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

open access: yesExperimental Physiology, EarlyView.
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 ...

Kaempferol Attenuates Spaceflight‐Associated Knee Cartilage Degradation by Targeting NOX4‐Mediated Mitochondrial Dysfunction

open access: yesAdvanced Science, Volume 13, Issue 48, 28 August 2026.
We have shown that both simulated and actual spaceflight contribute to cartilage degradation in the knees of mice. Using RNA sequencing and bioenergetic profiling, we identified NADPH oxidase 4 (NOX4) as a key factor driving these changes. Additionally, we found that kaempferol, a naturally occurring flavonoid that binds directly to NOX4, reduces ...

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

open access: yesAstronomische 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.

Ground‐Based Solar Radio Observations From the Mexican e‐Callisto Stations During the May 2024 Extreme Space Weather Events

open access: yesSpace Weather, Volume 24, Issue 8, August 2026.
Abstract The period from 1 to 14 May 2024 was marked by some of the most intense solar activity of Solar Cycle 25, including multiple X‐class flares, fast coronal mass ejections (CMEs), and diverse solar radio emissions. We present observations from the Mexican e‐Callisto network (REC‐Mx), including long‐duration continuum emissions (CTMs), Type II ...

Vibrio Community Structure Shapes the Diversity of Carbenicillin‐Hydrolysing Class A β‐Lactamase Circulating in European Coastal Environments

open access: yesEnvironmental Microbiology, Volume 28, Issue 8, August 2026.
Vibrio communities shape carbenicillinase diversity in European coasts. Sediments serve as reservoirs of antibiotic‐resistant Vibrio alginolyticus, which can move into the water column and accumulate in bivalves. This spreads β‐lactamase resistance and raises human exposure risks to antibiotic‐resistant pathogenic Vibrio, especially as higher seawater ...

Dynamics of the disks of nearby galaxies [PDF]

open access: yesAstronomische Nachrichten, 2008
AbstractI describe how the dynamics of galactic disks can be inferred by imaging and spectroscopy. Next I demonstrate that the decomposition of the rotation curves of spiral galaxies into the contributions by the various components of the galaxies is highly degenerate.

Raman analysis of organic refractory materials after energetic processing: Evidence for amorphous carbon on TNOs and comets

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 8, Page 1994-2015, August 2026.
Abstract Amorphous carbon (αC) is found in various extraterrestrial particles, including those thought to originate from the outer Solar System. αC can form through two main processes involving C‐rich materials: exposure to energetic charged particles and thermal processing.
