drugs stories

Drugs are just molecules that are small enough to interact with the cells in your body. We've discovered a lot of them: 67 million unique substances, according to the American Chemical Society. But this is only about one tenth of one percent of the potential drugs out there, so we've definitely got some work to do.
Ever since the accidental discovery of penicillin, we've had ways of being able to deal with bacterial infections. With viral infections, like when you get a cold, all we can really do is suck it up and treat the symptoms, but a new type of drug may be able to tackle any virus, even the ones we haven't met yet.
