NewsDesigner microbe shows promise for reducing mercury absorption from seafood
Scientists who inserted DNA-encoding methylmercury detoxification enzymes into the genome of an abundant human gut bacterium found it detoxified methylmercury in the gut of mice and dramatically reduced the amount that reached other tissues.

NewsStudy of facial bacteria could lead to probiotics that promote healthy skin
Researchers have revealed the dynamics of interactions between two dominant skin bacterial species in more detail than previously possible, shedding light on when and how new bacterial strains emerge on the skin of the face.

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.

NewsNovel compound inhibits the growth of tumor-associated Fusobacteria
Researchers seeking ways to eliminate fusobacteria in carcinomas have made an unexpected discovery: their control compound, FUS79, which did not target a specific transcript, exhibited strong activity against five fusobacterial strains without affecting other tested bacterial species.

NewsResearchers reveal how human genetics and intratumoral microbiota affect colorectal cancer
A study shows that the single-nucleotide polymorphism (SNP) rs2355016—a tiny DNA change that some people carry—affects how intratumoral microbiota adhere to tumor cells, promoting colorectal cancer progression.

NewsBroader antibiotic use could change the course of cholera outbreaks, research suggests
Disease modeling research suggests that, for some cholera outbreaks, prescribing antibiotics more aggressively could slow or stop the spread of the disease and even reduce the likelihood of antibiotic resistance.

NewsFungi dwelling on human skin may provide new antibiotics
Researchers have uncovered a molecule produced by yeast living on human skin that showed potent antimicrobial properties against a pathogen responsible for a half-million hospitalizations annually in the United States.

NewsA hidden control center: How bacteria regulate their attack strategies
Researchers have discovered that a key bacterial protein, CsrA, gathers in a droplet-like structure inside cells to control when and how bacteria activate their disease-causing genes.

NewsBacteria’s mysterious viruses can fan flames of antibiotic damage, according to new model
Researchers built a model that allows them to diminish phage communities from a mouse gut microbiome — and then bring them back — without affecting the bacteria. A test run found evidence that phages may increase gut bacteria’s sensitivity to antibiotics.

NewsAntibiotic resistance: Towards drugs to disarm bacteria
Researchers have identified the mutation frequency decline (Mfd) protein, a virulence factor produced by all bacteria and essential for them to resist the host immune system. This protein has the additional function of promoting spontaneous and random mutations.

NewsTick researchers identify new strain of rickettsia bacteria that causes spotted fever infections in humans
In a residential backyard in Maine, researchers stumbled upon a surprise finding: rabbit ticks harboring a new type of bacteria related to a group of pathogens that can cause sometimes life-threatening spotted fever rickettsioses (SFR) infections in humans.

NewsNo more copy-pasting: DNA base editing for better Lactobacillus strains
Scientists were able to edit the DNA of Lactobacillus strains directly without a template from other organisms. This technique is indistinguishable from natural variation and enabled them to create a strain that doesn’t produce diabetes-aggravating chemicals.

NewsOpen benchmarking of CycloneSeq™ for complete bacterial genomes
Benchmark data and analysis of new CycloneSEQ using novel nanopore sequencing technology demonstrates the ability to sequence complete bacterial genomes.

NewsSugar-mimicking molecule central to virulence of a common crop disease, study finds
A strain of Pseudomonas syringae manipulates plants by producing a substance called glycosyrin to suppress the immune response. New research shows that glycosyrin does this by mimicking galactose, acting like a wolf in sheep’s clothing.

NewsMicroorganisms employ a secret weapon during metabolism
Microorganisms have evolved a variety of methods for fixing carbon. Researchers investigated the methods that are utilized at extremely hot, acidic and sulfur-rich hydrothermal vents in shallow waters off the island of Kueishantao, Taiwan.

NewsAntibiotic-resistant Escherichia albertii on the rise in Bangladeshi chicken shops
Researchers have detected alarming rates of Escherichia albertii in retail chicken meat in Bangladesh. Their findings show extensive contamination and significant antimicrobial resistance, underscoring the potential risks to public health.

NewsThe very first structural images of a tuberculosis-fighting virus
Scientists have used advanced imaging techniques to provide a detailed look at how a tiny virus, known as a phage, invades Mycobacteria. The research could pave the way toward phage-based treatments for antibiotic-resistant mycobacteria.

NewsDr. Sabine Ehrt named Chair of the Department of Microbiology and Immunology at Weill Cornell Medicine
Dr. Sabine Ehrt, an internationally renowned leader in tuberculosis research, has been appointed chair of the Department of Microbiology and Immunology at Weill Cornell Medicine.

NewsLiving fungus-based building material repairs itself for over a month
Engineers have developed a building material that uses the root-like mycelium of a fungus and bacteria cells. They show that it is capable of self-repairing and could eventually offer a sustainable alternative for high-emission building materials like concrete.
