Stereotactic ablative radiotherapy can deliver highly focused radiation to metastases (left). The ORIOLE trial showed that this can slow prostate cancer progression (right). (Courtesy: Radiat. Oncol 10.1016/j.adro.2019.10.006 /Phuoc Tran) Stereotactic ablative radiotherapy (SABR) is a popular method for treating small, inoperable tumours in various anatomical sites. This type of radiotherapy delivers highly focused, intense radiation

Tue, Apr 28, 2020 2:00 PM – 3:00 PM BST This webinar will start with some basic nanoindentation theory and focus on its shortcomings with regards to the unique mechanical characteristics of polymers, particularly their strong time-dependence. To overcome this shortcoming, a nanoscale compliment of Dynamic Mechanical Analysis, Bruker’s nanoDMA III presented. This simple method

Safe distance: Urs Schneider demonstrates the remote access checker. (Courtesy: Robert Bosch Hospital/Christoph Schmidt) A system that checks from a safe distance whether someone is displaying symptoms of COVID-19 has been developed by Urs Schneider and colleagues at the Fraunhofer Institute for Manufacturing Engineering and Automation in Stuttgart, Germany. The team’s “access checker” combines infrared

Andrés Castellanos-Gómez is a materials researcher who combines tradition with the cutting edge. His group at the Materials Science Institute of Madrid are interested in complex oxides, which are grown epitaxially on the surface of crystals before being isolated from their substrate by etching. Alongside this long established method, they deploy techniques from the emerging

One of the enduring mysteries of physics is why the universe appears to contain much more matter than antimatter. An important clue has just been unearthed by the T2K experiment in Japan, which found a difference in what happens to muon neutrinos and antineutrinos as they travel through nearly 300 km of solid rock. In this

Particle selector: schematic diagram of the “horn” on J-PARC, which is used to select beams of neutrinos or antineutrinos. (Courtesy: J-PARC) Physicists operating a huge detector in Japan have confirmed previous hints that neutrinos behave differently to their antimatter counterparts. The researchers, who make up the T2K collaboration, point out that it is still too
