The 2024 Nobel prizes in both physics and chemistry were awarded, for the first time, to scientists who have worked extensively with artificial intelligence (AI). Computer scientist Geoffrey Hinton and physicist John Hopfield shared the 2024 Nobel Prize for Physics. Meanwhile, half of the chemistry prize went to computer scientists [...]

What skills do you use every day in your job? Being sociable, switching topics in an instant and making judgements. Being sociable may sound trivial, but collaboration has been vital in all the roles I have had, especially now that I work in such a large and complex organization. No single person [...]

Researchers at the University of Iowa and University Medical Center Utrecht are working to incorporate volumetric-modulated arc therapy (VMAT) delivery capabilities into the MR-linac. They present the first dosimetric evaluation comparing VMAT and intensity-modulated radiation therapy (IMRT) on the MR-linac in the International Journal of Radiation Oncology, Biology, Physics. “We’ve been [...]

This episode of the Physics World Weekly podcast explores the science and commercial applications of metamaterials with Claire Dancer of the University of Warwick and Alastair Hibbins of the University of Exeter. They lead the UK Metamaterials Network, which brings together people in academia, industry and governmental agencies to support and [...]

A team of scientists based in the US has developed a non-invasive headset device designed to track changes in blood flow and assess a patient’s stroke risk. The device could make it easier to detect early signs of stroke, offering patients and physicians a direct, cost-effective approach to stroke prevention. The [...]

Using the NASA/ESA/CSA James Webb Space Telescope, an international team of astronomers have found new galaxies in the Spiderweb protocluster. Their characteristics shed light on the growth of galaxies in these large cosmic cities, with the finding that gravitational interactions in these dense regions are not as important as previously [...]

I’m pleased to welcome you to Physics World’s coverage supporting the International Year of Quantum Science and Technology (IYQ) in 2025. The IYQ is a worldwide celebration, endorsed by the United Nations (UN), to increase the public’s awareness of quantum science and its applications. The year 2025 was chosen as [...]

A new observation of electron and positron cosmic rays has confirmed the existence of what could be a “cooling break” in the energy spectrum at around 1 TeV, beyond which the particle flux decreases more rapidly. Aside from this break, however, the spectrum is featureless, showing no evidence of an [...]
