A starry sky can be stunning—even inside a hospital emergency room.

But instead of celestial bodies sparkling in the night, doctors in South Korea were gazing at bright brain lesions punctuating a magnetic resonance imaging (MRI) scan. The resulting pattern, called a "starry sky," meant that their 57-year-old patient had a dangerous form of tuberculosis. The doctors report the case in this week's issue of the New England Journal of Medicine.

The man had previously been treated for the infection in his lungs but came into the hospital's emergency department after two weeks of unexplained headaches, neck pain, and tingling in his right hand. The MRI and Computed-Tomography (CT) scans clearly revealed the problem: rare nodules and lesions, called tuberculomas, speckling his lungs and central nervous system, including both cerebral hemispheres, the basal ganglia deep inside the brain, the cerebellum at the back of the brain, the brain stem, and the upper spinal cord.

On Thursday, researchers at Carnegie Mellon University unveiled LegoGPT, an AI model that creates physically stable Lego structures from text prompts. The new system not only designs Lego models that match text descriptions (prompts) but also ensures they can be built brick by brick in the real world, either by hand or with robotic assistance.

"To achieve this, we construct a large-scale, physically stable dataset of LEGO designs, along with their associated captions," the researchers wrote in their paper, which was posted on arXiv, "and train an autoregressive large language model to predict the next brick to add via next-token prediction."

This trained model generates Lego designs that match text prompts like "a streamlined, elongated vessel" or "a classic-style car with a prominent front grille." The resulting designs are simple, using just a few brick types to create primitive shapes—but they stand up. As one Ars Technica staffer joked this morning upon seeing the research, "It builds Lego like it's 1974 ."

Fitness tracker company Whoop has upset some long-time customers by ending an upgrade system that promised free hardware upgrades to anyone who had a subscription with the company for at least six months.

Whoop makes fitness tracker bracelets that let users access things like sleep tracking, menstrual tracking, and electrocardiograms (ECGs) via a subscription companion app. Since the first Whoop wearable came out in 2015, the Boston-based company’s business has been built on subscriptions. Whoop has traditionally lured customers in by giving its hardware away for “free” to Whoop app subscribers. Further, customers who subscribed to the Whoop app for at least six months got access to free hardware upgrades.

“Instead of purchasing new hardware every time an updated model is produced, WHOOP members receive the next-generation device for free after having been a member for six months or more,” said a webpage on Whoop’s website that is no longer active but was accessible as recently as March 28, as reported by The Verge and confirmed via the Internet Archive’s Wayback Machine .
