Physics news
New ALICE measurements shed light on the dynamics of charm and beauty particles in quark-gluon plasmaWhen two lead ions collide at the Large Hadron Collider (LHC), they produce an extremely hot and dense state of matter in which quarks and gluons are not confined inside composite particles called hadrons. This fireball of particlesāknown as quarkāgluon plasma and believed to have filled the universe in the first few millionths of a second after the Big Bangāexpands and cools down rapidly. The quarks and gluons then transform back into hadrons, which fly out of the collision zone towards particle detectors. | |
Q&A: Bringing virtual reality to nuclear and particle physicsVirtual reality, or VR, is not just for fun-filled video games and other visual entertainment. This technology, involving a computer-generated environment with objects that seem real, has found many scientific and educational applications as well. | |
Researchers turn a small photonic chip into a functional temperature sensorSimilar to electronics, photonic circuits can be miniaturized onto a chip, leading to a so-called photonic integrated circuit (PIC). Although these developments are more recent than for electronics, this field is rapidly evolving. One of the main issues, however, is to turn such a PIC into a functional device. This requires optical packaging and coupling strategies to bring light into and get light out of the PIC. |
Earth news

Five major outcomes from the latest UN climate summitThe latest UN climate summit, COP28, was always going to be controversial. It was held in a state whose economy is heavily dependent on oil and gasāthe United Arab Emirates. The summit president, Sultan Al Jaber, remains head of the Abu Dhabi National Oil Company and recently declared the UAE would double oil and gas output this decade. | |
Opinion: COP28 agreement on adapting to climate change kicks the real challenge down the roadCOP28 concluded late on Wednesday morning to a mixed reaction. The Dubai agreement extracted a promise from nearly 200 countries to transition away from fossil fuels, but it leaves many questions unanswered when it comes to keeping global average temperatures from warming by more than 1.5Ā°C. The world is rapidly running out of time to limit temperatures to this levelāa crucial threshold for many communities living in low-lying islands and delicate ecosystems such as coral reefs. | |
How the world's first deal to ditch fossil fuels was forged at COP28It was an improbable scene in Dubai as a top oil executive basked in a standing ovation from hundreds of diplomats tasked with fighting climate change. Sultan Al Jaber, head of the United Arab Emirates' state-owned oil company, had just presided over the two-week COP28 summit that led to the world's first agreement to move away from fossil fuels. There were tears, hugs, and claps on the back as exhausted delegates celebrated a milestone in the battle against global warming. | |
