NewsScientists probe how proteins are inserted into cell membranes
Researchers looking at the cell membrane investigate how the proteins manufactured by the ribosomes in the cell interior reach their position within the membrane in the correct form and when the processes became established over the course of evolution.

NewsRice-crayfish farming strengthens soil nutrient cycling
Using metagenomic sequencing, a study has shown that integrated rice-crayfish systems increase the abundance of functional genes involved in methane oxidation, nitrogen degradation, denitrification, organic phosphorus mineralization, and phosphorus transport compared with rice monoculture. Source: Brian Tomlinson from Milton Keynes, UK Crayfish. The paddy planting area within ...

NewsAntibiotics reverse damage caused to blood stem cells by chronic Salmonella
A new study has revealed that long-term Salmonella infections severely damage blood stem cells - but this damage is completely reversible. Giving an effective course of antibiotics fully restores the stem cells, allowing them to recover their health and rebuilding power.

NewsSoil moisture tips the balance of nitrogen cycling
A new study reveals that nitrite accumulation is not simply a chemical outcome, but the result of mismatched microbial activities between ammonia oxidizers and nitrite oxidizers.

NewsCorals show climate change is reshaping the rules of survival
Which species benefit from climate change, and which are coming under pressure? Using corals as an example, researchers demonstrated that even seemingly successful life strategies can lose their advantage when environmental conditions change.

NewsScientists uncover the hidden air risks in university cafeterias
By assessing two university cafeterias, a new study has shown that both sites had elevated temperature and PM10 levels, while one also showed high carbon dioxide and the other high total bacterial counts.

NewsScientists deploy biofilm-targeting approach to improve crop disease resistance
A new study reports a biofilm-targeting approach for improving crop disease resistance. By replacing the native chloroplast transit peptide (CTP) of MOC1 with a secretory signal peptide (SP), the team redirected the enzyme from chloroplasts to the apoplast.

NewsDiabetes worsens long COVID complications
In a study involving 870 participants, people with diabetes took longer to recover from the virus and experienced more severe cardiac complications, as well as greater physical and cognitive difficulties.

NewsCryo-EM helps identify the mechanisms of dental plaque formation
Researchers used cryo-electron microscopy to provide new insights into how Porphyromonas gingivalis causes plaque formation, revealing the 3D structure of Mfa pili, an arm-like filament which enables the bacteria to stick to host tissues and other microbes.

NewsResearchers affirm long-held belief that viruses can trigger Parkinson’s disease
Researchers have developed a model that uses a nontoxic way to generate the symptoms of Parkinson’s: infection with a virus. It proves that a simple viral infection can trigger the exact brain damage and physical disabilities in animal models that are seen in people with Parkinson’s disease.

NewsSame day administration of COVID-19 and influenza vaccines not associated with increase in adverse events
A target trial emulation found that same day coadministration of the COVID-19 and influenza vaccines was not associated with a higher risk of serious or clinically meaningful adverse events compared with receiving only an influenza vaccine.

NewsCase study: Fatal rabies in a child
Ontario’s first case of fatal rabies since 1967 provides critical guidance to help prevent death from rabies in future instances. The parents agreed to share their son’s case to help raise awareness of rabies.

NewsA 'copper economy' helps fungi and bacteria build better biofilms
Scientists have discovered that two common human pathogens can work together by managing copper in their shared environment - a finding that could open new ways to break down stubborn mixed biofilms.

NewsDecline in plankton across North East Atlantic sends stark warning for ocean health
A new study has used more than six decades of data to show that plankton abundance is declining across vast swathes of the North East Atlantic – a region covering the Atlantic Ocean from Portugal to Norway, and the entirety of the North Sea.

NewsHantavirus in the South Atlantic: A one health and microbiome wake‑up call
The hantavirus pulmonary syndrome outbreak on MV Hondius shows how global travel and environmental change are reshaping how zoonotic viruses emerge. In a new commentary, Professor Lu proposes four initiatives aligned with Microbiome and One Health.

NewsStudy: China reverses widespread freshwater deoxygenation via wastewater management
Freshwater ecosystems worldwide have been suffering from declining oxygen levels that threatens biodiversity, fisheries, and ecosystem stability. However, a new study offers hope: targeted nutrient management via wastewater control can reverse this trajectory, even in the face of rapid climate warming.

NewsSea anemone flips a human antiviral strategy on its head
A new study has uncovered a previously unknown antiviral defense mechanism in sea anemones, revealing that animals may have evolved more than one way to fight viral infections.

NewsNew research makes critical discovery for the global fight against antibiotic resistance
A study has found that an unusual pairing of two commonly used antibiotics can kill and stop the spread of resistance in a highly drug-resistant bacterium, Pseudomonas aeruginosa.
