Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, Volume 111, Issue 9, Page 4015-4040, 1 September 2026.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

An Extreme Solar Millimeter Burst Induced by Two Successive Flares

The Astrophysical Journal Letters
How flares accelerate electrons efficiently remains a major puzzle in solar and stellar astronomy. Crucial information is carried by microwave bursts that are generated as energetic electrons spiraling around magnetic field lines.

Peak-intensity energy spectra of intense solar energetic electron events measured with Solar Orbiter in 2020–2022

Astronomy & Astrophysics
Context. The energy spectra of energetic particles offer valuable insights into particle acceleration processes. While the commonly observed spectral breaks in solar energetic electron (SEE) spectra could serve as fingerprints of the acceleration process,

Lunar Dayside Surface Potentials in the Terrestrial Magnetotail Inferred From Comparing Observed and Modeled Photoelectrons

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract As an airless body, the lunar surface is charged as a result of balancing electric currents into and away from the surface. Lunar surface charging is important for both scientific and human‐exploration purposes. The nightside surface charging has been well characterized by previous studies, but less so for the dayside.

The ORCA‐TWIN qCMOS Experiment I. Science Case and Commissioning at Calar Alto Observatory

Astronomische Nachrichten, Volume 347, Issue 7, August 2026.
ABSTRACT We describe a pilot study to explore a new generation of fast and low noise CMOS image sensors for time domain astronomy, using two remote telescopes with a baseline of 1635 km. The experiment involves direct imaging with novel qCMOS image sensor technology that combines fast readout with sub‐electron readout noise.

Effect of structuring on coronal loop oscillations [PDF]

, 2007
In this Thesis the theoretical understanding of oscillations in coronal structures is developed. In particular, coronal loops are modelled as magnetic slabs of plasma.

Signatures of Confined and Eruptive Solar Flares in Microwave Spectra

The Astrophysical Journal
Abstract We describe how microwave spectra of confined flares differ from those of eruptive flares. All 29 confined ≥M1.4 soft X-ray flares from NOAA Active Region 12192 in 2014 October that were observed by the Radio Solar Telescope Network in the >300 MHz microwave range (encompassing RSTN frequencies from ...

Responsive nitric oxide‐releasing antibacterial materials for biofilm‐associated infections: Mechanisms, design strategies, and applications

Responsive Materials, Volume 4, Issue 3, August 2026.
This review summarizes the recent progress in responsive NO‐releasing materials and their applications in biofilm‐associated infectious diseases. The design principles and response mechanisms are given to provide inspiration toward the future development of multi‐responsive NO‐releasing materials.

One-Minute Quasi-Periodic Pulsations during an M-Class Solar Flare

, 2022
We study the Quasi-Periodic Pulsations (QPPs) of an M4.4 class solar flare, which occurred in active region NOAA 11165 on 8 March 2011. With the Fast Fourier Transform (FFT) method, we decompose the flare light curve into fast- and slowly-varying ...
