NewsWastewater analysis offers a new way to monitor HIV in communities
Human immunodeficiency virus 1 (HIV-1) detection in wastewater offers a novel approach to monitor the virus in communities. Hybrid-capture genetic sequencing allows researchers to analyze viral genomes in detail and specifically identify viral signals coming from community wastewater.

NewsShingles vaccine linked to lower dementia risk in older adults, study suggests
A target trial emulation of older adults entering skilled-nursing facilities found that those who received the recombinant shingles vaccine (RZV) had a lower risk of developing dementia over the following four years compared with those who were not vaccinated.

NewsGlobal map of mycorrhizal fungi reveals true scale of underground networks
Researchers have produced the first global maps visualising the distribution and mass of the Earth’s arbuscular mycorrhizal fungal networks, revealing the true scale of this underground fungal infrastructure.

NewsFermentation science may offer new route to better lower-alcohol wine
In addition to finding ways to ferment grape juice without producing as much alcohol, one scientist is exploring novel yeasts and methods to overproduce aromas to compensate for their eventual loss when reducing alcohol through grape juice dilution.

NewsmRNA flu vaccine offers immune protection against wide array of influenza virus strains
A new study has found that an investigational mRNA influenza vaccine helps the immune system recognize a wider range of influenza viruses than today’s standard flu shot, offering stronger and potentially longer-lasting protection. The vaccine, developed by Moderna, is currently under review by the U.S. Food and Drug Administration.

NewsMetformin given during acute COVID-19 infection reduced risk of clinician-diagnosed long Covid by 50%
New findings from the ACTIV-6 randomized clinical trial provide important confirmation of prior clinical trial results that metformin, a widely available and inexpensive medication with an established safety record, reduced the risk of clinician-diagnosed long COVID when started during acute COVID-19 infection.

NewsGut bacteria linked to osteoporosis risk in primary hyperparathyroidism
Researchers studying primary hyperparathyroidism, a common endocrine disorder characterized by excessive secretion of parathyroid hormone, have identified Bifidobacterium longum as a potential microbial driver of bone loss through immune-mediated mechanisms.

NewsScientists track breakthrough single-dose vaccines for Andes hantavirus strain
Researchers report the development of new vaccines that, in animal testing, provided full protection against the deadly Andes hantavirus after a single dose. They are working to fast-track these single-dose vaccines into human clinical trials.

NewsCapacity of certain unicellular organisms to stick together may be key to animal evolution
Researchers have found that after feeding a specific bacteria to a certain unicellular relative of animals, the single cells began to stick to one another, revealing a possible mode by which our ancestors began to evolve into animals billions of years ago.

NewsResearchers investigate the underlying causes of post-treatment Lyme disease syndrome
With an estimated one million Americans afflicted with post-treatment Lyme disease syndrome, newly funded research seeks to determine whether the condition is triggered by a persistent autoimmune response, and if a test can be devised to pinpoint who is more likely to develop it.

NewsExploring potential of virovory in combating harmful algal blooms
Toxic cyanobacterial blooms can close lakes, contaminate drinking water and pose risks to human health. A new project is exploring an unlikely tool for mitigating these blooms: virovory, the phenomenon of organisms eating viruses as a food source.
