Confirmation of an exoplanet using the transit color signature: Kepler-418b, a blended giant planet in a multiplanet system

, 2014
We announce confirmation of Kepler-418b, one of two proposed planets in this system. This is the first confirmation of an exoplanet based primarily on the transit color signature technique.

Hypoxic‐hypocapnic red blood cells in PAGGSM additive solution before and after gamma irradiation show improved metabolism

Vox Sanguinis, EarlyView.
Abstract Background and Objectives Hypoxic/hypocapnic (HH) treatment and storage conditions have been shown to reduce oxidative stress and improve red blood cell (RBC) quality. This study aimed to validate a good manufacturing practice HH RBC product for obtaining the licence for routine use in patients, by comparison with normoxic RBCs both without ...

The Challenge of Wide-Field Transit Surveys: The Case of GSC 01944-02289

, 2005
Wide-field searches for transiting extra-solar giant planets face the difficult challenge of separating true transit events from the numerous false positives caused by isolated or blended eclipsing binary systems.

Hyperaldosteronism in Mice Lacking the Distal Polybasic Tract of the γ‐Subunit of the Epithelial Sodium Channel During Sodium Restriction

Acta Physiologica, Volume 242, Issue 6, June 2026.
ABSTRACT Aims The epithelial sodium channel ENaC consists of the subunits α, β, and γ and is activated at an individual channel level by proteolytic processing. Murine γENaC contains a distal polybasic tract 186RKRK mediating proteolytic ENaC activation by serine proteases in vitro.

Dazzle: Oversampled Image Reconstruction and Difference-imaging Photometry for the Nancy Grace Roman Space Telescope

The Astronomical Journal
We present algorithms and software for constructing high-precision difference images to detect and measure transients, such as microlensing events, in crowded stellar fields using the Nancy Grace Roman Space Telescope.

Benefits of Ground-Based Photometric Follow-Up for Transiting Extrasolar Planets Discovered with Kepler and CoRoT

, 2009
Currently, over forty transiting planets have been discovered by ground-based photometric surveys, and space-based missions like Kepler and CoRoT are expected to detect hundreds more.

Genetic Diversity, Population Structure, and Environmental Influences in Nepeta glomerulosa: Implications for Conservation in the Irano‐Turanian Region

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Nepeta glomerulosa shows moderate genetic diversity with three main clusters and significant admixture, highest in the Alborz Mountains, suggesting it may be the center of origin. High genetic differentiation (Gst = 0.4199) points to limited gene flow and possible self‐pollination, with geographic isolation shaping population structure.

An Oasis in the Brown Dwarf Desert: Confirmation of Two Low-mass Transiting Brown Dwarfs Discovered by TESS

The Astronomical Journal
As the intermediate-mass siblings of stars and planets, brown dwarfs (BDs) are vital to study for a better understanding of how objects change across the planet-to-star mass range.

Constraining exotrojans in hot-Jupiter systems using transit timing variation observations from TESS

Astronomy & Astrophysics
Context. Co-orbital objects, also known as Trojans, are celestial bodies that share a 1:1 mean motion resonance orbit with a planet. Many planets in our Solar System hold Trojans, yet none has been confirmed in exoplanetary systems.

Characterizing the Cool KOIs II. The M Dwarf KOI-254 and its Hot Jupiter

, 2012
We report the confirmation and characterization of a transiting gas giant planet orbiting the M dwarf KOI-254 every 2.455239 days, which was originally discovered by the Kepler mission.
