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.

Solar Soft X‐Ray Proxy Derived From Observed Auger Photoelectrons by MGS and a 1999–2006 Flare Catalog at Mars

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract This study uses a novel approach to infer the solar soft X‐ray (SXR) irradiance from Auger photoelectron fluxes. Solar SXR irradiance is highly variable, particularly during solar flares. Solar SXR photons at ∼< ${\sim} < $2.5 nm produce oxygen Auger photoelectrons by photoionizing atmospheric constituents. More specifically, we derive the fit

Evaluation of Particle Scattering by Locally Generated Fast Magnetosonic Waves in the Martian Ionosphere

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Locally generated fast magnetosonic (local MS) waves in the Martian ionosphere have been reported recently, which are different from the solar wind‐driven MS waves. However, their effects on particle scattering have not been reported yet. This study pioneers the investigation of electron, proton, and oxygen atomic ion scattering induced by ...

Laser Ablation Sampling With Low‐Power Plasma: A LA‐MIP‐MS Instrument for Spaceflight

Rapid Communications in Mass Spectrometry, Volume 40, Issue 3, 15 February 2026.
ABSTRACT Rationale Inductively coupled plasma (ICP) is a commonly used ion source for mass spectrometry‐based chemical analysis of a wide range of materials. Traditional ICP ion sources use high power (> 1000 W) and significant gas flow (> 10 L/min), rendering them unsuitable for spaceflight, as they are too resource‐intensive for planetary spacecraft.

Single‐Cell Metabolic Imaging Reveals Glycogen‐Driven Adaptations in Endothelial Cells

Advanced Science, Volume 13, Issue 7, 3 February 2026.
Single‐cell metabolic imaging of diabetes‐associated endothelial dysfunction by SRS microscopy reveals dynamic glycogen storage and its role in modulating metabolic adaptations under glucose starvation. Abstract Endothelial dysfunction (ED) is a defining feature of diabetes mellitus (DM) and a key contributor to many metabolic and cardiovascular ...

Cancer Stem Cells Shift Metabolite Acetyl‐Coenzyme A to Abrogate the Differentiation of CD103+ T Cells

Advanced Science, Volume 13, Issue 8, 9 February 2026.
Lei et al. demonstrate that cancer stem cells (CSCs) play a pivotal role in impairing the differentiation of CD103+ T cells in patients with non‐small‐cell lung cancer. The key mechanism involves CSC‐derived acetyl‐CoA, which disrupts CD103+ T cell differentiation by sequentially inducing acetylation and ubiquitination of the Blimp‐1 protein. Targeting

Effectiveness of Multivitamins vs Folic Acid on Prevention of Neural Tube Defects in Mouse Genetic Models and Human Organoids

Advanced Science, Volume 13, Issue 8, 9 February 2026.
Folic acid (FA) and multivitamins/minerals (MVM) are recommended for the prevention of neural tube defects (NTDs). Using a novel human neural tube‐like organoid system and mouse models, the study compares the effectiveness of two supplements on NTDs and cellular behaviors.

Successful conservative management of an intravesicular haematoma in a cat with prior urethral obstruction

Veterinary Record Case Reports, Volume 14, Issue 1, February 2026.
Abstract An 8‐year‐old male neutered domestic shorthair cat was presented for the management of severe anaemia and post‐urethral obstruction care. A large intravesicular lesion, which was suspected to be a haematoma, was identified via abdominal ultrasound. This was suspected to be secondary to bleeding in the urinary tract.
