New research may have solved the mystery of how leaf vein patterns correlate with use of sunlight, carbon and other nutrients. This knowledge could help scientists better understand the complex carbon ...

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 ...

New University of Arizona research indicates that leaf vein patterns correlate with functions such as carbon intake and water use – knowledge that could help scientists better understand the complex ...

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 ...

Elastic stresses may play a crucial role in determining a leaf's venation pattern, according to a new study. Biologists have developed a model that reproduces statistical properties of venation ...

Annals of Botany, Vol. 93, No. 2 (February 2004), pp. 149-156 (8 pages) • Background and Aims In some dicotyledonous leaves and leaflets, the secondary veins run more-or-less straight to the margins ...

Science isn't only about explaining what hasn't yet been explained. Old explanations accumulate their own inertia. It's easy to keep tweaking a familiar and trusted theory, seeking the elusive ...
