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.

News‘Creeping catastrophe’: Climate change is driving global rise in infectious diseases, leading health experts warn
Infectious diseases such as malaria, dengue, and tuberculosis are considered to pose as great a challenge to global health as new or emerging pathogens, according to a study. Participants reported that climate change, poverty, and drug resistance are combining to create an escalating health crisis.
-
NewsStudy unravels the fungi-cancer connection
A growing body of evidence indicates that the microbiome within the gut and tumors significantly influences cancer initiation, progression, and treatment response. Current research primarily focuses on bacteria, whilst the role of fungi is only now gaining attention.

NewsToxoplasmosis: How a deadly parasite infects its host cells
Researchers have discovered how the parasite Toxoplasma gondii builds a specialised structure that allows it to move and invade host cells. They identified two proteins that control how the conoid complex is assembled - this acts like an engine for movement and cell-invasion.

NewsBiochar boosts hydrogen and methane yield in next-generation food-waste-to-energy systems
A research team has demonstrated that adding biochar to two-phase anaerobic digestion systems can significantly increase hydrogen and methane production from food waste, while maintaining system stability under high organic loading rates.

NewsAll life copies DNA unambiguously into proteins. Archaea may be the exception.
A study shows how a methane-producing member of the Archaea, interprets one three-letter sequence — normally a stop codon that signals the end of a protein — in two different ways, synthesizing two different proteins seemingly at random, though biased by conditions in the environment.
