NewsNasal swab tests predict COVID-19 disease severity
New reserach is providing a more precise prediction of COVID-19 severity that can be found by looking at autoantibodies in the nasal cavity, leading to more personalized treatment plans.
-
NewsStudy reveals stubborn mistrust in COVID-19 vaccine science
A new study sheds light on public trust in COVID-19 vaccine science and its impact on vaccine acceptance in the United States from 2021 to 2023, finding that around one-third of respondents expressed mistrust in the science behind COVID-19 vaccines.
-
NewsEffective wastewater surveillance methods for monitoring COVID-19 infection trends
A research team identified appropriate investigation methods for wastewater surveillance to accurately monitor regional COVID-19 infection trends.
-
NewsRepeated COVID vaccines enhance mucosal immunity against the virus
New work has found that repeated Covid-19 vaccinations lead to the presence of mucosal antibodies, for example, inside the nose.
-
NewsNovel antibody platform tackles viral mutations
Scientists have developed an innovative antibody platform aimed at tackling one of the greatest challenges in treating rapidly evolving viruses like SARS-CoV-2: their ability to mutate and evade existing vaccines and therapies.
-
NewsFloor swabbing could help prevent COVID-19 outbreaks in hospitals
In two Ontario hospitals, high levels of SARS-CoV-2 on floors correlated with COVID-19 cases among healthcare workers and patients, suggesting floor swabbing as a potential method to prevent outbreaks.
-
NewsStudy uncovers how Covid-19 is so good at defeating the innate immune response
The novel coronavirus SARS-CoV-2 has an enzyme that can counteract a cell’s innate defense mechanism against viruses, explaining why it is more infectious than the previous SARS and MERS-causing viruses.
-
NewsCOVID study reveals virus-induced inflammation during pregnancy, redefines vertical transmission
A protein made by SARS-CoV-2 can pass through the placenta and cause serious inflammatory immune responses in the fetus for 66% of pregnancies.
-
NewsState-of-the-art centre for patients with complex conditions including Lyme disease and long COVID
New state-of-the-art US centre will support patients recovering from complex chronic illnesses such as long Lyme disease and long COVID.
-
NewsViral messaging can deliver lessons on how infectious diseases spread
A new study explores a hybrid approach to understanding social networks that involves inferring not just social contacts but also the rules that govern how contagion and information spread.
-
NewsScientists discover series of SARS-CoV-2 mpro inhibitors for potential COVID-19 treatments
New research has identified a novel series of SARS-CoV-2 Mpro inhibitors that may lead to potential new COVID-19 treatments that, according to preclinical testing, effectively inhibits COVID-19 and synergizes with existing anti-COVID therapies.
-
NewsStudy finds persistent infection could explain long COVID in some people
Researchers found people with wide-ranging long COVID symptoms were twice as likely to have SARS-CoV-2 proteins in their blood, compared to those without long COVID symptoms.
-
NewsResearchers confront new US and global challenges in vaccinations of adults
Decreasing vaccination rates now threaten the huge beneficial impacts of vaccinations in the U.S. and globally. Researchers discuss the barriers including increasing vaccine hesitancy and new clinical and public health challenges in vaccinations of U.S. adults.
-
NewsPeptide acts as molecular shield to prevent SARS-CoV-2 from infecting cells
The synthetic peptide was inspired by ACE2, the protein to which the virus that causes COVID-19 binds to invade human cells. The results point to a route for the development of novel antivirals.
-
NewsNew mouse models offer valuable window into COVID-19 infection
Scientists have developed six lines of humanized mice that can serve as valuable models for studying human cases of COVID-19 because their cells were engineered to include two important human molecules that are involved in infection of human cells.
-
NewsHigh-throughput modular click chemistry synthesis of catechol derivatives to target Covid protease
Researchers performed high-throughput synthesis of catechol derivatives from the bioactive catechol-terminal alkyne scaffold A4, by using modular click chemistry, in a bid to target the Covid virus’s 3C-like protease (3CLpro).
-
NewsCould a bout of COVID protect you from a severe case of flu?
More than 200 viruses can infect and cause disease in humans; most of us will be infected by several over the course of a lifetime. Does an encounter with one virus influence how your immune system responds to a different one?
