Rolling dice for cell size specification in plant leaf epidermis

One of the central questions in biology is how a cell specifies its size. Because size distribution often shows a characteristically skewed pattern in a tissue, there may be some stochastic option for determining cell size. ...

Random process may determine specialized cells in organs

What is the process that allows plant and animal organs to produce different specialized cells from an original set of identical cells? In the case of small and giant cells found in the sepals – the leaf-like covering of ...

See flower cells in 3-D—no electron microscopy required

Scientists require high-resolution imaging of plant cells to study everything from fungal infections to reproduction in maize. These images are captured with scanning electron microscopy (SEM), where an electron microscope ...

Fertilisers play key role in reducing crop pests

While "preventative medicine" is well-known in human health, it's becoming a buzz word in crop production as researchers discover how the risks of damage by pests and diseases may increase if crops don't get enough nutrients ...

Nanoparticles may enhance cancer therapy

A mixture of current drugs and carbon nanoparticles shows potential to enhance treatment for head-and-neck cancers, especially when combined with radiation therapy, according to new research by Rice University and the University ...
