A woman is dispensing reagents using a motorized pipettor. She is in a stylish kimono (hogusome) with a pattern like letters written with a brush. The text on her kimono is not only for fashion but also actually the recipe for the reagents (NaCl, glucose, amino acids, acetic acid, etc.); that is exactly to kill two birds with one stone. It will help her do experiments precisely at the busy end of the year.
It is known that an increase of cytosolic concentration of calcium ion (Ca2+) like a wave is initiated from the point of sperm entry and propagates throughout the egg after fertilization in many animal species. This calcium wave is caused by a kind of chain reaction; activated phospholipase C (PLC) produces inositol 1,4,5-triphosphate (IP3) that induces release of Ca2+ from the endoplasmic reticulum (ER) near the egg surface, and released Ca2+ induces further release of Ca2+ from nearby ER. The leaves on the round-shape mountain are turning red like a wave coming down from the top of the mountain as if mimicking the calcium wave.
