A wearable patch developed by researchers at King Abdullah University of Science & Technology (KAUST) tracks levels of potent antibiotics such as vancomycin in the body in real time using microneedles coated in DNA molecules. According to doctoral student Yurii Tsyban, the platform aims to improve precision drug monitoring by continuously measuring concentrations in the … Read more
River-type drinking water sources generally carry higher threats involving antibiotics, resistant bacteria, and associated genes compared to reservoir options, based on research featured in Biocontaminant. Researchers investigated 13 representative water sources across the Poyang Lake basin, highlighting the importance of considering water source type when designing monitoring and pollution-control strategies. Water Source Types and Contamination … Read more
Microplastics act as mobile pollutant shuttles that carry toxic chemicals, microorganisms, and antibiotic resistance genes across environmental boundaries, according to a review published in Energy & Environment Nexus by researchers from Jiangxi Agricultural University. Rather than existing as isolated pollutants, these tiny plastic particles interact with organic contaminants and microbial communities, amplifying ecological risks across … Read more
Recurrent urinary tract infections affecting an estimated 400 million people globally may finally be treatable thanks to a lab-grown human micro-bladder that reveals how bacteria hide deep inside bladder tissue, according to a study published in Nature Communications by researchers at University College London, the University of Oxford, and the University of Leicester. The findings … Read more
A combination of omega-3 and low-dose acetylsalicylic acid (ASA) achieved clinical results comparable to antibiotics in treating severe periodontitis, according to a study published in the May issue of the Journal of Periodontology. Researchers affiliated with Albert Einstein Israelite Hospital, Guarulhos University, the University of Taubaté, and the Ribeirão Preto School of Dentistry at USP … Read more
Researchers at the University of Exeter discovered two new mechanisms for how the antibiotic doxycycline works against bacteria, including stacking molecules to block the ribosome exit channel and reconfiguring ribosomes into an inactive state. The findings, published in Nature Communications, reveal how the drug disarms pathogens like Coxiella burnetii and could guide the design of … Read more
Rapidly developing antibiotic resistance during severe lung infections can occur when patients acquire circular pieces of DNA called plasmids from transient environmental bacteria, according to researchers at the University of Washington School of Medicine. Publishing their findings in Nature Microbiology, the team reported that this gene transfer can cause pathogen resistance to jump more than … Read more
Researchers at King Abdullah University of Science and Technology (KAUST) have developed a wearable microneedle patch capable of continuously measuring drug concentrations in interstitial fluid and transmitting that data to a smartphone in real time. The device, which weighs 6.7 grams, aims to explore whether continuous monitoring could provide a more complete picture than periodic … Read more
Breakthrough in Antibiotic Resistance: Targeting Bacterial Enzymes How the Study Uncovered a New Approach Antibiotic resistance, a global health crisis linked to 4.7 million deaths in 2019, has seen a critical breakthrough. Researchers at Scripps Research discovered that disabling a bacterial enzyme called secreted antigen A (SagA) makes vancomycin-resistant Enterococcus faecium (VREfm) vulnerable to vancomycin. … Read more
Bacterial populations survive antibiotic treatments by working as a collective, utilizing membrane vesicles to share proteins that protect dormant cells from lethal drugs. According to a study published in the journal Science by researchers at Baylor College of Medicine, this cooperative behavior allows vulnerable bacteria to endure antibiotic stress, explaining why persistent infections are notoriously … Read more
