But while aminoglycosides are working to kill the bad bacteria, they can also cause some serious toxic effects that can hurt the patient. To learn about side effects and potential toxicity of aminoglycosides, let's visit Jack, a patient in the hospital who is being treated with an aminoglycoside antibiotic.

Somebody say that as the universe is just about 13.7 billion years old from the big bang to now, so if we measure the mass of photon through any quantum effects, we will ultimately arrive at a threshold under which we can not push on. In other words, we have no method to measure the absolute zero mass of photon.
