Why Do We Forget?

 03/14/2025
Wouldn't it be fantastic if our memory were like a video camera, allowing us to choose what to remember and what to leave behind? And what if we could remember everything? For better or worse, memory doesn't work that way. But forgetting is not a flaw of memory. Thanks to forgetting, we can reason and imagine

Crime Evidence

 09/27/2021
We all know that DNA analysis is useful in identifying criminals who have made a mistake by unwillingly leaving a sample of their body (skin, hair, saliva, etc.) at the scene of a crime.

The Mother Of The Covid-19 Vaccine

 08/06/2021
It is undoubtedly one of the most important scientific discoveries in history. Science, the prestigious scientific journal of the American Association for the Advancement of Science, has considered the development of the first coronavirus vaccines as the main scientific milestone of the year.

El Niño. The dance of the wind and the sea

 06/15/2021
The coast of Peru is inundated with the remains of magnificent pyramids. Archaeologists have discovered that these mysterious monuments that resemble those of Egypt were erected between 6,000 and 3,000 years ago. At the end of this period, however, they were suddenly abandoned. What happened to the civilization that had gone to such great lengths to build them?

Static electricity

 02/25/2021
All the objects we see are made up of tiny particles called atoms. Although the word atom means “indivisible,” atoms are made up of even smaller particles. We did not know this when the atom was named. The particles that make up atoms are called protons, neutrons, and electrons, and they are very different from each other.
Let's make soap!

How to make soap

 01/15/2021
In ancient Babylon, Egypt, Greece, and Rome, soap was being made by boiling animal fats and wood ashes in water. This practice was probably imported to Europe around the 6th century BC by the Phoenicians, merchants who used soap to wash the fabrics they traded for other goods.

Invisible Machines

Wouldn’t it be great if tiny robots could patrol our cells and warn us of potential diseases even before the symptoms appeared? Nanotechnology is already a reality today—and it’s only starting to stretch the bounds of our imagination.

Asteroids: The Threat from Space

 12/12/2016
Every year, tens of thousands of meteorites fall toward Earth. Most of them are very small, about the size of a stone, and end up disintegrating in the atmosphere. But occasionally, these asteroids can have slightly more worrying dimensions, even reaching a few kilometers long. When a this happens, huge blasts leave enormous craters on the Earth’s surface.

Animal Superpowers

 12/02/2016
Many animals stand out for their special abilities: eagle eye vision, dogs refined sense of smell, bats' ultrasonic hearing, salamanders' regenerative powers... Contrary to superheros powers in comics and movies, all these animal powers are real superpowers: they exist in nature and maybe one day we could transfer them to our bodies to become true "superhumans".

Extracting Fall’s Colors

 10/25/2016
Fall shows us 'the other' colors of leaves. Hidden behind chlorophyll, the pervading green pigment of summer leaves, these colors begin to turn as autumn approaches. In this experiment, you will set out to uncover the leaves’ other pigments. To do so, you will apply a technique to separate substances called chromatography.

Birds are living dinosaurs

 03/22/2016
The amazing paleontological discoveries of the last decade have revealed that dinosaurs, rather than having scales all over as we often picture them, were in fact partially or totally covered in feathers. This is particularly the case with velociraptors, the famous dinosaurs from Jurassic Park. These discoveries confirm two hypotheses: originally, feathers were not linked to the ability to fly and instead served a different purpose, and birds are a group of dinosaurs that managed to survive. Birds are living dinosaurs.

Light, colors, and heat
