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.

NewsResearchers uncover the secret route of prostate infections
A research team has developed a “mini prostate” organoid model using adult stem cells. Using this model, the scientists could follow a bacterial prostatitis infection step by step under controlled conditions and identify exactly how the bacteria attack.

NewsClinical trial in Ethiopia targets the trachoma scourge
A new study documents the outcomes of an evaluation of fluorometholone as adjunctive medical therapy for trachomatous trichiasis surgery, part of an initiative to better prevent blindness and improve quality of life for those affected.

NewsScientists decode tree genome to unlock terpenoid-based disease resistance
Researchers reported a chromosome-scale genome and multi-omics analysis of a Lauraceae medicinal tree. The study reveals how specific terpene synthase (TPS) genes contribute to antimicrobial compound production and enhanced resistance to plant diseases.
-
NewsResearchers revive failing antibiotics with two-faced Janus nanoparticles
Researchers have restored the power of failing antibiotics by combining them with two-sided nanoparticles, ultra-small building blocks of materials less than 100 nanometers across. The nanoparticles showed a remarkable ability to compromise bacterial cell walls, leaving them vulnerable to attack.

NewsA tug-of-war explains a decades-old question about how bacteria swim
Whether a bacterium’s tail spins clockwise or counterclockwise was previously thought to depend on a ‘domino effect’ among proteins inside the tail. However, new research proposes that a tug-of-war is the deciding factor.
-
NewsTraditional herb offers new hope for antibiotic-free pig farming
A new review highlights that Houttuynia cordata extract could serve as a multifunctional natural substitute for antibiotics in swine production. Plant-derived flavonoids, volatile oils, and polysaccharides suppress pathogens including Salmonella, PRRSV, and Streptococcus suis.

NewsHow Mtb safeguards itself from foreign DNA
Researchers have discovered how a key protein in the tuberculosis bacterium helps protect it from the influence of foreign DNA inserted into its genome. Understanding how this protein – called Lsr2 – functions could help develop drugs that target it, thereby aiding in the fight against TB.
-
NewsNew test shows which antibiotics actually work
Drugs that act against bacteria are mainly assessed based on how well they inhibit bacterial growth under laboratory conditions. A critical factor is whether the active substances actually kill the pathogens in the body. Researchers have presented a new method for measuring how effectively antibiotics kill bacteria.

NewsTB harnesses part of immune defense system to cause infection
Scientists have made a discovery that helps explain why humans and animals are so susceptible to contracting tuberculosis – and it involves the bacteria harnessing part of the immune system meant to protect against infection. They team discovered that MTB survives within the cells of its host by targeting Dectin-1.

NewsBiodegradable and conventional plastics shape very different antibiotic resistance risks in river microbiomes
Biodegradable plastics are not always safer for rivers and oceans, according to a new study that tracked how different plastics change the risk of antibiotic resistant bacteria over time in a real river.
-
NewsMelting glaciers may release hidden antibiotic resistance into vital water sources
Researchers report that glaciers act as long-term reservoirs of antibiotic resistance genes. Once released by glacier melt, these genes can enter rivers, lakes, and ecosystems that supply drinking water and support wildlife in polar and high-altitude regions.

NewsWhat causes some people’s gut microbes to produce high alcohol levels?
A study of people with a rare condition known as auto-brewery syndrome has found a link between gut microbes and symptoms of intoxication, pointing to new treatment strategies.

NewsVictoria’s Secret grant backs cutting-edge ovarian cancer research
Promising ovarian cancer research by Melanie Rutkowski, PhD, at the University of Virginia Comprehensive Cancer Center has won $700,000 in support from the Victoria’s Secret Global Fund for Women’s Cancers in partnership with Pelotonia and AACR, the American Association for Cancer Research.
