The early stages of a supernova explosion are revelatory in what they can reveal about stars that go boom. But while catching them immediately after they detonate has proven largely elusive, astronomers now think they have developed a foolproof way to spot a young supernova. Although we know what type of star will go supernova, we cannot predict when a …

Federal scientists report the first detection of tetrahydrocannabinol (THC) in human breath after people ate cannabis edibles, marking a careful but notable step toward measuring recent use outside a lab. There is a catch, though, and it is important. The signals vary widely from person to person and from one moment to the next, which means no one should rush …

A groundbreaking discovery has reshaped our perception of how fast galaxies evolved in the early universe. Astronomers have detected oxygen in the light from the galaxy JADES-GS-z14-0, the most distant known galaxy to date. This observation, published in Astronomy & Astrophysics, reveals that complex chemical enrichment was already underway just 300 million years after the Big Bang. The galaxy’s light …

OpenAI, which is expected to launch its GPT-5 AI model this week, is making updates to ChatGPT that it says will improve the AI chatbot’s ability to detect mental or emotional distress. To do this, OpenAI is working with experts and advisory groups to improve ChatGPT’s response in these situations, allowing it to present “evidence-based resources when needed.” OpenAI acknowledges …

Welcome back to the Abstract! Here are the studies this week that boiled my blood, warmed my heart, and got permanently inked into my memory. First, a new look at some very old tattoos. Then: a posthumous discovery from a beloved defunct telescope, an update on lava planets, the adventures of translocated mole rats, and some provocative style tips from …

A scan that takes merely 10 minutes may be able to tell you whether you are at risk of having a heart attack and suffering from coronary artery disease.  Lynda Hollander, 64, a social worker and runner in West Orange, New Jersey, noticed her cholesterol levels had begun to rise after she hit menopause.  She decided to visit a cardiologist, …

We may receive a commission on purchases made from links. A mouse jiggler — as the name would suggest — is a device that is designed to “jiggle” a mouse. It’s designed to give a computer mouse a quick jiggle without a user’s presence. This begs the question: why would you need such a …

Scientists have uncovered a remarkable shift in how we understand insulin resistance and type 2 diabetes. Researchers from the University of Copenhagen revealed that everyone has their own unique response to insulin, challenging how the condition has traditionally been diagnosed and treated. This research takes a deep dive into the molecular makeup of muscle tissue and shows that insulin sensitivity …

Most exoplanets are discovered as they transit, or move across, their parent stars. But a new study details the opposite scenario: As a giant planet crossed its host star, peculiarities in its transit signature revealed a new discovery about the star itself — in particular, a spot that occupies an enormous 7% of the star’s surface and has lasted at …
