Astronomers have found a background din of exceptionally long-wavelength gravitational waves pervading the cosmos.

Jellyfish and other aquatic creatures embody solutions to diverse problems in engineering, medicine and mathematics. John Dabiri, a fluid dynamics expert, talks with Steven Strogatz about what jellyfish can teach us about going with the flow.

By treating molecules as geometric tessellations, scientists devised a new way to forecast how 2D materials might self-assemble.

Wave-science researcher Ton van den Bremer and Steven Strogatz discuss how rogue waves can form in relatively calm seas and whether their threat can be predicted.

By measuring inflated helium nuclei, physicists have challenged our best understanding of the force that binds protons and neutrons.

The marine geochemist Chris German brings decades of experience studying seafloor hydrothermal vents to NASA’s preparations for visits to other ocean worlds in our solar system.

The puzzling behavior of black hole interiors has led researchers to propose a new physical law: the second law of quantum complexity.

Renate Loll has helped pioneer a radically new approach to quantum gravity. She assumes that the fabric of space-time is a blend of all possible fabrics, and she has developed the computational tools needed to calculate the far-reaching implications of that assumption.

Several areas of physics suggest reasons to think that unobservable universes with different natural laws could lie beyond ours. The theoretical physicist David Kaplan talks with Steven Strogatz about the mysteries that a multiverse would solve.
