This is excellent. We just need another 50 or 100 similarly minded billionaires. Though taxes are more accountable and probably yield less idiosyncratic outcomes

Clearly this result is model-dependent: those raw skulls are indeed quite distorted, and your phylogenetic analysis is based on a virtually reconstructed skull. How sensitive are your conclusions to model parameterisation or model assumptions?

Happy Rosh Hashanah y'all.

Illustration of three people standing on a hill beneath a huge orange sun. Large black text at the top reads: ‘It’s a Beautiful Day to Yell At God.’ One figure raises their arms and shouts ‘WHAT THE FUCK?’ while another says ‘COME OUT! WE JUST WANNA TALK.’ Bold text in the corner says ‘FACE US YOU COWARD.’

Follow me into #PALARQUE ’s coring campaign in the Cape Region I'll be posting here this week! Co-led by my friends & almighty palynologists Saúl Manzano & Lynne Quick, the project explores fynbos Holocene & Anthropocene dynamics in the #Cederberg mntns., N Cape Region. Part of my 💜 belongs here! 1/

Five people stand in a row on a terrace with a stone balustrade, smiling at the camera. From left to right: Saul Manzano, Graciela Gil Romera, Luke Aurilis, Juan Ivars and Lynne Quick. Behind them rises Cape Town’s Table Mountain, lit by the soft colors of dusk. The group looks relaxed and cheerful, dressed casually in jackets, sweaters, and trousers. The city spreads out below the terrace with rooftops and buildings visible in the fading light.

A wide view of Cape Town at sunset, framed by two iconic mountains. On the left rises the flat-topped Table Mountain, while on the right stands the conical peak of Lion’s Head. Below them, the city stretches out with clusters of houses and buildings nestled among green hills. The sky glows in soft shades of blue, purple, and gold as the sun dips behind the mountains, casting a tranquil light across the landscape.

Which are more painful, desk rejections or rejections following peer review?

Oded Rechavi @odedrechavi.bsky.social · 25d

If manuscript rejections arrived fast, instead of after >6 months, they would be 10 times less painful

One of the truly compelling features of using an LLM as a coding tutor, rather than, say, asking human coders for advice at Stack Overflow, is that the LLM is polite, never complains about your failure to provide a reproducible example, and is uninterested in being an arsehole.

If you want to overlook the largest case of copyright theft in history, the abuse of workers in the global south, the vast drain on essential resources, the huge proliferation of scams using this tech and the tidal wave of junk ruining web searches, so you can code faster, I don't know what to say.

by contrast, Decalobanthus peltatus (Convolvulaceae) belongs to a small (~20 spp) and recent Malesian/inner Pacific radiation of fast-growing vines. It probably arrived in Australia within the past million years or so

Crab-like creatures are famed for having evolved five times in evolutionary history. But anteaters have evolved at least 12 times--in half the evolutionary span. Cool story by @jakebuehler.bsky.social for @science.org

‘Things keep evolving into anteaters.’ Odd animals arose at least 12 separate times

Findings speak to the dramatic impact ants and termites can have on mammalian evolution

Decalobanthus peltatus (previously within polyphyletic Merremia) is a megatherm Convolvulaceae vine colonising cyclone-damaged Daintree rainforest (NE Queensland). Totally feral on Pacific Islands, esp where not native (no surprise). See George Staples' superb revision tinyurl.com/42dk4pe2 🌿🧪

If you haven’t read THE NATION OF PLANTS, a short book by Stefano Mancuso (2019)… you should!

WHETHER BURUNDIAN, ITALIAN OR ICELANDIC, humans are the most accomplished predators. Like a lion observing, sleepy and satisfied, the piece of the savannah that is its territory, with the serene awareness that no other animal can contest his sovereignty over it, the human race considers the entire planet as something under its exclusive jurisdiction. Earth, the home of life, the only place we know of in the universe able to host it, is considered by humans as neither more nor less than a simple resource; to be eaten, to be consumed.
Something similar to a gazelle in the eyes of an always-hungry lion.
That this resource might come to an end, putting at risk the very existence of our species, does not seem to interest us. Have you ever seen that science fiction film in which some really wicked alien species, after having consumed the

resources of countless other planets, swoops down on the Earth like a swarm of 'grasshoppers from space' intent on turning it into a wasteland? Those aliens are us. Only the other planets still left to be destroyed after Earth do not exist. We would do well to understand this as soon as possible.
The consumption of organic material produced by other living beings is typical of animal life. Not being able, as plants are, to fix the energy of sunlight autonomously, animals must rely on the predation of other living beings to ensure their survival. This is why plants are always pictured at the bottom of those typically pyramidal illustrations that we see everywhere bearing the name of the food pyramid, or the ecological pyramid, or the trophic pyramid.
Whatever the name, the concept is always the same.
There is a pyramid with plants, the producers, occupying the lowest level, and then proceeding upwards through the various trophic levels. First, the herbivores that eat plants, then above them the carnivores that eat meat, and then the omnivores that eat both plants and meat, and so on, until you get to the apex predators, who are at the top of the food chain.
I have always found these representations of plants as the lowest level of a pyramid to be rather ungenerous, not to say wrong. It would seem to me more correct that the top should be reserved for the organisms that produce chemical energy, rather

than those that consume it. I mean, in a car isn't the most important part the engine? All the rest is not essential. Well, plants are the engine of life, the essential part; all the rest is just car body.
