A proposed theory of gravity does away with dark matter, even as new astrophysical findings challenge the need for galaxies full of the invisible mystery particles.
Can a fluid analogue of a black hole point physicists toward the theory of quantum gravity, or is it a red herring?
In a monumental set of experiments, spread out over nearly two decades, biologists removed genes two at a time to uncover the secret workings of the cell.
The impasse in math and science instruction runs deeper than test scores or the latest educational theory. What can we learn from the best teachers on the front lines?
Computer scientists have come up with a bounded algorithm that can fairly divide a cake among any number of people.
The surprising discovery of a massive, Milky Way–size galaxy that is made of 99.99 percent dark matter has astronomers dreaming up new ideas about how galaxies form.
Computer scientists can prove certain programs to be error-free with the same certainty that mathematicians prove theorems.
Just months after their discovery, gravitational waves coming from the mergers of black holes are shaking up astrophysics.
Irrationality may be a consequence of the brain’s ravenous energy needs.
