The webinar is directly linked with a special issue of Plasma Physics and Controlled Fusion on Advances in the Physics Basis of Negative Triangularity Tokamaks; featuring contributions from all of the speakers, and many more papers from the leading groups researching this fascinating topic. In recent years the fusion community has begun [...]

More than a decade following the discovery of the Higgs boson at the CERN particle-physics lab near Geneva in 2012, high-energy physics stands at a crossroads. While the Large Hadron Collider (LHC) is currently undergoing a major £1.1bn upgrade towards a High-Luminosity LHC (HL-LHC), the question facing particle physicists is [...]

One of the brightest stars in the night sky, Betelgeuse, may not be on the brink of exploding as a supernova, according to a new study of the star's brightening and dimming. Instead, recent research shows that the observed pulsing of the starlight is probably caused by an unseen companion [...]

A new experiment to determine whether or not gravity is affected by the act of measurement has been proposed by theoretical physicists in the UK, India and the Netherlands. The experiment is similar to one outlined by the same group in 2017 to test whether or not two masses could [...]

In this episode of Physics World Stories, host Andrew Glester shepherds you through the fascinating world of crowd dynamics. While gazing at a flock of sheep or meandering through a busy street, you may not immediately think of the physics at play – but there is much more than you [...]

Once upon a time, a man took a fast rocket to a faraway planet. He soon missed his home world and took a fast rocket back. His twin sister, a physicist, was heartbroken, saying that they were no longer twins and that her sibling was now younger than she due [...]

A bifocal lens that can adjust the relative intensity of its two focal points using an applied electric field has been developed by Fan Fan and colleagues at China’s Hunan University. The lens features a bilayer structure made of liquid crystal materials. Each layer responds differently to the applied electric [...]

New findings using data from NASA's IXPE (Imaging X-ray Polarimetry Explorer) mission offer unprecedented insight into the shape and nature of a structure important to black holes called a corona. The findings are published in The Astrophysical Journal. [...]

A quasar is the extremely bright core of a galaxy that hosts an active supermassive black hole at its center. As the black hole draws in surrounding gas and dust, it blasts out an enormous amount of energy, making quasars some of the brightest objects in the universe. Quasars have [...]

A newly discovered star could challenge some models of how stars evolve and the way they produce elements as they age. [...]

The quasars appear to have few cosmic neighbors, raising questions about how they first emerged more than 13 billion years ago. A quasar is the extremely bright core of a galaxy that hosts an active supermassive black hole at its center. As the black hole draws in surrounding gas and dust, [...]

Associate professor of physics Riccardo Comin never stops seeking uncharted territory. Riccardo Comin says the best part of his job as a physics professor and exotic materials researcher is when his students come into his office to tell him they have new, interesting data. “It’s that moment of discovery, that moment of [...]
