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.

NewsFrom Asgard to Earth: tiny discoveries hold clues to life’s greatest leap
Stromatolites may hold insights into how complex life began. Researchers have identified a previously unknown microbe living in close partnership with another organism inside these ‘living fossils’.
-
NewsNative bacteria may break down dioxins without genetic modification
Researchers have demonstrated that native soil bacteria, when treated with decoy molecules, can degrade non-native compounds, including persistent pollutants such as dioxins, without genetic modification.
-
NewsTrial assesses safety and effectiveness of two new TB vaccines
Two new vaccines to prevent tuberculosis (TB) are safe for use in adults and children, but they do not offer protection against all forms of TB, finds a large trial from India.
-
NewsHow cholera bacteria swap defenses against viruses
To survive viral attack, bacteria equip themselves with antiviral immune systems. Vibrio cholerae carries a large genetic element called a sedentary chromosomal integron (SCI). A new study investigates whether the SCI might capture gene cassettes from genetic material entering the cell from the outside.

NewsCould your housemates be changing your gut bacteria?
Living with friends may quietly be altering your gut bacteria - according to a new study. Research on a colony of tiny island birds reveals they share more of their gut bacteria with the birds they spend the most time with.

NewsHidden ocean feedback loop could accelerate climate change
Scientists have uncovered a key mechanism behind methane production in the open ocean. Their research indicates that this mechanism could intensify as the planet warms, providing an alarming feedback loop for global warming.

NewsTropical trees are more neighborly, study suggests
Tropical trees are better neighbors than trees in temperate forests, according to a new study. Trees growing closer to the equator have more positive interactions with their neighbors, which may help explain why tropical forests are home to so many tree species.
