NewsTesting AI against public health’s existing tools
A new study found that AI chatbots made vaccine-hesitant parents more likely to say they would vaccinate their children against HPV, but did not outperform materials from government health agencies, whose effects also lasted longer.

NewsAll-new lab in Kenya fills critical gap in wildlife health
Conservation stakeholders gathered to celebrate the official opening of the Laboratory in Northern Kenya (LiNK), an all-new veterinary diagnostic lab designed to fill a critical need for accessible diagnostic infrastructure in the remote region.

NewsAccelerating chikungunya vaccine development in Africa: Launch of the ACT-CHIK Project
Funded by the Global Health EDCTP3 Joint Undertaking, a new €15.3 million project coordinated by Institut Pasteur brings together seven partners across four continents to advance clinical trials and prepare for the manufacturing of a chikungunya vaccine in Africa.

NewsResearch team awarded NIH grant to study early immune determinants of human tuberculosis infection
A research team was awarded a 5-year, $3.8 million grant to study early immune responses in the lung and how they influence tuberculosis infection outcomes. The program focuses on how lung immune cells called macrophages influence the earliest stages of tuberculosis infection.

NewsNew noninvasive tool may allow early detection of dangerous intestinal disease in premature babies
A first-in-human study shows that a handheld probe placed gently on the belly of most fragile infants can reliably identify early stages of necrotizing enterocolitis.

NewsTime for an AI checkup: Flaw found in machine learning for sepsis treatment
Researchers found a flaw in many peer-reviewed studies using the AI method known as reinforcement learning as a theoretical guide for the treatment of sepsis. If these flawed systems for sepsis treatment were deployed in a healthcare setting, they would recommend either overtreatment or undertreatment in nearly half of patient states.

NewsMost cases of HIV persistence in blood following treatment explained by defective copies of the virus
A study based on blood samples strongly suggests that most persistent cases of viral detection, despite ideal HIV drug therapy, are not due to virus transmission or a rebound of active disease.

NewsScientists probe links between green space exposure, mental health and the nasal microbiome
Researchers recently studied associations among green space exposure, mental well-being, and the nasal microbiome—the microbes in a person’s nose. The analysis showed correlations among microbial signatures, time spent outdoors and positive mental well-being.

NewsFood insecurity linked to gut microbiome changes in children
A new study shows that food insecurity may leave a measurable impact on the gut microbiome of children. Children in food-insecure households had different gut microbiome profiles, including higher levels of Sutterella, which has been linked to poor dietary quality and intestinal inflammation.

NewsNew study provides insights into the control of photosynthesis
Scientists have discovered a previously unknown regulatory mechanism in plant photosynthesis in the unicellular green alga Chlamydomonas reinhardtii. It helps plants adapt to changes in light conditions. A crucial protein interaction at the interface between the two photosystems I and II controls the photosynthetic machinery.

NewsDrug-resistant bacteria found in homes from sewage overflow
A new study shows that sewage overflows in homes can expose people to bacteria that can make them sick, including antibiotic-resistant and multidrug resistant bacteria which can make infections difficult to treat.

NewsIndigenous mushroom transforms agricultural waste into food
An edible, seasonal mushroom in Eastern Nigeria has nutritional and therapeutic potential but is poorly researched. New research suggests that domestication of Lentinus squarrosulus using waste materials, specifically sawdust, could boost food production and provide employment opportunities for farmers and small businesses.

NewsNew tool quickly sequences hantavirus genome
The genetic diversity of hantavirus and the low levels of virus typically found in patient samples make sequencing its genome particularly challenging. Researchers have developed a new, effective, and low-cost way to carry out whole genome sequencing for hantaviruses.

NewsDentistry researchers testing oral bacteria transplants to cure bad breath
To rebalance the oral microbiome and cure chronic halitosis, researchers are embarking on a first-of-its-kind experiment. These clinical trials transplant bacteria and other microbes from healthy donors into patients with halitosis. If successful, the healthy microbiota will crowd out the bad and patients’ bad breath will improve.

NewsMaternal RSV vaccine cuts infant hospitalizations by 70%
A study has found that vaccination against respiratory syncytial virus (RSV) during pregnancy reduced the risk of hospitalization in young infants by nearly 70%. It provides early real-world evidence from U.S. clinical care, showing that administering one dose of the maternal RSV vaccine (RSVpreF vaccine) reduces hospitalization related to RSV in young infants.

NewsFlu drugs show promise against cognitive decline
A class of flu drugs may reduce cognitive decline and premature aging in people living with chronic viral infection. Scientists identified a new biological culprit: the degradation of protective sugar molecules in our bodies, known as glycans, that normally help keep inflammation in check.

NewsResearcher discovers single-celled organism that transforms into cannibalistic supergiant
Researchers have discovered a microscopic organism that can transform into a cannibalistic ’supergiant’ that drastically changes size, shape, and behavior, and abandons filter-feeding to hunt and consume their genetically identical relatives.
-
NewsResearchers combine bacteria and viruses to demonstrate a new way to fight cancer
Researchers have designed non-toxic Salmonella bacteria to deliver viruses that are safe to humans but potent against liver and pancreatic cancer tumors. Animal models treated with this combination of bacteria and viruses saw almost all their tumors eliminated and lived significantly longer.
-
NewsOrganized microbial ‘workforces’ keep Earth’s underground biosphere running
By studying life deep inside a former gold mine, scientists uncovered evidence that Earth’s hidden biosphere operates less like a random collection of microbes and more like an organized workforce. From site to site, the ecosystems were incredibly different from one another but largely stable through time.

NewsNew model could help track deadly viruses back to their source
A new predictive model could help scientists more efficiently identify the reservoirs of emerging zoonotic viruses and dangerous pathogens like Ebola that can spill over from animals into humans. It relies on detailed information collected on suspected reservoir species to identify key windows.
