As the founding director of a new institute for fundamental research in Rwanda, the physicist Omololu Akin-Ojo hopes to stem the brain drain of Africa’s brightest minds.

The recent discovery of some of the first galaxies in the universe illuminates the darkest era in cosmic history.

A proposal for building wormhole-connected black holes offers a way to probe the paradoxes of quantum information.

A problem confronts cosmology: Two independent measurements of the universe’s expansion give incompatible answers. Now a third method, advanced by an astronomy pioneer, appears to bridge the divide.

A recent neutron star merger has defied astronomers’ expectations, leading them to question longstanding ideas about neutron stars and the supernovas that create them. “We have to go back to the drawing board.”

By watching for a special kind of flare, astronomers have identified the fingerprints of an Earth-size planet orbiting a distant star.

The apparent paradox of the chicken and the egg smells like “turtles all the way down.” This puzzle shows how biology and physics can overcome infinite regress.

Rogue waves — enigmatic giants of the sea — were thought to be caused by two different mechanisms. But a new idea that borrows from the hinterlands of probability theory has the potential to predict them all.

By exploiting randomness, three mathematicians have proved an elegant law that underlies the chaotic motion of turbulent systems.
