Keep this in mind: Scientists say they've learned how your brain plucks information out of working memory when you decide to act.
BK channels (large-conductance, Ca2+-dependent K+ channels) are essential for the regulation of important biological processes such as smooth muscle tone and neuronal excitability.
TEL AVIV, Israel, August 9, 2010 /PRNewswire/ -- A new study conducted in the department of Biochemistry and Molecular Biology at Tel Aviv University (TAU) elucidates the way in which toxic, yet essential, copper ions enter human cells.
Conventional die castings can be made stronger using new, more environmentally friendly technologies developed by CSIRO.

Before one of your muscles can twitch, before the thought telling it to flex can race down your nerve, a tiny floodgate of sortsâ€”called an ion channelâ€”must open in the surface of each cell in these organs to let in the chemical signals that spur the cell to action.
Hemichannels are connexin channels that can dock with each other to create a gap junction across two plasma membranes.
One of the biggest mysteries in molecular biology is exactly how ion channels â€“ tiny protein pores through which molecules such as calcium and potassium flow in and out of cells â€“ operate. Such channels can be extremely important; members of the voltage-gated ion channel family are crucial to generating electrical pulses in the brain and heart, carrying signals in nerves and muscles. When channel function goes awry, the resulting diseases â€“ known as channelopathies,...
