Exposure to toxic metals like cadmium has been associated with adverse pregnancy outcomes such as miscarriage, preterm birth and low birth weight. Because these effects are difficult and ethically challenging to study directly in pregnant women, how such exposures affect pregnancy has remained poorly understood.

Climate shapes microbial nitrogen pump in forests, not in farmlands
Microbes build a long-lived nitrogen reservoir in soil from the remains of dead bacteria and fungi, which cling to minerals and resist decay. The microbial nitrogen pump turns nitrogen taken up by living microbes into this persistent pool, and microbial nitrogen use efficiency (N
