Veronica paczoskiana is no more than a pine forest ecotype of V. spicata that evolved independently in forest‐steppes of Ukraine and the Altai region

open access: yesNordic Journal of Botany, EarlyView.
The Eurasian steppe area has been a dynamic vegetation biome during the Pleistocene with its repeated cycles of forest advances and retreats. Such a scenario allows the evolution of ecotypes at the ecotone with the potential for parallel evolution in different parts of the distribution area.

Subsurface Investigations of Cryo‐Hydrogeological Features in a High Arctic Catchment Under Transition

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT In this study, the internal structure and seasonal variations of cryo‐hydrogeological features were investigated in the Fuglebekken catchment, located near the Polish Polar Station Hornsund in Svalbard. Over a few years, rising air temperatures and intensified water circulation have significantly altered the distribution, extent, and state of ...

Light‐Modulated Humidity Sensing in Spiropyran Functionalized MoS2 Transistors

open access: yesSmall, EarlyView.
A hybrid material combining molybdenum disulfide (MoS2) and spiropyran for humidity and light responsiveness is developed. Ultraviolete (UV) irradiation tunes the wettability of MoS2 decorated by spiropyran, enhancing the humidity sensitivity. Water adsorption and photochromic doping significantly alter the optoelectronic properties of MoS2 flakes ...

Renovating Neural Networks With Viral‐Mediated Gene Transfer From A Tissue Contacting Matrix Mimic

open access: yesSmall, EarlyView.
Fmoc‐DDIKVAV self‐assembling peptidemediated delivery of AAV‐BDNF significantly enhances neuroprotection in the striatum of a mouse model compared with AAV‐BDNF injection alone. This synergistic integration of biomaterial scaffolding and gene therapy holds substantial promise for slowing the progression of neurodegenerative diseases such as Huntington ...
