A Catalog of 12,766 Carbon-enhanced Metal-poor Stars from LAMOST Data Release 8
The Astrophysical Journal Supplement SeriesMetal-poor stars are a rare and ancient type of star; carbon-enhanced metal-poor (CEMP) stars are a subset of these celestial bodies that show an enrichment of carbon relative to iron.

Autoactive MtDMI1 Reprogrammes Immunity and Development in Tomato via Ethylene Signalling
Plant Biotechnology Journal, Volume 24, Issue 5, Page 2861-2875, May 2026.ABSTRACT The Common Symbiosis Signalling Pathway (CSSP) underpins interactions between plants and microbes, yet its potential for crop improvement remains underexplored. Here, we investigated the gain‐of‐function mutant SPD1 (MtDMI1S760N), which constitutively activates the symbiotic signalling pathway in Medicago truncatula, by expressing it in tomato

How plausible are the proposed formation scenarios of CEMP-
, 2016 CEMP-r/s stars are metal-poor stars with enhanced abundances of carbon and heavy elements associated with the slow and rapid neutron-capture process (s- and r-elements, respectively).

Tracing the origin of neutron-capture elements in the metalpoor star HE 1244-3036 [PDF]
EPJ Web of ConferencesWe present results from a detailed abundance analysis of a star HE 1244-3036, based on a high resolution (R ∼ 50000) SUBARU/HDS spectrum. The wavelength coverage is from 3510 to 5310 Å. Our estimated metallicity [Fe/H] ∼ −2.5 and carbon abundance ([C/Fe]

Ground‐truthing of satellite imagery to assess seabird colony size: A test using Adélie penguins
Remote Sensing in Ecology and Conservation, Volume 12, Issue 2, Page 305-317, April 2026.Adélie penguin colony size can be estimated from space using very high‐resolution (VHR; 0.3–0.6 m resolution) satellite imagery due to the contrast between their guano stain and the surrounding terrain. Our study assessed the utility of VHR imagery for making indirect assessments of changes in colony size.

Spatial Resolution Impact Assessment for Long‐Term Population Monitoring of Adélie Penguin Guano
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.Adélie penguins (Pygoscelis adeliae) are key indicators of the Antarctic ecosystem, and remotely sensed guano stains offer an efficient means of estimating breeding abundance. Landsat medium‐resolution (MR) imagery enables long‐term monitoring through its archive.

Elemental abundances and classification of CEMP stars
, 2012 We present a detailed study of Carbon-Enhanced Metal-Poor (CEMP) stars, based on high-resolution spectroscopic observations of a sample of 18 stars. The stellar spectra for this sample were obtained at the 4.2m William Herschel Telescope (WHT) in 2001 and 2002, using the Utrecht Echelle Spectrograph (UES), at a resolving power R ~52000 and S/N ~ 40 ...

Journal of Integrative Plant Biology, Volume 68, Issue 3, Page 587-606, March 2026.Under heat stress, GENOMES UNCOUPLED1 (GUN1) is crucial for the formation of functional chloroplasts in seedlings under heat stress. Without GUN1, chloroplast development fails and seedlings fail to turn green. Therefore, GUN1 helps relay heat‐related cues to maintain chloroplast biogenesis and support thermotolerance during early growth.
