Using biotechnology, scientists have genetically modified goats to produce milk containing chemicals that protect against deadly nerve agents such as sarin and VX.
Goats make milk to protect from nerve gas.
If the work is successful the drug could be used to protect troops against exposure to nerve agents on battlefields, or stockpiled for use in the event of a chemical weapon attack on a city.
The drug will still have to go through safety trials and gain US government approval.
