Happy to announce the publication of our article in Nature Ecology & Evolution on adaptive zone evolution in terrestrial mammal carnivores. Over the next few days, I’ll share the major results—and by extension, take you on a tour of carnivore evolution. (rdcu.be/6okG1hVhvtHa) 1/n

here are some space fireworks, happy 4th of july 🎆🌌
The brilliant tapestry of young stars flaring to life resemble a glittering fireworks display in this Hubble Space Telescope archival image.

The sparkling centerpiece of this fireworks show is a giant cluster of thousands of stars. 

The nebula reveals a landscape of pillars, ridges, and valleys. The pillars, composed of dense gas and thought to be incubators for new stars, are a few light-years tall and point to the central star cluster. Other dense regions surround the pillars, including reddish-brown filaments of gas and dust. The red dots scattered throughout the landscape are a rich population of newly forming stars still wrapped in their gas-and-dust cocoons. The brilliant blue stars seen throughout the image are mostly foreground stars.

The red colors in the nebulosity represent hydrogen; the bluish-green hues are predominantly oxygen.

Caption credit: NASAA globular cluster that looks like a very dense, ball-shaped collection of many shining stars in colors of white, yellow-orange, and blue. Some stars appear a bit larger and brighter than others, with the brightest having faint cross-shaped diffraction spikes. The cluster’s stars are scattered mostly uniformly, with their density increasing toward the cluster’s core where they merge into a strong, bright-white glow.This image of Cassiopeia A resembles a disk of electric light with red clouds, glowing white streaks, red and orange flames, and an area near the center of the remnant resembling a somewhat circular region of green lightning. X-rays from Chandra are blue and reveal hot gas, mostly from supernova debris from the destroyed star, and include elements like silicon and iron. X-rays are also present as thin arcs in the outer regions of the remnant. Infrared data from Webb is red, green, and blue. Webb highlights infrared emission from dust that is warmed up because it is embedded in the hot gas seen by Chandra, and from much cooler supernova debris. Hubble data shows a multitude of stars that permeate the field of view.A prominent, eight-pointed star shines in bright white at the center of this image. A clumpy cloud of material surrounds this central star, with more material above and below than on the sides, in some places allowing background stars to peek through. The cloud material is a dark yellow closer to the star, and turns a pinkish purple at its outer edges. Combined together, the central star and its cloud resemble the delicate petals of a cherry blossom. The black background features many smaller white stars scattered throughout.

When a chatbot gets something wrong, it’s not because it made an error. It’s because on that roll of the dice, it happened to string together a group of words that, when read by a human, represents something false. But it was working entirely as designed. It was supposed to make a sentence & it did.

Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.
