Biophysicists from the University at Buffalo are using a protein from the venom of the Chilean Rose tarantula to combat death from heart attacks.

The walls of your cells have tiny channels that open when the cell stretches. Among other body functions, these channels are responsible for the contraction of heart muscles.

When these channels open too wide which can happen from stretching the heart muscles over time, they allow a flood of positive ions into the cell. These extra ions disrupt the electrical signals in the heart, causing the organ to fibrillate ,beat wildly and irregularly.

The protein from the Chilean tarantula venom binds to these channels, which can block the positive ions from passing through. This could ostensibly prevent fibrillation and hopefully death if delivered during a heart attack.
