I know biology and many other STEM stipends are very low.

As someone in a business field with a very high stipend (32k), I am also feeling the pinch. My wife and I keep a relatively strict budget and I track with YNAB, and gas alone is pretty damaging to our spare income. And I am lucky to be at an institution in a college town with a relatively low cost of living. I don't know how my peers in cities like Boston do it.

Have you considered a used bicycle for transportation? Hobbyists refurbish old steel frames that last forever and work as well as they did on day one, and they're usually $100-$300 depending on your desired comfort level.
