Evidence That the Protein Phosphatase Activity of PTEN Contributes to Embryonic Development and Tumor Suppression

open access: yesCancer Science, EarlyView.
Mice expressing only mutant PTEN Y138L, a protein which shows normal suppression of cellular AKT yet lacks protein phosphatase activity, die in utero, and heterozygous mice display a range of tumors. This indicates both the lipid and protein phosphatase activities of PTEN work together for normal tumor suppression and embryonic development.

Effects of DEM Resolution on Hectare‐Scale Potential Soil Loss Modelling: A Case Study Using a Spatially Distributed Erosion Model

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 10, October 2026.
DEM resolution alters not only mean modelled soil loss but also its spatial redistribution at hectare scale. Using a spatially distributed erosion model, we show that changes in cell size modify slope, flow‐path length and run‐off concentration, producing non‐linear changes in erosion and deposition patterns.

Controllable Gradient Structures Toward Enhancing Ion Transport Kinetics in Lithium Metal Anodes: A Review

open access: yesCarbon Neutralization, Volume 5, Issue 5, September 2026.
This review summarized various gradient structures across the electrolyte, solid‐electrolyte interphase, and Li+ nucleation interfaces. Furthermore, the design principles of various gradient structures and their underlying mechanisms for optimizing lithium‐ion transport kinetics were systematically elucidated. ABSTRACT The slow kinetics of lithium ions

Shaping the rhizosphere: How barley domestication altered root traits and microbiome interactions

open access: yesCrop Science, Volume 66, Issue 5, September/October 2026.
Abstract Climate change and soil degradation are rapidly transforming agricultural systems, underscoring the need for a deeper understanding of how crops interact with their surrounding microbiomes. Barley, as one of the earliest domesticated cereal crops, serves as a valuable model for investigating the effects of domestication on root traits ...
