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.

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.

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.

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.

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.

NewsCedars-Sinai and Exobiosphere partner to launch biomedical research aboard the Haven-1 Space Station
Cedars-Sinai is partnering with Exobiosphere, a company that has developed scientific hardware to automate biomedical research in space and on Earth, and will send experiments to Haven-1, set to become the world’s first commercial space station.

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.

NewsFish freshness easily monitored with a new sensor
Researchers have developed a simple, effective electronic device that quickly measures a compound that forms when decomposition starts. The prototype sensor can determine how fresh a fish is in less than two minutes.

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.

NewsCommon water pill may help HIV medicines work faster and reduce inflammation, early study suggests
Adding a readily available diuretic to standard HIV therapy appears to reduce circulating virus by four-fold, a new study shows. Researchers treated HIV-infected mice with human immune cells with first‑line antiretroviral therapy plus a long‑acting form of spironolactone.

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.
