Plant Biology, Volume 28, Issue 4, Page 1043-1051, June 2026.Potassium silicate can decrease the uptake of sodium (Na+) into wheat cells by affecting the Na+ uptake channels and increasing ion homeostasis. Abstract Salinity causes negative impacts on crops. We investigated the effect of potassium silicate (K2SiO3) on the cytosolic uptake of sodium, [Na+]cyt, in mesophyll protoplasts of wheat cultivars differing ...

Psychophysiology, Volume 63, Issue 6, June 2026.ABSTRACT Spontaneous pupil fluctuations (SPFs) during rest provide a non‐invasive, low‐cost index of central arousal dynamics, independent of cognitive task demands. These features position SPFs as promising markers for baseline neurophysiological activity in both basic and translational research. This review synthesizes current evidence on the resting‐

Quantifying the Contamination of TESS Ecliptic-plane Light Curves by Minor Planets
The Astronomical JournalThough missions devoted to time series photometry focus primarily on targets far beyond the solar system, their observations can be contaminated by foreground minor planets, especially near the ecliptic plane, where solar system objects are most ...

Transit and secondary eclipse photometry in the near-infrared
, 2007 Near-infrared photometry of transiting extrasolar planets can be of great scientific value. It is however not straightforward to reach the necessary millimagnitude precision. Here we report on our attempts to observe transits and secondary eclipses of several extrasolar planets at 2.2 micron.

GJ 238 b: A 0.57 Earth Radius Planet Orbiting an M2.5 Dwarf Star at 15.2 pc
The Astronomical JournalWe report the discovery of the transiting planet GJ 238 b, with a radius of 0.566 ± 0.014 R _⊕ (1.064 ± 0.026 times the radius of Mars) and an orbital period of 1.74 days. The transit signal was detected by the TESS mission and designated TOI-486.01. The

Relative photometry of transiting exoplanet CoRoT-Exo-2b
, 2009 Relative CCD photometry of the extrasolar planet COROT-Exo-2b transiting in front of its parent star was carried out at the Astronomical and Geophysical Observatory of Comenius University at Modra (AGO). Physical and orbital parameters were determined and compared with the previous published data.
