COVID-19, mass testing and the utility of wastewater epidemiology

In a recent study, researchers developed a methodology to detect SARS-CoV-2 RNA in wastewater with the potential for finding an association between the wastewater treatment plant (WWTP) SARS-CoV-2 influent viral RNA load and COVID-19 cases in the community. This study indicates that a national scale wastewater-based epidemiology can play a role in COVID-19 surveillance.

SARS-CoV-2 genome mutations display convergent evolution indicating strong adaptive advantages

A recent report by a team of researchers focused on the extent of convergent evolution in the SARS-CoV-2 spike (S) protein. The report confirms that top SARS-CoV-2 lineages of concern have the most convergent spike protein mutations. This indicates their fundamental adaptive advantage.

SARS-CoV-2 variants partially escape humoral immunity, but not T cells responses, study finds

Researchers at the Department of Viroscience, Erasmus MC, National Institute for Public Health and the Environment, Amsterdam UMC, and the Weill Medical College of Cornell University studied humoral and cellular immune responses to the wild type SARS-CoV-2, the B.1.1.7 variant (U.K. variant) and the B.1.351 variant (South African variant) in health care workers vaccinated with the BNT162b2 (Pfizer-BioNTech) mRNA vaccine.

Harnessing DNA’s properties to craft “‘topologically tunable” DNA-based materials

While DNA is often idealized as the "molecule of life", it is also a highly sophisticated polymer that can be used for next-generation materials. Beyond the fact that it can store information, further fascinating aspects of DNA are its geometric and topological properties, such as knotting and super-coiling.

New study may help improve stem cell transplantation, lead to better drugs

Your immune system is always busy fighting incoming threats. It consists of a system of cells, and when there is a shortage of cells, it affects the performance of the immune system.

Genomic study identifies marked differences between two halves of the hippocampus

A study of gene activity in the brain's hippocampus, led by UT Southwestern researchers, has identified marked differences between the region's anterior and posterior portions. The findings, published today in Neuron, could shed light on a variety of brain disorders that involve the hippocampus and may eventually help lead to new, targeted treatments.

New SARS-CoV-2 lineages continue to threaten pandemic control in England, suggests genomic study

A new study shows the pattern of the rise of various strains in the UK, as shown by the data collected by the COVID-19 Genomics UK Consortium. This allows the rise and fall of 62 different viral lineages to be traced through over 300 local authorities from September 2020 to April 2021.

Loss of gut epithelial barrier responsible for COVID-19-related MIS-C in children, suggests study

A new paper in the Journal of Clinical Investigation reports that this condition is due to damage to the gut, mediated by a decrease in the protein called zonulin, which is responsible for the integrity of the gut epithelial barrier. Reduced zonulin levels are found in several inflammatory and autoimmune conditions.
