Some plants, such as succulents, have managed to grow very plump leaves. For that to happen, according to a new study, plants had to evolve three-dimensional arrangements of their leaf veins. That's ...

You might assume that a leaf's vein patterns fork, like tree branches splitting into twigs as they get further from the trunk. But peer carefully and you'll see that the veins make innumerable closed ...

UCLA life scientists have discovered new laws that determine the construction of leaf vein systems as leaves grow and evolve. These easy-to-apply mathematical rules can now be used to better predict ...
