NewsScientists use blue-green algae as a surrogate mother for ‘meat-like’ proteins
We all know that we ought to eat less meat and cheese and dig into more plant-based foods. But whilst perusing the supermarket cold display and having to choose between animal-based foods and more climate-friendly alternative proteins, our voices of reason don’t always win. And even though flavour has been ...
