A vegan friend needed a plant specialist a few days ago : opponents to vegan regimes claimed that plants and animals suffer the same when killed, so makes no sense to be vegan.

The buff-tip moth (Phalera bucephala) has mastered a very particular kind of camouflage.
When they close their wings up, they resemble a broken twig.
Native to large parts of Europe, there's regional pattern variation that reflects the local tree species. This one best resembles birch twigs?

Computational design of sequence-specific DNA-binding proteins
Nature Structural & Molecular Biology, Published online: 12 September 2025; doi:10.1038/s41594-025-01669-4The authors develop a computational method to design small DNA-binding proteins (DBPs) that target specific sequences. Designed DBPs show structural accuracy and function in both bacterial and mammalian cells for transcriptional regulation.
