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.
-
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, ...

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.
-
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.
-
NewsNew cholera substrains in Bangladesh uncovered by genomic surveillance
Researchers have uncovered two new cholera substrains in a displaced refugee population in southern Bangladesh, where a pre-emptive mass vaccination campaign of over one million refugees was successful in preventing an epidemic.
-
NewsResearchers discover novel biomarker for sepsis severity
Scientists have identified a novel biomarker that could change the way sepsis is approached and treated.
-
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.
-
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.
-
NewsScent dogs can detect COVID-19 more rapidly and accurately than current tests
Scent dogs may represent a cheaper, faster and more effective way to detect COVID-19, and could be a key tool in future pandemics, a new review of recent research suggests.
-
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.
-
NewsBacteria discreetly living in throat are primary source of Strep A transmission
Breakthrough research has found that Group A Streptococcus (GAS) infections are more likely transmitted from asymptomatic throat carriage than skin-to-skin contact in communities with high rates of infection.
-
NewsBacterial protein may contribute to reduced fertility and birth defects
Scientists have published new findings that emphasize the crucial role of the urinary and genital tract microbiota in adverse pregnancy outcomes and genomic instability that originate in the womb during foetal development.
