NewsStudy shows how pre-existing immunity shapes second dengue infections
Why can a second dengue infection be more dangerous than the first? A controlled human challenge study shows how pre-existing antibodies can either boost viral replication or help restrain it, offering new clues for designing vaccines that protect against all four dengue virus types.

NewsGene-regulatory pathway helps T cells tolerate gut bacteria and prevent inflammation
The immune system somehow tolerates trillions of gut bacteria without constantly attacking them. Researchers have now identified a gene-regulatory pathway that helps regulatory T cells maintain this peace, with defects in the pathway triggering severe inflammation and autoimmunity in mice.

News$16.4m NIH grant launches new hepatitis C vaccine centre
Hepatitis C has long frustrated vaccine developers with its extraordinary ability to mutate and evade immunity. A new $16.4 million research centre will bring together experts in antibodies, T cells and vaccine design to identify the virus’s most stable weak points and develop broadly protective vaccine candidates.

NewsAvian flu could push vulnerable vulture populations into further decline
H5N1 avian influenza is emerging as a serious threat to already vulnerable vulture populations, with deaths reported across the Americas and Europe. Researchers warn that losing these scavengers could also weaken a natural barrier against disease by allowing infected carcasses and pathogens to persist for longer.

NewsDistant climate patterns may offer early warning of Ebola outbreaks
Ebola outbreaks may leave a climatic trail months before they emerge. By analysing nearly five decades of outbreak data alongside large-scale climate oscillations, researchers identified distant weather patterns that could help flag periods and regions where Ebola risk may be increasing.

NewsAncient virus may have helped shape differences between human and chimpanzee brains
A virus that infected chimpanzees millions of years ago may have left a lasting mark on brain development. Researchers found that a viral DNA remnant silences a gene involved in early brain development in chimpanzees, while the same gene remains active in humans.

NewsTwo-in-one tool tracks viral RNA inside live infected cells in real time
The tool lets researchers film activity of Zika and chikungunya viruses in high resolution and identify virus-host interactions, a key step to developing effective antiviral strategies that could stop infections

NewsMigratory birds spread avian influenza to Greenland’s polar bears
Migrating birds that breed in the Arctic are spreading avian influenza to polar bears in eastern Greenland, according to a new study that found evidence of infections in bear blood samples acquired from Greenland Inuit subsistence hunters.

NewsScientists reveal how deadly Andes hantavirus attaches to human cells
Earlier this year, an outbreak of Andes hantavirus on a cruise ship, which killed three passengers and sickened 13, highlighted the lack of approved vaccines or treatments for the virus. Scientists now show how the virus recognizes its target on a human cell, a finding that could lead to effective therapies against Andes virus and other hantaviruses.

NewsChildhood measles vaccination rates fall worldwide post COVID-19
Routine vaccine program disruptions and under-resourced health systems are driving a global decline in childhood measles vaccination rates post COVID-19, a study has found.

NewsBelgium’s top science foundation honors 'Virus Hunter'
’Virus Hunter’ Ken Stedman has been named an International Collen-Francqui Professor for the 2026-27 academic year, an honor the Francqui Foundation reserves for scientists it considers among the best in their field.

NewsScientists create white blood cell with memory of how to fight off winter flu bugs
Scientists have started work on a new way to fight cold and flu viruses by reprogramming the cells in our immune system to respond faster to infections. They are developing a type of white blood cell, called killer cells, with a pre-installed memory of how to fight off respiratory diseases.

News‘Raman barcodes’ can distinguish 20 SARS-CoV-2 variants
Viruses may carry a molecular ‘barcode’ hidden not just in their genetic sequence, but in the way their RNA folds and vibrates. Researchers have used Raman spectroscopy to distinguish 20 SARS-CoV-2 variants and subvariants, pointing towards a potentially faster way to screen emerging viral strains.

NewsScientists ‘crank up’ cells’ natural defence against viruses
Researchers have found a way to amplify one of the body’s natural antiviral defence pathways, making cells significantly more resistant to infection. By boosting signalling through the protein ISG15, the approach could lead to host-directed treatments that remain effective even as viruses mutate.

NewsU-M-led consortium to receive up to $52 million in NIH funding to study why viral respiratory infections affect children differently
A Michigan Medicine-led research consortium has secured approval for up to $52 million in federal funding to launch a multicenter study examining why some young children recover fully from viral lower respiratory tract infections while others develop severe illness or lasting problems such as asthma.

NewsCommon cold sore virus may reprogram the brain’s immune defenses
Researchers have discovered how herpes simplex virus type 1 (HSV-1), the virus that causes cold sores, can fundamentally change how the brain’s immune cells respond to infection, revealing a potentially important connection between viral infection, chronic inflammation and Alzheimer’s Disease.

NewsStudy uses artificial intelligence to design potential antiviral compounds
Researchers have developed an artificial intelligence (AI)-guided strategy to discover molecules that inhibit deoxyhypusine synthase (DHPS), a human enzyme involved in eIF5A hypusination, a process that supports the replication of a broad range of viruses. The researchers experimentally tested AI-generated molecules.

NewsSkin injection of live flu virus provides durable protection without lung damage
A single subcutaneous injection of a live, unattenuated influenza virus can provide durable protection against lethal flu without causing lung damage, according to new findings that challenge the long-standing trade-off between the safety of inactivated vaccines and the potent immunity of live vaccines.

NewsVirus-based tool opens a faster route to studying cowpea genes
Genome sequencing of cowpea has provided researchers with numerous candidate genes, and genetic transformation has enabled studies of traits such as drought and heat tolerance. A new study reports sustained gene silencing across seven cowpea varieties and demonstrates the system’s utility for investigating jasmonate regulation during leafminer infestation.

NewsNew platform reveals broad viral exposure histories in pigs
Pigs can retain antibody traces of past viral encounters, yet conventional tests usually examine only a limited number of viruses at a time. Researchers have developed a platform that uses 36,416 short protein fragments from 140 swine-associated viruses to screen many antibody responses in parallel.
