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.
-
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.

OpinionMadonna, Mass Consumption and Microbes
Back in 1984, Madonna already knew we were ‘living in a material world’, and since then, things have only got worse.
-
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.
-
NewsMulticellular life on Earth ‘didn’t arise as described in textbooks’
Oxygen didn’t catalyze the swift blossoming of Earth’s first multicellular organisms, a new study says, defying a 70-year-old assumption about what caused an explosion of oceanic fauna hundreds of millions of years ago.
-
NewsPicolinic acid reveals its broad-spectrum antiviral abilities
Picolinic acid, a natural compound produced by mammalian cells, can block several disease-causing viruses such as SARS-CoV-2 and influenza A viruses, according to a new study.
-
NewsMicrobiologist and virologist creating Global Pandemic Research Alliance
Columbia University virologist Professor David Ho and The University of Hong Kong (HKU) microbiologist Professor Kwok-yung Yuen are teaming up to create a global alliance for conducting research in emerging infectious diseases.
-
NewsScientists track global atmospheric spread of harmful microbes
Researchers have published an article that helps to understand the intercontinental spread of harmful microorganisms through the atmosphere.
-
NewsGlobal overview of antibiotic resistance determinants yields surprising findings
Scientists have developed a statistical model of the main determinants behind worldwide antibiotic resistance dynamics based on a large-scale spatial-temporal analysis.
-
NewsStudy suggests the carbon cycle is speeding up
In Northern ecosystems, rising temperatures are depleting the soil carbon reservoir, a new study reveals.
-
NewsScorpionfish protein kills drug-resistant bacteria from patients with cystic fibrosis
A scorpionfish protein effectively kills antibiotic-resistant bacteria from patients with cystic fibrosis, escaping an immune response that renders the human version of the protein ineffective.
-
NewsDual wavelengths of light effective against antibiotic-resistant bacterium
Scientists have combined two light wavelengths to deactivate a bacterium that is invulnerable to some of the world’s most widely used antibiotics, giving hope that the regime could be adapted as a potential disinfectant treatment.
-
NewsResearchers uncover mechanisms underlying Helicobacter pylori-induced gastric cancer
A new study shows how oncoprotein CagA from Helicobacter pylori disrupts Wnt/PCP signalling and promotes gastric carcinogenesis.
-
NewsApplied Microbiology International announces new president
Professor Jack Gilbert has taken over the reins from Professor Brendan Gilmore as President of Applied Microbiology International (AMI).
-
NewsOmicron subvariant BA.5 efficiently infects lung cells
Over the course of evolution of Omicron subvariants, viruses may arise that regain the ability to effectively spread in the lung and cause severe illness in risk patients and people with insufficient immunity, a new study suggests.

NewsBioluminescent bacteria coordinate signalling to colonize squid’s light organ
Researchers reveal how bioluminescent bacteria coordinate their behaviour to colonize the Hawaiian bobtail squid through cellular signaling and cues from the environment.
