Scientists thought for a long time that plant roots followed a simple rule: the deeper you go, the fewer roots there are. But a new study published in Nature Communications has turned this long-held belief on its head. It shows that 20% of plants around the world grow a second set of roots more than ...
The highest mountain in Africa, Mount Kilimanjaro, is a land of extremes where equatorial heat gives way to Arctic ice in barely a few thousand meters. But tucked among its dramatic slopes is one of the most unusual botanical beauties in nature: the giant groundsel (Dendrosenecio kilimanjari). Rising nowhere else on Earth, these towering plants ...
Physicists have uncovered the mechanical forces that shape the iconic structure of rose petals, revealing how geometric frustration influences their curling patterns. This discovery provides insights into the physics of natural growth and could inspire new developments in shape-morphing materials. Understanding Geometric Frustration Unlike most flowers, which exhibit wavy or smooth petal edges, roses develop ...
When birds feed on nectar from flowers, they do more than just get a meal—they play a crucial role in pollination, transferring pollen from one flower to another. But how well do the shapes of their beaks match the flowers they visit? A new study on Australian honeyeaters feeding on spotted emu bush (Eremophila maculata) ...
