Scientists directly view immune cells interacting to avert autoimmunity

... cells move very little inside the lymph node. The video microscopy shows that they move about one body length per minute, and that much of the movement is quite directed, for example toward the dendritic cells, rather than random activity. These directed movements are followed by prolonged interaction bet...

Older female fish prefer imperfect male mates, study finds

... and colleagues exposed females of both species to video animations of male fish, one with an equal number of bar markings on each side of the body, and one with an unequal number of bars on each side. The animations simultaneously were projected on opposite sides of a tank, and researchers measured the ti...

High-speed video analyses revealed that flies can flexibly combine, and iteratively improve, these three behavioral adaptations in order to traverse gaps much broader than their own body size. The decisive phase for the climbing success of a fly is the formation of a...
