Oh, that is fascinating. Something to add to the benefits of real trees.

Taiping is one of my favorite cities, one of the wettest places I know.

Of all the wild animals I interacted with in Indonesia and Malaysia in my years there, I have the strongest memories of gibbons, orangutans, and hornbills.

That is thrilling, not only to find the photos, but to buy the same cookies locally. I wonder how many bakeries are still owned by the same family.

Thank you, I’ll find some.

Thank you for this. It’s not always clear from outside what the truth is, but as you show us, he was an exceptionally vile person.

Interesting! My understanding is that they are like pine nuts, but I've never had one.

Nice, though it does startle me to see palms in Oregon.

You may find the xenohormesis literature interesting. I disagree with David Sinclair on a number of things, but he is right about this. It gets a lot of attention in my next book.
Xenohormesis: Sensing the Chemical Cues of Other Species
Many plant molecules interact with and modulate key regulators of mammalian physiology in ways that are beneficial to health, but why? We propose that…

“carnivorous “death-ball” sponge” is the new biology term of the week!

It’s a very interesting paper, and appeals to me both as a plant physiologist/biochemist and as a vegan.

First, chestnut is not extinct and only the mature trees are gone. Second, genetic engineering has been done with chestnuts, some mistakes were made, and the project failed. Most chestnut breeders now have a preference for non-GE approaches. GE is going to be essential despite this opposition.

Trees can be very difficult experimental subjects. For example, the vascular cambium, a thin layer between the wood and bark, produces all the wood in the world. It is hard to study a fragile layer of cells between two very hard layers, so we use Arabidopsis instead. So, it's a tree.

I study trees for a living. I decided a long time ago that Arabidopsis is an honorary tree.
