The stable isotopic δ18O and δ13C composition of foraminiferal shell calcite varies as a function of many factors including temperature and salinity. In order to understand and interpret the variations in the isotopic composition of foraminiferal shell calcite, research has been recently focused on the role of the "vital effects’. Our examination of the lamella structure of several recent planktonic foraminifera indicates that the secretion of sequential lamellae results in multiple lamillae on earlier chambers and a single lamella on the final chamber. We used a very simple procedure to separate the individual whole test of foraminifera into several chambers and measured the isotopic composition of each growth stage chamber. The results indicate that the stable isotopic composition (carbon and oxy -gen), particukrly that of the last two chambers, of the foraminiferal test varies as a function of the individual growing process.

Three research papers were published recently to compare the virological properties of the Omicron variant with the earlier variants of concern(VOC).1,2,3 The SARS-CoV-2 B.1.1.529 variant,Omicron,was first detected in South Africa in October 2021 and has spread rapidly;within three months,it appeared in more than 87 countries.4 During the surveillance of the epidemiological data and mutations of earlier COVID-19 variants and Omicron,significant differences were revealed mainly in the reproduction rate and hospitalization.
