NewsCooler conditions spur bacterial prey species to become the predator
In a new study, two species of bacteria grown in a lab reversed their predator-prey relationship after one species was grown at a lower temperature.

NewsSpace-grown salad more susceptible to foodborne infections than on earth
A research team finds lettuce and other plants are more susceptible to bacterial infections in space than on Earth.

NewsResearchers reveal how archaea toggle the nitrogen-uptake switch
By tightly regulating nitrogen uptake, microorganisms avoid overeating nitrogen and thus wasting energy. Scientists now reveal how some methanogenic archaea manage to do so.

NewsStrong links found between long COVID and ME/CFS
People suffering from long COVID or Myalgic Encephalomyelitis /Chronic Fatigue Syndrome (ME/CFS) could benefit from a coordinated treatment strategy, a new study has found.
-
NewsScientists make COVID receptor protein in mouse cells
Initially motivated to make receptor-based sensors and therapies for COVID-19, scientists develop general strategy for producing other complex proteins.

NewsShallow soda lakes show promise as cradles of life on Earth
A new study reports that a shallow “soda lake” in western Canada shows promise for matching the requirements for the emergence of life.

NewsPhages help to identify people at risk of developing TB
A novel approach to studying the progression of tuberculosis (TB) from infection to disease has identified and treated people at increased risk of developing the disease that current methods of testing would not.

NewsScientists uncover how gadolinium and sulfamethoxazole impact antibiotic and heavy metal resistance genes in activated sludge systems
Researchers investigated the co-occurrence of Gd and SMX in wastewater pollution by applying metagenomics to analyze the mechanisms of changes in ARGs, MRGs, MGEs, and genera in an activated sludge system.

NewsFungus yields different pathway to the same pharmaceutically important substance
Researchers analyze a fungal biosynthetic pathway and discover a capable enzyme.

NewsViruses can cause multiple myeloma cancer, case study finds, offering hope for treatment
An unusual clinical case has led to the discovery that hepatitis B and C viruses are one of the causes of multiple myeloma, and that eliminating infection with antivirals is often the way to fight this type of cancer.

NewsStudy reveals impact of skin microorganisms on earthworm toxicity in polluted environments
Changes in the community of skin-based microbes correlate more significantly with earthworm toxicity than those in intestinal microorganisms, especially under combined soil contaminations.

NewsFIFA World Cup ends with win for Argentina - and COVID-19
The 2022 FIFA World Cup ended with a win for Argentina over France, but it was also a triumph for SARS-CoV-2 with a significant jump in the number of cases, some of which could have been prevented, a new study suggests.

NewsSemen microbiome health may impact male fertility
The semen microbiota might play a crucial role in influencing sperm parameters and enhancing male fertility, a new study suggests.
-
NewsAntibiotics highjack bacterial immunity
Molecular defense system protects bacteria from viruses and at the same time makes them susceptible to antibiotics.
-
NewsPhages found that bring slumbering bacteria out of deep sleep and then kill them
Researchers questioning whether evolution might have produced bacteriophages that specialise in dormant bacteria and could be used to target them have now shown that such phages, though rare, do indeed exist.
-
NewsScientists translate nuclear waste site data into microbial ecosystem insights
A flagship seven-year study explores how environmental stresses influence different ecological processes shaping the composition and structure of microbial communities in groundwater.
-
NewsMolecular switch plays central role in bacterial dysentery
The regulation of virulence genes in Shigella bacteria is mediated by a CTP-dependent transcription factor.
-
NewsSingle-celled kamikazes spearhead bacterial infection
Study reveals how a few soldier cells confer virulence to an entire bacterial population by sacrificing themselves.
-
NewsProject to monitor and predict marine biological hazards
Project to provide technology- and data-based recommendations for early-warning systems and information chains to minimise the effects of marine biological hazards.

NewsSpatial statistics experts warn that statistical proof of COVID-19 market theory is flawed
Huanan Seafood Wholesale Market in the Chinese city of Wuhan is not the only possible place of origin of the COVID-19 pandemic, a new study warns.
