Quantum mechanics is strange. A philosopher explains just how strange, and what it means for reality.

In a landmark series of calculations, physicists have proved that black holes can shed information, which seems impossible by definition.

It has been thought of as many things: a pointlike object, an excitation of a field, a speck of pure math that has cut into reality. But never has physicists’ conception of a particle changed more than it is changing now.

In a landmark series of calculations, physicists have proved that black holes can shed information — an apparent violation of Einstein’s theory of relativity.

Passing electricity through a piece of quartz crystal generates a pulse you can literally set your watch by. Set a time crystal melting, on the other hand, and it just might pulse with the deepest secrets of the Universe.

In the long road to nuclear fusion, scientists continue to confront one of the more prominent (and literal) bumps: edge localized modes (ELMs). These blobs form at the edge of a tokamak’s plasma swirl, caused by the interaction of the powerful, containing magnetic field and the sun-hot plasma.

Compressing simple molecular solids with hydrogen at extremely high pressures, University of Rochester engineers and physicists have, for the first time, created material that is superconducting at room temperature. Featured as the cover story in the journal Nature, the work was conducted by the lab of Ranga Dias, an assistant professor of physics and mechanical engineering.

Scientists have long theorised that there are other types of superconductor out there waiting to be discovered, and it turns out they were right: new research has identified a g-wave superconductor for the first time, a major development in this area

Contrary to conventional wisdom, a sufficiently small, cold object warms to the temperature of its surroundings faster than a warm object cools, according to a new theory.

In an incredible example of cosmic scales meeting the tiniest possible realm, scientists found that radiation including cosmic rays causes superconducting qubits to slip into disarray.

The existence of time crystals - a particularly fascinating state of matter - was only confirmed a few short years ago, but physicists have already made a pretty major breakthrough: they have induced and observed an interaction between two time crystals.

Researchers at Aalto University have developed a photovoltaic device that has an external quantum efficiency of 132 percent. This impossible-sounding feat was achieved using nanostructured black silicon, and could represent a major breakthrough for solar cells and other photodetectors. If a hypothetical photovoltaic device has an external quantum efficiency of 100 percent, that means that every photon of light that strikes it generates one electron, which exits through the circuit and is harvested as electricity.

A theoretical study could help physicists searching for a theory of quantum gravity.

Scientists have found a novel way to prevent pesky magnetic bubbles in plasma from interfering with fusion reactions—delivering a potential way to improve the performance of fusion energy devices. And it comes from managing radio frequency (RF) waves to stabilize the magnetic bubbles, which can expand and create disruptions that can limit the performance of ITER, the international facility under construction in France to demonstrate the feasibility of fusion power.

It would cost many billions of dollars, the potential rewards are unclear—and the money could be better spent researching threats such as climate change and emerging viruses

An excess of events spotted in the XENON1T experiment could be signs of solar axions or weird, new properties of neutrinos, but not dark matter itself.

Cold atoms can form crystals as a result of the Pauli exclusion principle.

Before there were animals, bacteria or even DNA on Earth, self-replicating molecules were slowly evolving their way from simple matter to life beneath a constant shower of energetic particles from space. In a new paper, a Stanford professor and a former post-doctoral scholar speculate that this interaction between ancient proto-organisms and cosmic rays may be responsible for a crucial structural preference, called chirality, in biological molecules. If their idea is correct, it suggests that all life throughout the universe could share the same chiral preference.

Quantum entanglement – that strange but potentially hugely useful quantum phenomenon where two particles are inextricably linked across space and time – could play a major role in future radar technology.

Stars, galaxies, planets, pretty much everything that makes up our everyday lives owes its existence to a cosmic quirk. The nature of this quirk, which allowed matter to dominate the Universe at the expense of antimatter, remains a mystery. Now, results from an experiment in Japan could help researchers solve the puzzle - one of the biggest in science.
