How mantle movements shape Earth's surface

The movement of tectonic plates shapes the rocky features of Earth's surface. Plates' convergence can form mountain ranges or ocean trenches, and their divergence can form oceanic ridges. But it's not just the plates themselves ...

Flowers may be more ancient than dinosaurs, but scientists can't agree on when they evolved

Flowers may look delicate—but flowering plants, what scientists call angiosperms, are one of the most successful evolutionary organisms on the planet. Including more than 350,000 known species, they dominate the ecological ...

A nanoscale look at how shells and coral form reveals that biomineralization is more complex than imagined

Exactly how does coral make its skeleton, a sea urchin grow a spine, or an abalone form the mother-of-pearl in its shell? A new study at the Advanced Light Source at the Department of Energy's Lawrence Berkeley National Laboratory ...
