  • I’m glad it was interesting! I think we’ll all appreciate more variety in our diets.

    The apples you mentioned are a good example of this. Apple breeders used to always breed the flavour away in favour of looks since that’s what sells. When one guy bred a tasty apple, only for his colleagues to make it tasteless again, he decided to brand it and enforce some quality control. Breeders were very skeptical, and few could imagine that consumers would care about what apple variety they’re eating - do you know what type of potato or cucumber you buy? But in the end, consumers proved willing to engage and branded apples are now widespread. Tenderstem broccoli has recently inspired Brassica breeders to start branding and marketing their new varieties.

    I’m involved with some breeders trying to do the same with potatoes!


  • Not quite, but close! Molecular plant breeder here.

    There is no set “limit” to flavour but it’s a complex trait that is easy to lose if you don’t select for it. If you breed for size, and don’t track taste, it’s very easy to leave the flavour-producing aspects unchanged, thus resulting in a “dilution”. Furthermore, you’re often actively selecting against flavour, indirectly and unintentionally, by selecting for shelf life - if something doesn’t ripen, it won’t over-ripen and spoil.

    This is what has historically happened to a lot of produce but it doesn’t have to be the case - modern breeding lets us breed for flavour and nutrition too! Heirloom varieties can offer some reprieve, but for all their taste they tend to be quite unproductive and sickly (ofter “heirloom” means inbred and that does not produce very fit organisms).

    Good news is, new varieties are being bred that have it all - yield, taste, and nutrition! It’s just hard to convince consumers and businesses to switch over to new varieties, as you don’t really buy according to the flavour, just the looks.

    Greetings from the UK ;)




  • Interesting article but it bizarrely completely misses what is likely to be by far the biggest source of climate change-related death: famine. Humans can shelter from the heat and we can displace our air pollution (thanks EVs) but our crops are still stuck in the field and you can pretty accurately predict yield losses from increased temperatures and increased/decreased rainfall.

    This is bad enough in developed nations, where food prices will increase, choice will decrease, and general inequality will worsen. But things will become way worse in developing nations. These mostly practice inefficient, environmentally-damaging subsistence farming and when they start to produce even LESS food, they will just become failed states and hotbeds of civil war. This will bring about much more death and migration, most of it only visible to your average westerner on their TV screen as talk points for your local left/right-wing politicians.


  • I don’t see how these claims are supported by the research in question?

    The main reason is that the article is paywalled (disappointed to see the authors chose to publish in a non-open access journal in 2024) but judging purely by the abstract it seems like this is just a study showing an association between being a black woman in Georgia and signs of stress-induced health issues? Also, they didn’t seem to have a control group?

    The negative effects of chronic stress are well-known but in the linked article this is spun into a weird narrative about microaggressions with seemingly no evidence for it? I am surprised to see the first author of the scientific article deviate so much from the published findings in her journalistic article.







  • I’m not a liar, you just have a very simplistic view of things.

    They knew glyphosate (aka RoundUp) causes cancer and did not disclose it. This likely led to some severe exposure cases and thus they had to pay out (although I strongly believe prison sentences should also have been part of it). This is just as terrible as if I sad sold you lye and never told you it is corrosive, thus endangering you.

    None of this means you cannot use lye for making pretzels/ uncloging your sink. For those uses it is safe. Same for Glyphosate.

    I’d clarify I’m not Bayer fanboy - genetic modification for the sale of a herbicide is a poor use of modern genetic technology. But I cannot deny the measurable climate benefits of using it (in terms of CO2 emissions and soil degradation) source
