NewsPeptide study paves path toward new weapon against antibiotic-resistant bacteria
New research into antimicrobial peptides, small chains of amino acids able to damage bacterial cells, shows why some peptides are more effective at doing that and also why some cells are more vulnerable.

NewsCould bacteria help fix the smoky taste of wildfire-tainted wine?
New laboratory experiments show that a bacterium that lives on grape plants can break down guaiacol—an unpleasant-tasting substance which ruins wines made from grapes exposed to wildfire smoke.

NewsEngineers use bacterial nanowires to create first artificial neurons that could directly communicate with living cells
Engineers have created an artificial neuron with electrical functions that closely mirror those of biological ones. Using protein nanowires synthesized from electricity-generating bacteria, the discovery could herald immensely efficient computers built on biological principles.

NewsBacteria transform waste polystyrene into nylon precursors
Scientists have succeeded in getting bacteria to break down the molecular building blocks of polystyrene and convert them into useful chemicals.

NewsSome plants can make their own fertilizer - scientists say they learned it more than once
In a new study, scientists show that chemical receptors that plants use to recognize nitrogen-fixing bacteria have developed the same function independently on at least three separate occasions through a process called convergent evolution.

NewsSummer studentship: Eoin probes medicine-microbiome interactions using in vitro gut model
Eoin McKernan reports back on his AMI-sponsored summer studentship which focused on the relationships between the gut microbiome and the metabolism of variable response drugs.

News‘Alarming’ rise in newborn babies with antibiotic-resistant infections, researchers find
Researchers are calling for an urgent overhaul of diagnostic and treatment guidelines for infections in newborn babies, after a study revealed frontline treatments for sepsis are no longer effective to treat the majority of bacterial infections.

NewsBiogas slurry boosts biochar’s climate benefits by reshaping soil microbes
A new study finds that pairing biochar with biogas slurry, a nutrient-rich liquid fertilizer from biogas production, can reshape soil microbial communities and significantly alter emissions of carbon dioxide (CO₂), nitrous oxide (N₂O), and methane (CH₄).

NewsNew clues in how plant microbiomes protect against bacterial speck disease
A new study gives new clues on how a tomato plant’s microbiome can be used to combat the bacterial speck pathogen. Researchers found populations of Xanthomonas and Pseudomonas bacteria on the plants that had developed a resistance against bacterial speck.

NewsNatural antimicrobial drugs found in pollen could help us protect bee colonies from infection
Pollen gathered by honeybees contains antimicrobial-producing bacteria that protect the hive against disease, a new study reveals. The same beneficial bacteria occur in pollen stores of honeybee colonies and on pollen of nearby plants.

NewsScientists reveal functional RNA splitting mechanism behind origin of Type V CRISPR systems
Researchers have uncovered the molecular innovation that led to the origin of Type V CRISPR-Cas immune systems. Their findings show that the functional splitting of transposon-derived RNAs was the critical innovation driving the emergence of Type V CRISPR-Cas immunity.

NewsDeadly pathogens found in commercial raw cat foods
An analysis of commercial raw cat foods detected disease-causing microbes, including some that are resistant to antibiotics, creating risks for both pets and their owners, according to a new study.

NewsStudy shows mucus contains molecules that block Salmonella infection
Researchers have identified mucins that defend against Salmonella and other bacteria that cause diarrhea. They now hope to mimic this defense system to create synthetic mucins that could help prevent or treat illness in soldiers or other people at risk of exposure to Salmonella.

NewsSuper-resistant bacteria found in wild birds at a rehabilitation center in Brazil
Researchers have found antibiotic-resistant bacterial clones in wild birds at a rehabilitation center. The identified Escherichia coli clones have been found in community- and hospital-acquired human infections worldwide, and were present in the intestinal tracts of a vulture and an owl.

NewsTwo-drug combination shows promise in helping heal chronic wounds
By adding small doses of a simple molecule called chlorate to standard antibiotics, researchers foundthe combination proved 10,000 times more effective at killing bacterial cells in the lab than single-drug antibiotics.
-
NewsGenetic culprits IDed in capture of 100 years of antibiotic resistance evolution
The genetic culprits responsible for the spread of multidrug resistance (MDR) in bacteria have been identified by new research mapping 100 years of bacterial evolution.
-
NewsNew mechanisms for bacterial motility and DNA transfer between bacteria decoded
Scientists have discovered a new family of signaling proteins, widespread in the bacterial kingdom and contributing to regulating bacterial motility and DNA uptake mechanisms.

NewsAtom-precise agriculture: The future of eco-friendly crop protection
Researchers have created a novel single-atom copper pesticide that addresses the critical limitations of traditional copper-based pesticides, acting against the rice pathogen Pantoea ananatis.

NewsNutrient storage and release in uninfected cells of soybean nodules support symbiotic nitrogen fixation in infected cells
A new study employed the symplastic movement tracer carboxyfluorescein diacetate (CFDA) to observe and model the transport and storage status of nutrients within nodules.
