IN an earlier paper1, we have described a new type of interferometer which has been used to measure the angular diameter of radio stars2. In this instrument the signals from two aerials Ax and A2 (Fig ...

Numerical simulations provide a mechanism that explains how celestial objects such as stars and galaxies can generate ordered, macroscopic magnetic fields. The mechanism arises from turbulence — ...

An AI model developed by Google DeepMind is giving athletes like Maddie Mastro new insights into how their bodies move. After leaning on its partnership with OpenAI, Microsoft is playing catch-up in ...
