SARS-CoV-2 and pepper mild mottle virus RNA highly persistent in wastewater solids

A new study from the United States (US) investigates the persistence (lifetime) of viral ribonucleic acid (RNA) under different ambient conditions within wastewater infrastructure to understand how it impacts RNA measurements and the related wastewater epidemiology.

A common cold may boost the immune system against COVID-19

A recent groundbreaking research paper published in the journal Nature Communications reveals the association of circulating SARS-CoV-2-specific T cells at exposure with lack of infection – implying the protective role for cross-reactive immune T cells in coronavirus disease 2019 (COVID-19) and opening the door for second-generation vaccines that could circumvent spike-antibody immune escape variants.

New technique could allow more diseases to be safely treated by nanomedicine

Researchers at Penn Medicine have discovered a new, more effective method of preventing the body's own proteins from treating nanomedicines like foreign invaders, by covering the nanoparticles with a coating to suppress the immune response that dampens the therapy's effectiveness.

Telemedicine at Johns Hopkins Medicine enables a stroke patient to be treated with high level of care

A patient believed to have suffered a stroke typically gets transported to the nearest emergency room for tests to determine the best course of action. Telemedicine at Johns Hopkins Medicine enabled one patient to have her stroke diagnosed and a treatment plan set up without ever stepping foot in a hospital.

Monitoring the presence of enteric pathogens in imported seafood

To monitor the presence of enteric pathogens in imported seafood, the authors of this paper collected a total of 140 seafood samples imported from eight overseas countries from Beijing, Dalian, Shanghai, Guangzhou, and Wuhan seafood markets from June to November 2019.

Danish household study shows COVID vaccinates reduce susceptibility and transmissibility

A new study discusses the effect of vaccines against COVID-19 on the transmissibility and susceptibility of vaccine recipients to SARS-CoV-2.

Simple health assessment could significantly reduce the global burden of COPD

The global burden of Chronic Obstructive Pulmonary Disease (COPD), a group of common lung conditions that affects more than 300 million people, could be significantly reduced with a simple health assessment, concludes a large-scale international study led by UCL researchers.

New passive air sampler clip can help assess personal exposure to SARS-CoV-2

Masks, social distancing, proper hygiene and ventilation can help reduce the transmission of COVID-19 in public places, but even with these measures, scientists have detected airborne SARS-CoV-2 in indoor settings.

Third dose of mRNA COVID vaccine induces strong immunity in older adults

A new study describes the beneficial effects of a third dose of the COVID-19 mRNA vaccine in strengthening immunity among older adults.

Hemp compounds show ability to prevent the entry of SARS-CoV-2 into cells

Hemp compounds identified by Oregon State University research via a chemical screening technique invented at OSU show the ability to prevent the virus that causes COVID-19 from entering human cells.

International study offers a clearer picture of COVID-19's impact on children

A new international study offers a clearer picture of the impact of COVID-19 infection and the risk of severe outcomes on young people around the world.

Impact of post-exposure BNT162b2 prophylaxis against SARS-CoV-2 infections

In a new study, researchers determined evidence for post-exposure vaccination in reducing the mortality rate of COVID-19 and concluded that post-exposure prophylaxis successfully decreased SARS-CoV-2-associated death rates.

Withdrawing steroid treatment found to boost SARS-CoV-2 vaccine-induced immunity in kidney transplant recipients

In a new study, a team of researchers investigated the impact of the fourth dose of a vaccine against COVID-19 in kidney transplant recipients, who had not mounted a humoral immune response to three doses of vaccine.

VarLOCK approach for rapid detection of SARS-CoV-2 variants of concern and wastewater monitoring

A recent study discussed the expansion of the SARS-CoV-2 CRISPR-Cas detection technology (SHERLOCK) into Variant-specific SHERLOCK (VarLOCK) assays to accurately differentiate between the newly emerging SARS-CoV-2 variants of concern.

Unraveling the early host-immune response to SARS-CoV-2 in mild COVID-19 infections

In a new study, researchers determined the early immune response to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) during mild coronavirus disease 2019 (COVID-19) in rhesus macaques.

Exploring the kinetics of SARS-CoV-2 Marseille-4 variant

In a new study, researchers determined the nature and dynamics of mutations associated with the SARS-CoV-2 French Marseille-4 variant during 10 months from its onset, and concluded that the heterogenicity associated with a SARS-CoV-2 lineage can possibly predict the end of an outbreak.
