Microbiologists have identified the yeast gene that is responsible for the foamy head atop your favorite beer. Now that they know what is responsible for it, they can work with it to create a head that doesn't dissolve too quickly. Cheers to science!

Now that we know exactly which gene is responsible for beer foam, Villa says it's possible to manipulate that gene to create beer with foam that lasts longer — potentially for hours and hours, as our colleagues at Science Friday reported.

He also says the same gene responsible for creating the head on a beer is present in wine as well. His team experimented with these genes and came up with a wine that looks like a beer. "It creates a different kind of wine with a lot of foam," Villa says. "You can play around a little bit."
