Radiobiology studies of gold nanoparticle‐enhanced radiosensitization in proton therapy

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Approximately 50%$\%$ of newly diagnosed cancer patients worldwide receive radiotherapy, most commonly with X‐rays. Proton therapy has emerged as a promising alternative, offering complementary advantages over conventional X‐rays due to its highly localized energy deposition at the Bragg peak, thereby reducing radiation exposure to ...

Cybianthus anthuriophyllus (Primulaceae), a new record for the flora of Colombia: distribution modeling and conservation assessment

Nordic Journal of Botany, Volume 2026, Issue 8, August 2026.
Cybianthus anthuriophyllus (Primulaceae) was previously known from eastern Ecuador and northern Peru. Here we document the first confirmed occurrences of this species in Colombia and develop a distribution model based on collections from the Andean–Amazonian foothills of Caquetá, Cauca, and Putumayo departments, in order to clarify its conservation ...

Programmable Inter‐Droplet Communication by Polymer‐Gated Ion Transport Through Nanopore Lattices

Small Science, Volume 6, Issue 8, August 2026.
Laser‐written polyelectrolyte barriers were applied for regulating imbibition and ion transport through silica mesopores between droplet compartments. Specific imbibition sequences and precipitation readouts indicated cation‐selective transport across the barriers. Depending on salt identity, barrier, and experimental parameters, ionic transport ranged

Ground‐Based Solar Radio Observations From the Mexican e‐Callisto Stations During the May 2024 Extreme Space Weather Events

Space Weather, Volume 24, Issue 8, August 2026.
Abstract The period from 1 to 14 May 2024 was marked by some of the most intense solar activity of Solar Cycle 25, including multiple X‐class flares, fast coronal mass ejections (CMEs), and diverse solar radio emissions. We present observations from the Mexican e‐Callisto network (REC‐Mx), including long‐duration continuum emissions (CTMs), Type II ...

Progerin Hinders Autophagy Flux at Its Final Stages in Hutchinson‐Gilford Progeria Syndrome Cells, Preventing Its Own Autophagic Degradation

Aging Cell, Volume 25, Issue 8, August 2026.
We demonstrated that progerin induces the formation of autophagosomes but impairs their maturation and subsequent fusion with lysosomes. Progerin impedes proper autophagy flux, thus preventing its own autophagic degradation. Selinexor treatment improved both autophagosome maturation and autophagosome‐lysosome fusion, which ultimately led to effective ...
