Cancer cells have a terrifying-yet-ingenious way of passing through even the smallest blood vessels to spread throughout the human body, according to a new study by researchers at Massachusetts General Hospital. Figuring out how to prevent them from doing so may help slow down the spread of this killer disease.
We've heard a lot about self-assembling structures, but we rarely get to see a cool visual demonstration. This video shows several shapes and even complex, interlocking structures being assembled through "microfluidic channels."
J Tanner Nevil is a microfluidics expert who occasionally likes to turn his laboratory into an art studio. Here, you can see that he's turned his microfluidic chip — often called a "lab on a chip" — into a painting made entirely by piping tiny amounts of colored fluid into canals that are about 20 microns in width.…
