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 ...

Design, commissioning and performance of a device to vary the turbulence in a recirculating flume

, 2013
Ambient turbulent flow structures are one of the key drivers that will determine the rate of wake recovery downstream of tidal turbines. For second and third generation arrays or farms such a parameter is critical for the determination of inter-device ...
