NewsNew mega RNA virus may hold the key to mass oyster die-offs
Scientists have discovered a previously unknown virus in farmed Pacific oysters during a mass die-off in B.C., Canada. The discovery serves as a reminder that growers should exercise caution when moving young oysters, to prevent potential spread of pathogens.

NewsScientists discover how leukemia virus stays hidden in the body
A research team has discovered how the human T-cell leukemia virus type 1 (HTLV-1) silently persists in the body. Their findings identify a previously unknown genetic “silencer” element that keeps the virus in a dormant, undetectable state.

NewsGene therapy may block HIV transmission during breastfeeding, study shows
Delivering broadly neutralizing antibodies against HIV-1 to newborns via gene therapy provided them with multi-year protection from HIV/AIDS infection, according to an animal study.

NewsStudy highlights the severity of acute necrotizing encephalopathy in kids with the flu
For a small subset of children, influenza can trigger a rare but serious complication called influenza-associated acute necrotizing encephalopathy (ANE). Now, findings of a multicenter study suggest that ANE is often fatal in these children — despite intensive treatment.

News‘One and done’: A single shot at birth may shield children from HIV for years, study finds
A new study shows that delivering a single injection of gene therapy at birth may offer years-long protection against HIV, tapping into a critical window in early life that could reshape the fight against pediatric infections in high-risk regions.

NewsH5N1 found in dairy cattle retains preference for infecting birds, representing low risk to humans
Avian influenza virus from the ongoing outbreak in dairy cattle appears to be keeping its bird-infecting features rather than adapting to better infect other mammals, according to a new study.

NewsMucosal vaccine shows transient action against Covid-19 variant
Mucosal adenovirus vaccine Ad5-XBB.1.5 boosting elicits nasal IgA and transiently prevents JN.1 wave infection for less than 6 months in real-world settings, a new study reveals.

NewsAntiviral treatment fails to slow early-stage Alzheimer’s
A clinical trial has found that a common antiviral for herpes simplex infections, valacyclovir, does not change the course of the disease for patients in the early stages of Alzheimer’s.

NewsPioneering research reveals worldwide scale of Hepatitis C among babies and children
A new study has estimated for the first time the number of children born globally with hepatitis C virus. Each year around 74,000 children globally are born with hepatitis C virus (HCV), with around 23,000 of these estimated to still have HCV infection at age five.

NewsEconomically disadvantaged patients at greater risk for long COVID
A study found that people with social risk factors including economic instability and food insecurity at the time of COVID-19 infection were at greater risk for long COVID.

NewsNew insights could help phages defeat antibiotic resistant bacteria
Researchers have worked out how bacteria defend themselves against viruses called phages and the new insights could be key to tackling antibiotic resistance. The new research is the first to describe how a bacterial defence mechanism against phages, called Kiwa, works.

NewsNew study unlocks molecular defense against devastating potato pathogen
A team of plant scientists has made a significant breakthrough in understanding how potato plants defend themselves against a soilborne pathogen that causes powdery scab, an emerging and economically damaging disease affecting potato crops worldwide.

NewsEngineers take a closer look at how a plant virus primes the immune system to fight cancer
Scientists took a closer look at how the cowpea mosaic virus (CPMV), unlike other plant viruses, is uniquely effective at activating the body’s immune system to recognize and attack cancer cells.

NewsGut microbiome may predict “invisible” chronic fatigue syndrome and long COVID
Millions suffering from myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) may be closer to personalized care, according to new research that shows how the disease disrupts interactions between the microbiome, immune system, and metabolism.

NewsNew AI tool accelerates mRNA-based treatments for viruses, cancers, genetic disorders
A new artificial intelligence model can improve the process of drug and vaccine discovery by predicting how efficiently specific mRNA sequences will produce proteins, both generally and in various cell types.

NewsScientists uncover critical role of membrane protein topology in beta-coronaviruses assembly
Beta-coronaviruses, including SARS-CoV-2, have caused global health problems. How the virus infects host cells and triggers immunological responses has been investigated extensively. However, how the virus replicates and assembles in the cell is largely unknown. Researchers at the Institute of Biophysics, Chinese Academy of Sciences, have uncovered a conserved mechanism ...

NewsTherapeutic vaccine for chronic hepatitis B enters first clinical trial in patients
TherVacB, a novel therapeutic vaccine for chronic hepatitis B, has entered its first clinical trial in patients. A successful phase 1a trial in healthy volunteers saw the vaccine demonstrate a favorable safety profile and trigger the desired immune responses.

NewsHigh-efficacy adjuvanted subunit vaccine against variant infectious bursal disease virus in chicks
Infectious bursal disease (IBD) is an acute, highly contagious disease caused by the infectious bursal disease virus (IBDV), primarily affecting chicks. Notably, the emergence of new mutant strains that exacerbate the disease can cause serious economic losses to the global poultry industry. To date, there is no commercial vaccine against ...

NewsStudy of water bodies frequented by wild birds reveals presence of antimicrobial resistance genes in nine in 10 samples
The first UK study to monitor antimicrobial resistance and influenza viruses in water bodies has revealed that 92% of samples contained genes for resistance to colistin, an antibiotic of last resort.

NewsNew study in Ukraine indicates significant lifetime exposure and ongoing transmission of hepatitis B and C viruses among the general population
A nationwide study in Ukraine has found evidence of significant exposure to hepatitis B and C viruses and substantial ongoing circulation among the population, highlighting need for immunisation and regular screening.
