Doing great work. Thanks.
And of course! Sterols! What I've been saying all along!
carols, what I've been singing all along
Well this story is the bee's needs!
Colonies fed with the enriched diet were more likely to continue rearing brood up to the end of the three-month period, whereas colonies on sterol-deficient diets ceased brood production after 90 days.
Uhh m not crazy right, that's the same thing?
I’m with you, it’s confusing. But I think what it means is this:
The study ran for 90 days. Non-sterol bees had stopped doing bee sex by then. Sterol bees were doin it all the way up to the end of the 90 days - and then the study ended. We can therefore assume they wanted to continue having freaky beedsm sex for even longer.
I could begrudgingly accept that, if that's what is it was
Some were observed brooding for up to 12 weeks!
Amateurs, I've been brooding for years!
one group continued to the end of the study period, the other group had stopped by the same time
or, one group stopped doing a thing, and the other group didn't show signs of stopping
Gotta be AI bullshit. But I'm reading it as, group A never stopped while group B stopped breeding at the end of the period.
Why in hell is poorly written text "AI bullshit" now? An LLM would probably write that in a clearer way.
Were articles irreprehensibly written up to 3 years ago?
Fuckin old men of Restelo!
For me it's because the study is dated August 2025. Everything after November 2022 is suspect.
Allow native wild flowers and plants to grow and get rid of the damn grass.
It’s the bees needs.
It has what bees crave!!
TL;DR: They found six sterols found in pollen could be produced from engineered yeast and increased brood production dramatically. The article talks about them as essential nutrients but is it possible they are signaling molecules affecting bee behavior?
Your second sentence is your own thoughts, not part of the tldr summary, right? I think you should make that separation clear (in Wikipedia terms, I'm flagging this as "original research").
In the new study, the research team succeeded in engineering the yeast Yarrowia lipolytica to produce a precise mixture of six key sterols that bees need. This was then incorporated into diets fed to bee colonies during three-month feeding trials. These took place in enclosed glasshouses to ensure the bees only fed on the treatment diets.
Key findings:
- By the end of the study period, colonies fed with the sterol-enriched yeast had reared up to 15 times more larvae to the viable pupal stage, compared with colonies fed control diets.
- Colonies fed with the enriched diet were more likely to continue rearing brood up to the end of the three-month period, whereas colonies on sterol-deficient diets ceased brood production after 90 days.
- Notably, the sterol profile of larvae in colonies fed the engineered yeast matched that found in naturally foraged colonies, suggesting that bees selectively transfer only the most biologically important sterols to their young.
"Oh, so we can kill 15 times more before it becomes an issue" - Monsanto, probably
And then goes on to kill 30 times more.
For anyone wanting to save the bees, look into making bee hotels. If you have a power drill and a variety of small bits, easy money. Spend a half hour watching videos, not too much to learn. They're basically free to make if you can lay your hands on some wood or non pressure-treated lumber. Chunk the old one every year and roll an new one.
Damned cool when you see your first guests having waxed off the entrance hole!
I researched that, maybe it's just in Australia but apparently the bees here don't use those bee hotels? They apparently just get stacked with earwigs. I read the best thing you can do for bees here is plant native flowering plants like the Bottle Brush, and let leaves biodegrade naturally instead of hoovering em up.
We need more food and less pesticides for our bees more than houses for bees in the US.
No really, it's really bad. Flowering seasons across much of the south and west have been reduced, farmland and pesticides everywhere, people don't grow gardens in suburbs and everything is suburbs.
In the early 2000's I could drive across country and have to stop at every gas station to clean my windshield. Now on the same exact route my windshield is almost spotless after 5 hours on the road. This is really, really bad. It's not just bees, it's everything.
Also please check whether honey bees are native in your area. If they're not (or if there's too many of them) it leads to decline of other bee species and threatens other pollinators and rare plant species.
Not sure what that has to do with my comment? Bee hotels are for solitary bees, not honey bees. Exactly what we want!
Yep, sorry. Still I kind of think it's worth repeating over and over, so treat is as not aimed at you :)
I am expecting the Trump Regime to take this miracle and use it to raise Murder Hornet colonies or something.
Genetically engineered to be attracted to minorities and immigrants
Fun facts: "killer bees" are also known as "africanized bees". In the 1970s there was great alarm in the US about the spread of africanized bee strains because they're so much more aggressive than European bees. There was even a terrible horror movie about it, but this particular catastrophe never materialized. I had a friend in graduate school in the '90s who was part of a team of scientists investigating the problem. It turns out that if you raise an africanized queen in a temperate climate, the bees she produces are no more aggressive than European bees; likewise, a European queen raised in a hot, tropical climate produces bees just as hyper-aggressive as typical africanized bees. So the entire thing was just bee racism all along. Bracism?
Of course global heating is going to make this a bigger problem everywhere, but fortunately we'll be fucked a lot worse by all the other problems this is going to produce.
Um, isn't this like majorly good news? Like maybe among our most important discoveries?
Sorta. If you're a beekeeper I can see this being a major deal. Not clear on how hard this yeast is to grow or how well the process scales.
Bees got a threefold problem, and we need to get at the roots of the issue.
-
Pesticides and herbicides. Won't happen, but governments need to ban these products for consumers, restrict them to professionals. Karen and Ken don't need a perfect lawn sacrificing the bottom of the food chain.
-
We need to grow more, and more indigenous, plants of all kinds. Working on it in my yard, doing well so far. Last year the bumblebees were so loud I thought it was construction on the next block over. :)

Verona mites are a monster issue. They came to America in the 90s and are whipping our ass. Haven't looked into beekeeping for awhile, not sure where we're at with that.
Good for bee keepers, but most plants are pollinated by wild bees. So this could help, but doesn't really change much in the grand scheme.
The whole "save the bees" thing is about wild bees, not domesticated ones I think
This is the most uplifting science article I’ve read in a while. The process they describe in the article sounds long and involved with many dependent steps. Great work!
Hope they can get it to mass production. I have some bees in the area and would love to help the little guys.
QUICK. What flowers produce pollen high in Sterol.
Let it bee know they need sterol!
I thought that honeybees were the last bees that we should be saving since they harm native bee populations, which are move vulnerable.
The European honeybee in the Americas is kinda a double edged sword. It's an invasive species, which both steals resources from and spreads diseases to native bees. However, for better or worse at this point a good portion of agriculture is dependent upon the European honey bee.
... And they produce honey, which I like.
