Dictionnaire des Sciences Animales. L'échelle de l'univers, vue interactive. À quoi ressemble l'Univers à petite et à grande échelle ?
L'humanité découvre peu à peu que l'Univers est un endroit très différent selon la proportion sous laquelle on l'envisage. Par exemple, de ce que nous savons, chaque minuscule proton est exactement semblable à un autre, alors que chaque gigantesque galaxie diffère très fortement de ses voisines. À des échelles plus familières, ce qui pour nous est le petit plateau de verre d'une table basse représente pour un acarien un vaste plan étrangement lisse. Toutes ces différentes échelles ne sont pas également explorées. On sait par exemple peu de choses des minuscules gouttelettes que vous produisez à chaque éternuement, et qui pourtant sont essentielles pour comprendre la façon dont les maladies se propagent.

Blue Brain Cell Atlas – Blue Brain Portal. The Blue Brain Cell Atlas provides the densities and positions of all excitatory, inhibitory and neuromodulatory neurons, as well as astrocytes, oligodendrocytes and microglia in each of the brain regions defined in the Allen Mouse Brain Atlas.
Blue Brain’s Cell Atlas was constructed by placing cells computed from whole brain Nissl and gene expression stains from the Allen Institute for Brain Science. Gene expression stains were used to decide the major type of cell. The API provided by the Allen Mouse Brain Atlas was used to access the data. Cell numbers and tissue distributions were validated against values from the literature where available. We found that the literature only contains specific values for 4% of the 737 brain regions. Blue Brain found that experimental data cannot provide ground truth-values and therefore we developed a dynamic cell atlas that can integrate diverse datasets to converge towards ground truth-values, in principle for every cell-type in all brain regions.

You could search all properties or a selected subset only Please provide keywords in the Search Text field and check the properties that you'd like to include in the search. The system will search for the keywords in the properties that you've checked and rank the results similar to a search engine The results will be displayed in the Search Results pane. If the search query hits more than 200 results, then only the top 200 will be displayed.
If you provide more than one keyword, the system will search for items that have all the keywords. Wildcards: You may also use wildcard character * . see examples.
