Machine learning decodes tremors of the universe

Researchers train a neural network to estimate — in just a few seconds — the precise characteristics of merging black holes based on their gravitational-wave emissions. The network determines the masses and spins of the black holes, where in the sky,…

Fine-tuning motivation in the brain

Neuroscientists have discovered a set of brain cells that influence the motivation of mice to perform tasks for rewards. Increasing the cells’ activity makes a mouse work harder or more vigorously. The neurons come with a feature that prevents the mous…
