NewsAncestral mitoviruses discovered in mycorrhizal fungi
A new group of mitochondrial viruses confined to the arbuscular mycorrhizal fungi Glomeromycotina may represent an ancestral lineage of mitoviruses.

NewsPostal HPV kits boost cervical screening uptake
At-home high-risk human papillomavirus (hrHPV) sampling kits can help increase cervical cancer screening among under-screened women from low-income backgrounds, according to findings from a US-based clinical trial.

NewsMeet Ginger: the gene-edited calf resistant to BVDV
Scientists introduce Ginger, the first gene-edited calf with reduced susceptibility to a major viral pathogen.
-
NewsProtein may pave way to eliminating HIV latency
Researchers have identified and characterized Schlafen 12 (SLFN 12) as a novel HIV restriction factor that shuts down viral protein production and helps virus-infected cells to escape from anti-HIV therapy and immune responses.
-
NewsCRISPR-based drug candidate targets the microbiome
Scientists have engineered the first published CRISPR-based candidate for a drug - a combination of phages - that targets E. coli directly and leaves the microbiome intact.
-
NewsViruses may disrupt carbon cycle in warming world
Scientists describe many different ways that increasing temperatures could affect viruses and their microbial hosts, changes that could ultimately affect the responses of whole ecosystems to warming.

NewsMeasles surge sparks UK government vaccine call
The UK government has urged parents to make sure their children’s MMR vaccine is up to date following a rise of measles cases.
-
NewsBlack eyes in seabirds indicates bird flu survival
A new study has discovered evidence that Northern Gannets can recover from Highly Pathogenic Avian Influenza (HPAI) H5N1, with black irises indicating a previous infection.
-
NewsLiverpool begins first human trial of Zika vaccine
The first participant has received a dose of a new Zika virus vaccine being trialled by the University of Liverpool.
-
NewsHIV targeted with novel dual gene-editing approach
Gene-editing therapy aimed at two targets – HIV-1, the virus that causes AIDS, and CCR5, the co-receptor that helps the virus get into cells – can effectively eliminate HIV infection, new research shows.
-
NewsVietnam hotspot IDed for viral disease emergence
Bat roosting sites, guano harvesting, and pig farms, all in close proximity, coupled with a high diversity of circulating coronaviruses indicates a high risk of CoV spillover, One Health surveillance reveals.
-
NewsSystem targets and degrades viral RNA to treat Covid infection
Researchers have developed a system that directly targets and degrades the viral RNA genome, reducing infection in mice. The method could be adapted to fight off many viruses, as well as treat various diseases.
-
NewsMechanisms may be used to lure viruses into a trap
Researchers have described previously unknown mechanisms of viral penetration by the Influenza A and Ebola viruses, which could lead to new approaches to prevent infections.
-
NewsStudy of Covid contamination of shipping materials may yield guidance for goods transportation
Researchers investigating how environmental factors affect the persistence of two different, highly transmissible Omicron variants on shipping materials find that viability depends on the type of surface, the temperature and the original viral concentration.
-
NewsPhylogenetic analysis reveals the lessons of previous bird flu outbreaks
Researchers have confirmed that the H7N9 virus was likely circulating in poultry for several months before being discovered in both poultry markets and humans and that more poultry markets may have been affected than previously believed.
-
NewsFirst human respiratory organoid culture system reveals secret of Omicron’s transmissibility
Researchers have established the first human respiratory organoid culture system and unveiled a novel mechanism for the high transmissibility of SARS-CoV-2 Omicron variant.
-
NewsPlankton trawl reveals new viruses related to both giant viruses and herpes viruses
Metagenomic data from Tara Oceans on marine plankton has enabled the discovery of a major group of DNA viruses found abundantly from the equator to the poles: mirusviruses.
-
NewsEconomic growth alone is not enough to eliminate rabies, research finds
Economic growth alone may not be enough to deliver the internationally agreed target to end human deaths from dog mediated rabies, according to new research.
-
NewsObese pregnant women infected by zika virus have impaired immune response
Researchers have shown for the first time that gestational obesity associated with infection by zika virus influences the placenta’s antiviral response, weakening the organ’s capacity to attack the pathogen and protect the foetus.
-
NewsInfectious SARS-CoV-2 isolated from hospital air samples
Scientists have succeeded in isolating infectious particles of the SARS-CoV-2 virus from air samples collected from hospital rooms of COVID-19 patients and kept frozen for more than a year, a new study shows.
