era [...]

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? [...]

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": [...]
