ChatGPT Health performance in a structured test of triage recommendations
ChatGPT Health launched in January 2026 as OpenAI’s consumer health tool, reaching millions of users. Here, we conducted a structured stress test of triage recommendations using 60 clinician-authored vignettes across 21 clinical domains under 16 factorial conditions (960 total responses). Performance followed an inverted U-shaped pattern, with the most dangerous failures concentrated at clinical extremes: non-urgent presentations (35%) and emergency conditions (48%). Among gold-standard emergencies, the system under-triaged 52% of cases, directing patients with diabetic ketoacidosis and impending respiratory failure to 24–48-hour evaluation rather than the emergency department, while correctly triaging classical emergencies such as stroke and anaphylaxis. When family or friends minimized symptoms (anchoring bias), triage recommendations shifted significantly in edge cases (OR 11.7, 95% CI 3.7-36.6), with the majority of shifts toward less urgent care. Crisis intervention messages activated unpredictably across suicidal ideation presentations, firing more when patients described no specific method than when they did. Patient race, gender, and barriers to care showed no significant effects, though confidence intervals did not exclude clinically meaningful differences. Our findings reveal missed high-risk emergencies and inconsistent activation of crisis safeguards, raising safety concerns that warrant prospective validation before consumer-scale deployment of artificial intelligence triage systems. A stress test of ChatGPT Health triage revealed missed high-risk emergencies and inconsistent activation of suicide-crisis safeguards, raising safety concerns for consumer-scale deployment.

Webb Identifies Supernova Progenitor Star in NGC 1637 | Sci.News
Using the NASA/ESA/CSA James Webb Space Telescope, astronomers have for the first time identified the progenitor of a nearby supernova -- a red supergiant star cloaked in thick, dust-rich shrouds that made it invisible to previous observatories.

Scientists reveal a giant gravitational anomaly beneath Antarctica that could impact studies of ice, sea level, and Earth's internal dynamics; the phenomenon is linked to deep mantle movements and the geophysical monitoring industry.
A new model based on seismic data shows a gravitational anomaly, in the so-called Antarctic Geoid Low, that has intensified in the last few million years, altering local gravity and raising concerns about indirect impacts on ice and sea level.

Measuring the expansion of the universe with cosmic fireworks
That the universe is expanding has been known for almost a hundred years now, but how fast? The exact rate of that expansion remains hotly debated, even challenging the standard model of cosmology. A research team at the Technical University of Munich (TUM), the Ludwig Maximilians University (LMU) and the Max Planck Institutes MPA and MPE has now imaged and modelled an exceptionally rare supernova that could provide a new, independent way to measure how fast the universe is expanding.
