Testicular histopathology and its association with germ cell numbers, serum concentrations of reproductive hormones, and semen quality

open access: yesAndrology, Volume 14, Issue 8, Page 2388-2400, November 2026.
Abstract Background It is well‐established that spermatogenesis, semen quality, and reproductive hormones are interlinked. It is, however, less well‐described how various specific testicular histopathologies are linked to reproductive hormones and semen quality.

Nitrogen Radical Photocatalysed Reduction of Nitrous Oxide

open access: yesAngewandte Chemie, Volume 138, Issue 42, 12 October 2026.
This work offers the first example of reduction of the potent greenhouse gas N2O to the benign products N2 and O(Bpin)2 using a nitrogen‐based catalyst. The active catalyst is shown to be a nitrogen‐based radical which operates under photocatalytic conditions.

LMTK2 Inhibits Metastasis of Colon Cancer Cells Through p38 MAPK

open access: yesCancer Science, Volume 117, Issue 11, Page 3039-3051, November 2026.
LMTK2 suppresses colon cancer metastasis by acting as a kinase‐independent scaffold that directly binds p38, blocking its interaction with MKK3/6 and subsequent phosphorylation, thereby inhibiting the downstream pro‐metastatic gene program. ABSTRACT Metastasis is the leading cause of death in patients with colon cancer. Although Lemur tyrosine kinase 2

Decreased Expression by a Chemically Modified siRNA to PTBP1 Seriously Affects Warburg Effect in Colorectal Cancer Cells

open access: yesCancer Science, Volume 117, Issue 11, Page 3052-3070, November 2026.
Chemically modified siR‐PTBP1 disrupts the Warburg effect by reprogramming pyruvate kinase splicing from PKM2 to PKM1. This metabolic shift activates the TCA cycle, increases ATP production, and excessive ROS generation, and ultimately induces apoptotic cell death in colorectal cancer cells.

Reduction of Tree Water Stress by Large Herbivores in an African Savanna

open access: yesEcology Letters, Volume 29, Issue 11, November 2026.
Using a long‐term herbivore exclusion experiment across a rainfall gradient, we found that excluding large mammals increased savanna tree growth but elevated water stress. Tree sensitivity to exclusion varied among species with contrasting water‐use strategies, indicating that physiological responses may drive shifts in tree communities under altered ...
