NewsPackaging tray can signal Salmonella contamination before food is unwrapped
Researchers have created a new packaging tray that can signal when Salmonella or other dangerous pathogens are present in packages of raw or cooked food such as chicken.
-
NewsElectrons and microbes are key to bio-based nylon process
Researchers have developed a process that can produce adipic acid, one of two building blocks of nylon, from phenol through electrochemical synthesis and the use of microorganisms.
-
NewsArtificial cells show that ‘life finds a way’
Scientists studying a synthetically constructed minimal cell that has been stripped of all but its essential genes have found it can evolve just as fast as a normal cell.
-
NewsGene expression in apicoplast could be target for malaria treatment
Gene expression within the apicoplast, an organelle in the malaria parasite Plasmodium falciparum is regulated by melatonin in host blood, and intrinsic parasite cues, via a factor called ApSigma, a recent study reveals.
-
NewsVaginal suppository with lactobacilli can prevent recurrent cystitis
Scientists find that administration of Lactobacilli could mitigate the differences in vaginal microbiota between women with and without recurrent cystitis.
-
NewsPurecap technique opens doors to more effective mRNA vaccines
Researchers have developed a method to produce highly active mRNA vaccines at high purity using a unique cap to easily separate the desired capped mRNA.
-
NewsFrequent use of antibiotics linked to severe Covid outcomes
Frequent and diverse use of antibiotics may be associated with developing more severe outcomes after a COVID-19 infection, including death, a new study has shown.
-
NewsSelf-produced bacterial toxin induces cancer cells to ‘commit suicide’
Researchers have encoded a toxin produced by bacteria into mRNA (messenger RNA) molecules and delivered these particles directly to cancer cells, causing the cells to produce the toxin – which eventually killed them with a success rate of 50%.
-
NewsScientists develop all-species Covid test
In an advance that will help scientists track coronavirus variants in wild and domesticated animals, researchers report they can now detect exposure to the SARS-CoV-2 virus in any animal species.
-
NewsNew bacterial blueprint will help fight antibiotic resistance
Scientists have gained high-res structural insights into a key bacterial enzyme, which may help chemists design new drugs to inhibit it and thus suppress disease-causing bacteria.
-
NewsCOVID-19 jab reduced disease disparities between low- and high-income communities
COVID-19 vaccination helped reduce disparities in disease incidence between low- and high-income communities, according to a new analysis led by Cedars-Sinai investigators.
-
NewsScientists uncover secrets of bacteria threatening Vidalia onion production
Researchers have confirmed which genes in the bacterial pathogen Pantoea ananatis high virulence cluster are essential and which genes contribute partially to a disease that causes rotting symptoms in Vidalia onions.
-
NewsAlarming antibiotic resistance discovered in war-torn Ukraine
Microbiologists investigating bacterial resistance among the war-wounded Ukrainian patients treated in hospitals have warned that the entire European region is under threat after finding that many were affected by bacteria that exhibited an extremely high level of antibiotic resistance.
-
NewsNatural molecule added to toothpaste may help prevent plaque and cavities
Scientists have discovered that 3,3′-Diindolylmethane (DIM), a naturally occurring molecule also known as bisindole, reduces the biofilms that produce plaque and cavities by 90% and is also found to have anti-carcinogenic properties.
-
NewsNew CRISPR gene editing approach opens up more of the genome
Scietnists have come up with a new way to identify diverse CRISPR RNA variants that can specifically home in on challenging areas of DNA to target for editing. The new approach opens up more of the genome for editing, enabling the repair of mutations associated with more diseases.
-
NewsNew enzyme designed using Antarctic bacteria and computer calculations
For the first time, researchers have succeeded in predicting how to change the optimum temperature of an enzyme using large computer calculations and based on a cold-adapted enzyme from an Antarctic bacterium.
-
NewsImmune-boosting therapy helps honey bees resist deadly viruses
Scientists have successfully tested a novel way of boosting honey bees’ immune systems to help them fend off deadly viruses, which have contributed to the major losses of the critical pollinator globally.
-
NewsFuture medicines could feature ingredients targeting bacterial motility and chemotaxis
Future medicines will probably be made up of a cocktail of compounds that inhibit different bacterial targets, including some that act against their motility and chemotaxis mechanisms, a new review suggests.
-
OpinionMicrobial hydrogen cycling - the good, the bad and the ugly
With global populations looking likely to top 10 billion by the year 2050, the practices that we use to grow food need to adapt in kind - and what better way is there but to harness the innate power of microbes!

News‘Hospital pathogen’ widespread in Vietnam’s environment
A pathogen considered to be a cause of hospital infection is widespread in Vietnam, turning up in farm soil and pig faeces as well as hospital beds and toilet floor surfaces, with 70% of isolates found to be resistant to at least one class of antimicrobials.
