Scientists have developed a breakthrough “superfood” for honeybees by engineering yeast to produce the essential nutrients normally found in pollen. In controlled trials, colonies fed this specially designed diet produced up to 15 times more young, showing a dramatic boost in reproduction and overall health. As climate change and modern agriculture reduce the availability of natural pollen, this innovation could offer a practical way to support struggling bee populations.

Using CRISPR-Cas9, scientists engineered a yeast to produce the nutrient feed. Farmers could have it in two years.

    Perennial crops are also ridiculously underused in overall food supply chains. They are more difficult to monetize in existing commodity forms because their overall system value is not captured numerically.

    I think it probably has something to do with this:

    As plants reach maturity, there’s less additional biomass accumulated year after year. At least that’s how i imagine it, based on animal growth. Like for cattle that’s true. They grow and after 6 months i think they already have like 50% of the weight of a grown-up animal? And if you let them grow for 10 years, they would only have twice the weight than after 6 months but you pay 20x the cost to keep them alive so it doesn’t pay off at all (20x the cost for 2x the yield means only 10% of efficiency). That’s why they’re slaughtered early. I suspect a similar reason applies to plants and why they are eaten early.

    Edit: i looked up the numbers for cow and calf (child cow) weights (here and here):

    • At birth: 30 kg
    • After 2 months: 100 kg
    • After 6 months: 200 kg
    • After 12 months: 400 kg
    • Mature: 600 kg
