Tens of thousands of hogs are being slaughtered to stop its spread.

The lungs survived with no complications in the animals for up to two months.

Scientists have engineered swine that pollute less, fend off disease, and produce more meat, but you won’t find them outside experimental farms . . . yet.

The organs showed neural activity for up to 36 hours, adding fuel to discussions about the ethics of future neuroscientific research.

The virus caused an outbreak that began in Guangdong Province and left nearly 25,000 piglets dead. 

This 10-centimeter-wide pig eye replica includes even the most intricate of blood vessels, some no wider than 30 micrometers.

The study could pave the way for transplanting porcine organs to humans without the risk of reigniting endogenous retroviruses.

Using the mutagenic chemical N-ethyl-N-nitrosourea, researchers confirm the role of a gene in a piglet deformity and identify potential models for human diseases. 

A donor heart from a genetically modified pig survives for more than 2.5 years inside a baboon’s abdomen.
