The rise of new extremist groups has served as both an impetus and test-case for Neil Johnson’s models of terrorism and insurgency.

The mathematician Svitlana Mayboroda and collaborators have figured out how to predict the behavior of electrons — a mathematical discovery that could have immediate practical effects.

The physicist and curios collector hopes to reveal the hidden structure lurking in the subatomic world.

Even in the age of sun-observing satellites, astronomers like Jay Pasachoff still seek out total solar eclipses for the tales they can tell about our sun.

The pot-stirring string theorist and quantum gravity theorist never sits still for long.

The first major results from the Dark Energy Survey signal the start of a new era of cosmology.

Textbooks say that the moon was formed after a Mars-size mass smashed the young Earth. But new evidence has cast doubt on that story, leaving researchers to dream up new ways to get a giant rock into orbit.

Astronomers thought that all Type Ia supernovas shine with the same brightness, making them incredibly useful cosmic yardsticks. But uncertainty over what causes these explosions has led researchers to reconsider their assumptions.

The astrophysicist Andrea Ghez spent two decades proving that a supermassive black hole anchors the center of the Milky Way galaxy. Her new plan? Test what happens when things get too close.
