Higher maternal selenium linked to lower streptococcal infection risk in children

Higher maternal selenium levels during pregnancy were associated with a lower risk of streptococcal infections in children, suggesting a potential protective effect.

Newly discovered Cat1 protein halts viral infections by depleting cellular fuel

Every living creature on Earth needs to protect itself from things that would do it harm. Bacteria are no different. And despite their relative simplicity, they deploy remarkably savvy defensive strategies against viral invaders.

New gene editor evoCAST enables precise insertion of complete genes

Ask scientists what gene editing tool is most needed to advance gene therapy, and they'd probably describe a system that's now close to realization in the labs of Samuel Sternberg at Columbia University Vagelos College of Physicians and Surgeons and David Liu at the Broad Institute of MIT and Harvard.

Black tea kombucha reduces harmful gut microbes linked to obesity

Regular consumption of black tea kombucha for eight weeks beneficially shifted gut microbiota composition in both normal-weight and obese adults.

New glycopeptide antibiotic discovered to combat resistant bacteria

An international team of researchers, led by the University of Vienna and the Helmholtz Institute for Pharmaceutical Research Saarland, has discovered saarvienin A, a new type of glycopeptide antibiotic.

New device offers real time breastfeeding data for parents and clinicians

While breastfeeding has many benefits for a mother and her baby, it has one major drawback: It's incredibly difficult to know how much milk the baby is consuming.

Skin microbiome plays active role in sun protection and immune balance

The skin microbiome plays an important role in health and disease. Researchers have now 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.

X-ray dose rate found to influence bacterial sterilization efficiency

Radiation sterilization technology destroys the DNA and cellular structures of bacteria and microorganisms using electromagnetic waves with far higher energy than ultraviolet radiation.

University of Tokyo team accelerates bacterial genome evolution in the lab

The genome structure — how genes are organized within DNA sequences in an organism — is fundamental to the processes and functions of organisms.

Gum disease bacterium linked to increased risk of atrial fibrillation

Tempted to skip the floss? Your heart might thank you if you don't. A new study from Hiroshima University (HU) finds that the gum disease bacterium Porphyromonas gingivalis (P. gingivalis) can slip into the bloodstream and infiltrate the heart.

MicroRNA breakthrough offers hope for dental bone regeneration

Dental caries, or tooth decay, is a common oral health condition that often causes significant pain and discomfort and may even lead to tooth loss.

Study uncovers how co-infection by two bacteria suppresses immune response

The incidence of infection by Mycobacterium abscessus, is increasing in patients with cystic fibrosis, chronic obstructive pulmonary disease (COPD), and other chronic pulmonary diseases, leading to an accelerated lung function decline.

New molecule offers hope for chlamydia treatment

Researchers at Umeå University, Sweden, and Michigan State University, USA, have discovered a type of molecule that can kill chlamydia bacteria but spare bacteria that are important for health.

Scientists build world's most accessible gut bacteria collection to unlock health and disease clues

Researchers have developed the Human Intestinal Bacteria Collection (HiBC), comprising 340 gut bacterial strains from 198 species, including 29 newly described taxa, made publicly available for functional microbiome research.

Air pollution reshapes children’s nasal microbiome and reduces diversity in winter

A new study from Milan reveals that short-term exposure to air pollutants like black carbon and VOCs significantly alters the nasal microbiota of school-aged children. These changes vary by season, with winter exposure reducing microbial diversity and favoring potentially pathogenic bacteria.

Most deadly drug-resistant infections in poorer countries go untreated, study shows

A new modelling study reveals that only 7% of carbapenem-resistant Gram-negative (CRGN) bacterial infections in eight LMICs receive effective antibiotic treatment. This stark undertreatment poses a major threat in the global fight against antimicrobial resistance (AMR).

New insights into bacterial division through engineered protein control

The Min protein system prevents abnormal cell division in bacteria by forming oscillating patterns between the ends of a cell ("poles"). Despite decades of theoretical work, predicting the protein concentrations at which oscillations start and whether cells can maintain them under different conditions has been a challenge.

Can your diet slow skin aging? New review reveals what helps and what harms

Scientists reviewed recent studies and found that antioxidant-rich diets help slow skin aging, while high intake of refined sugars and trans fats accelerates it. A balanced, nutrient-dense diet may be a practical way to protect skin health and delay visible signs of aging.

Breakthrough in labeling TB glycans could lead to faster diagnosis

Tuberculosis, the world's deadliest infectious disease, is estimated to infect around 10 million people each year, and kills more than 1 million annually. Once established in the lungs, the bacteria's thick cell wall helps it to fight off the host immune system.

New rifamycin drugs fight antibiotic-resistant lung infections more effectively

Researchers have developed next-generation rifamycin analogs that effectively kill both replicating and nonreplicating Mycobacterium abscessus while minimizing drug-drug interactions. Lead candidates UMN-120 and UMN-121 showed superior efficacy to current treatments in mouse models and retained potency against M. tuberculosis.
