Biophysicists at Ludwig-Maximilians-Universitaet (LMU) in Munch have developed a new theory, which accounts for the observation that cells can perceive their own shapes, and use this information to ...

Active transport is a process that moves molecules against a concentration gradient. The process requires energy. For plants to take up mineral ions, ions are moved by active transport into root hairs ...

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 ...

·The supply of hydrogen ions will also depend upon their concentration, i.e. the pH of the electrolyte. A concentration gradient in the electrolyte is illustrated. ·If the electrolyte is unstirred, ...

Animals, including humans, need to absorb all glucose molecules from their food. This is taken from the gut wall, inside the small intestine, into the blood. There is more glucose (a higher ...

Composition-dependent stress fields in continuous and mechanically isolated material can, it is shown, initiate and maintain conversion of chemical to kinetic energy. Though the process is analogous ...
