NewsCinnamic acid blocks plasmid conjugation to slow antibiotic resistance spread
A new study reveals that cinnamic acid, a widely used food additive found in cinnamon, can effectively inhibit plasmid‑mediated conjugation, a major route for the global spread of antibiotic resistance genes (ARGs).

NewsTiny switch controls rare rotary machine in bacteria - and can even reverse direction of spin
Researchers have discovered a tiny molecular switch that can control and reverse the direction of a rare rotary machine linked to motility, surface colonization and protein secretion in bacteria.

NewsYellow food coloring changes gut microbiome in early life
Researchers found that the gut microbiotaof young rats changed with exposure to acceptable daily intake levels of the food coloring tartrazine. The males showed increases in bacteria linked to low-grade inflammation and they also did not gain as much weight as was expected.

NewsCosmetics from waste? New microbial discovery could enable more sustainable production of high-value chemical products
Researchers have made a key discovery about how certain bacterial strains produce a set of economically valuable chemicals — opening the door to new, more sustainable production methods. A family of molecules could be made via bacterial fermentation instead of from palm oil, as they are today.

NewsNew insights into how bacteria manage DNA
New analytical methods have enabled researchers to uncover how the sequence, physical shape and flexibility of bacterial DNA guide the activity of an enzyme called DNA gyrase, which previously got all the credit for managing DNA.

NewsHigh levels of gut bacterial toxin trigger lupus nephritis
Research suggests that using antibiotics to target the Ruminococcus gnavus lipoglycan, or the protein it activates on immune cell surfaces to amplify damaging inflammation, could serve as an alternative to current lupus nephritis therapies that suppress the immune system.

NewsResearchers fight oral cancer with bioengineered chewing gum
Research shows that antiviral and antibacterial chewing gums reduce the levels of three microbes linked to worse outcomes in oral cancers, paving the way for more effective and affordable therapies.

NewsResearch on tick-transmitted disease reveals potential weakness, opening paths to new treatments
Tularemia is a rare but highly infectious disease caused by Francisella tularensis, a bacterium that can evade immune defenses. Scientists have isolated and studied a set of proteins that play a central role in infection, revealing a potential weakness.

NewsNew research reveals mechanisms behind coffee’s positive effects on the gut-brain axis
First of its kind research shows the potential role of coffee as a further intervention to promote positive gut health and its effects on the gut-brain axis. Coffee was found to positively affect perceived mood and stress levels in individuals taking part in this study.

NewsE. coli and ‘good’ bacteria balanced by breastmilk in baby gut microbiomes
Sugars contained exclusively in breast milk are helping to feed an important balance of bacteria in babies’ developing gut microbiomes, according to a study that describes how babies who are breastfed maintain a mutually beneficial co-existence of E. coli and Bifidobacterium.

NewsResearchers disable antimicrobial resistance in cystic fibrosis-associated bacteria
A newly discovered mechanism renders antibiotic-resistant bacteria vulnerable by disabling both their individual resistance and a process known as cross-protection, the ability of resistant bacteria to shield nearby, otherwise sensitive strains.
-
NewsMetagenomic software advance boosts research into microbial diversity
Researchers studying the diversity of microbes in environmental samples now have access to a new tool that opens the door to cheaper, more accessible analysis of their samples.

NewsNew lactic acid bacteria for plant-based yogurt alternatives
Researchers find that a particular type of lactic acid bacteria has considerable potential for producing plant-based yoghurt alternatives. The bacteria inhibit potentially harmful bacteria and break down sugars that can cause stomach discomfort.

NewsCDI breakthroughs lead to new drug development deal for deadly NTM bacteria
Scientists have developed new compounds against non-tuberculous mycobacteria which are now the subject of a new collaboration and license agreement with the Switzerland-based and publicly listed BioVersys AG.

NewsHas life-saving HIV therapy contributed to increased rates of a sexually transmitted disease?
A study has uncovered an unintended consequence of a major medical breakthrough: while the availability of HIV treatments in the late 1990s dramatically improved survival, they also contributed to a resurgence in syphilis, a sexually transmitted infection.

NewsScientists probe how neurons sense bacteria in the gut
Neural interaction with bacteria, e.g. in the gut microbiome, has important effects on brains of animals from worms to people. A new study investigates how neurons sense bacteria by revealing, in nematodes, the bacterial signals that a key neuron detects.

NewsNew biosensor for detecting active tuberculosis
A research team is developing a sensor that paves the way for the rapid, selective and cost-effective detection of active tuberculosis. The device detects the presence of a protein secreted by Mycobacterium tuberculosis, the bacterium that causes the disease.

NewsGut bacteria predict skin cancer recurrence, but only when matched for ‘microbial fingerprint’
The specific mix of bacteria living in a person’s gut can predict the chances that melanoma will recur after surgery and immunotherapy, which helps immune cells target cancer cells, according to a new study.
-
NewsEngineered dual-bacterial sensors turn chemical signals into electricity
Most bacterial information transmission is done via electricity. While electricity-emitting bacteria exist, manipulating them into useful sensors has been quite challenging. Researchers recently developed a flexible bioelectrical sensor system called electroactive co-culture sensing system.

NewsHow tiny cave shrimps grazing on microbes power the underworld of the Yucatan
Because they convert microbial growth in sinkholes beneath the Yucatan Peninsula into animal biomass, Typhlatya shrimps act as “keystone species”, introducing essential nutrients into the cave’s food web. They serve as a crucial initial link that larger subterranean predators feed on.
