Critical point drying of brain tissue for X‐ray phase‐contrast imaging

Journal of Synchrotron Radiation, Volume 33, Issue 3, Page 759-768, May 2026.
X‐ray phase contrast tomography can efficiently image brain tissue at subcellular resolution. Critical point drying allows a gentle replacement of interstitial material by air, enhancing X‐ray phase contrast of the ultrastructural features.X‐ray phase‐contrast tomography can efficiently image brain tissue at subcellular resolution.

On the optimization of the geometric pattern for structured illumination based X‐ray phase contrast and dark‐field imaging: a simulation study and its experimental validation

Journal of Synchrotron Radiation, Volume 33, Issue 3, Page 806-817, May 2026.
Single‐mask phase contrast and dark‐field imaging methods offer the great advantage of being simple to implement, translating most of the complexity to the numerical side. In this work, we study the impact of the modulation topology on the image quality retrieved both on numerical simulation and experiments.Phase contrast and dark‐field imaging are ...

Data driven drift correction for complex optical systems

Journal of Synchrotron Radiation, Volume 33, Issue 3, Page 596-603, May 2026.
Time varying Bayesian optimization as a data driven approach for robust drift correction is outlined, and its application for a split and delay x‐ray optical system is illustrated.To exploit the thousand‐fold increase in spectral brightness of modern light sources, increasingly intricate experiments are being conducted that demand extremely precise ...

Plasma Dilution After Myocardial Ischemia–Reperfusion Injury Promotes Cardiac Repair, Heart Performance, and Recovery of Motor Function and Endurance in Old Mice

Aging Cell, Volume 25, Issue 5, May 2026.
Plasma dilution at 24 h after I/R improved cardiac remodeling, function, and the physical performance of old male and female mice, through lowered markers of inflammation, fibrosis, reduction of cardiomyocytes' apoptosis, increase in their cell‐cycle re‐entry, and healthier profile of newly synthesized proteome, including the determinants of Jak/Stat ...

Are physiological oscillations physiological?

The Journal of Physiology, Volume 604, Issue 9, Page 3672-3693, 1 May 2026.
Abstract figure legend Mechanisms and functions of physiological oscillations. Abstract Despite widespread and striking examples of physiological oscillations, their functional role is often unclear. Even glycolysis, the paradigm example of oscillatory biochemistry, has seen questions about its oscillatory function.
