WOW!
A commenter at the Uncommon Descent blog has pointed to a very brief but infinitely fascinating discovery.
The original article includes a very short video clip that gets the point across magnificently.
Reminds me of projecting a blueprint onto the ground so you can tell where to build the walls and doors.
The next question must be: What and where is the 'projector'? How are those voltages made to appear in the correct locations?
Sooner or later a tiny handful of scientists may be forced by facts to ask the CORRECT question: Not what is the 'projector' but WHO is the 'projector'?
For the first time, Tufts University biologists have reported that bioelectrical signals are necessary for normal head and facial formation in an organism and have captured that process in a time-lapse video that reveals never-before-seen patterns of visible bioelectrical signals outlining where eyes, nose, mouth, and other features will appear in an embryonic tadpole.
The Tufts biologists found that, before the face of a tadpole develops, bioelectrical signals (ion flux) cause groups of cells to form patterns marked by different membrane voltage and pH levels. When stained with a reporter dye, hyperpolarized (negatively charged) areas shine brightly, while other areas appear darker, creating an "electric face."
"When a frog embryo is just developing, before it gets a face, a pattern for that face lights up on the surface of the embryo," said senior author Dany S. Adams.
