NewsMicrobially synthesized bioplastic may solve marine plastic pollution problem
Researchers have demonstrated a new eco-friendly plastic that decomposes in deep ocean conditions. In a deep-sea experiment, the microbially synthesized poly(d-lactate-co-3-hydroxybutyrate) (LAHB) biodegraded, while conventional plastics persisted.

NewsBacteriostatic activity and mechanism of minerals containing rubidium
A new paper on traditional Chinese medicine outlines the bacteriostatic activity and mechanism of minerals containing rubidium (MCR).

NewsDisease-causing bacteria can deal with stink as long as they get a meal
Bacteria that cause intestinal infections typically avoid a stinky chemical — one that can kill them at high enough concentrations — inside human intestines, but they may actually swim toward it when a hearty meal is the reward.

NewsAI finds hundreds of potential antibiotics in snake and spider venom
Researchers used a deep-learning system to sift through a database of more than 40 million venom encrypted peptides (VEPs). In a matter of hours, the algorithm flagged 386 compounds with the molecular hallmarks of next-generation antibiotics.

NewsFlightpath Biosciences licenses microbiome-sparing antibiotic developed at Illinois
Flightpath Biosciences, Inc., has licensed a class of antibiotics developed at the University of Illinois Urbana-Champaign. The original antibiotic agent, lolamicin, effectively treated bacterial infections in animal models of disease without wiping out beneficial gut microbes.

NewsMultiresistant intestinal bacteria: Displacement through food competition
Researchers made use of food competition to figure out how potentially dangerous multi-resistant bacteria could be effectively removed from the gut before reaching the bloodstream and causing serious problems.

NewsGreen light activates this antibiotic only where it’s needed
To make a more efficient antibiotic treatment, researchers have modified penicillin so that it’s activated only by green light. In early tests, the approach precisely controlled bacterial growth and improved survival outcomes for infected insects.

NewsNew study reveals global warming accelerates antibiotic resistance in soils
A new international study has revealed that climate change is accelerating the rate of development and global abundances of antibiotic resistance bacteria in soils.

NewsNew source of natural antibiotics hidden within our own proteins identified
A team of scientists has identified a new type of antimicrobial peptides (AMPs) found in human proteins that are capable of selectively eliminating multidrug-resistant bacteria, particularly of the gram-negative type, responsible for serious hospital acquired infections.

NewsResearchers reveal remarkable antimicrobial activity in hydrogen boride nanosheets
Hydrogen boride (HB) nanosheets represent an exciting new frontier in the search for technologies that can combat microbes in everyday settings. Researchers discovered that they exhibit excellent antibacterial, antiviral, and antifungal properties.

NewsCan gut microbes save patients from chemotherapy side effects?
Intestinal microbes that survive chemo can rid the gut of excess chemo drugs and produce a vitamin that helps to stem nausea, a new study reveals.

NewsCould nanoplastics in the environment turn E. coli into a bigger villain?
New research suggests certain nanoplastics may make foodborne pathogens more virulent. Nanoplastics with positively charged surfaces were more likely to cause physiological stress in E. coli O157:H7, making them pump out more Shiga-like toxin.

NewsScientists evaluate in-vitro activity of ceftazidime-avibactam against carbapenem-resistant gram-negative bacteria
Scientists explored the in-vitro activity of ceftazidime-avibactam (CAZ-AVI) in clinical isolates of carbapenem-resistant gram-negative bacteria collected at the outpatient, emergency, and inpatient departments of the Indus Hospital, Karachi.

NewsActivating ‘jumping genes’ speeds up bacterial evolution from decades to weeks
Scientists have developed a system to control and accelerate the evolution of changes in the bacterial genome structure, targeting small ‘jumping genes’, or DNA sequences known as insertion sequences.
-
NewsSlow-growing bacteria respond more sensitively to their environment
A new study reveals that the responsiveness of bacterial cells to environmental stimuli is directly linked to their growth rate: the slower cells grow, the more sensitively they respond. This increased sensitivity can give the cells a crucial survival advantage.
-
NewsBiological patterns: Stability through protein reservoirs
Biophysicists have figured out how bacteria form robust patterns despite changing environmental conditions and fluctuating protein concentrations.

NewsBacteria deployed as living test tubes to study human gene mutations
Bioengineers have developed a new simple approach to rapidly check on human gene changes and also screen chemicals as potential drugs by turning everyday bacteria into living test tubes.
-
NewsBacteria use ancient war trick to outsmart viruses – and it could help us fight superbugs
Scientists have discovered a new type of immune defense in E. coli bacteria that turns viral infection machinery against the virus itself. They’ve named it Kongming after the Chinese military strategist who famously used enemy weapons to defeat his foes.

NewsGlycan-coated magnets: A game-changer for safer food supply chains
A new method using glycan-coated magnetic nanoparticles (gMNPs) is poised to change the way we detect foodborne pathogens like Escherichia coli and Salmonella in complex food matrices such as melons, lettuce, and raw chicken.

NewsNovel breath test shows promise for diagnosing and monitoring bacterial infections
A new, non-invasive breath test has emerged as a potential breakthrough for rapidly diagnosing bacterial infections and tracking treatment effectiveness.
