Researchers identify genes in fruitflies that may shed light on human cancer spread
... are, migrate between other cells and tissues, and travel
to a final destination." Although border cell migration in the fruitfly ovary may seem a far stretch for studying human cancer metastasis, the genes uncovered in this study share more similarities with those that arise from studies of human metastati...
APS lecturer shows rare video of 'teacher-student' immune cell interactions in live animal
...ts with a flea that deposits a few bacteria, which travel
via the lymphatic system to the lymph node and proliferate to huge numbers. One of the puzzles von Andrian has been working on, is how foreign invaders manage to proliferate in the very area, the lymph node, where the immune system is marshaling its ...

Brain communicates in analog and digital modes simultaneously
...tial is a specialized waveform known to be able to travel
down the axon, or output portion of the cell. Due to its length and thinness, the nerve axon has been believed to be impassable to the smaller analog voltage deflections that gave rise to action potential. As this action potential reaches the synapt...
