NewsStudy reveals how young children’s immune systems tame SARS-CoV-2
A study of infants and young children found those who acquired SARS-CoV-2 had a strong, sustained antibody response to the virus and high levels of inflammatory proteins in the nose but not in the blood.

NewsCoronavirus vaccination reveals that body builds immune memory in organs
A study of the mRNA coronavirus vaccines reveals that the human body builds local immune memory in various organs. The immune memory cells are more numerous in the organs than in the blood and have enhanced antiviral defense functions.

NewsAI tool can help forecast viral outbreaks
A new AI tool called EVEscape uses evolutionary and biological information to predict how a virus could change to escape the immune syste, and successfully predicted the most concerning new variants that occurred during the COVID-19 pandemic.

NewsVulnerability to different COVID-19 mutations depends on previous infections and vaccination
A person’s immune response to variants of SARS-CoV-2 depends on their previous exposure – and differences in the focus of immune responses will help scientists understand how to optimise vaccines in the future to provide broad protection.

NewsStudy IDs six drugs that can be repurposed for treatment of toxoplasmosis
Brazilian researchers screened 160 compounds known to be effective against SARS-CoV-2 and identified those that also act against the protozoan parasite Toxoplasma gondii.

NewsCovid-19 protein primes RNA synthesis in human cells
Researchers have shown for the first time that it is the human protein SND1 which works together with the viral protein NSP9 to stimulate the SARS-CoV-2 virus’s genetic replication program in infected cells.

NewsSugar binding to spike protein is key to coronavirus cell entry
A study uses powerful microscopes and computer simulations to reveal how a tiny sugar molecule binds to a human coronavirus spike and triggers exposure of components that are required to invade the host cell.
-
NewsPortable laboratory devices can detect SARS-CoV-2
A new study has demonstrated rapid and sensitive on-site detection of SARS-CoV-2 RNA from environmental surfaces using a portable laboratory device.

NewsScientists discover alternative base modification for mRNA therapeutics
Researchers have incorporated a newly discovered base, called base Z, into mRNA to create Z-mRNA that has improved translational capacity, decreased cytotoxicity and drastically reduced immunogenicity compared to unmodified mRNA.

NewsDoes COVID-19 or COVID-19 vaccination worsen migraines?
New research indicates that COVID-19 and COVID-19 vaccination have negligible effects on migraine severity.

NewsVersatile vaccine candidate fights measles, mumps and Covid
Altered measles and mumps viruses could be used as a platform to create a trivalent COVID-19 vaccine that triggers immunity to multiple variant strains of the SARS-CoV-2 virus, new research in animals suggests. The study builds upon previous studies that involved inserting a highly stable segment of ...

NewsNobel Prize goes to researchers whose discoveries paved way for mRNA vaccines
The 2023 Nobel Prize in Physiology or Medicine has been awarded to Katalin Karikó and Drew Weissman for their discoveries concerning nucleoside base modifications that enabled the development of effective mRNA vaccines against COVID-19.

NewsCovid-linked sepsis more common and deadly than previously thought
New research suggests that the virus responsible for COVID-19 was a more common and deadly cause of sepsis during the initial period of the pandemic than previously assumed.
-
NewsNew coronavirus-capturing material could transform the face mask
Researchers have developed a new material that captures coronavirus particles and could transform the efficiency of face masks.
-
NewsContagious omicron strain replicates early in infection
New research used engineered mice to compare SARS-COV-2 omicron subvariants and found one of them – BA.5 – was more virulent likely due to its ability to rapidly replicate early during infection.
-
NewsNew vaccine technology could protect from future viruses and variants
Studies of a ‘future-proof’ vaccine candidate have shown that just one antigen can be modified to provide a broadly protective immune response in animals.
-
NewsAntiviral drug linked to SARS-CoV-2 mutations
Researchers have uncovered a link between an antiviral drug for COVID-19 infections called molnupiravir and a pattern of mutations in the SARS-CoV-2 virus.
-
NewsCOVID-19 could hold key to spotting viruses with pandemic potential
Certain SARS-CoV-2 variants of concern are evolving to do a better job of shutting down human innate immune responses, according to new research.

CareersIgnoring the rise of anti-science could usher back once-deadly diseases
As a wave of anti-science sentiment sweeps the globe, scientists need to speak up, says paediatric vaccine scientist Dr Peter Hotez in an interview with The Microbiologist as he launches his new book.

NewsScientists developing field test to detect Covid virus in dozens of host species
Purdue University has received $2.7 million in federal funding to develop a field test that can measure and predict the spread of SARS-CoV-2, the virus that causes COVID-19, in a wide range of wildlife and farm animals.
