NewsDo imported cut flowers spread livestock viruses?
A study investigated whether Culicoides biting midges are being accidentally exported from Africa to Europe in shipments of cut flowers. Although researchers did detect small numbers of these insects near and inside greenhouses on a Kenyan flower farm, they found none in packaging or transport areas.

NewsNew study reveals where HIV hides in different parts of the body
A new study reveals that HIV cloaks itself in the DNA of infected cells using unique DNA patterns in the brain, blood and parts of the digestive tract. For example, in the brain, the virus avoids genes and hides in less active parts of the DNA.

NewsAntibody discovered that blocks almost all known HIV variants in neutralization assays
An international research team has discovered an antibody that could advance the fight against HIV. The newly identified antibody 04_A06 proved to be particularly effective in laboratory tests. It was able to neutralize 98.5 percent of more than 300 different HIV strains, making it one of the broadest antibodies against HIV identified.

NewsResearch reveals fetuses exposed to Zika virus have long-term immune challenges
Researchers discovered that when a pregnant mother is infected with Zika virus, the resulting inflammatory response in the placenta permanently changes how the offspring’s immune system develops - even if the infection is mild or asymptomatic in the mother.

NewsLong Ebola: Sudan virus can persist in survivors for months, study shows
More than half of survivors of the Sudan Ebola virus still suffer serious health problems two years post-infection and the virus can persist in semen and breast milk for months after recovery, according to the first study examining the virus’s long-term effects.

NewsScientists explore how viruses replicate and infect
Herpes viruses cultivated using one kind of host cell – known as a producer cell – exhibited differences from the same virus cultivated with a different producer cell.

NewsResearchers deconstruct chikungunya outbreaks to improve prediction and vaccine development
Researchers analyzed more than 80 outbreaks of chikungunya virus to improve prediction of future outbreaks and inform vaccine trial development.

NewsThe RESTART trial: a drug to block a toxic HIV molecule
What if the presence of a well-known but misunderstood viral protein explains why some people living with HIV (PLWH) never recover their health, even with antiretroviral treatment? Researchers will explore this in a groundbreaking clinical trial this fall.

NewsAI can be valuable tool to strengthen pandemic preparedness
Artificial intelligence could be a valuable tool for detecting emerging diseases earlier, researchers from five European universities and research institutes argue.

NewsSome human GII.4 norovirus are better than others at infecting cells; researchers have found out why
A study reveals that human GII.4 noroviruses have evolved a uniquely potent entry mechanism with clear strain-specific differences. The findings open new possibilities for identifying the elusive human norovirus receptor as well as developing vaccines and treatments.

NewsHeart rhythm disorder POTS common in patients with long COVID
A new study shows that an unusual heart rhythm disorder, POTS, is particularly common in people with long COVID. The majority of those affected are middle-aged women.

NewsBreakthrough results from elephant herpesvirus trial find vaccine to be safe
The world’s first vaccine trial against elephant endotheliotropic herpesvirus (EEHV) – a leading cause of death in young Asian elephants – is safe and triggers a strong virus-fighting immune response, according to a research team.

NewsNew antibiotic targets IBD — and AI predicted how it would work before scientists could prove it
The new antibiotic, enterololin, attacks and kills only a specific group of disease-causing bugs, which includes the type of E. coli that drives Crohn’s disease. It is a promising new treatment option for people affected by Crohn’s and other IBD-related conditions.

NewsGenetic ‘Trojan horse’ selectively kills cancer cells linked to Kaposi’s sarcoma
A highly targeted gene therapy that could revolutionize treatment for cancers linked to a common herpesvirus harnesses an adeno-associated virus (AAV) to deliver a genetic “Trojan horse” into infected cells.

NewsQdenga vaccine shows effectiveness against dengue under real-world conditions during Brazil’s 2024 outbreak
An international team of researchers has demonstrated that the tetravalent dengue vaccine Qdenga provides significant protection against the disease under real-world conditions, during the large 2024 epidemic in São Paulo, Brazil.

NewsNew insights into how pathogens build protein machinery for survival in the gut
New research reveals how pathogenic bacteria construct tiny protein-based compartments, known as Eut microcompartments, which enable them to digest ethanolamine - a nutrient commonly found in the gut.

NewsIndia could bear biggest impact from chikungunya, new maps suggest
Based on existing evidence of chikungunya transmission, an infectious disease model predicts 14.4 million people could be at risk of infections globally each year, with 5.1 million people at risk in India.

NewsScientists uncover molecular mechanisms for bacterial lipid transport
Researchers have successfully applied cryo-electron microscopy (cryo-EM) to unveil the molecular structures of critical protein machines that transport lipids and maintain the outer membrane (OM) barrier of Gram-negative bacteria.
-
NewsPotential biomarker for the development of long COVID identified
A research team has demonstrated that a specific component of the immune system (PTX-3) remains at significantly higher levels in the blood of patients who have suffered from severe COVID-19, even months after the acute infection has subsided.

NewsPeptide study paves path toward new weapon against antibiotic-resistant bacteria
New research into antimicrobial peptides, small chains of amino acids able to damage bacterial cells, shows why some peptides are more effective at doing that and also why some cells are more vulnerable.
