JWST-TST High Contrast: JWST/NIRCam Observations of the Young Giant Planet β Pic b

The Astronomical Journal
We present the first JWST/NIRCam observations of the directly imaged gas giant exoplanet β Pic b. Observations in six filters using NIRCam's round coronagraphic masks provide a high-signal-to-noise-ratio detection of β Pic b and the archetypal debris ...

Out in the cold? A review of Early Middle Palaeolithic settlements in northern Central Europe, age data and geological preconditions for site formation and preservation

Boreas, EarlyView.
The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the

The Cold Debris Disk Surveys. I. Host Star Properties

The Astronomical Journal
We describe the dynamical, photometric, and spectroscopic data available for stars targeted by Spitzer and Herschel to search for cold circumstellar dust emission from debris disks, a collection that we name the Cold Debris Disk Surveys (CDDS).

Coastal evolution, environmental change and carbon storage in the Thung Prong Thong Mangrove, eastern Gulf of Thailand

Boreas, EarlyView.
Palaeoenvironmental records along the eastern coast of Thailand remain sparse, with only a few studies attempting to reconstruct past climatic and environmental conditions. However, additional palaeoenvironmental, palaeoclimatic and sea‐level records are needed to improve our understanding of coastal evolution and local environmental changes.

Searching for Planets Orbiting Vega with the James Webb Space Telescope

The Astronomical Journal
The most prominent of the IRAS debris disk systems, α Lyrae (Vega), at a distance of 7.7 pc, has been observed by both the NIRCam and MIRI instruments on the James Webb Space Telescope.

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

Boreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Intraocular Metastasis: Differential Diagnosis and Management

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Intraocular metastases represent the most common type of malignant intraocular tumour in adults. These commonly affect the choroid but can also involve the iris, ciliary body, retina, vitreous, optic disc or lens. Breast and lung cancer are the most common origins of intraocular metastases.

Hcfc1 and Ogt Mediate Zebrafish CNS Regeneration Through Hippo/Yap Signalling

Cell Proliferation, EarlyView.
This work identifies Hcfc1 and Ogt as key regulators of zebrafish CNS regeneration through modulation of Hippo/Yap signalling. Loss of Hcfc1 or Ogt activity inhibition impairs regeneration, which is restored by Yap overexpression, revealing a new regulatory axis that enhances CNS regenerative capacity.

AMSC‐sEVs Ameliorated Crohn's Disease by Inhibiting Macrophage‐Myofibroblast Transition Through the Delivery of MFGE8

Cell Proliferation, EarlyView.
Our study demonstrated that TGF‐β1 activated MAPK signalling pathway and promoted the MMT and secretion of CCL17 under CD‐associated intestinal inflammatory conditions. AMSC‐sEVs can deliver MFGE8, which inhibits MMT and CCL17‐mediated Treg recruitment by suppressing the MAPK signalling pathway, thereby alleviating intestinal fibrosis.

The technical and practical implementation of fundus photography in equids

Equine Veterinary Education, EarlyView.
Summary Background Fundus photography is an important diagnostic tool in human and veterinary medicine. Advances in research are increasing its accessibility in human medicine. However, there is a lack of studies on modern fundus photography in animals, particularly in horses. Objectives To assess the use of a portable fundus camera developed for human
