NewsLignin is effective against viruses and bacteria
Lignin, a polyphenol, has antimicrobial activity against viruses and bacteria. An by-product from wood industry, lignin has potential as promising green alternative to synthetic antimicrobial agents for coating agents, packaging material, or surface disinfectants.

NewsAs school returns, so do infections & asthma emergencies. Where kids live can make it worse
A new study highlights how neighborhood conditions shape the seasonal surge of virus-triggered asthma emergencies. It found that children in under-resourced communities face sharply higher rates of asthma flare-ups tied to viral infections during the first weeks of school.

NewsFast, accurate, low-cost diagnostics - and no lab required
Researchers have developed a breakthrough diagnostic tool that could transform how quickly and reliably we detect illnesses like COVID-19, Ebola, AIDS or Lyme disease. The test uses just a single drop of blood, costs a couple of dollars and delivers results in only 15 minutes.

NewsScientists trace the evolution of the H5N1 virus
Researchers have discovered that the currently circulating 2.3.4.4b clade of H5N1 has specific mutations in its genome that increase its human adaptive potential.

NewsStudy: Long COVID remains a substantial financial and medical burden
Individuals with long COVID-19 experienced worse financial and employment outcomes – lasting up to three years after their initial infection. Notably, vaccination against COVID-19 was associated with strikingly improved work and financial outcomes.

NewsGlobal Virus Network reaffirms support for mRNA vaccines and collaborative vaccine research
The Global Virus Network (GVN) has announced that it is unequivocally committed to the continued development and deployment of mRNA vaccines and the global scientific collaboration that makes such innovation possible.

NewsEarly challenges to the immune system disrupt oral health
Researchers identified changes over time in the oral microbiome of children living with HIV, offering insights into how early immune challenges shape not only oral health but also systemic health.
-
NewsScientists develop new approach to fighting many viruses at once
Scientists have developed a research pipeline to fuel the development of “universal vaccines,” that would address broad viral families and mutated viral variants.

NewsNovel immunologic surveillance study provides new insights into post-pandemic return of respiratory viruses
Non-pharmaceutical interventions such as masking and distancing targeted towards SARS-CoV-2 during the pandemic also decreased circulation rates of and population immunity to common respiratory pathogens in children, a new study shows.

NewsNew European toolkit launched by EU agencies to help eliminate viral hepatitis B and C in prisons
The European Union Drugs Agency (EUDA) and the European Centre for Disease Prevention and Control (ECDC) have jointly produced a European toolkit for the elimination of viral hepatitis in prisons.

NewsRNA immunity: A silent defender against viruses in mammals
Researchers propose that small RNA molecules play a direct and specific role in fighting viral infections in mammals. RNA immunity relies on the base-pairing precision of small RNA fragments, such as microRNAs, to recognize and suppress viral genetic material.

NewsSweet disguise: the human body hides RNA with sugar coatings
To our immune system, naked RNA is a sign of a viral or bacterial invasion and must be attacked. But our own cells also have RNA. To ward off trouble, our cells clothe their RNA in sugars, a new study reports.

NewsNew drug combo outperforms Tamiflu in fighting flu (and chocolate is the key)
Scientists have unveiled a new drug pairing - including a compound found in chocolate - that outperforms Tamiflu, the most widely used anti-influenza medication, against even the deadliest flu strains, including avian and swine flu.

NewsStudy finds gaps in evidence for air cleaning technologies designed to prevent respiratory infections
A new study finds that although many technologies claim to clean indoor air and prevent the spread of viruses like COVID-19 and the flu, most have not been tested on people and their potential risks are not yet fully understood.
-
NewsResearchers debunk long-standing concern about flu treatment in children
Researchers have debunked a long-standing theory about oseltamivir, known as Tamiflu. Oseltamivir treatment during flu episodes was associated with a reduced risk of serious neuropsychiatric events, such as seizures, altered mental status and hallucination.
-
NewsWhy killer cells can lapse into ‘exhausted’ CD8+ T cells that no longer can stem disease
In a detailed study of exhausted T cell subsets researchers show that a transcriptional repressor called Gfi1 is a key regulator of the subset formation of exhausted CD8+ T cells and may offer a key to reducing exhaustion.

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.
