Here the authors investigate the effects of plastic pollutants on terrestrial life. Specifically they look at the growth of Brassica rapa and determine that phosphate levels have the most negative impact on growth.

Hydrogen sulfide is toxic at high concentrations, but at low concentrations may be helpful for plant growth. This study characterizes the effect of hydrogen sulfide exposure on leafy plant growth. Bok choy hearts were grown in the presence of hydrogen sulfide, and measured for new leaf growth and flowering.

In this study, the impact of thermal effects on the orbit of an asteroid is investigated. This included determining if the asteroid's orbit would push into a region devoid of asteroids due to the gravitational pull of Jupiter.
