NewsStudy tracks Atlantic Meridional Overturning Circulation using benthic foraminifera
Scientists investigated how the weakening of Atlantic Meridional Overturning Circulation is connected to the ventilation of the shallow ocean. Using benthic foraminifera, the team was able to reconstruct changes in the oxygen content of the oxygen-minimum zone over 27,000 years.

NewsVaccination could mitigate climate-driven disruptions to malaria control
Tropical cyclones in Madagascar lead to sharp spikes in malaria infections – particularly in children – due to interruptions in control efforts, according to a new study. However, newly introduced long-lasting vaccines can help to mitigate these gaps.
