Will Environmentalists Fall For Faux Fish Made From Plants?

Chef James Corwell's nigiri sushi rolls made with Tomato Sushi, a plant-based tuna alternative, in San Francisco.

It's a dead ringer for Ahi tuna sashimi. It cuts into glistening slivers that are firm and juicy. And it's got a savory bite.

But this flesh-like food is not fish. It's made of tomato, and it's what San Francisco chef James Corwell hopes could be one small step toward saving imperiled species of fish, like bluefin tuna.

"What I want is to create a great sushi experience without the tuna," Corwell tells The Salt.

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.

Taking Antibiotics During Travel Fosters Drug-Resistant Germs

An employee of the drug company Apotex, examines some Ciprofloxacin at the plant in Canada. Cipro is commonly given to travelers for diarrhea. More than 20 million Cipro doses are prescribed each year in the U.S.

Delhi belly. That's what my brother-in-law calls the rumble in his stomach he invariably gets on business trips to India.

Like many travelers, he pops a few Cipro when Dehli belly hits. That may stop the microbes causing the GI distress, but it also opens the door to another unwanted visitor: drug-resisted bacteria.

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.

Goosebumps And Gas: New Data From Rosetta Probe Describes Comet

Close-ups of a curious surface texture on Comet 67P nicknamed "goosebumps," all of them at a scale of around 3 meters and spanning areas more than 100 meters.

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,

We're learning more about the comet that a European Space Agency paired up with its Rosetta probe, thanks to a special issue of the journal Science that collects much of the information scientists have been able to glean from about the comet.

Investment Fund Pours Cash Into Cleaner, Greener Fish Farming

World Resource Institute

Originally published on Thu January 22, 2015 8:21 pm

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.
