NewsEbola virus hides in the central nervous system, according to new research
Ebola virus can survive unnoticed in the human body for months or even years, hiding in areas with little immune surveillance like the central nervous system. Using a cerebral organoid model, researchers have gained valuable insights into the mechanisms of Ebola virus persistence.

NewsAI unlocks the secrets of viruses: Birth of large protein structures for vaccine delivery
An international research team has succeeded in designing large-scale protein structures that faithfully replicate the self-assembly principles found in naturally occurring viruses, using artificial intelligence (AI).

NewsA new HIV vaccine study reveals new hope—and new challenges—for aging patients
A new clinical trial demonstrates that novel vaccines can significantly boost T cells targeting and could contribute to curative approaches against HIV.

NewsRNA barcoding approach reveals previously unknown virus-host relationships
Researchers have uncovered previously unknown relationships between bacteriophages and their bacterial hosts. They found a previously unreported group of bacterial hosts for the well-studied bacteriophage P1 and examine how subtle changes in viral structure influence which microbes a phage can target.

NewsResearcher secures nearly $4 million NIH grant to advance therapeutic vaccine to help end genital herpes
University of California, Irvine immunologist Lbachir BenMohamed has been awarded a $3.93 million National Institutes of Health grant to develop and test a novel therapeutic vaccine designed to prevent recurrent genital herpes.

NewsTherapeutic vaccine shows mixed efficacy in preventing head and neck cancer recurrence
Researchers explore the effectivity of new therapeutic cancer vaccine in preventing the recurence of human papillomavirus triggered cancers.

NewsSingle amino acid change may help viruses jump from bat to human
New research reports that a single amino-acid change alters how a coronavirus protein interacts with the human and bat immune systems, shifting the body’s response to infection.

NewsHow specific humidity affects flu outbreaks - and what it means under climate change
In temperate regions, flu season is in the winter, while in the tropics, constant low-intensity activity is typically punctuated by two annual peaks—or a surge during the rainy season. Researchers investigated whether specific humidity—the mass of water vapor per unit mass of air—could explain these differing patterns.

NewsJust 10 viral particles can cause H5N1 avian flu infection in cows
Just 10 viral particles of the H5N1 bird flu that caused hundreds of influenza outbreaks in U.S. dairy cattle can cause infection in cows, a new study shows. The research also hints at why the outbreaks have confounded scientists, farmers and livestock handlers hoping to contain and prevent the disease.

NewsPlant viruses open new routes for gene editing
A new study has developed potyvirus-derived vectors for delivering CRISPR RNA (crRNA) guides in Lachnospiraceae bacterium ND2006 Cas12a (LbCas12a)-expressing plants, expanding virus-induced gene editing from tobacco rattle virus (TRV) to tobacco etch virus (TEV), turnip mosaic virus (TuMV), and lettuce mosaic virus (LMV).

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.

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.

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.

NewsElsevier launches Ebola Information Center with free clinical and research resources
Elsevier has launched an Ebola Information Center to provide healthcare professionals, researchers, policy makers and the public with free access to critical clinical and research information to support the global response to this outbreak.
-
NewsMolecular anchors on gut phages may open new avenues for therapeutic development
A new study has identified phage surface proteins acting as molecular anchors. These proteins confer phages with the ability to attach to human cells. Using genetic engineering, the researchers transferred these adhesion proteins onto the surface of another phage that otherwise lacked this ability.

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.

NewsGenomic analysis redefines the origin of eukaryotic cells
A new genetics study using the MareNostrum supercomputer redefines the genetic origin of the last common ancestor of all eukaryotes, highlighting the contribution of novel bacteria and even giant viruses in the emergence of eukaryotic cells.

NewsAsk the expert: World Cup travel and Ebola risk
Luis Ostrosky, MD, division chief of infectious diseases at McGovern Medical School at UTHealth Houston and chief epidemiology officer for Memorial Hermann Health System addresses the Ebola outbreak in Congo and Uganda and how the United States could be affected through travel.
