A new crop of biotech startups are working on an alternative to alternative protein.
Some of these companies are focused on industrial animal feed, fish meal, and pet food—products with slimmer profit margins but less exacting consumers and fewer regulatory hurdles. Human food, however, is where the real money—and impact—is. That’s why several companies, like Dyson’s Air Protein, are focused on it. In 2023 Air Protein opened its first “air farm” in San Leandro, California, a hub for the commercial food production industry, and announced a strategic development agreement with one of the largest agricultural commodity traders in the world, ADM, to collaborate on research and development and build an even larger, commercial-scale plant. The company’s “Air Chicken” (which, to be clear, is not actual chicken) is slowly making its way toward grocery store shelves and dinner tables. But that’s only the beginning. Other companies are making progress at harnessing bacteria to spin air into protein, too—and someday soon, these microbial protein patties could be as common as veggie burgers.
An alternative to alternative proteins
The environmental case for microbial protein is clear enough; it’s a simple calculus of arable land, energy, and mouths to feed. The global demand for protein is already at an all-time high, and with the population expected to grow to 9.7 billion by 2050, traditional agriculture will have a hard time keeping up, especially as it battles climate change, soil degradation, and disease. A growing global middle class is expected to raise levels of meat consumption, but factory-farmed meat is one of the leading drivers of greenhouse-gas emissions. Although protein-rich alternatives like soy are far more sustainable, most of the soy grown in the world is destined for use as animal feed—not for human consumption.
In contrast, bacterial “crops” convert carbon dioxide directly into protein, in a process that uses much less land and water. Microbial protein “farms” could operate year-round anywhere renewable electricity is cheap—even in places like Chile’s Atacama Desert, where farming is nearly impossible. That would take the strain off agricultural land—and potentially even give us the chance to return it to the wild.
“We are liberating food production from the constraints of agriculture,” Juha-Pekka Pitkänen, cofounder and CTO of the Finnish startup Solar Foods, explained in a recent company video. In April 2024 Solar Foods opened a demonstration factory in Vantaa, a short train ride from the Helsinki airport. It’s here, at Factory 01, that the company hopes to produce enough of its goldenrod-yellow protein powder, Solein, to prove itself viable—some 160 metric tons a year.

Donald Trump’s victory as next president of the United States is depressing news for climate protection. He already made clear that under his presidency
So, in addition to the “silent revolution” of solar and wind energy, strong pressure on governments to change course is still needed. According to the International Monetary Fund (IMF), around seven trillion dollars, or 7,000 billion dollars, are spent each year on direct and indirect state subsidies for fossil fuels – a record amount – which distorts energy markets and prices, offloads damage and costs onto the general public and puts renewables at a massive disadvantage.
Redirecting these funds to clean energy would be an important, fair and socially responsible way to speed up the energy transition.
Vertical solar panels are proving to be a new solution for northern regions, yielding 20 per cent more energy than traditional panels.
The accomplishment “paves the way for long-distance and long-duration missions where creating spare parts, construction components, and tools on demand will be essential.”

Putting this here to refer to. As an old, cis, white guy, I need a refresher once in a while. Especially since I want a diverse cast in my comics.
I’d never write about a person from a different ethnic background. The whole story would probably be full of horrible stereotypes and racist slurs.”Amy closed her mouth, and mine dropped open. Luckily, I was seated when my friend made this statement, but the lawn chair must have sagged visibly with the weight of my disbelief. My own classmate, excluding all other ethnic types from her creative universe!I think this sort of misguided caution is the source of a lot of sf’s monochrome futures. You know the ones I mean, where some nameless and never discussed plague has mysteriously killed off everyone with more than a hint of melanin in their skin. I wonder sometimes what kind of career I’d have if I followed suit with tales of stalwart Space Negroes and an unexplained absence of whites.But of course I don’t. I boldly write about people from other backgrounds, just as many of the field’s best authors do. Suzy McKee Charnas, Bruce Sterling, and Sarah Zettel have all produced wonderful transracial characters, as I show in examples below. Before getting into their work, though, let’s discuss how to prepare for your own.
Radiation damages their DNA; they’re just able to repair that damage very quickly.

A new peer-reviewed study published in ‘Nature Food’ journal found that eating what salmon typically consume — small wild fish such as mackerel, anchovies, and herring — is more nutritionally beneficial to humans.

Source: How birds got their wings
Modern birds capable of flight all have a specialized wing structure called the propatagium without which they could not fly. The evolutionary origin of this structure has remained a mystery, but new research suggests it evolved in nonavian dinosaurs. The finding comes from statistical analyses of arm joints preserved in fossils and helps fill some gaps in knowledge about the origin of bird flight.

This has led researchers to look to dinosaurs to explain some of the features unique to birds, for example, feathers, bone structure and so on. But there’s something special about the wings of birds in particular that piqued the interest of researchers at the University of Tokyo’s Department of Earth and Planetary Science.

Leaving this here in case I need it someday.
The Corsi–Rosenthal Box, also called Corsi–Rosenthal Cube and Comparetto Cube, is a design for a do-it-yourself air purifier that can be built comparatively inexpensively. It was designed during the COVID-19 pandemic, with the goal of reducing the levels of airborne viral particles in indoor settings
Also known as a Corsi-Rosenthal box, this DIY method of building your own air filter with MERV13 furnace filters and a box fan are an easy and cost-effective way to help clear indoor air from airborne virus particles, wildfire smoke, pollen, dust, and more!
If you can seal a box, you can build one (or 100!) of these!
