Proton therapy on an upward trajectory while FLASH treatment schemes get ready to shine

While proton therapy has well and truly arrived as a mainstream treatment option in radiation oncology – there are currently 42 operational proton facilities in the US and a further 13 centres under construction – it’s evident that the clinical innovation is only just getting started when it comes to at-scale deployment of protons for… Continue reading Proton therapy on an upward trajectory while FLASH treatment schemes get ready to shine

Multi-eye-component imaging could help diagnose ocular disease

How it works: the noninvasive imaging technique combines acoustic radiation force and optical coherence tomography to produce 3D elastic wave speed maps of multiple eye components simultaneously. Left: cross-sectional image of a wave speed map of the anterior segment of the eyeball depicting different eye components: lens (L), iris (I), cornea (C), and sclera (S).… Continue reading Multi-eye-component imaging could help diagnose ocular disease

Quantum-computing protocol avoids targeting individual atoms in an array

Quantum bits (qubits) based on cold atoms are increasingly attractive candidates for quantum computing. However, targeting single atoms in an array with lasers to manipulate them individually for processing quantum information remains a challenge. Now,  Hannes Pichler at Austria’s University of Innsbruck and Francesco Cesa, who was visiting from Italy’s University of Trieste, have designed… Continue reading Quantum-computing protocol avoids targeting individual atoms in an array

Superconductivity ‘damaged’ as researchers look to move on from retractions

Update 07/11/2023: The Lu-N-H paper (Nature 615 244) has since been retracted by the journal.   “I’m going to introduce a new material for the first time.” So said the condensed-matter physicist Ranga Dias to a packed conference room at the March meeting of the American Physical Society in Las Vegas earlier this year. The… Continue reading Superconductivity ‘damaged’ as researchers look to move on from retractions

Quantum algorithms make clever use of noisy hardware

While quantum computers show great promise for the future, today’s processors are small and noisy – and this makes it very difficult to do meaningful quantum calculations right now. To address this problem, researchers are developing clever quantum algorithms that make the most out of the hardware that is available today. Some of those algorithms… Continue reading Quantum algorithms make clever use of noisy hardware
