Plain English
African swine fever virus uses a protein called pC147L to shut down a key antiviral warning system in pig cells without touching other immune defenses. The protein physically blocks the assembly of a signaling complex that would otherwise trigger interferon production, allowing the virus to replicate more freely in pig lung immune cells. Identifying this mechanism reveals pC147L as a potential target for developing vaccines or antiviral strategies against this devastating livestock disease.

Plain English
Two antiviral drugs used to treat chronic hepatitis B — tenofovir alafenamide (TAF) and tenofovir disoproxil fumarate (TDF) — were compared for their ability to prevent liver cancer in 1,364 previously untreated patients followed for five years. Patients taking TAF developed liver cancer at roughly one-third the rate of those on TDF, an approximately 71% reduction in risk after statistical adjustment. While the study's observational design and small number of cancer events require cautious interpretation, the findings support larger studies to confirm whether TAF offers a meaningful cancer prevention advantage.

Plain English
Researchers analyzed gene expression data from liver cancer tumors treated with sorafenib — a standard drug for advanced liver cancer — and developed a 50-gene signature called KUSS50 to predict which patients would benefit from the drug. When validated in two independent clinical trial datasets, KUSS50 identified sorafenib-responsive tumors with over 87–90% specificity.
