The physics of pollinator attraction SUMMARY: This article focuses on the physical properties of plants that have evolved to help them select the appropriate pollinators and discourage non-pollinators (nectar stealers). The first feature the article addresses is the shape of the cells. Flower petals often have cone-shaped cells to help scatter more light. This gives… Continue reading The physics of pollinator attraction

Mechanics dictate where and how freshwater planarians fission SUMMARY: Planarians are tiny squishy worms that go through binary fission by ripping themselves in two parts: the head part and the tail part. This article looks at the mechanism of the ripping. First, there is the formation of the waist, then pulsation of the head, then… Continue reading Planarian Fission
