NewsResearchers uncover how obesity impairs vaccine response
New findings reveal that obesity significantly impaired the quality and longevity of antibody responses to a Pseudomonas aeruginosa vaccine in a mouse model. The impaired antibody production was due to defects in germinal centers.

NewsShorter antibiotic courses show similar outcomes to longer use for some pneumonia patients
A multicenter target trial emulation found that for eligible patients hospitalized with community-acquired pneumonia (CAP), health outcomes were similar whether they received a three- to four-day course of antibiotics or a course lasting five days or more.

NewsNew biodegradable wash removes pesticides and extends produce shelf life
Researchers have developed a natural, biodegradable wash that removed up to 96 per cent of pesticide residue from fruit and slowed browning and moisture loss.

NewsTwo research projects to study immune responses to dengue and Zika viruses
Dr. James Earnest, an assistant professor at the Burnett School of Biomedical Sciences, is leading two new research projects to examine how humans build an immune response to dengue and the Zika virus over time, in pursuit of creating better preventative measures.

NewsWildlife trade increases pathogen transmission
A study combining forty years of legal and illegal wildlife import-export data with compilations of host–pathogen relationships found that wild mammals that are traded are 1.5 times more likely to share infectious agents with humans than those that are not involved in trade.

NewsResearchers explore potential link between COVID-19 and lung cancer risk
New findings have identified a potential association between COVID-19 and increased lung cancer risk, driven by underlying biological mechanisms in the lung. The study integrates human clinical data with mechanistic research in animal and cellular models.

NewsNanodisc platform improves vaccine design for Ebola, HIV and more
Scientists have created a platform that allows viral surface proteins to be studied in a form that more closely resembles how they appear naturally, utilizing nanodisc technology where these proteins are embedded into particles made of lipid molecules, preserving them in a membrane-like structure.

NewsNon-producing oil and gas wells emit microbial methane at rates 1,000 times higher than previously estimated
Microbial methane leaking from non-producing oil and gas wells is being emitted at rates about 1,000 times higher than previously estimated, according to a new study.

NewsHidden ocean feedback loop could accelerate climate change
Scientists have uncovered a key mechanism behind methane production in the open ocean. Their research indicates that this mechanism could intensify as the planet warms, providing an alarming feedback loop for global warming.

NewsTropical trees are more neighborly, study suggests
Tropical trees are better neighbors than trees in temperate forests, according to a new study. Trees growing closer to the equator have more positive interactions with their neighbors, which may help explain why tropical forests are home to so many tree species.

NewsA smarter way to build vaccines: scientists harness AI to target emerging alphaviruses
Scientists have developed a new computational pipeline that could dramatically accelerate the development of vaccines against a group of mosquito-borne viruses known as alphavirus.

NewsPhase I study for human monoclonal antibody for Lyme disease demonstrates safety, tolerability, pharmacokinetics
A Phase I clinical trial of a human monoclonal antibody discovered and developed for the prevention of Lyme disease in the U.S. was well tolerated and showed lasting serum concentrations in participants, according to data.

NewsResearchers to test a gut microbiome intervention as part of a cancer therapy regimen
A phase III clinical trial will test a gut microbiome intervention as part of a kidney cancer therapy regimen. The investigational agent is a once-daily capsule requiring no refrigeration or special handling.

OpinionWhy chromogenic media matters when testing for invasive pathogens: Could the cheapest plate be an expensive decision?
Chris Armstrong, President of Microbiology, Thermo Fisher Scientific, argues that laboratories should stop judging fungal culture media on unit price alone.

NewsBird flu spread could be impacted by where waterfowl like to live
The movement patterns of waterfowl, including ducks, swans and geese, may affect the spread of highly pathogenic avian influenza in bird populations. Researchers found that birds travel much shorter distances in areas with human activity.
-
NewsResearchers develop new solar-powered water disinfection system
Researchers have developed a new solar-powered water disinfection system that combines several existing methods. The compact device effectively utilizes a combination of techniques that all use solar energy.

NewsUnlocking how dogs’ fungal ear infections evade treatment points vets to drug stewardship
Mutations in a key protein make a yeast found in dogs with common outer ear infections more resistant to the topical antifungals used to treat it, veterinarians and pathobiologists found in a new study.

NewsTurmeric/ginger extract shows multiple benefits for bone implants
An extract of turmeric and ginger helps bone implants bond strongly while killing bacteria and cancer cells, according to new research with implications for millions of patients with joint replacements and bone cancer.

NewsHIV infections would increase by 10% average if CDC funding for HIV testing ends, study predicts
Researchers used a computer model to quantify the effect of funding cuts for HIV testing. They estimate that HIV infections could increase an average of 10% in 18 U.S. states if this funding is interrupted or ended.

NewsBacteria incorporate forever chemicals into cell membrane molecules
New research shows that bacteria incorporate polyfluoroalkyl carboxylates—a type of Per- and Polyfluoroalkyl Substances (PFASs)—into the molecules that make up their cell membranes.
