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.

NewsComplex life developed earlier than previously thought, study reveals
New research indicates that complex organisms evolved long before there were substantial levels of oxygen in the atmosphere, something which had previously been considered a prerequisite to the evolution of complex life.

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.

NewsResearchers use ‘brain-on-a-chip’ to revolutionize fight against deadly encephalitis viruses
A transparent chip no larger than a stick of gum is helping scientists transform the way researchers study the human brain and develop treatments for some of the world’s deadliest viruses.

NewsSingle-cell movies reveal how host physiology sets phage success - and how to time therapies
A new study outlines how an innovative imaging platform can be used to help uncover the reasons why phages succeed or fail when used to target bacterial infections.

NewsNew test distinguishes vaccine-induced false positives from active HIV infection
A new device correctly identified those with active HIV-1 infection 95% of the time and those without active infection but with vaccine-induced molecules that could trigger a false positive, 98% of the time.

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.
