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 ...
A leaf may appear to be one of the simplest structures in nature, thin, delicate and easily overlooked. At first glance, it ...
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 ...
Overexpression of SHR enhance mesophyll cell division, resulting in a substantial reduction in leaf vein density. However, exogenous auxin treatments led to an increase in leaf vein density. Notably, ...
Nature is a great architect, and the vascular network – or veins – of a leaf are key to its structure. Mathematical physicists at Rockefeller University use fluorescent dye and time lapse photography ...

The Mathematical Treatment of Leaf Venation: the Variation in Secondary Vein Length along the Midrib
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 ...
Researchers in Iraq have developed biomimetic leaf vein–inspired fins for photovoltaic panels, with reticulate (RET) venation reducing panel temperature by 33.6 C and boosting efficiency by 18% using ...
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 ...
