A Meta‐Analysis on Environmental Triggers of Spawning Migrations Reveals a New Classification of Thermal Guilds in European Freshwater Fishes

Fish and Fisheries, Volume 27, Issue 3, Page 478-495, May 2026.
ABSTRACT Fish migration through river networks is essential for completing life cycles and accessing critical habitats, but fragmentation increasingly disrupts spawning movements. In Europe, over one million barriers limit connectivity and create trade‐offs between ecological integrity and human uses, such as hydropower, flood control, fisheries and ...

Effects of Hold Time on the Elevated Temperature Fatigue Crack Growth Behavior of Alloy 247LC‐DS

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 5, Page 1794-1808, May 2026.
ABSTRACT Creep–fatigue crack growth (CFCG) experiments were performed at 850°C and 950°C on nominally 12.70‐mm‐thick compact‐type specimens of alloy 247LC‐DS, a Ni‐base superalloy. The loading cycles consisted of trapezoidal waveforms with hold times of 2 and 20 min at the maximum force.

Effect of Matrix Properties on Quasi‐Static and Fatigue Properties of Thermosetting Polyurethane and Its GFRP Composites

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 5, Page 1929-1943, May 2026.
ABSTRACT In this study, the influence of resin cross‐link density on thermomechanical properties and fatigue behavior of polyurethane resins and glass fiber‐reinforced polyurethane (PUR‐GFRP) composites was investigated. This material is a candidate for renewable energy applications like rotor blades in wind turbines.

Bed rest decreases resting skeletal muscle O2 uptake and resting energy expenditure in young and elderly subjects

Experimental Physiology, Volume 111, Issue 5, Page 2599-2612, 1 May 2026.
Abstract A decrease in resting muscle O2 uptake (V̇O2m${\dot V_{{{\mathrm{O}}_2}{\mathrm{m}}}}$) described during bed rest (BR) could determine a decreased whole‐body resting energy expenditure (REE), potentially useful during prolonged spaceflights. Two groups of recreationally active men (young [Y], n = 8, age 23 ± 5 years; elderly [E], n = 10, age ...

Exploring the Environmental Sustainability of Primary Al–Air Batteries for Long‐Term Energy Storage Applications

ChemSusChem, Volume 19, Issue 8, 28 April 2026.
An exploratory life cycle assessment compares aluminum–air batteries with gaseous and liquefied hydrogen for long‐term energy storage. The results reveal strong trade‐offs between climate benefits, resource burdens, and system efficiency, highlighting key hot spots and showing how decarbonized smelting and circular material flows can improve the ...
