Tapping the power of cryo-ET to visualize how molecular machines interact inside cells

Scientists have often thought of cells as small bustling cities with parts that resemble factories, power grids, and shipping systems.

Existing drug helps bladder cells destroy hidden urinary tract infections

Urinary tract infections, or UTIs, are among the most common bacterial infections, caused mostly by the uropathogenic bacterium Escherichia coli. But even after antibiotic treatment, a large number of patients experience another UTI.

New tool to mutate phages boosts the fight against superbugs

A new tool to mutate bacteriophages – viruses that infect bacteria – provides a "big leap" forward in both our understanding of how they function, and our ability to harness their full potential.

Gut bacteria metabolites directly extend the lifespan of host flies

Gut microbiota influences multiple aspects of host physiology, including metabolic and immune functions.

First foods bring an early functional shift in the infant gut microbiome

Researchers analyzing paired gut microbiome samples from 125 Irish infants found that complementary feeding was associated with early changes in microbial composition and metabolic potential, including an increased capacity for complex carbohydrate metabolism. Breastfeeding duration was more closely associated with microbial community development than the timing of solid-food introduction, while formula-fed infants showed more extensive functional pathway changes after solids were introduced.

Could a parent’s hospital job shape a child’s nasal microbiome?

A pilot study of 37 families found that children with healthcare-worker parents had lower nasal microbial diversity, with the largest differences among children whose two parents worked in healthcare. Porphyromonas was significantly less abundant, while Neisseria showed a similar non-significant pattern, but the cross-sectional study cannot establish causality or determine whether these microbiota differences affect health.

Stalled gut microbiome development triples risk for type 1 diabetes in children

Type 1 diabetes affects more than 9 million people worldwide, including 1.8 million children and adolescents.

Researchers mine cobra toxins to uncover a membrane-disrupting antimicrobial peptide

Researchers combined toxin sequence mining with machine learning and deep-learning prediction tools to identify and experimentally test 14 antimicrobial peptide candidates derived from cobra cardiotoxins. Most candidates showed limited antibacterial potency, while CTX-p5 displayed moderate membrane-disrupting activity, revealing both the potential and current limitations of computationally guided venom peptide discovery.

Weill Cornell Medicine receives $17.4 million grant to shorten tuberculosis treatment

Researchers at Weill Cornell Medicine have received a $17.4 million, five-year grant from the National Institute of Allergy and Infectious Diseases to discover new approaches to shorten tuberculosis (TB) treatment, potentially making it easier for patients to complete therapy.

Can AI find drugs to fight infection?

Streptococcus pneumoniae is a bacterial pathogen that causes life-threatening infections, including pneumonia and meningitis.

Genetically modified bacteria create protective shield against Salmonella attacks

The mammalian gut microbiome is teeming with a delicate balance of bacteria and the viruses that keep them in check, called bacteriophages, or phages.

Cannabis-derived nanovesicles showed early antitumor potential in mice

Researchers developed a Cannabis sativa hairy root culture system that produced stable plant-derived nanovesicles capable of promoting dendritic cell maturation and activating T-cell responses through TLR2- and TLR4-associated signaling. Oral administration also restored selected immune responses in immunosuppressed mice and suppressed tumor growth in an E.G7 lymphoma model, providing preliminary evidence for their immunomodulatory and antitumor potential.

FDA outlines key tips for safe tampon usage

If you use tampons during your period, it's important to know how to use them safely, and to understand how the U.S. Food and Drug Administration evaluates their safety and effectiveness.

Bacterial strains determine pneumonia and meningitis risk from air pollution

Air pollution leads to different risk of bacterial pneumonia, sepsis, and meningitis, depending on the subtype of bacteria a person has, new research suggests.

Nanoparticle platform reliably detects true cases of antibiotic allergy

A multidisciplinary scientific team at the University of Malaga has developed a new technology based on magnetic nanoparticles that enables precise, rapid and reliable diagnosis of allergy to beta-lactam antibiotics, including amoxicillin and other penicillins.

Refined starch activates immune pathways after low-carb weight loss

After substantial weight loss on a very-low-carbohydrate diet, participants who switched to a diet rich in refined starch showed greater activation of circulating immune and metabolic pathways than those who continued the low-carbohydrate diet or consumed a high-carbohydrate diet rich in added sugar. Mouse experiments suggested that activation of the complement immune pathway may help explain the inflammatory response associated with starch intake.

Gut microbiome may reveal inflammation and future disease risk better than age

Gut microbiota composition explained more variation than chronological age in nearly all inflammatory cytokines and most physiological measures examined, with specific microbial profiles linked to markedly different patterns of inflammation across adulthood. People with the Bacteroides 2 enterotype showed an inflammaging-like profile decades earlier than other groups and had a higher risk of subsequent disease, while a high-diversity microbiota profile was associated with lower inflammation and reduced disease incidence.

C. diff uses dual-threat sensing system to survive gut stress

The pathogen Clostridioides difficile (C. diff) - a leading cause of hospital-acquired infections - must contend with a variety of threats inside the harsh environment of the gut to survive and grow.

Gut infection leaves long-lasting immune ‘memories’ at the brain’s borders in mice

In mice, intestinal infections reshaped dural CD4+ T-cell populations and seeded the brain’s outer meningeal border with antigen-specific memory cells that persisted for months and mounted rapid recall responses to bloodborne antigens. Oral priming was associated with reduced Salmonella spread to the brain and modest cross-protection in an engineered shared-antigen Candida model, although the researchers could not definitively prove that dural CD4+ T cells alone caused the protection.

Study shows how the microbiome shapes lung cancer immunotherapy outcomes

Despite the revolutionary impact of immune checkpoint inhibitors on cancer therapy, 60% to 80% of patients with NSCLC still show suboptimal responses.
