A Core Head, Neck, and Neuroanatomy Syllabus for Physical Therapy Student Education

Clinical Anatomy, Volume 39, Issue 4, Page 436-460, May 2026.
ABSTRACT Head, neck, and neuroanatomy are essential components of physical therapy education due to their broad clinical applications. Detailed syllabi exist for medical students, yet none have been developed for physical therapy. This study aimed to produce an International Federation of Associations of Anatomists core head, neck, and neuroanatomy ...

Sunspot Number Variations [PDF]

In this activity students find the patterns that emerge when sunspot numbers are plotted over a period of time. Students learn about sunspot variations and the solar cycle, and are able to predict future solar minimums and solar maximums.

A High‐Efficiency Multivariable TEC‐SOFTS Model for Ionospheric TEC Prediction: Validation Over China Area During Low and High Solar Activity Periods

Space Weather, Volume 24, Issue 5, May 2026.
Abstract The ionospheric Total Electron Content (TEC) is a key parameter for characterizing the ionospheric properties. In this study, an efficient multivariable time series prediction model, TEC‐Series Core Fusion and efficient multivariable time series (TEC‐SOFTS), was constructed by combining multiple geomagnetic and solar activity indices ...

The heliospheric Hale cycle over the last 300 years and its implications for a “lost” late 18th century solar cycle

Journal of Space Weather and Space Climate, 2015
A Hale cycle, one complete magnetic cycle of the Sun, spans two complete Schwabe cycles (also referred to as sunspot and, more generally, solar cycles). The approximately 22-year Hale cycle is seen in magnetic polarities of both sunspots and polar fields,

Long-term Solar Irradiance Variability: 1984-1989 Observations [PDF]

, 1990
Long-term variability in the total solar irradiance has been observed in the Earth Radiation Budget Experiment (ERBE) solar monitor measurements. The monitors have been used to measure the irradiance from the Earth Radiation Budget Satellite (ERBS) and ...

Multi‐Decadal Trends in the Low Latitude foF2 Driven by Secular Magnetic Variations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Long‐term ionospheric trends have been widely studied, but their origin and magnitude remain subjects of debate. This study quantifies the linear trend in the F2‐region critical frequency (foF2) and its local time dependence using observations from eight low‐latitude ionosonde stations.

Decellularized Aged Bruch's Membrane Confers Unique Biochemical Cues to Retinal Pigment Epithelium for In Vitro Modeling of Age‐Related Macular Degeneration

Aging Cell, Volume 25, Issue 5, May 2026.
A Bruchs membrane (BrM) mimic based on aged decellularized BrM was developed and differentially expressed proteins in aged dECM‐BrM that may provide specific biochemical cues fundamental to model AMD in vitro were identified. RPE culture on aged dECM‐BrM developed certain AMD‐like features including reduced TEER and expression of drusen components ...

Retinal Pigment Epitheliopathy due to Sub‐Optimal Recycling of Vitamin A (RESORVA): A Novel RDH11 ‐Related Phenotype

Clinical Genetics, Volume 109, Issue 5, Page 972-977, May 2026.
RDH11 is a minor isoenzyme that catalyses the oxidation of 11‐cis‐retinol to 11‐cis‐retinal in the retinal pigment epithelium, alongside RDH5 and RDH10. Biallelic null variants in RDH11 lead to upregulation of RDH5 and RDH10 (transcriptional adaptation), maintaining 11‐cis‐retinal bioavailability, but still causing Retinal Pigment Epitheliopathy due to

Can the International Reference Ionosphere Model Predict Long‐Term Trends in the Ionosphere?

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The International Reference Ionosphere (IRI) model can partially reproduce ionospheric long‐term trends (LTTs), although not intentionally, provided that an appropriate effective ionospheric index is used. We evaluate how model predictions driven by a solar activity proxy (R12) and by an effective ionospheric proxy (IG12) can reproduce the ...

Polar Filaments Capture High-latitude Solar Poloidal Field Interactions and Can Foretell the Future Sunspot Cycle Amplitude before Polar Field Precursors

The Astrophysical Journal Letters
Polar fields at the minimum of a sunspot cycle—which are a manifestation of the radial component of the Sun’s poloidal field—are deemed to be the best indicator of the strength of the toroidal component and hence, the amplitude of the future sunspot ...
