Study Identifies Genetic Regulators Hijacked By Avian And Swine Flu Viruses
Researchers at the University of British Columbia have identified a number of tiny but powerful "genetic regulators" that are hijacked by avian and swine flu viruses during human infection. The discovery, published in the Journal of Virology, could reveal new targets for broad-spectrum antivirals to combat current - and perhaps future - strains of influenza A viruses...
New UK Abortion Statistics: 12 Women A Day Travel From Ireland To Britain To Access Abortion Services
