Roughly 4.5 million years ago, the sun passed remarkably close to two intensely bright stars whose radiation flooded nearby space — and the encounter left a ghostly scar that astronomers can still detect today, according to a new study. The research team says the...
For the first time, scientists have created detailed, 2D maps of the sun's outermost atmosphere. This feat was accomplished using data from NASA's Parker Solar Probe, which has been dipping in and out of the sun's atmosphere, called the corona, since 2021. Parker is...
The latest United Nations Climate Change Conference (COP30) concluded in November without a roadmap to phase out fossil fuels and without significant progress in strengthening national pledges to reduce climate-altering greenhouse gas emissions. In aggregate, today’s...

Let’s say an environmental scientist is studying whether exposure to air pollution is associated with lower birth weights in a particular county. They might train a machine-learning model to estimate the magnitude of this association, since machine-learning methods...
Artificial intelligence can enhance decision-making and enable action with reduced risk and greater precision, making it a critical tool for national security. A new program offered jointly by the MIT departments of Mechanical Engineering (Course 2, MechE) and...
As language models (LMs) improve at tasks like image generation, trivia questions, and simple math, you might think that human-like reasoning is around the corner. In reality, they still trail us by a wide margin on complex tasks. Try playing Sudoku with one, for...
