Are you ready to solve this week’s science mystery picture and pick up the latest in research along the way? If you know the identity of this object, don’t give it away , but share some interesting (or obscure!) fact about it. Don’t be shy, let your imagination fly.
Hint: This object has the fastest response to light in the biological world.
Why is this cool? A recent study revealed the unexpected finding that the initial response to light was mechanical: light triggered tiny (less than one micrometer) synchronized contractions in this array that then opened mechano-sensitive ion channels to change distribution of electric charge across the surface. This form of signaling is known as mechanotransduction and is faster than more conventional chemical signaling. Do you know of a human sense that uses mechanical signaling?
Image Detail: False colored scanning electron micrograph that is magnified 2,500 times if printed at 10 cm.
Inspiration for Title: THE WHO – See Me, Feel Me – Listening to You (1975)
