X-ray images give unprecedented view of extremely rare type of supernova. New information suggests that these supernovae start as compact stars that lose mass at the end of life. Calcium-rich ...

Takashi Hishikawa, Joseph Y. Cheung, Rao V. Yelamarty and David W. Knutson The Journal of Cell Biology (JCB) is a not-for-profit publication, edited by scientists, and a leading life sciences journal.

The mechanism of skeletal muscle contraction is a process that relies on calcium signaling. However, the physiological role of calcium-induced calcium release (CICR) through the ryanodine receptor ...

Left: A blue light pulse of 0.1 seconds triggers a calcium signal (red) in guard cells, which is followed by an anion current (black). Right: The influx of calcium into the cell promotes the release ...

A supernova first detected in 2005 changed humanity’s perception of the Universe, and one of the minerals needed to support life — calcium. Researchers eventually determined that the explosion, and ...

Researchers have developed a novel method for simultaneously recording action potentials (APs)—temporary changes in electrical potential when cells become excited—and calcium transients—calcium ...

Mitochondria are crucial for maintaining calcium balance in cells, but their calcium dynamics are challenging to study due to pH changes in the mitochondrial matrix, and the lack of cyan-colored GECIs ...
