How Now

The cows come home:

Why it matters: Caring about cow farts (or burps) has become a political punchline, but they're estimated to create more than 5% of global greenhouse gasses. Vaccines could be a relatively low-cost, scalable solution, particularly as food demand increases. The science: Methane is much more potent than is carbon dioxide, in terms of its trapping atmospheric heat, although it also dissipates down faster. The deal: Breakthrough Energy Ventures led the Series A round, and was joined by Grantham Foundation, AgriZeroNZ, Rabo Ventures, Overview Capital and The51 Food & AgTech Fund. BEV previously funded ArkeaBio's $12 million seed round.

It's just blowin' in the wind...
