A graduate student has created the first man-made biological leaf. It absorbs water and carbon dioxide to produce oxygen just like a plant. He did this by suspending chloroplasts in a mixture made out of silk protein. He believed it can be used for many things but the most striking one is the thought that it could be used for long distance space travel. Plants do not grow in space, but this synthetic material can be used to produce oxygen in a hostile environment. (Video)

Apparently there are places in the world where this is starting to happen? I wouldn’t know since Austin still has the summer dial turned up to like 8.5, and our trees don’t so much “change color” as “exhaustedly whither into a brown winter dormancy as if finally exhaling after the release of soul-crushing weight.”
This color-changing thing sounds nice though, I hope to check it out sometime!
PS - “Autumnal carotenoids” would make a great indie band name.
Help me to figure out what species is this!!!
*realizes joy division did some real quick fs photoelectron spectroscopy for their dumb album cover*
1) Joy Division’s 1979 Unknown Pleasures album cover actually features a data visualization from the first known pulsar, PSR B1919+21, discovered by Jocelyn Bell Burnell in 1967, and discovered by the band’s drummer in the Cambridge Encyclopedia of Astronomy.
2) It is not dumb.
La luce solare è una risorsa, e le piante competono per essa: un esempio è dato da questa immagine dove dei Prunus serrulata crescono lateralmente per sfuggire alla zona d’ombra creata dalle querce che hanno affianco. In questo modo riescono a ricevere la luce necessaria per la fotosintesi e quindi per vivere; questo fenomeno è noto come Eliotrpismo o Fototropismo ed è comune in tutte le piante.
