NewsChemical structures of surface polysaccharides from Acinetobacter baumannii for glycoconjugate vaccines
Researchers provided a comprehensive analysis of the molecules that make up the protective layer of complex sugars on the surface of Acinetobacter baumannii - known as capsular polysaccharides (CPS) and lipopolysaccharides (LPS), and essential for the bacterium’s virulence.

NewsResearchers identify bacterial enzyme that can cause fatal heart conditions with pneumonia infections
Researchers have identified a bacterial enzyme that may be the reason some people get heart complications with pneumonia, while others do not. Since enzymes create chemical reactions to help bacteria survive, grow, and sometimes attack tissues, zmpB could become a target for future therapies.

NewsVolcanic eruptions set off a chain of events that brought the Black Death to Europe
Researchers have used a combination of climate data and documentary evidence to paint the most complete picture to date of the ‘perfect storm’ that led to the deaths of tens of millions of people, as well as profound demographic, economic, political, cultural and religious change.

NewsTo treat long COVID, we must learn from historical chronic illnesses, medical researchers say
Scientists and doctors have highlighted the importance of studying long COVID in the context of other post-acute infection syndromes or chronic illnesses. By analyzing historical accounts of other epidemics, researchers can gain important perspective on the effects of these chronic illnesses.

NewsMicrobiome of an entire country is mapped for the first time
An international research team has systematically mapped the microbiome of an entire country for the first time. More than 10,000 environmental samples from across Denmark were analyzed, resulting in an atlas of environmental microbiomes with unprecedented spatial resolution and functional depth.

NewsDo oral bacteria from tooth infections worsen diabetes risk?
A new study demonstrates that Porphyromonas gingivalis and its lipopolysaccharide are potent drivers of both periapical bone destruction and systemic metabolic dysfunction, acting through an IL-17–dependent inflammatory pathway.

NewsThe ship-timber beetle’s fungal partner: more than just a food source
Researchers studying the ambrosia fungus of the ship-timber beetle discovered that this fungus stores significantly more nutrients than other types of fungi. The beetle’s symbiotic fungus accumulates various phenolic substances from the wood in its mycelium.

NewsThe power of gut enzymes: why healthy eating affects everyone differently
Researchers have uncovered a mechanism that determines how our gut microbiome processes healthful plant compounds. The chemical cookbook of gut bacteria varies from person to person—and is often disrupted in chronic diseases.
-
NewsNew roadmap reveals how everyday chemicals and microbes interact to fuel antimicrobial resistance
A new perspective outlines an urgent scientific roadmap for understanding how common chemicals interact with microbial communities to accelerate the global crisis of antimicrobial resistance.

NewsScientists clarify how much metal in soil is 'too much' for people and the environment
A new review explains which laboratory tools, models and tests best capture the true bioavailability of heavy metals in soil and how regulators worldwide are starting to use them.

NewsMental health conditions may heighten liver cancer risk in veterans due to increased hepatitis C
Mental health conditions, especially alcohol use disorder and post-traumatic stress disorder (PTSD), significantly increase the likelihood of developing liver cancer among U.S. veterans living with cirrhosis of any cause.

NewsStudy shows common childhood virus can drive bladder cancer development
Tackling a common childhood virus could open the door to preventing bladder cancer, according to new research. The study suggests that a virus most people pick up in childhood can trigger the type of DNA damage that can lead to bladder cancer later in life.
-
NewsFamily dogs boost adolescent mental health through the microbiome
It’s no surprise that dogs benefit people’s mental health. Researchers point to a reason as to why: dogs prompt changes in the collection of microbes that live in and on our bodies, resulting in an increase in mental health.
-
NewsResearchers confirm new rickettsia species found in dogs
Researchers have confirmed that a species of Rickettsia first seen in dogs in 2018 is a new species of bacteria. The new species is associated with symptoms similar to those of Rocky Mountain spotted fever (RMSF) in dogs, but has not yet been found in humans.
-
NewsPlant ‘first responder’ cells warn neighbors about bacterial pathogens
Researchers have found that a subset of epidermal cells in plant leaves serves as early responders to chemical cues from bacterial pathogens and communicate this information to neighbors through a local traveling wave of calcium ions.
-
NewsAntibiotics could trigger immune response through gut microbiome metabolites
Researchers report how one of the most abundant gut bacteria responds to tetracyclines, a class of commonly prescribed antibiotics. Newly characterized signals released by the bacterium could aid the host’s immune response, inhibit pathogens and restructure the gut microbiome.
-
NewsAlgae show how to make two proteins from one messenger RNA
Scientists have uncovered a hidden feature of protein translation in green algae, offering a new perspective on the basic rules of gene expression.
-
NewsLight-sensitive microbial protein may herald new cancer therapies
Researchers used a mouse cancer model to show that tumors expressing Archaerhodopsin 3 shrink after exposure to green light.
-
NewsStudy links childhood vaccination to lower risk of drug-resistant bacteria
Children in Guatemala who received a common vaccine that helps prevent pneumonia were less likely to carry antibiotic-resistant bacteria, according to a new study examining whether rotavirus (RV) and pneumococcal (PCV13) vaccines reduce gut colonization by a group of bacteria.

NewsBlack carbon from wheat straw burning shown to curb antibiotic resistance spread in farmlands with plastic mulch residues
A new study reveals that black carbon formed during wheat straw burning can significantly reduce the spread of antibiotic resistance genes in soil and soybean crops, offering a promising strategy for safer and more sustainable farming in regions burdened by plastic mulch debris.
