Scientists have developed a breakthrough food supplement that could help save honeybees from devastating declines. By engineering yeast to produce six essential sterols found in pollen, researchers provided bees with a nutritionally complete diet that boosted reproduction up to 15-fold. Unlike commercial substitutes that lack key nutrients, this supplement mimics natural pollen’s sterol profile, giving bees the equivalent of a balanced diet.
Though interesting they’ve been staving it off rather directly; you have millions of colonies die, but you can breed millions more per year to keep the population stable. It is more expensive, and a bit dark for the bees.
