NewsShort-lived volcanic island harboured sulphur-metabolizing microbes
Researchers discovered a unique microbial community that metabolizes sulphur and atmospheric gases, similar to organisms found in deep sea vents or hot springs, on a volcanic island that only lasted for seven years.

NewsLong-term projects reveal how warming planet will impact microbe carbon cycling
A team of researchers led by the University of Massachusetts Amherst has helped to untangle one of the knottiest questions involving soil microbes and climate change: what effect does a warming planet have on the microbes’ carbon cycling?

NewsResearchers pinpoint enzyme that limits electrosynthesis by Shewanella
Researchers at Michigan State University have identified an enzyme that is a limiting factor to microbial electrosynthesis by Shewanella oneidensis, a bacterium that could potentially capture carbon dioxide emissions to produce useful materials.

NewsIceland could feed Europe with cyanobacteria reactors powered by renewables
Iceland could play a pivotal role in European food security, providing over 40 million Europeans with a safe, sustainable, and locally-produced protein source over the next decade, while mitigating over 700 million tons of CO2 emissions, a new study suggests.

NewsCorals may punish cheating symbiont algae by cutting off their food supply
Corals may ‘punish’ the algae that live inside them by cutting off their food supply if such algae become selfish and renege on their part of the resource-sharing deal with the coral as part of their symbiosis.

NewsSalmonella exposure poses a risk for colon cancer
Researchers who studied human colon cancer tissue samples and animal models have found that exposure to salmonella was linked with colon cancers that developed earlier and grew larger.

NewsProbiotic markedly reduces staph colonisation in phase 2 trial
A approach to control Staphylococcus aureus bacterial colonization in people—using a probiotic instead of antibiotics—was found to be safe and highly effective in a Phase 2 clinical trial.

NewsSilent flagellin delivers insights into how gut bacteria evade the immune system
Researchers from the Max Planck Institute for Biology Tübingen have identified a new type of flagellin in the human gut, termed ‘silent flagellin’, that binds to the immune receptor Toll-like receptor 5 without inducing a pro-inflammatory response. Their work addresses the long-standing question of how benign gut microbes evade the ...

NewsFungi convert ocean plastic into ingredients for drug industry
Research on fungi underway at the University of Kansas has helped transform tough-to-recycle plastic waste from the Pacific Ocean into key components for making pharmaceuticals.

NewsOvarian cancer linked to bacteria colonization in microbiome
A specific colonization of microbes in the reproductive tract is commonly found in women with ovarian cancer, according to a new study from Mayo Clinic’s Center for Individualized Medicine.

NewsScientists discover potential new method to treat superbug infections
Researchers at the University of Galway outline how the building blocks of DNA can boost penicillin-type antibiotics in the fight against MRSA.

NewsResearchers evaluate mass spectrometry approaches for mould identification
A study by researchers at Chung-Ang University is the first to compare the sensitivity and accuracy of three MALDI-TOF MS instruments as well as the efficacy of three pretreatment methods for filamentous fungal identification.

NewsMadagascar mouse lemur retroviruses surprisingly similar to ones found in polar bears or sheep
Researchers studying the mouse lemur genome have identified two endogenous retroviruses (ERVs) that are closely related to viruses found in other, very different mammals such as polar bears or domestic sheep.

NewsResearch finds key connection between Legionnaires disease and ‘host’ amoeba
A new study of domestic and hospital drinking water systems found Legionella in 41% of samples – with Flinders University researchers making a key connection between the pathogen’s co-existence with a ‘host’ microorganism in all samples tested.

NewsGenetically engineered bacterium can synthesize melanin nanoparticles
Researchers have heterologously expressed a tyrosinase gene in Escherichia coli to synthesize melanin nanoparticles which offer potential for tumour treatment.

NewsChange in genetics of SARS-CoV-2 evolved to counter weakness caused by the virus’s initial mutation
Researchers at Johns Hopkins Medicine say their new studies suggest that the first pandemic-accelerating mutation in the SARS-CoV-2 virus, which causes COVID-19, evolved as a way to correct vulnerabilities caused by the mutation that started the SARS-CoV-2 pandemic.

NewsTwo new bacterial species identified from patients with inflammatory bowel disease
Investigators at University Medical Center Utrecht and Yale University have isolated and characterized two new bacterial species from patients with inflammatory bowel disease (IBD).

NewsGut bacteria can impact immune cells that damage brain tissue
Gut bacteria affect the behaviour of immune cells throughout the body, including ones in the brain that can damage brain tissue and exacerbate neurodegeneration in conditions such as Alzheimer’s disease, according to new research.

NewsScientists synthesize precursors of powerful anti-cancer drug in yeast cells
Researchers have identified a novel method for the biological synthesis of catharanthine and vindoline - the two pharmacologic precursors of anti-cancer drug vinblastine - using yeast cells.

NewsResearchers modify hydrogen-producing enzyme to protect it from oxygen destruction
Researchers have genetically modified a hydrogen-producing enzyme so that it is protected from oxygen, countering a key barrier to producing molecular hydrogen with enzymes from bacteria and algae.
