Crack the vast menu at any self-respecting beer bar, and you're bound to run into a scientific name among the descriptions: Brettanomyces, affectionately known as Brett.
I've heard American brewers and beer geeks utter "Brett" in hushed, reverent tones before swooshing aromatic liquids made with it across their tongues. But this mysterious, mythic and increasingly popular strain of wild yeast also strikes fear in the hearts of brewers and microbiologists in the industry.

In today's world it can be easy to feel like there's nothing left to discover, that all the blank bits of the map have long been filled. Gregory Asner begs to differ, and he's developed a lab in the sky to prove it.
In the Carnegie Airborne Observatory, Asner has designed a one-of-a-kind, ultra high-tech, airborne laboratory — inside a twin-turboprop plane. It offers a faster, more exhaustive way to map how humans have destroyed land, from the deserts of the American southwest to the deepest depth of the Amazon.
Comet 67P/Churyumov–Gerasimenko, the hurtling hunk of dust and ice that's being tailed by an Earth-made space probe as it hurtles toward the sun,

Like it or not, our seafood increasingly originates not in the deep ocean but on fish farms hugging the coasts. Aquaculture already supplies about half of the world's seafood, and global production is going to have to more than double by 2050 to meet demand, according to the World Resources Institute.
The business opportunity here is tremendous. Thousands of operations around the world now produce huge numbers of salmon, shrimp, mussels, tilapia and catfish, to name a few fish species that thrive on farms.
