Corpus: un site pour découvrir le corps humain en 3D
Corpus est un site web qui permet d’explorer le corps dans toutes ses dimensions. De la peau jusqu’au squelette en passant par les muscles ou les artères, plongez au cœur des différents systèmes physiologiques.
Vous aurez également accès à des vidéos permettant de comprendre le fonctionnement des organes, découvrir les dernières avancées de la recherche et réfléchir avec des experts.
Le site junior: la science à portée de clic!
Sur le site ScienceJunior.fr, la science est accessible à tous, jeunes et moins jeunes
Parceque la science n’est pas toujours simple à comprendre, parce que tout le monde n’a pas fait bac +12 en chimie (nous non plus d’ailleurs), ScienceJunior.fr est là.

The abyss: a strange yet poorly known medium.
The abyss (from Greek abyssos meaning bottomless) represent the submarine areas beyond 200 m deep.
These large ocean remain very poorly known as inaccessible (even the Moon's surface is best mapped!).
The Sun's rays are filtered by the water, the darkness is therefore total.
The least almost total. Indeed in this particular environment live funny beings capable of producing light living. This phenomenon is called bioluminescence.
This is also where lives the famous better known under the name of giant squid Architeuthis.
The site of the national Museum of natural history offers you virtually fly a submersible and exploring the abyss and their inhabitants!
The silvery: a terrestrial fish
The silvery is a small fish of ten centimetres, of the family of the gobies, who lives in the mangroves of the tropics.
Its name comes from the fact that it has 2 big eyes above his head that allow an excellent observation of its environment (peri = around; ophtalm = eye).
This fish is also comfortable on land than in water.
Its pectoral fins to move on the ground. It is able to make small bonds and even climb on the low branches of mangroves and attach to it using a suction cup formed by the fusion of its ventral fins.
Like all fish breathe in water through gills.
Out of the water, oxygen enters his body through his skin (cutaneous respiration) either the mucous membranes lining the inside of its mouth (bucco-pharyngeal breathing).
The following documentary presents the biology and behavior of this strange fish:

Giant crystals of the Naica mine
Naica is a Mexican city famous for its mines of which is extracted the sulphur and lead.
It is in these that was discovered accidentally an exceptional cave: the cueva de los cristales (cave with crystals).
Can observe of gigantic crystals of gypsum (the largest measure approximately 11 m long!).
If you want to learn more about this place worthy of the greatest sets of science-fiction movies, watch the video below.
For those who speak Spanish or English, here is the official website of the Naica mine:
Dendrobates or poison frogs
The dendrobates are small frogs colorful living in the equatorial forests (in the hot and humid climate) of Central America and the Brazil.
These frogs have the particularity to produce a very violent poison that coats their skin.
This allows them to protect themselves from potential predators.
Scientists have shown that they were shooting this poison of the toxic insects they fed.
Indeed, it was noted that the dendrobates not living in their natural environment, so not eating these famous insects were very little or even not toxic.
Their bright colour indicating their dangerousness animals wishing to taste.
Some Amazonian tribes use this poison to poison arrows for hunting.

Ecoville: Build your city while respecting the environment
Here is a little game whose goal is to build a city of 15,000 that will grow by managing the consumption of energy as efficiently as possible, by limiting greenhouse gas emissions and waste production.

Cup of raspberry petiole
Is actually petioles of raspberry and petrea volubilis cuts observed under the microscope.
The petiole is the part of the leaf which connects it to the stem.
In this petiole are the vessels leading the SAP.
The eyes and mouth visible in these photos are therefore actually vessels cut.
petrea volubilis petiole cutting
Petrea volubilis is a Liana with blue flowers of the same family as verbenas (the Verbena family)
Nudibranchs are animals sailors belonging to the order of the marine gastropod (such as snails).
The term Nudibranch means that these animals breathe in water through naked gills (= not covered by a shell). On the c-top photography, one can observe the gills that form a feather duster at the rear of the animal.
2 rhinophores, visible tentacles at the front of the animal, are sensory organs that allow the animal to receive the information from his environment.
These animals are in general very strongly coloured and often have original shapes.
For more pictures and information about these pretty original animals, visit the very comprehensive site on the nudibranchs of the South West Indian ocean.
Crim'expo: play the scientific officer
The city of sciences and industry invites you to discover how science puts at the service of the resolution of criminal cases.
Discover the role of the various stakeholders (pathologist, entomologist, legal dentist...) and have fun trying to solve a criminal case you can thus gather clues, analyze them in the laboratory, question witnesses, make portraits robots...
