12 分钟With influencers selling us crap all over the place and facts feeling so slippery,
you need the podcast Science Versus.
This season, we're tackling ADHD, fluoride, bird flu, and even squirting.
It feels different when I pee and it feels different when I squirt.
If I were pregnant, I would avoid drinking fluoridated water.
We've done our homework and this is the season you need to be listening to.
New Science Versus is out now.
That's Science VS.
For Scientific American Science Quickly, I'm Rachel Feltman.
Even if you don't know what the International Union for Conservation of Nature's red list is off the top of your head,
I can pretty much guarantee you've heard of it.
The IUCN keeps tabs on the conservation status of living organisms all over the globe.
Giant pandas are listed as vulnerable on the red list,
the Asian giant tortoise is marked as critically endangered,
and lots of other charismatic megafauna have gotten not-so-honorable mentions too.
But the IUCN recently sounded the conservation alarm for some creatures many of us spend a lot less time thinking about.
Fungi.
In March, the IUCN announced that its experts had assessed 482 fungi species for the first time,
bringing the redless fungal members up to 1,300.
Around a third of those species are at risk of extinction.
