Building a morphogen gradient by simple diffusion in a growing plant leaf

The research team has shown that a transcriptional co-activator ANGUSTIFOLIA3 (AN3) forms a signaling gradient along the leaf proximal-to-distal axis to determine cell-proliferation domain. In an ...

Turbulence spreads like wildfire

Every flow is characterized by a dimensionless quantity, known as the Reynolds number, that measures the importance of a fluid's momentum relative to its viscosity. The Reynolds number is low if the ...

Atom-by-atom diffusion offers simple route to longer and thinner nanowires

Researchers in the US and China have shown that diffusion at the atomic scale enables long nanowires of crystalline metals to be fabricated using a single-step moulding technique. The nanomoulding ...
