It's not the whole ear they are trying to grow but rather the pinna. The ear is the entire organ which includes all the structures of the inner ear, middle ear and outer ear. The pinna is the visible part of the ear.
All I know is ball... and good... and RAPE.
I think the point is that alcohol based sanitizers won't create antibiotic resistant germs. I think that's all we really care about. Antibiotics are what we use to treat infections, we don't care if bacteria become resistant to alcohol or other disinfectant methods.
Bacteriophages have no ability to infect humans. In fact, they can only infect a specific kind of bacteria; it won't kill other bacteria. Which is really good because if it was so easy for viruses to jump from one species to another, we'd all be dead already. Phage literally means "to eat". Once all the bacteria are dead, their food will be gone and the bacteriophages will die off.
Phages could be very useful as another line of defense against bacteria. I know if I was infected with antibiotic resistant bacteria and was going to die, having more options available would be more than welcome. Not only that but viruses in general are going to be very useful in the future from gene therapy (which might just cure HIV), to attacking cancer cells (talk about swallowing a spider what with chemo and radiation; viruses would be far more targeted and elegant).
