NewsNew two-step flu vaccine strategy shows promise in pig model
A new, two-step flu vaccination strategy that pairs intramuscular injection of a viral vectored flu vaccine with nasal spray administration of a novel attenuated live flu virus appears to be safe and effective in pigs.

NewsPrioritizing the elderly for COVID-19 boosters reduces overall deaths
When COVID-19 booster vaccines are in short supply, prioritizing the elderly over other age groups for booster vaccination results in the lowest loss of life, reports a new study.

NewsInfected bacteria fight back with ‘hidden’ genes that halt cell growth, slow viral spread
Researchers have uncovered a surprising way bacteria defend themselves: when a bacterium is infected, bacterial enzymes that copy genetic information from RNA into DNA synthesize genes whose protein products help shut down cell growth.

NewsMarine algae use massive enzymes of unprecedented size to biosynthesize fish-killing toxins
Marine algae Prymnesium parvum use massive enzymes dubbed PKZILLAs – some of the largest proteins ever to be identified in nature – to make large and complex prymnesin neurotoxins responsible for mass fish kills during harmful algal blooms worldwide.

NewsAmid Covid-19 summer wave, new WHO/Europe study confirms the lifesaving impact of vaccines
From the time of their introduction in December 2020 through to March 2023, COVID-19 vaccines reduced deaths due to the pandemic by at least 59%, saving more than 1.6 million lives in the WHO European Region.

NewsLens-free fluorescence instrument detects deadly microorganisms in drinking water
A new approach promises low-cost, real-time water quality monitoring for developing countries, disaster areas and rapid testing needs at events like the Paris Olympics.
-
NewsAncient viral elements in RNA kickstart bone repair
A common transposable element - a DNA fragment originating from an ancient virus - plays a positive role in triggering bone repair, with potential applications in treating osteoporosis and many other diseases.

NewsMulti-omics strategy reveals how insect parasite fungus ameliorates sepsis-associated acute kidney injury
Scientists have found that Cordyceps sinensis significantly ameliorates renal injury and inflammation in sepsis-associated acute kidney injury (S-AKI) by regulating mitochondrial energy metabolism and macrophage polarization.
-
NewsNasal microbiome: friendly pirates deprive multi-resistant bugs of iron
A new study reveals that whether dangerous staphylococci survive in the nose depends on what other bacteria are present – and how they obtain iron.
-
NewsReport on Great Barrier Reef shows coral cover was increasing before onset of serious bleaching, cyclones
Coral cover has increased in all three regions on the Great Barrier Reef and is at regional highs in two of the three regions according to a report by the Australian Institute of Marine Science (AIMS) - but the results come with a note of caution.
-
NewsDisaster plant pathology: solutions to combat agricultural threats from disasters
Scientists have published a multidisciplinary perspective on current threats and solutions to plant health and food security, encompassing the risk from environmental factors such as climate change, while also including factors such as political instability and war.

NewsSaliva indicates severity of recurrent respiratory infections in children
A saliva test can more accurately indicate the severity of recurrent respiratory infections in children than the standard blood test. If saliva contains too few broadly protective antibodies, a child is more likely to suffer from pneumonia episodes.
-
NewsResearchers create new device for on-the-spot water testing
Applied Microbiology International expert Dr Zina Alfahl and colleague Dr Louise O’Connor have developed a new, portable technology for on-the-spot testing of water quality to detect one of the most dangerous types of bacteria.
-
NewsFungi elude antifungal treatments by restructuring cell walls
A new multi-institutional study has characterized how fungi adapt to restructure their cell walls, effectively thwarting current antifungal medications. This new information opens opportunities to devise more effective use of antifungal drugs.
-
NewsDo smells prime our gut to fight off infection?
A recent study shows that the nematode C. elegans reacts to the odor of pathogenic bacteria by preparing its intestinal cells to withstand a potential onslaught.
-
NewsResearchers seek novel approach to study aerosols implicated in respiratory virus transmission
The team is developing and applying new techniques to characterize respiratory aerosols to help better understand the physical basis for environmental impact on transmission rates.
-
NewsMicrobes and their interactions are focus of major international meeting
One of the academic world’s largest international meetings addressing topics in microbial ecology, the 19th International Symposium on Microbial Ecology (ISME), will take place in Cape Town, South Africa in August
-
NewsGlimpse into the nanoworld: microscope reveals tiniest cell processes
Researchers have succeeded in developing a microscope with resolutions better than five nanometres (five billionths of a metre) - roughly equivalent to the width of a hair split into 10,000 strands.
-
NewsWHO convenes Emergency Committee to tackle mpox surge in Congo and neighbours
WHO Director-General Tedros Adhanom Ghebreyesus announced the convening of an Emergency Committee under International Health Regulations to advise on whether the Africa outbreak represents a public health emergency of international concern.
