NewsStudy finds blood pressure drug effective for treating antibiotic-resistant bacteria
A new study reports that a drug used to lower blood pressure could also be the basis of a promising new treatment for methicillin-resistant Staphylococcus aureus (MRSA). Candesartan cilexetil not only killed MRSA bacteria at different growth stages, but also reduced the formation of biofilms.

NewsLong-term cure rates for multidrug-resistant tuberculosis much better than expected
A new national cohort study from Latvia provides important insights into the treatment of multidrug-resistant tuberculosis (MDR-TB). The study shows that long-term disease-free survival rates are significantly higher than previous standard indicators suggest.

NewsAncient viruses serving as gene delivery couriers to help bacteria resist antibiotics
Research has shed important new light on the enemies-turned-allies that allow bacteria to exchange genes, including those linked to antimicrobial resistance (AMR).

NewsDon’t build the engine, grow it: biohybrid miniature robots using living organisms
By fusing living organisms like bacteria, algae, and insects with synthetic payloads, researchers are creating living biohybrid miniature robots that self-fuel, self-repair, and navigate environments that would paralyze a rigid silicon chip.

NewsFoxes and birds could be ‘early warning system’ to survey spread of antibiotic resistance into ecosystems
Wildlife monitoring could alert us to the spread of highly antibiotic resistant bacteria into unexposed ecosystems, highlighting a potential public health strategy.

NewsColor test ‘sniffs out’ dangerous staph strains fast
Researchers have developed a rapid colour-changing test that can distinguish between different strains of golden staph, including those likely to be virulent and antibiotic resistant.

NewsAncient tooth reveals the bacterium responsible for scarlet fever was not introduced to the Americas by Europeans
A research team has identified the Streptococcus pyogenes bacterium in a pre-Columbian Bolivian mummy and, for the first time, reconstructed the genome of this centuries-old pathogen.

NewsResearchers synthesize photosynthetic molecule found in bacteria
Researchers have successfully synthesized bacteriochlorophyll a, a photosynthetic pigment found in bacteria which absorbs infrared light. The work represents the first chemical synthesis of this molecule and could give scientists deeper insights into photosynthetic function and photosynthetic energy.

NewsPoor hygiene and food handling practices increase the risk of bacterial outbreaks in Brazilian households
A significant number of Brazilians engage in improper food hygiene and handling practices at home. Examples include washing meat in the kitchen sink and failing to properly wash vegetables.

NewsAs syphilis cases rise, study links infection with higher risk of stroke, heart attack and other serious cardiovascular problems
Adults with later-stage syphilis are more likely to develop major cardiovascular problems – including stroke, heart attack or aortic aneurysm – than similar patients without the infection. The increased risk is primarily found in those whose infection progressed longer than a year.

NewsSelf-propulsion or slow diffusion: How bacteria, cells, and colloids respond to stimuli
One enables them to quickly leave an environment; the other helps them move toward where they are needed. In microorganisms, as well as in artificial structures, these are the movements triggered in response to incoming and outgoing signals.

NewsGut microbiome serves as key driver for bacterial infection outcomes for fatty liver disease
Researchers found that metabolic dysfunction–associated steatotic liver disease dramatically worsens outcomes following infection with Vibrio vulnificus, a potentially life-threatening foodborne bacterium commonly associated with seafood consumption.
-
NewsHow soil microbes adapt to life in lakes
Researchers have analyzed the genome of bacteria living in Lake Zurich to conclude that microbes employ two different strategies to colonize new habitats. Some acquire new traits – but others reduce the size of their genome and lose some functions in order to successfully move to a new home.

NewsA built-in ‘hairpin’ prevents rogue CRISPR RNAs
A new study reveals that many CRISPR-Cas13 systems utilize an RNA to prevent the formation of extraneous CRISPR RNA. With the first repeat, this protective RNA forms a stable structure resembling a hairpin. It points to a remarkable case of convergent evolution.

NewsAI spots hidden behavior patterns in self-organizing bacteria
A custom-built artificial intelligence system has helped to uncover how bacterial communities organize themselves, showing that the earliest moments of a biological transition carry far more information than previously considered.

NewsA bacterium from bumblebees can produce vitamin B2 in soya drinks
Researchers have developed a new method that can reduce the time needed to find new bacteria for fermentation. They have now identified a bacterium that can be used both for acidification and to increase the vitamin B2 content of soya drinks.

NewsUltrasensitive test reveals evidence of previously undetected tuberculosis in Boston Hospital patients
Researchers have discovered an unexpectedly high prevalence of Mycobacterium tuberculosis DNA (TB DNA) in patients hospitalized in Boston, suggesting that tuberculosis disease may be significantly underdiagnosed in the United States.
-
NewsNew bite-sized CRISPR molecule may open doors for therapeutic genome editing
The safest, most accurate gene-editing tools don’t fit inside viral delivery mechanisms that could target them to specific cell types or tissues inside the human body. Researchers have developed a smaller pair of “molecular scissors” for gene editing that could make site-specific delivery within the body possible.

NewsShorter antibiotic courses show similar outcomes to longer use for some pneumonia patients
A multicenter target trial emulation found that for eligible patients hospitalized with community-acquired pneumonia (CAP), health outcomes were similar whether they received a three- to four-day course of antibiotics or a course lasting five days or more.

NewsScientists discover the antibacterial potential of ‘hero’ Korean skincare ingredient
Fans of Korean skincare may be familiar with ‘hero ingredient’ Madecassic acid for its skin-soothing properties, but researchers have revealed its greater potential for use in the battle against antibiotic resistance.
