NewsResearchers reveal lipid-based communication between body and gut microbes
A new study shows how a host protein can specifically recognize bacterial lipids, thus triggering beneficial immune responses. It also highlights a new way the body actively shapes the gut microbiome by communicating with microbes to maintain balance.

News New study reveals our skin’s own bacteria can help protect us from the bad effects of sunlight
Researchers have substantiated that certain skin bacteria can protect us from the sun’s ultraviolet (UV) radiation specifically by metabolizing cis-urocanic acid using an enzyme called urocanase. This enables the skin’s ability to fine-tune how it responds to UV radiation.

NewsScientists reveal key bacterial immune mechanism
Researchers have uncovered a pivotal mechanism by which bacteria defend themselves against viral infection. Cyclic dinucleotides (CDNs), synthesized during activation of the cyclic oligonucleotide-based anti-phage signaling system (CBASS) immune mechanism, trigger the filamentous assembly of phospholipase effectors, which execute the downstream immune response.

NewsTough microbes found in NASA cleanrooms hold clues to space survival and biotech
A new study involving AMI member Professor Alexandre Rosado has reported 26 novel bacterial species growing inside cleanrooms associated with NASA space missions. They carry genetic traits associated with resilience to extreme environments.
-
NewsScientists ID previously unknown enzymes that can produce potentially antimicrobial agents
Micro-organisms generate potential agents for combating bacteria and fungi. Researchers have identified and optimized enzymes that can specifically generate a certain functional group of these natural substances, expanding the toolkit of potential agents.

NewsActivating ‘jumping genes’ speeds up bacterial evolution from decades to weeks
Scientists have developed a system to control and accelerate the evolution of changes in the bacterial genome structure, targeting small ‘jumping genes’, or DNA sequences known as insertion sequences.

NewsHeart rhythm disorder traced to bacterium lurking in our gums
A new study finds that a gum disease bacterium can slip into the bloodstream and infiltrate the heart. There, it drives scar tissue buildup—known as fibrosis—distorting the heart’s architecture, interfering with electrical signals, and raising the risk of atrial fibrillation (AFib).

NewsBacterium yields secrets of how it produces ‘organic dishwashing liquid’ to degrade oil
The marine bacterium Alcanivorax borkumensis feeds on oil by producing an ’organic dishwashing liquid’ which it uses to attach itself to oil droplets. Researchers have now discovered the mechanism by which this “organic dishwashing liquid” is synthesized.

NewsTissue geometry drives bacterial infection: new mechanism uncovered
Researrchers have uncovered a novel mechanism by which tissue geometry regulates bacterial infection dynamics. The study employs a multidisciplinary approach to reveal how host tissue structure, mechanical forces, and cellular signaling shape infection patterns.

NewsResearchers reveal how fungi ‘manipulate’ the course of tumors
In pancreatic ductal adenocarcinoma (PDA), the abnormal colonization of fungal communities has become a research hotspot. New research indicates that Malassezia is not only a ’marker’ in the tumor microenvironment but also a potential driver of cancer development.
-
NewsSlow-growing bacteria respond more sensitively to their environment
A new study reveals that the responsiveness of bacterial cells to environmental stimuli is directly linked to their growth rate: the slower cells grow, the more sensitively they respond. This increased sensitivity can give the cells a crucial survival advantage.
-
NewsResearchers find new defense against hard-to-treat plant diseases
Scientists have developed a new approach to countering citrus greening and potato zebra chip diseases. Their method uses spinach antimicrobial peptides, known as defensins, which naturally defend plants.
-
NewsDiscovery opens up for new ways to treat chlamydia
Researchers have discovered a type of molecule that can kill chlamydia bacteria but spare bacteria that are important for health.

NewsBacteria: Recording gene activity more efficiently
Researchers have presented a step-by-step protocol for creating single bacterial transcriptomes with MATQ-seq. The protocol also includes the experimental and computer-aided analysis of the data.

NewsScientists discover antibiotic resistance in newly identified bacterium
Staphylococcus borealis has been found to be resistant to several different types of antibiotics, posing a potentially significant problem for the elderly.
-
NewsSpiritual healing sites could be linked to antibiotic-producing microorganisms
A study by AMI member Dr Gerry Quinn highlights the potential of spiritual healing sites as fertile ground for novel antibiotics, particularly from Streptomyces bacteria, known for producing the majority of current antibiotics.
-
NewsShaken and stirred: why Klebsiella pneumoniae strain 007 poses a deadly threat
A new study has uncovered the secrets of a particular strain of the bacterium Klebsiella pneumoniae, revealing a potentially deadly genetic capacity for both antimicrobial resistance and virulence.
-
NewsBreakthrough discovery uses gut bacteria and AI to diagnose a chronic pain syndrome
Scientists have developed AI technology that can detect patterns in gut bacteria to identify complex regional pain syndrome (CRPS) with remarkable accuracy, potentially transforming how CRPS is diagnosed and treated.
-
NewsFood as medicine: How diet shapes gut microbiome health
New research shows how mice fed a Western-style diet are not able to rebuild a ‘healthy’, diverse gut microbiome following antibiotic treatment. These mice were also more susceptible to infection by pathogens like Salmonella.
