A significant improvement in the ecological environment of Al-Ahsa Oasis, Saudi Arabia, has been observed from 1987 to 2021, with a notable increase in vegetation cover. This was evidenced by an increase in Normalized Difference Vegetation Index (NDVI) values exceeding 0.10, particularly in the 'green' zones where NDVI values surpassed 0.40. The study, using Landsat satellite images and ground validation points, found that while low NDVI areas remained stable, high NDVI regions expanded, especially in northern and southern parts of the oasis from 2002 to 2021. High accuracy (92%) was achieved in detecting vegetation cover changes. The research suggests that strengthening forestry projects could help combat sand encroachment and further enhance the oasis's ecological environment.

Historical analysis reveals that major nuclear accidents, including the Bikini Atoll Nuclear Test Site incident, have consistently hindered civilian nuclear initiatives, complicating the debate on nuclear energy's role in mitigating climate change. Serhii Plokhy's book examines six nuclear disasters—Bikini Atoll (1950s), Kyshtym (1957), Windscale (1957), Three Mile Island (1979), Chernobyl (1986), and Fukushima (2011)—through comprehensive research and firsthand accounts, balancing technical details with human narratives. The study underscores the paradox of nuclear energy: while its potential to address climate change is significant, repeated accidents have eroded public trust and slowed progress. Plokhy argues that these disasters, far from being secrets, have shaped global perceptions, making it challenging to envision a world without their impact.

A comprehensive analysis of cippes and monuments from Dougga, Tunisia, reveals significant insights into ancient funerary practices and social hierarchies. The study, the first to focus extensively on these often-overlooked artifacts, categorizes them based on function (votive or funerary) and form, while examining architectural and iconographic details. It also maps their spatial distribution, distinguishing between in-situ autels and those found out of context. By tracing the historical context of excavations and analyzing inscriptions, the research reconstructs the social origins and ranks of the deceased, offering a nuanced understanding of Dougga's ancient society.
