Large crystals growing in water often form from tiny nanocrystals continually attaching together. During attachment, these tiny particles snap to the surface, like LEGO bricks. A bit of torque is needed to rotate the particles ...

Slowly flapping its orange and black wings, a monarch butterfly sips liquid from a patch of mud. Its proboscis – the mouthpart that sucks up liquids – grazes the damp soil. For years, biologists knew that butterflies ...
