NewsAntibiotics combat the gut bacteria that contribute to the pathogenesis of COVID-19
New research indicates that antibiotics can effectively target bacteria in the gut that harbor the virus that causes COVID-19 and produce toxin-like peptides that contribute to COVID-19-related symptoms. In the study, which involved 211 participants and was published in the Journal of Medical Virology, individuals who received ...

NewsNew bioengineered protein design shows promise in fighting COVID-19
Researchers have designed a novel protein capable of binding to the spike proteins found on the surface of the coronavirus, allowing them identify and recognize the virus for diagnostic purposes, and to hinder its ability to infect human cells.

NewsLong COVID ‘indistinguishable’ from other post-viral syndromes a year after infection
A team of scientists, including Queensland’s Chief Health Officer, say it is time to stop using terms like ‘long COVID’ as they wrongly imply there is something unique and exceptional about longer term symptoms associated with the virus.

NewsNew nasal vaccine platform helps clear COVID-19 infections in an animal model
Researchers demonstrate proof-of-principle of a protein-based platform, called SpyCage, that could eventually help to prevent infection and transmission of respiratory viruses, like SARS-CoV-2.

NewsStudy reveals low COVID-19 transmission rate from mothers to newborns
COVID-19 vaccination reduces risks of severe outcomes in pregnant women, who show fewer harmful effects from the Omicron variant, a study shows. It also reveals that COVID-19 transmission from mothers to their newborns is low.

NewsCOVID-19 had greater impact on life expectancy than previously known, but child mortality rates continued to decline
A new study reveals the staggeringly high mortality from the COVID-19 pandemic within and across countries. Places such as Mexico City, Peru, and Bolivia had some of the largest drops in life expectancy from 2019 to 2021.

NewsVaccine monitoring crucial as SARS-CoV-2 variants continue to evolve
Researchers compared the newer monovalent COVID vaccine, which specifically targets the XBB variant of Omicron, with older bivalent vaccines containing a mix of an Omicron variant and the original strain of COVID-19.

NewsMathematicians use AI to identify emerging COVID-19 variants
Scientists have developed an AI framework that can identify and track new and concerning COVID-19 variants and could help with other infections in the future.

NewsCOVID vaccines are safe for pregnant women and babies
The COVID vaccine is safe to administer during pregnancy, reports a new study in an important finding on the safety of the vaccine in infants – despite widespread fear and misinformation.

NewsCOVID-19 virus can stay in the body more than a year after infection
The COVID-19 virus can persist in the blood and tissue of patients for more than a year after the acute phase of the illness has ended, according to new research that offers potential clues to why some people develop long COVID.

NewsFibrinolytic biomarkers for identifying patients at risk of severe COVID-19
Researchers identify associations between proteins involved in fibrinolysis and the development of acute respiratory distress syndrome.
-
NewsScientists show how COVID mRNA vaccines reshape immune memory after each dose
Researchers show that T cells can reshape their memory and maintain diversity against different COVID variants in response to successive mRNA vaccinations.
-
NewsVaccinated people had lower risk of severe COVID-19 outcomes
Among people who had COVID-19, those who previously received the latest vaccine had a lower risk of having a severe outcome than those who had not, according to new research.

NewsBreastfeeding after COVID-19 booster can give babies antibodies
Lactating mothers who get the COVID-19 booster pass along the antibodies to their children via their breast milk – and potentially protect babies too young to receive the vaccine.

NewsResearchers investigate immune response of a man who received 217 Covid vaccinations
Researchers who examined a man who has received more than 200 vaccinations against Covid-19 say there were no negative impacts on his immune system.

NewsStudy shows new class of antivirals that works against SARS-CoV-2
Researchers have uncovered a new class of drugs with the potential to prevent or treat infections in a future viral outbreak.

NewsProtective human monoclonal antibody targets a conserved site of spike glycoprotein of SARS-CoV-2 Omicron variants
Scientists report that mAb-39 greatly improved the neutralizing activity of anti-RBD antibody, the same type of EUA therapeutic monoclonal antibodies, against the highly neutralization-resistant Omicron variants.

NewsResearchers reveal how the SARS-CoV-2 virus acquires its spherical shape
Researchers report that when the M protein, which is adjacent to the spike protein on SARS-CoV-2, gets lodged in the membrane, it coaxes the membrane to curve by locally reducing the membrane thickness.

NewsStudy reveals potential flaw in operating room ventilation that increases risk of Covid infection
Simple modifications to ventilation systems improve airflow, making operations safer for both patients and surgical teams.

NewsNew disease testing component facilitates lower-cost diagnostics
Biomedical researchers have developed a new, less expensive way to detect nuclease digestion – one of the critical steps in many nucleic acid sensing applications, such as those used to identify COVID-19 and other infectious diseases.
