Structural and functional studies of a potassium ion channel that is opened and closed by different ligands have revealed a novel gating mechanism.

Sugar levels in leaves act as a signal for plants to switch from their juvenile to their adult form by regulating the expression of two genes.

Genetic and electrophysiological experiments reveal that a gene called MCU encodes the ion channel pore that allows calcium ions to cross the inner mitochondrial membrane.

The cisternae of the Golgi contain two functionally distinct domains: the central areas, which remain stationary, and the edges or rims, which are mobile.

The plant hormone ethylene regulates the expression of multiple genes in the model plant Arabidopsis, including those that respond to other hormones.

Efflux of xenobiotic fluoride from microorganisms occurs through a novel family of ion channels with stringent selectivity for fluoride ion and dual-topology molecular architecture.

Optogenetics has revealed that synaptic vesicles can be recycled extremely rapidly in nematodes, indicating that existing models for how synapses 'reload' may need to be revised.

A transport protein enables leaf beetle larvae to take up and store plant toxins and use them as part of their own defense strategy.

The same membrane trafficking cargo can change pathways mediated by different members of ARF-GEF family of vesicle formation regulators.
