Chemical Upcycling of Nitrile Butadiene Rubbers to Polyamines and Polyols by Chemoselective Catalytic Hydrogenation

Angewandte Chemie, Volume 138, Issue 18, 27 April 2026.
We demonstrate here the transformation of NBR (Nitrile butadiene rubber) including post‐consumer waste sourced from nitrile gloves and o‐rings into polyamines and polyols via ruthenium catalyzed hydrogenation. ABSTRACT We report here two new approaches for the chemical recycling/upcycling of nitrile butadiene rubber (NBR) to make either polyamines or ...

The MdICE1/MdFAMA‐MdTYDC Transcriptional Module Confers Cold Tolerance by Regulating Dopamine Metabolism in Apple

Plant Biotechnology Journal, Volume 24, Issue 5, Page 3012-3031, May 2026.
ABSTRACT Low temperature is a critical abiotic stress that imposes major constraints on the sustainable development of the fruit tree industry. Although exogenous dopamine has been shown to enhance cold tolerance in plants, its molecular mechanisms in apple (Malus domestica) remain poorly understood.

Acceptorless Dehydrogenative Polymerization

Angewandte Chemie, Volume 138, Issue 18, 27 April 2026.
Acceptor‐less dehydrogenative polymerization (ADP) enables the atom‐economic step‐growth synthesis of different type of polymers directly from simple alcohols, releasing H2 as the sole by‐product. This review outlines the mechanistic foundations, catalytic systems, and emerging polymer architectures of ADP, highlighting its potential as a sustainable ...

Untargeted Metabolomics Coupled With Machine Learning Unravels Crop‐Specific Versus Generalized Effects of Biostimulants in Cucumber, Pepper, and Tomato

Physiologia Plantarum, Volume 178, Issue 3, May/June 2026.
ABSTRACT In recent years, agricultural practices have shifted toward sustainability, aiming to reduce the use of agrochemicals and rely more on bio‐based solutions. However, the effectiveness of these latter suffers from inconsistency. Understanding how different crops respond to biostimulants, instead of referring to a specific trial or crop, is a ...

Metabolomic responses are more sensitive in muscle than serum following 28 days of arduous exercise with erythropoietin administration

Experimental Physiology, Volume 111, Issue 5, Page 2613-2626, 1 May 2026.
Abstract Erythropoietin (EPO) administration stimulates haematological and non‐haematological adaptations that alter substrate oxidation and enhance aerobic performance. The effects of strenuous exercise and EPO on metabolites, and whether any effect is associated with haematological and non‐haematological adaptations, has not been assessed.

Innate Immunity and Microbial Recognition in Reproduction: From Barrier Defense to Maternal–Fetal Tolerance

The FASEB Journal, Volume 40, Issue 8, 30 April 2026.
Graphical abstract illustrating the barrier defense–tolerance framework of reproductive innate immunity. Across the female and male reproductive tracts and the maternal–fetal interface, epithelial barriers, innate sensors, immune cells, and microbial signals are integrated to preserve reproductive homeostasis.
