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 ...

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 ...

Wheeler said that if a cow produced one gram of insulin per liter of milk and a typical Holstein cow – which produces more milk than any other breed of dairy cow – made 40 to 50 liters a day ...

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 ...

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.

"The less human or cow transmission we have, the fewer of these mutations the virus can acquire." 2. Human-to-human spread of bird flu remains extremely rare It's generally rare for people to ...

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 ...

The case was confirmed in a dairy worker in Colorado. The fourth human case of bird flu linked to the current dairy cow outbreak was confirmed on Wednesday in a dairy worker in Colorado ...
