Mission Design and Early Navigation Operations for the Lunar Trailblazer Mission

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Lunar Trailblazer is a smallsat mission launched on 27 February 2025 as a secondary payload with the Intuitive Machines IM‐2 mission. After insertion into a near‐polar circular orbit around the Moon, the mission's goal was to search and characterize lunar water, primarily looking for ice in permanently shadowed craters and water bound in ...

Extracting starspot structures from exoplanet transit photometry

Astronomy & Astrophysics
Context . Future space-based transit photometry can provide empirical comparisons of solar and stellar spot structures with high precision. Spot transit mapping provides a way to directly observe and characterize the location, size, intensity, and evolution of starspots to infer stellar rotation rates and ...

X‐ray fluorescence microscopy exposure estimates using a single excitation energy

Journal of Synchrotron Radiation, Volume 33, Issue 4, Page 1074-1084, July 2026.
We present calculations on the number of illuminating photons per pixel required for elemental detection using X‐ray fluorescence, even with far‐from‐threshold excitation.Scanning fluorescence X‐ray microscopy is widely used for quantitative mapping of elemental concentrations, including in studies of essential but low‐concentration metals in cells ...

Transcriptional Response to Chronic Long‐Access Fentanyl Self‐Administration in Rat Habenula and Amygdala

Addiction Biology, Volume 31, Issue 7, July 2026.
Chronic intravenous long‐access fentanyl self‐administration in rats produced transcriptional remodeling in the habenula and amygdala. Bulk RNA‐sequencing identified 453 habenula and 3,041 amygdala differentially expressed genes, revealing upregulation of synaptic process and ionic conductance genes in habenula, upregulation of metabolic and vesicular ...

GJ 238 b: A 0.57 Earth Radius Planet Orbiting an M2.5 Dwarf Star at 15.2 pc

The Astronomical Journal
We 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

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.

Pharmacological treatment with a GABA(A) receptor modulator and a selective serotonin reuptake inhibitor as a mitigation strategy against aircraft noise‐induced cardiovascular and neuronal damage

British Journal of Pharmacology, Volume 183, Issue 13, Page 3762-3779, July 2026.
Abstract Background and Purpose Noise pollution, particularly by aircraft, is a significant risk factor for cardiovascular disease. Aircraft noise activates stress response pathways in the brain, via the amygdala, the sympathetic nervous system and the hypothalamic–pituitary–adrenal axis.

LHS 475 b: A Potential Venus Analog Orbiting a Nearby M Dwarf

The Astronomical Journal
Based on photometric observations by TESS, we present the discovery of a potential Venus analog transiting LHS 475, an M3 dwarf located 12.5 pc from the Sun. The mass of the star is 0.274 ± 0.015 M _☉ .

Key metabolites secreted by Chlorella vulgaris alleviate salt stress in soybean seedlings

Journal of Integrative Plant Biology, Volume 68, Issue 7, Page 2018-2036, July 2026.
Chlorella vulgaris secretes exosome‐derived linolenic acid and inosine, which alleviate salt stress and enhance salt tolerance in soybean seedlings by activating stress‐responsive signaling networks. ABSTRACT Soil salinization is a major abiotic stress factor that reduces soybean production.

Quantifying the Contamination of TESS Ecliptic-plane Light Curves by Minor Planets

The Astronomical Journal
Though 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 ...
