Katherine Freese, a physicist who will soon lead the Nordic Institute for Theoretical Physics, reflects on the hunt for dark matter and how dark matter heating may have produced the first stars.

Newly discovered patterns in evolution may help scientists make accurate short-term predictions.

The cosmologist David Spergel explains why a widely publicized gravitational-wave discovery could be wrong, and how the “overreaching” study could affect the public’s perception of science.

Chao-Lin Kuo, who helped design the experiment that claimed to have found evidence of gravitational waves from the Big Bang, isn’t bothered by criticism that cosmic dust may account for his results.

Surprising oil drop experiments suggest that the quantum world may not be as strange as advertised.

When scientists traced a museum rock back to its origins, they uncovered mysteries about the early solar system.

Three groups of experimentalists have independently observed a strange state of matter that forms from three particles of any type and at any scale, from practically infinitesimal to infinite.

A scientist at Bell Labs has started construction of a topological qubit, which could be the building block of a robust, scalable quantum computer.

Experimentalists have pinpointed the microscopic structure of waves inside high-temperature superconductors, which could be the key to understanding the complex materials.
