A tiny sensor that can hear the subtle electrical signals naturally emitted from cells could be used one day to listen for cancer.

The “microelectrode cell array” has the potential to detect tumors much earlier than current methods and help develop drugs that effectively kill cancerous cells.

The sensor is a specially designed semiconductor chip that contains an array of electrodes, each no wider than a human hair,… read more

A tenuous connection has emerged between stress, the immune system, and cancer, with a surprising new insight that is changing the direction of research: it now appears that cancer cells make proteins that actually tell the immune system to let them alone and even to help them grow.

One immediate consequence of this line of thinking is a new idea for treatment: scientists could seal off the cancer cells’… read more
