We know that cells maintain their water content through osmosis. Now we can see what happens when someone deliberately screws around with osmosis. Some cells explode. Others turn into “ghosts.”
For the first time ever, molecular biologists have filmed the death of a human white blood cell. But the video shows something else, too. These integral components of our immune system do not go quietly into that good night. Rather, they go down alerting their neighbors to the presence of potential pathogens.
The human body is such a magnificent thing. Just check out this video that shows how our immune system works. When a parasite finds its way inside a place where it clearly shouldn't be, white blood cells immediately start rushing to the rescue. It only takes a few seconds for the parasite to get swallowed.
From a nail-bitingly tense chase sequence all the way to a seemingly impossible run down an all too narrow alleyway, this video of a ridiculously-dogged white blood cell in hot pursuit of some fleeing bacteria is a master class in suspense done right.
To give you an idea of how micro this video is, those dots you see moving diagonally toward the top of the screen are individual white blood cells. What you're looking at is a microchip that sorts out white blood cells from a blood sample. It makes a great visual, but more importantly, it could seriously improve the…
