Space-based photometry reveals regular high-frequency patterns in many young Scuti stars. These pulsations provide a powerful means of inferring stellar properties, particularly ages, for young Scuti stars for which traditional age-dating methods are ...

(pre)possessed: an erasure sequence [PDF]
, 2023 ‘(pre)possessed’ is a sequence of six erasure poems created using found text. The work explores the concept of hidden messages as a form of possession, where apparently unbiased newspaper coverage and banal magazine columns contain the seeds of other ...

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein
FEBS Letters, EarlyView.Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.

Metastatic niche shaped by host factors influences disseminated cancer cell fate
FEBS Letters, EarlyView.Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Discovery of Metal-poor and Distant Pre–Main Sequence Candidates in WLM with JWST
The Astrophysical Journal LettersWe present the discovery of 12 metal-poor and distant pre–main sequence (PMS) candidates in the dwarf irregular galaxy Wolf–Lundmark–Melotte ∼968 kpc away, at a present-day metallicity of [Fe/H] ∼ –0.9.

FEBS Letters, EarlyView.Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.

Does Metallicity Affect the Protoplanetary Disk Fraction? Answers from the Outer Milky Way
The Astrophysical JournalThe role of metallicity in shaping protoplanetary disk evolution remains poorly comprehended. This study analyzes the disk fraction of 10 young (0.9–2.1 Myr) and low-metallicity (0.34–0.83 Z _⊙ ) clusters located in the outer Milky Way with ...

Molecular Oncology, EarlyView.In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

Effect of Time-varying X-Ray Emission from Stellar Flares on the Ionization of Protoplanetary Disks
The Astrophysical JournalX-rays have significant impacts on cold, weakly ionized protoplanetary disks by increasing the ionization rate and driving chemical reactions. Stellar flares are explosions that emit intense X-rays and are the unique source of hard X-rays with an energy ...

The Power of Asteroseismology for Early Stellar Evolution
Frontiers in Astronomy and Space Sciences, 2019 Stars are the building blocks of planetary systems, clusters, associations, and galaxies. The evolution of stars is driven by physical processes in their interiors making theory of stellar interior structure and evolution an important ingredient of ...
