A finely tuned system evolved early on to help cells survive in a world where good times come as fast as they go. Now investigators have shown that the system is switched on by way of the mTOR protein.

Just as cell phones and computers transmit data through electronic networks, the cells of your body send and receive chemical messages through molecular pathways. The term "cell signaling" was coined more than 30 years ago to describe this process. For the first time, scientists have quantified the data capacity of a biochemical signaling pathway and found a surprise -- it's lower than a dial-up modem. Science is publishing the discovery made at Emory and Johns Hopkins.
