Cows have entry portals for both human and bird flus. This new finding may mean that cattle could host both types of flus at once. The two viruses could then swap parts to create a new type of ...

In order to be infected simultaneously with two flu viruses – a bird flu virus and a human flu virus – a cell would need to have both kinds of sialic acid receptors, which cows do, something ...

Bird flu is here to stay. The H5N1 avian influenza is proliferating among U.S. cows and there are now two strains circulating among mammals and birds. Though there are only 68 confirmed cases in ...

Researchers have genetically modified a brown cow in Brazil to produce human insulin in its milk, which marks a breakthrough in diabetes treatment research. The innovative achievement could lead ...

Presley and his colleagues are behind the newly published paper on this one case of cow-to-human bird flu transmission, confirmed in tests carried out in highly biosafe laboratory conditions ...

In Europe and East Africa, several different genetic mutations allowing adults to break down lactose, the sugar present in milk, became some of the most strongly selected traits in the human genome.

Still, human proinsulin and, surprisingly, insulin were detectable in the milk. "Our goal was to make proinsulin, purify it out to insulin, and go from there. But the cow basically processed it ...

As detailed in their paper, the researchers inserted a segment of human DNA coding for the precursor of active insulin called proinsulin into the cell nuclei of ten cow embryos. Out of the ten ...
