NewsBacterial duo feed cuticle in wood-eating beetles
Two bacterial symbionts supply auger beetles with the vital nutrients for the synthesis of a sturdy exoskeleton.

NewsNew method may harness radiation-resistant bacterium
Researchers find a novel way to expand applications of the hardy bacterium Deinococcus radiodurans, using gene deletion techniques.

NewsAntimicrobial use in agriculture can breed bacteria resistant to first-line human defences
A new study has shown that overuse of antimicrobials in livestock production can drive the evolution of bacteria more resistant to the first line of the human immune response.

NewsStool transplants more effective than antibiotics for treating recurring, life-threatening gut infections
A new Cochrane Review has found that, compared with standard antibiotic treatment, stool transplantation can increase the number of people recovering from Clostridioides difficile infection from 40% to 77%.

NewsNew biologic effective against major infection in early tests
Researchers have shown in early tests that a bioengineered drug candidate can counter infection with Staphylococcus aureus – a bacterial species widely resistant to antibiotics and a major cause of death in hospitalized patients.

NewsMicrobes will transform our town and cityscapes - and here’s how
A new review examining microbes and architecture reveals how buildings of the future will be unrecognisable by modern standards as they perform functions such as bioremediation that do not exist today.

NewsStudy of Covid contamination of shipping materials may yield guidance for goods transportation
Researchers investigating how environmental factors affect the persistence of two different, highly transmissible Omicron variants on shipping materials find that viability depends on the type of surface, the temperature and the original viral concentration.

NewsPhylogenetic analysis reveals the lessons of previous bird flu outbreaks
Researchers have confirmed that the H7N9 virus was likely circulating in poultry for several months before being discovered in both poultry markets and humans and that more poultry markets may have been affected than previously believed.

NewsFirst human respiratory organoid culture system reveals secret of Omicron’s transmissibility
Researchers have established the first human respiratory organoid culture system and unveiled a novel mechanism for the high transmissibility of SARS-CoV-2 Omicron variant.

NewsBacteria’s antibiotic-evading super polymers do best in harsh conditions of the gut
New research has shown that gut bacteria’s extracellular appendages known as F-pili are stronger in the turbulent conditions of the gut, helping the bacteria transfer resistance genes to each other more efficiently and to clump into ‘biofilms’ – protective bacterial consortia – that help them fend off antibiotics.

NewsPlankton trawl reveals new viruses related to both giant viruses and herpes viruses
Metagenomic data from Tara Oceans on marine plankton has enabled the discovery of a major group of DNA viruses found abundantly from the equator to the poles: mirusviruses.

NewsEconomic growth alone is not enough to eliminate rabies, research finds
Economic growth alone may not be enough to deliver the internationally agreed target to end human deaths from dog mediated rabies, according to new research.

NewsObese pregnant women infected by zika virus have impaired immune response
Researchers have shown for the first time that gestational obesity associated with infection by zika virus influences the placenta’s antiviral response, weakening the organ’s capacity to attack the pathogen and protect the foetus.

NewsInfectious SARS-CoV-2 isolated from hospital air samples
Scientists have succeeded in isolating infectious particles of the SARS-CoV-2 virus from air samples collected from hospital rooms of COVID-19 patients and kept frozen for more than a year, a new study shows.

NewsGut bacteria could be behind weaker immune responses to COVID-19 vaccine
Digestion of fucose sugar by bacteria in our digestive tract could be hampering how effectively we respond to the COVID-19 mRNA vaccine.

News‘Antibiotic culture’ permeates US hospital ICUs, study finds
A new study reveals that there continues to be an ’antibiotic culture’ in US hospitals, meaning that the preference for antibiotics is related to their perceived role as ’magic bullets’.

News New cell-killing toxin discovered in an environmental pathogen
An international research team has discovered how a bacterial toxin, known as Ssp, is capable of entering and killing a wide range of living cells, including human cells.

NewsEuropean-funded €2.3m project will revolutionize bioprinting of living materials
The PRISM-LT project has received a €2.3 million grant for a five-year program that aims to create an adaptable platform for 3D bioprinting of living tissue with dynamic functionalities and predictable shapes.
