mRNA COVID-19 vaccine protection wanes after six months: a wide-scale study of the population of Qatar

In a paper recently uploaded to the preprint server medRxiv* by Chemaitelly et al. (August 27, 2021), the long-term effectiveness of the mRNA vaccines is analyzed amongst the Qatar population. The study observed waning protection against infection around six months post-vaccination but lasting protection from death and hospitalization.

Research reveals the impact of nicotine-containing e-cigarettes on the body

Using e-cigarettes containing nicotine causes an immediate increase in the formation of blood clots and a deterioration in the ability of small blood vessels to expand and dilate, as well as raised heart rate and blood pressure, according to research presented at the European Respiratory Society International Congress.

Using infodemiology to understand symptoms of SARS-CoV-2 Lambda variant

A new variant (lineage C.37) initially identified in Lima, Peru, has since been classified as “Lambda” by the World Health Organization (WHO). The lambda variant was classified in June 2021 by the WHO as a “variant of interest.”

Using an internal cognitive map to solve abstract problems

How do we make decisions about a situation we have not encountered before? New work from the Center for Mind and Brain at the University of California, Davis, shows that we can solve abstract problems in the same way that we can find a novel route between two known locations - by using an internal cognitive map.
