I climb a lot around the forests where I live in Switzerland. In one area there are a lot of yew trees - deadly to mammals. Just 30 grams of the needles will stop your heart. The bright red berry tastes very nice and isn't poisonous but the seed, if just one seed has a crack in it and you swallow it it will stop your heart in about thirty minutes. German kings have used it to kill themselves after being defeated by Roman armies so that they don't have to surrender.
Anyway, there's an animal here, I assume marmots, that swallows the berries whole and shits them out as a half-digested diarrhea onto the tops of rocks, logs, anywhere high enough to mark their territory. Probably better than shitting out a charcoal briquette that you hope won't roll over... but they seem to know not to chew and crack the seeds.

They are planted in graveyards in the UK, it prevents grazing animals from entering and soiling up the place. The animals seem to know to keep away. They cant nibble the grass without getting a mouthful of the needles.

I’ve heard a different reason for their presence in graveyards: because yew kills grazing mammals that eat it, it was cut down everywhere that people grazed animals, which excluded graveyards

My understanding is that churches were built next to yew trees, not yew trees planted next to churches.
Pre-Christian religions had many associations with yew trees (they live for a long time, give off mildly hallucinogenic gasses on hot days, discourage animals), and so built their holy sites around them. When Christianity came to Britain, churches were deliberately built on pagan holy sites to overrun the old religions, in the same way that early Christianity took over roman holy days (Saturnalia -> Christmas, Lemuria -> All Saint's Day). This led to churches being built next to sites with copious yew trees.

There has to be a term for these very specific claims. 30 g in 30 minutes? Give me LD50 numbers.

Taxine alkaloids[0]
The estimated lethal dose (LDmin) of taxine alkaloids is approximately 3.0 mg/kg body weight for humans.[27][28] Different studies show different toxicities; a major reason is the difficulty of measuring taxine alkaloids.[29]
It goes on to say that rats are ~20mg/kg, which would put a human at somewhere less than 1.4grams.
Which is close enough to, "any exposure at all will kill".
> Which is close enough to, "any exposure at all will kill".
How much is in one seed?
I could only find a few sources saying that you would need to eat about 50g of the needles to reach the LD, and that's... A lot. There's no way a child would accidentally manage that, for example (even assuming LD for a child is much lower). But I couldn't find specific numbers for seeds.
Not being a killjoy here, I grew up around yew trees and I was always told to be careful of them, but not with any sense of panic that would suggest "any exposure at all will kill”. I think you'd have a bad time even with low exposure but death seems unlikely by accident.
This reminds me of the old “bats use sonar and can fly super precisely without crashing into each other in pitch black” and then it turns out that they crash into each other all the time.

We covered yew extensively in toxicology class in vet school, but I didn't know about any animals that eat the berries. My favorite fact about yew is that the Iowa State Lloyd Veterinary Center is named after a toxicologist, yet has yew planted for decoration all around the building.

There was a yew bush on my walk to primary school. When berries were in season, I used to pick and squish the berry between my fingers because the shape was unique (berry with a seed that sticks out‽) ands its slimy feel. Thank goodness it never amounted to anything more, even through transdermal absorption.

We had them in our yard growing up, I recall regularly playing with the berries for the exact same reason. Funny enough my dad did warn me not to eat it, but based on this post eating the berry itself would have been one of the few ways it’s not toxic. Had no idea about the rest of the plant being so toxic until today.

Oh wow I think we had these on the way to school when I was a kid too. Everyone told us not to eat them so we used to put the berries in our mouth and spit them out to show how tough we were. Wow we were very very stupid kids.
seszett 2 hours ago [-]
I think one of the problems is people thinking kids are more stupid than they are, and blanket "don't do that" statements without explanations don't really work for kids.
If they had told you they were highly poisonous instead of just telling you "not to eat them" you might have taken them more seriously. And if they had given you a taste of the red berry around it (which is sweet but not that special either, and the texture is not great) you might just have thought it was not necessary to play with them at all.
But that requires education at all levels, around here (Belgium) I sometimes see parents who seem deadly afraid of anything nature, I tell my kids to eat blackberries and they softly tell their kids next to us not to do that. You end up with generations who just don't know anything about what's around them and will eventually do stupid things.
vidarh 2 hours ago [-]
It takes longer than people tend to think before kids learn to infer things well at all, and so being explicit about causal chains tends to make kids more likely to take advice. E.g "put your coat on" might not lead the child to think it is cold, and even a "put your coat on, it's cold outside" might still not lead the child to realise that means they'll freeze without the coat. A lot of tantrums would be avoided if parents were more explicit about why they're giving certain advice.

For that, parents would need time. But if we have to spend half of our day with work or work-related tasks (commute, lunch break)...
Society (or let's be real, capitalism) forces us to work unhealthy amounts of hours and then wonders why there aren't enough children and of the children that remain, they dumb down every year...

Well, Mr. Oatmeal is apparently repeating an urban legend. I look at a wombat, and no way do I believe that thing can move at 25 mph (40 kph). I found a piece[0] which indicates this might have been some confusion as to metric vs imperial decades ago that was then retransmited through the ages.
We have four on the boundaries of our property. My 'Goldidor' (Labrador/retriever cross) has given chase a few times and has struggled to keep up. When they run they RUN. Maybe not pushing 40kph, not not far from it...

And yet the very article that you refer to confirms that anecdotal reports by the biologists studying these very animals report that during breeding seasons that the male Southern Hairy-Nose Wombat can reach these speeds in bursts:
>South Australian wildlife biologist [A/Prof] David Taggart has studied the southern hairy-nosed wombat since 1993. In the 2008 and 2024 editions of Strahan's mammal book, he writes that the southern hairy-nosed species can run at 40 kph. "I can confirm that I have clocked this species running at just over 40 kph, although they can't maintain that for long."

A bit of a tangent but I've read this phrase almost verbatim in another article[1] today:

The other article [1] quote:
> It’s “an impressive step,” said Jack Szostak (opens a new tab), who studies the origins of life at the University of Chicago and was not involved in the research. “I don’t know of any other effort to put together an artificial cell from biological components that has progressed so far.”
Are these editorial guidelines to get an independent read? Just coincidence? I don't think they are LLM bits because I expect better from these magazines, but it's too eerily similar.
Yes, good science writing almost always gets an opinion from someone not involved in the research for the article. I would guess varying definitions of "not involved" depending on the repute of the publication.

I think this is just a way of breaking up the quote that adds attribution in the middle. Probably a common reporting phrasing more so than an LLM invention (Or maybe it's a real quote in both cases, but they used an LLM to write parts of the article, just making sure the quotes are correct in the end).
