Control of a mitochondrial protective mechanism identified

Mitochondria are essential for normal functioning of almost all cells, since they are the main production sites of the energy-carrying molecule adenosine triphosphate (ATP). In addition, mitochondria are the key sites of ...

Chemists synthesize perseanol for the first time

A team of chemists at California Institute of Technology has totally synthesized perseanol using a 16-step process for the first time. In their paper published in the journal Nature, the group describes their process and ...

The pH of calcium ions controls ion channel opening

Ion channels are pores in the membrane of cells or cell organelles. They allow positively or negatively charged particles, so-called ions, to be transported across the membrane. Biochemists at Johannes Gutenberg University ...

Single molecule puts sperm on track

Sperm start their sprint to the ovum when they detect changes in the environment through a series of calcium channels arranged like racing stripes on their tails. A team of Yale researchers has identified a key molecule that ...

New study uncovers the interaction of calcium channels

Korean researchers have identified the interactions of the combinants among calcium channel proteins that exist in nerve and heart cells. The result opened a new path of developing treatments for high blood pressure and brain ...

Communication via calcium wave

Based on what we know today, the plant hormone auxin influences all aspects of plant growth and development. It makes corn thrive from germination to harvest, causes trees to grow skyward and date palms to produce sweet fruits. ...
