Vídeos científicos: Muito bons!

Carlos Henrique Costa fez uma indicação muito boa: The Inner Life of a Cell

"Caros amigos,
Divulguem esta obra-prima de conhecimento e arte!"

Aproveito para indicar o também muito bom Antibody Immune Response

"This 3D medical animation shows how antibodies stop harmful pathogens from attaching themselves to healthy cells in the blood stream. The animation begins by showing normal red and white blood cells flowing through the blood stream. Next, a single pathogen appears onscreen slowly moving toward its destination on the surface of a cell. The tubular extensions on the pathogen are surface proteins which attach to
corresponding surface proteins on a white blood cell, or leukocyte. As the animation continues, more pathogens continue to attach to the white blood cell, rendering it ineffective.

During the immune system response, Y-shaped antibodies begin attacking the pathogen, binding to its surface proteins as the pathogen attempts to anchor to the blood cell. The antibodies completely block the pathogen from attaching to the blood cell, "tagging" the pathogen so
that one of the immune system's leaner cells, a macrophage, appears onscreen to engulf and digest the pathogen.
