Optimal neuromuscular performance requires motor neuron phosphagen kinases

The Journal of Physiology, Volume 604, Issue 5, Page 2027-2059, 1 March 2026.
Abstract figure legend Motor neuron (MN) terminals in fruit flies, mice and humans contain phosphagen kinases, a key enzyme in their energy storage and buffering system. Here we knocked down the primary phosphagen kinase in fruit fly larvae (arginine kinase 1 (ArgK1)) but were surprised to find that MN endurance was unaffected.

Galileo PLS Plasma Observations During the E12 Europa Flyby Refuting an Encounter With a Cryovolcanic Plume

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract During Galileo's closest (“E12”) flyby of Europa, a brief burst of wave activity was recorded by the plasma wave instrumentation, PWS. This was speculatively interpreted by Jia et al. (2018, https://doi.org/10.1038/s41550‐018‐0450‐z) as a 2,100 cm−3 spike in plasma densities from a water plume encounter. While the plasma instrument, PLS, could

JWST Discovers the Vertical Structure of Uranus' Ionosphere

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract On 19 January 2025, the James Webb Space Telescope (JWST) program # $\mathrm{\#}$5073 observed Uranus for almost a full rotation with NIRSpec. We present the first ever vertical ionospheric profiles of H3+ ${\mathrm{H}}_{3}^{+}$ temperature, volumetric density and total emission.

Martian Atmospheric Loss Through Foreshock Transient Events

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract At Mars, the MAVEN spacecraft has made observations of Hot Flow Anomalies (HFAs) in the foreshock. Due to the bow shock's proximity to the planet, it is theorized that HFAs contribute to atmospheric escape at Mars through the excavation of ionospheric ions.

Microconcentrator Solar Panel Architectures Achieving High Specific Power for Deep Space Missions

Solar RRL, Volume 10, Issue 4, 26 February 2026.
Microconcentrator photovoltaics (microCPV) are emerging as a promising solution for powering spacecraft in deep space, where conventional solar arrays are challenged by extremely low‐intensity, low‐temperature conditions. This work presents the design, development, and characterization of two optical architectures aiming at maximizing specific power (W/
