A new study has revealed that excavated soils from urban construction sites represent a previously overlooked source of greenhouse gas emissions, while also highlighting practical strategies to significantly reduce their climate impact.

Coastal wetlands are among the planet’s most effective natural carbon sinks, but their ability to store carbon is increasingly threatened by climate change and human activity. Now, a new field study suggests that adding biochar to these ecosystems could significantly boost their carbon storage capacity, with tidal forces playing a surprisingly beneficial role.

Despite decades of archaeological research, the origins of iron metallurgy in sub-Saharan Africa remain largely unclear. Yet this technological revolution—crucial for producing efficient agricultural tools—emerged there at least 3,000 years ago. While investigating an archaeological site in eastern Senegal, an international team led by the University of Geneva (UNIGE) uncovered exceptionally well-preserved remains of an ironworking workshop dating back to the 4th century BCE and used for nearly eight centuries. The discovery, published in African Archaeological Review, provides new insights into late prehistoric metallurgical practices in Africa.

Newly discovered rock art depicting Tasmanian tigers and Tasmanian devils in northern Australia is providing fresh insights into their cultural importance and when they may have last roamed mainland Australia. 

The project, led by Griffith University Chair in Rock Art Research, Professor Paul Taçon, in partnership with Traditional Owners, documented 14 new images of the Tasmanian tiger or thylacine, as it also known, and two of the Tasmanian devils from two locations in northwest Arnhem Land, Northern Territory. 

Tasmanian devils and thylacines are widely believed to have disappeared from mainland Australia about 3,000 years ago. The newly documented artworks—some of which may be less than 1,000 years old—raise the possibility that these species survived longer in northern regions than previously thought.

Approximately 3,500 years ago, in the Bronze Age settlement of Cabezo Redondo in present-day Villena, a fire razed dwellings and workshops to the ground. However, the same fire that destroyed part of the village also helped preserve an object that is incredibly hard to document in archaeology: a loom with a largely wooden structure.

Recently published in the journal Antiquity, this finding by a team of researchers from several Spanish universities is one of only a few known cases in Mediterranean Europe in which both the set of loom weights and components made from wood and plant fibres have been preserved.

Classifying ancient pottery has always depended on the trained judgment of an archaeologist. Identifying the subtle differences between piece types takes years of experience, and two experts will not always agree. Now, a team including researchers at Nagoya University in Japan has developed a deep learning model that can classify pottery by shape with high accuracy, using three-dimensional scan data rather than photographs or drawings.
