Mass Spectrometry Structural Proteomics Enabled by Limited Proteolysis and Cross‐Linking

open access: yesMass Spectrometry Reviews, Volume 45, Issue 4, Page 644-671, July/August 2026.
ABSTRACT The exploration of protein structure and function stands at the forefront of life science and represents an ever‐expanding focus in the development of proteomics. As mass spectrometry (MS) offers readout of protein conformational changes at both the protein and peptide levels, MS‐based structural proteomics is making significant strides in the

Mission Design and Early Navigation Operations for the Lunar Trailblazer Mission

open access: yesEarth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Lunar Trailblazer is a smallsat mission launched on 27 February 2025 as a secondary payload with the Intuitive Machines IM‐2 mission. After insertion into a near‐polar circular orbit around the Moon, the mission's goal was to search and characterize lunar water, primarily looking for ice in permanently shadowed craters and water bound in ...

Developing Workforce Capability in the Context of HR Ecosystem Learning

open access: yesHuman Resource Management Journal, Volume 36, Issue 3, Page 500-515, July 2026.
ABSTRACT For many organizations, developing workforce capabilities is central as it involves refining critical human resource processes such as upskilling or the acquisition of new profiles. These processes are becoming increasingly complex to manage as organizations collaborate within larger work ecosystems. Surprisingly, little research has addressed

Frequency‐Dependent Acoustic Reflection Coefficients of Flat Ground Assessed Using the Sonic Boom From the OSIRIS‐Rex Sample Return Capsule Recorded on Free Flying Balloons

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Low frequency sound can travel great distances in planetary atmospheres. When these waves reflect off the air/ground interface, energy may be absorbed or transferred to mechanical waves in the subsurface. This study describes the direct and reflected acoustic wave generated by the re‐entry of the OSIRIS‐REx Sample Return Capsule captured on a ...
