Physicists have designed the first device to create particles with charged negative mass. The breakthrough could lead to an entirely new way to generate laser light using only a tiny amount of energy.

Scientists have captured the first ever image of a phenomenon which Albert Einstein once described as "spooky action at a distance". The photo shows a strong form of quantum entanglement, where two particles interact and share their physical states for an instant. It occurs no matter how great the distance between the particles is.

Up to today, most experiments have tested entanglement over spatial gaps. The assumption is that the 'nonlocal' part of quantum nonlocality refers to the entanglement of properties across space. But what if entanglement also occurs across time? Is there such a thing as temporal nonlocality? The answer, as it turns out, is yes.

Every type of atom in the universe has a unique fingerprint: It only absorbs or emits light at the particular energies that match the allowed orbits of its electrons. That fingerprint enables scientists to identify an atom wherever it is found. A hydrogen atom in outer space absorbs light at the same energies as one on Earth.

Now that they’ve identified the Higgs boson, scientists at the Large Hadron Collider have set their sights on an even more elusive target. All around us is dark matter and dark energy—the invisible stuff that binds the galaxy together, but which no one has been able to directly detect. “We know for sure there’s a dark world, and there’s more energy in it than there is in ours,” said LianTao Wang, a University of Chicago professor of physics who studies how to find signals in large particle accelerators like the LHC.

Dark matter has long frustrated researchers. It seems to make up most of our universe, yet it barely interacts with that universe. And despite a plethora of active experiments hunting for dark matter, so far they’ve all turned up empty. That has some researchers turning to the next best thing: other dark particles. Our world of normal matter has lots of different particles, so perhaps there’s a whole dark world of particles as well. To be clear, no one’s found these either, and there’s even less proof for their existence.

A strange glow coming from the Milky Way’s center was thought to be due to ordinary pulsars. But a new look at a years-old study shows that dark matter might still be responsible.

Murray Gell-Mann, the Nobel-winning physicist who brought order to the universe by helping discover and classify subatomic particles, has died. He was 89. Gell-Mann died on Friday at his home in Santa Fe, New Mexico. His death was confirmed by the Santa Fe Institute, where he held the title of distinguished fellow, and the California Institute of Technology, where he taught for decades. The cause was not disclosed.

A lab-made black hole that traps sound, not light, emits radiation at a certain temperature, as Stephen Hawking first predicted.

The European Organization for Nuclear Research, better known as CERN, and also known as home of the Large Hadron Collider, has announced plans to migrate away from Microsoft products and on to open-source solutions where possible. Why? Increases in Microsoft license fees. Microsoft recently revoked the organisations status as an academic institution, instead pricing access to its services on users. This bumps the cost of various software licenses 10x, which is just too much for CERN's budget.

Two theoretical physicists at the University of California, Davis, have a new candidate for dark matter, and a possible way to detect it. They presented their work June 6 at the Planck 2019 conference in Granada, Spain, and it has been submitted for publication.  Dark matter is thought to make up just over a quarter of our universe, with most of the rest being even-more mysterious dark energy. It cannot be seen directly, but dark matter’s presence can be detected because its gravity determines the shape of distant galaxies and other objects. 

Heisenberg's famous Uncertainty Principle is put to the test to see if things really are uncertain in the quantum world.

Scientists have created a long-sought particle in the lab by hitting a crystal lattice with photons.

The Standard Model is a kind of periodic table of the elements for particle physics. But instead of listing the chemical elements, it lists the fundamental particles that make up the atoms that make up the chemical elements, along with any other particles that cannot be broken down into any smaller pieces.

On 3 June this year, the Large Hadron Collider at CERN began delivering particle collisions at an energy 63% higher than previously acheived. This week in Vienna, first physics results were presented. Here are some highlights.

The NOvA detector has seen its first neutrino oscillations.

Researchers pushing the Large Hadron Collider to its limits say engineering difficulties will cut short the amount of physics data gathered this year.

Physicists search for deviations from normal gravity

Accelerating positrons with plasma is a step toward smaller, cheaper particle colliders.

Subatomic particles have been found that appear to defy the Standard Model of particle physics. The team working at Cern's Large Hadron Collider have found evidence of leptons decaying at different rates, which could possibly point to some undiscovered forces. Publishing their findings in the journal Physical Review Letters, the team from the University of Maryland had been searching for conditions and behaviours that do not fit with the Standard Model.

First results from collisions of three-particle ions with gold nuclei reveal clear-cut evidence of primordial soup's signature particle flow.

The neutrino and its antimatter cousin, the antineutrino, are the tiniest subatomic particles known to science. These particles are byproducts of nuclear reactions within stars (including our sun), supernovae, black holes and human-made nuclear reactors. They also result from radioactive decay processes deep within the Earth, where radioactive heat and the heat left over from the planet's formation fuels plate tectonics, volcanoes and Earth's magnetic field.

A leftover glow unlike any other — of neutrinos — has finally been seen.

The LHC and the Belle experiment have found particle decay patterns that violate the Standard Model of particle physics

As new data continue to be collected at CERN, another look at some of the straws in the wind, otherwise known as “hints of new physics”, that might develop into exciting breakthroughs

An emerging theory takes principles from quantum physics and applies them to psychology.

Researchers at the National Institute of Standards and Technology (NIST) have “teleported” or transferred quantum information carried in light particles over 100 kilometers (km) of optical fiber, four times farther than the previous record.

It’s been more than three years since we’ve found the Higgs boson. So how does it give particles mass?

The most powerful accelerator in the world found the Higgs, but might not find anything else. What should come next?

Machines that ‘surf’ particles on electric fields could reach high energies at a lower price.

A team of scientists have made what may turn out to be the most important discovery in history – how the universe came into being from nothing. The colossal question has troubled religions, philosophers and scientists since the dawn of time but now a Canadian team believe they have solved the riddle. And the findings are so conclusive they even challenge the need for religion, or at least an omnipotent creator – the basis of all world religions.

Other universes might be bumping into ours, and these bumps are leaving their mark.

The kind of research being conducted at CERN is a reminder of what we can accomplish, together, even amid the darkest of times, says physicist Marcelo Gleiser.
