Vision at high latitudes: High sensitivity without specific boreal adaptations in photoreception in reindeer (Rangifer tarandus L.)

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The light climate at high latitudes, in particular the extended twilight of winter and the reduced diel variation in light level in midsummer and midwinter, potentially constrains visual function and the synchronisation of temporal organisation in polar species. In this

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.

Cosmic Microwave Background Radiation Anisotropy Induced by Cosmic Strings

, 1994
We report on a current investigation of the anisotropy pattern induced by cosmic strings on the cosmic microwave background radiation (MBR). We have numerically evolved a network of cosmic strings from a redshift of $Z = 100$ to the present and ...

Energy Radiation by Cosmic Superstrings in Brane Inflation

, 2008
The dominant method of energy loss by a loop of cosmic D-strings in models of warped brane inflation is studied. It is shown that the energy loss via Ramond-Ramond field radiation can dominate by many orders of magnitude over the energy radiation via ...

Pollination ecology in the tropical Andes: moving towards a cross‐scale approach

Biological Reviews, EarlyView.
ABSTRACT Plant–pollinator interactions structure ecological communities and represent a key component of ecosystem functioning. Pollination networks are expected to be more diverse and specialised in the tropics, but pollination ecology in these regions has been understudied in comparison to other areas.

The Cosmic Microwave Background Optical Depth Constrains the Duration of Reionization

The Astrophysical Journal Letters
Recently, it was pointed out that invoking a large value of the cosmic microwave background (CMB) optical depth, τ _CMB  = 0.09, could help resolve tensions between Dark Energy Survey Instrument DR2 baryon acoustic oscillation data and the CMB.

Cosmic 21-cm Fluctuations as a Probe of Fundamental Physics

, 2007
Fluctuations in high-redshift cosmic 21-cm radiation provide a new window for observing unconventional effects of high-energy physics in the primordial spectrum of density perturbations.

A somatic multiple myeloma mutation unravels a mechanism of oligomerization‐mediated product inhibition in GGPPS

The FEBS Journal, EarlyView.
Geranylgeranyl diphosphate synthase (GGPPS) plays a key role in multiple myeloma biology. Using crystallography, mass spectrometry, and fluorescence spectroscopy, this study shows that a somatic multiple myeloma cell line mutation destabilizes inter‐dimer interactions, resulting in increased GGPPS activity by facilitating product releas.

A patient‐derived orthotopic xenograft model unveils metastatic dynamics in head and neck squamous cell carcinoma

The FEBS Journal, EarlyView.
Metastasis in head and neck squamous cell carcinoma (HNSC) poses significant clinical challenges. This proof‐of‐concept study establishes patient‐derived orthotopic xenografts (PDOXs) as advanced models that closely replicate primary HNSC tumours, including local lymph node metastasis and the intricate cancer–stroma interaction.

Microtextures and structures in metal–sulfide grains in NWA 869 meteorite and their relation to thermal history of L‐chondrite parent body

Meteoritics &Planetary Science, Volume 60, Issue 3, Page 616-631, March 2025.
Abstract Results of microanalysis study of NWA 869 meteorite, an ordinary chondrite, where silicates, Fe‐Ni alloys, and troilite are major constituents, are reported. The presented study of microtextures in metallic and sulfide grains provides information on processes occurring from the asteroid's accretion, through the impacts until cooling.
