A potassium blood test is used to measure the amount of potassium in your blood. It is part of a panel of blood tests called ...

Ion selectivity is an important property of cell membrane ion channels. For example, potassium ion channels are more permeable to potassium ions than to sodium ions. The mechanism underlying the ready ...

Despite being only a few nanometers in size, they are of fundamental importance for biological processes: Ion channels allow essential ions such as potassium and sodium to enter and leave our cells.

Do only potassium ions pass through the selectivity filter of a potassium channel, or are there water molecules between the ions? This question has been a source of controversy for years. Researchers ...

Scientists have developed a nonflammable electrolyte for potassium and potassium-ion batteries, for applications in next-generation energy-storage systems beyond lithium technology. Scientists explain ...

Two studies by scientists at the University of Chicago have demonstrated a new way to look into the inner workings of cells—in particular, to track the flow of ions inside the many tiny organelles ...

Potassium channel blockers are a type of medication used to treat conditions like cardiac arrhythmias. They block the movement of potassium channels in the body, disrupting the body’s electrical ...

Potassium is a nutrient in food that helps your body run smoothly. Too much potassium in your body can cause health problems, but a simple blood test can measure your levels. Potassium plays a role in ...

Potassium-ion batteries could have a higher energy density than sodium-ion batteries. This is important for large-scale energy storage such as for renewable energy. Image Credit: Science and ...
