NewsBeewolves protect symbiont microbes from toxic gas release
The symbiosis of these digger wasps with their bacterial helpers involves protecting the symbionts from toxic nitric oxide released by beewolf eggs to kill pathogens, research shows.

NewsSoil microbes help plants cope with drought, but not how scientists thought
Researchers have found microbes help plants cope with drought, but not in response to plants’ cries for help - instead, the environment itself selects for drought-tolerant microbes.

NewsInterferon could help reduce the spread of COVID-19
Results of an innovative clinical trial have shown that the drug interferon could help reduce the spread of COVID-19 from a positive person to their household contacts, with the study helping to inform treatment options for a future pandemic.

NewsDesert microbes turn on drought tolerance when needed
Germinating Arabidopsis and alfalfa with a microbe taken from the roots of a common desert plant has been shown to help them to thrive under drought conditions.

NewsBiosurfactants may offer green solution for tackling oil spills
Researchers investigating whether biosurfactants could increase microbiological oil degradation in North Sea seawater say there is potential for a more effective and environmentally friendly oil spill response.

NewsRapid test for cystitis deploys phages to destroy pathogens
Scientists have developed a rapid test that employs the natural viral predators of bacteria, bacteriophages. The researchers also genetically modified the phages to make them more efficient at destroying the pathogenic bacteria.

NewsNew method builds fluorescent nanotubes to detect bacteria and viruses
Researchers have developed a new approach to construct modular optical sensors which are capable of detecting viruses and bacteria.

NewsPro1 protein malfunction allows rice blast fungus to thrive
Mutations in Pro1 - a mating-related protein - make rice blast fungus sterile, but may provide an adaptive advantage, a new study shows.
-
NewsProbiotic combo stops bacteria that cause toxic shock syndrome
A probiotic combination could reduce incidence of toxic shock syndrome, a rapid-onset, life-threatening disease associated with strains of Staphylococcus aureus.

NewsFly toolkit created for investigating COVID-19 infection mechanisms
A new ‘fly-to-bedside’ resource offers a shortcut for developing drug therapies needed for long COVID and future coronavirus outbreaks.

NewsWormlike animals are first amphibians shown to pass microbes to their offspring
Skin-feeding does more than provide nutrients for young caecilians - it also helps the mother pass microbes from her skin and gut down to her young, inoculating them to jump-start a healthy microbiome.

NewsNew Staph spa type emerges in Jordan as primary cause of dairy bovine mastitis
A new spa type of Staphylococcus aureus has emerged in Jordan which has been identified as the primary cause of dairy cow mastitis in the region.

NewsImmune systems develop ‘silver bullet’ defences against common bacteria
Immune systems develop specific genes to combat common bacteria such as those found in food, new research shows.

NewsBreakthrough harnesses mRNA technology to develop malaria vaccine
A new mRNA vaccine targeting immune cells in the liver could be the key to tackling malaria, a disease that causes over half a million deaths each year, yet has no effective long-lasting vaccine.

NewsMolecular biologists identify framework for understanding RNA editing in a disease-causing parasite
Researchers have determined the architecture of the molecular machines that harbour gRNA strands and allow those strands to engage mRNA in the single-celled, disease-causing parasite Trypanosoma brucei.
-
NewsResearchers use mass spectrometry to explore antimicrobial resistance
Researchers are using single-cell mass spectrometry to determine whether cells with persistent pathogens will also have less intracellular drug levels to potentially explain antimicrobial treatment failure.

NewsNew treatment paves way to tackle chicken infections resistant to antibiotics
An innovative treatment paves the way for reducing antimicrobial resistance in the treatment of a deadly infection in chickens, according to an international team of researchers led by the University of Surrey.

NewsResearchers uncover novel bacterial communication system to combat AMR
Using a sophisticated mass spectrometry technology developed at SMART and MIT, researchers have discovered that the enzyme RlmN is a stress sensor for reactive oxygen species (ROS) – highly reactive molecules which can cause damage to bacteria. Source: SMART AMR (L to R) SMART researchers Dr Cui Liang, ...

NewsBioengineered yeast devouring agricultural waste could close carbon circle
Researchers report making modified yeast that can feed on a wider range of materials, many of which can be derived from agricultural by-products that we don’t use known as waste biomass.

NewsClose contact within households may not influence COVID-19 transmission
A study measuring the impact of close contact on SARS-CoV-2 virus transmission within households suggests that being in proximity to someone with the virus may not influence the likelihood of becoming infected.
