NewsBacteria found thousands of metres high in the sky
Researchers have discovered the widespread presence of prokaryotic and eukaryotic eDNA in the atmosphere, including pathogenic bacteria and bacteria previously unknown to be present in the atmosphere but found in other extreme environments such as deep-sea sediment.
-
NewsClinical trial of mRNA universal influenza vaccine candidate begins
A clinical trial of an experimental universal influenza vaccine, H1ssF-3928 mRNA-LNP, has begun enrolling volunteers to test for safety and its ability to induce an immune response.

NewsWild bees in the city show more pathogens and inbreeding
Changes to the microbiome are seen in wild bees living in densely urban areas and fragmented habitats, which makes it more difficult for the bees to access food sources, ideal nesting areas and mates.
-
NewsWarning over lack of ‘substantial evidence’ for FDA approved antibiotic
Drugs approved in the US require “substantial evidence” that they are effective, but an investigation by The BMJ into the recent approval of the antibiotic Recarbrio from Merck suggests that these standards are being bypassed.
-
NewsHeat-loving marine bacteria can help detoxify asbestos
Researchers have shown that extremophilic bacteria from high temperature marine environments can be used to reduce the toxicity of asbestos.
-
NewsTracking AMR in E. coli isolated from swine reveals worrying trends
Scientists have carried out the first surveillance study in the US that looks at antimicrobial resistance in E. coli from swine at slaughter.
-
NewsResearchers use 3D models to investigate movement of Helicobacter pylori
Scientists have created a 3D model of Helicobacter pylori to better understand its movement, hoping to crack the code governing the organism’s motility and develop alternative treatments for infections, such as strengthening the gastric mucus barrier that stands against the bacteria.
-
NewsEndophytes colonize and protect coffee seedlings
Fungi found living within the tissue of plants from old growth forests in Costa Rica can colonize coffee seedlings and protect them from disease, a new study has revealed.
-
NewsTraditional medicine plant could combat drug-resistant malaria
Researchers have identified compounds in the leaves of a particular medicinal Labrador tea plant used throughout the First Nations of Nunavik, Canada, and demonstrated that one of them has activity against the parasite responsible for malaria.
-
NewsSecond gene implicated in malaria chloroquine resistance evolution
How malaria parasites evolved to evade a major antimalarial drug has long been thought to involve only one key gene. Now, scientists have shown a second key gene is also involved in malaria’s resistance to the drug chloroquine.
-
NewsProchlorococcus ancestors rafted out to sea on chitin particles
Scientists propose that ancestors of Prochlorococcus hitched a ride on passing exoskeleton particles, using the particles as rafts to venture further out to sea. These chitin rafts may have also provided essential nutrients, fueling and sustaining the microbes along their journey.
-
NewsPostal HPV kits boost cervical screening uptake
At-home high-risk human papillomavirus (hrHPV) sampling kits can help increase cervical cancer screening among under-screened women from low-income backgrounds, according to findings from a US-based clinical trial.
-
NewsInter-species interactions may stymie antibiotics
A new study suggests that between-species interactions within the gut microbiome may impact the efficacy of antibiotics aimed at treating C. difficile infections.
-
NewsEye drops cause infection long before CDC warning
A patient was diagnosed with a dangerous Pseudomonas aeruginosa eye infection caused by contaminated eye drops, months before the CDC issued warnings against using the product.
-
NewsScientists ID microbes that associate with oilcane
Researchers have identified the types of microbes that associate with engineered oilcane, opening the way to new opportunities to leverage plant-microbial interactions in these feedstocks, which could increase oil yields for sustainable bioenergy production.
-
NewsLaser breathalyzer sniffs out COVID in real time
Scientists have made an important leap forward in the quest to diagnose disease using exhaled breath, reporting that a new laser-based breathalyzer powered by artificial intelligence (AI) can detect COVID-19 in real-time with excellent accuracy.
-
NewsYeast evolves into multicellular life in the lab
A fascinating long-term evolution experiment has seen model organism ’snowflake yeast’ adapt into multicellular individuals more than 20,000 times larger than their ancestor.
-
NewsMeet Ginger: the gene-edited calf resistant to BVDV
Scientists introduce Ginger, the first gene-edited calf with reduced susceptibility to a major viral pathogen.
-
NewsCRISPR-based drug candidate targets the microbiome
Scientists have engineered the first published CRISPR-based candidate for a drug - a combination of phages - that targets E. coli directly and leaves the microbiome intact.
-
NewsPattern-forming bacteria used with AI as sensors
Synthetic biologists have engineered bacterial swarm patterns to visibly record environment and use deep learning to decode patterns - applications could range from monitoring environmental pollution to building living materials.
