Changes in photosynthesis and grazing facilitate growth of a mixotrophic protist under ocean acidification and warming

New Phytologist, Volume 251, Issue 5, Page 2574-2587, September 2026.
Grazing rates of Ochromonas CCMP2951 expressed as carbon obtained per mean cell volume (a) and Caut/het‐photosynthetically fixed carbon divided by carbon obtained through grazing (b) in the four experimental treatments. Summary Mixotrophic protists capable of both photosynthesis and phagotrophy are key members of marine plankton communities.

Application of a low‐cost Geiger–Müller monitoring system for clinical radiation environments

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Low‐cost Geiger–Müller detectors may support clinical radiation monitoring, but their response varies with radiation type and measurement conditions. Purpose To evaluate an Arduino‐based Geiger–Müller monitoring system in representative clinical radiation environments and determine whether condition‐specific calibration reduces ...

Mixing‐Driven Defects and Composition Evolution in Multi‐Material Metal Additive Manufacturing

Advanced Science, Volume 13, Issue 45, 13 August 2026.
Operando synchrotron X‐ray imaging coupled with high‐fidelity multiphysics modeling uncovers how inter‐material mixing reshapes keyhole dynamics and drives distinct pore‐formation pathways in multi‐material laser powder bed fusion (LPBF). Composition‐dependent instabilities trigger defects, whereas rescanning suppresses porosity and homogenizes Cu ...
