NewsNew method developed to dramatically enhance bioelectronic sensors
In a breakthrough that could transform bioelectronic sensing, researchers have developed a new method to dramatically enhance the sensitivity of enzymatic and microbial fuel cells using organic electrochemical transistors (OECTs).

NewsImmunity against seasonal H1N1 flu reduces bird flu severity in ferrets, study suggests
Pre-existing immunity against seasonal H1N1 flu might help explain why most reported human cases of H5N1 bird flu in the U.S. have not resulted in lethal outcomes, suggests a new study.

NewsResearch reveals hidden risks from plastic-coated fertilizers in soil
A study focuses on the microplastic pollution generated by polymer-coated, control-release fertilizers, highlighting the need for biodegradable alternatives.

NewsNew insights into phage–bacteria interactions in the gut microbiome
Researchers studied the interactions between bacteria and phages within the gut microbiome and highlighted the significance of the phage community to shape the microbiome that contributes to host health and diseases.

NewsDesigning self-destructing bacteria to make effective tuberculosis vaccines
Preclinical studies have demonstrated a more effective tuberculosis (TB) vaccine through engineering bacteria to self-destruct and swiftly stops the infection on cue, which activates a more robust immune response.

NewsScientists build robot to track plant-fungal trade networks, revealing nature’s underground supply chains
New research uses advanced robotics to track the hyper-efficient supply chains formed between plants and mycorrhizal fungi as they trade carbon and nutrients across the complex, living networks that help regulate the Earth’s atmosphere and ecosystems.

NewsBacteria consumed by immune cells become part of the cell
Immune cells that eat bacteria in the body don’t stash them in specialized compartments as once thought, but turn them into critical nutrients that build proteins, create energy and keep the cells alive, according to a new study.

NewsBeacon Technology Solutions, Illinois Tech awarded grant to advance far-UVC disinfection research
Beacon Technology Solutions, with collaborators at Illinois Institute of Technology, has been awarded a grant to support a novel study on how Far-UVC technology can help mitigate the spread of infectious diseases in public spaces.

NewsHeat-stressed reefs may benefit from coral-dwelling crabs
A species of branching coral is able to recover from heat stress and wounds due to its mutualistic relationship with crabs in the Great Barrier Reef Corals, a new study shows. This evolutionary partnership will inspire coral reef restoration strategies in the future.

NewsUnexpected species-specific patterns in study of giraffe gut flora
The gut bacteria of giraffes are not primarily determined by what they eat, but by the species they belong to., according to a new study analysing the link between diet and gut flora in three giraffe species in Kenya. The study also provides new knowledge that can help secure the food supply of endangered giraffe species.

NewsHerpesviruses may contribute to Alzheimer’s disease via transposable elements
Researchers have outlined the pathway human herpes simplex virus-1 (HSV1) can use to contribute to Alzheimer’s disease in aging brains, and also share two FDA-approved, commercially available drugs that reverse this pathway in a laboratory setting.

NewsNew paper-based device boosts HIV test accuracy from dried blood samples
Scientists have trialled a more precise medical device to measure HIV viral loads by engineering a paper device with wax-printed patterns that create precise channels and collection spots, ensuring it consistently collects the same volume of blood.
-
NewsAs dengue spreads, researchers discover a clue to fighting the virus
Children who experience multiple cases of dengue virus develop an army of dengue-fighting T cells, according to a new study. Most children who experienced two or more dengue infections showed very minor symptoms—or no symptoms at all—when they caught the virus again.

NewsNew study calls for ethical framework to protect Indigenous genetic privacy in wastewater monitoring
Researchers have called for new ethical frameworks to protect Indigenous communities’ genetic privacy in the growing field of wastewater surveillance. The study examines how analysis of community wastewater raises significant privacy concerns for Indigenous populations.

NewsBackyard poultry face HPAI risk when migrating mallards stop to rest
Knowing where, when and for how long mallard ducks – natural carriers of avian influenza – stop and rest as they migrate can help predict the probability that they will spread bird flu to backyard poultry flocks, according to a new study.

NewsResearch suggests common viral infection worsens deadly condition among premature babies
Researchers say they found that infection with a common virus that can be transmitted from mother to fetus before birth significantly worsens an often-fatal complication of premature birth called necrotizing enterocolitis (NEC) in experiments with mice.
-
NewsScientists invent new drug candidates to treat antibiotic-resistant bacteria
Researchers designed a new family of antibiotics that’s a variation of an existing drug called vancomycin, which is used as a last resort for extremely ill patients. The new version of vancomycin targets, bonds to and renders inactive two different parts of a molecule on the surfaces of pathogenic bacteria.

NewsStealth virus: Zika virus builds tunnels to covertly infect cells of the placenta
Researchers have discovered that Zika virus in the placenta builds underground tunnels, a series of tiny tubes called tunneling nanotubes, that facilitate the transfer of viral particles to neighboring uninfected cells.

NewsPromising antibody may prove useful against deadly Ebola virus outbreaks
New research reveals the workings of a human antibody called mAb 3A6, which may prove to be an important component for Ebola virus therapeutics.

NewsPromising new class of antimalarial drugs discovered
A new study identifies an inhibitor of gene regulation that specifically kills the malaria pathogen. The chromatin remodeler PfSnf2L is a key regulator of genes that play an important role in various stages of the pathogen’s development.
