Biochemists found that as active transporters in cell membranes undergo conformational changes to allow their main substrates to pass through through, small molecules like water slip through as well.

Inspired by micro-scale motions of nature, a group of researchers has developed a new design for transporting colloidal particles, tiny cargo suspended in substances such as fluids or gels, more ...

The cytosolic free calcium concentration of higher plant cells is maintained at about 0.1 μM by the action of membrane calcium transporters. These act to remove calcium from the cytosol and expel it ...

Measurements have been made of the electrical potential difference between the exuding sap of detopped castor-oil plants and a nutrient solution bathing the roots. The initial concentrations of the ...

Boron, though required only in minimal amounts, is vital for plant development. It strengthens cell walls and supports the growth of roots and shoots. Normally, boron, in the form of boric acid, is ...

The link between nucleocytoplasmic transport and apoptosis remains controversial. On the one hand, nucleocytoplasmic exchange of molecules (reviewed in Ferrando-May et al. 1) seems essential for the ...

Seeking students to contribute to research exploring motor-disease protein complexes and their role in intracellular transport, as they relate to disease initiation and the aging process, and the ...
