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.
-
NewsFirst rapid test for mpox can be tailored for other emerging diseases
The first rapid test for mpox has been developed - the selective molecular sensor can detect the virus within minutes, without the use of any high-end instrumental techniques.
-
NewsPolymer discovery stops bacterial virus contamination
A new discovery by researchers at the University of Warwick could help stop bacteria being contaminated with viruses, reducing disruption and decreasing costs in industry and research.
-
NewsRisk of a measles outbreak in London is significant, say researchers
Doctors in London have been urged to be vigilant for symptoms of measles as researchers warn that the risk of outbreaks in the city is significant.
-
NewsSpread of COVID-19 in households linked to virus on hands and surfaces, say researchers
A new Imperial College London-led study provides the first empirical evidence for transmission of SARS-CoV-2 via people’s hands and frequently touched household surfaces.
-
NewsOmicron appears more deadly than seasonal influenza, study suggests
Adults hospitalised with the SARS-CoV-2 Omicron variant have a higher death rate than those hospitalised with seasonal influenza, even though Omicron is considered less virulent with lower case fatality rates than the delta and alpha strains, new research being presented at ECCMID suggests.
-
NewsMask rule in hospitals may have little impact on COVID-19 transmission during Omicron wave
A study in large London hospital during first 10 months of Omicron activity suggests the real-world benefit of mask-wearing in isolation is likely to be modest, according to new research being presented at this year’s ECCMID.
-
NewsResearchers reveal why viruses like SARS-CoV-2 can reinfect hosts and evade immune response
Using a tool called VirScan, Brigham investigators found that people produced shared antibody responses to certain regions of the virus, likely leading to selective pressure and new variants that can repeatedly escape detection by prior immunity.
-
NewsMicrobes that “eat together” may benefit from a shared immunological memory
A new study examines viruses that infect microbes in the deep sea and finds evidence that viruses interact with a far more diverse set of hosts than was previously thought.
-
NewsGene scissors used successfully in the laboratory against HIV-related virus
Researchers have provided initial proof of concept for a potential therapeutic approach targeting HTLV-1, a retrovirus that triggers aggressive forms of leukemia or an incurable spinal cord disease that leads to paralysis.
-
NewsMosquito saliva can weaken body’s defenses against deadly dengue viruses
The saliva of mosquitoes infected with dengue viruses contains a substance that thwarts the human immune system and makes it easier for people to become infected with these potentially deadly viruses, new research reveals.
