Physicists have long puzzled over a strange contradiction inside a family of minerals called rutile oxides. These materials all share the same crystal structure—but while some of them, like titanium dioxide, are firmly insulating, ...

The rise of AI has created an almost insatiable appetite for computing power. Training and running AI systems requires vast numbers of transistors, and engineers are now racing to pack more of them onto every chip. With their ...

Natural historians have many observational techniques in their toolkit for learning about the natural world: tagging animals with tracking devices, recording sounds, analyzing droppings or simply watching and counting. As ...

A new study has revealed an unexpected link between solar storms and the flux of high-energy cosmic rays arriving at Earth. The findings, made using one of the world's largest cosmic ray detectors, could open up a new way ...

Within their planetary systems, stars are continuously shaping their orbiting planets through gravity, radiation and magnetic forces. So far, this relationship has appeared to be a one-way street.

Lurking at the heart of the Milky Way, Sagittarius A* (Sgr A*) is a supermassive black hole four million times the mass of the sun, surrounded by a puzzling collection of young, massive stars whose orbits have long defied ...

From detecting the ripples of colliding black holes to imaging individual chemical bonds, mechanical transducers have repeatedly transformed our understanding of the universe. So far, however, the sensitivity of these devices ...

Physicists have long suspected that a peculiar quantum state lurks inside a class of materials known as kagome metals, but proving its existence has been elusive. Now, a team led by Yeongkwan Kim at the Korea Advanced Institute ...

For some time, researchers have used optical tweezers to manipulate tiny objects with incredible precision, using carefully controlled beams of laser light. So far, however, this technique has always come with strict limits ...

Physicists in China have observed five phases in localization physics within a single quantum system. Using an advanced photonic platform, the team, led by Yucheng Wang and Jingyun Fan at the Southern University of Science ...

Two U.S. physicists have suggested that the nine concentric rings surrounding the galaxy LEDA 1313424, also known as the Bullseye galaxy, could have emerged through the quantum behavior of particles of dark matter. Through ...

Physicists have long been drawn to the nonlinear Hall effect: a subtle variant of the classical Hall effect, in which an electric voltage appears perpendicular to a current flowing through a material. Unlike its classical ...

A team of U.S. researchers has designed a passive quantum error correction technique that enables qubits to correct their own errors. Demonstrated by Shruti Shirol and colleagues at the University of Massachusetts Amherst, ...

In the next few decades, many physicists are hopeful that nuclear fusion could become a realistic source of practically limitless energy. But before this can happen, it will be critical to ensure that reactors cannot be covertly ...

Two independent research teams have achieved a longstanding goal in physics: building a working nuclear clock. The devices, developed by Beichen Huang and colleagues at Tsinghua University and by Luca Toscani De Col and colleagues ...
