NewsSame moves, different terrain: How bacteria navigate complex environments without changing their playbook
New research shows that a diverse group of bacteria has learned how to use the same basic movements to move through a wide range of environments no matter how complex, from unconstrained fluids to densely packed soil and tissues.

NewsMaternal microbiome compound may hold key to preventing liver disease
Children born to mothers who consume a high-fat, high-sugar diet during pregnancy and breastfeeding face a higher risk of developing fatty liver disease later in life. New research suggests that risk may be reduced by supplementing with a naturally occurring compound produced by healthy gut bacteria.

NewsA new study reveals how cholera virulence is activated
A new study provides a long-sought structural explanation of the regulatory cascade that allows Vibrio cholerae to colonize the human gut and produce the cholera toxin that causes life-threatening diarrhea.

NewsTB and HIV treatments are not enough for a full recovery
Existing treatments control TB and HIV, but the immune system does not revert to normal, helping explain why people living with HIV remain susceptible to infections and underscoring the need for immunotherapies.

NewsAboard the International Space Station, viruses and bacteria show atypical interplay
In a new study, terrestrial bacteria-infecting viruses were still able to infect their E. coli hosts in near-weightless “microgravity” conditions aboard the International Space Station, but the dynamics of virus-bacteria interactions differed from those observed on Earth.

NewsWhy don’t antibiotic-making bacteria self-destruct?
Scientists discovered a promising new antibiotic in a soil sample. The molecule, lariocidin, is produced by the microbe Paenibacillus and shows broad activity against pathogenic bacteria. Now, the researchers report how Paenibacillus avoids harm by its own antibiotic.

NewsResearch reveals hidden diversity of E. coli driving diabetic foot infections
New research has shed light on the diversity and characteristics of E. coli strains that drive diabetic foot infections, providing the first comprehensive genomic characterisation of E. coli strains isolated directly from diabetic foot ulcers across multiple continents.

NewsBirding enthusiasts can help songbirds avoid salmonella epidemics
Biologists are developing a tool to predict when deadly salmonella outbreaks are likely to happen in wild songbird populations so that people can protect their feathered friends by taking down bird feeders at the right time.

NewsNot only toxic but also a nutrient: guanidine as a nitrogen source
Cyanobacteria are key ecological players of global carbon and nitrogen cycles. They are also becoming increasingly important for carbon-neutral biotechnology. They could serve as green cell factories for a light-driven and sustainable production of chemicals and fuels – a central pillar of the sustainable bioeconomy. Source: André Künzelmann/UFZ ...

NewsProbiotic living microneedles designed by interbacterial competition for accelerated infected wound healing
Probiotic therapy offers a promising strategy for chronic infected wound management. Inspired by bacterial competitive interactions, researchers developed a multifunctional microneedle (MN) platform to overcome the limitations of weak competitiveness and poor penetration across biofilm barriers.

NewsRare microbial wrinkle structures - signs of ancient life - turn up in an unexpected place
Deep water sediment layers in the Dadès Valley in the Central High Atlas Mountains of Morocco have revealed rare microbial wrinkle structures formed far from sunlight.

NewsA protein found in the GI tract can neutralize many bacteria
The mucosal surfaces that line the body are embedded with defensive molecules that help keep microbes from causing inflammation and infections. One of these molecules, intelectin-2, has broad-spectrum antimicrobial activity against bacteria found in the GI tract.

NewsA gentler way to model deadly lung infections in old age
Researchers report a refined mouse model that successfully mimics chronic Pseudomonas aeruginosa lung infection in old age. The study introduces an agar bead-based delivery strategy that allows bacteria to persist in the lungs of aged mice without causing rapid death.

NewsSunlight-activated nanospray enables painless, antibiotic-free therapy for infected diabetic wounds
A research team has reported a multifunctional photodynamic nanospray for chronic infected wounds that harnesses natural sunlight to address persistent bacterial infections, impaired healing and severe pain simultaneously.

NewsGut bacteria protect mice with influenza A from bacterial pneumonia, study finds
Select gut bacteria protect mice against post-influenza virus secondary bacterial pneumonia, according to a study which sought to define whether intestinal bacteria influenced some individuals’ vulnerability to secondary bacterial infections following primary respiratory viral infection.

NewsGamma rays quickly toughen nitrogen‑fixing bacteria
Heat‑resilient biofertilizers could help crops cope with rising temperatures but engineering them has been slow and uncertain. A new study shows that pairing experimental evolution with controlled gamma‑ray mutagenesis can accelerate the path to heat‑tolerant nitrogen‑fixing bacteria.
-
NewsResearcher reveals secrets of bacteria that can swim upstream
Rather than washing pathogens away, strong fluid currents act as “guide rails” that align bacteria and accelerate their upstream migration. They discovered that this creates a “two-way invasion” where pioneer cells reach the source within minutes, seeding colonies that spread threefold faster than in still water.

NewsTeam shows how viral lysis of blue-green algae enhances ecosystem-scale productivity
Newly published interdisciplinary research shows viral infection of blue-green algae in the ocean stimulates productivity in the ecosystem and contributes to a rich band of oxygen in the water.

NewsResearchers deploy bacteria to make healthier sugar substitute
Researchers have developed a way to biosynthetically produce an otherwise rare sugar called tagatose, which could very well provide the sweetness and natural taste of table sugar without its potential harms. It might even provide some health benefits.

NewsA simple blood test can predict Crohn’s disease years before symptoms appear
Researchers have shown a blood test can predict Crohn’s disease years before symptoms appear, opening the doors to early diagnosis and potentially prevention. The test measures a person’s immune response to flagellin, a protein found on gut bacteria.
