Episode notes

Even at 20 % substitution, there were huge gains to be made. There are some caviats though, unlike cows, these bi reactors where microbial protein is produced use a lot of electricity. And this wasn't accounted for in florien's model. But it also points to another very important transformation an its the transformation of energy systems. If electricity generation be largely carbon neutral or carbon free, then, of coffes would also reduce the environmental impact of energy used for any sort of seled agriculture.

00:46 How a move to microbial protein could affect emissions

It’s well understood that the production of meat has large impacts on the environment. This week, a team show that replacing 20% of future meat consumption with protein derived from microbes could reduce associated emissions and halve deforestation rates.

10:47 The neurons that help mosquitoes distinguish smell

Female Aedes aegypti mosquitoes strongly prefer human odours to those of animals, but how they distinguish between them is not well understood. Now, researchers have shown that human odours strongly activate a specific area in the brains of these insects, a finding that could have important implications for mosquito-control strategies.

18:05 Briefing Chat

We discuss some highlights from the Nature Briefing. This time, how climate change could affect virus transmission between mammals, and how the link between a dog's breed and its temperament may not be as close as previously thought.
