NewsBackyard poultry face HPAI risk when migrating mallards stop to rest
Knowing where, when and for how long mallard ducks – natural carriers of avian influenza – stop and rest as they migrate can help predict the probability that they will spread bird flu to backyard poultry flocks, according to a new study.

NewsResearch suggests common viral infection worsens deadly condition among premature babies
Researchers say they found that infection with a common virus that can be transmitted from mother to fetus before birth significantly worsens an often-fatal complication of premature birth called necrotizing enterocolitis (NEC) in experiments with mice.

NewsStudy uncovers porcine reproductive and respiratory syndrome virus’s impact on swine immunity
Scientists used single-cell RNA analysis to reveal key immune mechanisms in lungs of swine infected with PRRSV. They found higher numbers of protective anti-inflammatory M2-like macrophages (SPP1-CXCL14high) were observed in less virulent infections, suggesting a potential role in promoting lung healing.

NewsStealth virus: Zika virus builds tunnels to covertly infect cells of the placenta
Researchers have discovered that Zika virus in the placenta builds underground tunnels, a series of tiny tubes called tunneling nanotubes, that facilitate the transfer of viral particles to neighboring uninfected cells.

NewsPromising antibody may prove useful against deadly Ebola virus outbreaks
New research reveals the workings of a human antibody called mAb 3A6, which may prove to be an important component for Ebola virus therapeutics.

NewsKingdom of Saudi Arabia confirms US $500 million commitment to global polio eradication effort
The Kingdom of Saudi Arabia has reaffirmed its US $500 million pledge to the Global Polio Eradication Initiative (GPEI) in a signing event during the fourth Riyadh International Humanitarian Forum.

NewsScientists warn of increased mpox transmission
International researchers warn that the ongoing mpox outbreak in the Democratic Republic of the Congo (DRC) has the potential to spread across borders more rapidly. The mpox virus has mutated, and the new variant, clade 1b, has become more infectious.

NewsNew therapy may effectively control HIV in Uganda
Clinical trials showed an effective antiviral drug, known as lenacapavir, against HIV in Uganda, and has also been tested for drug resistance in different subtype strains.

NewsNeonatal HSV infections may lead to long-term cognitive impairment
A study has demonstrated that maternal vaccination against herpes simplex virus (HSV) could ameliorate neurological impairment from infected offspring in mice, providing insights for human clinical trials and other neurodegenerative disorders.

NewsDigging into a decades-old hepatitis B mystery suggests a new potential treatment
In their effort to answer a decades-old biological question about how the hepatitis B virus (HBV) is able to establish infection of liver cells, researchers have identified a vulnerability that opens the door to new treatments.

NewsExpedition confirms spread of highly pathogenic avian influenza virus in the Weddell Sea
The CSIC-UNESPA scientific expedition monitoring the presence of the highly pathogenic avian influenza virus (HPAI H5N1) in Antarctica has confirmed the presence of the virus in all species detected on six islands in the Weddell Sea.

NewsTransforming HIV diagnosis: a low-cost, point-of-care detection solution
A team of researchers has developed an innovative handheld device for human immunodeficiency virus (HIV) detection that combines paper-based sample preparation with real-time isothermal amplification.

NewsFungal compound could help protect against influenza
A preclinical trial uncovers how beta-glucan, a compound found in all fungal cell wall, can ‘reprogram’ immune cells to prevent lung inflammation from influenza and lower the risk of death by the host immune responses.

NewsCould microRNAs help us understand why different birds react differently to being infected with bird flu?
Since microRNA was found to have a role in cell protein production, a connection between microRNA and birds infected with bird flu has been found in ruddy turnstones, which has significance with respect to the spread of bird flu due to their long distance flights.

NewsMass polio vaccination campaign to continue in the Gaza Strip
The emergency polio outbreak response in the Gaza Strip is continuing, with a mass vaccination campaign scheduled from 22 to 26 February 2025. The novel oral polio vaccine type 2 (nOPV2) will be administered to over 591,000 children under 10 years of age.

NewsScientists unveil novel anti-CRISPR protein mechanism
Apart from their counter-defensive function, anti-CRISPR proteins hold great promise for enabling more precise control over CRISPR technologies. Researchers have now further elucidated the function of an important yet so far uncharacterized anti-CRISPR protein.

NewsScientists develop new natural killer cell strategy to target HIV
Scientists have successfully identified a new approach using natural killer (NK) cells to target and kill the HIV-positive cells that allow the virus to persist. They genetically modified NK cells to express CD64, a protein not normally expressed by NK cells.

NewsEliminating HIV funding program would lead to >600k deaths in South Africa alone: warning
A new analysis finds that eliminating PEPFAR would lead to 601,000 HIV-related deaths, 565,000 new HIV infections, and would increase population-level healthcare expenditure by $1.7 billion over the next decade in South Africa alone.

NewsEvolutionary tradeoffs: Research explores the role of iron levels in COVID-19 infections
Iron has been found to be essential to both human physiology and pathogen replication. The richer the iron availability, the more likely to be susceptible to infections, such as COVID-19. A balance of iron levels is thus critical for homeostasis and preventing pathogenic infections.

NewsKilling H5N1 in waste milk — an alternative to pasteurization
Researchers have found that acidification can kill H5N1 in waste milk, providing dairy farmers an affordable, easy-to-use alternative to pasteurization of waste milk.
