Exposure to airborne SARS-CoV-2 in four hospital wards and ICUs of Cyprus. A detailed study accounting for day-to-day operations and aerosol generating procedures

Heliyon, 2023
In any infectious disease, understanding the modes of transmission is key to selecting effective public health measures. In the case of COVID-19 spread, the strictness of the imposed measures outlined the lack of understanding on how SARS-CoV-2 transmits,

Unexpectedly high ultrafine aerosol concentrations above East Antarctic sea ice [PDF]

Atmospheric Chemistry and Physics, 2016
Better characterisation of aerosol processes in pristine, natural environments, such as Antarctica, have recently been shown to lead to the largest reduction in uncertainties in our understanding of radiative forcing.

Comparative genomics highlight the importance of lineage-specific gene families in evolutionary divergence of the coral genus, Montipora

BMC Ecology and Evolution, 2022
Background Scleractinian corals of the genus Montipora (Anthozoa, Cnidaria) possess some unusual biological traits, such as vertical transmission of algal symbionts; however, the genetic bases for those traits remain unknown.
