What can scientists do to deal with the problem of antibiotic resistance?

Antibiotic resistance is caused by the over usage of prescriptions/medicinal remedies. 

Scientists can't really do anything. It chiefly relies on the individual since resistance occurs when an individual repeatedly takes a dosage when symptoms aren't that serious. However, bans placed on certain remedies that are known to be able to be resisted would help deal with the problem of antibiotic resistance. Another help would be the creation of an antibiotic that kills pathogens. Doing so would cause resistance to be rare or even non existent in some cases.
