Production of antibacterial compounds by a Steely hybrid polyketide synthase in Dictyostelium

open access: yesFEBS Open Bio, Volume 16, Issue 1, Page 68-78, January 2026.
By selecting appropriate production species under optimised culture conditions, new chlorinated dibenzofuran compounds, which previously could not be analysed in sufficient quantities, were identified from cellular slime mould fruiting bodies. The strong antibacterial activity exhibited by these compounds suggests a link to the ecological function of ...

Initial follow‐up of mechanical QC tests for RapidArc Dynamic (RAD)

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Background RapidArc Dynamic (RAD) is a new solution for delivery of radiotherapy introduced by Varian. RAD blends Volumetric Modulated Arc Therapy (VMAT) and Intensity‐Modulated Radiation Therapy (IMRT) by pausing gantry rotation at predefined positions and adds a degree of freedom: a dynamic collimator.

Two‐Dimensional Alloying at the Iron‐Copper Interface in Steel Driven by Magnetic Friedel Oscillations

open access: yesAdvanced Science, Volume 13, Issue 3, 14 January 2026.
The interlayer magnetic couplings (left) and the changes of atomic‐layer‐averaged electron density (right) for Fe and Cu sides near the sharp and diffuse Fe/Cu (001) interfaces reveal that magnetic Friedel oscillations at Fe/Cu interfaces in steel drive atomic‐scale 2D alloying, resolving the long‐standing paradox of high Fe content in Cu precipitates.
