Shortwave Infrared Microimaging Spectroscopy of the Martian Meteorites

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Until samples from the Martian surface are successfully brought to Earth, meteorites represent the only opportunity to perform laboratory analyses on Martian material. Microimaging spectroscopy of the Martian meteorite suite provides a valuable means to better understand infrared data collected remotely from the Martian surface. This rapid and

Altered Cytokine‐Induced STAT3 and STAT5 Activation of Peripheral T Follicular Helper Cells Contributes to Vaccine‐Non‐Responsiveness in Aging and HIV

Aging Cell, Volume 25, Issue 3, March 2026.
Chronic immune activation and inflammation associated with aging and HIV skew Tfh signaling toward enhanced IL‐2–STAT5 activation, reinforcing IL‐2R expression through a positive feedback loop and suppressing Tfh helper differentiation programs, thereby contributing to impaired vaccine responsiveness.

Probabilistic Mixture Model-Based Spectral Unmixing

Applied Sciences
Spectral unmixing attempts to decompose a spectral ensemble into the constituent pure spectral signatures (called endmembers) along with the proportion of each endmember.

Single‐molecule validation and optimised protocols for the use of secondary nanobodies in multiplexed immunoassays

Journal of Microscopy, Volume 301, Issue 3, Page 422-436, March 2026.
Abstract Recently developed secondary nanobodies or single‐domain antibodies present a powerful tool for immunodetection. Unlike traditional antibodies, their monovalence enables pre‐association with primary antibodies prior to sample staining, presenting a straightforward affinity‐based antibody labelling solution.

Unraveling the Enrichment Mechanisms of Rare Earth Elements in Deep‐Sea Sediments: An Environmental Magnetic Perspective

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Deep‐sea rare earth elements and yttrium (REY)‐rich sediments have attracted considerable attention since their discovery in 2011. However, the environmental factors controlling REY enrichment remain poorly understood, largely because paleoceanographic proxies are absent in pelagic clays.

Robust Multiscale Spectral–Spatial Regularized Sparse Unmixing for Hyperspectral Imagery

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
With the aid of endmember spectral libraries, sparse unmixing plays a critical role in interpreting hyperspectral remote sensing data. Integrating spatial clues from hyperspectral data into sparse unmixing frameworks is pivotal for enhancing unmixing ...
