A decades-old idea—tinkering with light’s quantum fluctuations to make a large interferometer even more sensitive—has now been implemented.

Researchers have outlined a recipe for fashioning subwavelength optical components from plasmonic antennas.

A subtle quantum interference effect may offer a path to engineering all-optical logic gates and switches.

The key is to feed the bubbles a balanced diet of hydrogen and oxygen before they have a chance to grow.

Looking ahead, a central question will be whether to continue relying on nuclear power.

The Association of American Universities is pushing to institute new methodologies, but success will require big changes by academic departments.

As fields get stronger and electronics improve, demand for pulsed magnets is growing; the newest lab is in China.

A new polar-orbiting satellite is only a temporary fix for a more durable spacecraft that has been starved of funding.

Chemists have long held that there are two ways in which a molecule can break apart. But recent results show a third possibility, and its discovery may have far-reaching implications.

In 1980, telescopes revealed that one of Saturn’s rings is centered at the orbit of Enceladus, a medium-sized Saturnian moon. It was the first hint that Enceladus is a world like no other.

Undergraduate physics problem sets and textbook examples often assume prior knowledge that is more common in men than in women. Could that difference be deterring women from pursuing careers in physics?

An unappreciated symmetry of electrodynamics enables experimenters to fabricate coherent perfect absorbers, devices that act like lasers run backward.
