Let's take stock of what we know about this GREAT ENEMY, what remains to be understood and what is essential to know to better face the period that awaits us.

The eye is a perfect machine, the result of millions of years of evolution. But also a mechanism that can be deceived, as with optical illusions, or defective, as in color blindness. Increasingly refined visual machines are capable not only of seeing, but also of interpreting images and recognizing human faces and gestures.

What are the sleep phases and how do they work? What does it mean to sleepwalk? How does a sleeping pill work? How to improve the quality of our rest? Sleeping is a biological need. Sleep is not just a period of inactivity, it is a time when fundamental things happen in the brain. This is why when we sleep poorly we function less well.

Memory is the basis of learning, but it is also a still mysterious universe. How big is human memory? And what means do we have to increase our ability to remember? The ability that the brain has to simulate the future thanks to memory and how much we can trust what we seem to remember.

How many do we have and why they have different colors. And then, what do we need them for, when did we start dyeing them and how can we make them reborn. In this episode the hair reveals its secrets and also explains what is true in the old and new remedies of popular tradition.

The lifespan of human beings has become much longer. But can we all live to be 120 years old? A short journey to discover the secrets of other species, of what we know about the importance of genetics and lifestyles. Also thinking about the consequences of a world of centenarians.

There is a force that acts everywhere in the universe: the force of gravity. It keeps us grounded, but it has also shaped the universe as we know it. If it wasn't there, everything would be turned upside down. But to find out what it feels like when it seems like gravity isn't there, we asked a famous astronaut.

What triggers that strange spark that makes a certain person strike us and not another? What makes us grow in the desire to know her better and be with her? A question of chemistry, but not only. Here's what studies and research say.

What happens in the brain when you fall in love? Does love at first sight really exist? What is a kiss for? All the answers from science on that "sweet trap of nature" that is falling in love.

It is one of the most important decisions we make in our lives. Genetically we are predisposed to choose the best opportunities to propagate and transmit our genes, but often the decision is the result of a compromise. What do the scientific studies say?

Eating pollutes: however we put it, this is an incontrovertible truth. Already today, food production alone is responsible for 30% of greenhouse gas emissions. But then what should we do? In the meantime, be careful not to waste it, over 17% is thrown away. Then understand that there are foods that have more impact, others less. Eating less meat would be a good place to start. Finally, invest in technology, focus on sustainable agriculture which guarantees the same results but with less water, less fertilizers, fewer pesticides.

If eating pollutes, then let's try to be careful. But how? There are solutions, some have always existed, others looking to the future. If insects, mushrooms and algae have always been present, and with excellent results, in the diets of peoples far from ours, why don't we try to taste them? Or we could eat meat produced in the laboratory, or almond, rice, soy, oat milk, or even 3D printed vegetable steaks: science does not stop and the real challenge to convince us to eat all this will be that... of taste.

What do you eat on a space station when a small crumb of bread could cause irreparable damage? And when we are on top of a mountain? What is the best food for those going to war? And can a castaway survive in the middle of the ocean with makeshift means? Extreme situations that require extreme foods and ingenious solutions.
