Cutting a photon in two creates an infinite swarm of particles By definition, elementary particles can't be broken into smaller pieces. But in a new theoretical study published in Physical Review Letters, Johannes Skaar and colleagues have revealed what would happen if you tried anyway for a single photon. The answer is deeply strange: attempting to cut a photo...

The Nobel in Physics goes to John Clarke, Michel H. Devoret and John M. Martinis concerning experiments with an electrical circuit in which they demonstrated both quantum mechanical tunnelling and quantised energy levels in a system big enough to be held in the hand.
Includes a lecturette which starts 4 minutes into in the video.

Laser light made into a supersolid for the first time A small international team of nanotechnologists, engineers and physicists has developed a way to force laser light into becoming a supersolid. Their paper is published in the journal Nature. The editors at Nature have published a Research Briefing in the same issue summarizing the work.

Study claims all observables in nature can be measured with a single constant: The second A group of Brazilian researchers has presented an innovative proposal to resolve a decades-old debate among theoretical physicists: How many fundamental constants are needed to describe the observable universe? Here, the term "fundamental constants" refers to the basic standards needed to measure ev...

Particle that only has mass when moving in one direction observed for first time For the first time, scientists have observed a collection of particles, also known as a quasiparticle, that's massless when moving one direction but has mass in the other direction. The quasiparticle, called a semi-Dirac fermion, was first theorized 16 years ago, but was only recently spotted inside...

ATLAS releases first open data from heavy-ion collisions! Today’s release is the highest energy heavy-ion collision data ever made publicly available and is the first LHC Run 2 heavy-ion open dataset. Researchers worldwide can now explore over four terabytes of open data – comprising 221 million collision events – unlocking new opportunities for scientific discussions.

ATLAS observes top quarks in lead-lead collisions The ATLAS Collaboration at CERN has observed top-quark pair production in lead-lead ion collisions, marking the first observation of this process in nucleus-nucleus interactions. This result represents a significant step forward in heavy-ion physics, paving the way for new measurements of the quark-...
