Study reveals how immune system of astronauts breaks down:
A recent study has shed light on the mechanisms behind the breakdown of the immune system in astronauts during space travel. The research, conducted by a team of scientists from various institutions, including NASA, investigated the changes in immune cells and gene expression patterns in astronauts who spent extended periods of time in space. The study found that prolonged space travel leads to alterations in immune cell function, including decreased activity of certain immune cells and increased inflammation. These findings have important implications for the health and well-being of astronauts during long-duration space missions, as well as for potential interventions to mitigate these effects.
Stonehenge-like 4,000-year-old sanctuary discovered in the Netherlands:
Archaeologists in the Netherlands have uncovered a Stonehenge-like sanctuary dating back approximately 4,000 years. The site, located in the province of Drenthe, consists of a circular arrangement of large stones and wooden posts, similar to the famous Stonehenge monument in England. The discovery provides new insights into the religious and ceremonial practices of the people who lived in the area during the Bronze Age. The structure is believed to have served as a gathering place for rituals and communal activities. Excavations at the site are ongoing, and researchers hope to learn more about the purpose and significance of the sanctuary through further analysis of the artifacts and remains found at the site.
These recent scientific findings highlight the ongoing exploration and discovery in fields such as space medicine and archaeology, expanding our knowledge of the universe beyond Earth and uncovering the mysteries of our past.
Archaeological Discovery and Astronaut Study
Archaeological Discovery
Archaeologists have discovered a 4,000-year-old sanctuary made up of ditches and burial mounds in the central Netherlands that they believe may have served a similar purpose to Stonehenge. Like the famous stone circle in southern England, the sanctuary - which was as big as at least three soccer fields and built with soil and wood - was built to align with the sun on the solstices.
Astronaut Study
Evidence is growing about the many ways that traveling in the microgravity environment of space tampers with the human body, with new research showing how it dials down the activity of genes in white blood cells crucial to the immune system. A study involving 14 astronauts who spent 4-1/2 to 6-1/2 months aboard the International Space Station found that gene expression in these cells, also called leukocytes, quickly decreased when they reached space and then returned to normal not long after returning to Earth, researchers said on Thursday.
