New mechanism uncovered for the reduction of emu wings

.Researchers have uncovered a novel mechanism underlying the skeletal reduction and asymmetry of emu wings. Their research reveals that the absence of distal muscle formation results in a lack of mechanostress during development, ...

An evolutionary battleground: Plants vs. microbes

Gazing out on a freshwater pond, you may see tiny green plants with oval-shaped leaves floating in clusters. In overgrown ponds, these plants coat the water's surface. These plants—called duckweed or water lentils—can ...
