A native calcium ion channel has been identified in bacteria for the first time.

In contrast to previous post-mortem or fixed tissue histochemical reports, live calcium and mitochondrial imaging data suggest that the enteric nervous system is not generally affected in Parkinson's disease patients.

Locally recorded calcium events related to slow wave activity show a global cortical fMRI BOLD correlate, establishing a direct relation between a basic neurophysiological signal and the macroscopic perspective of pre-clinical fMRI.

The structure of the calcium channel Orai in an open conformation reveals a dilated pore and gives insight into mechanisms of ion permeation and calcium selectivity.

A new open-source computational toolbox for processing in vivo microendoscopic calcium imaging data performs signal demixing and denoising much more accurately than previously available methods, significantly improving the utility of this imaging modality.

Calcium channel blockers accelerate aortic aneurysm and cause premature aortic rupture in a mouse model of Marfan syndrome through protein kinase C-mediated activation of extracellular signal-regulated kinase.

Genetic analysis of how neuropeptides control C. elegans reproductive behavior shows how T-type calcium channels engage and disengage target neurons from these critical regulators of neural circuits and behavior.

The calcium-dependent signaling pathway during ABA-dependent stomatal closure requires the calcium-independent pathway, and calcium signaling specificity is mediated by PP2C protein phosphatases.

The loss of calcium-dependent D2 autoreceptor desensitization caused by prior in vivo cocaine exposure may be conferred by an unexpected role of the D2L splice variant as an autoreceptor.

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.
