Getting inspiration from science
Science is one of the cornerstones of our existence. So are your characters scientific? Do they f’ing love science? And even if they don’t, it can still inform what they say and do.
First of all, there is an enormous amount of inherent drama in trying to discover a cure for a disease. However, sometimes things go another way, where a seemingly serious breakthrough ends up having a rather different application. So consider minoxidil, which is used to treat baldness. It was originally developed to be a drug to treat high blood pressure.
And research, with all its successes and failures, can spark drama.
Chemistry and Physics
So chemist characters can do everything from creating potions on the edge of magic to working in pharmacies. And your physicist characters can study the cosmos. Or maybe they build nuclear weapons, and experience all sorts of doubts and moral crises due to that. Furthermore, any of these characters can teach at the high school or collegiate (or graduate school) levels.
Biology and Geology
Maybe a biologist character could unleash a plague or study alien creatures. And a geologist character could warn of an impending volcano eruption (this would be a vulcanologist, actually), or maybe help find fossil fuels.
Beyond finding cures, doctors also handle people at their most vulnerable. And they see the weak, the sick, the dying, and the naked. So some physicians find humor in the absurd, like in M*A*S*H. Psychiatrists can work with the insane or just the troubled. And that can spill over into marriage counseling, or helping people figure out how to come out of the closet.
So whether your characters are blinded with science or just need to get a sprain treated, scientific observations and pursuits can often inspire great writing.
