As in humans, the chimpanzees who have the best control over their attitude are also the ones with the best scores on intelligence tests.

In monkeys, intelligence is linked to self-control.

A source of electricity inspired by the electric eel

In addition to this, you will need to know more about it.

By recreating the structure of electric eel cells with hydrogels, researchers have developed a flexible and biocompatible electrical source.

With a voltage of 600 volts and a current of 1 ampere, the electric shocks sent by the eel Eletrophorus Electricus can kill a man or paralyze a horse. Thomas Schroeder, of the University of Michigan, USA and his collaborators succeeded in replicating the mechanism behind these currents by developing an assembly of electricity-generating hydrogels inspired by the cells of the electric organ of the eel.

The mental capacities of animals vary between species and individuals and do not depend on the size of their brains! Several scientific studies affirm it: while hundreds of millions of years of evolution separate us from the octopus, its brain nevertheless allows it to have an excellent memory, a logical reasoning, the capacities of deduction, of innovation, of game, learning, intentions and emotions. Researchers have also shown that animals that have long been judged for no reason possess sophisticated skills. Fish, for example, use tools and cooperate.

The planet captain

Jacques Yves Cousteau was preparing humanity for what the uncontrolled demographic explosion would be for our future ... we were in 1992 on the TV show the hour of truth. Deforestation, soil desertification, extinction of animal species, everything was already contributing to fear of a too uncertain future. Soils strewn with garbage cans in the open air, earth suffocated by toxic products, which tried to spit out the surplus. The Indians, numbering 700 million in 1992, had high hopes of the Ganges. Its more than doubtful waters satiated the inhabitants at first, then praying to purify their sick bodies of ingested bacteria. One and a half billion people did not have access to drinking water. One might have thought that this story had passed, the men become reasonable.

2018: humans always multiply, resources are exhausted. This state of affairs is only more dramatic today, despite the disinformation of certain media which obscure the mortal dangers of humanity which is self-destructing.

The strongest fabric in the world is spider thread

This is an important discovery: researchers have been trying to copy the spider's thread for over a century. It is stronger than steel and as flexible as rubber.

It interests the military or firefighters to make resistant clothing. Doctors, too: miniaturized heart implants have already been produced. This wire could be used to make biodegradable electronic components so replace metal - it would be more environmentally friendly. But here it is, it is a difficult animal to domesticate: spiders do not like promiscuity and devour each other. A German company, AMsilk , has succeeded in having a bacterium produce silk by introducing a spider gene into it; the bacteria manage to secrete the protein that is used to make the thread.

Plants have a sixth sense!

According to the founder of plant neurobiology, author of "The Intelligence of Plants", these are as sensitive as they are essential.

Stefano Mancuso is the founder of plant neurobiology. On his desk in the laboratory at the University of Florence, a zamioculcas and a dracaena are struggling to grow between the piles of books. Beware, however, of denying them the dignity of intelligent organizations. Stefano Mancuso was the first to demonstrate that plants are endowed with the five senses, capable of solving an infinity of problems, of transforming themselves into military strategists or seductresses. Associated with many laboratories around the world, the neurobiologist is considered as a "world changer" by the American press.

Understanding animal intelligence , with the great ethologist and biologist Frans de Waal

In his book: "Are we too stupid to understand the intelligence of animals" (Edition Les Liens qui Libéré), he tells about the ability to design tools of great apes and chimpanzees, the self-awareness of an elephant who is recognized in a mirror, facial recognition in sheep, the cooperation of orcas to hunt seals ... Some features that we find in the human species.


Crows, like jays and crows, are part of the corvidae family, birds known for their exceptional intelligence. For example, the jay can store food in anticipation of future food shortages instead of eating it immediately. Crows have a social behavior similar to that of humans, capable of empathy by, for example, simulating the cries of other animals in specific situations ! A new study published in Science provides a surprising illustration of the intelligence of these animals.

The animals are far from it. The latest advances could end human "supremacy".


By imitating humans, the Japanese macaque shows that it knows how to adapt to its time. If this behavior may be surprising, mimicry is part of the education of this Asian monkey.

The multiple forms of animal intelligence

We could multiply the examples. In recent years, animal science has continued to progress, after - it must be admitted - centuries of human arrogance, when the animal was in our eyes only a brainless beast. Thanks to the contributions of genetics , cognitive sciences and even evolution specialists, we now know that animal intelligence takes many forms, and that it is not the prerogative of so-called superior species ( primates, marine mammals ...).

So, if animals speak, calculate, learn, innovate, what do we have left? Self-awareness ? The altruistic impulse? The feeling of emotions? Again, the latest scientific findings have shown that animals experience sophisticated mental states.

A luminous mushroom!

A fungus with cyanobacteria and graphene printed on it is able to generate a small electric current. This is the discovery of American researchers from the Stevens Technological Institute (New Jersey).

This psychedelic-looking bionic mushroom could belong to the fictional world of Alice in Wonderland or Mario Bros. It is, however, very real. This fungus capable of producing electricity was developed by researchers at the Stevens Institute of Technology (New Jersey). Their project was published in the nanotechnology monthly journal The Nano Letters on November 7.

In addition to this, you will need to know more about it.

To allow the fungus to become a source of energy, scientists create an artificial symbiosis. They print an ink composed of cyanobacteria on the cap of the fungus. The latter provides an ideal habitat for cyanobacteria, and thus allows them to stay alive longer. The bacteria form the green spiral shown in the photo. When the fungus is illuminated, they begin their photosynthesis and produce electrons. These are recovered by the electronic network, formed by graphene nanoribbons also printed on the mushroom.
