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.

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.
-
NewsNew-to-nature reaction could decarbonize industry
Researchers have engineered bacteria to produce new-to-nature carbon products that could provide a powerful route to sustainable biochemicals.
-
NewsViruses may disrupt carbon cycle in warming world
Scientists describe many different ways that increasing temperatures could affect viruses and their microbial hosts, changes that could ultimately affect the responses of whole ecosystems to warming.
-
NewsConcerns raised over popular Covid disinfectants
The Covid-19 pandemic has boosted the unnecessary use of antimicrobial chemicals linked to health problems, antimicrobial resistance, and environmental harm, scientists warn.
-
NewsHealthy diet promotes sound gut microbiome
A new study suggests that following the Dietary Guidelines for Americans (DGA) promotes a gut microbiota composition that may support overall health.
-
NewsAntibacterial treatment solves radiotherapy skin problem
A new study shows that a low-cost antibacterial regimen can prevent acute radiation dermatitis.
-
NewsAntibiotics should be halted upon incision closure
New guidelines: antibiotics administered before and during surgery should be discontinued immediately after a patient’s incision is closed, according to updated recommendations for preventing surgical site infections.
-
NewsPreemie infections may come from gut microbiomes
Dangerous bacterial bloodstream infections in premature babies may originate from the infants’ gut microbiomes, according to researchers.
