A STEP IN STONE. ONTOLOGIES OF PODOMORPHIC PETROGLYPHS IN SOUTHERN SCANDINAVIAN BRONZE AGE

Oxford Journal of Archaeology, EarlyView.
Summary During the Bronze Age, a particular type of podomorphic petroglyph was produced on the outcrops by the sea in southern Scandinavia. In this text, their distribution, organization and articulation are analyzed in the Mälaren region of central‐eastern Sweden.

In Situ Measurements of Thermal Environment on the Moon's Surface Revealed by the Chang'E-4 And Chang'E-5 Missions

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The thermal environment of the lunar surface is of crucial importance for the lander thermal design and the interpretation of scientific data. Clarifying the radiative sources and intensity on the outer surface of the lander is one of the key aspects of ...

The role of antibiotics in preventing surgical complications in periodontology and implant dentistry

Periodontology 2000, EarlyView.
Abstract Antibiotics are commonly prescribed in periodontal and implant surgeries, either before, during or after surgery, to prevent postoperative infection and reduce early implant failure. However, the potential benefits may be undermined by the risks of resistance and sensitization, thus requiring a strict indication for prescription.

Donor retention and return patterns in Saudi Arabia: Implications for blood safety and supply stability

Transfusion Medicine, EarlyView.
Abstract Background Sustaining a safe and sufficient blood supply requires not only recruiting first‐time donors but also retaining them over time. In Saudi Arabia, donor retention remains poorly understood, with limited data on return behavior, demographic influences, and temporal trends.

Impact plasma amplification of the ancient lunar dynamo

Science Advances
Spacecraft magnetometry and paleomagnetic measurements of lunar samples provide evidence that the Moon had a magnetic field billions of years ago. Because this field was likely stronger than that predicted by scaling laws for core convection dynamos, a longstanding hypothesis is that an ancient dynamo was amplified by plasma from basin-forming impacts.

Women in space: A review of known physiological adaptations and health perspectives

Experimental Physiology, EarlyView.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

Subsoil structure at the Chang’E-6 landing site revealed by in-situ Lunar Regolith Penetrating Radar

Communications Earth & Environment
As humanity’s first sample return mission from the lunar farside, China’s Chang’E-6 mission provides a unique window into understanding the dichotomy in lunar nearside-farside evolution. Chang’E-6 landed in the southwestern Apollo basin (~2.79 Ga) within

Spaceflight and sport science: Physiological monitoring and countermeasures for the astronaut–athlete on Mars exploration missions

Experimental Physiology, EarlyView.
Abstract Long‐duration spaceflight impacts essentially every system in the human body, resulting in multisystem deconditioning that might impair the health and performance of crewmembers, particularly on long‐duration exploration missions to Mars. In this review, we apply the sport science model of athlete monitoring, testing and training to astronauts;
